Description

  The present invention relates to a transfer device for cutting branches for transferring, for example, tea leaves to be harvested or tea branches to be trimmed for tea bowl shaping on a cutting device, and a cutting device including the same, in particular. The present invention relates to a new device that facilitates confirmation of the state of transfer of tea leaves and the like, the subsequent housing state, and the rear state of the cutting device.

For example, so-called riding-type tea mowers are widely used for harvesting work on teacups. This is a traveling machine body that travels across a teacup, a reaping machine body that is attached to the traveling machine body and directly performs the harvesting operation, and a housing part that is provided at a subsequent stage of the reaping machine body and that can accommodate the harvested cutting leaves. And a transfer device that transfers the harvested branches and leaves from the harvesting machine body to the storage unit, and performs tea garden management or the like according to the purpose.
This transfer device has a slit jet type mechanism that the applicant of the present invention designates as a trademark, and the cutting branches and leaves cut by the reaping machine body are evacuated by the transfer air flowing in the transfer duct of the transfer device. Once lifted and transferred, it is sent to a storage unit to which a container or the like behind the mounting device is applied.

As for such a transfer device, there are some restrictions mainly in terms of space in configuring it, and as a result, the following configuration is mainstream to avoid this restriction, and the technology Established as common sense.
That is, as disclosed in Japanese Patent No. 4349999 “Transferring method of tea branch and leaf, its transfer device, and a tea mower having the same” as Patent Document 1, the transfer duct extending substantially vertically upward from the rear of the mowing device is Since the space for supplying the transfer air to the surroundings could not be easily secured, first, a part of the air duct for supplying the transfer air over the entire cutting width was made flat, and the rear rear surface of the transfer duct It is arranged here using a small space.

On the other hand, the flexible blower hose for supplying the conveyance air to the blower duct has a considerably large diameter in relation to the required blown amount, and as a rational arrangement thereof, as disclosed in the above-mentioned Patent Document 1, transfer The upper center of the duct is divided to secure a connection space with the air duct, and this aspect has been established as technical common sense.
However, on the other hand, according to the original function of the transfer duct, the transfer pipeline which is the internal space of the transfer duct has a shape branched in the middle of the ascending transfer. In other words, the shape in which the transfer pipeline is sufficiently secured in the width direction has a shape in which a partition wall-like branching portion that inhibits transfer is present in the middle.
For this reason, during actual work, if the cutting size is short, smooth transfer is performed, but if an unexpectedly long cutting size or a vine-shaped item is cut off, the shunting part will stay. Sometimes it happened.

For this reason, the transfer duct has been desired to have a single tubular shape that does not branch upstream, but due to the above technical restrictions, it is not provided as a real machine on the market.
Of course, a transfer duct of a type that does not branch has also been proposed in Patent Document 1, but in order to obtain a practically satisfactory operating state, a specific arrangement mode of the blower hose and an arrangement mode of related members There is a need for further technical solutions, and in reality, no provision has been made to the market. As a result, an upper branch type transfer duct is recognized as the best form, and this layout is followed by a fixed concept.

In view of such a background, the present inventors should realize that the transfer duct has a single tubular shape that does not branch in the middle so that the cut branches can be smoothly transferred even if they are long. In spite of the above various restrictions, new aspects have been intensively developed with regard to the configuration and arrangement of related members under a new focus.
On the other hand, when such a single-tube type transfer duct is used, the field of view behind the cutting device is completely blocked, and the tea leaves to the container (container) disposed behind the transfer duct in the cutting device. It is impossible to visually check the state of the cutting branches and the like.

It is a perspective view which shows the transfer apparatus of this invention, and the reaping apparatus of this invention to which this is applied. They are a side view (a) and a front view (b). It is a disassembled perspective view which shows the transfer apparatus of this invention. It is the front view (a) which shows the transfer apparatus of this invention, a side view (b), and a rear view (c). It is explanatory drawing which shows a mode that the tea branch leaf immediately after cutting is lifted and conveyed substantially right above a cutting blade by making upward conveyance wind act from the cutting blade back.

The best mode of the present invention is as described in the following examples. In the description, first, the whole structure will be schematically described with reference to a plucking machine as an example of the harvesting device of the present invention, and the harvesting branch leaf transfer device which is the present invention device will also be described. In addition, as this plucking machine, a so-called large-sized riding type plucking machine (branch-plucking type plucking machine 1) in which the cut tea leaves A are lifted and transferred and accommodated in the accommodating portion will be described as an example.
Incidentally, the transfer method itself of the present invention can be used not only for plucking the tea buds, but also for pruning work for pruning the trunks in order to prepare the tree shape and restore the state of the tree. The term “tea branch leaf” described in the name of the present invention, claims, etc. is a general term for the picked tea leaf A and the pruned branch trunk (the tea branch leaf is also given the same symbol A as the tea leaf). The term “tea mower” or “tea mower” is a general term for plucking (plucking machine) and pruning (pruning machine). A specific form of the pruning operation will be described later.

  As shown in FIGS. 1 and 2, a teacup straddle-type plucking machine 1, which is an example of a cutting device including the transfer device of the present invention, and a traveling machine body 2 that travels across a teacup T, and this traveling machine body. 2, a reaping machine body 3 supported so as to be positioned on the upper surface of the teacup T, a housing part 4 which is provided behind the reaping machine body 3 and accommodates the plucked tea leaves A, and a pruning tea leaf A is accommodated from the reaping machine body 3 And a transfer device 5 for transferring up to 4. Hereinafter, each component will be described.

  First, the traveling machine body 2 will be described. This is one that travels on the ground between the teacups T across the teacup T, and has a frame 21 that is formed in a gate shape when viewed from the running direction. The frame 21 includes a leg frame 21A provided in a standing state between the ribs, a connecting frame 21B that connects the leg frames 21A, and a lifting bracket 21C that is attached to the leg frame 21A so as to be movable up and down. Is. And the traveling body 22 which applied the crawler as an example is provided in the lower end of the leg part frame 21A. Of course, the traveling body 22 is not limited to such a crawler, but a form in which a pneumatic tire that does not excessively press the saddle, or both are applied (for example, a form in which a pneumatic tire is applied to the front side and a crawler is applied to the rear side). Etc. can be taken as appropriate.

  Further, in the upper part of the connecting frame 21B, in order to perform control and operation of the operator seat 23, the control stick 24, and the teacup straddle-type plucking machine 1 on which an operator who rides on the teacup straddle-type picking machine 1 sits. The control box 25 is provided. A motor 26 to which, for example, a diesel engine is applied is mounted on the side of the driver's seat 23. As an example, a hydraulic pump (not shown) is driven by the motor 26 and supplied by the hydraulic pump. The hydraulic oil is used to drive the traveling body 22, drive a cutting blade 31 of the reaping machine body 3 to be described later, and further drive a cylinder (not shown) that is responsible for the lifting and lowering movement of the lifting bracket 21C.

A blower 27 is provided on the connection frame 21B to blow the tea leaves A cut by the cutting blade 31. The blower 27 is directly driven by the prime mover 26. And from this air blower 27, a pressure wind is supplied to the transfer apparatus 5 (the mowing machine body 3 side) via the air duct 28. FIG. Note that a part or the whole of the air duct 28 is constituted by an air hose 28 </ b> A to which a flexible duct is applied, and is connected to the transfer device 5.
In this embodiment, as shown in FIG. 2B, the blower 27 is disposed on the left side of the prime mover 26, that is, substantially in the center of the traveling machine body 2 in a front view. Since the introduction port 77 of the duct 7B is located at the right end in the front view, the blower 27 may be disposed on the right side of the prime mover 26 in the front view.

  Next, the reaping machine body 3 will be described. This substantially plucks the tea leaves A, and includes the cutting blade 31 as a main member. The cutting blade 31 includes, for example, a pair of upper and lower cutting blade bodies 32, a cutting blade support frame 33 that slidably supports the cutting blade bodies 32, and a reciprocating sliding of the cutting blade body 32 with an eccentric plate, an eccentric shaft, or the like. The pair of upper and lower cutting blade bodies 32 are alternately reciprocated to cut the tea leaves A by the clipper action of the blades (teeth) formed on each cutting blade body 32.

  Thus, the cutting blade 31 takes the form of a so-called cassette-type replacement blade in which the cutting blade body 32, the cutting blade support frame 33, the drive unit 34, and the like are assembled together, and can be easily picked by replacing the cutting blade 31. The specification can be changed from a machine to a pruning machine such as a shallow mower or an intermediate mower. Reference numeral 35 in the figure denotes a side plate portion that detachably holds such a cassette-type cutting blade 31. The side plate portion 35 is supported by the elevating bracket 21C, and the height of the cutting blade 31 is set freely. It can be configured.

The drive unit 34 of the cutting blade 31 is preferably driven by hydraulic oil supplied from the hydraulic pump (driven by the prime mover 26 mounted on the traveling machine body 2). The driving of can also be performed by an engine separately.
The cutting blade 31 is not necessarily limited to such a clipper type, and for example, a rotary rotary blade can be applied.

  Next, as an example of the storage unit 4 that stores the tea leaves A cut by the cutting blade 31, as shown in FIGS. 1 and 2, a container having a frame unit 41 that forms a frame as a main member is employed.

  Next, the transfer device 5 of the present invention will be described. The transfer device 5 is a part that transfers the cut tea leaves A toward a predetermined position. Here, the transfer apparatus 5 relays and transfers the tea leaves A from the reaping machine body 3 to the storage unit 4. Specifically, a mode is adopted in which the tea leaf A immediately after cutting is directed upwardly to the accommodation unit 4 and directly above the cutting blade 31. Here, the transfer of the tea leaves A is an air flow, that is, the pressure wind W is sent into the duct and transferred to the accommodating portion 4, and here, due to the use of a plurality of duct members, these are referred to as the duct unit 5A. Collectively.

As shown in FIGS. 1 to 3, the duct unit 5 </ b> A includes a transfer duct 6 and a blower duct 7 as main members. Among these, the transfer duct 6 is formed so as to face the upper part of the housing part 4 after being raised almost straight from the upper part of the cutting blade 31.
Further, the blower duct 7 feeds the pressure air W from the rear side of the cutting blade 31, that is, the rear side of the cutting blade 31 that is rearward with respect to the plucking direction, and generates the conveying wind W <b> 1 that becomes an upward flow in the transfer duct 6. It is something to be made. Hereinafter, the transfer duct 6 and the air duct 7 will be described in more detail.

First, the transfer duct 6 will be described. As shown in FIGS. 3, 4, and 5, this is set up almost directly above the cutting blade 31, and transfers the tea leaves A immediately after cutting to the storage unit 4. Here, a part (lower part) where the transfer of tea leaves A is started in the transfer duct 6 is a transfer start part 62, and a part (upper part) where the transfer of tea leaves A is finished is a transfer end part 63.
In this embodiment, the transfer start portion 62 is opened to the lower side and is formed so as to surround the cutting blade 31 in a plan view.
Further, as shown in FIGS. 4A and 4C, for example, the transfer duct 6 is configured in a single tubular shape in which the transfer pipe does not branch in the middle, and further has a constricted shape in the width direction from below to above. It is set as the shape which has the shoulder part 61 made.

An extension duct 6A is attached to the upper part of the transfer duct 6 and is appropriately curved so that the discharge port 64 formed in the extension duct 6A faces the accommodating portion 4. Incidentally, in this case, the discharge port 64 substantially becomes the transfer terminal portion 63.
In addition, it is preferable that the transfer duct 6 does not change a width dimension, a cross-sectional area, etc. abruptly in the middle of the transfer from the transfer start part 62 to the discharge port 64 (transfer terminal part 63), and this is the damage of the tea leaf A accompanying transfer. Is to reduce as much as possible.
The transfer duct 6 and the extension duct 6 </ b> A may be configured so that at least a part thereof is nested or flexible and can move up and down together with the cutting blade 31.

Here, as described above, the transfer duct 6 is configured as a single tube in which the transfer pipe does not branch in the middle, and the cross-sectional shape thereof is the front and rear front plates 6F and the rear plate that are long in the width direction of the cutting blade 31. 6R and both side plates 6S connecting them have a flat cross-sectional shape, and a transparent window is provided on the front plate 6F and the rear plate 6R. This see-through window is composed of a front see-through window 66 provided on the front plate 6F and a rear see-through window 67 provided on the rear plate 6R, and either or both of the front see-through window 66 and the rear see-through window 67 are upper and lower. It is configured as a combination of a plurality of windows divided in the direction. For this reason, the remarkable strength reduction of the front plate 6F and the rear plate 6R due to the formation of the transparent window can be avoided. In particular, when the front plate 6F and the rear plate 6R are bent, it is possible to easily form and install the transparent material constituting the transparent window by suppressing the size of the transparent window having the bent portion. It becomes.
Specifically, as shown in FIGS. 3 and 4, for example, the front see-through window 66 and the rear see-through window 67 are each composed of a combination of a plurality of single windows, and the transfer duct 6 is erected. In this state, the front see-through window 66 and the rear see-through window 67 are formed by shifting the formation positions in the height direction in steps.

  The front see-through window 66 and the rear see-through window 67 are configured by closing notches formed by notching the front plate 6F and the rear plate 6R with a transparent material such as vinyl, acrylic, plastic, glass or the like. In this embodiment, as an example, a transparent vinyl chloride sheet is stretched from the outside.

Furthermore, it is preferable that the range that can be viewed from the front side through the front see-through window 66 on the inner surface of the rear plate 6R in the transfer duct 6 is colored in an odd color.
Here, the abnormal color means a color exhibiting a color tone different from that which enters the field of view through the front fluoroscopic window 66 when the worker who rides on the teacup straddle-type plucking machine 1 faces backward. As an example, a color tone different from the color (branch: brownish brown, leaf: green) and the background color (sky: blue, gray cloud: white, gray tea tree: green) is selected. In this embodiment, yellow is adopted as an example.

  In addition, when the transfer duct 6 constituted by the front plate 6F, the rear plate 6R, and both side plates 6S connecting them can be constituted by a transparent resin material having a sufficient strength, the entire area of the front plate 6F is covered. As the front see-through window 66, the entire rear plate 6 </ b> R can function as the rear see-through window 67.

  As described above, in this embodiment, the tea leaves A are not transported to the rear side of the cutting blade when the tea leaves A are transported upward, so that the front and rear lengths of the transport device 5 and thus the reaper body 3 can be shortened. In addition, when the reaping machine body 3 is viewed from the side, a flow relay duct 7B, which will be described later, is provided so as to substantially overlap the transfer duct 6, which also reduces the thickness dimension of the duct unit 5A (transfer device 5). This contributes to shortening the longitudinal length of the reaping machine body 3.

Next, the air duct 7 will be described. This comprises a flat distribution rear duct 7A provided so as to overlap the rear surface of the transfer duct 6, and a diversion relay duct 7B for supplying the pressure air W to the distribution rear duct 7A. is there.
First, as shown in FIG. 4 (c), the distribution rear duct 7A is formed in a tapered shape from the connection position (left side) to the opposite relay duct 7B in the rear view toward the opposite side (right side). Yes. That is, the lower part of the distribution rear duct 7A has a shape adapted to this portion in order to diffuse and distribute the pressure wind W in the width direction over the entire transfer start portion 62 in the transfer duct 6, and has a substantially triangular shape with this portion as the base. It is formed.
Such a distribution rear duct 7A fixes the two plate members 71, 72 so as to maintain a predetermined distance by the support column 73, thereby making the space between the plate members 71, 72 a passage for the pressure air W. is there.
Further, the lower portion of the distribution rear duct 7A is bent forward as shown in FIGS. 3 and 5, and a blowout port 74 is provided for diffusing and distributing the pressure air W over the entire transfer start portion 62 in the transfer duct 6 in a side view. It is formed upward.
On the other hand, an air supply port 76 for the pressure air W is formed on the short side of the distribution rear duct 7A having a substantially triangular shape when viewed from the rear.

Further, a rectifying plate 75 is disposed in the space between the plate members 71, 72, and the rectifying plate 75 substantially receives the pressure air W taken from the air supply port 76 in the width direction of the cutting blade 31. It is a member for flowing uniformly, and has an appropriate shape according to the place where it is disposed.
Specifically, as shown in FIG. 4C and FIG. 5 as an example, a plurality of brackets having an L-shaped cross section are used (in this example, about twenty), and this is blown in front view. Attached at appropriate intervals along the width direction of the outlet 74. And even if the pressure wind W is taken in from the air supply port 76 provided at the biased position by the rectifying plate 75, it is guided almost uniformly in the width direction of the cutting blade 31, and has the same strength over the entire width of the cutting blade 31. This can be converted into the transport air W1.

  Next, as shown in FIG. 3, the diversion relay duct 7 </ b> B is configured to have a constricted rectangular tube shape, and an inlet for connecting a blower hose 28 </ b> A to which a flexible duct is applied. 77 and a discharge port 78 is formed on one side of the square tube.

And the ventilation duct 7 is comprised by integrating these two members so that the air supply port 76 in the distribution back surface duct 7A and the discharge port 78 in the diversion relay duct 7B may be connected.
Further, the air duct 7 and the transfer duct 6 are integrated, and the front surface of the air duct 7 and the back surface of the transfer duct 6 are brought into close contact with each other, and the air outlet in the air duct 7 as shown in FIG. 74 faces the transfer start part 62 in the transfer duct 6.
In this assembled state, the diversion relay duct 7B is disposed in the vicinity of the shoulder 61 along the side surface of the transfer duct 6 as shown in FIGS. It is provided in a state where it does not overhang in the width direction.
As described above, in this embodiment, only one diversion relay duct 7B is provided, and one distribution back duct 7A can supply the pressure air W over the entire width of the transfer duct 6.

  The transfer device 5 of the present invention and the teacup-climbing type plucking machine 1 as an example of a reaping device to which the transfer device 5 is applied have the above-described basic structure as an example. explain.

(1) Formation of Conveyance Air First, in order to generate the conveyance air W <b> 1 in the transfer duct 6, the prime mover 26 is driven and the pressure air W is generated by the blower 27. The generated pressure air W is then led from the introduction port 77 through the air duct 28 (the air hose 28A) into the airflow relay duct 7B, where the flow velocity increases due to the shape of the constricted square tube. In this state, the air is taken into the distribution rear duct 7A through the discharge port 78 and the air supply port 76.

The pressure air W introduced into the distribution rear duct 7A moves while diffusing from the air supply port 76 toward the air outlet 74, as shown in FIG. Generation | occurrence | production is prevented, and it distributes and distributes substantially uniformly over the width direction of the blower outlet 74, and the flow direction is adjusted to a direct downward direction.
Next, the pressure air W blown upward from the blower outlet 74 at the rear of the cutting blade 31 enters the transfer duct 6 from the transfer start portion 62 and rises in the transfer duct 6 as the transport air W1.
As shown in FIG. 5, the transport air W <b> 1 is an upward flow that is directed almost directly upward from the rear of the cutting blade 31, and transports at least transporting the tea leaves A to the discharge port 64 (transfer terminal portion 63) of the transport duct 6. Have the ability.

(2) Transfer Mode of Tea Leaves The tea leaves A are attracted to the rear side of the cutting blade 31 immediately after cutting by such a conveying wind W1. This is because a negative pressure is formed in the vicinity of the rear of the cutting blade 31, specifically, in the vicinity of the blowout port 74, by blowing the pressure air W (conveyance air W <b> 1) from the rear of the cutting blade 31. It is considered that the portion is drawn toward the outlet 74 side.
Then, the tea leaves A attracted to the air outlet 74 are then lifted in the transfer duct 6 on the transport air W1 that forms the upward flow, and enter the tea bag B provided in the accommodating portion 4 from the discharge port 64. It is sent and accommodated here.

At this time, the worker who has boarded the teacup straddle-type plucking machine 1 turns the tea leaves A in the transfer duct 6 by looking backwards directly or indirectly by the rearview mirror M. Or the rear side of the teacup straddle-type plucking machine 1 can be confirmed.
Specifically, since the front see-through window 66 and the rear see-through window 67 are formed by shifting the formation positions in the height direction in steps, both the front see-through window 66 and the rear see-through window 67 are changed depending on the viewing angle. It is possible to select either a field of view that passes through the front view window 66 or a field of view that passes through only the front see-through window 66 and is blocked by the inner wall (rear plate 6R) of the transfer duct 6.
As a result, when a field of view that passes through both the front see-through window 66 and the rear see-through window 67 is selected, the inside of the accommodating portion 4 located behind the transfer duct 6 and the back thereof can be seen.

  On the other hand, when a field of view that passes only through the front see-through window 66 and is blocked by the inner wall of the transfer duct 6, that is, the inner surface of the rear plate 6R, is selected, the cutting branch leaf A that is being transferred through the transfer duct 6 is selected. The behavior and the like can be clearly visually confirmed without the cut leaves A being buried in a teacup or the like as a background.
