Description

[Detailed description of the invention] Generally, in field work using a combine harvester equipped with a waste straw binding machine, the bundled waste straw is left in the field in a horizontal position.

Therefore, if things continue as they are, the bundled straw will be exposed to the sun.
Since it is difficult to completely dry the straw naturally by ventilation, conventionally, if dried waste straw was to be obtained, some kind of additional drying operation was required.

In view of the above points, the purpose of the present invention is to allow the bundled waste straw to be properly naturally dried while being left in the field. The purpose of this is to ensure that the culm stands upright in the field regardless of changes in its condition, such as short culms.

The bundling and waste straw discharging device of the present invention, which solves the above-mentioned problems, is a bundling and waste straw discharger that takes over the bundled waste from the waste straw tying machine and transports it to an appropriate height position above the field. A straw conveying device is provided, and the bundled waste straw that is dropped and released from the transport end of the bundled and removed straw transport device is guided vertically in the vicinity of the transport end of the bundled and removed straw transport device in an upright position. A bundled waste straw falling guide body having a horizontal cross section that is approximately U-shaped and opened in the direction opposite to the direction of transport of the bundled waste straw is provided, and furthermore, a bundled waste straw conveying device and a bundled waste straw guide body are provided. The present invention is characterized by being provided with a mounting angle changing device that allows the relative angle to be changed.

Next, one embodiment will be explained with reference to a figure. In the figure, 1 is a waste straw tying machine attached to the rear part of a combine harvester 2. A straw draining passage 3 is formed which connects and slopes rearward and downward, and above the terminal end of the straw scraping passage 3, a joint part 4 equipped with a bill holder and a discharge arm 5 are disposed, and a dump car is placed below it. 6 and a needle 7 are disposed, and the waste straw supplied from the combine 2 to the starting end of the waste straw passage 3 in a horizontal position with its base facing the uncut land is discharged by the action of the packer 6. When a certain amount of waste straw is collected at the end of the straw passage 3, it is tied by the needle 7 and at a part near the tip of the straw by the action of the knot 4, and then tied. The structure is similar to that of a conventional one so that the waste straw is discharged rearward by the action of the discharge arm 5.

Reference numeral 8 denotes a bundled waste straw discharging device according to the present invention, which is installed at the rear of the waste straw binding machine 1. The configuration of the bundled waste straw discharging device 8 in this embodiment will be explained below.

That is, it is stretched in an inclined manner from the vicinity of the knotting action site at the end of the straw passageway 3 toward the upper rear and away from the uncut land (to the right in FIG. 3), and the power is transmitted from the straw binding machine 1. A conveying endless belt 9 that is driven to rotate in the direction of the arrow, a pincher body 10 that is disposed opposite to the conveying route of the endless belt 9, and a clamping body 10 that is disposed on the uncut land side of the endless conveying belt 9. A bundling and removing straw conveying device 12 consisting of a stock guide rod 11 that is sequentially inclined downward with respect to the conveyance path of the endless strip 9 is attached to the rear of the straw binding machine 1 through an appropriate attachment means. There is. In addition, the clamping body 10 is composed of a plurality of links connected in series so that the bundled waste straw having a large diameter can be continuously and satisfactorily clamped between it and the endless transport belt 9. .

Therefore, according to this bundled waste straw transport device 12, the bundled waste straw discharged from the waste straw binding machine 1 is delivered to the starting end of the transport device 12, and the tip portion near the bundled portion is transferred to the endless belt 9. The stock is conveyed rearward and upward while being held between the stock and the pinching body 10. During this time, the tip of the stock is held and the stock is slightly rotated due to the frictional resistance of the pinching body 10. The portion is spread out into a conical shape, and further, by the action of the stock head guide rod 11, the stock base portion is delayed in the conveyance direction and is caused to change its posture downward. Then, the bundled straw is carried out by the conveying device 1.
2 is released from the end, but at this time, the base part of the stock is in an upright position along the vertical direction where it is spread out in a conical shape.

Furthermore, in the vicinity of the conveyance end of the bundled and removed straw conveying device 12 configured as described above, a bundled and removed straw falling guide 13 is configured with a substantially U-shaped plate having an appropriate height. It is attached to the machine frame of the bundled and removed straw conveying device 12 in a substantially vertical position so as to surround the transport end portion of the bundled and removed straw conveying device 12 from behind. That is, its upper end is rotatably pivoted 15 to a support rod 14 fixed to the machine frame of the bundled and removed straw transport device 12, and its lower end is supported by the bundled and removed straw transport device 12 via the attachment angle changing device 20. has been done.

The attachment angle changing device 20 includes a fan plate 1 that is rotatable on the machine frame of the binding and conveying device 12 by a pivot shaft 16a.
The cylindrical body 17 is fixed to a part of the fan plate 16b whose mounting angle can be changed by screwing the bolt 16d, which is passed through one of the holes 16c on the periphery of the cylinder 6b, into the machine frame. By selecting the penetration position of the hole 16c of the fan plate 16b of the bolt 16d with respect to the frame, one end is tied to the cylinder 17 which is rotatably fixed to the machine frame, and the lower end of the fall guide 13 is pivoted 18a. The supporting rod 18 is inserted into the supporting rod 18 and can be fixed to the cylindrical body 17 by screwing a bolt 19, so that the attitude of the bundled waste falling guide 13 can be changed and adjusted.

By positioning the terminal end of the bundled and removed straw conveying device 12 at an appropriate height above the cut surface and by setting the height of the falling guide body 13 appropriately, the falling straw can be guided. Lower end 13 of body 13
A is spaced apart from the cut ground by a distance slightly longer than the length of the bundled waste straw.

In the figure, reference numeral 22 denotes a waste straw separating device comprising a separating claw 21 that can travel across the waste straw passage 3 intermittently in synchronization with the activation timing of the knotting section 4. The separating claws 21 reliably separate the collected waste straw that is being collected and the waste straw that is likely to become entangled with it and will be bundled next time, so that the bundling and release functions of the waste straw are always performed well. It is a diagram.

Next, the operation will be explained with respect to the above embodiment.
Now, when the combine harvester 2 is used to perform field work, the tips of the bundled waste straw discharged from the waste straw binding machine 1 are transferred to the starting end of the bundled waste straw conveying device 12, and are carried upward and backward. The plant is conveyed, and by the pinching and conveying action of the endless transport belt 9 and the pinching body 10, and the action of the stock head guide rod 11, the stock base portion is spread out into a conical shape and placed in an upright position along a substantially vertical direction, and The bundled waste straw is dropped from the transport end of the bundled waste transport device 12 with its base facing downward.

At this time, the bundled waste straw falling from the bundled waste straw transporting device 12 is formed into a substantially U-shape that can surround the terminal end of the transporting device 12, that is, it can surround the bundled waste straw from the direction opposite to the transport direction. The vertical drop guide 13 guides the transport device 12 so that it falls vertically, regardless of the impact caused when it is released from the end, so it is always maintained in an upright position. The plant is allowed to fall onto the mowed field, and is therefore reliably erected onto the mowed field with the base portion spread out in a conical shape.

The lower end 13a of the guide 13 is located above the bundled straw standing on the already cut ground, so that as the combine 2 advances, the bundled straw that stands is guided to the tip of the guide 1.
There is no risk of 3 intervening and knocking it down.

In this way, the bundled waste straw is successively erected in the field in a conical and diffused posture, so that the natural drying of the bundled waste straw is performed extremely well.

Further, in the above embodiment, the falling guide body 13
Although it is installed in an almost vertical position, it can be tilted to an appropriate angle by adjusting the installation angle changing device 20, and can be set up on the already mown field according to the attitude of the bundle of straw taken over from the bundled and removed straw conveying device 12. The dropping guide 13 guides the waste bundles to the most suitable posture for dropping the waste bundles, and adjusts the angle to an angle suitable for changing the posture.

In the illustrated mounting angle changing device 20, the bolt 19 is loosened to allow the support rod 18 to slide freely relative to the cylinder 17, the bolt 16d is removed, and the fan plate 16b is rotated to form the desired hole 16c. Align the bolt 16d with the screw hole (not shown) on the machine frame.
The cylinder body 17 and the support rod 18 are fixed by tightening the bolts 19, and the drop guide body 13 is fixed at a desired relative angle to the transport device 12, and the posture of the drop guide body 13 and the bundle removal are fixed. The position of the straw conveying device 12 relative to the end is changed and adjusted.

The above-mentioned changes and adjustments are made appropriately so as to provide the most suitable fall guiding action for standing the bundled straw upright on the already-cut land, depending on various conditions such as the size of the bundle of straw.The same adjustments are made even if the bundled straw conveying device 12 is configured so that the conveying end position can be changed and adjusted depending on the length of the bundled straw.By changing the position of the fall guiding body 13 in this way, a guiding action can be performed that always allows the bundled straw to fall vertically under any conditions.

In the above-mentioned embodiment, the bundling and waste straw discharge device 8 is a waste straw tying machine 1 which is attached to the rear of the combine harvester 2 and is capable of tying the waste straw in a horizontal position with the stem facing toward the uncut field. Although an example is shown in which the device is attached to a combine harvester with a straw tying machine, the bundling and waste straw discharging device according to the present invention can be used in addition to the type of combine with a straw tying machine as described above, in which a straw tying machine is attached to the side of the combine. Any type of straw binding machine that is constructed so that it can bind straw in an upright position along the vertical direction or in a horizontal position with the tips facing the uncut field. This device can be installed on a combine harvester with a waste straw tying machine.

In addition, in the above embodiment, an example was shown in which the bundled and removed straw conveying device 12, that is, the endless conveying belt 9 was stretched upwardly in an inclined manner. It is set as appropriate depending on the type of combine harvester with a waste straw binding machine to which the waste straw discharge device 8 is installed. Furthermore, at the end of the conveyance of the bundled and removed straw conveying device 12, the bundled and removed straw is configured to be in an upright position along the substantially vertical direction by the action of the stock guide rod 11; Even if it is not specified, it is not necessary to provide the stock guide rod 11 because the falling guide member 13 can guide the fall of the bundled waste straw so that it stands up on the field. .

Furthermore, in the above embodiment, the bundled waste straw falling guide 13 is constituted by a substantially U-shaped plate whose horizontal cross-sectional shape is open in the direction opposite to the conveyance direction of the bundled waste straw. Although an example is shown in which it is attached to the machine frame of the waste straw conveying device 12 via the support rods 14, 18, etc., the shape and configuration of the falling guide body 13 and the attachment means can be changed within the range that can be easily conceived by a person skilled in the art. Optional.

As is clear from the above description, the bundled waste straw discharge device of the present invention transports the bundled waste straw discharged from the combine harvester with the waste straw binding machine to an appropriate height position above the field using the bundled waste straw conveying device. In addition, the bundled waste straw is configured to fall in an upright position along the vertical direction by the action of the bundled waste straw falling guide, so that the bundled waste straw can be left standing in the field.

In addition, we have installed a mounting angle changing device that allows you to change the relative angle between the bundled waste straw falling guide and the bundled waste straw transport device, so it can be changed depending on the various conditions of the waste straw such as the size of the waste straw bundle, long culm or short culm, etc. In response to changes in the posture of the waste straw bundle at the end of the bundled waste straw conveying device due to etc., and changes in the height of the lower end of the waste straw from the field surface,
The posture of the bundled waste straw falling guide body can be changed to an angle of inclination that provides the most suitable fall guiding action for making the bundled waste straw stand upright on the cut field.

Therefore, according to the device of the present invention, the bundled waste straw can always be made to stand upright in the field, and even when left in the field, it can be air-dried well, and there is no need for separate drying work as in the past, making it efficient. It is possible to obtain long straw that is well dried and has great commercial value.
