Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention automatically cuts a tobacco trunk, and a worker only needs a little labor, and the rest is automatically a work vehicle. The present invention relates to a tobacco trunk harvesting car that can be loaded into and taken out of the ridge.

(Prior art) Conventionally, when cutting and harvesting tobacco trunks, the trunks are cut with a sickle or saw, lined up in ridges, and when the cutting work is finished, the trunks are collected and loaded on a trailer or the like until the drying room. It was common to carry.

However, this is extremely inefficient and hard work,
Especially in the work of cutting the trunk, it is necessary for the worker to hold the trunk, make a middle waist, and arrange it in the cutting ridges with a sickle etc. Since they will be collected and carried, it is very easy to get tired.

As a means for automating the cutting of the tobacco trunk during the above-mentioned work, there is a "tobacco trunk cutting device" of Japanese Patent Publication No. 61-10083.
Also, Japanese Patent Application Laid-Open No. 62-104510 proposes a "leaf tobacco mowing machine and a leaf tobacco mowing method", but these are simply used in such a manner that the tobacco is left in the state of being mowed in the ridge,
Since several cigarettes are placed between the ridges, no consideration is given to carrying out a heavy and bulky tobacco trunk outside the ridges.

On the other hand, as a working machine that incorporates the function of carrying out to the outside of the ridge,
There are Japanese Examined Patent Publication No. 51-31727 "Tobacco Trunk Harvester", and Japanese Examined Patent Publication No. 52-847 "Tobacco Trunk Harvester", but in these, the trunk is placed in the tobacco trunk storage place (packing platform) on the working machine, It is the workers who load it, and they are not freed from the heavy labor of manually stacking the trunks that are being mowed one after another.

As described above, there is currently no means provided for consistently efficient and light labor for cutting tobacco stems, loading them on working machines, and carrying them out of the ridges.

(Problems to be Solved by the Invention) The present invention is intended to solve such problems found in the prior art, and a cigarette trunk that has been automatically cut by a single vehicle body The objective is to provide a tobacco trunk harvesting vehicle that can automatically perform loading and unloading with high efficiency by merely interposing light work (device for transferring the trunk to the conveyor).

An embodiment corresponding to claims 1, 6, and 7 in the drawings, an embodiment corresponding to claims 2, 6, and 7 in FIG. 3, and an embodiment corresponding to FIG. The third term, the fifth term,
Embodiments corresponding to items 6 and 7 are shown respectively.

First, in FIG. 1, reference numeral 1 is a self-propelled truck that straddles a ridge, and a link type hydraulic lifting device 21 having an upper portion formed on a trunk loading platform 22 is provided on a loading platform 4, and an automatic trunk harvesting device is provided in the center of a front portion thereof. 2 is provided.

The mode of this automatic trunk harvesting device 2 is not particularly limited, but for example, the rotary cutting saw blade 2 as in Japanese Patent Publication No. 61-10083 mentioned above.
A "tobacco trunk cutting device" or the like having a and a hanging groove cutting blade 2b is desirable.

The self-propelled carriage 1 is attached to one side of the automatic trunk harvesting device 2 to provide a platform 3 for a working vehicle.
The operator who rides on the can catch the tobacco trunk cut by the automatic trunk cutting device 2 by hand before it falls yet.

Then, on the loading platform 4 of the self-propelled carriage 1 and within the reach of the operator of the boarding platform 3, vertical transport conveyors 6 equipped with trunk mounting frames 5 at predetermined intervals in the rotation direction are provided in two left and right articles, The mowing trunk on the trunk mounting frame 5 is made to fall from the upper rotary folded end of the vertical conveyor 6.

Then, a horizontal transport conveyor 7 of a predetermined length is provided toward the rear of the loading platform 4 from directly below the upper rotary folding end of the vertical transport conveyor 6, and the cutting trunk is dropped from the rear rotary folding end of the horizontal transport conveyor 7. In addition, the horizontal conveyor 7 allows the driven base shaft 8 to which the driven wheel 9 on the rear side is pivoted to reciprocate along the horizontal guide shaft 10 and the drive shaft 11 to which the front drive wheel 12 is fixed. An adjusting base shaft 13 having a movement adjusting wheel 14 pivotally attached to the bottom of the adjusting base shaft 13, and a piston head 19 of a hydraulic cylinder 18 on the adjusting base shaft 13.
By reciprocating along the vertical guide shaft 15, and a belt 16 is hung between the driven wheel 9, the intermediate drive wheel 12, and the movement adjusting wheel 14, While slowly expanding and contracting the horizontal portion, the cutting trunk is dropped and loaded from the rear side turning back end on the trunk loading platform 22 of the link type hydraulic lifting device 21 on the loading platform 4 at a uniform height.

In the drawing, 23 is a tension pulley facing the lower middle of the belt 16, and 24 is the driven base shaft 8 of the horizontal conveyor 7.
Weight, 25, 27 for smooth extension of the rear of the
Is a control panel, 26 and 28 are control rods, 29 is a conduction box, and M is a prime mover for driving each mechanism.

Next, referring to FIG. 2, among the embodiments shown in FIG.
A mode in which the horizontal conveyor 7 and the mechanism associated therewith are removed is shown. That is, in terms of action, the tobacco stem is
Directly from the upper turning end of the vertical conveyor 6 to the loading platform 4
It is dropped and loaded on the trunk loading platform 22 of the upper link type hydraulic lifting device 21. Therefore, in this case, it is necessary for the worker to manually level the fallen trunk evenly by manual work.

Next, in FIG. 3, similar to the embodiment of FIG.
Although the horizontal transfer conveyor 7 is provided, the length of the horizontal transfer conveyor 7 is constant, and in particular, the expansion / contraction means of the horizontal portion is not provided. That is, in terms of action, the tobacco stem is
The loading platform 4 is provided from the rear rotary folding end of the horizontal conveyor 7.
It is dropped and loaded on the trunk loading platform 22 of the upper link type hydraulic lifting device 21. In this case, since the tobacco trunk falls in the middle of the trunk loading table 22, the loaded trunk naturally slides down like a mountain, and the leveling work is reduced by the hand of the operator.

Next, in FIG. 4, the vertical transport conveyor 6 and the horizontal transport conveyor 7 are combined in the same manner as the embodiment of FIG. The reciprocating motion of the adjusting base end 13 along the guide shaft 15 (therefore, the reciprocating motion of the driven base shaft 8 along the horizontal guide shaft 10) is performed by the outer end 8a of the driven base shaft 8 horizontally reciprocating and the reciprocating motion of the adjusting base shaft 13 vertically reciprocating. The end 13a and the end 13a are respectively connected to the endless chain conveyor 20, and the endless chain conveyor 20 is rotated in a forward or reverse direction at a predetermined stroke so as to be synchronously performed.

In this case, the embodiment of FIG.
There is no difference in operation, only the activation means for expansion and contraction of.

(Operation) Now, the operation will be described based on the mode of FIG. 1. First, when an operator stands on the boarding platform 3 and the self-propelled vehicle 1 travels across a frog, a control panel 25 provided at a rear portion of the control panel 25 is provided. Each of the control rods 26 and each of the control rods 28 of the control panel 27 provided on the boarding platform 3 are operated to raise the trunk loading platform 22 of the link type hydraulic lifting device 21 on the loading platform 4, and the automatic trunk harvesting device 2 ( The rotary cutting saw blade 2a and the hanging groove cutting blade 2b) are driven, and the vertical conveyor 6 and the horizontal conveyor 7 are driven,
Further, the hydraulic cylinder 18 is operated to slowly and vertically reciprocate the adjustment base shaft 13 connected to the piston head 19, whereby the horizontal portion of the belt 16 is slowly expanded and contracted. (Fig. 5A).

Now, in this state, when the forward running is started, the grown tobacco stems are sequentially mowed by the rotary cutting saw blade 2a of the automatic trunk mowing device 2 leaving the trunk part at the same time, and at the same time, by the groove cutting blades 2b, the tobacco stems are cut off at the base of the cutting trunk. Hooking grooves are formed for hanging upside down as a drying step (Fig. 5B).

Then, at the time of harvesting the trunk, the worker of the boarding platform 3 grasps the trunk of the trunk by hand and puts it on the trunk mounting frame 5 of the vertical transport conveyor 7 one by one (FIG. 5C).

Then, the trunk mounting frame 5 rises along the guide frame 17, and the mowing trunks on the trunk mounting frame 5 sequentially drop on the belt 16 of the horizontal transport conveyor 7 from the upper rotary folding end of the conveyor 7, and the rear side thereof. Although it falls on the trunk loading platform 22 of the link type hydraulic lifting / lowering device 21 on the loading platform 4 from the turning back end, the horizontal portion of the band 16 slowly expands and contracts, so that the rearward rotation is always performed. The position of the folded end moves, and the falling trunks are loaded on the trunk loading platform 22 at a uniform height.
(Fig. 5, D and E).

During this period, the link type hydraulic lifting / lowering device 21 is lowered in accordance with the progress of stacking of the trunk so as to maintain an appropriate fall distance of the trunk (to FIG. 5).

Thus, when the trunk is fully loaded, the self-propelled carriage 1 is moved to the outside of the ridge and carried out (Fig. 5G).

It should be noted that the operation of the embodiment shown in FIG. 4 is exactly the same as that of the embodiment shown in FIG. 1 and the difference between the operations shown in FIGS. 2 and 3 is as described above.

[Advantages of the Invention] The present invention is as described above, and is a self-propelled carriage 1 traveling across a ridge.
With the automatic trunk harvesting device 2 installed in the front part of the car, a tobacco kerf is cut and a kerf for hanging is formed at the same time, and one worker on the boarding platform catches the sown trunk by hand. ,
If this is supplied to the vertical transfer conveyor 6, then the load carrier 4 can be passed through the horizontal transfer conveyor 7 or without it.
Or dropped to the trunk loading platform 22 of the link type hydraulic lifting device 21,
Since they are loaded, only light work is added, and the rest can be harvested automatically and with high efficiency.

In particular, in the embodiment of FIG. 1 and FIG. 4 in which the horizontal conveyor 7 expands and contracts, it is possible to naturally load it evenly on the trunk loading table 22, so that further labor saving can be achieved from this point as well. .
