Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lifting mechanism for a reaping machine, and more specifically, the invention relates to a lifting mechanism for a reaping machine. The present invention relates to an improvement in a pulling mechanism for a reaper in which a lateral feed path for the stem culm is formed so that the stem culm is sent in a direction substantially orthogonal to the pulling device.

[Conventional technology]

Conventionally, as a reaping machine in which a feed path for the stem culm is formed as mentioned above, there is one that is configured with a binder, as shown in Japanese Utility Model Application Publication No. 59-156438, for example. Smoothly sends the stem culm raised by the device to the horizontal feeding path, and
In order to reduce the effect of the undulating claws on the grain-bearing parts of short rice plants, etc., a guide member whose guide posture can be adjusted is provided.

[Problem that the invention attempts to solve]

However, the binder cited in the reference has a structure in which the timing at which the stem culm lifts up and separates from the claws is adjusted simply by changing the posture of the guide member, so for example, when harvesting short rice, etc. At the same time that the grain part is lifted by contact with the undulating claw, the grain part on which this lifting force is applied is pushed outward by contact with the guide member. There is room for improvement because grains may fall off because they are temporarily caught between the guide members.

The purpose of this invention is to make reasonable improvements that will prevent grains from shedding even when harvesting short rice, etc.
Another object of the present invention is to obtain a configuration that allows the stem culm to be well guided along the transverse feed path.

[Means for solving problems]

The feature of the present invention is that a guide member for extruding the stem culm is provided at the top of the lifting device, which is made up of a number of circularly driven undulating claws housed in a case, and whose upper end can be displaced in a direction that overlaps with the lifting path. At the same time, the lifting device is provided with an adjustment mechanism for changing the length of the lifting path by displacing the terminal end position of the raising rail of the undulating claw in a direction along the lifting path, and displacing the guide member toward the lifting path. The guide slope and the adjustment mechanism are interlocked and connected in such a state that the larger the amount, the shorter the length of the pulling path.The operation and effect thereof are as follows.

[Effect]

If the above characteristics are configured as shown in FIGS. 1 and 2, A, B, and C, when the posture of the guide member 9 is changed, the guide hole 9b formed in the guide member 9 and the case 1c of the lifting device 1 are connected. Guide hole 1h formed
In order to lift up the guide pin 14 that is inserted through the guide pin 14 and displace it along the path A, the end position of the erecting rail 13 of the undulating claw 1b is changed by moving the slide rail 13a to which the guide pin 14 is attached. Become.

The more the guide member 9 protrudes toward the raising path A, the more the end position of the raising path of the undulating claws 1b is displaced toward the upper side in the lifting direction, and the position where the undulating claw 1b is set to the free position becomes the position of the lifting claw 1b. upper side in the direction (first
(lower side in the figure) and guide member 9 and undulating claw 1b.
This can reduce the chance of the stem culm getting caught between the two.

The adjustment mechanism C consists of a slide rail 13a, a guide pin 14, and a guide hole 1h, and by inserting the guide pin 14 into the guide hole 9b formed in the guide member 9, the adjustment mechanism C and the guide member 9 can be interlocked. structure is constructed.

[Effect of idea]

Therefore, by interlocking and connecting the guide member and the adjustment mechanism, even when harvesting short rice, for example, by simply displacing the guide member,
A structure was obtained in which the strong force exerted by the undulating claws was reduced on the granulation part, and the stem culm was guided to the transverse feed path in a state where granulation was less likely to occur.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figure 5, a pair of left and right pulling devices 1, 1 that pull up the planted stem culm, a clipper-type reaping device 2 that cuts the base of the stem culm, and a clipper-type reaping device 2 that cuts the stem culm in the lateral direction of the machine body. A lateral conveyance device 3 is provided at the front of the traveling body 5, and a binding device 4 for tying the stem culms sent by the lateral conveyance device 3 and discharging them outward from the side of the body 5 is provided.
A traveling body 5 is equipped with traveling wheels 6, an engine 7, and a control handle 8, and constitutes a binder as an example of a reaper.

As shown in FIG. 4, the left and right lifting devices 1, 1 each have a large number of undulating claws 1b attached to an endless chain 1a housed in a case 1c, and lift these undulating claws 1b. A drive system (not shown) is provided on the path A side to set the robot in an upright position and drive the robot in circulation.

Further, a lateral feeding path B is formed for sending the stem culms sent through the lifting paths A and A to the binding device 4 by the conveying force of the lateral feeding device 3, and this lateral feeding path B
A plate-shaped guide member 9 is attached to the left-hand lifting device 1 in order to guide the stem culm from the lifting path A on the left side of the machine and to reduce shedding of short rice grains. .

That is, as shown in FIGS. 2A, 2B, and 4A to 4, a guide member 9 whose posture can be changed in a direction overlapping with the lifting path A is provided at the upper part of the case 1c of the left-hand lifting device 1. is attached to the case 1c so as to be swingable via the support shaft 10, and a circular arc-shaped elongated hole 9a is provided in the guide member 9 in order to fix the swinging posture. 11 is provided with a bolt 12 that is screwed into the bolt 11.

Further, the lifting device 1 is provided with a rail 13 for raising the raising claws 1b.
The erecting rail 13 is equipped with a slide rail 13a for raising and changing the end position of the case 1c along the raising route A.
A guide pin 14 is attached that passes through h.

Further, the guide pin 14 is attached to the guide member 9 so that the guide member 9 is pulled up and set in a position farthest from the path A, and the guide pin 14 is connected in such a manner that the raising rail 13 is in a long state. The posture of the guide hole 9b to be inserted is set.

When harvesting short rice, etc., the guide member 9 is pulled up and swung toward the path A, so that the undulating claws 1b are set in a free state near the end of the pulling path A. moves forward, and the stem culm is guided to the lateral feed path B by the pushing action of the guide member 9 without any strong force acting on the stem culm from the undulating claws 1b.

As shown in FIGS. 5 and 6, there are weeding tools 5 on the left and right and in the center in front of the left and right pulling devices 1, 1.
..., and a sled body 16 having vertical walls 16a formed on both sides is attached extending from the weeding tool 5 on the right side to substantially below the binding device 4.

[Another example]

In addition to the above-mentioned embodiments, the present invention allows the guide member to have a structure in which the guide edge is formed by smoothly bending the material, and also includes an adjustment mechanism for changing the length of the raising path on the upright rail. It is also possible to construct a structure in which the terminal end swings in a direction away from the lifting path.
