Description

Detailed Description of the Invention The unexploded IJ4 is equipped with a device that changes the driving speed of the handling cylinder between a low-speed state for loading and a high-speed state for regular use, and also changes the swinging sorting plate for processed material between a conventional sorting state and a necessary sorting state. This invention relates to a threshing device equipped with a sorting type f and I15 switching mechanism that can be changed from 9 to 9.

With such a threshing device, the handling efficiency can be improved by increasing the driving speed of the handling cylinder when threshing wheat, whose grains are less likely to be damaged than rice. For example, during the threshing process for rice, which generates less cut straw than wheat, it is possible to improve the grain collection efficiency by changing the sorting state of the sorting board to collect the grains in the /th direction and to make them more difficult. , it is possible to obtain the appropriate sorting state depending on the wheat, but conventionally, the gear shifting operation of the transmission device and the switching operation of the sorting state switching mechanism were performed separately, which made the operation difficult. Not only is this cumbersome and troublesome, but there is also a risk that due to an erroneous operation, it will not be possible to carry out handling and sorting processes in accordance with the target crop VC.

Zero shot:! This was developed in view of the above-mentioned actual situation, and it is possible to change the handling cylinder driving speed according to the target crop and change the sorting state of the oscillating sorting plate with simple operations.
The point is to be able to do it properly.

The characteristic structure of the threshing device according to the present invention is that the seven target crop selection operation tools are linked to the i++ transmission field and the Ufl selection mode deaf switching mechanism, and the effects are as follows. be.

That is, as the seven operation tools for selecting the target crop are operated, the speed change of the handling t+u drive speed and the switching of the sorting state of the oscillating sorting plate are performed at different speeds and sorting states according to the target crop. It can be done all at once.

Therefore, with simple operations on the seven operating tools, it is possible to accurately set the handling drum drive speed and sorting conditions according to the target crop, resulting in a threshing device that is more convenient to use as a whole. Ta.

Embodiments of the present invention will be described below based on the drawings.

The illustration shows a combine-mounted threshing device.1-1 A rotary handling cylinder f2+ (r-) is provided in a handling chamber (5) equipped with a receiving net (1) forming the lower wall, and the ear part is rotated into the handling chamber. A feed chain (3) is installed to clamp and transport the grain stalks while they are pushed into the interior, and a feed chain (3) is provided to transport the grain stalks while they are pushed inside. ) is provided with a swinging sorting plate (6) that separates the treated material from leakage without transporting it backwards, and a winnow (6) that blows a separate wind toward the rear. It is configured to collect the grains at the /th (7), the second grain at the second port (8), and send and discharge straw waste from the rear dust exhaust port (≦),
Furthermore, a cross-flow fan (10) for dust removal is provided.

A bevel gear transmission shaft (11) is supported on the handling trunk support shaft (2A), and a relay transmission shaft (12) to which engine power is transmitted by a belt are supported in parallel. Mat of slide gear (13A,) with outside spline
Accordingly, a gear transmission system ff (413) that changes the handling cylinder IJIIYr# speed W to a low speed state for rice use and a high speed state for running.
It is provided between both shafts (111 and (121).

A spring (18) is provided that urges (14B) to the downward retiring side of the grain pan 07, and a release lever (18) that pulls and moves the mesh (14A) + (14B) against the urging force is provided.
Nr Ke, by operating the release wire (19), one of the pair of mesh bodies (14A) and '(14B) is retired below the grain pan 07), and the other is made to protrude beyond the grain pan (17). While doing so,
The mesh body (14A) + (14B) can be selectively used. The large-mesh mesh (14A) can be used when treating rice, and the small-mesh mesh (14B) can be used when processing wheat.

) can change the amount of protrusion. When processing grains and rice, the amount of protrusion of the plate-like cutting l) is reduced to allow the processed material to fall freely toward the mouth (7)17, and when processing wheat, , the amount of protrusion of the plate-shaped body 1) is increased so that the processed material is at the first mouth (7)
It is so that it can fall to the side so that it does not fall off.

The net-like body motion release wire (19) and the plate-like motion motion release wire (24) are connected to the seven target crop selection operating tools and the seven gear shift levers, respectively, to control the handling barrel drive speed. You can change the speed, select the nets (14A) and (14B), and change the amount of protrusion of the rice all at once, depending on the crop, change the speed, use the net, and change the amount of projection. It is configured as follows.

Fig. 4 shows another example, in which a net-like body (a corrugated slide plate (2η) for opening and closing the starting end side of the lees) is overlapped with the grain pan (l'n, h) for No. 7 (7). A spring (2~) is provided on the opening side to press the slide ff

When implementing the present invention, various transmission devices can be used as the handling cylinder drive speed transmission device, such as a belt-type transmission device instead of the gear transmission device (Ia).

Also, sorting state switching machine! For iH7, two types of net-like bodies (14A') + (14B) with different eye sizes can be selectively used, or the plate-like body (21) can be freely changed in position. In addition to providing the stripe 411 (2η) so that its position can be changed, various configurations can be made.
