DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a swing sorting case in a threshing apparatus.

[0002]

2. Description of the Related Art As shown in Japanese Utility Model Unexamined Publication No. 3-129031, the supporting structure of a swing sorting case in a conventional threshing apparatus is such that the rear end side of the swing sorting case is connected via a crank swing mechanism. Supported, and the leading end side is supported via a slide guide mechanism comprising a guide rail and a guide roller, or as shown in Japanese Utility Model Application Laid-Open No. 58-4140, after a swing sorting case. There is a structure in which the end side is supported via a crank swing mechanism and the distal end side is supported via a swing link.

[0003]

As described above, in the case of a structure in which the leading end side of the swing sorting case is supported via a slide guide mechanism including a guide rail and a guide roller, when the swing sorting case is maintained. Although it has the advantage of quick and easy attachment and detachment of the swing sorting case,
At the time of threshing work, there is a disadvantage that noise due to the sliding contact noise between the guide rail and the guide roller is large. On the other hand, in the case of the structure in which the leading end side of the swing sorting case is supported via the swing link as in the latter case, although the noise caused by the swing link during threshing work is small, maintenance of the swing sorting case is performed. At times, the pivot shaft connecting the swing link provided outside the side wall of the threshing device and the swing sorting case provided in the threshing device is pulled out to connect the swing link and the swing sorting case. It must be released, and there is an inconvenience that it is difficult to quickly and easily attach and detach the swing sorting case.

According to the present invention, by devising the support structure of the swing sorting case, the swing sorting case can be quickly and easily attached and detached during maintenance, while the noise of the swing sorting case during threshing work is improved. The purpose is to reduce.

[0005]

[Action]

By supporting the front end side of the swing sorting case via the swing link, noise is smaller than when the front end side of the swing sorting case is supported via the slide guide mechanism. When the swing sorting case is removed for maintenance, when the fixing of the guide member is released, the swing link and the swing sorting case can be integrally pulled back along the guide rail. [Effects] As a result of the above-described configuration, while the noise of the swing sorting case during threshing work is low, the work of attaching and detaching the swing sorting case during maintenance can be performed quickly and easily.

According to a second aspect of the present invention, in the swing selection case, the swing movement of the swing link is permitted, but the swing link is prevented from falling when the swing selection case is detached. Stopper is provided. [Operation] When the swing sorting case is pulled out or the swing sorting case is inserted, the stopper prevents the swing link from falling down. [Effect] As a result of the above structure, the swing sorting case can be quickly and easily attached and detached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to a threshing apparatus mounted on a combine. As shown in FIG. 1, the threshing apparatus 1 performs a threshing process on a grain stalk conveyed by a feed chain 4 by a handling cylinder 2 and a receiving net 3, and a process that leaks from the receiving net 3. In an oscillating sorting case 5 that sorts materials into grains and straw chips, the upper grain pan 6 and the chaff sheave 7 in the swing sorting case 5 roughly sort the grains and straw chips, and the fine grain pan 8 and the grain sieve 9 perform fine sorting. Then, the first thing leaking from the Glen Sheave 9 is collected in the first thing collection unit 12 and discharged outside the machine, and the second thing such as the chaff with the branches discharged from the end of the Glen Sheave 9 is the second thing. The second product reduction device 1 which is collected in the collection unit 13
4 and is returned to the starting end of the swing sorting case 5 for reprocessing. And the dust outlet 3 at the rear end of the receiving net 3
Among the processed materials discharged from the a, the straw waste is discharged out of the machine via the first straw rack 10 and the second straw rack 11, and dust such as rice husk and small straw waste floating on the swing sorting case 5. Is discharged out of the apparatus by a sorting wind by Karino 15 and a suction wind by a dust exhaust fan 16. The swing sorting case 5 has a rear end supported by a crank swing mechanism A and a front end provided with a swing link 1.
7 is supported.

As shown in FIG. 4, to configure the crank swing mechanism A, the support shaft portions 19a at both ends, an arm portion 19b connected to each of the support shaft portions 19a, and both arm portions 19b are connected to each other. A split arm in which a crank arm 19 having a connecting rod portion 19c to be connected is attached to bearings 18, 18 attached to left and right side walls 1a of the threshing apparatus 1 in a double-supported manner, and is attached to the left and right of the rear bottom surface of the swing sorting case 5. The rolling bearing 21 of the bearing bracket 20 connects the left and right portions of the connecting rod portion of the crank arm 19 in an interlocking manner, and the swing selection case 5 is swung by the rotation of the crank arm 19. The connecting rod portion 19c and the arm portion 19b are connected via a key 19d and a retaining bolt 19e, and the split bearing bracket 20 is configured to be separable on the lid 20a side via a bolt 22. Therefore, when the cover 20a of the split bearing bracket 20 is removed, the connection between the swing sorting case 5 and the crank arm 19 is released.

As shown in FIGS. 2 and 3, the swing link 17 is swingably supported at the front of the swing sorting case 5 via a bracket 5a, and has a threshing device at its lower end. Yes includes a guide roller 24 as a guide member made of rollable roller bearing along the guide rail 23 provided on the first sidewall 1a, the guide rollers 24
Is attached to the link support mechanism provided on the side wall 1a of the threshing device 1.
Have been. On the other hand, at the tip of the guide rail 23,
A concave portion 23a for receiving and supporting the guide roller 24 at a predetermined position is formed, and the side wall 1 of the threshing apparatus 1 is formed.
a is provided with a fixing mechanism 25 for holding and fixing the roller 24 from above.
The link support mechanism is constituted by the id rail 23.
You. The fixing mechanism 25 is connected to a swing arm 26 pivotally supported on the side wall 1 a of the threshing device 1 so as to be rotatable around a horizontal axis, and connected to a swing end side of the swing arm 26. It is constituted by a bolt 27 with a knob which can move along the long hole 1b formed in the side wall 1a. A stopper 28 is provided on a side surface of the bracket 5a for restricting the swing link 17 from falling when the swing sorting case 5 is attached or detached.
Are bolted together. The stopper 28 includes a pair of front and rear stopper pieces 28a and 28b, and the interval between the pair of front and rear stopper pieces 28a and 28b is determined by the swing motion of the swing link 17 during the swing sorting operation. The swing range is set larger than the swing range, and the swing link 17 is configured to restrict the fall of the swing link 17 when the swing selection case 5 is attached or detached in a state where the swing motion of the swing link 17 is not hindered. .

[Other Embodiments] In the above embodiment, the guide member 24 is a rotatable roller, and the fixing mechanism 25 is a rocking mechanism for pressing the roller 24 which has fallen into the recess 23a of the guide rail 23 from above. Moving arm 2
