Description

[Detailed Description of the Invention] The object of the present invention is to facilitate the maintenance work of the threshing machine by making it possible to easily take out the handling cylinder from the handling room when repairing the inside of the threshing machine.

This invention divides the handling trunk shaft into three parts: a pair of left and right shaft supports, and a handling trunk support section that is located between both shaft supports, is movable in the axial direction, and can be connected and separated from both shaft supports. To provide a handling barrel attaching/detaching device for a threshing machine in which a foil case facing a handling barrel side wall is detachable from a handling chamber machine wall, and a handling barrel is removable from a handling chamber.

The following will explain the embodiments shown in the drawings.

Referring to FIG. 1, 1 is a handling barrel, 2 is a handling tooth, 3 is a lid, and 4 and 5 are handling room machine walls. The handling room machine wall 4 has an input case 6 and a bearing 7 fixed to a side plate on the grain culm entrance side. A drive case 8 and a bearing 9 are fixed to the handling room machine wall 5 at a side plate on the grain culm exit side.
The drive case 8 is equipped with a PTO shaft, a bevel gear, etc. for power transmission to a straw removal device, a straw removal binding machine, etc.

In implementing the present invention, the handling trunk shaft 10 includes a handling trunk support portion 10A and a pair of left and right shaft supports 10B, 10.
It is divided into three parts, B′ and B′. The shaft support 10B is rotatably supported by a bearing 7, and the shaft support 10B' is rotatably supported by a bearing 9.
A can be freely connected to each other via the first connecting body (pin clutch) 11, and the shaft support 10B' and the handling barrel support 1
0A can be freely connected via a second connecting body (shaft connecting body) 12.

The second connection body (shaft connection body) 12 is a shaft support 10
B' and the handling cylinder support part 10A and spline engagement P,
It passes through an inner hole 12a having a spline groove for P', and is movable in the axial direction A and A' from the threaded part 22 by turning the handle 21, so that it can come in contact with the bearing 9 and with the shaft support 10B'. Its range of movement is limited by the detachable arrangement and suitable locking means 13. A part of the circumferential surface of the shaft connecting body is formed into a polygonal surface 12b, and the side wall (wheel on the exit side) 1a of the handling barrel 1
The handle cylinder 1 is configured to be engaged with a polygonal hole 14a formed in the center of a flange 14 integral with the handle cylinder 1, so that the handle cylinder 1 is rotated integrally with the handle cylinder shaft 10 when the handle cylinder shaft 10 is rotated.

A flange 1 integrated with the side wall 1b on the inlet side of the handling cylinder 1
The inner hole 15a of 5 is loosely engaged with the circumferential surface of the circular axis of the handling barrel support part 10A, and the flange 15 is rotated in the rotational direction with the key 16.
The handling cylinder 1 and the handling cylinder support part 10A are locked to each other so as to be relatively movable in the axial direction, and a fixing means 20 (see Fig. 3) is provided to freely fix the handling cylinder 1 and the handling cylinder support part 10A. do.

Foil case 1 attached to the handling trunk side of the handling room machine wall 5
7, as shown in Figures 2 and 3, a plurality of screws 1
The head 19a of 9 is caulked and fixed, and the shaft part 1 between the circular part 19b and the head 19b is prevented from slipping.
9c is inserted into the long hole 18 of the handling room machine wall 5 from the handling room side into the large diameter portion 18a, and then grasp the non-slip part and move the foil case 17 to the handling drum rotation direction (during threshing) side of the handling drum 1. It is rotated and fixed to the small-diameter separator portion 18b of the elongated hole 18 portion of the handling room machine wall 5. Foil case 17
To remove it from the handling room unit wall 5, it is sufficient to perform the reverse action when it was installed. In other words, grip the non-slip part of the screw 19 on the opposite side of the handling barrel rotation direction (during threshing), rotate the foil case 17, remove it from the large diameter part of the long hole 18 toward the handling chamber, and then remove the handling barrel. It is configured so that it can be taken out from the handling room at the same time as 1.

Threshing is carried out in the condition shown in Figure 1. That is, the handling cylinder 1 is integrated with the handling cylinder support part 10A by the fixing means,
Connect the handling trunk support part 10A to the first connecting body (pin clutch)
11 to the shaft support 10B, and connected to the shaft support 10B' through the second connection body (shaft connection body) 12 to connect the handling trunk support portion 10A and both shaft supports 10B, 10.
B' is integrated to form the handling barrel shaft 10.

When repairing damage to the handling teeth 2 or other parts of the inside of the threshing section, remove the ceiling board (not shown) of the handling chamber and then lift the handling barrel 1 upwards into the handling chamber.
The shaft supports 10B and 10B' of the handling trunk shaft and the handling trunk support part 1
0A is separated and the foil case 17 is removed from the handling room unit wall 5.

To do this, move the foil case 17 in the direction C.
The second connecting body (shaft connecting body) 12 is rotated by an angle and falls into the space H, and the second connecting body (shaft connecting body) 12 is moved in the direction A by turning the handle 21 to become independent of the shaft support 10B', and the handle 20a of the fixing means 20 is moved to the second position. After rotating the flange 15 and the handling cylinder support part 10A in the direction shown in FIG.
The pin 11a of the first connecting body (pin clutch) 11 is removed from the pin hole 11b to make the handling cylinder independent from the shaft support 10B (see FIG. 4).

As described above, in the present invention, the handling cylinder shaft 10 is connected to the handling cylinder support part 10A and the pair of left and right shaft supports 10B, 10.
B′ and three parts, and the connecting bodies 11 and 12
Since the foil case 17 facing the handling cylinder side wall can be freely connected to each other through the handling cylinder side wall and can be detached from the handling compartment machine wall 5, the foil case 17 can be dropped from the handling compartment machine wall 5 and the handling cylinder of the handling cylinder shaft 10 can be connected to the handling cylinder. Support part 10A
The handling cylinder 1 can be easily removed from the handling chamber by uncoupling it from the double shaft supports 10B and 10B', and a space can be secured for the handling cylinder 1, making it easier to repair the inside of the threshing machine. When repairing or replacing the handling tooth 2 erected on the handling cylinder 1, there is an effect that the handling cylinder can be placed on a workbench or the like and the work can be done in a comfortable posture.
