Description

[Detailed explanation of the idea] The present invention relates to a handling cylinder modification tool.

In conventional threshing machines, foreign objects such as pieces of wood that enter the handling barrel chamber collide with the handling teeth, causing the handling barrel near the attachment part of the handling teeth to become dented, reducing threshing performance. Maintenance was time-consuming because the handling cylinder had to be removed from the machine, the side plates removed, and the unevenness had to be corrected with a hammer from the inside.

The present invention aims to provide a handling barrel correction tool that can easily correct irregularities in the handling barrel without removing it from the threshing machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The handling barrel modification tool of the present invention will be explained below based on illustrative drawings.

In FIGS. 1 and 2, 1 is a handling barrel of a threshing machine, 2 is a loop-shaped handling tooth attached to the handling barrel 1, and a recess 3 is formed around the attachment part of the handling tooth 2 of the handling barrel 1. It is occurring.

Reference numeral 4 denotes a hook bolt, which has a hook portion 4a that engages with the handle teeth 2 at one end, and a nut 5 for moving the hook bolt 4 in and out of the hook bolt 4, which has a threaded portion 4b at the other end. .

Reference numeral 6 denotes an arm in which this hook bolt 4 is inserted into a bolt hole 7 provided in the center, and the hook bolt 4, which is engaged with the handle teeth 2 at the hook portion 4a, can be moved vertically by rotating the nut 5 with a spanner. Index the moving tooth 2.

A pair of supports 8 are opposed to each other and sandwich the arm 6 from the left and right sides, and are supported on the handling cylinder 1.

The supports 8 each include struts 10 welded to both ends of a base plate 9, each having a contact surface 9a that contacts the curved circumferential direction of the handling cylinder 1.
．． 11, and the arm 6 is pivotally supported at one end by a bolt nut 12 between the upper ends of the support column 10 on one end side so as to be swingable in the axial direction of the hook bolt 4.

13 is a post 11 on the other end side of the arm 6 that supports the free end of the arm 6.
This is a bolt/nut that penetrates and supports between the upper ends of the .

13a is a support 11 through which this bolt/nut 13 is passed.
A plurality of bolt holes are provided, and the arm 6 can be fixed not only horizontally but also at an angle as appropriate.

The bolt hole 13a can be formed into a long groove along with the bolt hole of the arm 6, and in this case, the arm 6 can be supported at any inclination angle.

When the recess 3 of the handling cylinder 1 is formed on both of the attachment parts of the handling teeth 2, this handling cylinder correction tool can be used by moving the base plate 9 along the circumferential direction of the handling cylinder 1 as shown in FIG. It is placed on both sides of the handling tooth 2, and the handling tooth 2 is indexed directly upward with a hook bolt 4.

The concave portion 3 around the attachment portion of the handling tooth 2 is pulled up by both legs of the handling tooth 2 until it comes into contact with the contact surface 9a of the substrate 9, respectively, and is corrected to its original state.

When the recess 3 is formed only on one side of the attachment part of the handling tooth 2 as shown in Fig. 3, the free end of the arm 6 on the opposite side to the recess 3 should be lowered as shown in Fig. 4. The handling cylinder 1 is corrected by tilting it and fixing it, and pulling the handling teeth 2 obliquely upward.

According to the handling barrel modification tool of the present invention, supports are arranged astride both sides of the handling tooth which has a recess in the handling barrel surface around the attachment part, and an arm in which a hook bolt that engages with the handling tooth is inserted is installed. By fixing it at an appropriate mounting angle and pulling the handling teeth in a desired direction, surface irregularities can be easily and quickly corrected while the handling barrel remains attached to the threshing machine.
