Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a culm collecting device for a combine harvester.

[Conventional technology and problems]

In a combine harvester, the grain culms are reaped, the threshed and threshed culms are dropped and accumulated on a culm collecting body that faces backward from a rotating shaft mounted horizontally at the rear of the combine harvester.
When the loading and unloading culm reaches the set weight, the spring is elastically installed between the front end of the rocking plate, which is provided facing forward on the opposite side of the culm assembly, and the combine main body with respect to the above-mentioned rotation axis. In the culm collecting device of a combine harvester, which rotates the culm collecting body downward and discharges the collected culm into the field, one end of the spring is fixedly connected to the front end of the rocking plate. When the amount of discharged culms successively accumulated on the culm assembly approaches the set weight, the culm assembly gradually moves downward against the elasticity of the springs. This results in the spring elasticity being increased in proportion to the downward rotation of the culm aggregate, and by the slow downward rotation of the culm aggregate, the expelled culms are collectively released into the field. It is released in a scattered manner over a wide area. Therefore, there are problems such as a lot of labor and time being required for post-treatment of the culms released into the field.

[Purpose of the invention]

The present invention was developed in view of these circumstances, and it solves the problems of the prior art with a simple yet rational configuration, and instantly reduces the elasticity of the spring when the culm is turned downward at a certain angle. It is an object of the present invention to provide a culm collecting device that can weaken the culm and rapidly rotate the culm collecting body downward to release the culm in lumps, thereby saving labor and eliminating the need for post-processing.

[Structure of the invention]

The configuration of the present invention that solves the problems of the prior art is to reap the grain culms and remove the threshed culms in a combine harvester.
It is dropped and accumulated on a collecting culm that faces backward with respect to a rotating shaft installed horizontally at the rear of the combine, and when this collecting culm reaches a set weight, it is collected with respect to the rotating shaft. The collected culms are rotated downward against the elasticity of the springs installed between the front end of the rocking plate, which faces forward opposite to the culms, and the main body of the combine, and the collected waste culms are released into the field. In the device,
The angle θ on the rotation shaft side where the longitudinal axis of the rocking plate intersects with the axial direction of the spring is formed to be an obtuse angle, and the connecting point of the spring to the front end of the rocking plate is set in the direction of the rotation axis. It is characterized by being able to move and return.

〔Example〕

Embodiments of the invention will be described in detail with reference to the drawings.

FIG. 1 is a side view, and FIG. 2 is a perspective view of the main structure.

FIG. 3 is a side view of the same as above, FIG. 4 is an explanatory diagram showing the correspondence between the culm aggregate and two rocking plates in an unloaded state, and FIG. 5 is an explanatory diagram showing the correspondence at a set load.

In FIG. 1, A is the combine main body, B is the reaping section, C is the automatic threshing device, D is the traveling body, and E is the culm collecting device.

Next, the configuration of the culm collection device E will be explained.

Reference numeral 1 denotes a rotating shaft that is horizontally mounted between the left and right receiving brackets 2 and 3 provided on the rear wall of the combine main body A. A culm collection body 4 that maintains this is attached to the combine main body A in the rearward direction.

Further, a rear end of a swing plate 5 is attached to one end of the rotation shaft 1 in a forward direction opposite to the culm collection 4 so as to maintain a substantially horizontal posture when no load is applied. A guide slot 6 is formed in the swing plate 5 along its longitudinal direction, and as is clear from FIG. A rotor 8 which is pivotally supported between the vertical pieces of the movable frame 7 is fitted so as to be slidable and movable.

Reference numeral 9 denotes a spring whose upper end is connected to the lower surface of the sliding frame 7. The lower end of the spring 9 has elasticity, more specifically, a plurality of springs for setting and adjusting the amount of discharged culms accumulated on the culm collecting body 4. Adjustment hole 10a
is connected to the upper end of the spring receiver 10 which has been drilled therein. An arbitrary adjustment hole 10a formed in this spring receiver 10 is fitted into a metal fitting receiver 11 attached to the side surface of the combine main body A, in this embodiment, the side surface of the receiving metal fitting 3.

As is particularly clear from FIG. 4, the angle θ on the rotating shaft 1 side where the longitudinal axis a of the rocking plate 5 intersects with the axial direction of the spring 9 is an obtuse angle. This angle θ
is not specified, since it varies depending on the angle of the culm aggregate 4 when no load is applied, but it is preferably about 100° to 105°. Specifically, when a set weight of waste culms is accumulated on the culm collecting body 4 and the collected culms 4 are rotated downward to the extent that the accumulated waste culms do not fall out, the angle θ becomes smaller than 90°. , the angle θ is selected such that the trochanter 8 within the guide slot 6 rapidly moves in the direction of the rotation axis 1. Culm collecting device E
is configured as described above.

In the figure, 12 is a culm transporting body that supplies the culm that has been threshed by the automatic threshing device C to the culm collecting device E, and 13 is a culm transporting body that prevents excessive rotation of the rotation shaft 1 by the spring 9. 4 is fixed to the rotation shaft 1.

[For production]

Next, the effect will be explained. The grain culms cut by the cutting section B of the combine main body A are sent to the automatic threshing device C,
This is where the grain is threshed. The threshed culm is fed by falling from the culm conveyor 12 onto the culm collector 4 in a substantially horizontal position.

When a set weight of waste culms is accumulated on the culm collection body 4, the culm collection body 4 is rotated downward to C in FIGS. 3 and 5 due to this weight. This angle is an angle at which the accumulated culms on the culm aggregate 4 do not fall off. When the culm assembly 4 rotates downward to position C, the fifth
As is clear from the figure, the longitudinal axis a of the rocking plate 5,
The angle θ formed by the axial direction of the spring 9 becomes smaller than 90°, and at this point the trochanter 8 slides using the guide slot 6 as a guide, and the trochanter 8 approaches the rotating shaft 1. This results in a sudden weakening of the elasticity of the spring 9, and the culm aggregate 4 pivots downward all at once to position d, leaving the accumulated culms in the field in the form of a block. collection! #The culm aggregate 4 that released the culm is
Due to the elasticity of the spring 9, it returns to its old state, that is, the posture shown in FIG.

This operation is repeated continuously.

When the accumulated culm exceeds a set weight, it is of course possible to rotate the culm downward against the spring and leave the accumulated culm in the field. (b) Particularly in the present invention,
The angle θ on the rotation axis side where the longitudinal axis of the rocking plate intersects with the axial direction of the spring is an obtuse angle, and the connecting shape of the spring to the front end of the rocking plate is moved in the direction of the rotation axis, and fX
Since TX regression was used, when the accumulated culm reaches the set weight, the angle θ is set to 90 by the initial action of the downward rotating culm.
°, and the connecting point between the rocking plate and the spring is brought close to each other in the direction of the rotation axis to rapidly reduce the elasticity of the spring.
By this action, the culm aggregate can be rotated downward at once, and the accumulated waste culm can be left in the field in the form of a lump.

(c) By leaving the culms in the form of a nodule, it is possible to save labor in processing waste culms in the field compared to the conventional technology.
