Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a tooth handling device in a threshing machine.

Conventional technology Conventional tooth extraction devices have rod-shaped treatment teeth implanted on the circumference of the treatment barrel.
The structure is such that the shell culm is shed as the handling cylinder rotates.

Problems to be Solved by the Invention In the conventional device described above, the handling teeth are rod-shaped, and although they can divide the grain into left and right sides, they cannot open it widely, so the grain is inserted into the culm. It was difficult to separate and thresh some grains.

As a result, the shredded grains were ejected from the machine along with the waste straw, resulting in the fourth loss.

means to solve the problem This invention aims to solve the above-mentioned problems.

The following measures were taken.

That is, a rod-shaped split tooth is provided on the outer circumferential surface of the rotating handling cylinder on the front side in the rotation direction, and widening teeth are implanted that have a portion that expands in the left and right direction as it goes rearward in the rotation direction from the split tooth. It is set up.

Action/Effect The culm supplied to the handling chamber is threshed by a large number of handling teeth and is forced to the discharge side, and when it reaches the handling tooth device consisting of split teeth and widening teeth near the exit. First, it is divided into left and right parts by the dividing teeth, and then further divided into left and right parts by the expanding teeth.

Therefore, the grains embedded in the culm are separated from the culm and fall into the handling chamber.

In this way, the invention allows the grains to be removed at the end of the threshing process.
It has the effect of removing grains and preventing grain loss.

The threshing machine of the embodiment <1) has a handling barrel (3) mounted on an internal shaft in a handling chamber (2), a supply port (4) on one side, a straw discharge port (5) on the other side, and a straw removal port (5) on the front side. Along the handling opening (6), insert the pinching and conveying device (
7).

The handling barrel (3) has a large number of handling teeth (8) (8y...
・ is implanted, and split teeth (
9) and a tooth handling device 0]) consisting of an expanded tooth αO is implanted.

Therefore, each embodiment of the tooth handling device (11) will be specifically described based on the drawings.

First, in the first embodiment, as shown in FIGS. 1, 2, and 3, a rod-shaped split tooth (9
) are implanted, and expansion teeth 00 are implanted in the left-right direction at positions at appropriate intervals behind them.

Then, between both teeth (9) and 00, an expansion plate (6) forming a part of the expansion tooth QO having a triangular planar shape is provided, and the base part is connected to the expansion tooth a.
It is configured by being attached to O.

Next, the configuration of the second embodiment shown in FIGS. 4 and 5 is as follows.
Split tooth (9) and expansion plate (2)! : are integrally welded to improve strength and prevent straw, etc. from getting stuck in the gaps.

The third embodiment shown in FIGS. 6, 7, and 8 is as follows:
The split tooth (9) on the front side in the rotational direction of the handling barrel (3) and the expansion tooth a1 implanted in the left-right direction on the rear side are integrally connected as shown in the drawing.

In addition, in the fourth embodiment shown in FIGS. 9 and 10, the tip portions of the expansion teeth 01, which are separately implanted on the left and right sides of the front side, are integrally constructed by welding to the front split teeth (9), and the expansion plate 0 It has a configuration that does not include a pier.

Next, the embodiments shown in FIGS. 11 and 12 and FIGS. 13 and 14 show other modifications of the split tooth (9) and the expansion tooth OQ.

When the threshing operation is started with the configuration as described above, the husks supplied from the supply port (4) to the handling chamber (2) are conveyed while being held at the base by the pinching and conveying device (7). , handling torso (
Along with the rotation of 3), the grain is threshed by each of the handling teeth (8) and (8)'.

υ In this way, the culm that has not been threshed and has reached the terminal end of the handling barrel (3) is first divided into left and right parts by the rotating dividing teeth (9) K, and then by the expanding teeth that follow. This results in the head opening wider to the left and right.

Therefore, the grains interposed between the grain culms are dropped downward.

In this way, the tooth extraction device 0υ can expand the successive culm groups to the left and right by the cooperative action of the dividing teeth (9) and the expanding teeth QO to remove the grains. .

Note that the same effect can be achieved even if the front edge of the expansion tooth (meaning the front edge of the expansion plate a sand) is used as the equivalent of the split tooth (9).
