Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a reinforcing structure for each part of a threshing device mounted on a combine harvester, etc., in which the crimp net can be easily removed for inspection and cleaning. .

(B) Prior Art A technology in which the crimp net of a threshing device is slidably removable so that it can be easily removed by opening the lid has been filed as a prior application by the same applicant.

(c) Problems to be solved by the invention However, the front end of the sliding rail for the crimp net is provided on the inner surface of the front plate of the handling chamber of the threshing device, and the rear end is attached to the partition plate that constitutes the end of the crimp net. was used as a mounting body for the sliding mounting rail. Therefore, the partition plate cannot be integrated with the crimp net as in the past, and only one partition plate is installed in the form of a bridge, and as shown in Figure 4, when a large amount of grain culm is processed, it is forced backward and bent. There was a problem that it was not possible to do so.

In the present invention, in order to improve the strength of this single independently cross-linked partition plate, a partition plate holder is fixed at the exit end, which is the terminal end of the crimp net that is slidably inserted.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained below.

In a threshing device, the side plate of the handling chamber at the bottom of the feed chain has an open lid that can be rotated to the side and the crimp net can be removed from the opening of the open lid, and the crimp net mounting rail is fixed. A partition plate holder 5 is provided at the exit end of the crimp net in order to prevent the partition plate from falling in the front-rear direction.

(e) Examples and effects Purpose of the present invention. The configuration is as described above, and the configuration and operation of the embodiment shown in the attached drawings will be explained.

Figure 1 is a front view of the open lid 12 and the crimp net taken out. Figure 2 is a front view of the crimp net stored and the open lid closed. Figure 3 is the open lid and the crimp net 2. Figure 4 is an enlarged front view showing the locked state of the partition plate 4. Figure 5 is a perspective view of the partition plate and the handling room front plate 3 with the crimp nets 1 and 2 removed. FIG. 6 is a perspective view showing the crimp net 2. FIG. 7 is a perspective view showing the assembled state of the crimp nets 1 and 2. FIG. 8 is a drawing showing the relationship between the partition plate 4 and the open lid 12.

This will be explained from FIGS. 1 and 2.

Reference numeral 16 denotes a handling barrel, on which handling teeth 17 are implanted.
An open lid 12 and crimp nets 1 and 2 are arranged around the rotating outer periphery of the handling cylinder. The opening lid 12 can be rotated and opened downward on the feed chain 11 side about a pivot shaft 14 of a bracket protruding from the threshing side plate 15. And feed chain 1
The first chain guide 13 is fixed on the open lid 12 side and rotated together.

The opening lid 12 can be opened over a wide range from the front plate of the handling chamber to the rear plate of the handling chamber, and since the partition plate is located in the middle, the feed chain side of the handling chamber cannot be fixed and can be opened from one side. This brings the situation close to normal.

The opening lid 12, together with the back opening forming an opening for taking out the crimp nets 1 and 2, serves to prevent the crimp nets 1 and 2 from coming off after insertion. That is, after inserting crimp nets 1 and 2 in order, open lid 1.
2, the crimp nets 1 and 2 are fixed in their proper positions without any play.

The front end of the crimp net is placed on the mounting rail 10 inside the handling room front plate 3, and the rear end is placed on the mounting rail 8 protruding inside the partition plate 4, and the crimp net is inserted in a sliding state. Therefore, the front end. Although the area near the rear end will not sag downward due to the pressure in the handling chamber, the central part of the crimp net in the front and back direction is reinforced to prevent it from sagging due to its long span. That is, the locking claw 1 at the insertion tip of the crimp net 1
9 is fully inserted, the handling chamber forming plate 28
The crimp net 1 is inserted into the slit of the locking plate 20.
This prevents bending at the center in the front-rear direction. Since the insertion tip of the crimp net 1 was supported by this locking pawl, this reinforcing force was applied to the crimp nets 1 and 2.
At the abutting portions of the crimp nets 1 and 2, the flow prevention claws 18 are connected to the rear ends of the crimp nets 1 and 2. It is reinforced by fitting into the slits in the locking plates 23 and 22 at the tip. As a result, the front and rear ends of the abutted portions of the crimp nets 1 and 2 are reinforced.

In order to support the bending of the crimp net 2 at the central position in the longitudinal direction, there is also a "to" on the inner surface of the open lid 12.
A support plate 9 in the shape of a square is protruded. When the open lid 12 is closed, this support plate 9 is attached to the crimp net 2.
It is inserted into the lower surface of the center in the front-rear direction, and suppresses deflection from below. 21 is a swinging sorting device.

The reason why the crimp net is divided into parts 1 and 2 is that if it were made into one piece, the arc would become larger, and even if the mounting rails 8 and 10 were slid, the outlet end would engage with the feed chain 11, making it difficult to extract. Because it becomes impossible.

As shown in FIG. 3, a support plate 9 shaped like a "he" that supports the central part of the crimp net in the front-rear direction from below.
is fixed to the open lid 12. Since the support plate 9 has an inclined front end, when the open lid is closed, the support plate 9 is gradually inserted under the crimp net from below. The crimp net 2 is placed on the mounting rail 10, and the lock portion 12a of the open lid 12 comes into contact with the end surface of the crimp net 2 on the exit side to prevent it from coming off.

Also, the upward stopper of the crimp net 2 is the fifth
By inserting the stopper pins 7, 7 shown in FIG. 6 and FIG. 6 into the holes of the engagement plates 6, 6 fixed to the crimp net 2, upward movement is prevented.

In addition, the locking plate 2 by the locking claws 18 and 19 described above
3, 22 into the slits also prevents the crimp nets 1, 2 from moving upward.

In response to such an overall configuration, the present invention is designed so that the independently bridged partition plate 4 will not bend backward due to being pushed by grain culms, straw waste, etc., as shown in Figure 4. It is something. In particular, as shown in FIG. 8, since the open lid 12 is provided over a wide area below the feed chain, most of the upper part of the partition plate 4 on the feed chain side becomes cantilevered. Therefore, the rear part bends as shown in Figure 4.

That is, as shown in FIGS. 6 and 7, the crimp net 2
A “dog”-shaped partition plate holder 5 is installed at the rear end of the outlet side.
has been established.

Therefore, the crimp net 2 is inserted following the crimp net 1, and finally the partition plate holder 5 provided at the end is inserted.
The partition plates 4 are held between them. The partition plate holder 5 is also provided with a slope at the tip of the insertion portion.
It is designed to gradually embrace 4.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, the crimp net can be easily taken out from the handling room, so if the threshing equipment becomes clogged or if you need to clean it completely after harvesting for the year, you can reach inside the sorting room and clean it. It became possible to do so.

Second, when configured in this way, the partition plates become independent bridges, which may result in insufficient strength and cause the partition plates to bend when a large amount of grain culms passes through. By providing the plate holder on the removable crimp screen, these problems can be overcome.

Also, for the same reason, there is no longer an accident where the partition plate is pushed by straw waste and falls over, which interferes with the rotating handling teeth.
