Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an attachment device for a net-dividing partition plate in a thresher mounted on a combine or a harvester.

[Prior Art and Problems to be Solved] The netting partition plate in the threshing machine is erected on the inner surface of the net along the rotation direction of the handling teeth planted in the handling cylinder. It is common to use a crimp net type in which a steel wire rod of is woven in a grid shape in a receiving net frame, and it is difficult to stand and fix the partition plate in a stable state with respect to such a receiving net. For example, a partition plate is welded to the seat plate, the receiving net is sandwiched by the seat plate, the bolt insertion plates are opposed to each other, and bolts are fixed from the outside of the receiving net.
162, etc.).

However, the above-described mounting method has a drawback that the seat plate and the bolt insertion plate block the meshing of the partition plate mounting portion and reduce the net leakage area of the corner.

In other words, if the grains shredded in the handling room are transferred to the rear of the handling room, they will be mixed with straw waste and become dust particles, and subsequent sorting will be difficult or easily scattered at number 3. Although it is desirable to cause leakage at the start end side, if the leakage area of the receiving net decreases, the backward transfer amount of grain will increase correspondingly and it will adversely affect the sorting operation. Even the reduction in area cannot be neglected.

In particular, when a large amount of straw debris is generated in the handling room (the amount of supply of the handling room of the grain culm is large) or when the wet material threshing in which the net is easily clogged, the adverse effect thereof becomes remarkable.

[Means for Solving the Problem] Therefore, according to the present invention, a receiving net is arranged in a lower region of a handling cylinder in which handling teeth are implanted in a peripheral surface, and an inner surface of the receiving net is arranged along a rotating direction of the handling teeth. In order to vertically hang down a flat plate-shaped receiving net partition plate, a flat plate facing outward on the outer surface of the receiving net is formed on the receiving net partition plate along a vertical wire constituting the receiving net. By connecting and fixing, it is intended to solve the above problems.

[Operation] Therefore, according to the present invention, the net-dividing partition plate is securely fixed in one-sided upright state by the mounting flat plate provided on the outer surface along the vertical wire of the net. The mesh of the receiving net is not blocked by the member, and the initial leakage area of the receiving net is effectively maintained.

Further, since the plate body is integrally connected to the net-receiving frame, the rigidity of the whole net-receiving net is further enhanced.

[Embodiment] The construction of the present invention will be described with reference to an embodiment shown in the drawings. In a handling chamber 5 divided by a handling chamber front side plate 1, a rear side plate 2, a cylinder cover 3 and a crimp-shaped receiving net 4. Has
A handling cylinder 7 having a large number of handling teeth 6 planted on its outer periphery is rotatably supported, and a sorting unit 8 formed below the handling chamber 5 is integrally provided with a fine grain leakage net 9a at its tip. A swing selecting body 9 composed of a corrugated plate 9b having no hole is arranged. Numeral 10 is Kara-no-to for the drafting wind, 11 is the No. 1 spiral, 12 is the No. 2 reducing thrower, and No. 2 such as cuttings and branch adhering grains are transferred to the side of the machine by the No. 2 spiral not shown. After that, it is returned to the inside of the handling room 5 by the second reduction thrower 12 and reprocessed.

Although 13 is a suction fan, 14 is a feed chain, and 15 is a grain culm entrance, the standing grain culm in the field is not shown, but it is cut by the pretreatment section and is lifted by the lifting and conveying device, and is fed from the end of the feed chain. And is continuously fed into the handling room 5,
In the process of passing through the inside of the handling chamber 5, the shredding process is performed.

The culm after the shredding process is discharged from a culm outlet (not shown), transferred to the rear of the machine by a straw chain, shredded or bound, and the processed matter leaking through the net 4 swings. Specific gravity and wind are sorted on the sorting body 9, and the fine grain (No. 1) leaks through the fine grain leaking net 9a, and the No. 1 spiral 11, and then the deep grain is stored in a hopper or the like in a fried grain cylinder not shown. In addition, a suction fan for light dust etc.
It is designed to be discharged outside the machine at 13.

On the other hand, a drive shaft that swings the swing selection body 9 via the cam 16.
Fans 19 and 19 are integrally fixed to the left and right bearings 18 and 18 in proximity to the left and right bearings 17, and a space portion a is provided between the swing selecting body 9 and the threshing side plates 20 and 20a. By blowing the wind from the space a into the space a, the paddy leakage from the rocking sorting body 9 is eliminated, and the selection of the grains on the rocking sorting body 9 is improved. It should be noted that a resin net 21 may be provided at both left and right ends of the swing selecting body 9 to close the space portion a. Further, conventionally, a band-shaped rubber was provided in a sliding portion of the swing selecting body 9 with respect to the side plates 20 and 20a so as to prevent paddy leakage. However, it was possible to solve the problem with the simple structure as described above.

By the way, it is the same as the prior art that the mesh net partition plate 22 is erected on the inner surface of the mesh net along the rotation direction of the meshing teeth 6 planted in the cylinder 7, but the present invention constitutes the mesh net 4. A flat plate 23 is vertically fixed to the net frame 24 along the vertical wire 4a and is integrally fixed to the net frame 24, and the net partition plate 22 formed of a flat plate is connected to the flat plate 23 like the flat plate 23. It is fixed.

That is, the receiving net partition plate 22 imparts an appropriate amount of resistance to the processed material that remains in the handling chamber 5 to promote the shedding action, and the shed grains (most of the grains are on the starting end side of the handling chamber). Be shredded in)
It plays an important role for threshing, such as letting it leak to the first half of the handling room without transferring it to the end of the handling room.
The detailed description of the mounting structure of the net partition plate 22 in the present invention
The receiving net 4 is formed by crimping a vertical wire rod 4a and a horizontal wire rod 4b made of steel in a lattice pattern and is stretched around the receiving net frame 24. Wire 4a
A bow-shaped flat plate 23 is arranged in a standing shape immediately below the outer surface side of the net frame 24, and both longitudinal ends of the flat plate 23 are welded to the net frame 24 to sandwich the vertical wire 4a between them. The mesh partition plate 22 is placed on the flat plate 23, and the U-shaped clamp 25 clamps the mesh partition plate 22 and the flat plate 23 and welds them to the clamp 25, the flat plate 23 and the mesh partition plate 22.

With such a partition plate mounting structure, the net screen partition plate 22 can be easily installed without reducing the mesh of the net screen 4, and the flat plate 23 and the net screen partition plate 22 are connected to the net screen frame 24. Since they are integrally connected, the rigidity of the frame structure of the receiving net frame 24 is improved.
Instead of the U-shaped clamp 25, left and right sandwiching members 25a and 25b may be used (see FIG. 4).

In addition, as shown in FIGS. 5 and 6, the net receiving partition plate 22
The lower part of the projection may be projected downward at predetermined intervals and the projection 22a may be welded to one side of the flat plate 23, or the flat plate may be connected via a connecting member 26 such as a round bar thinner than the mesh. 23 and the net partition plate 22 may be welded together (see FIGS. 7 to 9).

[Advantage of the Invention] As described above, the present invention arranges the receiving net in the lower region of the operating cylinder in which the operating teeth are planted on the peripheral surface, and the inner surface of the receiving net is directed inward along the rotation direction of the operating teeth. In order to hang a flat plate-shaped receiving net partition plate, a flat plate outwardly standing on the outer surface of the receiving net is connected and fixed to the receiving net partition plate along the vertical wire constituting the receiving net in a one-sided manner. Therefore, the rigidity of the receiving net frame can be increased by integrating the receiving net frame and each component of the mounting device, but with a simple configuration using only a flat plate material. , It is possible to eliminate the problem that the receiving net mounting member reduces the leakage area of the receiving net as in the past, and to attach the receiving net partition plate, and also the workability of attaching each component to the receiving net. It has an extremely useful practical effect that it can be increased.
