Description

[Detailed description of the invention] Industrial field of application The invention relates to a diffusion plate in a screw-type threshing machine.

Prior Art In a threshing machine with a screw-type handling barrel built into the handling chamber, a diffusion plate is provided between the spirals and is integrated with the spirals.

Problems to be Solved by the Invention As mentioned above, in the case where a diffuser plate is provided between the spirals, power is wasted because the diffuser plate is integrated with the spiral, and the spiral pitch is Due to large manufacturing errors, it was virtually a one-piece product.

Means for solving the problem Therefore, the technical problem of this proposal is to create a threshing machine that can use power efficiently, and the technical means of this proposal to solve this technical problem is The diffuser plate is removable from the spiral,
Moreover, the mounting angle can be adjusted freely.

Effects of the invention According to this technical means, it is possible to use power efficiently, and it is also possible to create a structure that can absorb the pitch error of the spiral, making it easy to manufacture. can be prevented.

Embodiment First, a conventional full-feed type axial flow combine shown in FIG. 8 will be explained.

The crops are raked in by a raking reel 1 and cut by a cutting blade 2, and the cut crops are transported from a raking auger 3 to a handling room 6 by a chain conveyor 5 in a feeder house 4, and then to a screw-type handling barrel 7. The grain is threshed. The threshed grains fall from the receiving net 8 to the swinging sorting board 9, and are sorted by the blower fan 10 and the swinging sorting board 9.

During this sorting process, grains and fine straw waste leak downward from the sorting plate, and only long straw is carried toward the dust outlet 11.

The leakage material including grains that has fallen from the sorting board is subjected to sorting air by a blower fan 12 such as a winnowing machine, and the grains fall into the first gutter 13, the second grains fall into the second gutter 14, and are transferred to the first gutter. The grains that fell on 13 are on the grain frying conveyor 1
5, the paddy is transported to a tank 16, and the second paddy is returned to a sorting board 9 via a thrower tube 17.

18 is a crawler equipped with a thresher, 19
indicates the control section.

Further, the discharge culm portion of the handling chamber is composed of a discharge vane 20 at the rear end of the handling cylinder and a casing 6a.

The present invention relates to an improvement of the above-described combine harvester in which a diffuser plate is provided between the spirals.

In FIGS. 1 and 2, 21 indicates a diffusion plate, and when installing the diffusion plate 21 between the spirals 7a,
Attach the angled mounting fittings 22, 22 to the spiral wall with bolts and nuts 25, 26, and insert the bolts 23 that pass through the protruding parts of the fittings 22, 22 into the long holes 24 of the diffusion plate 21 to fix the diffusion plate. . One of the bolt nuts 25 and 26 serves as a pivot point, and the angle fitting 22,
22 can be rotated, and the angle fittings 22, 22 can be mounted by selecting any of the mounting holes 27, 28, 29. This allows the mounting angle of the diffuser plate 21 to be changed.

The above is one method for attaching the diffuser plate 21, but it may also be attached in the following manner.

That is, as shown in Figures 3 and 4, the mounting bracket 22 is made into a U-shaped cross section, into which both ends of the diffusion plate 21 are inserted, and fixed with bolts and nuts 23. 22
A is a long hole that can be adjusted freely.

The mounting bracket 22 can be mounted to the spiral wall by rotating around the bolt nut 26 as a fulcrum in the same manner as described above, and selecting one of the holes 27, 28, and 29 and fixing it with the bolt nut 25.

Providing the elongated holes in the diffuser plate 21 or the mounting fittings 22 as described above is convenient when the length of the span cannot be determined.

The above-described diffuser plate 21 can be fixed at any mounting angle and can also be removed.

The ones shown in Figures 5 and 6 automatically change the mounting angle due to overload.

That is, the diffusion plate 21 is attached to the handling barrel 7 by the mounting bolts 3.
Balls 33, which are energized by springs 32 in holes 34 on both sides of the cross beam 21a fixed to the upper part of the diffuser plate 21 with bolts 31, are hinged to a fixed fixture 29 fixed at 1. Matching hole 35,3
6 and 37.

The lower ball 33 shown in FIG. 5 is a slider 38
The slider 38 is further energized by a spring 40 in the hole 39.

According to the above-described diffusion plate 21, when an overload is applied, the ball 33 resists the force of the springs 32, 40, slips out of any of the engagement holes 35, 36, and 37, and tilts. It is designed to prevent damage.

In addition, in the one shown in FIG. 7, a rectangular slide nut 41 is fitted into a square hole 42 so that it can slide, and a bolt 42 screwed into the slide nut 41 is attached to the spiral 7a. The diffuser plate 21 is fixed by screwing it in.

In any case, according to the present invention, the diffuser plate 21 is removable and its mounting angle is adjustable, so the mounting angle can be changed according to the power loss, and it can be removed as necessary. Can be done.

Depending on the mounting structure, pitch errors can be absorbed.
