Description

[Detailed Description of the Invention] This invention relates to a guide device for a sorting plate in a DC type combine harvester.

In order to clarify the gist of this invention, the structure and operation of a DC combine harvester will first be explained using FIG. A culm pulling reel 4, a cutting blade 5, an auxiliary conveyor 6, etc. are provided, and the grain culm cut by the reaping section 2 is conveyed horizontally to the center of the machine or to one side by an auger 7 and the machine body 1 side. The grains are conveyed by a feeder conveyor 8 that feeds them vertically, and sent to a handling room 9 where they undergo threshing processing. After that, use straw walker 1 to remove the straw.
At the same time, grain bread 13
Karakino 14, Chafushive 15, Glensieve 16
The grains are sorted using
It will be carried out at 8.

In this way, in the case of a DC type combine harvester, a straw walker 10 is provided at the rear of the handling room 9, and a chaff sheave 15 is provided at the lower part of the straw walker 10, so that the straw walker 10 falls from the straw walker 10, and from the grain pan 13 directly below the handling room. The grains mixed with straw waste being sent are sorted and separated into straw waste and grains by the chaff sieve 15, the straw waste is discharged outside the machine, and the grains are allowed to flow down onto the lower grain sieve 16 for further sorting. This is usually how it is done. Further, the chaff sheave 15 is constituted by a large number of sheaves protruding in parallel within a frame, while the grain sheave 16 is made of punched metal.

By the way, in the case of the chaff sheave 15 and grain sheave 16, it is necessary to change and adjust the opening degree of the chaff sheave 15 depending on the crop to be harvested, and to select and use grain sheaves 16 with different hole diameters. It must be easy to attach and detach. However, when the chaf sheave 15 and grain sheave 16 are inserted into the chap case, their front and rear ends in the insertion direction are installed on the support member. This is a natural consideration because the grains are subjected to the sorting action on the entire surface of these members 15, 16, but with this front and rear end support structure, the posture of these members 15, 16 during insertion becomes unstable, Particularly for models that do not use the left and right horizontal bars that are long in the longitudinal direction as guides, it is recommended that the front ends of these members 15 and 16 be thrust into engagement with the support member (the members are long in the longitudinal direction, and the insertion opening is at the rear of the fuselage). It was difficult to perform this task (as it was established in 2013), and the process had to be done while relying on the intuition of the workers, which resulted in a complicated process.

Therefore, the object of this invention is to provide a device that can quickly and easily bring the front ends of the chaff sheave and grain sheave into engagement with the receiving member provided in the sorting chamber without relying on the above-mentioned intuition.

That is, this invention provides a sorting plate in a sorting chamber of a DC type combine harvester so that it can be inserted and removed while sliding, and a support member is provided in the sorting chamber to support the front and rear edges of the sorting plate in the insertion/extraction direction. , it is a guide device of a sorting plate in which terminal guide plates for inserting into the receiving part members are individually provided on the left and right over a narrow range in the front and rear, between both receiving part members and at a position just before the front end side receiving part member. Features.

According to this, the front end of the sorting plate at the time of insertion comes into contact with the final guide plate for insertion at a position just before the front end side receiving part member, and the positioning of the sorting plate insertion posture is determined when it is about to enter into the receiving part member. Therefore, just by pushing the sorting plate in accordance with this final guide plate for insertion, the sorting plate is automatically and accurately plunged into engagement with the front end side receiving part member, and the insertion work of the sorting plate is completed. It's easy to do.

Hereinafter, one embodiment of this invention will be explained using FIGS. 2 to 4. Reference numeral 19 in these figures is a chaff case, which is installed inside the sorting chamber 12 of the fuselage 1. A chaff sheave 15 and a grain sheave 16 are installed inside the sheave 19 so that they can be inserted and removed in a vertically overlapping manner. That is, the chaff case 19
Receiving members 20 and 21 are installed in upper and lower two stages, respectively, across the left and right inner walls 19a, 19a and at the front and rear in the insertion/extraction direction, and at approximately intermediate positions of the front and rear receiving members 20, 21 on the upper and lower sides, respectively. Intermediate guide plates 22, 22 are provided on the inner walls 19a, 19a.
is fixed in a protruding state, and each front end side support member 2
Similarly, the inner walls 19a, 19a are located immediately before 0, 20.
Terminal guide plates 23, 23 with narrow front and rear widths are fixed to the left and right individually in a protruding state. In this case, in order to support the chaf sheave 15 and grain sheave 16 set in an inclined position so that they do not slip down, the support members 20, 20 on the front end side are formed in a substantially C shape such that the tips of the chaf sheave and grain sheave engage with each other. It is formed in a letter-shaped or approximately U-shaped cross section. Further, it is desirable to use curved substantially chevron-shaped members for the terminal guide plates 23, 23 so that the chaff sheave 15 and grain sheave 16 can easily ride on and get over them.

The chaf sheave 15 and the grain sheave 16 are inserted into the chaff case 19 through the rear end side support members 21 and 21, respectively, and first the intermediate guide plate 2
2 and 22, the peripheral frames 15a and 1 of each sheave 15 and 16
Guide in the insertion direction is performed by placing both side edges of 6a, and when each sheave 15, 16 comes into contact with the terminal guide plates 23, 23 and rides on and overcomes them, it automatically moves to the front end side. receiving part material 20,
The front end of the sheave is thrust into engagement with 20. In this state, each sheave 15, 16 is connected to the rear end side support member 2.
1 and 21, for example, by bolt connection or the like.

In this way, the present invention provides terminal guide plates with narrow front and rear widths on the left and right sides between the support members supporting the front and rear edges of the sorting plate and at the position immediately before the front end side support member. Because of this, the sorting plate can be slid and inserted accurately and easily without using long guide bars at the front and rear that are easily clogged with straw waste, and it is also effective in saving materials used.
