Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention sorts the processed material leaking from the receiving net below the handling cylinder by the specific gravity difference using a Glen pan, and continuously sorts it below the rear part of the Glen pan. The present invention relates to a thresher adapted to perform a leak screening with a provided grain sieve.

[Conventional technology]

Conventionally, the above-mentioned thresher has a flat surface, as shown in, for example, Japanese Utility Model Laid-Open No. 1-127627.

[Problems to be Solved by the Invention]

The threshing machine selects the threshing products by swinging a swinging sorting plate equipped with a Glen pan or a Glen sieve mainly back and forth, but since the Glen sieve is flat, the swing sorting plate is driven. There was a tendency for the resonance to occur relatively easily due to the vertical movement associated with.

The Glensieve has the important sorting function of not only leaking the best things such as paddy to the lowermost collecting section, but also conveying the unbranched paddy and straw debris backward without leaking. When the resonance phenomenon occurs, it vibrates violently up and down, and the first object to be leaked is conveyed, which hinders the sorting function and may damage the Glensive itself due to resonance.

It is an object of the present invention to prevent the above problems by preventing the resonance of the Glensieve as much as possible.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is characterized in that, in the threshing machine described at the beginning, the grain sheave is bent in a mountain fold shape at an intermediate portion in the front-rear direction in a side view.

[Action]

According to the above configuration, (a) the presence of the bent portion due to the bending improves the rigidity of the gren sheave in the up-and-down direction, so that resonance is less likely to occur.

In addition, the grensieve is usually arranged in a rearwardly upwardly inclined state, but the rearwardly upwardly inclined angle of the lower (rear) side of the processed product transporting (b) bent portion is gentler than that of the upper (front) side. Therefore, the processed material conveyed on the lower side surface is promptly conveyed.

Before the processed material is transferred to the Glensieve, the specific gravity difference is first sorted on the Glen pan.Since the paddy to be collected has a high specific gravity, it collects below the processed material layer, and the discharges such as straw chips have a specific gravity. Since it is light, it is transferred to the grain sieve after being collected above the processed material layer.

Therefore, in the first half of the grensive, the area where most of the material leaks is mainly, and in the latter half of the grensive, it is the area mainly for transporting straw debris backwards. The effect of (b) due to the fact that it is possible to quickly convey straw debris to the rear, which is convenient for improving the sorting ability of the Glensieve.

〔The invention's effect〕

Therefore, it is possible to provide a threshing machine which has an advantage that it is possible to suppress the damage of the Glensieve and the hindrance of the sorting performance due to the improvement of the rigidity due to the action of (a) and to improve the sorting efficiency by the action of (b). I was able to.

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the threshing machine includes a threshing section (A), a sorting section (B), a collecting section (C), and a second product reducing section.

The threshing part (A) is one in which a handling cylinder (2) is mounted in the handling chamber (1) and a receiving net (3) is stretched along the lower side of the handling cylinder (2). The culm that has been carried by the chain (4) is handled by the handling cylinder (2),
The processed material is leaked and supplied onto the sorting section (B).

The sorting section (B) is composed of a swing sorting device (5) and a Karako (6) which sends the sorting wind of the swing sorting device (5). The swing selecting device (5) is provided with a Glen pan (8) across both sides of a swingable frame body (7) and a continuous Glen sieve (9) below the rear of the Glen pan (8). , Upper and lower two-stage stroll (10), (1
1) is provided at the front and rear. Then, the processed product that has leaked from the receiving net (3) and has passed through the front part Glen pan (15) and the front stroke (16) is received by the Glen pan (8), and the rear Glen sieve (9) is selected while selecting the specific gravity difference. After oscillating and transferring to, the oscillating transfer to the rear is carried out while selecting the leakage by the Glencive (9), and the particles are dropped and discharged from the rear end. On the other hand, the treated product discharged from the dust delivery port (1a) of the handling chamber (1) is received by the upper straw rack (10), and is oscillatingly transferred to the rear while sorting the leakage, and the lower straw rack (11) is selected. To the outside of the machine, and the lower straw rack (11) again leaks and sorts and discharges from the rear end to the outside of the machine. In addition, (12) is a dust-exhaust fan for discharging the scraps of the dust together with the sorting wind.

The recovery part (C) is the first item recovery part (13) for recovering the paddy that has leaked from the Glensive (9), and is discharged from the rear end of the Glensive (9) or the Straw rack (1).
0) and (11), and a second product recovery section (14) for recovering the dropped rice with branches and the like. In the first item recovery section (13),
The first screw (13a) is provided to convey the collected first item to the horizontal side, and the second item recovery part (14) is a valley-shaped bottom part over the left and right vertical walls of the threshing transfer. A bottom case (14b) formed in a circular shape is provided, and a second screw (14a) is provided at the bottom of the bottom case (14b) to convey the collected second item to the horizontal side. There is.

As shown in FIGS. 2 and 3, the Glen Sieve (9) is used.
Is bent in a mountain fold shape in an intermediate portion in the front-rear direction in a side view, and the Glen pan (8) is positioned within the front side range of the rear end bending portion (X) on the front bending surface (9a) of the Glen sieve (9). The rear end position of the action is configured to be variable in the entire length so that it can be adjusted in the front-back direction.

The Glensive (9) is angled so as to have a rearward upward inclination, but the rearward upward inclination angle (θ ₁ ) of the rear bending surface (9b) due to bending is the rearward upward inclination angle (θ1) of the front bending surface (9a). It is more gradual than θ ₂ ).
