[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus provided with a screw-type second reduction device for reducing the second product supplied from a second recovery portion to the front of a swing sorting portion.

[0002]

2. Description of the Related Art Conventionally, as a second reduction device, a second product is conveyed by rotating around a longitudinal axis of the vertical feed tube into a vertical feed tube provided with a reduction port for discharging a reduced product at an upper portion thereof. A vertical feed screw is provided, and discharge blades for returning the second product to the swinging sorting unit are provided continuously above the vertical feed screw. As such a second reduction device, the second material recovered by the second recovery unit is conveyed by a vertically feeding screw rotating at a substantially constant speed, and is discharged and reduced from the reduction port to the swing sorting unit by the blade. However, since the discharge speed is substantially constant, the reduced No. 2 material accumulates on the oscillating sorting unit in a non-uniform manner, and the sorting width of the oscillating sorting unit cannot be sufficiently utilized, resulting in deterioration of the sorting performance. There was a fear. As a means for solving such a problem, an adjusting plate capable of adjusting the angle is provided below the reducing port, and the angle of the adjusting plate is adjusted up and down to change the discharge distance of the second product, and to perform swing sorting. It has been proposed that the second object be uniformly dispersed on a plate (see Japanese Utility Model Laid-Open No. 3-105230).

[0003]

According to such a conventional means, the reductant can be uniformly distributed and supplied to the oscillating sorter. However, it is necessary to provide a device for adjusting the angle of the adjusting plate, and in particular, it is necessary to provide an automatic adjusting device. In order to be adjustable, the structure becomes complicated and the cost increases. An object of the present invention is to provide a simple improvement to a reduction port for discharging a reduced substance formed in a screw type second-piece reduction apparatus, thereby enabling a reduced material to be oscillated and sorted without a special discharge control device. The purpose of the present invention is to make it possible to uniformly disperse and reduce.

[0004]

The present invention is characterized in that a guide member which can swing open and close with a fulcrum on an upper side of a reductant for discharging a reductant provided in a screw-type second reducing device described at the beginning is provided on a closing side. In that it is provided with a bias.

[0005]

According to the above technical means, the guide member is opened by the pressing force due to the collision of the reductant colliding with the guide member. That is, the opening angle of the guide member is determined by the speed and amount of the reduced product discharged from the reducing port by the second product reducing device, and the discharging speed of the reduced product is determined by the rotation of the discharge blade connected to the vertical screw. It is determined by the power output by speed. Therefore, the guide member constantly changes its opening angle due to a slight change in the rotation speed of the vertical feed screw during operation and a change in the discharge amount of the reductant, and the guide member is discharged by the blades. The reductant collides, changes the discharge trajectory, and can be uniformly dispersed on the oscillating sorter.

[0006]

As is apparent from the above description, the guide member capable of swinging opening and closing is urged toward the upper side of the return opening, so that the reduced material is oscillated and sorted without a special opening angle adjusting device. It can be distributed and supplied without being shifted upward, and the sorting performance can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows an overall side view of the threshing device mounted on the combine. The basic configuration of this threshing apparatus is the same as the conventional one, and is provided along the handling cylinder 2 mounted on the handling chamber 1, the feed chain 3 for nipping and transporting the grain culm in the handling chamber 1, and disposed below the handling cylinder 2. Receiving net 4, swinging sorting unit 5 arranged from the bottom to the back of the handling room 1, Karamin 6 for supplying sorting wind, 1st collecting unit 7 for collecting fine particles (1st item), 2nd item No. 2 collection unit 8 that collects, and a second sorting unit 5 that swings the collected second thing
And a dust exhaust fan 10 that absorbs dust from above the rear part of the swinging sorter 5 and discharges it to the outside of the machine. The second reduction device 9
As shown in FIG. 1, a reducing port 1 for discharging the reductant is provided at the upper part.
1 is provided with a blade 13 for discharging the reductant at the upper end thereof in a vertical feeding cylinder 12 and a longitudinal feeding screw 14 for conveying the reductant.
Is mounted on a shaft. A plate-like guide member 15 that can swing and open and close is urged toward the closing side by a pressing force generated by discharging the reductant, with the upper side of the reducing port 11 as a fulcrum P. The guide member 15 normally closes the return port 11 by its own weight.
The second product collected by the second collection unit 8 is conveyed by the second collection unit 9, and is discharged from the reduction port 11 by the blade 13 vigorously. The guide member 15 is pushed open around the fulcrum P by a pressing force that constantly changes according to the amount and the discharge speed of the discharged reductate, and the opening angle can be constantly changed. When the opening angle of the guide member 15 is constantly changed, the reductant discharged from the return port 11 is uniformly dispersed on the swing sorting unit 5 by changing the discharge trajectory when the reductant collides with the guide member 15. Can be sorted out.

Another Embodiment In the above embodiment, as shown in FIG. 3, the guide member 15 may be formed in a vertical lattice shape.
The reduced material discharged through the lattices 5 and the reduced material colliding with the lattice and changing the falling direction can be dispersed and dropped on the swing sorting unit 5.

In the claims of the utility model registration, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
