Description

[Detailed Description of the Invention] [Industrial field of application] The present invention threshes the recovered second product, then pumps it with a vertical feed screw conveyor, and discharges it from a reduction port at the upper end onto a Glen pan in the sorting section. And a threshing device configured to do so.

[Conventional technology]

In such a threshing device, the re-thresholded second product that had been pumped by the vertical feed screw conveyor was to be discharged from the reducing port onto the Glen pan using a discharge blade or the like (not described in the reference). .

[Problems to be solved by the invention]

However, the second object released on the Glen pan had a large deviation in the width direction, and in particular, a large number of the second object fell on the Glen pan far from the reduction port. When the second product is locally concentrated in this way, many second products are collected or discharged without being sufficiently subjected to the selection action, which is one of the causes of lowering the selection accuracy.

The present invention was created in view of such an actual situation, and an object thereof is to prevent a decrease in sorting accuracy due to a deviation of the second piece on the Glen pan in the width direction.

[Means for solving problems]

The characteristic feature of the present invention is that, in the plan view, at a plurality of positions in the lateral width direction on the lower part of the front end of the Glen pan, which is formed on an inclined surface that is lower on the lower side of the processed material transfer direction, in the plan view, the lower side of the processed material transfer direction. The vertical wall is arranged so as to be farther from the return port, and the vertical wall is made taller as it is farther from the return port, and the action and effect thereof are as follows.

[Action]

In other words, the second object released from the return port and trying to fall far away is erected on the side surface of the vertical wall, repelled and dispersed, and the deviation in the width direction is reduced.

Further, since the vertical wall is provided above the lower part of the front end of the Glen Pan, the second object reflected by the vertical wall falls onto the lower plate of the lower part and is also flowed down and transferred. Therefore, there is no accumulation of secondary matter at the flowed-down portion, and it is easy to spread over a wider area.

Furthermore, it is easy to obtain a more even distribution by utilizing the difference in height of the vertical walls.

[Effect of device]

As a result, it becomes possible to subject the second product released from the reducing port to a sufficient screening action, and the screening accuracy is improved.

After the specific gravity difference is sorted, the latter is oscillated and transferred to the rear Glensieve (9), and then the latter is oscillated and transferred to the rear while the leakage is sorted by the Glensieeve (9), and is dropped and discharged from the rear end. On the other hand, the processed material discharged from the dust inlet (1a) of the handling room (1) is treated with the upper straw rack.
It is received by (10), swings backward while sorting for leakage, discharges to the lower Straw rack (11), again leaks sorted by the lower Straw rack (11), and discharges from the rear end to the outside of the machine. To do.
Incidentally, (12) is a dust-exhausting fan for discharging straw dust together with the sorting wind to the outside of the machine.

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 (10), (11). ) And a second crop recovery unit (14) for recovering branched rice and the like. The first item recovery part (13) has the first screw (13a) for conveying the recovered first item to one side, and the second item recovery part (14) has the second item recovered. A second screw (14a) is provided to convey the item to one side.

At the end of the second screw (14a), as shown in FIG. 5, four discharge blades (15) facing in the circumferential direction are provided at intervals of 90 degrees. ), Six processing teeth (16) are attached at equal intervals in the axial direction, and the processing blade (15) and the processing teeth (16) form a processing rotating body (D). The processing tooth (16) is in the shape of a flat blade, and handles the second material sent by the second screw (14a) while unraveling it to make it into single particles. Also, the above-mentioned loose blade (1
Reference numeral 5) is a plate body, which strikes the second object to further granulate it and feeds it to the starting end of the second vertical feed screw conveyor (20) through the connecting case (18) described later by the punching action. .

The connecting case (18) with a front spread is connected to the front side of the processing case (17) containing the processing rotator (D), and the discharge port (19) of the connecting case (18) has the second The starting ends of the vertical feed screw conveyors (20) are connected for communication.

The processing case (17) has an arc shape along the locus of the tip of the processing tooth (16), and a cleaning port (21) is formed on the front peripheral surface thereof. This cleaning port (21) is usually closed by a lid (22) that is bolted to the processing case (17) .If necessary, remove the bolt (23a) and remove the lid (22). You can easily open it. The lid (22)
A receiving blade (24) is planted inside of the so that it is inserted into the gap of the rotation locus of the processing tooth (16). The receiving blade (24) serves to assist the treating tooth (16) and unravel the sent second material to make it into a single grain.
