Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a movable Glen pan, which is slidable in the front and rear direction, at the front part of a grain sheave for recovering the first thing, and the leakage area of the Glen sheave can be adjusted by adjusting the movable Glen pan in the longitudinal direction. The present invention relates to a swing sorting device of a threshing device.

[0002]

2. Description of the Related Art In the rocking sorting device of the above threshing device, the leaking area of the Glensieeve can be changed by adjusting the front and back of the movable Glen pan. When the sorting operation range is expanded to improve the grain collection efficiency and the throughput is small,
There are advantages such as moving backward, narrowing the range of sorting action of the Glensieve, suppressing leakage due to the long distance sorting action of straw dust, and improving the sorting accuracy. Further, conventionally, the gren sheave on the lower side of the gren pan conveyance has been formed by a wire mesh in which wires are knitted in the vertical and horizontal directions.

[0003]

Generally, since metal materials have low water repellency, when the treated material is wet and threshing, water becomes droplets on the surface of the wire mesh and sucks straw debris into the wire mesh. The leakage area is reduced, and straw chips are easily stuck at the intersections of the vertical lines and the horizontal lines forming the mesh, which easily causes clogging. Then, when clogging occurs, the work is interrupted, or the work is continued, and the movable Glen pan is slid backward several times to perform the clogging removal work.
Straws that get stuck between the vertical line and the horizontal line cannot be easily removed, and the worker must remove them by picking them with his fingertips one by one, which has the disadvantage of spending a lot of time in removing clogging. It was Therefore, as a means for solving the above-mentioned drawback, it is conceivable to slow down the forward speed of the machine during wet threshing to reduce the processing amount, but in such a case, there is a disadvantage that the work efficiency decreases. An object of the present invention is to suppress the occurrence of clogging without reducing the work efficiency by devising the structure of the Glensieve.

[0004]

Means for Solving the Problems The characteristic construction of the rocking / sorting device of the threshing device of the present invention, which has been taken to achieve the above object, is as follows.
The grain sieve is made of a resin material, and the operation and effect are as follows.

[Operation] By forming the grain sieve with a resin material, it is possible to integrally form the vertical lines and the horizontal lines forming the mesh without removing the upper and lower steps of the vertical line and the horizontal line. Straws will not stick into the intersection of. In addition, the resin material has better water repellency than the metal material, and can suppress the attachment of straw scraps during wet threshing.

[0006]

As a result of the above construction, it is possible to suppress clogging in the Glensieve, and it is not necessary to reduce the traveling speed for throttling during wet threshing, and efficient work can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a threshing device mounted on a combine, in which the threshing treatment by the handling barrel 1 and the leakage of the net 2 are carried out by the Glen Pan 4 and the rack of the rocking sorting case 3. The rough chaff sieve 5 has undergone a rough sorting action, and the processed substance leaking through the chaff sheave 5 is subjected to a fine sorting action by the lower Glen pan 6 and Glen sieve 7,
The grain that has been made into a single grain by the precise sorting action and leaked through the Glensieve 7 is collected in the first thing collecting section 8, and the grain with a branch dropped from the end of the Glensieve 7 is collected in the second thing collecting section 9, The grain with branch collected in the second crop recovery section 9 is returned to the handling room A via the second crop reduction thrower 10 and reprocessed. Then, the small straw chips that have leaked from the grain sieve 7 together with the grains and the small straw chips that have dropped from the end of the grain sieve 7 together with the grain with the branches have the sorting air by the Karato 11 and the suction action by the dust exhaust fan 12. Received and discharged outside the device. Then, the relatively large straw debris that has fallen from the dust-sending port 13 at the end of the receiving net 2 is subjected to the sorting action by the upper and lower two-stage straw racks 14 and 15, and the grain with branches that has leaked through the straw racks 14 and 15. Is collected in the second product collecting section 9, and the relatively large shavings that have reached the end without leaking are discharged from the rear dust discharge port 16 to the outside of the machine. The Glen pan 6 for finely selecting the threshed products is divided into two parts, a first half and a second half, the first half is a fixed Glen pan 6a, and the second half is a movable Glen pan 6b, and the movable Glen pan 6b is provided near the control seat. The selection operation range of the Glen Sieve 7 can be changed by sliding the lever. The grain sheave 7 on the lower side of the grain pan 6 is formed of an ultra-high molecular weight polyethylene resin material having excellent wear resistance and water repellency so as to prevent trapping and adhesion of straw dust. The upper Straw rack 14 immediately below the dust inlet 13 is provided for each rack plate 1
The piano wire 14b is replaced every time one piece is skipped in order to prevent straw chips from being caught between the 4a and being difficult to fall.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
