DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing sorting case, in which a coarse sorting section for receiving and roughly sorting processed materials leaked from a receiving net, and carefully sorting the processed materials leaked from the rough sorting portion. Separately, a grain sieve for allowing the fine granules to leak to the material recovery section is provided, and a plurality of sieving lines are provided between the coarse separation section and the Glen sieve in a cantilever shape extending toward the lower side in the transfer direction of the processed material. The present invention relates to a sorting unit structure of a threshing device, which is provided side by side and provided with a Karamin for sending a sorting wind inside the swing sorting case.

[0002]

2. Description of the Related Art In a conventional sorting unit structure of a threshing apparatus, the plurality of sieve wires are fixed to the transfer end of a Glen pan fixed to a swing sorting case.

[0003]

In the sorter structure of this type of threshing apparatus, a plurality of sieve lines are swung together with the grain pan with the swinging of the swing sorting case, and the swinging of the grain pan is performed. Deflection under the inertia force and the load of the threshing process from the rough sorting by the crushing, loosen the grain, branching chaff, straw waste, and chopped and entangled in the sorting process and separate them. Developed to increase the efficiency of grain recovery by promoting wind separation to reduce the incorporation of straw debris, etc., leaking from between adjacent ones of multiple sieve lines into the sorted product. However, according to the above-described conventional configuration, the amount of deflection of the sieve wire does not become too large due to restrictions on the material and the wire diameter, and the loosening effect given to the grain or the like becomes insufficient. To improve the efficiency of grain recovery It could not be.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. 7-8097, a sieve wire is supported on a Glen pan so as to be freely swingable around a horizontal axis over a predetermined range, and the sieve wire is moved in a swing sorting case. Sorting unit of a threshing device configured to make complex and large movements, in which the swinging of the sieve line itself due to the inertia force and the like caused by the swinging of the Glenpan, and the swinging of the sieve line itself due to the swinging of the Glenpan The structure was proposed.

[0005] However, despite the necessity of a loosening action of the above-mentioned grain, branching paddy, straw chips, cut straw, etc. by a sieve line as the number of processed materials increases, the sieve line in the above-described structure is more effective than the grain pan. Due to the structure that swings freely around the horizontal axis, the sieve line becomes difficult to swing by the load of the treated material when the amount of the treated material is large, and the loosening action given to the grain or the like becomes insufficient. However, there has been a problem that the grain collection efficiency is reduced.

[0006] It is an object of the present invention to increase the efficiency of grain recovery by enabling the threshing process to increase the separation effect of the sieving line regardless of the amount of the processed product.

[0007]

[Means for Solving the Problems]

[Configuration] The characteristic configuration of the invention according to claim 1 is that, in the sorting unit structure of the threshing apparatus described at the beginning, the plurality of sieve lines are configured to be swingable around a horizontal axis center on a base end side, An oscillating drive mechanism for oscillating the sieve wire is provided.

According to a second feature of the present invention, in the sorting unit structure of the threshing apparatus described at the beginning, the base end side of the sieve wire is supported on the threshing apparatus main body side so as to be swingable around a horizontal axis. So that the relative displacement between the swing sorting case and the threshing apparatus main body caused by the swinging of the swing sorting case is mechanically converted into the swing displacement of the sieve line. That is, the swing sorting case is mechanically linked to the swing sorting case.

According to the first aspect of the present invention, the plurality of sieve lines are oscillated around the horizontal axis on the base end side by the oscillating drive, so that the amount of the processed material is large and the sieve is sieved. Even if a heavy weight is applied to the wire, the sieve wire swings reliably over the set range, and entangles in the sorted material to loosen the mixed grain, branch-attached paddy, straw debris, and cut straw to promote their separation. In addition, it is possible to suppress the inflow of straw waste and the like leaking from between adjacent ones of the plurality of sieve lines into the sorted material by the wind sorting action.

According to the second aspect of the present invention, the relative displacement between the swing sorting case and the threshing apparatus main body caused by the swing of the swing sorting case is mechanically converted into the swing displacement of the sieve line. Therefore, even if the amount of material to be processed is large and the sieve line is heavy, the sieve line swings reliably over the set range,
Grain, husks, straw chips, and chopped straw that are mixed and entangled in the sorted material to promote their separation, and straw chips that leak from between adjacent ones of multiple sieve lines, etc. Is suppressed by the wind sorting action. Further, since the sieve wire is swung by using the swing driving force of the swing sorting case as described above, it is not necessary to newly provide a drive unit for swinging the sieve wire, and the number of parts is increased. It can be suppressed and can be manufactured at low cost.

[Effects] Therefore, according to the configuration of claim 1, it is possible to increase the grain collection efficiency regardless of the amount of the processed material.

According to the second aspect of the invention, regardless of the size of the processed material, the grain collection efficiency can be improved, the structure can be simplified, and the manufacturing cost can be reduced.
