DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking and sorting apparatus for a threshing machine such as a combine, and more particularly, to fill a gap between the left and right side walls of a threshing machine casing and the left and right side walls of a rocking and sorting machine with a sealing material. The present invention relates to a swing sorting device.

[0002]

2. Description of the Related Art Conventionally, when a gap between the left and right side walls of a threshing machine casing and the left and right side walls of a swing sorting machine is filled with a sealing material, a structure in which the sealing material is provided on the left and right sidewalls of the threshing machine casing, and a swing sorting machine. Are provided on the left and right side walls. The former was of the hanging type, in which rubber plates fixed to the left and right side walls of the threshing machine case were hung inward from the upper edges of the left and right side walls of the swing sorting machine. The latter is a plug-in type in which a sealing body for inserting and holding the upper edges of the left and right side walls of the swinging sorter through cuts is integrally formed with a contact piece whose tip is in close contact with the left and right side walls of the threshing machine. There was also a presser plate type in which a rubber plate was sandwiched between upper and lower side walls of a rocking sorter with a presser plate and fastened with bolts to fix the rubber plate, and the end of the rubber plate was in close contact with the left and right side walls of the threshing machine. .

[0003]

The conventional hanging curtain type has a problem that the effective sorting width of the swing sorting machine is reduced and the sorting ability is reduced, and it is preferable that the sealing material is provided on the swing sorting machine. However, in the case of the plug-in type, the sealing material is easily displaced by the sliding contact between the contact piece and the left and right side walls of the threshing machine housing. Although it is formed, it is possible to prevent vertical displacement, but it is not possible to prevent front and rear displacement, and because the resistance part is formed, the seal body can be inserted from above into the upper edges of the left and right side walls of the swing sorting machine. It becomes impossible to insert the seal body into the upper edge of the left and right side wall of the swinging sorting machine from the front end or the rear end over the entire length, which is troublesome, and furthermore, it is necessary to tighten with bolts etc. in order to prevent front and rear displacement There are more There is a problem that the mounting work becomes difficult. On the other hand, the presser plate type can prevent the rubber plate from slipping, but has the problem that the work of tightening bolts and the like is required as in the above case, and the workability of the mounting is poor.

According to the present invention, a sealing material for filling a gap between the left and right side walls of the threshing machine casing and the left and right side walls of the swinging sorting machine is securely fixed to the left and right side walls of the swinging sorting machine, and can be easily mounted. It is a main object of the present invention to provide an oscillating sorting apparatus as described above.

[0005]

According to a first aspect of the present invention, there is provided an oscillating sorting apparatus, comprising: a seal made of an elastic material which fills a gap between left and right side walls of a threshing machine casing and left and right side walls of an oscillating sorting board. Material, and a fitting portion to be fitted into a groove formed on the left and right side wall of the swing sorting machine, a projection fitted into a hole formed on the left and right sidewall of the swing sorting machine, and a retaining portion of the projection Are integrally formed with the sealing material with an elastic material, and a swing sorter
The groove is formed on the upper outer surface of the left and right side walls of the swing sorting machine.
A hole penetrating through the inner surfaces of the left and right side walls is formed in the inner surface of the groove .

[0006]

The swing sorting apparatus according to the present invention having the above-described structure is configured such that the fitting portions of the sealing material are fitted from outside to the grooves formed on the left and right side walls of the swing sorting board, and the retaining portions are fitted into the holes. The seal member can be fixed to the left and right side walls of the swinging sorter by a simple operation of press-fitting the protrusion having the shape. After mounting, the seal material is fitted with the hole and the protrusion, and the plastic deformation force of the fitting part is also helped, the front and rear and up and down displacement are reliably prevented, the sealing performance is improved, the seal material and the left and right side walls of the threshing machine casing Thus, it is possible to reliably prevent leakage of the sorted material (grain loss) without generating a gap between the material and the material.
Further, by reducing the number of parts of the seal structure, the assembling workability can be improved and the manufacturing cost can be reduced.
