More specifically, the present invention relates to a threshing tooth having a substantially V-shaped rod-like tooth main body and a plate tooth disposed inside the outer periphery of the tooth main body and within the tooth thickness.
[0002]
[Prior art]
Threshing teeth described above, that is, threshing teeth comprising a substantially V-shaped rod-shaped teeth body and a plate teeth disposed within the outer periphery of the teeth body and within the thickness of the teeth body. BACKGROUND ART Teeth are conventionally known (for example, see Patent Document 1). Specifically, as shown in (a) and (b) of FIG. 9, a threshing tooth in which a plate tooth 15 is disposed at the center in the thickness direction of the thickness of the tooth body 14 is formed. Are known.
[0003]
[Patent Document 1]
Published Japanese Utility Model Application No. 6-45425 (FIG. 4)
[0004]
[Problems to be solved by the invention]
However, according to the above-mentioned conventional technique, since the plate teeth are considerably penetrated inward in the thickness direction of the tooth body, the surface of the plate teeth does not effectively feed threshing material. However, the threshing material feeding function could not be sufficiently exhibited.
[0005]
An object of the present invention is to improve the feeding function for threshing.
[0006]
[Means for Solving the Problems]
The features, functions and effects of the threshing tooth according to the first aspect of the present invention are as follows.
[0007]
〔Characteristic〕
A threshing tooth comprising a substantially V-shaped bar-shaped tooth main body and a plate tooth disposed within the outer periphery of the tooth main body and within the thickness of the tooth main body, wherein the tooth is provided. The plate handle is disposed at a position deviated to the lower side in the threshing material feeding direction within the thickness of the main body.
[0008]
[Action]
Since the plate teeth are arranged at positions deviated to the lower side in the threshing feed direction within the thickness of the tooth body, the surface of the plate teeth efficiently feeds threshing. .
[0009]
〔effect〕
Therefore, the feed performance for threshing can be improved by a simple structural improvement only by devising the arrangement of the plate handling teeth.
[0010]
The features, operations and effects of the threshing tooth according to the second aspect of the present invention are as follows.
[0011]
〔Characteristic〕
In the threshing tooth according to the first aspect of the present invention, a contact that contacts the tooth body and the plate tooth so as to prevent the plate tooth from moving upward in the threshing feed direction. The point is that a part is formed.
[0012]
[Action]
The contact portion is formed between the tooth body and the plate tooth so that the feed tooth body opposes the feed reaction force acting on the plate tooth. It is possible to reliably feed threshing material by preventing the deformation of the stripped teeth and improve durability.
[0013]
〔effect〕
Therefore, it is possible to ensure the feeding action for the thresh and improve the durability.
[0014]

[0017]
As shown in detail in FIGS. 4 (a) and 4 (b), the tooth 13 has a substantially V-shaped rod-shaped tooth main body 14 and an inside of the contour of the tooth main body 14 and the tooth main body 14. And plate handle teeth 15 arranged within the thickness.
The gripping tooth body 14 has a round bar shape, and at both ends thereof, a male screw portion 14a for screwing to the peripheral surface of the body 7 is formed. 7, and the nut 16 is screwed and fastened to the penetrating male screw portion 14a, so that the nut 16 is mounted on the body 7.
The plate handle teeth 15 are composed of a mounting flange portion 15a that comes into contact with the peripheral surface of the body 7 and an operating plate portion 15b that rises from the mounting flange portion 15a. The flange portion 15a is formed by the male screw portion 14a and the nut 16. It is attached to the trunk body 7 by being fastened together with the trunk body 7.
[0018]
The plate teeth 15 are arranged at positions deviated to the lower side in the threshing feed direction within the thickness of the teeth body 14, and the plate teeth 15 and the teeth body 14 are Are formed with contact portions b and a that contact each other so as to prevent the plate handling teeth 15 from moving toward the upstream side in the threshing material feeding direction. The contact portion a of the tooth body 14 is composed of an arc portion extending from the inner periphery to the outer periphery, and the contact portion b of the plate tooth 15 is composed of the outer periphery.
[0019]
The handling teeth 13 are mounted on the trunk body 7 in a posture along a spiral. That is, the action plate portion 15b of the plate handling tooth 15 is spiral.
[0020]
As shown in FIG. 5, the cone cap 9 is formed by forming a plurality of leak holes 18 in a plate 17 in a circumferential direction and in a direction along an axis of a handling cylinder. 6, and a long hole extending in the direction along the axis of the handling cylinder as shown in FIG. As shown in FIG. 8, the leak hole 18 is formed by a burring process of 60 degrees or more, and the end 19 of the entangled bent portion around the leak hole 18 generated at the time of working is a hole larger than the plate material 17. It is formed so as to protrude inward in the penetration direction.
[0021]
The sorting chamber 10 is provided with an oscillating sorter 20 for sieving and sorting the leaked material. At the bottom of the sorting chamber 10, a first-piece collecting section 21 and a second-piece collecting section 22 are formed. ing.
