[0026]
In the configuration as described above, the gist of the present invention resides in the configuration of the handling cylinder 11 and the concave 12, and the configuration according to the following will be described with reference to FIGS.
[0027]
That is, as shown in FIGS. 2 and 3, the handling cylinder 11 includes a cylindrical handling cylinder body 13 extending in the front-rear direction and an introduction body 14 attached to the front end portion of the handling cylinder body 13. The handling cylinder body 13 and the introduction body 14 are coaxially attached to a handling cylinder support shaft 17 installed between a pair of front and rear handling cylinder supports 15 and 16 provided in the handling chamber 10, and the same handling cylinder. The support shaft 17 is integrally rotated. 18 is a barrel drive pulley.
[0028]
As shown in FIGS. 3 to 5, a large number of teeth 20 formed by bending a rod-like body into a substantially inverted U shape are projected on the outer peripheral surface of the barrel body 13. The outer peripheral surface of approximately two-thirds located on the front side of the entire length of the main body 13 becomes the dust feeding tooth handling region Z1, and the inside of each tooth handling tooth 20 protruding from the outer circumferential surface located in the dust feeding tooth handling region Z1. At the position, a dust handling tooth 21 formed in a plate shape is projected to form a double tooth handling. Z2 is a tooth handling area.
[0029]
Here, the first chaff sheave 45 of the sorting section 6 is arranged at a position directly below the dust feeding tooth handling area Z1, and the second of the sorting section 6 is placed at a position directly below the tooth handling area Z2. Chaff sheave 46 is arranged.
[0030]
The dust handling tooth 21 is formed so that the outer shape of the peripheral edge is substantially similar to the inner shape of the tooth handling 20, and the distance between the peripheral edge of the dust feeding tooth 21 and the tooth handling 20 Is made smaller.
[0031]
Further, the tooth handle 20 is formed with male screw portions 20a, 20a at both ends, and the male screw portions 20a, 20a are inserted into the male screw portion insertion holes 13a, 13a formed in the handle barrel main body 13, respectively. Nuts 20b and 20b are screwed onto the male screw portions 20a and 20a.
[0032]
The dust feed tooth 21 is integrally attached to the barrel body 13 via a base end attachment piece 21a.
[0033]
In this way, the plate-shaped dust handling teeth 21 project from the inner positions of a large number of teeth handling teeth 20 formed by bending the rod-like body into a substantially inverted U shape. It is possible to prevent the inner side of 20 from being almost closed by the dust feeding teeth 21 and preventing the grain handle or the heel portion of the waste from being caught on the teeth 20.
[0034]
In addition, the dust handling teeth 21 act to send dust to the cereals and waste, and the waste is smoothly fed into the dust (direction toward the waste treatment unit 7 along the axial direction of the barrel body 13). Can be discharged.
[0035]
Accordingly, in the dust feeding tooth handling area Z1 immediately above the first chaff sheave 45, dust and waste are delivered relatively quickly, while in the tooth handling area Z2 just above the second chaff sheave 46 The threshing and the scouring dust are sent relatively slowly, and the threshing is performed efficiently.
[0036]
Further, as shown in FIG. 2, the introduction body 14 includes an introduction body main body 22 formed with a reduced diameter from the front end portion of the handling body 13 to the front, and a screw formed on the outer peripheral surface of the introduction body main body 22. The cereal grains that are formed from the conveyor-like introduction piece 23 and are conveyed by the conveyance unit 4 are introduced to the handling cylinder 11 side.
[0037]
As shown in FIGS. 4 and 6, the concave 12 includes a concave main body 25 formed in a mesh shape, and a plurality of partition bodies 26 attached to the upper surface side of the concave main body 25 so as to protrude from each other. ing.
[0038]
The concave main body 25 is formed by connecting four divided forming bodies 27, 28, 29, and 30 that form front, rear, left and right side portions.
[0039]
Moreover, each of the divided formed bodies 27, 28, 29, 30 is formed in a rectangular frame shape in plan view, and in the front-rear direction on the support frame bodies 31, 32, 33, 34 formed in a quarter arc shape in the front view. A plurality of front and rear extension rods 35 extending in parallel to each other are installed in parallel in the direction of the arc, and reinforcing rods 36 extending in the direction intersecting between the lower ends of the front and rear extension rods 35 are spaced in the front and rear direction. The reinforcing rods 36 intersect with the front and rear extension rods 35 (dust feeding direction) at an acute angle.
[0040]
Furthermore, the interval W2 between the reinforcing rods 36, 36 adjacent in the front-rear direction is set to be larger than the interval W1 between the front-rear extension rods 35, 35 adjacent in the left-right direction, and preferably 5W1 <W2. The relational expression is established.
[0041]
In this way, the concave portion is prevented from being clogged in the concave body 25 even when the amount of movement of the flange portion in the dust feeding direction is large.
[0042]
Further, the partition 26 is formed along the upper end edge of each reinforcing rod 36 described above, and is formed so as to protrude above the upper end of the front / rear extension rod 35 (to the tooth handling 20 side of the handling cylinder 11). Yes.
[0043]
Thus, along the outer peripheral surface of the handling cylinder 11 that threshs while rotating, the waste that is spirally transferred is attached to the upper surface side of the concave body 25 in a protruding manner, and the dust feeding direction By the plurality of partitions 26 that are extended and arranged in a direction that forms an acute angle, it is possible to smoothly guide in the dust feeding direction, and the waste can be discharged efficiently.
[0044]
Therefore, the waste does not stagnate on the concave 12, and the problem that abnormal noise is generated due to the stagnation of waste can be prevented.
[0045]
Further, at the start end portion of the concave body 25 and on one side facing the rotation direction of the handling cylinder 11, that is, in the divided formation body 27 on the left side of the front portion, the support frame body 31 and the frontmost partition body 26 A triangular plate-shaped closing body 37 is stretched around the enclosed portion to close the mesh formed between the front and rear extension rods 35 and 35 from above.
[0046]
In this way, when the cereal or drainage that begins to undergo threshing action on the start end side of the barrel body 13 is transferred onto the start end portion of the concave body 25 along the outer peripheral surface of the barrel body 13 Since the closing body 37 stretched on the left front facing the rotation direction of the barrel 13 is adapted to receive such cereals or waste, the cereals or waste are placed on the closing body 37. It does not slide and clog the mesh-like concave body 25.
[0047]
And since it is possible to prevent the cereal or waste from clogging in the concave body 25, it is possible to let the grain smoothly and surely leak through the concave body 25. It can also be discharged smoothly and reliably in the dust feeding direction.
[0048]
Moreover, at the position immediately below the concave 12, the first sorted air a flows from the front to the rear, and the first sorted air a is introduced into the barrel 11 side from the introduction body 14. It is possible to prevent the clogging from the lower side to the upper side by the closing body 37 so that the cereal can be smoothly and surely introduced from the introduction body 14 to the handling cylinder 11, and is reliably introduced into the handling cylinder 11. The first sorting wind a flows below the cereal after the cereal.
[0049]
FIG. 7 shows a dust handling tooth 21 as another embodiment, and the dust feeding tooth 21 is formed so that the outer shape of the peripheral end is substantially similar to the inner shape of the tooth handling 20. At the same time, the peripheral edge of the dust handling tooth 21 is brought into contact with the inner peripheral edge of the tooth handling 20 to eliminate the gap between them.
[0050]
In this way, it is possible to reliably prevent the grain handle and the heel portion of the tooth handle 20 from being caught, and the dust handling tooth 21 acts to deliver dust to the grain handle and the waste container, thereby eliminating the waste. It can be smoothly and reliably discharged in the dust feeding direction (the direction toward the waste disposal unit 7 along the axial direction of the barrel body 13).
[0051]
