DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tooth handling mounting structure for a threshing apparatus in which a large number of independent teeth are mounted on the outer peripheral surface of a handling cylinder.

[0002]

2. Description of the Related Art Conventionally, independent teeth have been formed separately from each other and bolted to a handle cylinder separately.

[0003]

However, in order to bolt a large number of independent teeth formed separately from each other to the handle cylinder, it takes a lot of trouble and time to assemble the teeth. There was room for improvement in terms of improving the workability of assembling the teeth. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to efficiently perform a tooth handling assembling operation, and to easily and reliably realize strong tooth handling fixing.

[0004]

A feature of the present invention is that in a threshing apparatus in which a large number of independent teeth are mounted on the outer peripheral surface of a handling cylinder, a plurality of the independent teeth are arranged in the direction of the rotation axis of the handling cylinder. were fixed on a single mounting plate, said mounting plate
Bend at one point in the circumferential direction of the handling cylinder.
More specifically, the mounting surface is bent so as to be in contact with the outer peripheral surface of the handling cylinder at two contact portions in the circumferential direction, and the tightening bolt for fixing the mounting plate to the handling cylinder is connected to the both ends.
The contact between the contact portions and on the side farthest from the bending point
That is, it is arranged on a flat portion having a touch portion .

[0005]

[Operation] In other words, if one mounting plate is fixed to the handle cylinder, a plurality of independent teeth can be mounted, so that the number of man-hours required for assembling the teeth can be reduced to a fraction of that in the prior art. In addition, the tooth handling assembling work can be efficiently executed. Moreover,
The bent mounting surface of the mounting plate is brought into contact with the outer peripheral surface of the handling cylinder at two locations in the circumferential direction, and the mounting plate is fixed to the handling cylinder with the tightening bolts between both contact parts, so that the powerful fixing state of the independent teeth is easy. It can appear reliably.

[0006]

As a result, a tooth handling mounting structure for a threshing apparatus with further improved assembling operability, which can improve the efficiency of the tooth handling assembling operation and can easily and reliably realize strong tooth handling fixing, is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a hydraulic cylinder 3 is used to support a fulcrum P at the front of a traveling vehicle body equipped with a crawler-type traveling device 1.
The mowing part 2 is connected to the surroundings so as to be able to swing up and down, and a threshing device 7 and a grain tank 1 for collecting the first item are mounted on the traveling vehicle body.
1, the boarding operation section 12, etc., and the reaping section 2
Is provided with a planting grain stalk elevating device 5, a cutting blade 6, a vertical conveying device 8 for feeding the harvested grain stalk rearward and upward, and a threshing device 7
A feed chain 9 is provided at the side of the feeder 9 to pinch the cereal culm from the vertical conveying device 8 in a laterally inclined posture, convey it rearward, and supply it to the threshing device 7 to constitute a self-removing combine.

[0008] As shown in FIG.
Is rotatably supported about the front and rear horizontal axis, and
A receiving net 15 is provided between the sorting unit 10 and the sorting unit 10, and the swinging sorting case 16, the Karin 17 for wind selection, the screw conveyor 18 for collecting the first item, and the screw conveyor 1 for collecting the second item
9 and the like, and the processed material leaked from the receiving net 15 and the processed material discharged from the end of the handling room 13 are rocked and sorted.
While oscillating and transferring backwards, the sieving sorting and air sorting processing is performed, and the grains collected by the screw conveyor 18 for collecting the first product are sent to the Glen tank 11 and the sorting is performed by the screw conveyor 19 for collecting the second product. Insufficient second product is configured to be sent to the front of the swing sorting case 16 by the reduction device 4.

[0009] A large number of independent teeth 20, 21, 22
4 is attached to the outer peripheral surface, and the independent teeth 20, 21, and 22 are located at the front end side in the grain culm transport direction, 20 is a regularized tooth for combing and aligning the supply grain culm, and 21 located in the middle is main threshing. A tooth 22 to be processed and a tooth 22 located at the rear end side are formed in a tooth to be subjected to final grain shedding.

As shown in FIGS. 3 and 4, a plurality of independent teeth 22 which are arranged as processing teeth and are arranged in the direction of the axis of rotation of the handling cylinder 14 are fixed to one mounting plate 23 by welding or integral casting. The mounting surface of the mounting plate 23 is bent so as to be in contact with the outer peripheral surface of the handling cylinder at two contact portions 24a and 24b in the circumferential direction, and the tightening bolts 25 for fixing the mounting plate 23 to the handling cylinder 14 are connected to both contact portions 24a. , 24b. That is, one mounting plate 23 is
4, a plurality of independent teeth 22 can be attached, and the number of teeth assembly steps can be greatly reduced.
Further, the bent mounting surface of the mounting plate 23 is brought into contact with the outer peripheral surface of the handling cylinder at two locations in the circumferential direction, so that the two contact portions 24a and 24
The mounting plate 23 is fixed to the handling cylinder 14 without loosening with the tightening bolts 25 between the 4b, and the independent handling teeth 22 can be strongly and easily and securely fixed.

As shown in FIGS. 5 and 6, in order to form the independent teeth 21 as the parallel teeth, the thin plate-like teeth 21a, the thick teeth peripheral edges 21b, and the mounting seat 21c are integrally forged, and the mounting seat 21c is formed. A bolt wear preventing member / reinforcing rib 21d is integrally formed with 21c, so that it is easy to manufacture, easy to replace, and has sufficient strength.

[Alternative Embodiment] The setting range of the tooth handling in which the independent teeth 22 arranged in the direction of the rotation axis of the handling cylinder are fixed to one mounting plate 23 can be appropriately selected. May be out of phase in the circumferential direction of the handling cylinder. In order to form the independent teeth 21 as the parallel teeth, as shown in FIG. 7, a sheet metal processed product or a cast product integrally provided with a plate-shaped tooth portion 21e and a mounting seat 21f may be used to simplify the production. Good.
