Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing drum chamber structure of a threshing unit of a combine which opens a processing drum chamber communicating with a handling drum chamber and facilitates maintenance.

[0002]

2. Description of the Related Art Conventionally, in a threshing section of a combine which is constructed by mounting a processing cylinder in a processing cylinder chamber whose leading end communicates with an end portion of a handling cylinder chamber and extends rearward of the machine body, the processing cylinder chamber has A net is stretched on the inner peripheral side so that grains and the like processed by the processing drum in the processing drum chamber leak from the net and are processed.

[0003]

However, the processing chamber is easily clogged, and when it becomes clogged, it is difficult to open the processing chamber because it is necessary to clean the processing chamber. In addition, the maintenance of the processing teeth of the processing cylinder and the like is also troublesome and difficult, and the maintenance of the processing of the net and the processing teeth of the processing cylinder is also troublesome and difficult. I have.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such a problem and to make it simple and suitable for implementation. Therefore, the outer peripheral surfaces of the processing chamber chambers are respectively curved in an arc shape. The inner frame portion and the outer wall portion are divided into two, and both the frame members at both ends in the circumferential direction of the net frame portion and the two flanges at both ends in the circumferential direction of the outer wall portion are vertically connected. In addition to being detachably fixed to the machine body frame, the screen frame is configured to be able to be taken out while rotating along the outer periphery of the processing cylinder.

[0005]

Therefore, if the processing chamber is clogged, if both flanges of the outer wall are removed from the upper and lower body frames, the processing chamber can be opened to remove the clogged one. In addition to being able to remove and clean, the maintenance of the handling teeth and the like of the processing cylinder can be easily performed.In addition, both frames of the mesh frame are separated from the upper and lower body frames, and the mesh frame is directly processed by the processing cylinder. When the wire frame is pulled out while being rotated along the outer periphery of the web, the net frame portion can be easily removed, and the net can be easily maintained.

FIG. 2 is a plan sectional view of a threshing unit mounted on a combine, with a part of the threshing unit omitted. A feed chain 8 and the like are provided outside a handling cylinder room 1 in which a handling cylinder 7 is incorporated.
A straw chain 10 is provided above the sorting / dusting chamber 9 on the rear side of the body of the handling chamber 1, and a processing chamber 2 whose starting end communicates with a dust outlet 11 on the rear side of the end of the handling chamber 1. It extends parallel to the handling cylinder 7 and extends to the rear side of the machine body. A dust outlet 12 is formed below the terminal end of the processing cylinder chamber 2, and a screw 13 and a handling tooth 14 are provided in the processing cylinder chamber 2. The processing cylinder 3, which rotates as shown by the arrow B in the same direction as the rotation direction A of the handling cylinder 7, is constructed like a conventional structure by axle mounting.
FIG. 3 shows a swing sorting body extending from the lower part of the handling body chamber 1 to the sorting and dusting chamber 9 side.

The processing chamber 2 is formed into a cylindrical shape, and its outer peripheral surface is divided into an inner net frame portion 4 and an outer outer wall portion 5 each of which is curved into a semi-cylindrical shape. A net 16 is stretched on the peripheral surface of the frame 4 and an inlet 17 is formed at the start end side. , 4b, and each cutting blade 18 is fixed to an inner portion of the lower frame 4b facing the toothing 14, and a guide valve 19 is provided on the inner peripheral surface of the outer wall 5. And flanges 5a and 5b are formed at both ends in the circumferential direction of the outer wall portion 5 so as to be bent and extended in the radial direction, respectively, so that an upper body frame portion 6a, the frame body 4a and the flange 5a are formed. Each mounting screw 20 is attached to the lower frame 6b, the frame 4b, and the flange 5b. 21 respectively constitute detachably and inserted.

Therefore, as shown in FIGS. 1 and 3, the frame body 4a and the flange 5a are overlapped on the outer side of the upper body frame part 6a, and the respective mounting screws 20 are inserted. The frame 4b and the flange 5b are respectively fitted inside and outside, and the mounting screws 21 are inserted.
If the processing chamber 2 is clogged during operation, the mounting screws 20 and 21 are removed, and as shown in FIGS. 4 and 5, the outer wall 5 is removed. The body chamber 2 can be opened widely, so that clogged objects can be removed and cleaned, and maintenance of the teeth 14 of the processing cylinder 3 can be easily performed. Frame 4a
And pulling it out in the direction of arrow C, in a direction opposite to the rotation direction B of the processing cylinder 3, from above to below along the outer circumference of the processing cylinder 3.
The Amiwaku portion 4 while selfish rotated so that can be drawn outwardly, as shown in FIGS. 6 and 7, will be able to retrieve it, the maintenance network 16 can be easily performed.

[0009]

As described above, according to the present invention, when the processing chamber 2 is clogged, the flanges 5a, 5a, 5a, 5
When b is removed from the upper and lower machine frames 6a and 6b, the processing drum chamber 2 can be opened, so that the clogged object can be removed or easily cleaned, and the processing teeth 3 of the processing drum 3 can be removed. Maintenance can be easily performed, and both frames 4a and 4b of the net frame 4 are separated from the upper and lower body frames 6a and 6b, and the net frame 4 is moved along the outer periphery of the processing drum 3 as it is. By pulling out while rotating, the net frame portion 4 can be easily removed, so that maintenance of the net can be easily performed, and such cleaning and maintenance can be effectively performed with good workability. It has a feature that it can be carried out and can be suitably implemented by a simple structure having sufficient strength. And especially
While rotating the upper frame 4a from above to below,
Can be removed to the outside, so inspection work
The person turns his weight while hanging it on the upper frame 4a.
Can perform unloading work and maintenance work without using unnecessary force
Has the effect that it can be performed easily.
