Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention uses a Glen pan that receives and processes the objects to be sorted leaked from the handling chamber to the sorting unit in a state where the objects to be sorted are conveyed in the direction of the axis of rotation of the handling barrel main body along with the swing. A conveyor for second product reduction is provided to return the second product from the sorting section to the Glen pan. The discharge port of the conveyor for second product reduction is located on one side of the Glen pan, and the discharge direction from the discharge port is handled. The present invention relates to a threshing device which is arranged in a state opposite to the rotating direction of the lower part of the body.

[0002]

[Prior Art]

 Conventionally, the grain pan in the threshing device has been formed in a horizontal shape in the left-right direction as shown in, for example, Japanese Utility Model Publication No. 3-50834.

[0003]

[Problems to be solved by the device]

 However, in addition to providing a Glen pan that receives and processes the objects to be sorted leaked from the handling chamber in a state in which the objects to be sorted are conveyed in the direction of the axis of rotation of the handling barrel main body with the swing, Since the discharge port of the conveyor for second material reduction is arranged laterally to one side of the Glen pan so that the discharge direction from the discharge port is opposite to the rotation direction of the lower part of the handling cylinder body, As shown in FIG. 7, the Glen pan 13 is laterally biased to one side due to the rotation of the handling body 5 from the handling chamber 2 and is laterally moved from the conveyor 10 due to the arrangement of the discharge port 10a. The material to be sorted is biased to the other side, and the distribution of the material to be sorted to the Glen pan 13 is biased to the lateral side where the sorting efficiency is low, and it tends to be uneven in the left and right direction of the Glen pan 13, which improves sorting performance. There was room for improvement. An object of the present invention is to improve the sorting performance by making it possible to evenly distribute the objects to be sorted on the Glen pan in the left and right directions by simply modifying the Glen Pan.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention is that the grain pan that receives and processes the objects to be sorted leaked from the handling chamber is conveyed in the direction of the axis of rotation of the handling barrel main body as the swings. It is installed in the sorting section in the state, and the second item reducing conveyor for returning the second item from the sorting section to the Glen pan is provided, and the discharge port of the No. 2 item reducing conveyor is located on one side of the Glen pan and from the discharge port. In the threshing device that was placed in a state where the discharge direction of the grain was opposite to the rotation direction of the lower part of the main body, at least both lateral parts of the Glenpan were formed on an inclined surface that became lower toward the center.

[0005]

[Action]

 In other words, the objects to be sorted, which are fed from the handling room and the conveyor for returning the second product to the Glen pan in a state of being biased to the left and right, are conveyed by the swinging of the Glen pan, and by the action of the inclined surfaces on both lateral sides of the Glen pan, the Glen pan is operated. It can be moved to the center of the left and right, and the distribution of the objects to be sorted on the Glenpan can be equalized in the left and right directions, and the sorting performance can be sufficiently improved. Moreover, it is sufficient to make a simple modification such that both lateral portions of the Glen pan are formed into inclined surfaces that become lower toward the center, so that cost increase can be sufficiently suppressed.

[0006]

[Effect of the device]

 As a result, it has become possible to provide a more excellent threshing device capable of improving the sorting performance while sufficiently suppressing the cost increase.

【Example】

 To construct an axial flow type threshing device for all culm input type combine harvesters, as shown in Fig. 1, a handling room 2 communicating with a feed conveyor 1 for feeding grain culms from the mowing section is formed in the upper part of the case and handled. A sorting unit 3 is arranged below the chamber 2, and a receiving net 4 is provided for feeding grains from the handling chamber 2 to the sorting unit 3 in a leaky manner.

The handling cylinder main body 5 is mounted in the handling chamber 2 by a front and rear driving rotary shaft, and the spiral handling teeth 6 are attached to the outer peripheral surface of the handling cylinder main body 5 over the entire length and in a concentric manner. In order to form the above, a large number of handling teeth 6b are attached to the tip side of the screw 6a at appropriate intervals, and as the handle body 5 is driven and rotated, the spiral handling teeth 6 act to thresh the culm. It is configured to be transferred to the rear.

The sorting unit 3 is provided with a swing sorting means 3 a, a wind-picking Karasu 3b, a No. 1 product recovery screw conveyor 7, and a No. 2 product reduction screw conveyor 8 to drop grains supplied from a receiving net 4. The grains are processed by the oscillating sorting unit 3a, the grains dropped and supplied from the oscillating sorting unit 3a are subjected to the wind sorting process by the action of the Kara Minoh 3b, and the dehulled grains are sent from the No. 1 recovery screw conveyor 7 to the Glen tank. It is configured such that the poorly sorted No. 2 product is returned from the No. 2 product reducing screw conveyor 8 to the Glen pan 9 of the swing selecting means 3a by the bucket conveyor 10.

As shown in FIG. 2, the discharge port 10 a of the bucket conveyor 10 is located laterally of the Glen pan 9, and the discharge direction from the discharge port 10 a is opposite to the rotation direction of the lower portion of the handling cylinder body 5. In this state, the Glen pan 9 is formed in a bent shape in which the left and right center sides are lowered, and the workpieces that are biased left and right from the handling chamber 2 and the discharge port 10a to the Glen pan 9 are conveyed along with the swing of the Glen pan 9. At the same time, the slanted surface of the Glen pan 9 moves to the center of the left and right sides so that the distribution of the objects to be sorted on the Glen pan 9 is equalized in the left and right direction.

To form the bucket conveyor 10, as shown in FIGS. 3 and 4, a perforated plate 11 having a long hole having a size that prevents passage of soybeans and allows passage of mud is provided at the bottom of the conveyor case 10c. And a resin-made star wheel type blade 12b attached to the support shaft 12a, the blade wheel 12 is attached to the perforated plate 11 with the blade 12b inserted into the elongated hole 11a, and is driven and rotated by the bucket 10b. When the soybean is harvested, the mud in the conveyor case 10c is reliably scraped out by the blade 12b when the soybean is harvested. The perforated plate 11 is replaceably attached to the blind plate so that the combine can be applied to fine grains such as rice and wheat.

[Other Embodiments] Instead of the bucket conveyor 10, a conveying means such as a screw conveyor may be provided, and they are collectively referred to as a No. 2 reduction conveyor 10.

For example, as shown in FIG. 5, the shape of the Glen pan 9 may be a bent shape in which the central portion 9a is horizontal in the left-right direction and both lateral sides 9b and 9c are inclined surfaces that become lower toward the central side. As shown in FIG. 6, the shape may be a smoothly curved shape such that it becomes lower toward the left and right center sides. In short, at least both lateral side portions of the Glen pan 9 may be formed on an inclined surface that becomes lower toward the center side.

The present invention can also be applied to a dedicated threshing machine.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
