Description

[Detailed Description of the Invention] The present invention relates to a second processing device in a threshing machine.

That is, in the same way as in the past, the second material that is sorted and dropped from the oscillating sorter is processed by the processing cylinder, straw waste, etc. is discharged from the machine, and the second material containing grains that has been processed by the processing cylinder is removed. This allows the straw to be accepted into the No. 2 spiral conveyor and returned to the No. 2 spiral conveyor, making it possible to process the No. 2 waste more efficiently and eliminating the need to return a lot of straw waste and result in poor sorting, unlike in the conventional method. The purpose of the present invention is to provide a well-balanced processing function and structure that can be carried out suitably, eliminating clogging of various parts and increasing the power load of each part.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a sectional view of a threshing machine mounted on a combine harvester, in which a supply port 7 and a straw discharge port 8 are installed on both sides of the lower part of a handling chamber 6 that houses a handling barrel 5 with handling teeth.
A crimp net 9 is stretched in the lower part of the handling chamber 6, and a downward dust inlet 10 is installed at the end of the crimp net 9.
The rear part of the machine is equipped with a sorting dust chamber 13 having a dust exhaust port 11 connected to the rear and a suction port 12 of a suction dust exhauster connected to the upper side, and is constructed in the same manner as the conventional structure.

In addition, from the lower part of the handling chamber 6 to the lower part of the sorting and dust removal chamber 13, there is a feed pan, a chaff sieve 15,
A swinging sorting body A consisting of a Glensieve 16 and a stroke rack 17 is extended, and a pressure fan 18 is installed below one end of the swinging sorting body A. 1 for gutter 19
A No. 1 return pan 22 diagonally installed from the rocking sorter A is installed facing the No. 1 return pan 22 on which the No. 1 spiral conveyor 20 is mounted, and which extends from the No. 1 gutter 19 diagonally rearward and upper. The structure is similar to the conventional structure.

A funnel-shaped No. 2 return pan 23 whose lower end opening 23a is biased to one side is integrally installed vertically at the lower end of the swinging sorter A, which is below the stroke rack 17. A No. 2 spiral conveyor 2 is mounted on the No. 2 gutter 2a installed horizontally in the lower part of the machine, and a jump fan 24 is installed at one end of the No. 2 spiral conveyor 2 on the outside of the machine. A No. 2 thrower 1 is installed in communication with the inside, and the No. 2 thrower 1 is installed so as to be able to return the No. 2 to the handling room 6, etc.

Above the No. 2 spiral conveyor 2, a processing cylinder 3 having a large number of processing teeth 3a implanted on its outer peripheral surface is rotatably mounted parallel to the No. 2 spiral conveyor 2.
A concave 25 is installed around the lower part of the processing cylinder 3 above the No. 2 spiral conveyor 2, and the concave 25 is installed above the processing cylinder 3 so as to open the upper side where the mouth 23a of the No. 2 return pan 23 looks. A wall plate 26 is stretched, and several spiral reed plates 27 are fixed to the wall plate 26.
The second spiral conveyor 2 is installed in the opposite direction to the feeding direction, and the outside of the machine opposite to the second thrower 1 is connected to the other end of the processing cylinder 3. A dust removal fan cylinder 4 having a fan 28 installed therein is arranged in series, and the second object is dropped from the second return pan 23 above one side of the processing cylinder 3 opposite to the side of the dust removal fan cylinder 4. be installed and configured so that it can be accessed.

Further, a hammer chopper 29 is installed in a part of the processing cylinder 3, a transmission pulley 30 is installed on the outside of the dust removal fan cylinder 4, and a No. 2 spiral conveyor 2 is installed below the transmission pulley 30. transmission pulley 3
1 are each mounted on an axis.

With each part operating and work being carried out in the same manner as before, the second item that is sorted by the oscillating sorter A and falls from the stroke rack 17 is transferred from the second return pan 23 to the processing cylinder 3 side. When you fall,
The water is circulated by the rotating processing cylinder 3 as shown by arrow A, and the processing teeth 3a and concave 25
Due to the synergistic action of these, twig stalks such as grains fall into the lower No. 2 spiral conveyor 2, are conveyed as they are in the direction of arrow B, and are returned and reprocessed by the No. 2 thrower 1. The straw waste and the like are sent in the direction of arrow C while circulating around the processing cylinder 3, and are discharged from the dust removal fan cylinder 4 to the outside of the machine.

In this way, the present invention is capable of dropping grains, etc. above the No. 2 spiral conveyor, which has a No. 2 thrower connected to one end, and at the same time, it is possible to drop straw waste, etc. in the opposite direction to the No. 2 spiral conveyor. A processing cylinder that can be fed is mounted on parallel shafts, a dust removal fan cylinder is connected to the other end of the processing cylinder opposite to the second thrower, and a second object is mounted above the processing cylinder. Since it is configured so that a part of the oscillating sorting body that sorts and falls is visible, the second material falling from the oscillating sorting body is crushed by the processing cylinder, and the second material such as grains is crushed in the lower part. While being sent out by the No. 2 spiral conveyor, straw waste can be discharged from the dust removal fan body to the outside of the machine. Processing can be carried out efficiently, eliminating the conventional problems of reducing a large number of secondary materials, resulting in poor sorting, clogging in various parts, and increasing the power load of each part, and reducing the feed of the processing cylinder. By reversing the feed of the No. 2 spiral conveyor, processing performance is improved, and the structure has a balanced structure that allows for suitable implementation.
