Description

[Detailed Description of the Invention] The present invention relates to an exhaust dust treatment device for a threshing machine.

In other words, the dust etc. discharged from the handling chamber can be sent to the processing barrel by the oscillating sorter, and the processing barrel can take in the waste while processing and discharging the dust. The dust can be conveyed well by preventing the dust from getting stuck to the front end of the receiving net, and the dust can be sorted and processed reliably and smoothly, improving threshing performance. The object of the present invention is to provide a simple structure that can be improved and suitably implemented.

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

Fig. 1 shows a side sectional view of a threshing machine mounted on a combine harvester, in which a supply port 1 is located at the front and rear of the lower part of a handling chamber 1 in which a handling barrel 10 rotated by a handling barrel shaft 4 is installed.
1 and a straw discharge port 12, a crimp net 13 is stretched on the lower side of the handling chamber 1, and a downward dust feed port 14 is installed at the end approaching the straw discharge port 12. A straw removal chain 16 is installed above the No. 4 gutter plate 15, which is installed diagonally from the outside of the straw removal port 12 to the rear upper part, to remove the straw inherited from the feed chain on the outside of the handling room 1. It is installed so that it can be carried out to the rear of the fuselage using a chain 16, and has the same structure as the conventional structure.

A processing barrel chamber 3 is installed below the fourth gutter plate 15, and a receiving net 2 having an arc-shaped side surface is stretched around the lower side of the processing barrel chamber 3, and the front end of the receiving net 2 An opening 7 that opens in the direction of the dust inlet 14 is formed in the front part of the processing barrel chamber 3 above A, and the upper part of the rubber sag 8 is fixed to the front end A of the receiving net 2 with a stopper 17. In the rear part of the processing barrel chamber 3, a straw discharge port 18 is installed at the rear lower part to communicate with a fan case 19 in which a cross-flow fan type suction dust extractor 9 is installed. A processing cylinder 6 having a large number of processing teeth 5 implanted on its outer peripheral surface is mounted perpendicularly to the processing cylinder shaft 4 within the processing cylinder 3, and is rotatable so that the processing teeth 5 extend downward into the opening 7. Configure.

From the bottom to the rear of the handling room 1, there are a feed pan 20, a chaf sieve 21, a grain sieve 2
The swinging sorter A equipped with a second etc. is extended so that the rear parts of both side plates 23 of the swinging sorter A extend to both sides below the receiving net 2, and behind the chaff sheave 21. A group of sieve lines 24 is extended from the terminal end of the oscillating sorting body A toward the lower side of the opening 7 of the processing barrel 3, and both sides of the rubber sag 8 are connected to the side plates 23 of the oscillating sorting body A. It is installed and configured so that it comes into contact with the

In addition, a pressure fan 2 is provided on the lower side of the oscillating sorter A.
A No. 5 and No. 1 spiral conveyor 26 are arranged, and a No. 2 spiral conveyor 27 is arranged below the sieve wire 24 and the receiving screen 2, and the lower part of the receiving screen 2 communicates with the suction dust ejector 9 side. Install and configure it as follows.

During the threshing operation, the material to be sorted leaking from the crimp net 13 and the waste material falling from the dust inlet 14 are separated by the chaff sieve 21.
The grains leaking from the grain sieve 22 are screened and fall into the No. 1 spiral conveyor 26, and the waste sent out from the chaff sieve 21 is shaken and sorted by the sieve wire 24, and the second grains are passed through the lower No. 2 spiral conveyor. Dust and the like that fall onto the conveyor 27 and are sent out from above the sieving line 24 as shown by arrow B are taken into the processing barrel chamber 3 by the processing teeth 5 of the processing cylinder 6 that rotates as shown by arrow C. The grains, etc. that are processed while being stirred in the processing barrel chamber 3 and leaked from the receiving net 2 are sorted out by the suction air from the suction dust extractor 9.
The dust that falls into the number spiral conveyor 27 and is discharged from the rear of the processing barrel chamber 3 remains as it is by the suction dust extractor 9.
will be sucked in and ejected from the machine.

In that case, since the rubber sag 8 is attached to the front end A of the receiving screen 2, the dust etc. sent out from the sieve wire 24 and taken in by the processing teeth 5 will not get stuck on the front end A side. will be prevented, and
Dust and the like are screened out by the rubber sag 8 that comes into contact with the side plate 23 of the oscillating sorter A and vibrates.

In this way, the present invention is equipped with a processing barrel chamber 3 on the rear side of the terminal end of the swing sorting body A extending from the lower part of the processing chamber 1 to the dust removal side. At the same time, a processing cylinder 6 is rotatably mounted in the processing cylinder chamber 3 in an axial direction perpendicular to the processing cylinder axis 4,
At the front end part A of the receiving net 2 at the lower part of the opening 7 in the front part of the processing barrel 3, which is close to the terminal end side of the oscillating sorting body A, both sides are brought into contact with both side plates 23 of the oscillating sorting body A. Attach the rubber sag 8 that has been
Since the suction dust ejector 9 is connected in communication with the rear side of the housing, the dust etc. discharged from the handling chamber 1 are sent out to the processing barrel chamber 3 side by the oscillating sorter A, and are then removed by the processing teeth 5. The dust can be taken in well, processed by the processing cylinder 6, and removed by the suction dust extractor 9, and furthermore, it is processed by attaching the rubber drips 8 whose both sides are in contact with the side plates 23 of the oscillating sorter A. The dust taken into the barrel chamber 3 can be transported well without being caught by the front end A of the receiving net 2, and the dust sent out from the swinging sorter A is not caught or stagnates. The present invention has the feature that it can reliably and smoothly sort out and dispose of waste without clogging or clogging, improve threshing performance, and can be suitably implemented with a simple structure.
