Description

[Detailed description of the invention] Industrial application field The present invention relates to an exhaust dust treatment device for a threshing machine.
It is used in the field of threshing machines, which are agricultural machines.

Conventional technology Conventionally, a similar configuration has been implemented in a threshing machine in which a processing cylinder extending perpendicularly to the handling cylinder is mounted on the rear side of a swing sorting body extending from below the handling chamber. This can be seen in Publication No. 53-23668, but in this case, the material to be processed is sent from the processing cylinder side to the swinging sorter side, and is skillfully taken into the processing cylinder side from the swinging sorter side. It's not about the composition.

Problems to be Solved by the Invention This invention aims to smoothly take in a certain amount of material to be processed in the width direction of the oscillating sorting body from the oscillating sorting body without clogging the processing cylinder side. At the same time, it is possible to efficiently process such a large number of objects with the processing cylinder, and 3.
The purpose of the present invention is to provide a method that allows dust removal to be carried out reliably and favorably so as to reduce dust loss.

Means for Solving the Problem Next, a configuration example shown in the drawings will be described as a means for solving the problem.

Figure 3 shows a side sectional view of a threshing machine mounted on a combine harvester.A supply port 8 and a straw discharge port 9 are formed on both sides of a handling chamber 1 that houses a handling barrel 2, and a crimp is provided below the handling chamber 1. A net 10 is stretched, and a downward dust inlet 11 is formed at the terminal end of the net 10.
2. An oscillating sorting body A consisting of a grain sieve 13, a sieve wire 14, etc. is installed extending from the bottom of the handling chamber 1 to the rear, and a pressure fan 15 is mounted on a shaft below the starting end of the oscillating sorting body A. A No. 1 spiral conveyor 17 is mounted on the No. 1 gutter 16 installed horizontally below the grain sieve 13, and a suction dust removal chamber 18 is formed at the upper rear of the sieve line 14, which is the terminal end of the oscillating sorting body A. A suction port 20 of a suction dust ejector 19 is connected to one side of the suction device 19.

The sieve line 14 which becomes the terminal end side of the oscillating sorting body A
A No. 2 spiral conveyor 22 is mounted on the No. 2 gutter 21 installed horizontally below the processing chamber 2, and a processing chamber 2 installed horizontally above it.
A processing cylinder 3 having substantially the same length as the horizontal width of the oscillating sorting body A and perpendicular to the handling cylinder 2 is mounted in the processing chamber 3, and a concave 5 is stretched below the processing chamber 23. , the suction dust removal chamber 18 on the extension side of the sieve wire 14
An intake port 4 is opened above the processing cylinder 3, which is below the intake port 4, and one end of the processing cylinder 3 is low at the front upper part of the processing cylinder 3, which is in front of the intake port 4, and the other end is low. A guide plate 6 forming an upper edge 6a that is inclined so that the side A is higher is installed, and the width L between the upper edge 6a and the upper edge 6A is wide at one end and wide at the other end, as shown in FIG. The intake port 4 is formed so that the side ro is narrow, a plurality of lead plates 24 are attached to the back side of the processing chamber 23, and a dust exhaust port 7 is provided in communication with the lower side of the other end of the processing cylinder 3. and configure.

Therefore, during work, the workpiece that falls from the handling chamber 1 is shaken and sorted by the chaff sieve 12, and the first grains that leak from the grain sieve 13 and are screened fall into the first spiral conveyor 17. , 2 which is sent out from the chaff sieve 12 and leaks from the sieve line 14
The articles fall directly onto the No. 2 spiral conveyor 22, and the dust flowing toward the suction and dust removal chamber 18 is sucked into the suction and dust removal device 19 and discharged to the outside of the machine.

The processed material sent out from above the sieve line 14 flows to the intake port 4 as shown by arrow C, and is taken into the rotating processing cylinder 3 as shown by arrow D, but as shown by arrow T. When the amount of material to be sorted increases on one side of the oscillating sorting body A due to the wind generated by the rotating handling cylinder 2, large amounts of material are taken in with a wide opening as shown by the arrow H. A small amount of material flows toward the intake port 4, which has a narrow opening, as shown by the arrow, and is taken in therein.

In this state, the object to be processed is transferred from one end (a) of the processing cylinder 3 to the other end (b), but since the intake port 4 is narrower near the other end (b), After being sufficiently processed in the processing chamber 23, the second material leaks from the concave 5 and falls into the second spiral conveyor 22, and the waste material is discharged from the other end to the dust outlet 7. will be done.

Effects of the invention As described above, the present invention provides a threshing machine in which the processing cylinder 3 extending perpendicularly to the handling cylinder 2 is mounted on the rear side of the swing sorting body A extending from the lower side of the handling chamber 1. , the upper side of the processing cylinder 3, which is formed to have approximately the same length as the width of the oscillating sorter A, is open as an intake port 4, and a concave 5 is provided on the lower side;
A guide plate 6 with an inclined upper edge 6a is installed at the front upper part of the processing cylinder 3 so that the intake port 4 at one end A of the processing cylinder 3 is wide and the other end B is narrow. Since the dust exhaust port 7 is connected and connected to the lower part of the other end of 3, a certain amount of material to be processed in the width direction of the oscillating sorting body A can be directly taken in from the oscillating sorting body A through the inlet. 4 to the processing cylinder 3 to avoid clogging.
This means that the processing cylinder 3 can be taken in smoothly, and the partition of the guide plate 6 that forms the intake port 4 makes the processing cylinder 3 narrower on the other end side.
The processing action is performed efficiently and sufficiently near the other end, and the dust removal processing can be performed reliably and satisfactorily so as to reduce the third loss, and has the feature that it can be carried out suitably with a simple structure.
