Description

[Detailed explanation of the idea] The present invention relates to a sorting device in a threshing machine.

That is, a swinging sorting room is provided below the handling barrel room in which sorting air flows in the same direction as the axis of the handling barrel, and a processing barrel chamber for processing the unprocessed materials in the handling barrel room is placed in the handling barrel room. In the case where they are installed side by side, a discharge port is provided on the discharge side of the handling barrel chamber and the processing barrel chamber, respectively, and a rocking plate installed in the rocking sorting chamber is provided below the processing barrel via a grain board. In order to communicate with the upper side of one side of the dynamic sorting body, the lower part of the discharge port of the processing barrel is located in the middle of the swinging sorting unit, and each rod of the swinging sorting body faces in the direction of inclination of the grain board. The decorative edge is arranged diagonally, and the decorative edge is made to swing together with the swinging sorting body, and the mixture of grains and straw waste discharged from the discharge port of the processing barrel can be shaken and sorted. It is fed to the middle part of the body and is sorted together with the grains and culm pieces scattered from the discharge port of the handling barrel chamber, and in the process of transferring to the oscillating sorting body, the grains are separated by the decorative edge. It is an object of the present invention to provide a sorting device for a thresher which aims to simplify the structure by separating straw waste and contribute to improving the sorting throughput.

The embodiments shown in the drawings will be described below.

FIG. 1 shows a sectional view of the threshing machine, in which a handling barrel 1a is mounted on a shaft in a handling barrel chamber 1 communicating with a supply port 5, and a crimp net 6 is installed around the lower part of the threshing machine.
A discharge port 8 partitioned by a partition plate 7 is formed downward on the discharge side 1b of the handling barrel chamber 1, which is covered with dust, and the sorting air is directed from below the crimp net 6 to the dust removal chamber 9 at the rear of the machine along the axis of the handling barrel 1a. A swinging sorting room R that blows air in the same direction as the core direction is provided, and in this swinging sorting room R, a grain feeding plate 10, a sorting plate 11 . A swinging sorting body A consisting of a sorting net 12, a stroke rack 13, etc. is installed, and below it a number 1 conveyor 15 is installed.
．． A No. 2 conveyor 16 is provided respectively, and a dust suction device 17 is installed on the lower rear side.

Further, a foot chain 18 and a clamping rod are installed above and below the handling barrel chamber 1, and a straw discharge port 19 is formed at the rear of the handling barrel chamber 1.

Reference numeral 2 denotes a processing barrel chamber arranged parallel to the processing barrel chamber 1, in which a processing barrel 2a parallel to the processing barrel 1a is mounted on a shaft;
The discharge side 1b on which the crimp net 20 is stretched is formed by partitioning the downward discharge port 3 with a partition plate 21, and the second conveyor 16
The jump upper part 23 of the No. 2 thrower 22 connected to the terminal end of the processing barrel 2 is connected to the end of the processing barrel 2, and the lower part of the discharge port 3 from the crimp net 20 is connected to one side of the swing sorting body A. A grain flow plate 24 is installed diagonally upward and communicates with the top of the oscillating sorting body A, and the lower part of the discharge port 3 is located in the middle of the oscillating sorting body A in the front and back direction. Install it.

In addition, a large number of node lines 4 are installed on the side of the swinging sorter A from the lower side of the slope of the grain flow board 24 to the upper side of the swinging sorter A on the lower side of the discharge port 3, but all the rods 4a are installed on the side of the swinging sorter A. One end side of the support plate 26 fixed to the mounting plate 25 to be attached is fixed to the one side plate 27 of the swing sorting body A with a bolt nut 28, and each rod 4a is installed diagonally so as to face in the direction of inclination of the grain board 24.

Therefore, in the threshing work, the handling drum 1a is
When threshing is performed and the grains are oscillatedly sorted by the oscillating sorter A, the first grains fall onto the No. 1 conveyor 15, the unprocessed grains fall onto the No. 2 conveyor 16, and the waste material is collected by the dust collector. It is ejected from the machine by machine 17.

Therefore, the unprocessed material that falls onto the No. 2 conveyor 16 and is transferred is thrown up into the processing barrel chamber 2 by the No. 2 thrower 22 and is processed as it is by the processing barrel 2a, and the grains leak through the crimp net 20. The grains, straw waste, etc. that are discharged from the discharge port 3 are collected from the grain flow board 24-H for decoration. The straw waste flowing on the edge 4 is moderately sieved and fractionated by the nodal line 4 which oscillates with the same amplitude as the oscillating sorter A, and the straw waste on the decorative rim 4 is guided toward the rear of the oscillating sorter A and falls. People will be subjected to shaking selection.

In this way, the present invention provides a swinging sorting chamber in which the sorting air flows in the same direction as the axis of the handling barrel below the handling barrel, and a processing barrel for processing the unprocessed materials in the handling barrel. In parallel with the handling barrel chamber, an outlet is provided on the discharge side of the handling barrel chamber and the processing barrel chamber, respectively, and the lower part of the separate processing chamber is installed in the swinging sorting chamber via a grain board. In order to communicate with the upper side of one side of the oscillating sorting body, the lower part of the discharge port of the processing barrel is located in the middle of the oscillating sorting body, so that the process material leaking from the processing barrel and the discharge port are There is no need to install a separate sorting unit to separate the mixture of grains and straw waste discharged from the processing barrel, and the oscillating sorter handles it together with the material leaking or being discharged from the handling barrel. Although the structure is extremely simple, the mixed material discharged from the discharge port of the processing barrel is in the process of sorting on the oscillating sorter, and is in almost the same sorting state as this mixed material. As a result, rational sorting can be performed without adversely affecting the oscillating sorting action.

In addition, each rod has a node line diagonally arranged in the direction of inclination of the grain plate on the side of the swinging sorter at a location below the discharge port of the processing barrel and communicating with the top of the swinging sorter. The nodal line oscillates together with the oscillating sorter and separates grains and straw waste in the process of transitioning from the flowing grain plate to the oscillating sorter, improving the sorting throughput on the oscillating sorter. I was able to obtain it.
