Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing machine, and in particular, it is equipped with a pot-hole type rotary sorting barrel in place of the conventional oscillating sorting body, and is capable of selecting the first grain with good sorting performance, and in addition, it is capable of eliminating vibration. The rotary sorting cylinder is mounted on the upper side in a small state, so that the flow of the objects to be sorted is improved and the overall height of the machine body is not increased, so that it can be suitably implemented.

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 handling chamber 2 has a built-in handling barrel 1 and a feed chain 13 and a trapping rod 14 are installed on the outside. Forming a straw opening 16,
A grain grain board 18 is provided diagonally below the crimp net 17 stretched at the bottom of the handling room 2, and a sorting rack 3 from a winnowing machine 19 is extended below the grain grain board 18. A No. 1 conveyor gutter 4 on which a spiral conveyor 5 is mounted is installed horizontally, and a sorting plate 20 is installed rearward from the bottom of the terminal end of the handling chamber, and a sorting plate 20 is placed below the sorting plate 20 on the extension side of the sorting style 3. Harusen conveyor 8
A No. 2 conveyor gutter 7 equipped with a shaft is provided horizontally, and the terminal end of the No. 2 conveyor gutter 7 and the handling chamber 2 are communicated via the No. 2 thrower 6, and the upper part of the rear part of the sorting plate 20 is provided. An axial flow fan 21 is mounted on the shaft, and a third port 22 is installed behind it.

Further, a case 23 is connected to the side of the handling chamber 2, and inside the case 23 is a cylindrical rotary sorting cylinder 11 with both ends open and a large number of pot holes 10 formed on the inner peripheral surface.
The rotary sorting cylinder 11 is provided with driving wheels 24 in contact with the lower ends of the rotary sorting cylinder 11, respectively, so that the rotary sorting cylinder 11 is rotationally driven by the driving wheels 24, and is installed on the side of the case 23. The above-mentioned tank 26 is
The upper part of the thrower 9 connected to the terminal end of the number conveyor gutter 4 is connected to the upper part of the thrower 9, and the lower outlet of the tank 26 is made to look inward at one end of the rotary sorting cylinder 11, and downward at the other end of the rotary sorting cylinder 11. The lower part of the gutter 25 hanging vertically connects to the communication port 2 formed in the upper side of the No. 2 conveyor gutter 7.
A receiving gutter 12 with a spiral conveyor 28 mounted thereon is installed inside the rotary sorting cylinder 11 so as to communicate with the rotary sorting cylinder 11 . The gate valve 29 is extended so as to approach the
At the terminal end of the receiving trough 12, a lifting tube 30 for taking out the grains is connected and connected.

Therefore, during work, grains, etc. that are threshed in the handling room 2 and leak through the crimp net 17 are sorted through the sorting style 3.
It is selected by the wind and falls into the No. 1 conveyor gutter 4, and is transferred to the handling room 2.
The dust discharged from the terminal end is sorted by the sorting plate 20, and the waste is discharged from the third port 22 while being sucked by the axial flow fan 21, and is transported from the sorting fan 3 or falls from the sorting plate 20. The second item falls into the second conveyor gutter 7, is conveyed by the spiral conveyor 8, and is directly returned to the handling chamber 2 by the second thrower 6 to be reprocessed.

In addition, the grains, etc. that have fallen into the No. 1 conveyor gutter 4 are conveyed by the spiral conveyor 5, jumped up by the thrower 9, and supplied from the tank 26 to the rotary sorting cylinder 11, which rotates as shown by arrow A. When the unit engages with each pot hole 10 of the sorting barrel 11, it is lifted up as it is, and when it passes the gate valve 29, the single grain falls into the receiving shaft 12 as shown by the arrow B, and is placed in the pot hole 1.
If the twigs, culms, etc. that do not engage with the gate valve 29 and are separated by the gate valve 29 reach the terminal end, they will fall into the gutter 25 and the communication port 27
The fine grains fall into the No. 2 conveyor gutter 7 and are returned to the handling room 2, and the fine grains that fall into the receiving gutter 12 are conveyed by the spiral conveyor 28 and taken out from the lifting cylinder 30. It turns out.

In this way, the present invention has a No. 1 conveyor gutter installed below the sorting chamber below the handling chamber containing the handling cylinder, and a No. 2 thrower connected to the handling chamber behind the No. 1 conveyor gutter. A No. 2 conveyor gutter is installed that communicates with the processing chamber, and a pot hole type rotary sorting cylinder is installed on the upper side of the processing room, which communicates with the No. 1 conveyor gutter via a thrower, etc. The equipment is installed so that the first grain is taken out from the receiving gutter installed in the conveyor gutter, and the terminal side of the rotary sorting cylinder and the upper side of the second conveyor gutter are connected, so it is installed in place of the conventional oscillating sorter. The pot-and-hole type rotary sorting cylinder enables the first grain to be selected with good sorting performance, and the rotary sorting cylinder is installed well on the upper side with little vibration to improve the flow of the material to be sorted. It has the advantage that it can be well constructed so that the overall height of the aircraft does not increase, and that it can be suitably implemented.
