Description

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

In other words, it is structured so that grains can be sorted inside the handling barrel without incorporating a conventional swinging sorting device, and there is no vibration or noise caused by swinging, which is compared to the conventional method. To provide a threshing machine which can be constructed in a compact size, can be easily mounted and incorporated into a combine harvester, and can particularly perform first sorting well.

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

The handling barrel A, on which the handling teeth 1 are implanted on the outer circumferential surface, is formed so as to open both end faces of one starting end side (a) and the other end side (b), and the grains are engaged with the inner peripheral surface of the handling barrel A. A boss 8 supported by each arm 17 is installed at the inner center of the handling cylinder A, which is closer to the starting end side A, and a handling cylinder axis 9 is formed.
is inserted into the boss 8 and the handling cylinder A is mounted in the handling chamber 10. However, the handling cylinder shaft 9 is slightly tilted to tilt the handling cylinder A, and the crimp net 4 is installed on the lower side of the handling chamber 10. A supply port 11 and a straw discharge port 12 are installed at both lower ends of the handling chamber 10, and a feed chain 13 and a straw culm 14 are extended along the outside of the handling chamber 10.

At the inner upper part of the handling cylinder A, a receiving gutter 3 which is open at the top is installed in an inclined manner along the longitudinal direction of the handling cylinder axis 9. It extends outward through the side hole, and the sloping lower side end of the receiving trough 3 is connected to the lower part of the grain lifting cylinder 16 in which the spiral conveyor 15 is mounted inside, and the upper end of the grain lifting cylinder 16 is connected to the outlet side. It is constructed by extending the pipe to communicate with the paddy tank, etc.

A helical conveyor 5 is installed in a conveyor gutter 18 installed horizontally below the crimp net 4, and the terminal end of the helical conveyor 5 is connected to the lower part of a grain lifting cylinder 6 in which a helical conveyor 7 is installed inside. Fried grain cylinder 6
The tip of the discharge gutter 20 extending below the tank 19 communicating with the upper end side is installed so as to look into the upper part of the starting end side of the handling barrel A.

In addition, a wind screening section B is installed at the rear of the handling chamber 10, and a second gutter 22 is installed below the sieve line 21 extending from the lower side of the terminal end of the handling barrel A. A No. 2 conveyor 23 is mounted on the No. 2 gutter 22, and the sorting air from the pressure winch 24 flows above the No. 2 gutter 22 and flows out to the rear No. 3 port 25 side. A No. 4 gutter 26 communicating with the straw discharge port 12 is installed above the wind sorting B.

During work, the grain rods fed from the supply port 11 while being conveyed by the feed chain 13 are threshed by the handling teeth 1 of the handling cylinder A while the handling cylinder A rotates as shown by arrow D, and the straw is removed. Straw outlet 1
It will be discharged from 2.

The grains leaking through the crimp net 4 fall into the conveyor gutter 18 and are carried out by the spiral conveyor 5 and handed over to the grain lifting tube 6, where they are lifted up by the spiral conveyor 7 inside the grain lifting tube 6. It is sent into the tank 19, and the handling cylinder A is sent from the lower discharge gutter 20.
The handling cylinder A rotates in the direction of arrow 2 when it is thrown into the container.
While the paddy is engaged with the pot hole 2 on the inner periphery and is lifted upward by rotation, the paddy is received into the receiving trough 3 as shown by the arrow H, and in this way, it is sequentially received into the receiving trough 3. The rice grains flow down the receiving trough 3 and flow into the lifting tube 16, and are lifted up by the spiral conveyor 15 inside the lifting tube 16 to take out the grains.

In addition, the grains with branches remaining in the handling cylinder A are discharged from the terminal side of the handling cylinder A, and are sent onto the sieve wire 21 along with the dust discharged from the terminal side of the handling chamber 10. There, the second material is air-selected by the pressure air from the pressure air handle 24, falls into the second gutter 22, is carried out by the second conveyor 23, and is returned to the handling room 10 as in the conventional type, where the waste material is collected. is Exit 3 25
This will cause more waste to be ejected from the aircraft.

In this way, the present invention has a number of pot holes formed on the inner peripheral surface of the handling barrel with handling teeth implanted on the outer circumferential surface, and a hole extending outward from the terminal end of the handling barrel at the upper part of the interior of the handling barrel. A receiving gutter is constructed so that grains, etc. can be supplied from the spiral conveyor installed below the crimp net below the handling drum to the inside of the starting end of the handling drum via the grain lifting cylinder, and then opened. Since the terminal end of the handling barrel is connected to the wind sorting section, grains can be sorted inside the handling barrel without using a swinging sorting device as in the conventional type. , unlike conventional machines, there is no vibration or noise caused by rocking, and since there is no rocking sorting device, the machine body can be made relatively compact and can be easily mounted and incorporated into a combine harvester.
It has the advantage of being able to perform number selection with high precision.
