Description

[Detailed description of the invention] The present invention consists of a first swinging sorting plate that sorts the threshing material that is dropped from the receiving net while being transferred to the rear of the machine, and a threshing machine that is dropped and fed from the dust exhaust port of the handling room. a second swinging sorting plate that sorts objects while transferring them to the rear of the machine; and a third swinging sorting plate that sorts objects that are dropped and supplied from the first and second swinging sorting plates while transferring them to the back of the machine. The present invention relates to a sorting unit structure of a threshing sorting device, which is provided and configured to be supplied with sorting air along the transfer direction by the first to third swinging sorting plates.

Conventionally, in the above threshing and sorting equipment, when trying to improve the sorting performance by increasing the sorting wind power, the amount of grains discharged outside the machine along with the sorting wind increased, and as a result, the sorting wind power could not be strengthened and the grains were sorted out. The disadvantages were that performance deteriorated and more grains were scattered outside the machine, resulting in greater grain loss.

The purpose of this invention is to create a device that has high sorting performance and reduces grain loss by making simple modifications that reduce the amount of grain discharged outside the machine even when the sorting wind power is increased. The goal is to make it available at a low price.

The characteristic configuration of the present invention is that in the sorting section structure of the threshing sorting device described above, the first and second swinging plates are arranged above the terminal end of the third swinging sorting plate and near the dust outlet to the outside of the machine. A member is provided for colliding and stalling the scattered waste from the dynamic sorting plate and guiding it down to the starting end side of the third oscillating sorting plate.

In other words, even if the sorting wind force is increased and the amount of processed material scattered toward the dust exhaust port increases, the scattered processed material is returned to the third swinging sorting plate by the guide member and separated into grains and dust. After sorting, the grains are supplied to the second grain take-out device, and the dust is again scattered with the sorting wind and discharged outside the machine, so the sorting wind power is increased to ensure good wind sorting. At the same time, the dust returned from the guide member together with the grains is transferred to the third
By sorting using the swinging sorting plate, it is possible to perform the sorting very well and to suppress the amount of grain discharged outside the machine along with the sorting wind. Moreover, it was a simple modification that required only the addition of a guide member, making it economically advantageous.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a handling barrel 2 is rotatably housed in a handling chamber 1 formed in the upper part of the body of the machine.
A threshing feed chain 3 that supplies harvested grain culm to the handling room 1 and transports threshed waste straw to the outside of the handling room 1,
It is provided outside the machine so that it can be driven and rotated freely, and constitutes a threshing section.
There is a swinging sorting plate 4 that sorts the threshed material supplied from the handling room 1 while transferring it to the rear of the machine, a winnow 5 that supplies sorting air along the direction of transfer by this sorting plate 4, and a dust winch that sucks dust out of the machine. A sorting section equipped with a fan 6 for discharging and a dust exhaust port 7 for discharging the sorting air to the rear of the machine together with dust is provided from the bottom to the rear of the handling chamber 1, and furthermore, the first processing material from the sorting section is A first screw conveyor 8 to be carried out of the machine;
The second part returns the second processed material from the sorting section to the handling room 1.
Each of the screw conveyors 9 is provided at the lower part of the sorting section, thereby forming a threshing and sorting device for a combine harvester.

The oscillating sorting plate 4 is composed of a first sorting plate section 4a that sorts the threshed material falling and supplied from the receiving net 10 of the handling chamber 1 while transferring it to the rear of the machine, and a handling chamber 1.
A second sorting plate section 4b that sorts the threshed material falling and supplied from the dust outlet 11 while transferring it to the rear of the machine.
are provided on the front end side, and the materials to be processed from the first and second sorting plates 4a and 4b are sorted while being transferred to the rear of the machine, and the second material to be processed is dropped and supplied to the second conveyor 9. The third sorting plate section 4c
are disposed below the terminal ends of the first and second oscillating sorting plate parts 4a and 4b, respectively, on the rear end side, and from the first and second oscillating sorting plate parts 4a and 4b, In addition, the plate member 12, which collides with and stalls the processed materials scattered by the sorting wind from the starting end side of the third oscillating sorting plate section 4c, and guides them downward toward the starting end side of the third oscillating sorting plate section 4c, is moved by the third oscillating motion. It is provided on the rear end side above the terminal end of the dynamic sorting plate section 4c and near the dust exhaust port 7.

The downstream guide member 12 may be of a fixed type as shown in FIG. 2, or a fan may be provided above the terminal end of the third swinging sorting plate portion 4c to mainly suck and discharge dust from the third swinging sorting plate portion 4c to the outside of the machine. 13, the case 13a of the fan 13 may also serve as a part of the downstream guide member 12.

the first to third swinging sorting plate parts 4a, 4b;
4c may be configured to be driven separately, and these may be connected to the first to third swinging sorting plates 4.
They are called a, 4b, and 4c.
