Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a particle removal sorting dust removal device for a DC type combine harvester.

In other words, in the DC type combine harvester, the grains can be removed well in the grain removal cylinder chamber, and the dust can be properly removed directly without passing through the sorting chamber, so that the sorting can be performed well.
The width of the sorting chamber is narrower than that of the threshing cylinder chamber, so that necessary and sufficient sorting can be carried out, and the machine body can be downsized, so that it can be carried out suitably.

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

FIG. 1 shows a side view of a DC type combine harvester, which is constructed by installing a threshing sorting section B on the upper part of the machine body supported by both crawlers 15 and a reaping section A at the front part. , Grass dividing board 16,1 on both sides of the frontmost side
A grain culm lifting device 2 is provided with a grain culm lifting device 6 protrudingly provided, and a known tine 1 is installed between both grass dividing plates 16, 16 so as to be freely retractable.
6 of them are arranged side by side with a slight inclination, and the cutting blade 3 is installed horizontally at the rear lower part close to the lower part of each device 2,
The upper part of an auger gutter 5 installed horizontally close to the rear of the cutting blade 3 is open, and a horizontal auger 4 is rotatably mounted inside the auger gutter 5 and extends upward from the rear of the auger gutter 5. Upper end 6 of guide plate 6
A is extended to the rear of the upper side of each grain culm pulling device 2, and one end side of the auger gutter 5 is connected to the lower part of a conveyance gutter 17 extending to the rear upper part, and the conveyance gutter 17
A belt-shaped conveyor 7 with projections capable of conveying grain culms is rotatably installed inside.

The sloughing and sorting section B has a sloughing cylinder chamber 8 installed horizontally in the upper front part, and rotates a sloughing cylinder 10 having a large number of handling teeth 27 in the sloughing cylinder chamber 8 with a net 26 stretched around the lower side. Freely mount the shaft,
A reception port 9 is connected to one end side of the threshing cylinder chamber 8.
The upper end side of the conveyor 7 is seen, and a sorting chamber 12 is constructed from the lower part toward the rear of the half of the sloughing cylinder chamber 8 that is closer to the receiving port 9. A swinging sorting body 11 extending rearward from the bottom of the chamber 8 is installed, and a pressure fan 18, a No. 1 spiral conveyor 19, and a No. 2 spiral conveyor 20 are arranged below the swinging sorting body 11, respectively. At the rear end of the sorting chamber 12 there is a downward dust exhaust section 2.
1 and configure it.

Further, a dust exhaust port 22 is provided on the other end side of the shedding cylinder chamber 8, which is on the outside of the sorting chamber 2 and opposite to the receiving port 9 side.
2 and the lower part of the mesh body 26 of the threshing cylinder chamber 8 is partitioned by a partition plate 28, and the spiral conveyor 13 is extended from the partition plate 28 to above the oscillating sorting body 11 in the sorting chamber 12. Further, a dust exhaust path 14 communicating with the dust exhaust port 22 is provided to extend rearward along the outer lower part of the sorting chamber 12, and a terminal side exhaust port 23 of the dust exhaust path 14 is directed downward in front of the engine section 24. It is configured with an opening.

Further, 25 is a dust removal blade provided at a portion corresponding to the dust removal port at the end of the handling chamber.

Therefore, during work, even the grain culms that have fallen down are raised by each grain culm lifting device 2 and harvested by the cutting blade 3, and at the same time, the grain culms in the raised state are left leaning against the guide plate 6 and raised by the auger 4. It is conveyed as shown by the arrow A, and then conveyed upward as shown by the arrow B by the conveyor 7 to the receiving port 9.
The grains are then charged into the threshing cylinder chamber 8.

Therefore, the grains etc. threshed by the threshing cylinder 10 fall into the swinging sorter 11 located below and are sorted in the sorting chamber 12 while the waste is discharged from the dust exhaust port 21 and the dust is discharged from the threshing cylinder chamber 8. The dust is transferred in the direction of arrow C and discharged from the dust exhaust port 22 into the dust exhaust path 14, and flows as shown by arrow D and is discharged outside the machine from the discharge port 23. The grains falling downward from the end side are transferred to the oscillating sorter 11 by a spiral conveyor 13 as shown by the arrow H.
They will be transported to the side and sorted.

In this way, the present invention has a threshing cylinder chamber installed horizontally in the upper part, which receives the grain harvested by the harvesting section at the front of the machine body from the receiving port on one end side, and a threshing cylinder chamber in the lower part near the receiving port side of the grain threshing cylinder chamber. A sorting room containing a swinging sorter, etc. was installed, and a dust exhaust path was extended from the other end of the threshing cylinder chamber toward the rear of the machine. In addition, the dust discharged from the other end of the particle removal cylinder chamber can be effectively removed directly without passing through the sorting chamber, and the sorting is carried out inside the sorting chamber. The sorting chamber can be made narrower than the threshing cylinder chamber to perform the necessary and sufficient sorting, and its narrow structure allows the machine to be made smaller, making it suitable for implementation. It has characteristics.
