Description

[Detailed description of the invention] The present invention relates to a threshing device equipped with a fourth processing device for collecting the prickly grains that adhere to all the shell culms after threshing. A foot chain is installed on the side of a threshing machine frame with a sorting chamber at the rear so that its starting end is located at the front end of the machine frame and its terminal end is located at the rear end of the machine frame. In providing a shell culm conveyance passage for No. 4 processing from the straw outlet of the handling room to the rear end of the machine frame on the side part, an outer plate is provided below the foot chain to form the outer wall of the said conveyance passage. By extending it to the front end of the machine frame, the strength of the entire threshing device is improved, and this outer plate is also used as a safety cover for various power transmissions located below the foot chain on the side of the foot chain. This is to ensure safety.

Next, an example of the present invention will be explained with reference to a drawing. In the drawing, 1 is a machine frame of a threshing device, the front part of the machine frame 1 has a handling chamber 2 with a built-in handling cylinder 3, and the rear part has a handling chamber 2 in the lower part. Gutter 5 and second gutter 6
A sorting chamber 4 having a
A straw removal fan 8 is installed on the side of the handler, and as the threshed grains that have fallen from the handling chamber 2 onto the swing sorting mechanism 7 are sent backwards over the sorting mechanism 7, they are sent to the lower part of the handling chamber 2. The heavy grains are sorted by the air discharged from the installed structural type winnowing fan 9, and the heavier grains enter the first gutter 5, and are sent to the paddy receiving hopper 12 via the auger 10 and grain lifting tube 11, and then to the paddy bag 13. The second grains with twig stalks are sequentially stuffed into the second gutter 6 and are returned from the auger 14 to the handling chamber 2 via the second reducing thrower 15 and the passage 16, while the waste straw is The dust is sucked into the dust exhaust fan 8 along with the Chinese wind, and is then discharged to the outside of the machine via the duct 17.

Reference numeral 23 denotes a foot chain installed along the handling opening 22 of the handling room 2. By providing an outer plate 18 at the bottom of the culm, a foot chain is formed to form a husk conveyance passage 21 extending from the straw outlet 19 of the handling chamber 2 to the empty culm opening 20 at the rear end of the machine frame 1 on the side of the sorting chamber 4. 23, and the straw outlet 19 in the handling chamber 2 is formed vertically so that the shell culm after threshing goes out into the shell culm conveyance passage 21 in a suspended state. The bottom plate of the shell culm conveying passage 21 is connected to form a fourth gutter 24 that slopes downward toward the second gutter 6, while the rear part of the passage 21 is gradually expanded to a wider width toward the sorting chamber 4 side. A culm guide rod 26 is formed in the passage 25 and is inclined in the enlarged passage 25 so that its tip is located at the lower part of the passage 21 and its rear end is located inside the upper part of the enlarged passage 25. There is.

Then, the outer plate 18, which is located at the lower part of the foot chain 23 and forms the outer wall of the conveyance passage 21, is integrally extended to the front end of the machine frame 1, and the inner surface of the extension part of the outer plate 18,
In the space 33 formed by the lower part of the fourth gutter 24, the suction port 32 of the Karawin fan 9, the transmission belt 30 from the Karawin fan 9 to a part of the auger 10, the drive mechanism of the swing sorting mechanism 7, etc. It is equipped with various power transmission mechanisms.

In addition, 27 is a clamping rod along the foot chain 23, 28 is an input shaft to the handling cylinder 3, and a part of the second auger 14 is transmitted to the belt 31 from the other end of the auger 10.

In this configuration, the shell culm supplied to the starting end of the foot chain 23 is transferred to the handling chamber 2 while the stock part is being held between the foot chain 23 and the clamping rod 27. The husk enters the interior and is threshed, then exits from the handling chamber outlet 19 to the culm conveyance passage 21 connected thereto, and is conveyed in the passage 21 in a suspended state with the tip facing down.

During transportation in this suspended state, the stinging grains that adhere to the empty culms fall into the fourth gutter 24 and are collected, and then into the passage 21.
The tip portion comes into contact with the guide rod 26 provided in the enlarged portion 25 of
Thereafter, as it is fed along this guide rod 26, its attitude is gradually changed from a suspended state to a horizontal state, and after becoming in a horizontal state, it is sent out of the machine from the rear end of the foot chain 23.

In this way, in the present invention, the outer plate 18 for forming the outer wall of the conveyance passage for No. 4 processing provided along the foot chain is extended to the front end of the machine frame 1. The side surface on the foot chain side can be constituted by a single outer plate 18 from the front end to the rear end.

Therefore, according to the present invention, not only can the overall strength be significantly improved, but manufacturing is also simple and costs can be reduced.Moreover, this outer plate 18 can also be used as a safety cover at the lower side of the foot chain side. Then, inside it, install the intake port of Karachi fan or Karachi fan, Ichiban auger,
Since a power transmission mechanism to the swinging sorting mechanism can be provided, the outer plate of the second plate has the effect of ensuring safety for the foot chain side.
