Description

[Detailed description of the invention] A threshing system in which a pressure winnowing machine is installed on one side of the lower part of the handling room to form a sorting style at the bottom of the handling room, and a swinging sorter for sorting the threshed grains is installed in this sorting air path. During threshing, the straw waste or pieces of straw get caught in the leakage sorting section made of the sorting net of the oscillating sorter, which prevents the grains from leaking out, and also removes the straw waste, etc. in which the grains are caught. The straw debris may slip on the top and flow into the second port, or the trapped straw debris obstructs the movement of other straw debris, which accumulates one after another, causing clogging and worsening the leakage of grains. In addition to this, there were also drawbacks such as poor ventilation of the sorting air and a marked decline in the ability to remove straw waste by air.

The purpose of the present invention is to improve the above-mentioned drawbacks.The present invention is designed to improve the above-mentioned drawbacks by installing a pressure-pressure winch on one side of the lower part of the handling chamber to form the lower part of the handling chamber into a sorting air passage. In a threshing machine equipped with a swinging sorter in the passageway, a wind control plate is provided in the sorting air passage so as to be able to swing up and down, and the windbreak plate is interlocked and connected to an intermittent drive mechanism to screen out leakage from the swinging sorter. This feature is characterized in that the clogging of straw waste in the filter is prevented by vibrating the sorting air.

The present invention will be explained in more detail with reference to the embodiment shown in the drawings below. Reference numeral 1 denotes a handling chamber with a handling cylinder 2 inside, a shaft rack, and a receiving net 3, and a pressure wind gutter located below the supply port 4 side. 5, the space extending from the lower part of the handling chamber 1 to the dust sorting room 6 is configured as a sorting air passage 7, and this sorting air passage 7 includes a transfer sorting plate 8a and a sorting plate extended to the end of the transfer. A leakage sorting body 8b made of a mesh, a first flow plate 8C, a chaff sieve 8d extending from its upper end toward the lower side in the transfer direction, and a rough sorting body 8e facing above are placed between the left and right side plates. It is constructed so that the attached swing sorting body 8 swings back and forth.

In addition, since a wind guide plate 11 is provided between the air guide plate 10 provided from the first receiving gutter 9 to the outlet of the pressure winch 5 and the transfer sorting plate 8a, the sorting air of the pressure winch 5 is Wind guide plate 1
0, it is divided into the sorting air that blows through the leakage sorter 8b and its tip side, and the sorting air that blows through the chaff sieve 8d from below the first receiving gutter 9 to above the second receiving gutter 12, and all the sorting air is The dust is blown out of the machine from the dust exhaust port 13.

A baffle plate 14 is swingably supported on the upper part of the discharge port of the air pressure kink 5 by a support shaft 15, and a projecting piece 16 attached to the end of the support shaft 15 is attached to an appropriate shaft 17. A spring 19, which is connected to a cam or other intermittent drive body 18 fixed to the cam or other intermittent drive body 18 and whose one end is locked to the side plate of the swinging sorting body 8,
is pulled in the return direction.

Therefore, the deflated grains leaking from the receiving net 3 are transferred to the transfer sorting plate 8.
After being subjected to specific gravity sorting by a, the straw waste is transferred toward the leakage sorting body 8b, and near its terminal end, the straw waste including the second straw discharged from the dust inlet 20 joins, and they are transferred to the leakage sorting body 8b.
While moving above, the grain leaks and falls into the first receiving trough 9, light straw waste is removed by the sorting wind that blows through the leakage sorter 8b, and cut ears of straw, etc., remain on the screen. The second material is further screened between the end of the leakage sorter 8b and the upper end of the first flow plate 8C, and then transferred to the chaff sieve 8d, where it is subjected to leakage screening and wind screening.

At this time, if straw debris enters the leakage hole in the leakage sorting body 8b, it will be bent by the sorting wind as shown in FIG. 3a and try to get caught.

However, the wind baffle plate 14 is intermittently vibrated by the rotation of the intermittent drive body 18, and the strength of the sorting air blown against the lower surface of the leakage sorting body 8b is varied. The debris stretches as shown in b and falls, and is blown up by the sorting wind from the gap between the leakage sorter 8b and the first flow plate 8C and discharged out of the machine.

Note that the baffle plate 14 may be driven manually or by engaging a clutch when the leakage sorter 8b is clogged.

The present invention provides a threshing machine in which a pressure winnowing machine is provided on one side of the lower part of the handling chamber, the lower part of the handling chamber is formed into a sorting air passage, and a swing sorting body is provided in the sorting air passage. A wind baffle plate is provided in the sorting air path so as to be able to swing vertically, and the baffle plate is interlocked and connected to an intermittent drive mechanism, so that when the baffle plate swings up and down, the screening air blown to the leakage sorter is intermittently. The strength of the straw fluctuates, and the straw stuck in the leakage hole of the leakage sorter bends and stretches each time, and when it stretches, the straw falls off and is discharged outside the machine by the sorting wind. This prevents straw waste from clogging the leakage sorter, preventing straw waste from building up on the leakage sorter and inhibiting the leakage of grains, and preventing grains from falling into the second opening along with straw and second grains. The sorting function is less likely to be degraded due to overloading, and stable and good sorting can be performed at all times.

Further, since the leakage sorting body is not clogged and straw debris does not accumulate, the straw debris can be accurately screened and removed by the sorting air blowing through the leakage hole.
