Description

[Detailed Description of the Invention] Industrial Application Field Problems to be Solved by the Invention The present invention has a sorting plate at the end thereof which is provided with a leakage hole for leaking and sorting the grains while swinging as they undergo threshing. In the case of a swinging sorting shelf, due to the falling state of the straw pieces from the end of the sorting plate, a large amount of straw pieces may leak into the grains to be sorted, or the second straw may be picked up. Straw waste often falls into clumps into the second processing equipment.

Means for Solving the Problem This invention provides a sorting plate (2) at the terminal end of which is provided with a leakage hole (1) through which the grain leaks out while swinging in response to threshing.
A rack (3) for sending out straw waste is formed on the upper edge, and a rack fin (4) protrudes from the end of this sorting plate (2) in the sending direction.
) are arranged at appropriate intervals in the lateral direction, and between each of the rack fins (4) there is a rack protruding below the upper edge of the rack (3) and longer than the rack fin (4) to receive straw waste. A swinging sorting shelf of a threshing device is configured with swinging sieve wires (5) arranged therein.

Functions and Effects of the Invention The threshed grains threshed in the barrel chamber are received by the swinging sorting shelf, and the grains are sorted by the sorting plate (2) of the swinging sorting shelf and the rack (3) of the rack fin (4). The grains are separated and sorted into grains with branches and stalks attached, straw waste, etc., and the grains are allowed to leak through the leakage hole (1) of this sorting plate (2) and discharged outside the machine by a grain frying device, and grains with branches and stalks are separated. are dropped into the second processing device through the gap between the rack fins (4) and the stripes (5) of the sorting plate (2), and are returned to the processing barrel by the second processing device. The straw is threshed again in the barrel chamber, and the straw waste is deposited on the rack fins (4) that protrude from the end of the sorting plate (2) in the delivery direction and on the line (5) provided on the top of the sorting plate (2). The rack fins (4) are quickly transported while being picked up and sucked out by a dust suction device.
Since the interval at which the straw waste falls is narrowed between the line (5) and the line (5), the amount of straw waste falling into the second processing device is greatly reduced.

Embodiment In the illustrated example, the combine harvester (6) is provided with a traveling device (7) having a crawler at the bottom, and this traveling device (7)
Above are the threshing device (8), the prime mover (9) and the driver's seat (10).
), etc., and a reaping device (11) for reaping and transporting the husk culm is installed in the front part of the threshing device (8), and the reaping husk is transferred between the chez 7 (13) of the threshing device (8) and the clamping plate. The threshing process is carried out while being held and transferred by the culm (14), and the threshed culm is cut by the culm processing device (12) at the rear and discharged onto the field surface.

The threshing section rill (8) receives the husk harvested and transferred by the reaping device al (11), and transfers it rearward while being held between the chê 7 (13) and the holding plate (14). While doing so, the pump (1) stuck to the handle ff1 (18) in the handle barrel chamber (15)
The threshed grains threshed by step 7) are divided into two types: one that leaks from the handling chamber network (18) at the bottom of the handling barrel chamber (15), and one that leaks from the handling chamber net (18) at the bottom of the handling barrel chamber (15).
) The grains are separated from those discharged from the rear opening (19), and the threshed grains leaked from the handling room network (18) are

20), and this swing sorting shelf (2
0) is provided with a sorting plate (2) between both side plates (21), and this sorting plate (2) has a mountain-shaped base and a flat tip.
This planar part has a leakage hole 1) through which grains leak, and a rack fin (4) with a rack (3) protruding from the terminal end of the sorting plate (2) in the feeding direction is provided. The racks (
3) It has a structure in which stripes (5) protruding longer than the rack fins (4) below the upper edge are fixed at appropriate intervals, and a helix (22) is attached at the bottom of the swinging sorting shelf (20). A built-in helical shelf (23) is provided, and the grains leaking from the leakage hole (1) are transferred by this helical (22) and discharged to the outside of the machine by a grain lifting device 1l (24). Yes, the line (
5) There is a second processing bag at the bottom! l (25), this second processing device (25) consists of a second door gutter (27) and a jumping device (2nd), which has a built-in second spiral (26).
The grains with branch stalks and part of the straw waste separated and sorted by the swing sorting shelf (20) are transferred to the second processing device (25) in the handling barrel chamber (1).
5) A dust suction device (29) is provided at the rear of the handling barrel chamber (15), and the opening (
19) The straw waste discharged from the section and the rack fin (4)
The dust suction device FL (29) sucks up the straw waste transported on the line (5) and removes it from the machine by the combine harvester (6). The crawler of the traveling device (7) is rotationally driven by the rotation of the prime mover (9) to travel, and the grains harvested by the reaping device (11) are transferred to the rear threshing section ( 8), the grain is transferred to the rear by being clamped between the ché 7 (13) and the clamping plate (eye), and then threshed in the handling barrel chamber (15). 18) The grains leaking from the handling chamber (15) and the grains discharged from the opening (19) of the handling chamber (15) are separated, and the threshed grains leaking from the handling chamber network (!8) are collected on the swing sorting rack. (20) supplied above.

While being transported backward on this oscillating sorter n (20), it is separated and sorted into grains, grains attached to branches and straw waste, and the grains are passed through the leakage hole (1) of the sorting plate (2) to the helical shelf ( 23) It leaks onto the top, and is not re-sorted by the suction air of the dust suction device (29) on this helical shelf (23), but is transferred by the helical (22) and sent to the frying device! (24) and is discharged out of the machine, and the ramus grains are transferred to the rear on the rack fins (4) and streak lines (5) while being transferred to the rear. falls into the No. 2 disposal device (25) through the gap, and the No. 2 spiral (
2B) It is transferred to the handling trunk room (1) using the jumping device (28).
5) The straw waste that is returned to the interior of the interior, is re-thrested in this handling barrel chamber (15), and is discharged from the opening (fill) of the handling barrel chamber (15), the rack fin (4), and the straw waste. The straw that rides on the node line (5) and is transferred to the rear is the dust suction device (29).
It is sucked in and discharged outside the machine. The straw waste rides on the rack fins (4) and the chain part M (5) and is removed from the dust suction device (2).
8) The second processing device (25
) The amount of straw waste falling into the tank decreases.
