Description

[Detailed description of the invention] Industrial applications The present invention relates to a sorting dust removal device for a threshing machine.

Conventional technology Conventionally, at the rear of a sorting room equipped with a swinging sorting shelf that receives threshed grain in a threshing room and sorts it while moving it, there is a wall in the sorting room above the swinging sorting shelf. A suction dust removal chamber is provided for sucking and discharging sorted waste, and a straw discharger is provided at the rear end of this swinging sorting shelf to discharge straw waste transferred from the upper surface of the swinging sorting shelf to the outside of the suction and dust removal chamber. A straw outlet was provided, and this straw outlet was a sorting dust removal device that opened to the outside of the Direct IIi machine.

Problems to be Solved by the Invention The husks supplied into the threshing chamber are threshed while being transported through the threshing chamber, and the threshed grains and straw waste generated during the threshing process are separated from each other in the sorting chamber. The grains are fed to a swinging sorting shelf, where they are shaken and separated into grains and straw waste, and while the grains are leaking from the swinging sorting shelf, they are air-sorted in the sorting room. The air-sorted grains are discharged outside the machine, and the straw waste is oscillated on the upper surface of the oscillating sorting shelf and supplied into the suction and dust removal chamber. and the straw discharge port on the rear side of the suction and dust removal chamber to the outside of the machine.
In the machine, when a stronger wind is blowing in the direction opposite to the straw waste discharge direction during this threshing operation, this strong wind blows into the machine through the straw outlet, and the straw waste is This creates resistance to the straw waste being discharged, and a large amount of straw waste leaks from the swinging sorting shelf into the sorting chamber, resulting in a decrease in grain sorting performance.

Means for Solving the Problems This invention provides a rear part of a sorting room (3) equipped with a swinging sorting shelf (2) for receiving threshed grains shelled in a threshing room (1) and sorting them while moving them while swinging. A suction dust removal chamber (4) is provided above the swinging sorting shelf (2) for sucking and discharging the sorted dust in the sorting room (3). A straw discharge port (5) is provided on the rear end side for discharging straw waste transferred from the upper surface of the swinging sorting shelf (2) to the outside of the suction and dust removal chamber (4).

A straw discharge guide plate (8) is inclined from the upper side of the straw discharge port (5) to the rear lower part, and the rear edge (6) is located lower than the lower edge (7) of the straw discharge port (5). ) is the configuration of a sorting dust removal device for a dehulling machine.

Effect of the invention The husk fed into the threshing room (1) is
The threshed grains and straw waste generated during the threshing process are supplied to the swinging sorting shelf (2) in the sorting room (3). (2), the grains are separated into grains and straw waste after being shaken and transferred, and while the grains are leaking from the shaking sorting shelf (2), they are wind-selected in the sorting room (3). The air-sorted grains are fried using a frying husk device or the like and discharged outside the machine, and the straw waste is oscillatedly transferred on the upper surface of the oscillating sorting shelf (2) and supplied into the suction and dust removal chamber (4). , this suction dust removal chamber (4
) is discharged outside the machine from the suction device installed on the negative side of the suction dust chamber (4) and the straw exhaust port (5) on the rear side of the suction dust chamber (4).
The straw waste discharged from the straw discharge port (5) is guided by a straw discharge guide plate (8) provided in an inclined manner from above the straw discharge port (5), and is discharged to the outside of the machine.

Effects of the Invention According to the present invention, the straw waste that is oscillatedly transferred on the upper surface of the oscillating sorting shelf (2) and supplied into the suction and dust removal chamber (4) is collected through the straw exhaust port of this suction and dust removal chamber (4). Straw is discharged outside the machine from (5), and a straw discharge guide plate (8) is provided which slopes from the upper side of this straw discharge port (5) toward the rear lower part, and the rear edge of this straw discharge guide plate (8) is provided. By locating (6) below the lower end of the straw discharging port (5) &i (7), even during threshing work when a stronger wind is blowing in the direction opposite to the straw waste discharge direction, This strongly blowing wind is blocked by the straw discharge guide plate (8), and the wind no longer blows into the machine from the straw discharge port (5), so that the straw waste to be discharged is subjected to wind resistance. This eliminates this problem and allows stable straw waste to be discharged at all times, so grain sorting performance does not deteriorate.
