Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sorting and waste treatment device for a threshing machine.

[Conventional technology]

Conventionally, in a threshing machine configured with a swinging sorter extending from the bottom of the handling chamber to the dust removal side, the untreated dust discharged from a part of the swinging sorter was collected in a direction perpendicular to the handling barrel. There is no structure that allows processing while taking it in by a processing cylinder, and also allows part of it to be scattered to the front of the processing chamber when the amount of processing becomes large while being processed by this processing cylinder. .

[Problem that the invention attempts to solve]

This invention enables the untreated dust discharged from a part of the oscillating sorting body to be properly taken in by the processing cylinder in the direction perpendicular to the handling cylinder, while also being able to process it well without causing No. 3 loss. When the amount of processing by the cylinder increases, it can be automatically scattered to the front suction sorting dust removal chamber, reducing horsepower loss during high loads, and improving suction dust removal by scattering. Further, it is possible to re-sort the dust on the swinging sorter, and there is no clogging of the concave, so that the dust can be reliably and well sorted and discharged.

[Means for solving problems]

Therefore, in the present invention, a processing chamber is formed above a concave installed above the terminal end of the oscillating sorting body, in which a processing cylinder is mounted perpendicularly to the processing cylinder, and a oscillating A suction sorting dust removal chamber is formed in a continuous manner above a part of the sorting body, and an upper inner side of the suction sorting dust removal chamber is formed at the upper end of the front surface of the processing chamber facing the suction sorting dust removal chamber. It is constructed by installing a guide plate that can be rotated toward the processing chamber and biased toward the processing chamber.

[Effect]

With this configuration, it is possible to smoothly and efficiently take in the untreated dust that is sent out from a part of the oscillating sorter and process it without causing No. 3 loss, increasing the amount of waste that can be processed by the processing cylinder. In such cases, the dust is automatically scattered to the front suction sorting dust removal chamber to reduce horsepower loss during high loads. This means that dust can be sorted out properly without clogging the concave.

〔Example〕

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

Figure 2 shows a sectional view of a threshing machine mounted on a combine harvester.A supply port 8 and a straw discharge port 9 are formed on both sides of the lower part of a handling chamber 1 in which a handling barrel 3 is installed. A crimp net 10 is stretched, and a downward dust inlet 11 is formed at the terminal end thereof, and a No. 4 gutter 12 is installed above the outer side of the straw discharge opening 9, so that the machine can be accessed from below the handling room 1. The swinging sorting body A extending toward the rear dust exhaust port 13 has a chaf sheave 14 and a grain sheave 15 located above and below the middle, and a chaf sheave 14 and a grain sheave 15.
A stroke rack 16 is disposed from the rear of the stroke rack 16, a chaff sheave 17 is disposed from the lower end of the stroke rack 16 to the rear rear end, and a grain flow plate 18 is disposed below the chaff sheave 17. A pressure fan 19 is mounted on a shaft below the starting end side of the grain sheave 15, and a grain board 20 is installed diagonally below the grain sheave 15.
A No. 1 spiral conveyor 21 is installed horizontally below the straw racks 16 and grain distribution plates 18, and a No. 2 spiral conveyor 22 is installed horizontally below the straw racks 16 and the cereal grain board 18.

On the upper side of the stroke rack 16 and below the No. 4 gutter 12, there is formed a suction sorting dust removal chamber 6 with a suction dust ejector 23 connected to one side of the upper part, which forms the terminal side of the swinging sorter A. Above the chaff sheave 17 is a suction sorting dust removal chamber 6 whose front surface is above the end of the stroke rack 16.
A processing chamber 5 communicating with the rear part is formed, and within the processing chamber 5, a processing cylinder 4 having processing teeth 4a implanted on its outer peripheral surface is mounted on a shaft in a direction perpendicular to the processing cylinder 3, and a stroke rack 16 is attached to the terminal end of the processing cylinder 4. A concave 2 is installed in the lower part of the processing chamber 5, which is the rear side of the concave 2, a group of cutting blades 24 is arranged at the rear, and a dust outlet 13a is formed at the rear of one end of the processing chamber 5. At the bottom, a screen 25 made of a perforated iron plate that is inclined to be low in the front and high in the rear is installed obliquely so that its front end is located above the front end of the chaff sheave 17.

The upper part of the guide plate 7 that hangs down between the upper surface of the processing chamber 5 and the upper surface of the suction sorting dust removal chamber 6 at the upper end of the front surface of the processing chamber 5 facing the terminal end of the stroke rack 16 is attached to the support shaft 26. Pivotably installed, its support shaft 26
The guide plate 7 is
is installed so as to press against the processing cylinder 4 side, and when it collides with the stoppers 28, 28, it comes closest to the processing cylinder 4 side and the guide plate 7 is rotated to the upper inward side of the suction sorting dust removal chamber 6. be installed and configured so that it can be moved.

During work, the objects to be sorted that fall from the handling chamber 1 are shaken and sorted by the chaff sheave 14.
The first grains leaking through the chaff sieve 14 and the grain sieve 15 are wind-selected and transferred to the first spiral conveyor 21.
The dust from above, from the chaff sheave 14 to the stroke rack 16, is sucked into the dust ejector 23.
2 which leaks from the stroke rack 16.
The articles fall onto the No. 2 spiral conveyor 22, and the untreated articles sent out from the top of the stroke rack 16 are taken in by the processing teeth 4a of the processing cylinder 4, which rotates as shown by arrow A, and are transferred directly to the processing chamber 5. The dust is processed while circulating inside the concave 2, and the waste is discharged from the dust exhaust port 13a, while the second dust etc. leaking from the concave 2 flows down on the screen 25.
The debris that leaks from the screen 25 is shaken and sorted by the chaff sieve 17 located below, and the debris that falls from the lower end of the screen 25 to the starting end of the chaff sieve 17 is shaken and sorted by the chaff sieve 17. The second grains sent to the port 13 and leaking from the chaff sieve 17 fall from the flow board 18 onto the second spiral conveyor 22 and are processed.

In this case, when the object to be processed is circulated in the processing chamber 5 by the processing cylinder 4, it is guided by the guide plate 7 and is again circulated downward as shown by the arrow B to be processed. As the number of objects increases, the object to be processed presses the guide plate 7 forward, and the torque spring 27 expands, causing the guide plate 7 to rotate forward as shown by the imaginary line in FIG. As a result, the material to be processed is scattered into the suction sorting dust removal chamber 6 as shown by arrow C, and some of the light dust is transferred to the suction dust removal machine 2.
3 and those that fall onto the stroller rack 16 will be sorted out again.

In addition, when the amount becomes normal, it will be rotated forward until it hits the stopper 28 by the force of the torque spring 27, and will return.

[Effect of idea]

In this way, the present invention allows the untreated dust sent out from the swinging sorter A to be smoothly and efficiently taken in by the processing cylinder 4 in the direction perpendicular to the handling cylinder 3, so that no waste is caused. When the amount of waste to be processed by the processing cylinder 4 increases, the guide plate 7 is pressed and the dust is automatically rotated forward, scattering the dust into the suction sorting dust removal chamber 6 for good separation. This reduces horsepower loss during high loads, improves suction and exhaustion of dust, and allows for good re-sorting on the oscillating sorter A, preventing it from clogging the concave 2. It has the advantage of being able to sort and remove dust well, and has a simple structure that allows it to be suitably implemented.
