Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is provided with an oscillating sorter for receiving and swinging and sorting an object to be treated which leaks from a handling chamber, and an object to be treated by this oscillating sorter. The present invention relates to a threshing device which is provided with a Kara-miso which performs a wind-selecting action on the above, and which is provided with an air-exhausting device which sucks exhausted waste chips and the like selected by the wind-selecting air by the Kara-mitsu and discharges them outside the threshing room.

[Conventional technology]

Conventionally, in constructing the swing selecting device, for example, as shown in FIG. 4 of Japanese Patent Laid-Open No. 1-228412, a Glen pan and a rack plate, or a Glen pan and a chaff plate (not shown) are arranged in front and back in that order. It was arranged. Then, the handling objects from the handling room are received by these pans and rack plates,
The specific gravity difference was selected by the rocking action.

[Problems to be Solved by the Invention]

However, since the selection is performed by swinging the Glen pan, the rack plate and the like, there is a limit to the selection performance.
In other words, when mowing is performed in a state with a large amount of morning dew and the treated material contains a large amount of moisture, or when the treated material is large, the treated material accumulates in multiple layers on the rack plate, and the first material leaks Lower efficiency becomes worse. On the other hand, when the amount of treated material is small, it may leak too much, and the waste straw may be collected together with the first material. In any case, it is difficult to adapt to all conditions.

Therefore, it may be possible to adjust the leakage pattern according to the amount of the treated material, but even with such adjustment of the pattern, sufficient sorting performance could not be achieved yet.

An object of the present invention is to provide a rational mechanism in a leaking space between a handling chamber and a swing sorting device, and configure a swing sorting device in accordance with this mechanism to improve sorting performance of handled objects, and The object of the present invention is to provide a product that can improve the sorting performance even for a processed product that falls from the dust cleaning port in an unprocessed condition than the treated humidity.

[Means for solving the problem]

A characteristic configuration according to the present invention is to provide a lateral feed conveying screw for laterally feeding the treated material leaking from the handling chamber between the left and right threshing side plates, and a guide for guiding the treated object toward the lateral feed conveying screw. A mechanism is provided, and a leaking mechanism that leaks a selected product out of the processed products fed by the lateral feed conveying screw is provided, and the leakage does not occur at the conveying end position of the lateral feed conveying screw by the leakage mechanism. A discharging device for discharging the roughly selected processed product is provided, and the finely selected processed product sent out by the discharging device is shaken by a precise sorting section that receives the carefully selected processed product from the leakage mechanism and performs swing selection. A coarse sorting unit for performing dynamic sorting is provided in the swing sorting device, below the dust sweep port formed at the end of the handling chamber, above the swing sorting device, and above the transverse feed screw from the Karako Kazekata On the lower side, there is a blower capable of sucking the sorted wind and blowing air to the untreated matter falling from the dust sweeping port in a length that extends between the left and right threshing side plates, and its action The effects are as follows.

[Work]

In other words, the processed product that leaks from the handling room is laterally fed by the lateral-feeding transport screw, and the selected product that contains a lot of grains is dropped into the selected part through the leakage mechanism, and the processed product is Swing sorting is performed in the fine sorting section. On the other hand, the roughly selected product that has been conveyed to the terminal end of the horizontal conveying screw and has not leaked is discharged by the discharging device and dropped and supplied to the coarse selecting unit,
The rough selection section swings and sorts the roughly selected products.

The side-feeding transport screw and the leakage mechanism can separate the treated material into a finely-selected treatment material and a rough-selection treated material and supply it to the rocking / sorting device. Since it is possible to add a "fir" effect to the processed material, it is also possible to impart a singulation function to the lateral feed conveying screw.

Since it can be laterally fed by the lateral feeding / conveying screw, it is possible to uniformly leak the finely processed product leaked by the leakage mechanism in the lateral direction of the fine sorting unit.

Since the roughly selected product is thrown out by the sending device, compared with the case where it is simply dropped, the throwing driving force of the throwing device can be directly added to the roughly selected product as a "tapping" action. It is possible to improve the separation by knocking out the “clam fir” that has entered into the second material such as the rice with branches. In addition, by throwing out the roughly selected product, the entanglement between the second products can be released in the throwing state.

By blowing air from the air blower, the untreated material falling from the dust port can be blown away, and the combined state of the exhausted straw, second material, and first material as the untreated material can be decomposed and dispersed, and the untreated material can be swung. Easy to select just by selecting. Moreover, since this air blower is located on the downwind side of the traverse feed screw and the blower, it can suck the selection air,
A suction force is applied to the loosely-treated product to be released, and as a result, the release force of the delivery device is increased to exert the effects of "decomposition loosening action" and "tapping action" on the coarsely-treated product. In addition to being able to further improve, it also drops into the fine sorting section in order to aspirate the lightweight dust contained in the carefully sorted material leaking from the leak mechanism and remove it before it drops into the fine sorting section. The selection processing of the remaining processed products can be performed more easily.

〔The invention's effect〕

(A) Due to the operation, even if the amount of processed material is large or small, rough sorting is added in advance in the preceding step of the rocking sorting device, so that the products sorted by the rocking sorting device can be separated and dispersed. Further, by forming the meshes of the fine sorting section and the rough sorting section exclusively for it, the sorting performance can be further improved.

(B) Moreover, since the objects to be treated are dispersed in the rocking / sorting device further than the action, the sorting performance can be further improved.

From the above (a) and (b), it is possible to greatly improve the sorting process performance as compared with the conventional structure, regardless of the amount of treated amount and the amount of moisture of the treated substance.

(C) However, there is a method disclosed in, for example, Japanese Utility Model Laid-Open No. 62-74540, which has the same effects as those shown in (a) and (b). At the terminal end of the screw, since the roughly-selected product conveyed by the screw is simply dropped, there is no "tapping" action as shown in the action of the present invention, and therefore, the "scissor fir" phenomenon occurs. The effect of eliminating it is small. Moreover, in the case of the present invention, there is also an advantage that a wind-selecting action by the blow-off device by the blow-off device can be expected, and the selecting action can be added before the dropping to the rough sorting section.

(D) If the Karato wind is too strong, the first thing on the rocking sorter will be discharged to the outside of the machine, so the Karato wind cannot be strengthened, but the suction force of the air exhaust device will also reduce the weight of dust. Since there is only a suction force for discharging, the air selection effect on the unprocessed material falling from the dust port is not sufficient.By installing the air blower, the first material is discharged to the outside of the machine. The unprocessed material can be well sorted without doing so. However, if only this effect is grasped, it is similar to the invention disclosed in, for example, Japanese Patent Laid-Open No. 61-74517. However, in the case of the present invention, the blower is arranged in the direction of Karafu wind of the transverse feed screw. By arranging it on the side and erected between the threshing side plates as much as possible, it is possible to achieve the action described in action (d), increasing the throwing force for the coarsely processed product and separating it from the carefully selected product. The effect of promoting the sorting action can be achieved.

As described above, by providing a single blower device with suction action below the dust sweep port, it is possible to increase the overall sorting capacity and contribute to the improvement of the most product recovery efficiency. I was able to do it.

〔Example〕

The threshing device mounted on the combine will be described.

The horizontal feed screw (9) is set to feed from the tip side of the threshed grain culm to the root side, and the treated material is conveyed to the root side, and then selected through the crimp net (12). Let things leak. Therefore,
The treated materials gathered on the tip side depending on the rotating direction of the handling cylinder (1) were fed to the stocker side by the transverse feed transport screw (9) and allowed to leak through the crimp net (12) to make them substantially uniform. In this state, the selected products can be leaked to the rocking and sorting device (3). For the seaweed, the side-feeding conveying screw (9) and crimp net (12) "fir action" on the processed material.
