Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a threshing and sorting device, and more particularly, to means for reprocessing the second processed material from the sorting section and returning it to the sorting section.

[Conventional technology]

Conventionally, in threshing sorting equipment, there is a horizontal screw conveyor that conveys the second processed material from the sorting section to one side of the machine, and a horizontal screw conveyor that is located at the starting end of the handling chamber or upstream of this with respect to the sorting section. By connecting the upper side of the reprocessing chamber in the transport direction of the processed material with a thrower-type lifting device, the second processed material from the sorting section is reprocessed and sorted in the sorting section. In order to ensure that this is carried out as reliably as possible, the structure is such that the waste is returned to a point located on the upper side of the sorting section in the direction of transfer of the processed material as much as possible. Care has been taken to obtain an inexpensive arrangement for transporting the I'1 product to the supply destination, which will be located at the level.

[Problem that the invention seeks to solve]

In the conventional method, when the culm to be threshed is wet with dew or rainwater, so-called wet threshing, the processed material flies inside the thrower cylinder by being released by the thrower, and the processed material is Due to the humidity of the water, it adhered to the thrower tube, making it easy for insufficient conveyance and clogging to occur.

The purpose of the present invention is to reprocess the second processed material from the sorting section and return it to the upstream side of the sorting section, so that it can be reprocessed efficiently, and furthermore, at the lowest possible cost, and even during wet threshing. The object is to be able to obtain the product in a state where transportation defects are less likely to occur.

[Means for solving problems]

The characteristic configuration of the threshing sorting device according to the present invention is that a vertical screw conveyor transports the second processed material from the sorting section to a point directly above or close to the receiving point and at the same level as the upper part of the sorting section. At the same time, a reprocessing section for the No. 2 processed material from this vertical screw conveyor is provided at a location on the upper side of the processing material transfer direction of the sorting section, through which the reprocessing material is passed through the inner space of the sorting section by releasing the reprocessing rotor. and the reprocessing rotating body is connected to the vertical screw conveyor in a state where it rotates around the same or almost the same axis as the screw axis of the vertical screw conveyor, and A discharge restricting device is provided to prevent the vertical screw conveyor from discharging the processed material toward the material discharge port, and its functions and effects are as follows.

[For production]

Even if the No. 2 processed material is wet, it is lifted to the reprocessing section and reprocessed while being pushed by the vertical screw conveyor so that it is unlikely to remain attached to the transport cylinder. This allows the material to pass through the internal space of the sorting section and be transferred to the upstream location of the sorting section while preventing it from adhering to the path wall, as would be the case when passing through the transport cylinder.

The second processed material supplied from the vertical screw conveyor to the reprocessing section is discharged toward the processed material discharge port, and is discharged from the reprocessing section without being processed by the reprocessing rotor at all or very little. This can be suppressed by the discharge regulating device. In other words, the vertical screw conveyor is designed to supply the processed material as much as possible to the inner cylindrical area of the reprocessing section, where the degree of action of the reprocessing rotating body is as large as possible in view of the rotational direction of the reprocessing rotating body and the position of the processed material discharge port. Therefore, it is possible to adjust the processing in the reprocessing section so that it is performed as efficiently as possible.

Compared to a structure in which the No. 2 processed material is conveyed from the extraction point of the sorting section to the action start end of the handling chamber or the upstream point of the reprocessing chamber, a screw conveyor, which has a shorter conveyance distance, is used in the sorting section. By just using a screw conveyor as the vertical screw conveyor, which does not require transport from the rear side of the machine to the front side, it can be lifted directly or almost directly above the level above the reprocessing section from the extraction point. The second processed material can be reprocessed and returned to the upper part of the sorting section.

〔Effect of the invention〕

Through the actions of the vertical screw conveyor, the reprocessing section, and the free transfer of the reprocessing rotor, the second processed material from the sorting section can be reprocessed and returned to the upstream side of the sorting section. Even in the case of wet threshing, the action of the vertical screw conveyor and the free transfer through the internal space of the sorting section makes it easier to avoid conveyed items from sticking or remaining stuck in the middle of the route, thereby preventing conveyance defects such as clogging. It has become less likely to occur, and work can now be done more efficiently.

Moreover, the effect of the discharge control device has made it possible to increase the processing efficiency in the reprocessing section, and the work has become more efficient in terms of the reprocessing of the second process material.

Furthermore, since the relatively expensive vertical screw conveyor can be used as a small conveyor with a short conveyance distance, it is economically advantageous as much as possible.

[Example] As shown in FIG.
) is configured to thresh the grain. Handling room (
2) through the receiving M (4) and the dust outlet (5) are transferred in the direction of the rotation axis of the handling cylinder by the swinging sorting device (6), while ) is applied to separate the grains and dust, and the dust is sucked together with the sorting air by a rotating fan (8) and discharged to the outside of the machine. This constitutes a sorting section. and a first horizontal screw conveyor (9) that carries out the first processed material from the sorting section to one side of the machine;
A second horizontal screw conveyor (10) for conveying the second processed material from the sorting section to one side of the machine body is provided at the bottom of the sorting section, thereby forming a threshing and sorting device for a combine harvester.

As shown in FIG. 2, the second horizontal screw conveyor (
A vertical screw conveyor (12) is connected to the conveyance terminal end protruding from the threshing machine side wall plate (11) of 10), and a reprocessing section (13) is connected to the conveyance terminal end of the vertical screw conveyor (12). Connect it. The vertical screw conveyor (12) receives the second processed material from the second horizontal screw conveyor (10) by a screw (12a) driven by the power transmitted from the second horizontal screw conveyor (10). The material is lifted to a location directly above or close to the location and at the same level as the upper part of the sorting section, and is knocked out using a plate blade (14) attached to the screw shaft (12b) so as to rotate integrally therewith. It is configured to be sent to the reprocessing section (13). As shown in FIGS. 1 and 2, the reprocessing section (13) is arranged so that a part of the threshing machine side wall plate (11) passes through the threshing machine side wall plate (11) and enters the inside of the machine. and a processing case (15) attached to the vertical screw conveyor (12)
In addition to forming a processing chamber, a reprocessing rotating body (16) as shown in FIG. 3 is attached to a screw shaft (12b) so as to be driven by a vertical screw conveyor (12). The second processed material fed into the processing chamber from the vertical screw conveyor (1
The inside of the processing case (15) is struck by the plurality of processing teeth (16a) of the reprocessing rotor (16) that rotates around the same or almost the same axis as the screw axis (P) in 2). The reprocessing material is handled while being rotated in the rotational direction (A) along the circumferential surface, and the reprocessed material that has become single granules and dust is released through the processing teeth (16a) of the reprocessing rotor (16). is discharged from the discharge port (I7) and the internal space (S) of the sorting section.
), the material is transferred to a location located on the upper side of the sorting section in the direction of material transfer through the portion located between the threshing machine side wall plate (11) and the receiving net (4).

In short, the second processed material from the sorting section is transported to the reprocessing section (step 3) by the second horizontal screw conveyor (10) and the vertical screw conveyor (step 2), where it is handled and processed again. The reprocessing rotor (16) throws the particles through the sorting section and towards the front of the aircraft, and the oscillating sorting device (6)
The particles are allowed to fall to an upstream location where they are separated into single particles and dust. Also during wet threshing, the second horizontal screw conveyor (10) and the vertical screw conveyor (
By the pushing action of 12) and the free transfer through the internal space (S) of the sorting section, consideration is given to ensuring that the processing is carried out in a state in which the processed materials are unlikely to remain attached to the conveyance path.

As shown in FIGS. 1 and 2, the screw case of the vertical screw conveyor (12) is provided with a wall portion forming a discharge control device (19) for the vertical screw conveyor (12), and the reprocessing The aim is to improve the processing efficiency in the section (13). That is, the emission control device (19) is
The height protruding into the processing case (15) and the discharge port (
17), the vertical screw conveyor (
12) suppresses the discharge of the second processed material toward the discharge port (17), and the reprocessing rotor (16) is ) is configured so that the processing material is supplied from the vertical screw conveyor (12) to the cylindrical part of the processing chamber where the degree of action is maximized.

[Another example]

In the reprocessing section (13) shown in FIGS. 5 and 6,
The efficiency of the re-handling of the No. 2 processed material is improved by using both the processing tooth (16a) of the reprocessing rotor (16) and the fixed tooth (step 8) that is fixed to the processing case (15). It is configured so that it can be used while In addition, the discharge control device (19) is formed so that its height is low compared to the height of the reprocessing chamber,
The structure is such that the smaller the amount of the No. 2 processed material supplied by the vertical screw conveyor (12) per unit time, the higher the reprocessing efficiency becomes. In other words, if the amount of husks supplied to the threshing section per unit time is below the designed maximum amount, the larger the supply amount, the more the second processing material from the sorting section will be, and the higher the threshing efficiency will be. As a result, the unprocessed state of the No. 2 processed material is brought to a state where only a relatively weak reprocessing effect, which can be obtained by the swing sorting device (6), is applied. Therefore, when the supply amount is large, the No. 2 processed material supplied from the vertical screw conveyor (12) to the reprocessing section (13) passes above the discharge control device (19) and passes through the discharge port (17).
), the amount of processed material that will be completely (or only slightly) reprocessed by the reprocessing rotor (16) and immediately discharged will be larger than when the supply amount is small, and the reprocessing rotor (16) will Care was taken to prevent grain damage caused by the strong reprocessing effect provided by (16).

The rotational force of the vertical screw conveyor (12) is transferred to the reprocessing section (1
3) may be implemented by providing a speed increasing mechanism between the two for transmitting speed increase.
