JPH0612966B2 - The second reducing device of the thresher - Google Patents

Description

TECHNICAL FIELD The present invention relates to a second reducing device for a thresher, which is configured to reprocess and then reduce the second selected product.

[Conventional technology]

As such a thresher, for example, as shown in Japanese Utility Model Laid-Open No. 59-29158, the second reduction pumping device is configured as a thrower type, and the thrower blades are provided with treated teeth.
It is known that the rough treatment of the second product is performed when the throwing blade is forcedly thrown.

[Problems to be solved by the invention]

This configuration is intended to re-process the second object with the processing teeth (protrusions for scraping) provided on the front surface of the thrower blade, but the processing function is insufficient and especially for the second object with strong entanglement. On the other hand, the unwinding function was hardly exhibited.

Further, during wet threshing, it was difficult to carry out sufficient landing and lifting, and the product was likely to be clogged.

The present invention has been made by paying attention to such an actual situation, and the second reduction of a threshing machine capable of reliably reprocessing and reducing the second matter wet with the second one having a strong entanglement. The purpose is to provide a device.

[Means for solving problems]

The characteristic configuration of the present invention is that the end of the second traverse screw is
A processing rotary body having processing teeth protruding is provided, and a second horizontal feeding screw conveyor for hoisting and reducing the processed material sent by the processing rotary body is provided, and a processing case of the processing rotary body is provided. Projecting teeth on the inner peripheral surface,
A peripheral wall that prevents the second product immediately after flowing into the processing case from being short-circuited to the second lifting screw conveyor and provided at the second lateral feed screw side portion in the outlet portion of the processing case is provided. .

[Work]

That is, at the end of the No. 2 transverse feed screw, a processing rotating body having processing teeth protruding is provided in place of the lower blade,
The No. 2 horizontal feed screw is used to feed the No. 2 object into the processing case in cooperation with the processing teeth and the receiving teeth protruding from the inner surface of the processing case, and separates and reprocesses. Send to the beginning of the lifting screw conveyor. When the second product enters the processing case, part of the second case tries to be sent by short-circuiting the second lifting screw conveyor of the processing case. It is blocked by the peripheral wall provided, and after being reprocessed by the treated teeth and the tooth reception, it is sent to the second lifting screw conveyor.

Next, the re-processed second circle and second circle sent out from the processing case are forcibly lifted and reduced by the second lift screw conveyor, which is unlikely to be affected by the adhesion.

〔The invention's effect〕

 According to the present invention, the following effects are brought about.

The second tooth can be effectively reprocessed by the processing tooth rotating in the processing case and the fixed tooth receiving.

The re-processed second product is sent out from the processing case and is then pumped and returned by the second lifting screw conveyor, so that the second product is clogged between the processing case and the outlet of the second lifting screw conveyor. Is less.

The peripheral wall provided at the outlet of the processing case prevents the second object immediately after entering the processing case from short-circuiting and coming out of the processing case, so that the second object can be reliably reprocessed by the processing tooth and the tooth receiving.

It is possible to exert sufficient processing function and pumping function even in wet operation.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 7 shows a threshing machine including a threshing section (A), a sorting section (B) and a collecting section (C).

The threshing part (A) is a one in which the handling barrel (2) is mounted on the handling chamber (1) and the receiving net (3) is stretched along the lower side of the handling barrel (2). The grain culm held and conveyed by the chain (4) is handled by the handling cylinder (2), and the treated product is leaked and supplied onto the sorting (B).

The sorting section (B) includes a swing sorting device (5) and this swing sorting device.
It consists of Kara Minou (6) that sends sorting wind to (5). The swing selecting device (5) is provided with a Glen pan (8) and a Glen sieve (9) in a series of front and back over both sides of a frame body (7) which can be driven to swing, and also has a two-pronged straw rack. (10) and (11) are provided at the front and rear. Then, the processed product leaked from the receiving net (3) is received by the Glen pan (8),
After the specific gravity difference is sorted, the latter is oscillated and transferred to the rear Glensieve (9), and then the latter is oscillated and transferred to the rear while the leakage is sorted by the Glensieeve (9), and is dropped and discharged from the rear end. On the other hand, the processed material discharged from the dust inlet (1a) of the handling room (1) is treated with the upper straw rack.
It is received by (10), swings backward while sorting for leakage, discharges to the lower Straw rack (11), again leaks sorted by the lower Straw rack (11), and discharges from the rear end to the outside of the machine. To do.
Incidentally, (12) is a dust-exhausting fan for discharging straw dust together with the sorting wind to the outside of the machine.

The recovery part (C) is the first item recovery part (13) for recovering the paddy that has leaked from the Glensive (9), and is discharged from the rear end of the Glensive (9) or the straw rack (10), (11). ) And a second crop recovery unit (14) for recovering branched rice and the like. In the first item recovery section (13), the first horizontal feed screw (13a) for conveying the recovered first item to the one horizontal side, and in the second item recovery section (14), A second transverse feed screw (14a) is provided to convey the second workpiece laterally to one side.

As shown in FIG. 1 and FIG. 2, four rotary vanes (15) facing in the circumferential direction are provided at the end of the second transverse feed screw (14a) at intervals of 90 degrees. Rotary vane
Six processing teeth (16) are attached to each of the (15) at equal intervals in the axial direction, and the processing blade (15) and the processing teeth (16) form a processing rotating body (D). . The processing tooth (16) is a blade shape having a clearance angle (α) slightly larger than 20 degrees at the edge on the lower side in the rotational direction, and is fed by the second transverse feed screw (14a). While unraveling the food, it is processed and made into single grains. The outer diameter of the rotary vane (15) is the treating tooth (16).
It is a plate body of about two-thirds of the outer diameter of No. 2, and the second object is impacted to make it into a single particle, and its ejection action causes the second No. Send to the beginning of 20).

As shown in FIG. 4, the connecting case (18) with a forward spread is connected to the outlet provided on the front side of the processing case (17) in which the processing rotating body (D) is housed. The starting end of the second lifting screw conveyor (20) is connected to the discharge port (19) of 18).

The treatment case (17) has an arc shape along the locus of the tip of the treatment tooth (16), and a maintenance opening (2
1) has been formed. This opening (21) is usually the processing case.
It is closed by a lid body (22) which is bolted to (17), and when necessary, it can be easily opened by removing the bolt (23a) and removing the lid body (22).
Since the bolt hole (23b) through which the bolt (23a) passes is formed in the lid body (22) as a long hole along the axial direction, the position in the closed state can be moved in the axial direction. ing. That is, the distance between the processing tooth (16) and the tooth receiving portion (24) described later can be adjusted to an optimum distance by moving the lid body (22).

In addition, the second side feed screw (14
The side wall (17a) on the a) side is provided with an arcuate peripheral wall (28) along the outlet of the processing case (17). As a result, the second object immediately after being conveyed to the processing case (17) by the second screw (14a) is the side wall (17a) and the processing tooth closest to this.
It is designed so as to be prevented from directly entering the connecting case (18) through the gap (S) with the (10). In short, all the second irons conveyed are sufficiently capable of undergoing the unraveling action and the singulation action of the treatment tooth (16).

As shown in FIG. 3, the teeth (2
4) are planted in a zigzag pattern and are inserted into the gap of the rotation locus of the treated tooth (16). The tooth receiving (24) is for assisting the processing tooth (16) to unravel the second material that has been sent into a single grain, and the processing tooth (16 The clearance angle (β) is formed in the same manner as By the way, this clearance angle (β) is
It is about 20 degrees, which is slightly smaller than the clearance angle (α) of the treated tooth (16). The lowermost tooth receiving portion (24) is provided about 40 degrees above the lowermost point of the processing case (17).

The connecting case (18) is a starting end of the second lifting screw conveyor (20) for the second object that has been reprocessed and has been sent out from the processing case (17) by the rotating blades (15) and the processing teeth (16). The upper side surface (18a) is longer than the lower side surface (18b) and has a tubular shape. Also, as shown in FIG. 4, the joint angle between the upper side surface (18a) and the second lifting screw conveyor (20)
(γ) is smaller than 90 degrees, and as shown in Fig. 5, the width of the discharge port (19) is set to the second lifting screw conveyor.
The diameter is made larger than the diameter of (20) by L so that the second product can be smoothly supplied to the second lifting screw conveyor (20). Further, the inner peripheral surface of the connecting case (18) is coated with a water-repellent substance so that a damp second object is unlikely to adhere thereto. In addition, the lower side surface (18b) with respect to the upper side surface (18a)
The length (l ₂ ) is quite short, actually about 20 mm.

The second lifting screw conveyor (20) has a screw (26) inside the lifting cylinder (25), and a discharge blade (27) provided at the upper end of the screw (26) is lifted by the lifting cylinder (25). ), Which is viewed through the second return port (25a) on the side of the upper end of the connection case (18).
After the second item sent through the
By 7), it is reduced from the second reduction port (25a) to the sorting section (B).

Further, a downflow port (25a) is formed on the upper side wall of the lifting tube (25), and the downflow port (25b) and the first object recovery section (13) are connected by a downflow tube (29). I am doing it. And the outlet (25b)
By opening the shutter (30) provided in the, the second item being pumped can be poured into the first item recovery section (13). If the second item is dry and can be fully reprocessed, open the shutter (30).

As described above, the second reducing device of the threshing machine according to the present invention is the second tooth sent by the second horizontal feed screw (14a) and the receiving tooth arranged in the zigzag with the processing tooth (16). tooth
(24) is sufficiently separated by the interaction of the particles, and the particles are made into single particles, and while being blown into particles by the impact of the rotating blades (15), they are sent to the second lifting screw conveyor (20) to be lifted and reduced. It is a thing. Therefore, even when wet threshing, it is difficult for the moistened second product to become lumps into single granules or to adhere to the inside of the feeding route, which makes feeding difficult. It can be reliably pumped and reduced after being reprocessed.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the attached drawing structure by the entry.
