Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a second reducing device for a threshing machine configured to reprocess and then reduce the second selected product.

[Conventional technology]

As such a threshing machine, for example, as shown in Japanese Utility Model Laid-Open No. 59-29158, a second device reducing lifting device is configured as a thrower type, and the thrower blades are provided with processing teeth, so that It is known that a rough treatment of the second product is performed at the time of forced throwing.

[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 it is possible to surely reprocess and reduce a strongly entangled second object or a wet second object, as well as a reprocessing function unit. It is an object of the present invention to provide a second reducing device for a thresher capable of easily adjusting the above.

[Means for solving problems]

The characteristic configuration of the present invention is that the end of the second transverse feed screw is
The processing rotor is provided with the processing teeth projecting, and a second lifting screw conveyor for lifting and reducing the processed product sent out by the processing rotor is provided, and a processing case containing the processing rotor is provided. An opening for maintenance is formed on the peripheral surface, and a lid for opening and closing the opening is configured to be positionally adjustable in the axial direction of the processing rotary body, and the tooth receiving member provided on the inside of the lid and The rotation locus of the treatment tooth is made to overlap in the axial direction view, and a gauge insertion hole for measuring the gap between the receiving tooth and the treatment tooth is formed in the lid body.・ The effects are as follows.

[Action]

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 second material sent by the second horizontal feed screw is re-processed in cooperation with the processing tooth and the tooth receiving projecting inside the lid, and is sent to the starting end of the second lifting screw conveyor. In this case, since the tooth traces and the rotation trajectories of the treated teeth overlap when viewed in the axial direction, even if the second product is moist and becomes a lump, it can be sufficiently disentangled and separated to provide an effective singulation effect. Is added.

Then, the re-processed second product that has been sent is forcibly lifted and reduced by the second lifting screw conveyor that is less susceptible to the adhesion of the second product.

When the distance between the tooth receiving and the rotation locus of the processing tooth is not appropriate, the processing rotating body is stopped and a gauge is inserted through the hole of the lid to measure the gap between the tooth receiving and the processing tooth. The lid is positionally adjusted in the axial direction of the processing rotary member so that the interval is optimal.

[Effect of device]

 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.

Sufficient processing and pumping functions can be exhibited even for wet crops.

By using the lid provided in the opening for maintenance, the tooth receiving member can be easily installed at an appropriate position with respect to the processing tooth, and a good processing function can be exhibited.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 9 shows a threshing machine including a threshing section (A), a sorting section (B) and a collecting section (C).

The threshing section (A) is one in which the handling barrel (2) is mounted in the handling chamber (1) and the receiving net (3) is stretched along the lower side of the handling barrel (2). The grain culms pinched and conveyed by the chain (4) are processed by the handling cylinder (2), and the processed product is leaked and supplied onto the sorting section (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 rocking sorting device (5) is provided with a Glen pan (8) and a Glen sieve (9) in front and back in a continuous state across both sides of a frame body (7) that can be rocked and driven, and a straw in two upper and lower stages. The racks (10) and (11) are provided at the front and the rear. Then, the processed product leaked from the receiving net (3) is received by the Glen pan (8),
After the specific gravity difference is selected, it is oscillated and transferred to the rear Glensieve (9), and then it is oscillated and transferred rearward while selecting the leakage by the Glensive (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 FIGS. 3 and 4, 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, and Six processing teeth (16) are attached to each of the rotating blades (15) at equal intervals in the axial direction, and the processing blade (15) and the processing teeth (16) constitute a processing rotating body (D). ing. 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 rotation direction, and is a second tool sent by the second screw (14a). While handling, handle and process to make a single grain. Further, the outer diameter of the loose blade (15) is smaller than that of the treated tooth (1
It is a plate body of about two-thirds of the outer diameter of 6), hits the second object to make it further into single particles, and the ejection action causes it to pass through the inside of the connecting case (18) described later and the second lifting screw Send to the beginning of the conveyor (20).

As shown in FIG. 6, a connecting case (18) with a forward spread is connected to the front side of the processing case (17) in which the processing rotating body (D) is housed, and an outlet ( The starting end of the second lifting screw conveyor (20) is connected to 19).

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) is inserted is formed in the lid body (22) as a long hole along the axial direction, the position in the closed state can be adjusted to move in the axial direction. It is. That is, the interval between the processing tooth (16) and the tooth receiving (24) described later can be adjusted to an optimum distance by loosening the bolt hole (23a) and moving the lid body (22). Of.

Specifically, as shown in FIGS. 1 and 2, the lid (22)
Two holes (22a) for insertion of gauges are formed in both sides of the upper part in the circumferential direction, and a gauge plate (28) is inserted into each of these holes (22a).

The bolt (23a) is located at a position where the two gauge plates (28) come into contact with the processing teeth (16) and the receiving teeth (24), in other words, at a position where the receiving teeth (24) enter the clearance between the processing teeth (16). Tighten to fix the lid (22) and remove the gauge plate (28).

The hole (22a) after removing the gauge plate (28) is covered with a cover (29) so that the second object will not get wet, and the nut is tightened.

As shown in FIG. 5, 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 about 90 degrees, which is slightly smaller than the clearance angle (α) of the treated tooth (16). In addition, the lowermost tooth (24) is the processing case
It is about 40 degrees above the lowest point in (17).

The connecting case (18), the rotary vane (15) is the starting end of the second lifting screw conveyor (20) for the reprocessed second object sent from the processing case (17) by 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.
The joint angle (γ) between (18a) and the second lifting screw conveyor (20) is smaller than 90 degrees, and the width of the discharge port (19) is second lifting as shown in FIG. The diameter is made larger than the diameter of the feeding screw conveyor (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 (18a)
The length ( ₂ ) of b) is quite short, actually about 20 mm.

The second lifting screw conveyor (20) has a screw (26) inside the lifting cylinder (25), and a discharging blade (27) provided at the upper end of the screw (26) is lifted by the lifting cylinder (25). ) Is seen through the second return port (25a) on the lateral side of the upper end, and as shown in FIG. 8, after the second product sent through the connecting case (18) is pumped, the discharge blade (27) Reduces from the second reduction port (25a) onto the sorting section (B).

As explained above, in the second reducing device of the threshing machine according to the present invention, all the second products sent by the second transverse feed screw (14a) are arranged in the processing teeth (16) and the staggered pattern. Separated while fully unraveling due to the interaction of the tooth receiving (24), it becomes a single grain, and while it is further granulated by the impact of the rotating blade (15), it is sent to the second lifting screw conveyor (20) and lifted. It is to send back.

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.

Furthermore, since the distance between the tooth receiving (24) and the rotation locus of the processing tooth (16) can be adjusted easily and accurately, it is possible to always keep the state suitable for reprocessing.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
