Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a No. 2 reduction device for a thresher that reprocesses No. 2 recovered in a sorting unit and then reduces the No. 2.

[Conventional technology]

Examples of the second reducing device for such a thresher include,
-29158, as shown in Japanese Patent Publication No. 29158, the feeding device for reducing the second product is configured as a thrower type, and by providing processing teeth on the thrower blade, the rough treatment of the second product is performed at the time of forced throwing by the thrower blade. What is configured to do is known.

[Problems to be solved by the device]

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 a situation, and it is the second reduction of a threshing machine that can surely and properly reprocess a strongly entangled second thing or a wet second thing. The purpose is to provide a device.

[Means for Solving the Problems]

The characteristic configuration of the present invention is that the end of the second transverse feed screw is
A processing rotator with protruding processing teeth is arranged, and a receiving tooth is provided on the inner peripheral surface of a processing case in which this processing rotator is provided.
A second lifting screw conveyor for lifting and reducing the processed product sent by the processing rotor is provided, and a rotary blade facing in the circumferential direction is provided at the root side of the processing tooth, and the side edge on the starting end side of the rotary blade is provided. The part is connected to the terminal edge of the No. 2 transverse feed screw, and its action and effect are as follows.

[Action]

In other words, at the end of the No. 2 horizontal feed screw, the processing rotary body with the processing teeth protruding is provided in place of the thrower blade, so the No. 2 object sent by the No. 2 horizontal feed screw is the processing teeth and processing case. It is separated while being unraveled in cooperation with the teeth that are projected on the inner peripheral surface, and becomes a single grain, and is further made into a single grain by the impact of the rotating blades, and then to the starting end of the second lifting screw conveyor. Sent out. In this case, since the side edge of the rotary blade on the No. 2 transverse feed screw side is connected to the end edge of the No. 2 transverse feed screw, the No. 2 article conveyed by the No. 2 transverse feed screw is smoothly transferred into the processing case. In addition to being able to be sufficiently affected by the processing teeth and the rotating blades, the mixed straw is difficult to wind around the shaft of the No. 2 transverse feed screw.

Next, the second product sent out from the processing case is forcibly pumped and reduced by the second lifting screw conveyor that is not easily affected by the adhesion of the second product.

[Effect of device]

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

By providing the processing teeth that rotate in the processing case and the fixed receiving teeth, it is possible to effectively reprocess the second product while suppressing an increase in the size of the threshing device as compared with the case where the processing cylinder is provided.

Since the second product whose fluidity has been increased due to the single grain formation by the reprocessing is sent out from the processing case, the second product is less likely to be clogged between the processing case and the second lifting screw conveyor.

Since the second product whose fluidity has increased due to re-processing into single granules is pumped and reduced by the second lifting screw conveyor, it is possible to smoothly perform the pumping and reduction, and to compare it directly with the conventional lower blades. Thus, even if the rotation speed of the processing rotator is lowered, the second product sent by the rotary blade is unlikely to stall, and the second product can be reliably returned.

Since the rotary blades are connected to the end edge of the No. 2 horizontal feed screw, the second product flows smoothly from the end of the No. 2 horizontal feed screw into the processing case, and reprocessing is effective without retention at the processing case inlet. Can be done.

Sufficient processing function and lifting function even for wet crops by combining the structure that effectively reprocesses the second product with treated teeth and fixed receiving teeth and the second lifting screw conveyor Can be demonstrated.

As shown in FIGS. 1 and 2, four rotary blades (15) facing in the circumferential direction are provided at intervals of 90 degrees at the rear end of the second transverse feed screw (14a). At the same time, six processing teeth (16) are attached to each of these rotary blades (15) at equal intervals in the axial direction, and the processing rotor (D) is formed by these rotary blades (15) and processing teeth (16). Are configured. 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). It is solved and reprocessed to make a single grain. The outer diameter of the rotary blade (15) is 3 times the outer diameter of the processing tooth (16).
It is a plate body of about 2/2, and while the second product is hit and further granulated, the second lifting screw conveyor is passed through the connecting case (18) described later by the hammering action.
Send to the beginning of (20).

Further, one of the four rotary blades (15) has a side plate (15a) on the side of the second horizontal feed screw (15a) at the end edge of the second horizontal feed screw (14a) with a guide plate (28). ), And smoothly guide the second object sent by the second transverse feed screw (14a) into the processing case (17) to

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 (24) described later can be adjusted to an optimum distance by moving the lid (22).

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 about 20 degrees, which is slightly smaller than the clearance angle (α) of the treated tooth (16). In addition, the lowermost tooth receiving (24) is the processing case (1
It is set about 40 degrees above the lowest point of 7).

The connecting case (18) is a starting end of the second lifting screw conveyor (20) for the reprocessed second object that has been punched 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.
