Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, an arc-shaped receiving net disposed along the lower side of the handling cylinder is integrally formed of a resin material, and the receiving net is a circle of the handling cylinder. The present invention relates to a threshing device equipped with a net oscillating device for forcibly oscillating at a set stroke along the circumferential direction.

[Conventional technology]

As a threshing device equipped with the net-receiving vibrating device, as in the conventional one disclosed in Japanese Utility Model Laid-Open No. 1-84548, the front and rear arc-shaped sides of the net are supported by guides in the circumferential direction of the handling cylinder. There is known a structure in which a receiving net vibrating device is configured to be capable of vibrating along and to be vibrated along the guide net and forcibly vibrating the receiving net along a guide.

Further, the above structure is inherited even in the case where the receiving net is integrally formed of a resin material.

[Problems to be solved by the device]

Vibration-driven resin nets are lightweight, easy to manufacture, and have the advantage that straw dust, etc. does not easily adhere, and even if they adhere, they can be peeled off relatively easily. However, on the other hand, since it is weak in strength, it tends to be bent and deformed downward, and it becomes remarkable due to forced vibration, so there is room for improvement in strength.

The present invention aims to rationally reinforce a resin-made net that vibrates forcibly.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is a threshing device described at the beginning, in the outer peripheral surface of the net, a long plate along the axis of rotation of the handling cylinder, and a vertical plate toward the axis. A reinforcing member having a shape of a fixed shape is arranged in a state of being in contact with the receiving net, and the reinforcing member is arranged so as to cross a leakage region of the receiving net by vibrating movement of the receiving net. Is a characteristic configuration.

[Action]

According to the above construction, the reinforcing member prevents the receiving net from flexing and deforming downward, and when the receiving net vibrates, the reinforcing member is a vertical plate and relatively slides while contacting the outer peripheral surface of the receiving net. As a result, the scraper action of scraping off the processed product leakage area of the receiving net, that is, the processed product that sticks into the receiving net and projects to the lower surface of the crosspiece is scraped off.

[Effect of device]

Therefore, the reinforcing member for making the resin-made net to be advantageous in strength can also exert the cleaning action of the outer peripheral surface of the net, so that the strength of the net can be rationally reinforced.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The basic configuration of the threshing device shown in FIG. 3 is well known in the prior art. The grain culm supplied into the handling room (2) is transferred to the handling barrel (1).
Rotate to thresh and leak from the net (3), and the threshed material with a lot of straw waste is discharged from the dust outlet (4) formed at the end of the handling chamber (2). These threshed products are supplied on a rocking sorting plate (5) and sorted into the first, second and dust in cooperation with the sorting wind generated in Kara (8) while giving a swing feed. To do. The first one is taken out of the machine by the first screw conveyor (6), the second one is conveyed to the lateral side of the machine by the second screw conveyor (7), and re-processed by the rotary blade type processing device (not shown). After that, it is returned to the feed end portion of the swing selection plate (5). Straw is discharged from the rear part of the machine body, and dust is sucked by a cross flow fan (9) and discharged to the outside of the machine.

The threshing net (3) of the threshing device is configured to forcibly vibrate at a set stroke along the circumferential direction of the handling cylinder (1) to prevent clogging. The receiving net (3) itself is formed by integral molding of ultra-high molecular weight polyethylene, which is excellent in wear resistance and water repellency, and the guide chamber (2) has arc-shaped guide members (10) at the inlet and outlet sides. , (11) are sandwiched from above and below and supported so as to be reciprocally movable in the circumferential direction of the handling cylinder (1).

As shown in FIG. 1, a receiving net vibrating device (12) for the receiving net (3) is provided on the back side of the handling room (2) and on the upper side. The vibration device (12) has an eccentric cam (14) attached to the rotating shaft (13),
One end of the swing arm (15) pivotally supported on the side wall of the handling chamber (2) is axially attached to the outer ring (16) of the eccentric cam (14) and engaged with the free end of the swing arm (15). A part (18) is provided for the construction. The engaging portion (18) engages with the roller (17) axially supported on the outer surface of the end of the receiving net (3), and the vibration of the swing arm (15) that moves downward by the rotation of the eccentric cam (14) is generated. It is transmitted to the receiving network (3). Power is transmitted from the input pulley (19) to the outside of the handling chamber (2) by the transmission belt (20) of the rotating shaft (13).

As shown in FIGS. 1 and 2, on the outer peripheral surface of the receiving net (3), a long shape along the rotation axis (P) of the handling cylinder (1),
Further, a reinforcing member (22) having a vertical plate shape toward the axis (P) thereof is fixedly arranged in a state of being in contact with the receiving net (3), and the reinforcing member (22) is provided with the receiving net. It is arranged so as to cross the leakage area (S) in the receiving net (3) by the vibration movement of (3).

Both ends of the reinforcing member (22) are attached to support frames (23) and (23) that support the guide members (10) and (11), and the lower surface of the receiving net (3) is attached to the receiving net (3). ) Does not warp.

The leakage area (S) is the receiving network (3).
(3C) and a large number of cross sections (3a) and (3b) arranged vertically and horizontally, and these cross sections (3a) and (3
Since the lower surface of b) and the reinforcing member (22) rub against each other due to the vibration of the receiving net (3), the processed objects attached to the crosspieces (3a) and (3b), particularly the crosspieces (3a) and (3b). A scraper action that removes the processed material attached to the edge facing the hole portion (3C) is generated, and the net (3) is reinforced by the reinforcing member (22) and also cleaned.

[Another embodiment]

As shown in FIG. 4, the reinforcing member (22) may have a vertically elongated shape in which the lower portion is bent to improve lateral rigidity.

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.
