Abstract

PURPOSE:To prevent the clogging of a receiving plastic net placed along a threshing cylinder with a simple construction occupying a relatively small space, by providing the receiving net with an apparatus to apply a vibration to the net along the net face. CONSTITUTION:A receiving net 1 is made of a plastic to prevent the adhesion of wet straws and unhulled rice to the net by the water-repellency of the plastic. The receiving net 1 is divided into two sections along the circumference of a threshing cylinder 2 and the divided receiving nets 1a, 1a are supported on a net 19 in a manner freely movable along the rotational direction of the threshing cylinder 2. A tension spring 21 is attached to the top part of the receiving net 1a and elliptic cam plates 22 placed at regular intervals are made to contact with contact pieces 18 protruded from the lower end of the receiving net 1a. The receiving net 1a is vibrated by this construction.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a threshing device that allows continuous threshing work to be performed without clogging the receiving net in the handling room.

[Conventional technology]

When threshing husks that are damp due to rain or morning dew, paddy and straw debris tend to adhere to the receiving net through the water, so they tend to collect and clog the receiving net. be. Therefore, conventionally, as a receiving net structure of such a threshing device, as disclosed in, for example, Japanese Utility Model Application Publication No. 182230/1980, vibrations are applied to the receiving net by moving the receiving mesh body along the circumference of the handling trunk. It has also been proposed to use vibration sources to remove paddy, straw waste, etc. that are stuck in the mesh of the receiving net.

[Problem that the invention seeks to solve]

However, according to the above configuration, it is necessary to wind and drive the bendable endless belt-shaped receiving net between both rollers.
As the receiving net and its driving device have become more complex, the space for driving the receiving net has increased, leaving room for improvement. In addition, the applicant proposed that the receiving net itself be made of a resinous material to which wet processed materials do not easily adhere; If it is fed onto a receiving net all at once, even resin-made receiving nets may block the mesh and accumulate on this receiving net, and the effect of forming the receiving net with resin may be insufficient. there were.

The present invention has been made focusing on the above-mentioned circumstances, and
To prevent clogging in a receiving net and to perform continuous work even in wet threshing with a simple configuration and without taking up space.

[Means for solving problems]

That is, the characteristic configuration of the threshing device according to the present invention is that the resin receiving net disposed around the handling drum is provided with a device that applies vibration in the direction along the net surface, and its action is And the effects are as follows.

[For production]

Since the receiving net is made of resin, the water repellency of the resin makes it possible to prevent wet straw waste and paddy from adhering to the receiving net as much as possible. Even if the mesh of this resin catch net becomes clogged with straw waste or paddy through water, we have installed a device that vibrates along the surface of the catch net, so it will stop due to inertia. By rapidly moving the receiving net relative to the condition of the paddy, etc., it is possible to separate the paddy, straw waste, etc. from the receiving net.

〔Effect of the invention〕

As a result, in addition to making the receiving net made of resin and imparting water repellency, we also made the receiving net vibrate, so that the synergistic effect of the water repellency of the resin and the vibration of the receiving net caused
It is now possible to prevent wet rice and straw waste from clogging the mesh of the receiving net, and the structure is relatively simple compared to the conventional case of rotating the receiving line, and it does not take up much space. , it became possible to perform continuous work even in wet threshing.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figure 2 shows a threshing device mounted on a combine harvester. In this threshing device, a handling barrel (2) is hung horizontally in a handling chamber (6) in which a receiving line (1) is stretched at the lower part, and the tip of the threshing husk is placed in this handling chamber (6). A feed chain (3) is provided which clamps and conveys the shell culm stock along the rotational axis of the handling cylinder with the culm inserted, and the waste reduced from the light w4 (1) and the reduced material in the handling chamber (6) are provided. It is constructed by providing a sorting section (8) for sorting out objects falling from a dust inlet (7) formed at the end of the conveyance.

The sorting section (8) includes a swinging sorting device (9) that sorts the materials to be processed from the handling room (6), and a sorting fan (10) that sends sorting air to the swinging sorting device W (9) from the front. , a first item collecting section (11) that collects the sorted first item, and a second and first item collecting section (12) that collects the second item. The swinging sorting device (9) includes a pair of left and right swinging sorting plates (14).
) over Glenpan (16) and Glensheep (5)
and two upper and lower stroke racks (15), (15) for swinging and sorting the processed material falling from the dust inlet (7) of the handling chamber (6). ing.

Next, said light! To explain the structure of (1) in detail, as shown in Fig. 1, the light M4 (1) is integrally molded from ultra-high molecular weight polyethylene.
(1) is divided into two parts along the circumference of the handling cylinder (2), and each divided receiving net body (1a), (1a) is placed on the handling cylinder on the net body (19) arranged below. (2) It is supported so as to be movable along the rotational direction.

That is, a locking piece (17) is inserted from the bottom surface of each receiving net body (1a).
and a contact piece (18) are provided integrally protruding downward, respectively,
A tension spring (21) is provided at the upper end of the receiving net body (1a).
A drive shaft (23) is attached to the contact piece (18) protruding from the lower end of the fertilization body (1a).
An elliptical cam plate (22) driven and rotated around the cam plate (22) comes into contact at appropriate intervals, and the drive of the cam plate (22) causes the receiving net body (1a) to be moved by the biasing force of the spring (21). It is forcibly moved toward the center against the

Therefore, by rotationally driving the cam plate (22), the cam plate (
22) comes into contact with the contact piece (18), the receiving net body (1a)
is subjected to strong impact force, and this cam plate (
22), the receiving net body (1a) is driven by the spring (21).
) moves slightly toward the center against the biasing force of A receiver piece (20
) by the locking piece (17) locking the receiving net body (1
In a), the vehicle will be subjected to a relatively strong collision force.

The drive directions of both receiving net bodies (1a) and (1a) are set in opposite directions, so the drives of both receiving net bodies (1a) cancel each other out, causing large vibrations in the threshing device as a whole. It does not occur.

The moving device (24) prevents the movement of the receiving net body (1a) by the cam plate (22) and the collision between the locking piece (17) and the receiving piece (20) due to the return urging force of the tension spring (21).
). Further, the rotation speed of the cam plate (22) and the biasing force of the tension spring (21) can be adjusted, and when the rotation speed of the cam plate (22) is increased, the cam plate (22) When colliding with the contact piece (18) of the net (1a), the receiving net (1a) will receive strong vibrations, and on the other hand, if the tensile force of the tension spring (21) is increased, When the stop piece (17) and the receiving piece (20) collide, the receiving net body (1a) is subjected to strong vibrations.

[Another example]

The above-mentioned threshing device can also be mounted on a harvester.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
