Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a threshing device mounted on a combine, a harvester or the like, and more particularly to a support structure for a net.

[Conventional technology]

The receiving net is an arc-shaped one arranged along the lower side of the rotating handling cylinder, and the grain culms are threshed between the receiving net and the handling barrel, and the single-grained grains leak through the receiving net. During the threshing operation, this receiving net is generally fixed in the handling room.

[Problems to be solved by the invention]

In the threshing device, many grain culms are vigorously threshed between the handling barrel and the net, so single-grained grains and small straw scraps are apt to clog the eyes of the net. This caused a decrease in efficiency and grain collection efficiency.

Here, the present invention focuses on the above-mentioned problems, and an object thereof is to obtain a support structure for a net which can minimize clogging of the net during threshing work.

[Means for Solving the Problems] The feature of the present invention is that, in the threshing apparatus as described above, support members are provided at a plurality of outer surfaces of an arcuate receiving net, and guides having a substantially L-shaped cross section are provided. It is provided in the handling chamber with a length that extends over substantially the entire length of the receiving net, and a supporting member for the receiving net is placed on a guide to support and guide the receiving net so as to be movable along the circumferential direction on the lower side of the handling cylinder. In addition to providing a receiving net vibrating mechanism for forcibly vibrating the receiving net at a set stroke along the guide, in a guide portion other than the vibration range of the supporting member, an opening is provided in a corner portion at the inner back, The action and effect are as follows.

[Action]

As described above, when the net is forcedly vibrated in the circumferential direction of the handling cylinder, the so-called shaking effect causes grains and small straw debris clogging the eyes of the net to fall downward.

Further, in the guide having a substantially L-shaped cross section, since an opening is provided at the inner corner portion where straw dust or the like easily accumulates,
Straws and the like that have come to the corners drop downwards, and since this opening is not provided in the guide portion where the supporting member of the receiving net contacts and reciprocates, it supports the receiving net. It does not particularly reduce the strength of the guide portion.

Furthermore, since the opening is only a corner and the opposite end of the guide is connected, when the catching net is slid into the guide at the end of the disassembling work of the threshing device, the part where the supporting member of the catching net is connected to the guide Since it slides up, the receiving net can be moved to a predetermined position without trouble.

[Effect of device]

As described above, by vibrating the receiving net, clogging of the receiving net is reduced and threshing efficiency and grain collection efficiency are improved. In addition, even in the guide that supports the receiving net, a structure for preventing the accumulation of straw debris with a small decrease in strength can be obtained, and it is possible to smoothly drive the receiving net with vibration, and it is relatively easy to insert and remove the receiving net into the guide. A structure was obtained that could be done.

〔Example〕

Hereinafter, a threshing device which is an embodiment of the present invention will be described with reference to the drawings.

The whole threshing device is configured as follows. That is,
As shown in FIG. 5, the grain culms that have been conveyed in a sideways posture by the feed chain (1) are placed in the handling room in the threshing device.
Threshing is performed between the handling barrel (3) and the net (4) by the handling barrel (3) which is horizontally driven by (2). Threshed paddy and relatively small straw debris leaked through the net (4) located under the handling barrel (3), and the gren pan (6) was installed on the lower swing sorting frame (5). )
It drops on the upper side, and due to its swinging action, it is sent to the lower-side Glen Sieve (7) while being sorted with specific gravity, and then sent to the Glen Sieve (7).
Above, the paddy is leaked and collected by the No. 1 material collecting section (9) by the rocking action and the blowing action from the Kara (8). And 2
The rough rice with branches collected in the number collecting part (10) is sent to a processing chamber (not shown) from a throw-off type thrower (not shown), and is singulated into particles, and a rocking sorting frame (5) It is returned to the top.

Next, the receiving net (4) will be described in detail. As shown in FIG. 1, a pin (28) and a bracket (29) connectable to each other.
It has a structure in which a mesh (12) integrally formed of high molecular weight polyethylene resin is connected to the pair of metal arc-shaped netting frames (11) with bolts, and is supported at multiple places on the left and right of the netting frame (11). A roller as a member (13) is attached.

On the other hand, the side wall (16) of the handling room (2) is provided with a guide (14) for supporting the receiving net (4). As shown in the figure, this guide (14) has a substantially L-shaped cross section like a bent plate material and has a length substantially the same as the circumferential length of the net (4). It is fixed to the side wall (16) via a guide (15). Then, in a portion other than the roller (13) of the receiving net (4) is placed, an opening (14a) is provided at a corner portion of the guide (14), and a guide (14a) corresponding to this opening (14a) is provided. 1
The edge of 4) is also cut out. With the above structure, the receiving net (4) and the roller (13) can be moved in a range where the opening (14a) of the guide (14) is not provided, and the receiving net (4) is inserted from above. Open hole (14a)
The roller (13) above the area not provided with and the portion (14b) connecting the areas is guided. The auxiliary guide (15) is a guide for the receiving net (4).
It has the function of suppressing the rise from (14).

Next, the receiving net vibrating mechanism (17) for forcibly vibrating the receiving net (4) within the above range will be described in detail. As shown in FIG. 3 and FIG. The drive arm (18) pivotally supported around the axis (P ₁ ) is engaged and connected to the back surface of the net frame (11), and the horizontal axis (P ₂ ) An eccentric shaft (19) is provided which is driven to rotate around the eccentric shaft (19).
A ring member (20) is externally fitted to the bearing via a bearing, and a linking rod (21) is installed between the ring member (20) and the drive arm (18). With the above structure, when the eccentric shaft (19) is rotationally driven around the horizontal axis (P ₂ ), the drive arm
When the (18) is rocked, the receiving net (4) opens the hole (14
It is forced to vibrate within the range where a) is not provided.

As shown in FIG. 4, the engaging and connecting structure of the drive arm (18) and the net (11) is connected to the left and right brackets (22) on the rear of the net (11) by connecting pins (23). Is attached so that it can swing to the left and right, and both connecting pins (23)
The bearing (25) is attached to the tips of both connecting pins (23) by being urged to the left and right protruding sides by 4). With the above structure, the connecting pin (23) is slid and the bearings (25) of both connecting pins (23) are engaged with the tip of the drive arm (18), so that the receiving net (4) is moved to the drive arm. It is connected to (18).
Then, remove the tool rest (26) and pull out both connecting pins (23) from the drive arm (18) to remove the net (4) from the tool rest.
It can be pulled out from the (26) side.

[Another embodiment]

As shown in FIG. 6, it is also possible to adopt a structure in which inclined scrapers (27) are provided in front of and behind the roller (13). As a result, the scraper (27) scrapes off scraps and the like on the guide (14) while the receiving net (4) is being vibrated.

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.
