Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a threshing device in which a receiving net is provided along the lower circumference of a handling rotary body.

[Conventional technology]

As a receiving net for a threshing device, a net such as a crimp net is generally reinforced with a strong frame, and the frame is fixed along the lower circumference of the rotating body.

[Problem that the invention seeks to solve]

However, most of the receiving nets with the above-mentioned structure are firmly attached during the manufacturing stage of the threshing equipment, and the attachment point to the machine body is difficult to see and difficult to reach. When the net is clogged, even if you try to remove the clog with a brush inserted into the handling chamber against the fixed receiving net, the brush cannot reach the clogged area or the brush becomes difficult to handle, making it difficult to remove the clog. In some cases, the work is difficult, and in that case, it is necessary to remove the receiving net from the aircraft body one by one and clean it, which is a very troublesome work to attach and detach each time.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to enable easy cleaning of a receiving net.

[Means for solving problems]

In order to achieve the above-mentioned object, the threshing device according to the present invention includes a plurality of threshing devices that are rotatable around an axis along the axis of the handling barrel, and are installed at multiple locations at predetermined intervals in the circumferential direction on the outer periphery of the handling chamber. sprockets are disposed, and pairs of the plurality of sprockets are provided in the upper and lower arms in the direction of transport of the threshed grain culms in the handling room, and the upper and lower arms are located in the upper and lower arms of the handling room. A band-shaped receiving net consisting of a chain wound around each sprocket and a net body detachable from the chain is wound over a plurality of sprocket pairs located at each pair, and the above-mentioned The net body is constituted by a molded net made of a resin material in which a core wire of a rigid material is embedded in the inside thereof along the transport direction of the threshed grain culm, and further, a guide member for guiding the movement direction of each of the chains, The present invention is characterized in that each of the chains is arranged along the outer periphery of the rotation locus of the handling cylinder.

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, when installing the receiving net in the handling room,
After a pair of chains are rotatably wound around multiple pairs of sprockets that are arranged in pairs in the direction of transport of the threshed grain culm in the handling chamber, the resin is The end of the mesh is fixed at one point on the chain, and the remaining parts are attached sequentially to the end as the chain rotates. Furthermore, when removing the net, one end of the net is removed from the chain, and then the net is sequentially removed as the chain rotates. Moreover, since the core wires are lined up in parallel in a direction perpendicular to the direction of transport of the threshed grain culms and embedded in a molded resin net, the wires can be easily moved between chains without impairing smooth circulation. In addition to suppressing the deflection of the net, the chain is arranged along the outer periphery of the rotation locus of the handling cylinder by means of a guide member, so the net can be firmly held in the operating position. The distance between the net and the handling teeth of the handling barrel is maintained at a predetermined state.

〔Effect of the invention〕

Therefore, according to the present invention, since the chain is first wound separately on the sprocket, installation is relatively easy, and once the chain is wound, the handling room is very small or complicated. The net can be easily attached and removed as long as there is a small gap within which the chain can be reached, and the performance of the net when attached is inferior to that of conventional nets because it is firmly fixed and supported. There is no. In particular, there is no need to disassemble the handling room to clean the receiving net, or to clean the narrow receiving net installation space. The work can be done relatively quickly and easily, and work efficiency can be improved.

〔Example〕

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

As shown in FIG. 4, a handling cylinder 3 is provided as a handling rotary body for threshing the grain culm conveyed into the handling chamber 2 by the feed chain 1, and handling teeth 4 are provided upright on the handling cylinder 3. A receiving net 5 for filtering the threshed material is stretched on the lower part along the tip trajectory of the threshing device. has been configured.

The sorting section A is located below the swinging sorting device 6 that receives the threshed material that is filtered by the receiving net 5 and falls.
A No. 1 product collection section 7 that collects the No. 1 product downstream, and a No. 2 product recovery section 8 that collects the No. 1 product, such as grains with branches, downstream, are provided behind it. Ta1
The second item collected in the second item collecting section 8 is transported to one side laterally via the second screw 10, and The grain is supplied from the end to the handling chamber 2 via the thrower 11 and threshed again.

As shown in FIG. 5, in the handling chamber 2, three shafts 12a, 12b, 12c are supported in the same direction as the axis of the handling cylinder 3.
Chain sprocket 13a, 13 is attached to each of c.
b and 13c are fitted as a set and in phase with each other. The upper chain sprocket 13c is fixed to both ends of a cylindrical member 15 having a large number of protrusions 14 on its outer circumferential surface for removing clogging of the receiving net 5.

As shown in FIG.
A pair of chains 16, 16 wrapped around
The ring plate 16a has protrusions 1 every few pieces.
7 is molded, and the flange 17 of the protruding piece 17
A can be used to connect the mesh body 5a with bolts. The net body 5a is formed by molding a flexible resin 18 such as urethane rubber into a band shape, and a core wire 19 of a rigid material is inserted inside the net body 5a in the direction of movement of the receiving net in the same direction as the axis of the handling cylinder 3. They are buried in a lined state, and square holes 18a are connected between each core wire as a mesh.
It is attached to a portion spanning the chain sprocket 13a on the a side. In addition, this part is formed in an arcuate shape so as to follow the outer peripheral edge of the rotation trajectory of the handling barrel 3 when viewed from the front, that is, the rotation trajectory of the tip of the handling tooth 4, and has a cross-sectional shape in the radial direction of the handling barrel 3. Two U-shaped guide members 20, 20 are arranged in parallel, and the second
As shown in the figure, the chains 16, 16 are engaged and guided so that the mesh body 5a follows the tip trajectory of the handling teeth 4. Note that 21 is a small guide member for preventing interference between the chains 16, 16.

As shown in FIG. 3, the shaft 12c of the cylindrical member 15 passes through the outside of the handling chamber 2 and is further bent to form a handle 22, which can be rotated. By chain 16,
Perform 16 circular rotations.

Therefore, when attaching the net 5a to the chains 16, 16, when the top plate 2b of the handling room 2 is swung open, one end of the net 5a is attached to the chains 16, 16, and then the handle 22 is turned. Move chain 1
6 and 16, and while inserting the cylindrical member 15 into the hole 18a of the net 5a, the net 5a is
This can be done by connecting the projecting piece 17 with bolts.

[Another example]

In carrying out the present invention, the flange 17a of the projecting piece 17 may be formed on the outside of the connecting shaft 23 of the link plate 16a, as shown in FIG. in this case,
Since the mesh body 5a is made of flexible resin, it is stretched at the rotating portions of the chain sprockets 13a, 13b, and 13c, and the hole 18a is enlarged. As a result, the clogging material becomes easier to fall off, and in combination with the cylindrical member 15 for clogging removal, an even better effect can be expected.

Note that the attachment of the net body 5a is not limited to bolt connection. Furthermore, although numbers are written in the claims section for convenient comparison with the drawings,
By virtue of this description, the invention is not limited to the structure of the attached drawings.
