The present invention relates to a threshing apparatus mounted on a combine, and more particularly, to a threshing apparatus having the characteristics of an arc-shaped water net structure in which a barrel is disposed along the lower side.

In threshing apparatus, as a water net arrange | positioned along the lower side of a barrel, the thing of the structure which fixed the crimp net of metal to the metal mesh frame of circular arc shape is common.

However, in the case of threshing the grain stem containing a large amount of water, the upper surface of the water net (the sudden side) has a structure such that the metal crimp net is fixed to the water net as described above, that is, the arc-shaped metal mesh frame. The water droplets generated on the surface of the mesh are difficult to flow, and as a result of the water droplets adsorbing straw crumbs, the water droplets may cause a reduced shape of the filtration area of the water net, which may cause clogging of the water net.

In recent years, in order to reduce the weight of the water net, improve the discharge performance of the grain and prevent clogging, it has been limited to integrally mold the whole net with a resin such as high molecular weight polyethylene.

However, since the resin mesh is lower in strength than the metal mesh and is inferior to the criminal ground, there is a fear that the mesh will be damaged by the load during the threshing operation.

The present invention has been made in view of the problems described above, and even when supplying grain stems containing a large amount of water, it is possible to suppress the occurrence of clogging of water nets and provide a water net structure of the threshing device with excellent discharge performance. This aims to prevent the warp shape of the resin mesh.

In order to achieve this object, the water net structure of the threshing apparatus according to the present invention is formed by forming an arc-shaped water net disposed along the lower side of the barrel with ultra-high molecular resin, and an arc-shaped rib made of arc-shaped lead metal. The sheet plate is embedded in the inner surface of the above-mentioned water net, and is located on the same surface as the upper surface of the sheet plate and the inner surface of the water net.

Since the water net N is integrally formed with a high wear resistance and a high water-repellent resin, it is not easily abraded, and even if a large amount of water is contained in the grain stem, the water retained in the water net N is small.

Moreover, in a water net, arc-shaped ribs which serve as resistance plates for grain stems fed into the threshing apparatus are arranged along the circumferential direction of the inner surface of the water net.

Therefore, in the case of attaching to the inner surface of the resin made of the arc-shaped ribule metal, the shape retaining function of the water net is made by inserting the arc-shaped sheet plate over the entire length into the recess provided on the inner surface of the water net. Can increase the

Furthermore, since the upper surface of the sheet plate and the inner surface of the water net are located on substantially the same surface, it is difficult to attach straw crumbs around the sheet plate.

Therefore, even when the grain stem containing a large amount of water is supplied by material selection, clogging of the water net does not occur easily, and the existing structure is slightly modified to the arc-shaped ribs and the water net, and both are effective. By using it easily, the deformation of the resin mesh was able to be prevented beforehand.

Moreover, as a suitable embodiment, the following structures can be taken.

(1) The oscillation of the lower guide and the upper guide and the receiving grid that force the set net along the lower guide and the upper guide by vibrating the arc-shaped sidewall of the grid directly from the top and the bottom so that the guide can be slit along the circumferential direction of the barrel. If the water net is made of resin and the water net is made of resin, the water net may rise during vibration driving and may come into contact with the sudden pressure of the water. Vibration is driven at a certain interval.

As a result, the rollers and their supporting structures (support shafts and bearings, etc.) used in the prior art become unnecessary, and the structure can be simplified.

In addition, the contact between the guide and the water net is brought into a slide state by the metal (guide side) and the resin (receive shaft), so that the slide can be smoothly moved without using lubricant or the like.

Therefore, by utilizing the properties of the resin effectively, a smooth and simple structure vibration structure can be obtained, and the production cost can be reduced.

(2) The support plate with ribs is attached to the back of the mesh, and the arc-shaped rib mesh and support plate are fastened and fastened by the fastening member to prevent deformation of the mesh.

(3) Once the upper barrel casing supporting the barrel is pivotally opened and closed with respect to the lower barrel casing, the upper guide is supported on the lower barrel casing, and the non-acting position is opened to the opposite position as the supporting position of the water column. By pivoting around the axial center of the shaft to the lower barrel case, the support net is vibrated by both guide members in the circumferential direction. Even if the threshing treated material starts clogging of a water net, the processed material can be shaken off by vibration, and the clogging according to a short term can be prevented.

In addition, in the case of detaching the water net, the upper guide member can be swinged upward around the lateral chamber, so that the water net can be easily lifted upward, and the upper guide member can only be rocked downward when it is attached again. Sufficient and cumbersome positioning is unnecessary.

Therefore, it is possible to reduce the frequency of maintenance work by preventing clogging in a short period of time in the water net, and furthermore, in maintenance work, the water net can be detached only by rocking operation of the upper guide member. Compared to attaching and detaching the member, it is not troublesome and simple.

Hereinafter, the threshing apparatus which is an embodiment of the present invention will be described based on shaping.

The whole threshing apparatus is comprised as follows.

That is, as shown in FIG. 4, the grain stem conveyed by the feed chain 1 in a fall-falling position by the feed chain 1 is moved by the barrel 3 which is movably installed in the chamber 2 of the threshing apparatus. Threshing between 3) and water net (4).

The threshed rice and the relatively small straw flakes are discharged through the water net 4 arranged below the sliding motion 3, and fall down on the grain pen 6 installed in the lower swing selection frame 5 to prevent the rocking action. It is conveyed while being gravity-selected to the bottom grainsave 7 by this, and the rice is discharged to the 1st water collection part 9 by the rocking action and the blowing effect from the tuyere 8 on the grainsave 7. And recovered.

And the eared rice etc. which were collect | recovered by the 2nd collection | recovery part 10 are returned to the feeding chamber 2 by the conveying screw 25. As shown in FIG.
