Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention is directed to the use of grains with stalks and stalks, which are sent together with straw waste while being sieved by a swinging sorter mounted below the handling room. The present invention relates to a threshing and sorting processing device that attempts to process unprocessed materials such as husks and other unprocessed materials through a rational arrangement of three components: a processing barrel, a suction dust exhaust fan, and a handling chamber.

(b) Prior art A threshing sorting device that processes unprocessed material, which is sent while being sieved by a swinging sorter mounted below the handling chamber, using a processing barrel chamber and a suction dust fan. It is known that the suction dust exhausting fans are provided opposite to each other on both sides above the terminal end of the oscillating sorting body (see, for example, Japanese Patent Publication No. 56-25082).

(c) Problems to be solved by the invention In the conventional method, a processing cylinder is provided in the processing chamber arranged side by side on the side of the processing chamber, the rear end of which protrudes rearward from the processing cylinder in the same direction as the processing cylinder. In addition, dust extraction fans of the same diameter were installed oppositely on both sides of the sorting chamber, which is connected to the rear of the handling and processing chambers, so compared to a system in which dust is removed using a dust extraction fan on one side. Although the dust removal efficiency has been improved, the suction and dust removal action of the dust removal fan is difficult to reach the unprocessed materials that are in the processing chamber and are being processed by the processing cylinder. However, there was a problem in that it was not possible to prevent the migration of branches, branches, etc. within the processing chamber, and their migration reduced processing capacity.

In addition, while the dust in the sorting chamber tends to be unevenly distributed on one side in the left and right direction due to the rotation of the handling cylinder, the two dust exhaust fans installed facing each other on both the left and right sides of the sorting chamber have the same diameter. Since the suction air volume was configured to be the same on both sides, on the side where a large amount of dust was unevenly distributed, grains mixed with it were likely to be discharged outside the machine by the suction force of the dust removal fan. Since the suction forces of the same size of the dust exhaust fans work in opposite directions so as to pull each other, turbulence occurs in the air flow inside the sorting chamber, and the dust exhausting effect is particularly poor in the central part of the sorting chamber. There were some problems that I didn't have.

The present invention has focused on the above-mentioned problems, and has been carried out for the purpose of providing a threshing sorting device that can eliminate these problems.

(d) Means for Solving the Problems That is, the threshing sorting device of the present invention has a structure in which grains are sieved by the swinging sorter a on the terminal side of the swinging sorter a mounted below the handling chamber 1. A processing barrel chamber 3 for receiving and processing the unprocessed materials sent to the center is installed horizontally perpendicular to the swinging direction of the swinging sorter a, and on both sides between the processing barrel chamber 3 and the handling chamber 1. Two suction dust exhaustion fans 17 and 18 with different suction air volumes are provided facing each other, so that the suction dust exhaustion fan 18 located on the side of the swing sorting body a where a large amount of unprocessed material is unevenly distributed is placed on the other side. This fan is characterized by being provided with a suction air volume smaller than that of the suction dust exhaust fan 17 shown in FIG.

(E) Effect In the threshing sorting equipment configured as described above, the material to be handled from the handling room is sieved by the swinging sorter, and after the grains, etc. that have become single grains are sorted out. Unprocessed materials, such as ear cuts and grains with stems, are received into the processing barrel from the end of the oscillating sorter along with straw waste, and are rotated from bottom to top by the rotating processing copper. The processed material leaks out of the processing copper chamber and is sorted, and the dust that does not leak out, such as straw and relatively large branches, is collected by the suction dust exhaust fans on both sides as it rotates from bottom to top. It is then sucked out.

In addition, the suction dust exhaust fan simultaneously sucks and discharges dust such as small pieces of straw floating on the oscillating sorting body using the sorting wind that blows the oscillating sorting body upward and the sieving action.

(F) Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The threshing and sorting processing device shown in this example figure is for mounting on a combine harvester, and the left side in each figure is the front side in the direction of movement, and it takes over the harvested grain culm, threshes it, and sorts it.

This threshing and sorting processing device will be explained with reference to Figs. 1 and 2. Reference numeral 1 denotes a handling chamber, and a handling cylinder 2 built in this chamber rotates in the direction of arrow A, which is a so-called lower handling type. There is.

Reference numeral a denotes a swinging sorting body, and the swinging sorting body a has a feed pan 4, a chaff sheave 5, and a stroke rack 6 installed in sequence from the front start end to the rear end end, and a grain sheave 7 is provided below the chaf sheave 5. A sorting fin 8 is installed from the bottom to the end of the stroke rack 6, and these fins are configured to swing together, swinging back and forth below the handling room 1, and handling and unloading from the handling room 1. It is designed to receive and separate the leaked materials from the treatment room 3 for post-operative treatment. Note that 9 is a pressure fan installed below the starting end side of the oscillating sorting body a.

The processing barrel chamber 3 is located on the terminal end side of the swinging sorting body a, that is, above the sorting fins 8, and is perpendicular to the back and forth swinging direction of the swinging sorting body a, and collects straw waste and unprocessed materials from the terminal bundle of the stroke rack 6 over its entire width. It has a built-in processing cylinder 10 which is installed horizontally so as to be received across the body and which rotates in the direction of arrow B.

An arc-shaped concave 1 is provided in the lower part of the processing barrel chamber 3.
1 is constructed, and the front and rear parts are supported by a guide plate 12 and a support plate 13 installed horizontally on both sides. In addition, the processing barrel chamber 3
The upper part is formed by a cover plate 14, and the upper end of the cover plate 14 is connected to a bottom plate 16 constituting a passage 15 for the straw culm to be conveyed rearward from the culm outlet of the handling chamber 1.

Reference numerals 17 and 18 are suction and dust removal fans, both of which suck dust to the upper side of the stroke rack 6 that constitutes the terminal end of the rocking barrel sorting body a on the front side of the processing barrel chamber 3 between the processing chamber 1 and the processing barrel chamber 3. They are attached to both side walls 19 and 20, respectively, so that the openings 17a and 18a are open to face each other.

The two suction dust exhaust fans 17 and 18 are
The suction cylinders are different in size, and the suction air volume of the suction dust exhaust fan 17 located on the left side, that is, on the feed chain side, is configured to be larger than that of the suction dust exhaust fan 18 on the right side. Further, 21 and 22 are dust exhaust pipes of the suction dust exhaust fans 17 and 18.

The suction ports 17a and 18a are set such that the right suction port 18a is located higher than the left suction port 17a in relation to the stroller rack 6. Further, 23 is a first material take-out gutter, 24 is a second material gutter, 25 is a thrower, and 26 is a reprocessing chamber arranged in parallel with the handling chamber 1.

Therefore, the materials to be handled from the handling room 1 are sorted by the back-and-forth swinging of the swinging sorter a and the sorting air of the pressure fan 9, and are free from small pieces of straw etc. blown up by the sorting air. Dust is removed by suction dust exhaust fan 1 on both sides.
7 and 18, and unprocessed materials such as large straw waste, ear cuts, and grains with stalks are passed from the terminal end of the stroke rack 6 onto the guide plate 12 to the processing barrel chamber 3.
The processing cylinder 10 is received in the processing cylinder 10 and rotates in the direction B, and the processing cylinder 10 rotates from the bottom to the top and is discharged forward to be processed.

The dust that is generated by this processing action and tries to circulate inside the processing barrel chamber 3 is removed by the suction dust exhaust fan 17 as shown by arrows C and D in FIG.
The leakage from the concave 11 which is suctioned and discharged by the concave 11 is received by the sorting fins 8, and by its rocking, broken culms and grains with stalks are separated and discharged backward from the terminal end.

The grains in the first pick-up gutter 23 are stored in the grain storage section, and the grains flowing into the second pick-up gutter 24 are lifted to the reprocessing chamber 26 by the thrower 25 and further processed. It is.

Note that the materials to be handled from the handling room 1 are sorted as described above, but since the handling cylinder 2 is rotating in the direction of A, the materials to be handled are sorted on the right side of the swinging sorter a. The layer is unevenly distributed on the left side, and the layer is thicker than the left side, and the layer is sent to the terminal side while being subjected to the sieving effect due to rocking while maintaining the difference in thickness. Therefore, the sieving action continues to the terminal end on the right side, but the suction air volume of the right side suction and dust removal fan 18 is smaller than that of the left side suction and dust removal fan 17, and the suction port Since 18a is opened at a high position, grains are not easily absorbed and are not discharged outside the machine.

(G) Effects of the Invention As described in detail above, the present invention provides a method for distributing a material that is sent to the terminal end side of the oscillating sorting body a mounted below the handling chamber 1 while being sieved by the oscillating sorting body a. A processing barrel chamber 3 for receiving and processing unprocessed materials is horizontally installed perpendicular to the swinging direction of the swinging sorter a, and suction air volumes are different on both sides between the processing barrel chamber 3 and the handling chamber 1. When the two suction and dust removal fans 17 and 18 are provided facing each other, the suction and dust removal fan 18 located on the side where a large amount of unprocessed materials of the oscillating sorting body a is unevenly distributed is replaced with the suction and dust removal fan 18 located on the other side. Since it is provided with a suction air volume smaller than that of the fan 17, the following effects can be expected.

The material to be handled from the handling room 1 is sorted by the back-and-forth rocking of the oscillating sorter a and the sorting wind, while being subjected to the suction and discharge action of the two suction and dust removal fans 17 and 18. On the moving sorter a, a suction dust exhaust fan 17 with a large suction air volume is located on the opposite side to the side where a large amount of unprocessed materials are unevenly distributed, so that the unused materials unevenly distributed on one side of the oscillating sorter a have a large amount of suction air. The dust is spread out and diluted by the large suction dust exhaust fan 17, and leakage from the oscillating sorting body a is assisted and the sorting performance is improved.

In addition, relatively large straw waste that has reached the terminal end of the oscillating sorter a, and unprocessed materials such as broken ears and grains with stems are thrown into the processing barrel chamber 3 and used for processing in the processing barrel 10. The suction and discharge actions of the two suction and dust removal fans 17 and 18 act simultaneously on the processing process;
18 are provided with different suction air volumes as described above, the majority of the wind in the processing chamber stably flows toward the suction dust exhaust fan 17 with the suction air volume, causing dust to flow turbulently in the center of the processing chamber. In addition, the suction force of the suction dust exhaust fan 17 with a small suction air volume acts auxiliarily on the unevenly distributed grains on the oscillating sorter a, and the grains are removed from the machine. Since only the dust is suctioned and discharged without being taken out, the processing capacity within the processing barrel is significantly improved.
