Description

[Detailed Description of the Invention] (a) Field of Industrial Use The present invention mounts a swing sorting body below a handling chamber, and from the lower side of the starting end side of this swing sorting body to the end side. The present invention relates to a chaff sheave in an oscillating sorting body of a threshing sorting machine that forms a sorting air passage toward which sorting is performed from the handling room by the oscillating action of the oscillating sorting body and the wind blowing through the sorting air passage. .

(B) Conventional technology Conventionally, the swing sorting body is mounted below the handling chamber as described above,
A sorting air passage is formed from the lower side of the start end side of the mounted swinging sorting body toward the terminal end side of the swinging sorting body to swing the goods to be handled from the handling chamber. A threshing sorter for sorting by means of, for example, is publicly known by, for example, JP-A-59-175820.

However, in this conventional threshing and sorting machine, since the second product after threshing and sorting is returned to the feed pan constituting the foremost end side of the rocking sorting body, a large amount of water leaks from the starting end side of the handling chamber. It becomes mixed with the handled goods, which causes deterioration of the sorting performance.

(C) Problem to be solved by the invention As described above, in the conventional threshing sorting machine, the second product after threshing sorting is returned to the feed pan constituting the start end side of the swing sorting body, which is why However, since it is mixed with a large amount of waste that leaks from the starting end of the handling room and causes deterioration of sorting performance, the present invention uses a feed pan to overcome this conventional problem. The 2nd object is dropped and reduced on the connected chaff sheave, and at that time, the culm, branch and the like in the 2nd object pass through between the fins of the chaf sheave and fall into the 1st object. It was devised for the purpose of providing a threshing sorter that has excellent sorting performance and accuracy.

(D) Means for Solving the Problem Therefore, in order to provide the threshing sorter described in the preceding paragraph, the present invention provides a throttling sorter mounted below the handling chamber from the lower side of the starting end side to the end side. A threshing sorter that forms a sorting wind passage toward the side and sorts the handled goods from the handling chamber by the swing sorting body and the wind blowing through the sorting wind passage, the chaff sieve forming the swing sorting body. The second product after threshing selection is reduced and re-sorted, and the inclination angle of several fins at the place where the second product falls and is reduced is smaller than the inclination angle of other fins.
The depth of the concave portion formed by bending the lower end portion of the fin upward is made larger than the depth of the other portions.

(E) Action With this configuration, a large amount of waste from the handling room falls to the start end side of the rocking sorting body and is received and sifted. Unprocessed materials such as etc. are sent to the terminal side together with the straw dust, and are sorted by the wind that blows through the sorting air passage, and are sorted into 1st and 2nd ones and dust such as straws. The No. 1 item is taken out of the machine and the No. 2 item is dropped and returned on the chaff sheaves for re-sorting.

And in this case, the 2nd thing returned to the chaff sheave falls on several fins tilted to a state where the tilt angle is small, and the culm / branch in the 2nd thing is received by the fins, At the lower end where the depth is large, it is prevented from falling between the fins, and the rocking action causes the dust to be sent to the end side together with the straw waste, so that it does not mix into the first product.

(F) Example A threshing sorter according to the present invention will be described below with reference to an example diagram. The threshing sorter (A) shown in this example is for mounting a combine, and the left side of FIG. 1 is the front side with respect to the traveling direction, and since the harvested grain culm is inherited and threshing is performed, sorting is performed. As shown in FIG. 3, the threshing sorter (A) according to the present invention is mounted on the left side of the running part (B) equipped with the crawler, and the right side is the pilot seat (C) from the front part to the rear part.・ Grain tank, paddy receiving part, engine, etc. are arranged in order, and a weeding board in front of the threshing sorter (A) and cockpit (C)
A reaper (D) including a raising case, a cutting blade, a grain culm transport belt, and the like is provided.

(1) is a handling room with a built-in handling barrel (6), and (a) is mounted below the handling room (1) and swings back and forth to pick up unhandled items from the handling room (1) With a swinging sorting body, the feed pan (7) and the chaff sheave (3) from the start end side to the end side.
And the sieve line (8) are sequentially installed, the diffusion receiving plate (9) and the straw rack (10) are connected to the upper side of the chaff sheave (3) from the middle part to the terminal side, and the lower side of the glen sieve (8) is connected. 11) is arranged, and a grain plate (12) is obliquely provided below the Glensieeve (11) so that they can swing integrally.

(13) (13) is a support for suspending the swing selecting body (a), and (14) is a compressed air fan installed below the feed pan (7).

In addition, the wind that blows out from the compressed air fan (14) toward the end side of the rocking sorting body (a) forms a sorting air passage (2), and below this sorting air passage (2). The first pick-up gutter (15) and the second horizontal traverse gutter (16) are horizontally installed from the side of the compressed air fan (14).

Next, the chaff sheave (3) is a large number of fins (4).
Of the fins (4) are bent side by side in a rearwardly tilted posture with a space between them in the front-rear direction, and the lower ends of the fins (4) are bent upward to form recesses (5). The inclination can be changed and adjusted.

The diffusion receiving plate (9) is located below the dust inlet (17) of the handling chamber (1) while the front side is inclined downward to the front and the rear side is substantially horizontal, and the fried cylinder (18) is used. The terminal end of the second horizontal traverse gutter (16) communicates with the upper side of the diffusion receiving plate (9).

In addition, among the fins (4), some fins (4) in an inclined posture corresponding to the lower side of the front end portion (9a) of the diffusion receiving plate (9) have different inclination angles (α) from other fins (4). The depth (H) of the concave portion (5) formed at the lower end is made larger than the depth (h) of the other concave portion (5) by making it smaller than the inclination angle (β) of (4). To make it deeper.

With such a configuration, the goods to be handled from the handling room (1) swing back and forth around the swing sorting body (a) and the compressed air fan (14).
The air generated by the air is sorted in the sorting air passage (2), and a large amount of it is placed on the feed pan (7) located on the starting end side of the swing sorting body (a) from the handling chamber (1). As shown by the arrow (a), the unhandled goods that fall into the area are received and sifted by the chaff sheave (3), and the unhandled goods from the middle of the handling room (1) are as shown in (b). It directly drops onto the chaff sieve (3) and is screened. In addition, a culm or a branch vein easily leaks from the terminal end of the handling room (1), which itself is received by the front side of the diffusion receiving plate (9) as shown in (c) and its front end (9a). Those which are dropped from the screen and are sieved and discharged from the dust inlet (17) as shown in (d) are transferred to the Straw rack (10) from the rear side of the diffusion receiving plate (9) and swing-sorted. Of.

Then, untreated materials such as cuttings and grains with branching in the unsorted materials that are sieve-sorted with the chaff sieve (3) are blown through the sorting air passage (2) while being sent toward the terminal end side with the straw waste. It is wind-selected by the 1st and 2nd ones and the dust such as straw, the 1st one is taken out of the machine by the 1st takeout gutter (15), and the 2nd one is taken out. After being laterally fed by the second horizontal traverse gutter (16), it is lifted up by the fried grain cylinder (18) and received by the front side of the diffusion receiving plate (9) as shown by the arrow (e), while spreading in the lateral width direction. From the front end (9a) to the chaff sheave (3), the particles are reduced and re-sorted.

In this case, the material leaking from the end of the handling chamber (1) and the material lifted by the fried food container (18) fall from the front end (9a) of the diffusion receiving plate (9). Then, several fins (4) of the chaff sheave (3) at the place where the falling object is received tilts to a smaller state at an inclination angle (α) and receives the culm / branch in it while the depth ( At the large lower end of (H), the fins (4) are prevented from falling without being dropped, and by the swinging action, they are sent to the terminal side together with the straw waste as shown in (F).

(G) Effect of the Invention As described in detail above, the present invention forms a sorting air duct from the lower side of the starting end side to the terminal side of the swing sorting body mounted below the handling room to form the sorting air passage from the handling room. A threshing / sorting machine for sorting unhandled foods by an oscillating sorting body and a wind blowing through a sorting air duct, wherein the threshing / sorting is performed on a chaff sheave constituting the oscillating sorting body after threshing sorting 2
The number of the fins is reduced and re-sorted, and the angle of inclination of some fins where the second number falls and is reduced is smaller than the angle of inclination of other fins, and the lower end of the fins is bent upward. Since the depth of the concave portion formed by making it larger than the depth of other ones, the second item after threshing and sorting will be dropped and reduced on the chaff sheaves and will be re-sorted. As described above, since the second product is not returned to the feed pan that constitutes the starting end side of the swing selecting body, the second product is prevented from being mixed with a large amount of unprocessed products from the starting end side of the handling chamber, thereby deteriorating the sorting performance. There is no.

In addition, the inclination angle of several fins where the second object is dropped and reduced is smaller than the inclination angle of the other fins, and the depth of the recess formed by bending the lower end of the fin upward is different. Since the fins are deeper than the depth of the ones, the culm and branch in the second one are received by the fins, but at the lower end with a large depth, it is prevented from falling between the fins and the rocking action causes the straw to fall. Since it comes to be sent to the end side together with the waste and is not mixed in the first product, there is an effect that the sorting accuracy is also excellent.
