Utility Model Publication No. 61-75883

However, the conventional dust evacuation device has a problem in that it requires a certain amount of installation space because it is installed on the conveyance line. In addition, there were other problems such as the need for chute piping work in order to connect the dust removal device, the height of the elevator, and the depth of the pit. Furthermore, in the prior art (for example, Patent Document 1, etc.), there was a problem that the dust removal device itself became large. That is, in the prior art, there was a problem in that the device itself or its peripheral components became large due to the structure and installation method of the dust removal device.

SUMMARY OF THE INVENTION The present invention has been devised to solve the problems of the prior art described above, and is an air vent system that has a relatively compact structure and is capable of effectively removing foreign matter and debris such as straw, dirt, and dust. An object of the present invention is to provide a dust removal device equipped with a selection mechanism.

The dust removal device according to the first aspect of the present invention includes a grain input section for inputting transported grain, a grain discharge section for discharging the inputted grain, and a suction and discharge of dust mixed in the grain. The grain discharge section is provided in a direction in which the input grain falls, and the garbage discharge section is provided at a position facing the grain discharge section, and the grain discharge section and the grain discharge section are provided in a direction opposite to the grain discharge section. A partition plate is provided between the dust discharge section and the grain discharging path (grain discharging path) communicating with the grain discharging section. It is configured to be rotatable by collision of the grains in order to vary the dust discharge path (discharge path area) and the dust discharge path (dust discharge path area) communicating with the dust discharge section.
In the dust removal device according to the present invention, the grains falling from the grain input section to the grain discharge section collide with the partition plate, so that the grain discharge path becomes large and the dust discharge path becomes small. The partition plate rotates so that.

According to the dust evacuation device configured in this way, the grains that have fallen from the grain input section and have not yet been discharged from the grain discharge section collide with the partition plate, thereby causing the partition plate to rotate; The grain discharge route and the dust discharge route will vary. More specifically, when the grains collide with the partition plate, the partition plate rotates so that the grain discharge path becomes larger (widens) and the garbage discharge path becomes smaller (narrows). do.
Therefore, according to the dust evacuation device according to the present invention, as the amount of grain conveyed increases, the grain ejection path becomes larger and the waste ejection path becomes smaller, so that the suction speed in the waste ejection section increases. I will do it. In other words, according to the present invention, the suction speed at the garbage discharge section changes depending on the amount of grain conveyed, and as the amount of grain conveyed increases, the suction speed at the garbage discharge section increases. Therefore, it is possible to obtain a dust evacuation device that can effectively discharge the dust that is transported and thrown in along with the grains.

Further, the dust removal device according to the second aspect of the present invention includes a grain input section for inputting the transported grains, a grain discharge section for discharging the inputted grains, and a suction unit for sucking dust mixed in the grains. The grain discharging section is provided at a position below the grain inputting section, the garbage discharging section is provided at a position above the grain inputting section, and the grain discharging section and the garbage discharging section are provided at a position above the grain inputting section. A partition plate is provided between the grain discharge section and the grain discharge section at a position where it collides with the grains thrown in from the grain input section. It is configured to be rotatable by collision of the grains in order to change the dust discharge path (path area) and the dust discharge path (dust discharge path area) communicating with the dust discharge section.
In the dust removal device according to the present invention, the grains collide with the partition plate before being discharged from the grain discharge section provided below the grain input section, so that the grain discharge path is widened. The partition plate is rotated so that the dust discharge path becomes smaller.

According to the dust evacuation device configured in this way, the grains collide with the partition plate before being discharged from the grain discharge section provided below the grain input section, so that the partition plate is removed. As a result, the grain discharge path and the dust discharge path change. More specifically, when the grains collide with the partition plate, the partition plate rotates so that the grain discharge path becomes larger and the garbage discharge path becomes smaller.
Therefore, according to the dust evacuation device according to the present invention, as the amount of grain conveyed increases, the grain ejection path becomes larger and the waste ejection path becomes smaller, so that the suction speed in the waste ejection section increases. I will do it. In other words, according to the present invention, the suction speed at the garbage discharge section changes depending on the amount of grain conveyed, and as the amount of grain conveyed increases, the suction speed at the garbage discharge section increases. Therefore, it is possible to obtain a dust evacuation device that can effectively discharge the dust that is transported and thrown in along with the grains.

Furthermore, in the dust removal device according to a third aspect of the present invention, in the configuration of the first aspect or the second aspect, the upper part of the partition plate closes the grain input section and the garbage discharge section. It is preferable that
According to this preferred configuration, since the upper part of the partition plate is configured to close the grain input part and the garbage discharge part, each of the grain discharge path and the garbage discharge path in the lower part of the partition plate is closed. The suction speed in the dust discharge section is determined according to the area of the dust discharge section. In other words, as the number of grains colliding with the partition plate increases, the area of the dirt discharge path becomes smaller due to the rotating partition plate, so that the suction speed in the dirt discharge section increases. Therefore, according to this preferable configuration, the dust mixed in the grain can be effectively discharged.

According to the present invention, it is possible to obtain a dust evacuation device equipped with a wind selection mechanism that can effectively remove foreign substances such as straw, dirt, and dust with a relatively compact configuration.

Since the suction air A is sucked across the downward flow of the grain K shown in the grain discharge path 220 (see FIG. 4), in this embodiment, the straw waste mixed in the grain K, Foreign matter such as dirt and dust can be effectively removed. In this embodiment, as the suction air A moves, the dust mixed in the grains K is appropriately discharged from the dust discharge section 203 to the outside of the second dust removal device 200.

Since the second dust removal device 200 according to the present embodiment is configured as described above, it has the following effects. Hereinafter, based on the above-described configuration, the effects, etc. of the second dust removal device 200 according to the present embodiment will be explained using FIGS. 1 and 4.

FIG. 4 is a schematic diagram of the second dust evacuation device 200 according to the embodiment of the present invention, showing a rotating state of the partition plate 210 forming the second dust evacuation device 200. More specifically, FIG. 4(a) is a schematic diagram showing a state in which the partition plate 210 is not rotated before the grains K are input into the second dust evacuation device 200. b) is a schematic diagram illustrating a state in which grains K are charged into the second dust evacuation device 200, collide with the partition plate 210, and the partition plate 210 is rotating.

The second dust removal device 200 according to the present embodiment is provided above the elevator 400, and the grain K transported by the bucket 403 of the elevator 400 is removed from the grain input section 201 as the bucket 403 moves. It is configured to be inserted into the second dust removal device 200.

Grain K input into the grain input unit 201 from the elevator 400 (the bucket 403 forming the elevator 400) collides with a partition plate 210 provided in the second dust evacuation device 200. More specifically, the grains K collide with the lower part 210b of the partition plate 210. The lower part 210b of the partition plate 210 is bent toward the elevator 400, so that the grain K fed from the grain input section 201 is reliably fed to the lower part 210b of the partition plate 210 (the lower part 210b of the partition plate 210). This will cause a collision.

When the grains K collide with the lower part 210b of the partition plate 210, the collision energy makes it easier to separate the grains K from the dust mixed in the grains K. That is, when the grains K collide with the partition plate 210, the dust mixed in the grains K is effectively separated from the grains K before and after the partition plate 210 in the second dust removal device 200.

Furthermore, when the grains K collide with the lower part 210b of the partition plate 210, the partition plate 210 constituting the second dust evacuation device 200 according to the present embodiment moves around the partition plate mounting shaft part 215, and the elevator 400 Rotate in the direction away from. As the partition plate 210 rotates in the direction away from the elevator 400, the grain discharge path (grain discharge path area) 220 widens, and the garbage discharge path (dust discharge path area) 230 will be narrowed. Further, even if the grain K collides with the partition plate 210 and the partition plate 210 rotates in a direction away from the elevator 400, the partition plate of the partition plate 210 is arranged so that the partition plate 210 does not come into contact with the inside of the main body casing portion 200A. Since the end of the upper part 210a and the casing of the elevator 400 come into contact and the movement of the partition plate 210 is restricted, the garbage discharge path 230 is not blocked.

In this embodiment, the suction air A flows in the direction of the outlined arrow in FIG. 4(b). That is, the suction air A flows from the elevator 400 side through the dust discharge path 230 toward the dust discharge section 203 and the outside thereof. By this suction air A, in the second dust removal device 200 according to the present embodiment, the dust mixed in the grains K is removed from the dust discharge section 203 to the outside of the second dust removal device 200 via the dust discharge path 230. be discharged.

As described above, when the grains K collide with the partition plate 210, the grain discharge path 220 widens and the garbage discharge path 230 narrows. By widening the grain discharge path 220, the grains K can be efficiently discharged from the grain discharge section 202. In addition, the narrowing of the dust discharge path 230 increases the flow rate (suction speed) of the suction air A in the dust discharge path 230. According to the second dust removal device 200 according to the present embodiment, the more the amount of grain K to be conveyed, the more the dust discharge path 230 becomes narrower and the suction speed in the dust discharger 203 increases. The garbage thrown in can be effectively discharged via the garbage discharge path 230 and the garbage discharge section 203.

Since the first dust removal device 100 and the second dust removal device 200 according to the present embodiment have the configurations described using FIGS. 1 to 4, the following effects are achieved.

The dust removal device (the first dust removal device 100, the second dust removal device 200) according to the present embodiment includes grain input sections 101, 201 into which the transported grain K is input, and grain input sections 101 and 201 into which the input grain K is discharged. The grain discharge parts 102, 202 are provided in the direction in which the input grain K falls, and the dust discharge parts 103, 203 suck and discharge the dust mixed in the grain K. Dust discharge parts 103, 203 are provided at positions facing the grain discharge parts 102, 202, and between the grain discharge parts 102, 202 and the dust discharge parts 103, 203, the grains fed from the grain input parts 101, 201 are disposed. Partition plates 110, 210 are provided at positions where they collide with the grains K, and the partition plates 110, 210 are connected to grain discharge paths (grain discharge path area) 120, 220 communicating with the grain discharge sections 102, 202 and to garbage. It is configured to be rotatable by the collision of grains K in order to change the dust discharge paths (dust discharge path area) 130, 230 communicating with the discharge parts 103, 203. In the dust evacuation device (first dust evacuation device 100, second dust evacuation device 200) according to the present embodiment, the grain K falling from the grain input portions 101, 201 to the grain ejection portions 102, 202 is removed from the partition plate 110. , 210, the partition plates 110, 210 rotate so that the grain discharge paths 120, 220 become larger and the dust discharge paths 130, 230 become smaller.

According to the dust removal device 100, 200 configured in this way, the grain K that falls from the grain input section 101, 201 and before being discharged from the grain discharge section 102, 202 collides with the partition plate 110, 210. As a result, the partition plates 110, 210 rotate, and the grain discharge paths 120, 220 and the garbage discharge paths 130, 230 change. More specifically, when the grain K collides with the partition plates 110, 210, the grain discharge paths 120, 220 become larger (widening), and the dust discharge paths 130, 230 become smaller (narrowed). The partition plates 110 and 210 rotate.
Therefore, according to the dust evacuation devices 100, 200 according to the present embodiment, as the conveyance amount of grain K increases, the grain ejection paths 120, 220 become larger and the dust ejection paths 130, 230 become smaller. The suction speed in the discharge paths 130, 230 will increase. In other words, according to the present embodiment, the suction speed in the dust discharge paths 130, 230 changes depending on the conveyance amount of the grain K, and the more the conveyance amount of the grain K increases, the more the suction speed in the dust discharge paths 130, 230 increases. Since the speed increases, it is possible to obtain dust removal devices 100 and 200 that can effectively discharge the dust that is transported and thrown in along with the grains K.

Further, the dust removal device 100, 200 according to the present embodiment includes a grain input section 101, 201 that inputs the transported grain K, a grain discharge section 102, 202 that discharges the input grain K, and a grain discharge section 102, 202 that discharges the input grain K. The grain discharge sections 102, 202 are provided below the grain input sections 101, 201, and the garbage discharge sections 102, 202 are provided above the grain input sections 101, 202. Discharging sections 103, 203 are provided, and between the grain discharging sections 102, 202 and the garbage discharging sections 103, 203, a partition plate is provided at a position where it collides with the grain K input from the grain input sections 101, 201. 110, 210 are provided, and the partition plates 110, 210 are provided with grain discharge paths (grain discharge path area) 120, 220 communicating with the grain discharge sections 102, 202 and garbage discharge paths communicating with the garbage discharge sections 103, 203. In order to vary the (dust discharge path area) 130, 230, it is configured to be rotatable by the collision of grains K. In the dust removal device 100, 200 according to the present embodiment, the grain K collides with the partition plate 110, 210 before being discharged from the grain discharge section 102, 202 provided below the grain input section 101, 201. By doing so, the partition plates 110, 210 are rotated so that the grain discharge paths 120, 220 become larger and the dust discharge paths 130, 230 become smaller.

According to the dust removal device 100, 200 configured in this way, the grain K before being discharged from the grain discharge section 102, 202 provided at the lower position of the grain input section 101, 201 is removed from the partition plate 110, 210. The partition plates 110, 210 rotate due to the collision, and the grain discharge paths 120, 220 and the garbage discharge paths 130, 230 change. More specifically, when the grain K collides with the partition plates 110, 210, the partition plates 110, 210 are rotated so that the grain discharge paths 120, 220 become larger and the dust discharge paths 130, 230 become smaller. do.
Therefore, according to the dust removal devices 100, 200 according to the present embodiment, as the amount of grain K to be conveyed increases, the grain discharge paths 120, 220 become larger and the dust removal paths 130, 230 become smaller, so that the dust removal The suction speed in the discharge paths 130, 230 will increase. In other words, according to the present embodiment, the suction speed in the dust discharge paths 130, 230 changes depending on the amount of grain K transported, and the more the amount of grain K transported increases, the more the suction speed in the dust discharge paths 130, 230 increases. Since the speed increases, it is possible to obtain dust removal devices 100, 200 that can effectively discharge the dust that is transported and thrown in along with the grains K.

Furthermore, it is preferable that the dust removal devices 100, 200 of this embodiment have a configuration in which the upper part of the partition plate 110, 210 closes off the grain input section 101, 201 and the dust discharge section 103, 203.
According to this preferred configuration, since the upper part of the partition plates 110, 210 is configured to close the grain input parts 101, 201 and the garbage discharge parts 103, 203, the grain discharge path in the lower part of the partition plates 110, 210 The suction speed in the dust discharge paths 120, 220 is determined according to the respective areas of the dust discharge paths 120, 220 and the dust discharge paths 130, 230. In other words, as the number of grains K colliding with the partition plates 110, 210 increases, the area of the dust discharge paths 130, 230 becomes smaller due to the rotating partition plates 110, 210, and therefore the suction speed in the dust discharge paths 130, 230 increases. do. Therefore, according to this preferred configuration, the dust mixed in the grains K can be effectively discharged.
