One embodiment of the present invention will be described with reference to the drawings. 1 is a crusher that suppresses the flow of grains K (transferred material) being conveyed through a conveyance channel and prevents crushing or cracking of grains K that occurs during conveyance. This is a flow suppressing device for prevention, and is installed at any point in the middle of the piping 2 that constitutes the conveyance flow path.
Although the arrangement and configuration of the conveyance channel and the piping 2 are arbitrary, as an example, FIG. A horizontal conveyor 6 is provided at the top of the tank 4 to distribute and convey the grain K lifted by the elevator 5 to each rice storage tank 4, and a horizontal conveyor 6 is provided at the bottom of each rice storage tank 4. , a transverse conveyor 6 is provided to convey the grains K discharged from each rice delivery tank 4, and the end of the transverse conveyor 6 is connected to a supply section (supply hopper) of a separately provided elevator 5. The upper part of the pipe 2 is connected to the outlet 7, the lower part of the pipe 2 is connected to the upper part of a sub-tank 8, and the sub-tank 8 is connected to the upper part of a measuring device measuring device 10 via a feeding device 9. A starting end of a separate conveyance device 12 is connected to a discharge port (discharge portion) 11 of the weighing device 10 .

A flow suppressing device 1 for preventing crushing is provided near the bottom of the pipe 2 that connects the elevator 5 and the sub-tank 8.
In the flow suppression device 1 for preventing crushing, the lower part of the upper pipe 2 in the transport direction is connected to the upper part of the case 15, and the upper part of the lower pipe 2 in the transport direction is connected to the lower part of the case 15 (FIGS. 1 and 2). .
A restraining partition plate 17 is provided below the inlet 16 in the upper part of the case 15. The suppression partition plate 17 has the function of partitioning a storage space T in which grains K are stored on the suppression partition plate 17, which will be described later, and an overflow space S through which the grains K overflowing from the storage space T spill and pass. It has the effect of suppressing the conveyance of grains K flowing down from the inlet 16 of the case 15.

The suppressing partition plate 17 is formed into a flat plate shape and is provided below the inlet 16 so as to protrude in a direction perpendicular to the falling direction of the grains K when viewed from the front.
Therefore, the grains K falling from the inlet 16 fall onto the group of grains K stored on the upper surface of the suppression partition plate 17, and the impact is alleviated and the flow is suppressed.
A mounting portion 18 is provided on the lower surface (back surface) approximately midway between the upper and lower sides of the suppression partition plate 17, and the mounting portion 18 is fixedly attached to a mounting shaft 19 in the front-rear direction with a bolt 20 (FIG. 8).
When installing the restraining partition plate 17, when the restraining partition plate 17 is placed in a horizontal state, the mounting holes between the mounting portion 18 and the mounting shaft 19 can be visually recognized, and in this state, the restraining partition plate 17 is fixed with bolts 20 (FIG. 6).

The suppressing partition plate 17 is configured such that its inclination angle can be freely adjusted by an adjusting mechanism 21. The adjustment mechanism 21 has an operating lever 25 attached to the mounting shaft 19, and the operating lever 25 is attached rotatably about the mounting shaft 19 to adjust the inclination angle of the suppression partition plate 17.
The operating lever 25 is provided with an arc-shaped moving groove 26 centered on the mounting shaft 19, and a fixed dial 27 is attached to the moving groove 26 to fix the inclination angle of the angle-adjusted suppression partition plate 17 (FIG. 2).

Therefore, when the adjustment mechanism 21 loosens the fixed dial 27 and rotates the operating lever 25 around the mounting shaft 19 using the knob 28 of the operating lever 25, the inclination angle of the suppression partition plate 17 is changed, and the grain K is rotated. After adjusting the degree of flow suppression, the fixed dial 27 is tightened to fix the rotation of the operating lever 25 and the suppression partition plate 17.
In this case, the lower end of the suppression partition plate 17 is rotated counterclockwise around the mounting shaft 19 in FIG.

On the other hand, the upper end of the suppression partition plate 17 always forms the overflow space S with the right side plate 35 of the case 15, and when a certain amount of grain K accumulates on the upper surface (surface) of the suppression partition plate 17, It is configured such that the overflowing grains K pass through the overflow space S and move below the case 15.
Therefore, the grains K flowing down into the case 15 from the inlet 16 of the case 15 accumulate on the suppression partition plate 17, and subsequent grains K fall onto the accumulated grains K, absorbing the impact. The generation of damage such as cracking of grains K is suppressed, and when the amount of grains K accumulated on the suppression partition plate 17 exceeds a predetermined amount, the grains K are overflowed into the overflow space S, and the suppression partition plate 17 This prevents the occurrence of clogging caused by grain K, thereby suppressing the flow of grain K while preventing clogging of grain K.

Therefore, the amount of grain K flowing into the upper pipe 2 of the flow suppression device 1 for preventing crushing is the same as the amount of grain K flowing out from the lower pipe 2 of the case 15 below the suppression partition plate 17. Although the conveyance amount of grains K is not changed, grains K can be accumulated by the suppressing partition plate 17 to suppress the flow of grains K, and damage such as cracking of grains K during conveyance can be suppressed.
In this case, the lateral width X of the case 15 at the portion where the suppression partition plate 17 is provided is formed larger than the lateral width Y of the case 15 below the lower end of the suppression partition plate 17 to ensure an overflow space S. (Figure 1).

Further, an opening 37 is provided in the left side plate 31 of the case 15 in the portion where the suppression partition plate 17 is provided, and the opening 37 is closed by the inspection lid 30 while the grains K are being transported.

When placed in the horizontal state (FIG. 6), the attachment portion between the mounting portion 18 of the suppression partition plate 17 and the mounting shaft 19 can be seen, and the suppression partition plate 17 can be attached or detached by attaching or removing the bolts 20. Maintenance such as cleaning of the partition plate 17 and the inside of the case 15 can be performed.

In addition, a transparent inspection window (see-through window) 39 is provided above the mounting shaft 19 of the front plate 38 of the case 15 (Fig. 5), and the storage amount of grains K on the suppression partition plate 17 and the overflow space S are provided. It is possible to visually recognize the grains K overflowing to the grain K, thereby adjusting the inclination angle of the suppression partition plate 17.
Below the buffer section 40 constituted by the suppression partition plate 17 of the case 15 and the overflow space S, there is a foreign matter removal section 41 that removes foreign matter such as vinyl pieces, strings, bolts, screws, metal powder, etc. from the grain K. (Figures 1 and 2).
The foreign matter removing section 41 includes a substantially horizontal sorting net 42 below the buffer section 40 . The sorting net 42 is placed on a pair of front and rear supports 44 provided on a mounting member 43 that is detachably attached to the case 15 (FIGS. 9 and 10). The entire case 15 is inserted through the lower opening 45 provided in the left side plate 31 (FIGS. 1 and 2).

FIG. 12 shows a configuration in which a flow suppressing device 1 for preventing crushing is provided in a conveying device H that conveys grains K such as rice, wheat, feed, etc. by air. The inside of the pipe 2 is suctioned by the air blower 60, and the grains K are air-transported from the tensioning hopper 61 provided at the starting end of the pipe 2 to the storage tank 63 for storing the grains K. The side piping 2 is provided with a flow suppressing device 1 for preventing crushing.

Therefore, the grains K transported by the suction air by the air blower 60 are transported through the curved pipe 2 by the buffer section 40 of the flow suppressing device 1 for preventing fragmentation, and the transport resistance is relieved by the buffer section 40 of the flow suppressing device 1 for preventing fragmentation. It is possible to prevent the generation of grains and broken rice, and remove the foreign matter in the grains K that are suctioned and dropped while the flow is suppressed by the storage space T and the overflow space S by the foreign matter removal section 41 without damaging the grains K. .

Although the configuration of the conveyance device H is arbitrary, as an example, a grain separation device 64 is provided on the upper side of the storage tank 63 for separating the grains K from the conveyance wind that conveys the grains.
The grain separation device 64 of this embodiment is provided with a powder removal device 65 for removing powder F generated by scraping the surface of grains such as bran or bran.
In this case, the powder removal device 65 is provided in the grain separation device 64, and the grain separation device 64 separates the grain from the conveying air, and removes powder such as bran or bran on the surface of the grain. Remove F.

Attenuates the conveying wind and separates the grain from the conveying wind.
When the grains are separated from the conveying air, the powdery matter F is removed by the powdery matter removal device 65, and the removed powdery matter F is sucked and separated from the grains, thereby producing the separated powdery matter. F conveys the conveying air from the grain separator 64 to the powder separator 66 through the exhaust pipe 2, and the powder F separated by the powder separator 66 is discharged from the exhaust section of the blower 60. The powder is conveyed and collected by pressure air to the powder collection section 67.

On the other hand, the grains from which the powdery substance F has been removed and separated from the air enter the storage tank 63, and are supplied from the storage tank 63 to the next process G, such as color sorting work, weighing, and bagging work.
The powder removal device 65 in the grain separation device 64 forms a suction chamber 70 between the outer periphery of the porous inner cylindrical portion 68 and the outer case 69, and connects the suction chamber 70 with the piping 2 for sucking. There is.
The powder in the grains K inside the porous inner cylinder part 68 of the powder removal device 65 is sucked from the suction chamber 70 in the grain separation device 64, and the sucked powder is air conveyed through the piping 2. The transported powder F is separated by a powder separation device (dust cyclone) 66 that separates it from the transport air, and is transported and collected by a powder recovery section 67 .

(Action of embodiment)
The present invention has the above-described configuration, in which the grains K (materials to be transported) in the plurality of rice storage tanks 4 of the grain storage facility 3 are discharged and transported by the horizontal transport conveyor 6, and the grains K transported by the horizontal transport conveyor 6 are The grains are supplied to the supply section (supply hopper) of the elevator 5, fried, and transported to the sub-tank 8 through the piping 2.

In this case, if the grains (grain K) lifted by the elevator 5 are simply transported to the sub-tank 8 through the pipe 2, the grains K will collide with the metal inner peripheral surface in the sub-tank 8, and the impact of this collision will cause Grain K cracks, resulting in cracked grains and broken rice.
In the present invention, since the flow suppressing device 1 for preventing crushing is provided at the lower part of the pipe 2, the flow suppressing device 1 for preventing crushing reduces the impact of the inflow of grains (grain K), and prevents cracked grains and broken rice. Prevent occurrence.

The flow suppressing device 1 for preventing crushing connects the lower part of the upper pipe 2 in the conveyance direction to the upper part of the case 15, and the suppressing partition plate 17 is provided below the inlet 16 in the upper part of the case 15, so that the inlet The grains K flowing down from the grains K fall on the grains K stored on the suppression partition plate 17, and the impact is absorbed, thereby preventing the generation of cracked grains and broken rice.
The suppression partition plate 17 is formed into a flat plate shape and is provided below the inlet 16 so as to protrude in a direction crossing the falling direction of the grains K when viewed from the front, so that the suppression partition plate 17 receives the grains K.

In the adjustment mechanism 21, when the fixed dial 27 is loosened and the control lever 25 is rotated around the mounting shaft 19 by the knob 28 of the control lever 25, the inclination angle of the suppression partition plate 17 is changed, and the flow of grains K is changed. After adjusting the degree of suppression, it is possible to tighten the fixed dial 27 to fix the rotation of the operating lever 25 and the suppression partition plate 17, thereby changing the inclination angle of the suppression partition plate 17, thereby increasing the grain K. The degree of flow suppression can be adjusted.

In this case, the lower end of the suppression partition plate 17 is rotated counterclockwise in FIG. A gap 33 is formed between the lower end of the suppression partition plate 17 and the case inner surface (left side plate 31) 32 of the case 15, and this gap 33 is configured so that the grains K flow down.

Since the grains K accumulated in a predetermined amount and overflowed beyond this amount move to the lower part of the case 15 through the overflow space S, the flow of the grains K is suppressed while preventing clogging of the grains K.

That is, if the flow is simply suppressed by the suppressing partition plate 17, clogging of grains K will occur within the case 15 of the flow suppressing device 1 for preventing crushing. Since the flow space S is provided, the amount of grains flowing in from the upper side pipe 2 matches the amount of grains flowing out from the lower side pipe 2, and the grain K is stored by the suppressing partition plate 17 to prevent the flow of grains K. can be suppressed, and damage such as cracking of the grains K during transportation can be suppressed.

In another embodiment shown in FIG. 12, the air blower 60 is driven to suck the inside of the pipe 2 and transport the grains K with the suction conveying air, and the grains K are supplied to the tensioning hopper 61. The grains K are air-transported to the storage tank 63.
In this case, since the flow suppressing device 1 for preventing crushing is provided in the pipe 2 on the upper side of the transport tank 63, the grains K transported by the transport air from the blower 60 are transported inside the curved pipe 2. The buffer section 40 of the flow suppressing device 1 for preventing crushing reduces the conveying resistance when the rice is crushed, thereby preventing the occurrence of cracked grains and broken rice. Foreign matter in the grains K falling under suction while the flow is suppressed can be removed without damaging the grains K.

That is, the grains K that have been stocked in the stocking hopper 61 are transported to a higher position than the grain separating device 64 that separates the grains K from the transport air provided at the top of the storage tank 63, and then are transported while falling. Since the grains enter the grain separator 64, if there is a bend or curve in the pipe 2 during the falling process, the conveyance resistance will increase. However, in the present invention, a flow suppression device for preventing crushing is installed in the pipe 2 on the upper side of the grain separator 64. 1, the conveyance resistance is alleviated and generation of cracked grains and broken rice can be prevented.

Although the configuration of the conveyance device H is arbitrary, as an example, a grain separation device 64 is provided on the upper side of the storage tank 63 for separating the grains K from the conveyance wind that conveys the grains.
The grain separation device 64 of this embodiment is provided with a powder removal device 65 for removing powder F generated by scraping the surface of grains such as bran or bran.
In this case, the powder removal device 65 is provided in the grain separation device 64, and the grain separation device 64 separates the grain from the conveying air, and removes powder such as bran or bran on the surface of the grain. Remove F.

The grain separator 64 blows the grains, which have been introduced into the tension hopper 61 and is air-transported to the grain separator 64, into the grain separator 64 together with a conveying air, and causes the grains to fall while rotating. , to attenuate the conveying wind and separate the grains from the conveying wind.
When the grains are separated from the conveying air, the powdery matter F is removed by the powdery matter removal device 65, and the removed powdery matter F is sucked and separated from the grains, thereby producing the separated powdery matter. F conveys the conveying air from the grain separator 64 to the powder separator 66 through the exhaust pipe 2, and the powder F separated by the powder separator 66 is discharged from the exhaust section of the blower 60. The powder is conveyed and collected by pressure air to the powder collection section 67.

On the other hand, the grains from which the powdery substance F has been removed and separated from the air enter the storage tank 63, and are supplied from the storage tank 63 to the next process such as color sorting work, weighing, and bagging work.
The powder removal device 65 in the grain separation device 64 forms a suction chamber 70 between the outer periphery of an inner cylindrical portion 68 formed of a perforated plate having a smaller diameter than the grain K and an outer case 69. The pipe 2 is connected to the piping 2 that sucks the water.

The powder in the grains K inside the porous inner cylinder part 68 of the powder removal device 65 is sucked from the suction chamber 70 in the grain separation device 64, and the sucked powder is air conveyed through the piping 2. The transported powder F is separated by a powder separation device (dust cyclone) 66 that separates it from the transport air, and is transported and collected by a powder recovery section 67 .
