[0001] The utility model relates to the technical field of rice processing, and relates to a multi-stage impurity removal device. Background Art

[0002] Rice processing refers to the process of converting rice into rice with better edible quality through a series of technological processes;

[0003] Rice processing includes removing impurities from rice, and there are multiple stages of removing impurities from rice, including manual selection, wind selection, screening, magnetic separation, etc. The magnetic method specifically uses the magnetic difference between metal impurities and rice to absorb metal impurities in rice through the magnetic force of magnetic steel. This method can effectively remove magnetic impurities such as iron nails and iron sheets mixed in rice.

[0004] In rice planting areas and during mechanical harvesting, there is a possibility of iron filings being worn away by machinery. Therefore, there may be relatively small iron filings in the rice. When the magnet attracts a large amount of rice, the small iron filings may be mixed in the large amount of rice, which may easily cause the iron filings to be unable to effectively appear within the suction range of the magnet, resulting in the small iron filings being unable to be effectively removed;

[0033] Reference Figure 1 and Figure 2 A multi-stage impurity removal device comprises an impurity removal plate 1, and the impurity removal plate 1 is used for rolling down rice. The impurity removing plate 1 is provided with an angle adjustment structure 2, which includes a bottom plate 201 located below the impurity removing plate 1, two groups of springs 202 are installed on the top of the bottom plate 201, a support rod 203 is installed on the top of one group of springs 202, a first rotating rod 205 is installed on the outer side of the impurity removing plate 1, and the first rotating rod 205 is rotatably connected with the support rod 203, a sliding opening 209 is opened through the impurity removing plate 1, a hydraulic rod 206 is installed on the top of another group of springs 202, and a support block 207 is installed at the telescopic end of the hydraulic rod 206, and the impurity removing plate 1 is slidably connected with a second rotating rod 210 through the sliding opening 209, and the second rotating rod 210 is rotatably connected with the support block 207, by starting the hydraulic rod 206, the telescopic end of the hydraulic rod 206 drives the support block 207 to move up or down, and the movement of the support block 207 drives the movement of one end of the impurity removing plate 1, thereby achieving the effect of adjusting the angle of the impurity removing plate 1, and then helping to adjust the speed at which rice on the impurity removing plate 1 slides off.

[0034] Reference Figure 1 A first bearing 204 is installed on the support rod 203 , and the outer side of the first rotating rod 205 is connected to the inner ring of the first bearing 204 . The first bearing 204 is used to support and assist the first rotating rod 205 to rotate.

[0035] A second bearing 208 is installed on the support block 207 , and the outer side of the second rotating rod 210 is connected to the inner ring of the second bearing 208 . The second bearing 208 is used to assist the second rotating rod 210 in rotating.

[0036] According to the above technical solution, the impurity removing plate 1 can be assisted in adjusting the angle.

[0037] Reference Figure 1 and Figure 3 , a plurality of magnetic steel blocks 7 are installed at the bottom of the impurity removing plate 1, and a quantitative structure 3 is arranged above the impurity removing plate 1. The quantitative structure 3 includes an electric telescopic rod 301, and a first baffle 307 and a second baffle 308 are arranged at the telescopic end of the electric telescopic rod 301. The first baffle 307 and the second baffle 308 are used to inject rice, and the amount of rice on the impurity removing plate 1 at one time can be controlled. According to the above technical scheme, specifically, the rice is poured between the first baffle 307 and the second baffle 308. When the operator observes that the amount of rice is appropriate, the rice is stopped from being injected between the first baffle 307 and the second baffle 308, and the electric telescopic rod 301 is started, so that the telescopic end thereof drives the first baffle 307 and the second baffle 308 to move upward, so that there is a distance between the two and the impurity removing plate 1 for the passage of rice, so that the rice can slide on the impurity removing plate 1 smoothly and quantitatively, avoiding pouring a large amount of rice on the impurity removing plate 1 at one time to affect the magnetic steel block 7 to absorb fine iron filings.

[0038] A plurality of cloth strips 4 are installed on one side of the impurity removing plate 1, and a plurality of magnetic steel sheets 401 are installed on each of the cloth strips 4. When the rice gradually slides down from one side of the impurity removing plate 1, the rice will be more scattered. At this time, the magnetic steel sheets 401 on the cloth strips 4 are more likely to absorb small iron filings, thereby further absorbing the small iron filings.

[0039] According to the above technical scheme, specifically, by pouring a quantitative amount of rice between the first baffle plate 307 and the second baffle plate 308, when the operator observes that the amount of rice is appropriate, the operator stops injecting rice into the space between the first baffle plate 307 and the second baffle plate 308, and starts the electric telescopic rod 301, so that the telescopic end thereof drives the first baffle plate 307 and the second baffle plate 308 to move upward, so that there is a distance between the two and the impurity removing plate 1 for the rice to pass through, so that the rice can slide smoothly and quantitatively on the impurity removing plate 1, avoiding pouring a large amount of rice on the impurity removing plate 1 at one time to affect the magnetic steel block 7 to absorb fine iron filings. As the rice gradually slides from one side of the impurity removing plate 1, the rice will be more dispersed. At this time, the magnetic steel sheet 401 on the cloth strip 4 is more likely to absorb fine iron filings, thereby further absorbing fine iron filings, achieving the purpose of absorbing fine iron filings, and solving the problem that fine iron filings may be mixed in a large amount of rice, which may easily cause the iron filings to not effectively appear within the suction range of the magnetic steel, thereby causing the fine iron filings to not be effectively removed.

[0040] Reference Figure 1 A mounting plate 302 is installed at the top of the electric telescopic rod 301, and a mounting opening is opened on the mounting plate 302 for matching with bolts to fix the mounting plate 302 on the top of the wall, thereby fixing the electric telescopic rod 301 above the debris removal plate 1.

[0041] Reference Figure 1 A feeding plate 5 is installed on the second U-shaped plate 305 , and the rice is poured onto the feeding plate 5 , and the feeding plate 5 guides the rice to fall between the first baffle 307 and the second baffle 308 .

[0042] A vibration motor 6 is installed on the impurity removing plate 1, and the vibration motor 6 is close to the first baffle plate 307 and the second baffle plate 308. When pouring the rice between the first baffle plate 307 and the second baffle plate 308, the vibration motor 6 is started to drive the impurity removing plate 1 to vibrate, thereby driving the rice to vibrate, avoiding the rice from piling up in one place as much as possible, and helping to pour more rice between the first baffle plate 307 and the second baffle plate 308.

[0043] Reference Figure 1 and Figure 4The telescopic end of the electric telescopic rod 301 is installed with a fixed plate 303, and the first U-shaped plate 304 and the second U-shaped plate 305 are installed on the fixed plate 303. The first U-shaped plate 304 and the second U-shaped plate 305 are both rotatably connected with an adjusting rod 306. The first baffle plate 307 and the second baffle plate 308 are respectively installed on the outer sides of the corresponding adjusting rods 306. One end of one adjusting rod 306 is installed with a first roller 309, and one end of the other adjusting rod 306 is installed with a second roller 310. The first roller 309 and the second roller 310 are connected with a first transmission belt 311 for transmission. The fixed plate 303 is installed with a driving motor 312. A shaft 313 is installed at the output end of the driving motor 312, and a third roller 314 is installed at one end of the shaft 313. A fourth roller 315 is installed on one side of the first roller 309. A second transmission belt 316 is connected between the third roller 314 and the fourth roller 315. After the angle of the dust removing plate 1 is adjusted, the driving motor 312 is started to drive the shaft 313 to rotate. The rotation of the shaft 313 drives the transmission of the second transmission belt 316, thereby driving the transmission of the first transmission belt 311, and then driving the angle adjustment of the first baffle 307 and the second baffle 308, which is used to cope with the angle-adjusted dust removing plate 1.

[0044] Working principle:

[0045] The multi-stage impurity removing device starts the hydraulic rod 206 so that its telescopic end drives the support block 207 to move up or down. The movement of the support block 207 drives the movement of one end of the impurity removing plate 1, thereby achieving the effect of adjusting the angle of the impurity removing plate 1, which in turn helps to adjust the speed at which the rice on the impurity removing plate 1 slides down.

[0046] The multi-stage impurity removal device pours a quantitative amount of rice between the first baffle plate 307 and the second baffle plate 308. When the operator observes that the amount of rice is appropriate, the operator stops injecting the rice between the first baffle plate 307 and the second baffle plate 308, and starts the electric telescopic rod 301, so that the telescopic end drives the first baffle plate 307 and the second baffle plate 308 to move upward, so that there is a distance between the first baffle plate 307 and the second baffle plate 308 and the impurity removal plate 1, so that there is a distance between the two and the impurity removal plate 1 for the rice to pass through, so that the rice can slide smoothly and quantitatively on the impurity removal plate 1, avoiding pouring a large amount of rice on the impurity removal plate 1 at one time to affect the magnetic steel block 7 to absorb small iron filings. As the rice gradually slides from one side of the impurity removal plate 1, the rice will be more dispersed. At this time, the magnetic steel sheet 401 on the cloth strip 4 is more likely to absorb small iron filings, thereby further absorbing the small iron filings, thereby achieving the purpose of absorbing the small iron filings.

[0047] After the angle of the debris removing plate 1 is adjusted, the multi-stage debris removing device starts the driving motor 312 to drive the shaft 313 to rotate. The rotation of the shaft 313 drives the transmission of the second transmission belt 316, thereby driving the transmission of the first transmission belt 311, and further driving the angle adjustment of the first baffle plate 307 and the second baffle plate 308, so as to cope with the debris removing plate 1 with angle adjustment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
