DETAILED DESCRIPTION
[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.
[0026] Example 1: A dust recovery device for rice processing, referring to Figure 1-Figure 4, including a shell 1, a discharge port is opened at the bottom of the shell 1, a funnel 11 is connected to the right side of the top of the shell 1, the right side of the bottom of the shell 1 is inclined, a rice collecting frame 12 is slidably connected to the lower part of the shell 1, a fan 13 is installed on the left side of the top of the shell 1, the input end of the fan 13 faces the inside of the shell 1, a dust collecting frame 14 is installed on the left side of the shell 1, a conveying pipe 15 is connected between the top of the dust collecting frame 14 and the output end of the fan 13, a drawer 16 is slidably connected to the inside of the dust collecting frame 14, a first retention plate 2 is fixedly connected to the right side of the upper inner part of the shell 1, and a first retention plate 2 is slidably connected to the left side of the upper inner part of the shell 1 Two retention plates 21, the inner bottoms of the first retention plate 2 and the second retention plate 21 are both inclined, the left side of the first retention plate 2 is slidably connected to a particle collecting frame 29, the rear side of the outer shell 1 is fixedly connected to a motor 22, the output shaft of the motor 22 is fixedly connected to a cam 23, the eccentric position of the cam 23 is fixedly connected to a push rod 24, the left part of the first retention plate 2 is slidably connected to a dispersion rod 25, the left part of the first retention plate 2 is fixedly connected to a blocking rod 26, the rear side of the outer shell 1 is slidably connected to a connecting rod 27, the push rod 24 passes through the connecting rod 27 and contacts and cooperates with the connecting rod 27, and the connecting rod 27 is fixedly connected to the dispersion rod 25 and the second retention plate 21.
[0027] Preferably, the positions of the blocking rod 26 and the dispersion rod 25 are distributed in a stepped shape.
[0028] Preferably, a filter is provided on the particle collection frame 29, and the pore size of the filter is smaller than that of the rice.
[0029] Preferably, two guide plates 20 are further included. The two guide plates 20 are respectively fixed to the front and rear sides of the inner bottom of the housing 1 , and the inner sides of the two guide plates 20 are both inclined.
[0030] When in use, the motor 22 is started, the output shaft of the motor 22 drives the cam 23 to rotate, and the cam 23 drives the push rod 24 to rotate. Since the push rod 24 is arranged at the eccentric position of the cam 23, the push rod 24 drives the connecting rod 27 to move back and forth during the rotation of the push rod 24, and the connecting rod 27 drives the dispersion rod 25 and the second retention plate 21 to move back and forth. The rice is manually poured into the funnel 11, so that the rice falls on the first retention plate 2. Since the inner bottoms of the first retention plate 2 and the second retention plate 21 are inclined, the rice is The rice finally falls into the rice collecting frame 12 under the guidance of the first retention plate 2 and the second retention plate 21. Since the right side of the inner bottom of the shell 1 is inclined and two guide plates 20 are arranged on the right side of the inner bottom of the shell 1, the rice finally falls into the rice collecting frame 12 under the guidance of the inclined surface of the right side of the inner bottom of the shell 1 and the guide plates 20. At the same time, the fan 13 is started. The fan 13 extracts the flying dust inside the shell 1 through suction. The dust enters the dust collecting frame 14 through the conveying pipe 15 and finally falls into the drawer 16.
[0031] When the rice on the first retention plate 2 slides to the left and contacts the dispersion rod 25 and the baffle rod 26, the baffle rod 26 and the dispersion rod 25 are distributed in a stepped shape, so that the rice passes between the baffle rod 26 and the dispersion rod 25, thereby increasing the amount of rice passing through and slowing down the speed at which the rice passes through. When the dispersion rod 25 reciprocates back and forth, the friction between the dispersion rod 25 and the rice disperses the rice that has passed through. When the dispersed rice passes through the particle collecting frame 29, since the particle collecting frame 29 is provided with a filter screen, the aperture of the filter screen is smaller than that of the rice, so that the particles and dust in the rice fall into the particle collecting frame 29, thereby performing preliminary dust removal on the rice.
[0032] When the scattered rice falls on the second retention plate 21, the second retention plate 21 moves back and forth so that the second retention plate 21 rolls the rice thereon, so that the rice can collide with each other, causing the dust on the rice to fall and fly. In this way, by reducing the amount of rice passing through and slowing down the speed of the rice passing through, the rice is dispersed, and then the dust is initially recovered, and finally the dust is recovered by collision. The overall structure can effectively recover the dust and ensure the dust recovery effect.
[0033] After the dust is recovered, the motor 22 and the fan 13 are turned off, and the drawer 16 and the particle collection frame 29 are taken out, so that the dust and particles in the drawer 16 and the particle collection frame 29 can be recovered.
[0034] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , also includes an opening and closing plate 17, the opening and closing plate 17 is rotatably connected to the bottom of the funnel 11, and two torsion springs 18 are fixedly connected between the opening and closing plate 17 and the funnel 11.
[0035] When the rice is poured into the hopper 11, the rice falls on the opening and closing plate 17, and the opening and closing plate 17 rotates downward due to the gravity of the rice, so that the rice can fall onto the first retention plate 2, and the torsion spring 18 is deformed. When there is no rice on the opening and closing plate 17, the opening and closing plate 17 is driven to close the bottom of the funnel 11 under the action of the torsion spring 18 returning to its original position, so as to prevent the flying dust from floating out through the funnel 11 and polluting the environment.
[0036] Reference Figure 1 , Figure 2 and Figure 3 , and also includes two fans 19, both of which are installed in the shell 1 and are respectively located below the first retention plate 2 and the second retention plate 21. The two fans 19 are both inclined, and a ventilation net 10 is installed on the lower left side of the shell 1.
[0037] The fan 19 is started and air is taken in through the ventilation net 10. The rice dropped from the first retention plate 2 has dust generated during its falling process blown to the bottom of the fan 13 by the upper fan 19. The rice dropped from the second retention plate 21 has dust generated during its falling process blown to the upper fan 19 by the lower fan 19 and then blown to the bottom of the fan 13 by the upper fan 19, thereby further ensuring the dust recovery effect.
[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , and also includes protrusions 28 distributed at equal intervals horizontally, and the protrusions 28 distributed at equal intervals horizontally are all fixed to the bottom of the second retention plate 21.
[0039] When the second retention plate 21 moves back and forth, the second retention plate 21 drives the protrusion 28 to move back and forth. When rice falls on the second retention plate 21, the protrusion 28 disperses the rice and collides with the rice to further separate the dust on the rice, thereby ensuring the dust recovery effect.
[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , also includes two water pipes 31, the two water pipes 31 are rotatably connected to the upper part of the dust collecting frame 14, the inner sides of the two water pipes 31 are connected to atomizing nozzles 34 distributed in a straight line with equal intervals, a connecting pipe 3 is installed on the dust collecting frame 14, the two water pipes 31 are rotatably connected to the connecting pipe 3, a connecting plate 32 is fixedly connected to the left end of the connecting rod 27, the connecting plate 32 is fixedly connected to two threaded sleeves 33, the rear ends of the two water pipes 31 are provided with threaded grooves, and the threaded grooves of the two water pipes 31 are threadedly connected with threaded sleeves 33.
[0041] The connecting pipe 3 is connected with an external water pipe, and water is delivered to the connecting pipe 3 through the water pipe. The water enters the water pipe 31 and is sprayed out by the atomizing nozzle 34 to wet the dust entering the dust collecting frame 14. When the second retention plate 21 moves back and forth, the second retention plate 21 drives the connecting plate 32 to move back and forth, and the connecting plate 32 drives the threaded sleeve 33 to move back and forth. The threaded sleeve 33 drives the water pipe 31 to swing back and forth through the threaded groove, and the water pipe 31 drives the atomizing nozzle 34 to swing back and forth, so that when the atomizing nozzle 34 sprays water, the water spraying range of the atomizing nozzle 34 is increased, so that the dust entering the dust collecting frame 14 can fully contact with the mist water, accelerate the speed at which the dust falls into the drawer 16, improve work efficiency, and prevent dust from flying when manually recovering the dust in the drawer 16.
