Description

Technical Field

[0001] The utility model relates to the technical field of operation, in particular to a multi-stage rice selection device. Background Art

[0002] Rice, also known as paddy rice, is a food made from rice after cleaning, husking, milling, and finished product finishing. Rice is the main food of people in most parts of China. The Chinese utility model patent, authorization announcement number "CN220635329U", discloses a multi-stage rice selection device. The multi-stage rice selection device is driven by a motor to connect a rotating rod, an L-shaped rod, and a transmission plate to rotate and move the rice, which is convenient for rice screening and dropping. When the transmission plate rotates to the left, the screening plate is forced to move downward and contacts the lower screening plate through an adjusting rod, so that the lower screening plate is forced to move at the same time. When the transmission plate rotates to the right, the two screening plates lose force at the same time and are reset by the elasticity of springs and spring sheets, so that the screening plate is vibrated, which is convenient for increasing the dropping speed of rice. The exhaust pipe blows to the rice that is dropping through the control plate to remove dust. The air guide pipe is connected to the annular groove by a ring block, and does not affect the rotation of the rotating rod while guiding the air.

[0003] The above technical solution adds rice into the box through the feed inlet, starts the exhaust pump to introduce the wind into the air duct, and finally introduces the wind into the exhaust duct through through hole 1, through hole 2, and the through hole. The exhaust duct blows the wind toward the rice that is falling through the control plate to remove dust. At this time, the dust is discharged out of the box through the dust exhaust port and handled by the staff. However, the above technical solution still has certain defects. For example, the dust of the above equipment is discharged out of the box through the dust exhaust port and handled by the staff. However, this will cause the dust to be inhaled into the body of the staff, affecting the physical and mental health of the staff, thereby reducing the practicability and safety of the equipment.

[0050] See also Figure 1-3 , the utility model provides a technical solution: a multi-grade rice selection device, comprising a grading box 1;

[0051] A dust collecting device is provided on the grading box 1;

[0052] The dust collection device includes a dust collection box 4, a sliding block 10 and an adsorption plate 15. The outer wall of the dust collection box 4 is provided with a sliding block groove 13, and the sliding block groove 13 is "U"-shaped. The sliding block 10 is slidably connected inside the sliding block groove 13, and the adsorption plate 15 is fixedly connected to the inner wall of the sliding block 10. The left and right outer walls of the sliding block 10 are provided with push block grooves 12, and the insides of the two push block grooves 12 are slidably connected with two push blocks 7. The dust collection box 4 is fixedly connected to the upper surface of the grading box 1, and the upper and lower sides of the sliding block 10 are provided with two first limit block grooves 8. The insides of the two push block grooves 12 are respectively connected to the corresponding first limit block grooves 8. The interior is communicated, and the interiors of the four first limit block grooves 8 are slidably connected to the limit blocks 9. The end of the dust collection box 4 close to the grading box 1 is fixedly extended to the interior of the grading box 1, and the ends of the four push blocks 7 close to the limit blocks 9 are respectively fixedly connected to the outer walls of the corresponding limit blocks 9. Four second limit block grooves 14 are opened in the sliding block groove 13, and the ends of the four limit blocks 9 close to the second limit block grooves 14 are respectively in contact with the inner walls of the corresponding second limit block grooves 14. The interiors of the two push block grooves 12 are each provided with a first return spring 11, and the two ends of the two first return springs 11 are respectively fixedly connected to the outer walls of the corresponding push blocks 7.

[0053] Among them, an inclined plate 2 is fixedly connected to the lower end of the grading box, and the inclined plate 2 is "inclined" inside the grading box 1. Four fixed plates 16 are fixedly connected to the inside of the grading box 1. The four fixed plates 16 are grouped in two, and the two groups of fixed plates 16 are "inclined". Three second return springs 18 are fixedly connected to the upper surfaces of the two groups of fixed plates 16, and the twelve second return springs 18 are grouped in six. A second filter plate 17 is arranged inside the grading box 1, and the second filter plate 17 is "inclined". One end of a group of second return springs 18 at the upper end close to the second filter plate 17 is fixedly connected to the lower surface of the second filter plate 17. A first filter plate 6 is arranged inside the grading box 1, and the first filter plate 6 is "inclined". One end of a group of second return springs 18 at the lower end close to the first filter plate 6 is fixedly connected to the lower surface of the first filter plate 6. Three discharge troughs 5 are opened on the outer wall of the grading box 1, and a feed box 3 is installed on the upper surface of the grading box 1.

[0054] Furthermore, when the device is used, it is started by connecting an external power supply, and the raw material is firstly put into the grading box 1 through the feed box 3, and then the force generated by the raw material falling on the surface of the second filter plate 17 causes the second return spring 18 at the upper end to contract, and then the force generated by the second return spring 18 at the upper end on the second filter plate 17 causes it to swing up and down inside the grading box 1 to filter the raw material once, and at the same time the dust suction box 4 is started, and the dust generated during the filtration is sucked in by the dust suction box 4, and then the dust is processed by the adsorption plate 15 and discharged through the exhaust port of the dust suction box 4, and then the filtered raw material falls on the surface of the first filter plate 6, and the residual raw material on the surface of the second filter plate 17 flows out of the grading box 1 through the inclination of the second filter plate 17 and the discharge chute 5, and then the raw material on the surface of the first filter plate 6 has the same movement trajectory as on the second filter plate 17, and then the raw material passing through the first filter plate 6 falls to the surface of the inclined plate 2, and then flows out of the grading box 1 through the discharge chute 5 again to realize multi-stage screening.

[0055] Furthermore, when the adsorption plate 15 needs to be removed, the push block 7 is pushed to move in the opposite direction to cause the first return spring 11 to contract while driving the limit block 9 to move in the opposite direction, and then the limit block 9 moves in the opposite direction to break contact with the inside of the second limit block groove 14, so that the adsorption plate 15 and the sliding block 10 can be taken out from the inside of the dust box 4.

[0056] The dust generated during filtration is sucked in by the dust suction box 4 in the dust suction device, and then the dust is processed by the adsorption plate 15 and discharged through the exhaust port of the dust suction box 4, thus preventing the dust from being discharged from the outside of the equipment and being inhaled into the body of the staff, which affects their physical and mental health, effectively protecting the physical and mental health of the staff, and at the same time improving the practicability and safety of the equipment, by pushing the push block 7 to move in the opposite direction to drive the first return spring 11 to contract and at the same time drive the limit block 9 to move in the opposite direction, and then the limit block 9 moves in the opposite direction to make it out of contact with the inside of the second limit block groove 14, and then the adsorption plate 15 and the sliding block 10 can be removed from the inside of the dust suction box 4, thus facilitating the disassembly of the adsorption plate 15, facilitating the maintenance and repair of the adsorption plate 15 by the staff, and improving the work efficiency of the staff.

[0057] Working principle: First, the raw material is put into the grading box 1 through the feed box 3, and then the raw material falls on the surface of the second filter plate 17, and the force generated by the second return spring 18 at the upper end contracts. Then, the force generated by the second return spring 18 at the upper end on the second filter plate 17 causes it to shake up and down inside the grading box 1 to filter the raw material once. At the same time, the dust collection box 4 is started, and the dust generated during the filtration is sucked in by the dust collection box 4. Then, the dust is processed by the adsorption plate 15 and discharged through the exhaust port of the dust collection box 4. Then, the filtered raw material falls on the surface of the first filter plate 6, and the residual raw material on the surface of the second filter plate 17 is discharged. The material flows out of the grading box 1 through the inclination of the second filter plate 17 and the discharge chute 5, and then the material on the surface of the first filter plate 6 follows the same movement trajectory as on the second filter plate 17. Then the material passing through the first filter plate 6 falls onto the surface of the inclined plate 2, and then flows out of the grading box 1 through the discharge chute 5 again to achieve multi-stage screening. Then, when it is necessary to remove the adsorption plate 15, the push block 7 is pushed to move in the opposite direction to drive the first return spring 11 to contract and drive the limit block 9 to move in the opposite direction, and then the limit block 9 moves in the opposite direction to break contact with the inside of the second limit block groove 14, so that the adsorption plate 15 and the sliding block 10 can be taken out from the inside of the dust box 4.

[0058] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
