Description

Technical Field

[0001] The invention belongs to the technical field of rice processing, and in particular relates to an impurity removal device for rice production and a use method thereof. Background Art

[0002] Rice is a food made from rice grains after cleaning, husking, milling and finishing. It is the staple food of people in most parts of China. By processing rice after harvesting, the storage time and product quality of rice can be improved.

[0003] After the rice is collected and hulled, it is also necessary to remove impurities such as dust adsorbed on the surface of the rice to prevent quality issues on the rice products.

[0004] A Chinese utility model patent (publication number: CN212821140U) discloses a rice production impurity removal device, comprising a screening box, the bottom of the screening box is connected to a collecting box, the right side of the screening box is fixedly connected to a support plate, the top of the support plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a stirring shaft, the outer surface of the stirring shaft is fixedly connected to a stirring blade, the left side of the outer surface of the screening box is connected to a waste connecting cylinder, the right side of the screening box is fixedly connected to a connecting box, the interior of the connecting box is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a fan. The utility model can scatter the rice in the process of falling by cooperating between the stirring shaft of the first motor and the stirring blade, and can blow the dust in the scattered rice into the waste connecting cylinder in cooperation with the second motor and the fan, so as to collect the waste in the rice and prevent the dust and waste from being scattered into the atmosphere and mixed in the rice.

[0005] Although the above patent stirs the input rice through the setting of the screening box and the collecting box through the stirring blades, separates the impurities in the rice through continuous stirring, and then blows the impurities in the rice through the fan of the second motor to separate the impurities from the rice, but in the production and processing of rice, it is often necessary to continuously feed the impurity removal device. Therefore, when more rice enters the screening box at the same time, the stirring shaft at the output end of the first motor can only stir the rice once through the blades, and as the blades rotate, most of the rice will rotate with the rotation of the blades, and the rice cannot be effectively dispersed by collision, so that the impurities in the rice cannot be separated. Therefore, when feeding continuously, the stirring blades cannot continuously turn the rice, so that the rice will quickly fall to the bottom, which is not conducive to improving the separation quality of impurities.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0034] Example 1

[0035] like Figure 1-5 As shown, a rice production impurity removal device includes a chassis 1, a feeding mechanism 2, a screening mechanism 3, a transmission mechanism 5, a shoveling mechanism 4, an adsorption mechanism 6, and a feeding mechanism 7. The chassis 1 is vertically arranged; the feeding mechanism 2 is arranged at the top of the chassis 1, and its lower part is connected to the inside of the chassis 1; the screening mechanism 3 is arranged in the chassis 1, and its two sides are movably connected to the two sides of the chassis 1; the shoveling mechanism 4 is arranged in the chassis 1, located above the screening mechanism 3, and connected to the screening mechanism 3 through the transmission mechanism 5; the feeding mechanism 7 is arranged in the chassis 1, located below the screening mechanism 3, and its bottom passes through the side wall of the chassis 1. The rice enters the chassis 1 from the feed hopper 21 and falls onto the screening mechanism 3. The screening mechanism 3 performs up and down reciprocating motion, driving the rice to vibrate up and down, so as to separate the rice from the impurities. When the screening mechanism 3 is in motion, the shoveling mechanism 4 is driven to move through the transmission mechanism 5. The shoveling mechanism 4 turns the rice to improve the dispersion of the rice and the impurities. During the vibration and turning of the rice, the impurities are sucked out and collected by the adsorption mechanism 6, and the rice falls from the screening mechanism 3 into the unloading mechanism 7, and the rice is collected by the unloading mechanism 7.

[0036] The feeding mechanism 2 includes a feeding hopper 21; the feeding hopper 21 is arranged on the top of the chassis 1, and the lower part thereof is connected to the interior of the chassis 1. Unprocessed rice enters the interior of the chassis 1 through the feeding hopper 21.

[0037] The screening mechanism 3 includes a sieve plate 31 and a cylinder 32; the left and right side walls of the chassis 1 are provided with limit slots 11; the sieve plate 31 is horizontally arranged, and its left and right ends are located in the limit slots 11 of the inner wall of the chassis 1. The sieve plate 31 is provided with a plurality of sieve holes 311, and the limit slots 11 can ensure that the sieve plate 31 can only vibrate up and down in the vertical direction; the cylinder 32 is vertically arranged in the chassis 1, and its bottom end is fixedly connected to the right side of the bottom surface of the chassis 1, and the output end is fixedly connected to the bottom surface of the sieve plate 31. The cylinder 32 performs up and down reciprocating motion, driving the sieve plate 31 to vibrate up and down, and vibrating the rice falling on the sieve plate 31, so that the rice is separated from impurities such as dust adsorbed on the rice, and the rice after impurities removal falls from the sieve holes 311.

[0038] The screening mechanism 3 also includes a spring 33; the spring 33 is vertically arranged in the limiting groove 11 and is located at the top and bottom surfaces of the sieve plate 31. The end of the spring 33 close to the sieve plate 31 is fixedly connected to the sieve plate 31, and the end away from the sieve plate 31 is fixedly connected to the limiting groove 11; the spring 33 is used for buffering. When there are unexpected situations such as uneven feeding, collision of larger impurities, etc. that generate additional impact force, the spring 33 can absorb these impact forces through its own elastic deformation to prevent the sieve plate 31 from being damaged due to excessive force.

[0039] The shoveling mechanism 4 includes a rotating shaft 41, a shovel plate 42, and an axle seat 43; the axle seat 43 is vertically arranged on the left and right side walls of the chassis 1 and is located above the sieve plate 31, and a bearing is arranged inside it; the rotating shaft 41 is horizontally arranged on the left and right sides, and its two ends are connected to the inner ring of the bearing in the axle seat 43, the rotating shaft 41 can rotate on the axle seat 43, and the right end of the rotating shaft 41 extends out of the right side wall of the chassis 1 and can rotate on the right side wall of the chassis 1; the shovel plate 42 is an arc structure, the upper part of which is fixedly connected to the rotating shaft 41, and the lower part is oriented toward the left and right center line direction of the sieve plate 31. The arc mechanism of the shovel plate 42 is conducive to the shovel plate 42 to better contact with the rice on the sieve plate 31 during rotation, and to flip the rice from the sieve plate 31, thereby improving the dispersion of rice and impurities. When the sieve plate 31 moves, the transmission mechanism 5 drives the rotating shaft 41 to rotate on the shaft seat 43, and the rotating shaft 41 drives the shovel plate 42 to rotate based on the rotating shaft 41, so that the lower end of the sieve plate 31 performs a circular motion, thereby turning the rice on the sieve plate 31. During the vibration of the sieve plate 31, some impurities may be covered or wrapped by the rice. Through the turning of the shovel plate 42, these covered impurities can be exposed, so that the adsorption mechanism 6 can more effectively absorb the impurities. At the same time, turning also helps to prevent rice from piling up on the sieve plate 31, ensuring that the rice can be evenly distributed on the sieve plate 31, thereby improving the impurity removal efficiency.

[0040] The two shoveling mechanisms 4 are provided, and are spaced apart in the front and rear of the chassis 1. The two shoveling mechanisms 4 can improve the turning effect.

[0041] The transmission mechanism 5 includes a connecting plate 51, a toothed disc 52, and a rack 53; a through slide 12 is provided on the limit groove 11 corresponding to the right side wall of the chassis 1, and the slide 12 is located between the two shoveling mechanisms 4; the connecting plate 51 is horizontally arranged left and right, and its left end is fixedly connected to the right end of the screen plate 31, and the right end extends out of the slide 12 to the right; two toothed discs 52 are vertically arranged, and the middle parts of the two toothed discs 52 are respectively fixedly connected to the right ends of the rotating shafts 41 of the two shoveling mechanisms 4; the rack 53 is vertically arranged, and the lower part of the left side surface is fixedly connected to the connecting plate 51, and the upper left and right sides are respectively meshed with the two toothed discs 52. When the sieve plate 31 vibrates up and down, it drives the connecting plate 51 to move up and down, and the connecting plate 51 drives the rack 53 to move up and down, so that the toothed disc 52 meshed with the rack 53 rotates, and the rotation of the toothed disc 52 drives the rotating shaft 41 of the shoveling mechanism 4 to rotate, so that the shovel plate 42 moves based on the rotating shaft 41. The transmission mechanism 5 is used to drive the shoveling mechanism 4 to move when the screening mechanism 3 moves, without the need for an additional power source, thereby reducing costs and improving the impurity removal effect.

[0042] The adsorption mechanism 6 includes a fan 61, a collection box 62, and a collection pipe 63; an opening 13 is provided on the upper part of the left side wall of the chassis 1; the fan 61 is arranged on the opening 13 of the left side wall of the chassis 1; the collection box 62 is arranged on the left side of the chassis 1, and its top is connected to the fan 61 through the collection pipe 63. During the up and down vibration separation process of rice and impurities, the fan 61 sucks out the impurities, and enters the collection box 62 through the collection pipe 63, so that the impurities are collected in the collection box 62 and processed centrally.

[0043] The feeding mechanism 7 includes a feeding hopper 71 and a feeding pipe 72; the feeding hopper 71 is arranged in the chassis 1 and below the sieve plate 31; the upper end of the feeding pipe 72 is connected to the bottom of the feeding hopper 71, and the lower end extends to the left side of the left wall of the chassis 1. The rice after impurities removal enters the feeding hopper 71 through the sieve holes 311 on the sieve plate 31, and is discharged and collected from the feeding pipe 72.

[0044] The working mode of this embodiment is as follows.

[0045] The rice is fed into the chassis 1 through the feed hopper 21 disposed on the top of the chassis 1 and connected to the inside of the chassis 1, and falls on the sieve plate 31 of the screening mechanism 3. Subsequently, the cylinder 32 in the screening mechanism 3 starts to make up and down reciprocating motions, driving the sieve plate 31 to vibrate up and down in the limit grooves 11 on the left and right side walls of the chassis 1. During this process, the spring 33 assists the sieve plate 31 to move stably and buffer, and the rice and impurities jump and roll on the sieve plate 31 accordingly, and the impurities are gradually separated from the rice and are in a state that is easy to be adsorbed. At the same time, the movement of the sieve plate 31 is transmitted to the rack 53 through the connecting plate 51 fixedly connected at the right end, so that the rack 53 moves up and down, and the two toothed discs 52 meshing with the rack 53 rotate under the action of the sieve plate 31, thereby driving the rotating shaft 41 of the shoveling mechanism 4 fixedly connected to the middle part of the toothed disc 52 to rotate on the shaft seat 43, and the rotating shaft 41 drives the shovel plate 42 to make a circular motion, and the shovel plates 42 of the two shoveling mechanisms 4 arranged at intervals in front and behind turn the rice, so that the rice and impurities are fully mixed and separated. In the process of the rice and impurities vibrating and turning up and down, the fan 61 of the adsorption mechanism 6 works to generate suction, suck out the separated impurities, and send them to the collection box 62 for collection through the collection pipe 63. Finally, the rice after impurity removal falls into the lower hopper 71 in the chassis 1 through the sieve hole 311 of the sieve plate 31, and then is discharged from the left wall of the chassis 1 through the lower pipe 72 to complete the collection.

[0046] Example 2

[0047] A method for using an impurity removal device for rice production comprises the following steps: firstly placing a device for collecting rice at one end of a feeding pipe 72 extending out of a chassis 1; starting a fan 61 to prepare for adsorbing impurities; starting a cylinder 32, which starts to make an up-and-down reciprocating motion, and driving a sieve plate 31 to vibrate up and down; slowly pouring rice to be removed from the feeding hopper 21, so that the rice enters the chassis 1 from the feeding hopper 21, and as the rice enters the sieve plate 31, the rice and impurities are separated by the vibration of the sieve plate 31, and during the movement of the sieve plate 31, the shoveling motion of a shoveling mechanism 4 is driven by a transmission mechanism 5, so that the rice and impurities are further separated, the impurities are sucked out and enter a collecting box 62 through a collecting pipe 63, and the rice falls from the sieve plate 31 into the feeding device, and enters the rice collecting device from the feeding pipe 72, and the impurity removal is completed.
