Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology in rice processing, and in particular to an impurity screening and removal device for rice processing. Background Technology

[0002] Rice, also known as paddy rice, is a finished grain made from the mature grains of the rice plant (Oryza sativa) after hulling, milling, and other processing. It is one of the three major staple foods for humans. Rice contains 70-80% carbohydrates, which is the main source of energy, as well as 6-8% protein and B vitamins. As the staple food of half the world's population, it occupies a core position in Asian diets.

[0003] When processing rice, it is necessary to separate impurities from the raw materials before proceeding with other processing steps to produce the finished product. Existing methods for removing impurities by screening plates usually separate rice from impurities, but these methods have significant limitations. They cannot screen both large impurities and fine dust impurities, which can affect subsequent processing. In addition, a large amount of rice accumulating on the screening plate during screening can reduce screening efficiency and fail to meet the needs of workers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rice processing impurity screening and removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice processing impurity screening and removal device includes an impurity removal main body with a feed pipe installed on it. Two screening structures are installed inside the main body. Each screening structure includes a stabilizing block fixedly mounted on the main body, multiple springs (first type) fixedly mounted on the stabilizing block, and a screening plate fixedly mounted on the multiple springs (first type) at an angle. A slot is formed in the main body, and multiple springs (second type) are fixedly mounted within the slot. A lifting plate is fixedly mounted on the multiple springs (second type), with its sidewall fixedly mounted on the screening plate. A rotating shaft (first type) is rotatably mounted on the stabilizing block, and a rotating shaft (second type) is rotatably mounted on the main body. Eccentric protrusions are fixedly mounted on both rotating shafts (first type and second type), and spur gears are fixedly mounted at one end of each rotating shaft (first type and second type). The two spur gears mesh and drive each other. A control mechanism for controlling the movement of the screening structures is installed on the main body.

[0007] Preferably, the control mechanism includes a rotary motor fixedly mounted on the impurity removal body, the output shaft of the rotary motor being fixedly mounted on one of the rotating shafts, and the rotating shafts of one of the screening structures being connected to the rotating shafts of the other screening structure via a belt drive assembly.

[0008] Preferably, the feed pipe has a groove, and a baffle plate is slidably connected in the groove. A reciprocating screw is threaded through the baffle plate. The reciprocating screw is rotatably connected to the feed pipe. The reciprocating screw is connected to the rotating shaft of one of the screening structures through a belt drive assembly.

[0009] Preferably, the impurity removal body has an opening corresponding to the screening plate, and two sliding grooves are fixedly installed in the opening. The two sliding grooves are fixedly installed on the stabilizing block, and the two sliding grooves are slidably connected to a storage box one. The impurity removal body is equipped with a double hinged door, and a storage box two is slidably connected inside the impurity removal body.

[0010] Preferably, a plurality of pads are fixedly installed at the lower end of the impurity removal body, and the lower ends of the plurality of pads are all provided with anti-slip textures.

[0011] Preferably, each of the two storage boxes is fixedly equipped with a handle.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by setting two screening plates with different screen hole sizes, large and small impurities can be separated from rice more thoroughly, and the screening speed can be accelerated by the vibration of the screening plates.

[0013] 2. By driving the baffle plate to slide in the chute through the reciprocating screw, the feed pipe can be opened and closed in a cyclical manner. This allows for the quantitative measurement of rice entering the screening plate, effectively preventing excessive rice from accumulating on the screening plate and slowing down the screening rate.

[0014] 3. By setting up storage box one and storage box two, large impurities, small impurities and rice can be stored separately, making it convenient for staff to process them separately, reducing the collection time of staff and improving work efficiency. Attached Figure Description

[0021] Reference Figures 1-5 A rice processing impurity screening and removal device includes a main body 1, a feed pipe 2 installed on the main body 1, and two screening structures installed inside the main body 1. Each screening structure includes a stabilizing block 3 fixedly installed on the main body 1, and multiple springs 4 fixedly installed on the stabilizing block 3. A screening plate 5 is fixedly installed on each of the multiple springs 4. The screening holes between the two screening plates 5 are of different sizes; the upper screening plate 5 has larger screening holes, which can screen out impurities larger than rice grains, while the lower screening plate 5 has smaller screening holes, which can separate impurities smaller than rice grains from the rice, achieving a more thorough separation of impurities. The screening plates 5 are installed at an angle, allowing for more thorough separation of impurities. After screening, the impurities and rice are transported to the collection box 17 through the screening plate 5 to complete the collection. The impurity removal body 1 has a slot, and multiple springs 2 6 are fixedly installed in the slot. The multiple springs 2 6 are fixedly installed together with the lifting plate 7. The side wall of the lifting plate 7 is fixedly installed on the screening plate 5. The stabilizing block 3 is rotatably installed with a rotating shaft 1 8. The impurity removal body 1 is rotatably installed with a rotating shaft 2 9. Both the rotating shaft 1 8 and the rotating shaft 2 9 are fixedly installed with an eccentric protrusion 10. One end of the rotating shaft 1 8 and the rotating shaft 2 9 are fixedly installed with a spur gear 11. The two spur gears 11 mesh with each other for transmission. The impurity removal body 1 is equipped with a control mechanism to control the movement of the screening structure.

[0022] The control mechanism drives a rotating shaft 8 to rotate. The rotating shaft 8 drives the rotating shaft 9 to rotate through the meshing transmission between the spur gears 11. This drives the two eccentric protrusions 10 to rotate simultaneously, thus raising and lowering the screening plate 5. The screening plate 5 is stabilized under the elastic force of the spring 4 and rises and falls stably with the cooperation of the lifting plate 7. It is further stabilized with the cooperation of the spring 6. The control mechanism enables the rotating shafts 8 and 9 in the two screening structures to rotate simultaneously, completing the simultaneous vibration screening of the two screening plates 5.

[0023] The control mechanism includes a rotary motor 12 fixedly mounted on the impurity removal body 1. The output shaft of the rotary motor 12 is fixedly mounted on one of the rotating shafts 8. The rotating shaft 8 of one screening structure is connected to the rotating shaft 9 of another screening structure through a belt drive assembly 13. The belt drive assembly 13 consists of two pulleys and a belt body.

[0024] By starting the rotary motor 12, the rotating shaft 8 is driven to rotate, and with the cooperation of the spur gear 11, the rotating shaft 9 is driven to rotate. With the cooperation of the belt drive assembly 13, the other rotating shaft 8 is driven to rotate, so that the two rotating shafts 8 and the rotating shaft 9 rotate simultaneously.

[0025] A chute is provided on the feed pipe 2, and a baffle plate 14 is slidably connected in the chute. A reciprocating screw 15 is threaded through the baffle plate 14. The reciprocating screw 15 is rotatably connected to the feed pipe 2. The reciprocating screw 15 is connected to the rotating shaft 9 of one of the screening structures through a belt drive assembly 16. The belt drive assembly 16 consists of two pulleys and a belt body. The upper pulley is larger and the lower pulley is smaller. Therefore, after the lower pulley rotates multiple times, the upper pulley rotates once. This allows the screening plate 5 to completely complete the current rice screening work.

[0026] The rotation of the belt drive assembly 16 and the rotating shaft 9 drives the reciprocating screw 15 to rotate, thereby causing the connected baffle plate 14 to slide into the chute and then slide out to complete the cyclic rice feeding step. The process is uniform and cyclical, so the raw material fed in each time is quantitative, which is convenient for screening.

[0027] The impurity removal body 1 has an opening corresponding to the screening plate 5. Two sliding grooves are fixedly installed in the opening. The two sliding grooves are fixedly installed on the stabilizing block 3. The two sliding grooves are slidably connected to the storage box 17. The impurity removal body 1 is equipped with a double hinge door 18. The double hinge door 18 is existing technology and has two hinges, which can open and close the two door panels. The impurity removal body 1 is slidably connected to the storage box 19.

[0028] Large impurities and rice enter the first collection box 17 through the inclined sieve plate 5. The staff can quickly take out and collect the first collection box 17 through the sliding groove. The second collection box 19 can be taken out by opening the double hinge door 18, and small impurities can be collected.

[0029] Multiple feet are fixedly installed at the lower end of the main body 1 for removing impurities. The lower end of each foot is equipped with anti-slip texture. The feet can be used to stably place the entire device in the designated position. Each of the two storage boxes 17 is fixedly installed with a handle. The storage box 17 can be quickly pulled to complete the collection work.

[0030] In this invention, the working principle is as follows: Starting the rotary motor 12 drives a rotating shaft 8 to rotate. The rotating shaft 8, through the meshing transmission between spur gears 11, drives a second rotating shaft 9 to rotate, thereby simultaneously rotating the two eccentric protrusions 10. This allows the screening plate 5 to be raised and lowered. The screening plate 5 is stabilized by the elastic force of spring 4 and, with the cooperation of the lifting plate 7, steadily rises and falls. Further stabilization is achieved with the cooperation of spring 6, driving the rotating shaft 8 to rotate. In turn, with the cooperation of the spur gears 11, the second rotating shaft 9 rotates. Finally, with the cooperation of the belt drive assembly 13, the other rotating shaft 8 rotates, thus enabling the two rotating shafts 8 to rotate. Simultaneously rotating with shaft 2 9, shafts 1 8 and 2 9 in the two screening structures rotate at the same time, completing the simultaneous vibration screening of the two screening plates 5. Through belt drive assembly 2 16, the rotation of shaft 2 9 drives the reciprocating screw 15 to rotate, thereby causing the connected baffle plate 14 to slide into the chute and then slide out, completing the cyclic rice feeding step. The process is uniform and cyclical, so the raw material fed in each time is quantitative, which is convenient for screening. Through the inclined screening plate 5, large impurities and rice enter the collection box 1 17. The staff can quickly take out and collect the collection box 1 17 through the sliding chute. By opening the double hinge door 18, the collection box 2 19 can be taken out to collect small impurities.
