Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a dust-collecting rice processing shell suction device. Background Technology

[0002] Rice needs to be hulled to become the rice we eat every day. The principle of a rice hulling machine is that rice with husks enters the milling chamber from the hopper and is ground by grinding wheels. Inside the hulling machine, the rice husks are repeatedly impacted by impellers, loosening and breaking off. After screening, the rice is discharged from the outlet. Finally, some of the husks and bran removed during the grinding process are discharged from the milling chamber through the bran sieve, while the rest are removed by the airflow from the bran remover as the grain exits from the outlet. Therefore, some bran and broken husks are still mixed in when the rice is discharged, affecting its quality and needing to be removed.

[0003] Chinese patent CN220696840U discloses a dust-collecting rice processing shell suction device. It uses a dust-collecting fan to draw in dust, creating a negative pressure inside the outer filter chamber via the fan and dust collection pipe. Air, along with the rice, enters the inner filter mesh directly through the feed hopper. The inner filter mesh filters out the rice and any embedded shell fragments. The shell fragments pass through the inner filter mesh, are collected by the dust collection pipe, and are then extracted into the dust collection box via the outlet pipe. This achieves efficient dust and shell fragment filtration of the rice through a dust-collecting process.

[0004] After prolonged use, some broken shells may accumulate in the mesh of the filter inner mesh in the aforementioned patent documents, causing clogging and affecting the filtration effect of the mesh. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: after long-term use, some broken shells may accumulate in the mesh of the filter inner mesh of the existing vacuum-type rice processing vacuum device, which will cause the mesh to be blocked and affect the filtration effect of the mesh. Therefore, a vacuum-type rice processing shell suction device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust-collecting rice processing shell suction device includes a box, a filter inner mesh cover is fixedly installed inside the box, a rotating rod is horizontally rotatably installed inside the box, a plurality of stirring blades are fixedly installed on the surface of the rotating rod in a circumferential shape, the rotating rod is located inside the filter inner mesh cover, one end of the rotating rod extends out of the box and is fixedly installed with a reciprocating lead screw, and the rotating rod is controlled to rotate by a drive assembly.

[0008] The box body has symmetrical openings on its side walls. A sliding rod is slidably inserted into each opening. An impact rod is fixedly installed at one end of the sliding rod inside the box body, and an installation plate is fixedly installed at the other end outside the box body. The installation plate is connected to the box body via a telescopic component. A rotating opening is provided on the upper surface of the installation plate. A rotating shaft is rotatably installed in the rotating opening. An inclined plate is fixedly installed at the bottom end of the rotating shaft, and a circular installation block is fixedly installed at the top end of the rotating shaft. The installation block is connected to the installation plate via an elastic component. A limiting component is provided on the upper surface of the installation plate to restrict the rotation direction of the inclined plate. A sliding plate is threaded onto the reciprocating screw. A stop rod is symmetrically fixedly installed on the surface of the sliding plate. Two inclined plates are located on the movement paths of two stop rods. A limiting rod is symmetrically fixedly installed on the surface of the box body, and the sliding plate is slidably fitted onto the two limiting rods.

[0009] Preferably, the drive assembly includes a drive motor, a U-shaped seat is fixedly mounted on the surface of the housing, the drive motor is fixedly mounted on the surface of the U-shaped seat, and the output shaft of the drive motor is fixedly connected to a reciprocating lead screw.

[0010] Preferably, the telescopic component includes a telescopic spring sleeved on the slide rod, with both ends of the telescopic spring fixedly connected to the mounting plate and the housing, respectively.

[0011] Preferably, the elastic component includes a torsion spring sleeved on the rotating shaft, with both ends of the torsion spring fixedly connected to the mounting block and the mounting plate, respectively.

[0012] Preferably, the limiting component includes a stop bar that is vertically fixedly mounted on the upper surface of the mounting plate, and a rectangular block is fixedly mounted on the side wall of the mounting block, with the stop bar located on the rotation path of the rectangular block.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A dust-collecting rice processing shell suction device includes a housing 1, a filter inner mesh cover 2 fixedly installed inside the housing 1, a rotating rod 3 horizontally rotatably installed inside the housing 1, and multiple stirring blades 4 fixedly installed on the surface of the rotating rod 3 in a circumferential shape. The rotating rod 3 is located inside the filter inner mesh cover 2, one end of the rotating rod 3 extends out of the housing 1 and is fixedly installed with a reciprocating screw 5. The rotating rod 3 is controlled to rotate by a drive assembly, which includes a drive motor 14. A U-shaped seat is fixedly installed on the surface of the housing 1, and the drive motor 14 is fixedly installed on the surface of the U-shaped seat. The output shaft of the drive motor 14 is fixedly connected to the reciprocating screw 5.

[0025] Symmetrical openings are provided on the side walls of the housing 1. A sliding rod 6 is slidably inserted into each opening. An impact rod 7 is fixedly installed at one end of the sliding rod 6 inside the housing 1, and an installation plate 8 is fixedly installed at the other end outside the housing 1. The installation plate 8 is connected to the housing 1 via a telescopic component. The telescopic component includes a telescopic spring 15 sleeved on the sliding rod 6. Both ends of the telescopic spring 15 are fixedly connected to the installation plate 8 and the housing 1, respectively. In the initial state, the impact rod 7 will abut against the surface of the filter inner mesh cover 2 under the elastic potential energy of the telescopic spring 15. A rotating opening is provided on the upper surface of the installation plate 8. A rotating shaft 9 is rotatably installed in the rotating opening. An inclined plate 10 is fixedly installed at the bottom end of the rotating shaft 9, and a circular installation block 11 is fixedly installed at the top end of the rotating shaft 9. The installation block 11 is connected via an elastic... The component is connected to the mounting plate 8. The elastic component includes a torsion spring 16 sleeved on the rotating shaft 9. The two ends of the torsion spring 16 are fixedly connected to the mounting block 11 and the mounting plate 8 respectively. The upper surface of the mounting plate 8 is provided with a limiting component for limiting the rotation direction of the inclined plate 10. The limiting component includes a stop bar 18 vertically fixedly installed on the upper surface of the mounting plate 8. A rectangular block 19 is fixedly installed on the side wall of the mounting block 11. The stop bar 18 is located on the rotation path of the rectangular block 19. A sliding plate 12 is threaded onto the reciprocating screw 5. A stop bar 13 is symmetrically fixedly installed on the surface of the sliding plate 12. The two inclined plates 10 are located on the movement paths of the two stop bars 13 respectively. A limiting bar 17 is symmetrically fixedly installed on the surface of the housing 1. The sliding plate 12 is slidably sleeved on the two limiting bars 17.

[0026] When the drive motor 14 is started, its output shaft will rotate the rotating rod 3, the reciprocating screw 5, and the multiple agitator blades 4. The multiple agitator blades 4 will agitate the rice and broken husks inside the filter inner mesh cover 2, ensuring that the rice is fully separated from the dust and broken husks. As the reciprocating screw 5 rotates, the sliding plate 12 threaded onto the reciprocating screw 5 will also move laterally back and forth with the two abutment rods 13 under the restriction of the two limiting rods 17. During the movement, the surfaces of the two abutment rods 13 will slide into contact with the inclined surfaces of the two inclined plates 10. Due to the restriction of the rectangular block 19 and the stop rod 18, the end of the inclined plate 10 away from the rotating shaft 9 cannot rotate away from the housing 1. Therefore, under the pressure of the inclined surface, the two sliding rods 6 will separate. Do not move the two impact rods 7 away from each other. The two telescopic springs 15 will be stretched at this time. Then, as the abutment rod 13 moves, when the abutment rod 13 is no longer in contact with the inclined plate 10, the pressure force exerted by the abutment rod 13 on the inclined plate 10 disappears. The slide rod 6 and the impact rod 7 will move and reset quickly under the elastic potential energy of the telescopic spring 15. The two impact rods 7 will collide with the surface of the filter inner mesh cover 2. Then, when the abutment rod 13 moves in the opposite direction to the previous moving direction, the abutment rod 13 will abut against the surface of the inclined plate 10. At this time, under the pressure of the abutment rod 13, the end of the inclined plate 10 away from the rotating shaft 9 will rotate towards the box 1. Then, when the abutment rod 13 is no longer abutting against the inclined plate 10, the inclined plate 10 will quickly rotate and reset under the elastic potential energy of the torsion spring 16.

[0027] When the impact rod 7 strikes the inner filter screen 2, it generates an instantaneous impact force and vibration, causing the broken shells originally attached to the inner filter screen 2 to be loosened and detached from the mesh, thereby effectively preventing the mesh from becoming clogged.

[0028] Meanwhile, in the early stages of clogging of the inner filter screen 2, only some small particles or impurities tend to accumulate in the mesh. The intermittent impact of the impact rod 7 can remove these initial blockages in time before they form a large area of ​​blockage, thus preventing the blockage from worsening.

[0029] The side walls of the housing 1 are symmetrically and horizontally fixed with crossbars 20, and two mounting plates 8 are slidably sleeved on the two crossbars 20 respectively.

[0030] Mounting plate 8 can only move horizontally on crossbar 20 to prevent sliding bar 6 from rotating, which would cause the position of inclined plate 10 to change and no longer be located on the moving path of abutment bar 13.

[0031] In this invention, when the rotating rod 3 and the stirring blade 4 are rotating, the reciprocating screw 5 will also rotate. The sliding plate 12, which is threaded onto the reciprocating screw 5, will move laterally back and forth with the two abutment rods 13. During the movement, the abutment rods 13 will intermittently abut against the inclined plate 10. Then, with the cooperation of the telescopic component and the elastic component, the two impact rods 7 will intermittently collide with the surface of the filter inner mesh cover 2, thereby causing the broken shells accumulated in the mesh of the filter inner mesh cover 2 to be vibrated and loosened, which can effectively prevent the mesh from being blocked.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
