Description

Technical Field

[0001] This utility model relates to the field of rice destoner technology, and more particularly to a rice gravity destoner device. Background Technology

[0002] The rice gravity separation device is a highly efficient cleaning equipment primarily used to remove heavy impurities such as stones and glass from rice, ensuring rice quality and food safety. Based on the principle of gravity separation, the device separates rice from impurities such as stones through the synergistic action of airflow and a vibrating screen. During operation, the material enters the vibrating screen through the feed inlet. Under the action of airflow generated by the fan, lighter rice particles are suspended and flow forward, while heavier impurities such as stones sink to the bottom of the screen and are discharged through different outlets. The device employs an adjustable airflow control system, adaptable to different varieties and moisture contents of rice, ensuring stable sorting results. Its compact structure and simple operation make it suitable for rice processing plants, grain storage facilities, and other similar locations.

[0003] The existing rice gravity destoning device has a dust cover on top, with the feed inlet and dust suction outlet located on top of the dust cover. The bottom of the dust cover is fixed to the top of the destoning mechanism by a ring of bolts. Disassembling and assembling the dust cover every time the screen of the destoning mechanism is cleaned is very time-consuming, thus affecting the maintenance efficiency of the device. Therefore, further improvement is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rice specific gravity destone removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rice specific gravity destone removal device, comprising a base, a destone removal mechanism, and a top cover. A bracket is fixedly installed between the destone removal mechanism and the base. The top cover is located on top of the destone removal mechanism. An inlet and a dust suction port are provided at the top of the top cover. A horizontal plate is fixedly connected to the inlet and the dust suction port. A support plate is fixed to the lower surface of the horizontal plate. Telescopic support components are fixed to both ends of the lower surface of the support plate. T-shaped guide rails are fixed to both sides of the base near the two telescopic support components. A C-shaped slide is slidably connected to the surface of each T-shaped guide rail. An L-shaped rod is fixed to the surface of each of the two C-shaped slides. The bottom ends of the two telescopic support components are fixedly connected to the two L-shaped rods respectively.

[0006] Furthermore, a rubber pad is fixed to the bottom of the top cover, and the rubber pad is in contact with the upper surface of the stone removal mechanism.

[0007] Furthermore, the top cover sidewall is provided with multiple viewing windows.

[0008] Furthermore, the telescopic support assembly includes a square tube fixed to the lower surface of the support plate, and a square rod is slidably connected inside the square tube. The bottom end of the square rod is fixed to the upper surface of the L-shaped rod. A first fastening bolt is threadedly connected to the bottom side wall of the square tube and rotated through it. The end of the first fastening bolt located inside the square tube is in contact with the surface of the square rod.

[0009] Furthermore, the C-shaped slide sidewall is connected to a second fastening bolt through and via a threaded connection, with one end of the second fastening bolt inside the C-shaped slide fitting against the surface of the T-shaped guide rail.

[0010] Furthermore, end plates are fixed at both ends of the T-shaped guide rail.

[0011] Furthermore, the inner top wall of the C-shaped slide is provided with multiple grooves, and each groove is rotatably connected to a roller, the bottom end of which is in contact with the upper surface of the T-shaped guide rail.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model rice destone removal device includes a base, a destone removal mechanism, a top cover, a support plate, a telescopic support assembly, a T-shaped guide rail, a C-shaped slide, and an L-shaped rod. The top cover is supported by the telescopic support assembly. When it is necessary to clean the screen of the destone removal mechanism, the telescopic support assembly is adjusted to extend so that the top cover rises from the top of the destone removal mechanism. Then, the C-shaped slide is moved along the T-shaped guide rail so that the top cover moves away from the destone removal mechanism. At this time, the screen of the destone removal mechanism can be cleaned, which solves the problem of complicated top cover disassembly.

[0014] 2. When in use, this utility model rice destone removal device is equipped with a T-shaped guide rail and a C-shaped slide. Rollers are installed on the inner top wall of the C-shaped slide. When the C-shaped slide slides along the surface of the T-shaped guide rail, the rollers can reduce the friction, making the C-shaped slide move more smoothly. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a rice destone removal device is disclosed, comprising a base 1, a destone removal mechanism 3, and a top cover 4. A bracket 2 is fixedly installed between the destone removal mechanism 3 and the base 1. The top cover 4 is located on top of the destone removal mechanism 3. A feed inlet 5 and a dust suction port 6 are provided at the top of the top cover 4. A horizontal plate 7 is fixedly connected to the feed inlet 5 and the dust suction port 6. A support plate 8 is fixed to the lower surface of the horizontal plate 7. Telescopic support components 9 are fixed to both ends of the lower surface of the support plate 8. T-shaped guide rails 10 are fixed to both sides of the base 1 near the two telescopic support components 9. A C-shaped slide block 11 is slidably connected to the surface of each T-shaped guide rail 10. An L-shaped rod 12 is fixed to the surface of each of the two C-shaped slide blocks 11. The bottom ends of the two telescopic support components 9 are fixedly connected to the two L-shaped rods 12 respectively.

[0023] In this embodiment, the suction port 6 is connected to the suction mechanism, and the stone removal mechanism 3 is the same as the prior art. Its working principle and specific structure will not be described in detail.

[0024] A rubber pad is fixed to the bottom of the top cover 4, and the rubber pad is in contact with the upper surface of the stone removal mechanism 3.

[0025] In this embodiment, the top cover 4 and the stone removal mechanism 3 are not fixedly connected by bolts, and the rubber gasket can increase the sealing between the top cover 4 and the stone removal mechanism 3, preventing dust inside the device from overflowing from the gap between the top cover 4 and the stone removal mechanism 3.

[0026] The top cover has multiple viewing windows on its four side walls.

[0027] The viewing window allows for easy observation of the degree of clogging inside the screen of the destone mechanism 3, thereby determining whether the screen inside the destone mechanism 3 needs to be cleaned.

[0028] The telescopic support assembly 9 includes a square tube 91 fixed to the lower surface of the support plate 8, and a square rod 92 is slidably connected inside the square tube 91. The bottom end of the square rod 92 is fixed to the upper surface of the L-shaped rod 12. A first fastening bolt 93 is threadedly connected to the bottom side wall of the square tube 91 and rotated through it. One end of the first fastening bolt 93 located inside the square tube 91 is in contact with the surface of the square rod 92.

[0029] In this embodiment, the square tube 91 can slide up and down along the square rod 92. When the square tube 91 moves upward, it can drive the support plate 8 to rise, thereby driving the horizontal plate 7, the feed inlet 5, and the top cover 4 to rise, so that the top cover 4 can be quickly separated from the destoning mechanism 3. When the square tube 91 moves downward, it drives the horizontal plate 7, the feed inlet 5, and the top cover 4 to fall, so that the top cover 4 can be placed back on top of the destoning mechanism 3, simplifying the disassembly and assembly steps of the top cover 4. After each adjustment of the position of the square tube 91, tightening the first fastening bolt 93 presses against the square rod 92 to fix the square tube 91.

[0030] The C-shaped slide 11 has a second fastening bolt 13 that runs through its side wall and is connected by a threaded rotation. One end of the second fastening bolt 13 inside the C-shaped slide 11 is in contact with the surface of the T-shaped guide rail 10.

[0031] The C-shaped slide 11 can slide along the surface of the T-shaped guide rail 10, thereby driving the L-shaped rod 12 to move laterally. The L-shaped rod 12 then drives the telescopic support assembly 9 to move laterally, thus realizing the lateral movement of the top cover 4. After adjusting the position of the C-shaped slide 11, tighten the second fastening bolt 13 to press against the surface of the T-shaped guide rail 10, thereby fixing the C-shaped slide 11.

[0032] Both ends of the T-shaped guide rail 10 are fixed with end plates 14.

[0033] By fixing end plates 14 at both ends of the T-shaped guide rail 10, the C-shaped slide 11 is prevented from detaching from the T-shaped guide rail 10 when it slides along the surface of the T-shaped guide rail 10.

[0034] The inner top wall of the C-shaped slide 11 has multiple grooves, and each groove is rotatably connected to a roller 15. The bottom end of the roller 15 is in contact with the upper surface of the T-shaped guide rail 10.

[0035] After the roller 15 is installed, the roller 15 can reduce the friction of the C-shaped slide 11 sliding along the T-shaped guide rail 10.

[0036] Working Principle: When using this device, rice is added to the destoning mechanism 3 through the feed inlet 5. The destoning mechanism 3 then screens and removes stones from the rice. Dust generated during the destoning process is drawn away by the suction mechanism through the suction port 6. When the screen of the destoning mechanism 3 needs cleaning, observe through the viewing window on the top cover 4. First, adjust the telescopic support assembly 9 to extend, causing the top cover 4 to rise from the top of the destoning mechanism 3. Then, move the C-shaped slide 11 along the T-shaped guide rail 10, thereby moving the top cover 4 away from the destoning mechanism 3. Once the top cover 4 has moved away from the top of the destoning mechanism 3, the screen inside can be cleaned. After cleaning, move the top cover 4 back above the destoning mechanism 3, then adjust the telescopic support assembly 9 to shorten, and finally, replace the top cover 4 on top of the destoning mechanism 3.
