Description

Technical Field

[0001] This application relates to the technical field of rice hulling machines, and particularly relates to a rice hulling machine for rice production and processing. Background Art

[0002] A rice hulling machine is a grain processing machine that removes the glumes of paddy rice to produce brown rice. It can remove the outer shell of paddy rice, reduce the breakage of rice grains and damage to the epidermis, and keep the brown rice as intact as possible. After retrieval, the patent document with the authorization announcement number CN219232455U discloses a rice hulling machine for rice production and processing, including a box body. A rotating shaft is rotatably arranged in the box body, a first rubber roll is fixedly arranged on the outer surface of the rotating shaft, a rotating rod is rotatably arranged in the box body, a second rubber roll is fixedly arranged on the outer surface of the rotating rod, a sleeve is fixedly arranged in the box body, a plug rod is movably arranged in the sleeve, a collection box is fixedly arranged on the plug rod, and second motors are fixedly arranged on both sides of the collection box. When the rice and rice husks after hulling fall onto the second filter screen, the second motors are vibration motors. By turning on the second motors, the rice leaks out from the discharge hopper, and the rice husks on the second filter screen are processed by opening the box door. The collection box can be vibrated through the vibration springs, so that the rice and rice husks can be separated, which not only saves a lot of time but also saves manpower.

Specific embodiments

[0025] Next, the technical solutions of the present application will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0026] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a rice huller for rice production and processing, including the main body 1 of the rice huller and the feed hopper 2 fixedly installed on the top of the main body 1 of the rice huller. The feed hopper 2 is connected to the inside of the main body 1 of the rice huller. It should be noted that the main body 1 of the rice huller is a rice huller for rice production and processing disclosed in the patent document with the authorization announcement number CN219232455U, and its internal structure composition and working principle have been publicly described, so no further description will be made herein. Among them:

[0027] On the main body 1 of the rice huller, there is a feeding mechanism for lifting and conveying paddy to the feeding hopper 2. The feeding mechanism includes a cylinder cover 3, a lifting and feeding assembly, a dust removal assembly, and a material poking and anti-blocking assembly. The bottom of the cylinder cover 3 is of an open structure, and the cylinder cover 3 is fixedly connected to the top of the feeding hopper 2. The lifting and feeding is arranged on the right side of the cylinder cover 3. The lifting and feeding assembly is used to lift and convey paddy from a low position to a high position inside the cylinder cover 3, which can replace the existing method of manually carrying paddy above the main body 1 of the rice huller and then pouring the paddy into the main body 1 of the rice huller, saving the physical consumption of workers. The lifting and feeding assembly includes a feeding cylinder 4, a motor 5, a spiral feeding shaft 6, a feeding hopper 7, and a discharging pipe 8. The feeding cylinder 4 is fixedly installed on the right side wall of the main body 1 of the rice huller and is inclined. The motor 5 is fixedly installed at the bottom end of the feeding cylinder 4. The spiral feeding shaft 6 is rotatably installed inside the feeding cylinder 4. The output shaft end of the motor 5 is fixedly connected to the bottom end of the spiral feeding shaft 6. The feeding hopper 7 is fixedly connected to the right bottom of the feeding cylinder 4. The discharging pipe 8 is fixedly connected to the left top of the feeding cylinder 4 and is inclined. One end of the discharging pipe 8 extends into the cylinder cover 3. The setting of the feeding hopper 7 facilitates pouring paddy into the feeding cylinder 4. By using the motor 5, the rotation of the spiral feeding shaft 6 can be controlled. By the rotation of the spiral feeding shaft 6, paddy can be uniformly conveyed along the inclined direction of the feeding cylinder 4, so that the paddy enters the cylinder cover 3 uniformly and at a constant speed through the discharging pipe 8, achieving the effect of automatic lifting and feeding. The dust removal assembly is arranged on the left side of the cylinder cover 3. The dust removal assembly is used to suck away the dust mixed in the paddy during the feeding process, achieving the effect of dust removal, and thus can ensure the quality of the subsequent dehulling of paddy to make brown rice. The dust removal assembly includes a vacuum cleaner 9, a dust suction pipe 10, a baffle net 11, a dust discharging pipe 12, and a dust collection cloth bag 13. The vacuum cleaner 9 is fixedly installed on the top of the main body 1 of the rice huller and is located on the left side of the cylinder cover 3. The dust suction pipe 10 is fixedly connected to the suction end of the vacuum cleaner 9. One end of the dust suction pipe 10 extends into the cylinder cover 3. The baffle net 11 is fixedly installed at one end of the dust suction pipe 10 located inside the cylinder cover 3. The dust discharging pipe 12 is fixedly connected to the discharging end of the vacuum cleaner 9. The dust collection cloth bag 13 is detachably installed and fixed at one end of the dust discharging pipe 12 through a binding rope. By the suction force generated when the vacuum cleaner 9 operates, the dust in the paddy can be sucked into the dust collection cloth bag 13 for storage. By using the baffle net 11, paddy can be prevented from being sucked into the dust suction pipe 10. It should be noted that the mesh size of the baffle net 11 is smaller than the particle size of the paddy. The dust collection cloth bag 13 is fixed by a binding rope to facilitate the disassembly and assembly of the dust collection cloth bag 13. The material poking and anti-blocking assembly is arranged inside the cylinder cover 3. The material poking and anti-blocking assembly is used to prevent paddy from blocking the feeding hopper 2 during the feeding process and ensure that paddy smoothly enters the main body 1 of the rice huller. The material poking and anti-blocking assembly includes an electric telescopic rod 14, a material poking rod 15, and a plurality of arc-shaped barbs 16. The electric telescopic rod 14 is fixedly installed on the top inner wall of the cylinder cover 3. The material poking rod 15 is fixedly installed at the output shaft end of the electric telescopic rod 14 and is located on the right side of the baffle net 11. The bottom end of the material poking rod 15 extends into the feeding hopper 2.A plurality of arc-shaped barbs 16 are fixedly installed on the material poking rod 15 and are evenly distributed. By utilizing the telescopic feature of the electric telescopic rod 14, the vertical lifting of the material poking rod 15 and the plurality of arc-shaped barbs 16 can be controlled, and thus the paddy can be poked into the rice hulling machine main body 1.

[0028] In this embodiment, the feed hopper 2 is in the shape of a frustum of a cone, and the inner diameter dimension of the feed hopper 2 decreases sequentially from top to bottom. The inner diameter dimension of the barrel cover 3 is the same as the maximum inner diameter dimension of the feed hopper 2, which can ensure that all the paddy entering the barrel cover 3 enters the feed hopper 2 and then falls into the rice hulling machine main body 1.

[0029] In this embodiment, in order to improve the stability of the material conveying cylinder 4, two reinforcing seats 19 are fixedly installed on the right outer wall of the rice hulling machine main body 1, and the material conveying cylinder 4 is fixedly installed on the two reinforcing seats 19.

[0030] In this embodiment, the diameter dimension of the material blocking net 11 is larger than the outer diameter dimension of the dust suction pipe 10.

[0031] In this embodiment, in order to stably support the dust collection cloth bag 13, a bearing plate 20 is fixedly installed on the left outer wall of the rice hulling machine main body 1, and the bottom of the dust collection cloth bag 13 is in contact with the top of the bearing plate 20.

[0032] In this embodiment, during the material poking process, in order to be able to scrape and clean the surface of the material blocking net 11, ensure the good air permeability of the material blocking net 11, and achieve the effect of effective dust removal, a cross bar 17 is fixedly installed on one side of the material poking rod 15, one end of the cross bar 17 is fixedly installed with a scraping blade 18, and the left side of the scraping blade 18 is in sliding contact with the right side wall of the material blocking net 11.

[0033] In this embodiment, in order to ensure that the scraping blade 18 can comprehensively scrape and clean the material blocking net 11, the width dimension of the scraping blade 18 is larger than the diameter dimension of the material blocking net 11.

[0034] In this embodiment, it should be supplemented that the motor 5, the vacuum cleaner 9 and the electric telescopic rod 14 can all be obtained by purchasing in the market. Their circuit connection methods and control methods belong to the mature technologies in this field, so no further elaboration will be made herein.

[0035] Through the above structure, when the rice hulling machine for rice production and processing provided by this application is in use, it can lift and convey paddy from a low position to the high barrel cover 3, which can replace the existing method of manually carrying paddy above the rice hulling machine main body 1 and then pouring the paddy into the rice hulling machine main body 1, saving the physical consumption of workers. And during the feeding process, it can suck away the dust mixed in the paddy, achieving the effect of effective dust removal, ensuring the quality of the subsequent dehulling of paddy into brown rice, and ensuring that the paddy can smoothly pass through the feed hopper 2 and enter the rice hulling machine main body 1 for shelling processing, without the phenomenon of blockage of the feed hopper 2;

[0036] When using the main body 1 of the rice huller to process paddy into brown rice by hulling, by controlling the operation of the motor 5, the motor 5 drives the spiral feeding shaft 6 to rotate, pours the paddy from the feeding hopper 7 into the feeding cylinder 4, and the spiral feeding shaft 6 can be used to convey the paddy, so that the paddy enters the cylinder cover 3 evenly in terms of speed and quantity through the feeding pipe 8. The paddy entering the cylinder cover 3 then falls into the interior of the main body 1 of the rice huller through the feeding hopper 2 for hulling processing, and thus the effect of automatic lifting and feeding can be achieved;

[0037] During the feeding process, by controlling the operation of the vacuum cleaner 9, using the suction force generated by the vacuum cleaner 9, the dust in the paddy can be sucked into the dust collection cloth bag 13. The baffle net 11 can be used to block and intercept the paddy to prevent the paddy from being sucked into the dust suction pipe 10, and thus the effect of dust removal can be achieved, which can ensure the quality of the subsequent hulling of paddy into brown rice;

[0038] During the feeding and dust removal processes, by controlling the electric telescopic rod 14 to perform reciprocating elongation operation and contraction reset, the poking rod 15 and multiple arc-shaped barbs 16 can be controlled to vertically lift and lower, and thus the paddy can be poked into the main body 1 of the rice huller to prevent the paddy from blocking the feeding hopper 2 and ensure that the paddy smoothly enters the main body 1 of the rice huller. And by using the poking rod 15 to drive the cross bar 17 and the scraping blade 18 to reciprocate up and down, the scraping blade 18 can be used to scrape and clean the surface of the baffle net 11, avoid the paddy being adsorbed on the surface of the baffle net 11 and blocking the mesh holes on the baffle net 11, ensure the good air permeability of the baffle net 11, and ensure the effective and smooth progress of dust removal;

[0039] After the work is completed, stop the operation of the motor 5, the vacuum cleaner 9 and the electric telescopic rod 14.
