Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically a rice polishing machine. Background Technology
[0002] With global population growth and rising living standards, the demand for high-quality rice is increasing. Consumers are no longer satisfied with simply hulling paddy into brown rice and then processing it into white rice; they expect rice to have better appearance, taste, and a longer shelf life. Rice polishing, a key step in the rice processing, has emerged to address this need. It removes residual bran, chaff, and other impurities from the surface of the rice grains, making them smoother and improving the overall quality of the rice to meet the market's demand for premium rice.
[0003] Existing rice polishing machines have the following drawbacks:
[0004] Rice polishing machines need to sieve rice before polishing it, but existing technology often causes sieve holes to become clogged during the sieving process.
[0005] Before rice enters the polishing machine, it cannot be guaranteed to be thoroughly cleaned, and dirt such as dust and bran powder attached to the surface of the rice grains cannot be removed. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a rice polishing machine that can avoid sieve hole clogging and has a cleaning function.
[0007] To solve the above problems, the technical solution of this utility model is as follows: a rice polishing machine, including a workbench and a polishing machine body, two support frames are fixedly connected to the upper side of the workbench, a vibrating screen mechanism is provided at the top of the two support frames, two symmetrical cleaning mechanisms are provided on the upper side of the workbench, and a feed hopper is connected to the top of the polishing machine body; the vibrating screen mechanism includes four mounting seats, the four mounting seats are respectively bolted to the top ends of the two support frames, springs are fixedly connected to the upper side of the four mounting seats, and dampers are connected to the inner side of each of the four springs.
[0008] Furthermore, a top plate is fixedly connected to the top of each of the four springs, and a screening frame is fixedly connected to the upper side of the top plate. A cavity is opened inside the screening frame, and a number of sieve holes are opened on the screening frame.
[0009] Furthermore, a motor base is fixedly connected to the lower side of the screening frame, and a vibration motor is connected to one side of the motor base.
[0010] Furthermore, the cleaning mechanism includes a water tank, which is fixedly connected to the upper side of the workbench. A water pipe is connected to the top of the water tank, and a main flow pipe is connected to the end of the water pipe. The main flow pipe is fixedly connected to one side of the inner wall of the screening frame. A water pump is connected to the outer side of the water pipe, and several rotating spray heads are connected to one side of the main flow pipe.
[0011] Furthermore, a waste discharge port is connected to one side of the screening frame, and the waste discharge port is located outside the cavity.
[0012] Furthermore, a guide plate is fixedly connected to the end of the screening frame, and the guide plate is located on the upper side of the feed hopper.
[0013] The advantages of this invention compared to existing technologies are as follows:
[0014] This invention features a vibrating sieving mechanism. A vibrating motor drives the sieving frame to vibrate, and with a rationally designed sieve aperture, it efficiently removes impurities and substandard particles from the rice, ensuring uniform quality of the rice before polishing. The vibration frequency can be adjusted via the vibrating motor to meet different precision sieving requirements. A combination of springs and dampers on the mounting base provides cushioning for the sieving frame. During the vibrating sieving process, this prevents the rice from breaking due to violent impacts on equipment components, reducing processing losses and maintaining the integrity of the rice grains.
[0015] This invention features a cleaning mechanism. A rotating spray head draws water from a water tank using a water pump, which then delivers the water through pipes and a main pipe, achieving multi-angle, all-around spray cleaning of the rice. The water flow removes dust, bran, and other dirt adhering to the surface of the rice grains, improving the cleanliness of the rice. Attached Figure Description

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0024] like Figures 1 to 4 As shown, a rice polishing machine includes a worktable 1 and a polishing machine body 5. Two support frames 2 are fixedly connected to the upper side of the worktable 1, and a vibrating screen mechanism 3 is provided at the top of the two support frames 2. Two symmetrical cleaning mechanisms 4 are provided on the upper side of the worktable 1. A feed hopper 6 is connected to the top of the polishing machine body 5. A waste residue outlet 310 is connected to one side of the screening frame 305, and the waste residue outlet 310 is located outside the cavity 306. A guide plate 7 is fixedly connected to the end of the screening frame 305, and the guide plate 7 is located above the feed hopper 6.
[0025] The vibrating sieve mechanism 3 includes four mounting bases 301, which are bolted to the top ends of the two support frames 2. Springs 302 are fixedly connected to the upper sides of each of the four mounting bases 301, and dampers 303 are connected to the inner sides of each spring 302. A top plate 304 is fixedly connected to the top of each spring 302, and a sieve frame 305 is fixedly connected to the upper side of the top plate 304. A cavity 306 is formed inside the sieve frame 305, and several sieve holes 307 are formed on the sieve frame 305. A motor base 308 is fixedly connected to the lower side of the sieve frame 305, and a vibrating motor 309 is connected to one side of the motor base 308. The vibrating motor 309 drives the sieve frame 305 to vibrate, and with the rationally designed sieve holes 307, it can efficiently remove impurities and unqualified particles from the rice, ensuring uniform quality of the rice entering the polishing stage. The vibration frequency can be adjusted by the vibrating motor 309 to meet different precision screening requirements. The spring 302 on the mounting base, combined with the damper 303, provides cushioning for the screening frame 305. During the vibratory screening process, this prevents the rice from breaking due to violent impacts on the equipment components, reducing processing losses and maintaining the integrity of the rice grains.
[0026] The cleaning mechanism 4 includes a water tank 401, which is fixedly connected to the upper side of the workbench 1. A water pipe 402 is connected to the top of the water tank 401, and a main flow pipe 403 is connected to the end of the water pipe 402. The main flow pipe 403 is fixedly connected to one side of the inner wall of the screening frame 305. A water pump 405 is connected to the outside of the water pipe 402, and several rotary spray heads 404 are connected to one side of the main flow pipe 403. The rotary spray heads 404 draw water from the water tank with the help of the water pump 405, and after being transported through the water pipe 402 and the main flow pipe 403, they achieve multi-angle, all-round spray cleaning of the rice. The water flow can remove dust, bran powder, and other dirt adhering to the surface of the rice grains, improving the cleanliness of the rice.
[0027] In practical use, rice is placed on top of the screening rack 305. The vibration motor 309 drives the screening rack 305 to vibrate. Combined with the rationally designed sieve holes 307, this efficiently removes impurities and substandard particles from the rice, ensuring uniform quality of the rice entering the polishing stage. The spring 302 and damper 303 on the mounting base provide cushioning for the screening rack 305. Simultaneously, the water pump 405 draws water from the water tank 401 into the main flow pipe 403 through the water pipe 402. Several rotating spray heads 404 rinse the rice, and the rinsed rice falls into the polishing machine body 5 through the guide plate 7 for polishing. Dirt flows out through the cavity 306 and the waste discharge port 310.
