Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a rice processing device for removing broken rice. Background Technology

[0002] During rice processing, rice grains that are not plump enough or have low strength are easily broken, resulting in broken rice. Because of their small size and light weight, broken rice is often mixed with rice bran and rice bran husks during processing.

[0003] Chinese Patent Publication No. CN212143406U discloses a broken rice processing device for rice processing, including a base, a shell welded to the top of the base, a feed hopper welded to one end of the top of the shell, a flow-limiting plate welded to the bottom of the feed hopper, and a top cover hinged to the inner wall of the top opening of the shell. A first filter screen is installed inside the shell along an inclined direction below the feed hopper, with both sides of the first filter screen welded to the inner wall of the shell. A first discharge port is opened on the inner wall of the shell near the bottom of the first filter screen. A second filter screen is welded along an inclined direction to the inner wall of the bottom of the shell, located below the first filter screen. Both the first and second filter screens are fixedly connected with equally spaced baffles. This utility model can fully separate mixtures, improving separation efficiency; the top cover can be directly opened for maintenance or cleaning of the equipment's interior, simplifying the later maintenance process and avoiding unnecessary waste of manpower and time.

[0004] While existing technologies can filter out rice bran and rice bran husks mixed in with broken rice through the first and second filters, the limited processing capacity of each filter surface means it cannot handle large amounts of material. When encountering a large amount of material, blockage may occur, leading to a reduction in the screening effect. Utility Model Content

[0005] The purpose of this invention is to provide a rice processing device for handling broken rice, which solves the problem in the prior art that blockage may occur when encountering a large amount of material, leading to a reduction in screening efficiency.

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

[0007] A rice processing device for handling broken rice includes a processing chamber. Support rods are symmetrically distributed and fixedly installed on the upper surface of the processing chamber. A screening assembly is arranged between the support rods. The screening assembly includes a sieve plate, a support frame, a vibrating motor, a funnel, a guide pipe, a corrugated pipe, a discharge pipe, and a fan. The sieve plate is movably installed between the support rods. The support frame is fixedly connected to the top of the sieve plate. The vibrating motor is fixedly installed on the top of the sieve plate. The funnel is fixedly installed at the bottom of the sieve plate. The guide pipe is fixedly connected to the bottom of the funnel. The corrugated pipe is fixedly connected to the side surface of the guide pipe. The discharge pipe is fixedly connected to the right side of the processing chamber. The fan is fixedly installed inside the discharge pipe.

[0008] Preferably, the discharge pipe is connected to the corrugated pipe, the front end of the processing box is provided with a slag discharge port, the bottom of the processing box is provided with a discharge port, and the top of the processing box is fixedly connected to an inlet pipe.

[0009] Preferably, the support rod has an internal buffer structure, which includes a movable slide groove, a limiting slide groove, a movable slider, a limiting slider, and a helical spring. The movable slide groove is formed on the side surface of the support rod, and the limiting slide groove is formed on the inner wall of the movable slide groove.

[0010] Preferably, the movable slider is slidably connected inside the movable groove, the limiting slider is fixedly connected to the side of the movable slider, and the helical spring is fixedly connected to the top of the movable slider.

[0011] Preferably, the limiting slider is adapted to the limiting groove, the top of the helical spring is fixedly connected to the upper surface of the movable groove, and the movable slider is fixedly connected to the sieve plate.

[0012] Preferably, a control panel is fixedly installed on the left side of the processing box, a support column is fixedly installed on the bottom of the processing box, and an anti-slip pad is fixedly installed on the bottom of the support column.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses a sieve plate to initially screen broken rice, and then uses a fan to perform a secondary air separation on the screened broken rice. This not only improves the screening quality of broken rice, but also effectively avoids the problem of reduced screening efficiency caused by a large amount of material at one time.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5A rice processing device for breaking rice includes a processing box 1. Support rods 2 are symmetrically distributed and fixedly installed on the upper surface of the processing box 1. A screening assembly 3 is arranged between the support rods 2. The screening assembly 3 includes a sieve plate 301, a support frame 302, a vibrating motor 303, a funnel 304, a guide pipe 305, a corrugated pipe 306, a discharge pipe 307, and a fan 308. The sieve plate 301 is movably installed between the support rods 2. The support frame 302 is fixedly connected to the top of the sieve plate 301. The vibrating motor 303 is fixedly installed on the top of the sieve plate 301. The funnel 304 is fixedly installed on the bottom of the sieve plate 301. The guide pipe 305 is fixedly connected to the bottom of the funnel 304. The corrugated pipe 306 is fixedly connected to the side surface of the guide pipe 305. The discharge pipe 307 is fixedly connected to the right side of the processing box 1. The fan 308 is fixedly installed inside the discharge pipe 307.

[0025] The discharge pipe 307 is connected to the corrugated pipe 306. The front end of the processing box 1 is provided with a slag discharge port 4, the bottom of the processing box 1 is provided with a discharge port 6, and the top of the processing box 1 is fixedly connected with a feed pipe 5.

[0026] The sieve plate 301 has internal sieve holes to remove broken rice, rice bran, and rice bran husks. The screening assembly 3 is configured such that broken rice mixed with rice bran and husks falls onto the sieve plate 301 through the feed pipe 5. Then, the vibration motor 303 is activated, causing the sieve plate 301 to vibrate. During this vibration, the broken rice and rice bran fall into the funnel 304, while the rice bran husks are removed by the vibration of the sieve plate 301. The rice and rice bran that fall into the funnel 304 are discharged from the slag discharge port 4. Due to gravity, they fall into the feed pipe 305. At the same time, the fan 308 is activated, which draws air from the feed pipe 305, thereby separating the rice bran from the rice. The rice bran is then discharged to the outside through the corrugated pipe 306 and the discharge pipe 307. The rice, being heavier, is not attracted by the fan 308 and is discharged from the discharge port 6 through the bottom of the feed pipe 305. This invention uses the sieve plate 301 to initially screen the rice, and then uses the fan 308 to perform a secondary air separation on the screened rice. This not only improves the screening quality of the rice but also effectively avoids the problem of reduced screening efficiency caused by a large amount of material at one time.

[0027] Furthermore, the support rod 2 is provided with a buffer structure inside. The buffer structure includes a movable slide 201, a limiting slide 202, a movable slider 203, a limiting slider 204 and a coil spring 205. The movable slide 201 is opened on the side surface of the support rod 2, and the limiting slide 202 is opened on the inner wall of the movable slide 201.

[0028] The movable slider 203 is slidably connected inside the movable slide groove 201, the limiting slider 204 is fixedly connected to the side of the movable slider 203, and the helical spring 205 is fixedly connected to the top of the movable slider 203; the limiting slider 204 is adapted to the limiting slide groove 202, the top end of the helical spring 205 is fixedly connected to the upper surface of the movable slide groove 201, and the movable slider 203 is fixedly connected to the sieve plate 301.

[0029] During the vibration of the sieve plate 301, the sieve plate 301 will synchronously drive the movable slider 203 to slide up and down inside the movable slide groove 201. During the sliding process, the movable slider 203 can be buffered by the elastic force of the helical spring 205, thus extending the service life of the sieve plate 301.

[0030] Furthermore, a control panel 7 is fixedly installed on the left side of the processing box 1, a support column 8 is fixedly installed on the bottom of the processing box 1, and an anti-slip pad 9 is fixedly installed on the bottom of the support column 8.

[0031] The installation of the anti-slip mat 9 increases friction with the placement surface, improving the safety and stability of the device.

[0032] In summary:

[0033] When using the device, first place it on a flat surface, then place the three containers at the bottom of the slag discharge port 4, the feed pipe 5, and the discharge port 6 respectively, so that the items discharged from the three locations can be collected.

[0034] Then, the broken rice mixed with rice bran and rice bran husks can be fed through the feed pipe 5, causing the broken rice to fall onto the screen plate 301. Then, the vibration motor 303 is started, causing the screen plate 301 to vibrate. During the vibration of the screen plate 301, the broken rice and rice bran will fall into the funnel 304. The rice bran husks will be discharged from the slag discharge port 4 due to the vibration of the screen plate 301. The broken rice and rice bran that fall into the funnel 304 will fall into the guide pipe 305 due to gravity. At the same time, the fan 308 is started, causing the fan 308 to draw air from the guide pipe 305, thereby causing the rice bran to separate from the broken rice. Then, it is discharged to the outside through the corrugated pipe 306 and the discharge pipe 307. The broken rice, because of its own weight, will not be attracted by the fan 308, and will be discharged from the discharge port 6 through the bottom of the guide pipe 305.

[0035] During the vibration of the sieve plate 301, the sieve plate 301 will simultaneously drive the movable slider 203 to slide up and down inside the movable slide groove 201. During the sliding process, the movable slider 203 can be buffered by the elastic force of the helical spring 205.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
