[0002] Rice processing is a complex process aimed at separating the endosperm from the husk, bran, and embryo in rice grains to produce rice with better eating quality. This process can be divided into several main steps, including cleaning, hulling, and milling.

[0003] However, after the initial milling of rice, some dust remains on the outside of the rice grains. This dust mixes with the rice husks and grains, and when workers subsequently sieve and bag the rice husks and grains, this dust is shaken up, which adversely affects the workers' breathing. Therefore, this does not meet the current needs. To address this, we have proposed a convenient dust removal device for rice processing. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient dust removal device for rice processing, in order to solve the problem mentioned in the background art that after the initial rice milling, some dust exists on the outside of the rice and mixes with the rice husk and grains. When workers subsequently screen and bag the rice husks and grains, this dust is shaken up and has an adverse effect on the breathing of the workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient dust removal device for rice processing, comprising a bottom support:

[0006] A fixed bracket is fixedly installed on both sides of the upper surface of the bottom bracket. A feeding pipe is installed on one side of the upper end of the bottom bracket, and a rice grain discharge guide plate is installed on the other side above the bottom bracket. A fixed mounting rod is fixedly installed at the upper end of the feeding pipe, and a blocking plate is fixedly installed at one end of the fixed mounting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a coarse-mesh screen to intercept rice husks. Since the volume of rice husks is larger than that of rice grains and dust, the coarse-mesh screen can sieve the rice husks while rotating. A fine-mesh screen can intercept rice grains, allowing dust to pass through and move, thus enabling the device to sieve the rice grains and separate the dust from the rice grains. A dust collection cylinder can collect the dust. Because the inside of the dust collection cylinder is relatively smooth, the dust can gradually slide into the upper part of the dust removal net and then pass through the dust removal net into the dust collection box, thus achieving the purpose of dust removal. The device can sieve rice grains while removing dust, making the sieving and dust removal of rice grains simultaneous, which greatly improves production efficiency and avoids dust being stirred up by workers when bagging rice grains later, ensuring the health of workers.

[0016] 2. By installing rice grain discharge guide plates and rice husk discharge guide plates, the different lengths of the two plates facilitate the device to guide rice husks and rice grains into different compartments inside the collection box, achieving separate collection of rice husks and rice grains, enhancing the practicality of the device, giving it screening capabilities, and enriching its functions. The installation of drive rubber rollers can drive the dust collection cylinder to rotate, thereby causing the crushed rice entering the device to tumble inside the dust collection cylinder, separating the dust in the rice from the rice grains, facilitating the device to quickly remove dust from the rice grains.

[0022] 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.

[0023] Please see Figure 1-4 One embodiment of this utility model is a portable dust removal device for rice processing, comprising a bottom support 1.

[0024] Fixed bracket 2 is fixedly installed on both sides of the upper end face of bottom bracket 1. A feeding pipe 5 is installed on one side of the upper end of bottom bracket 1, and a rice grain discharge guide plate 15 is installed on the other side above bottom bracket 1. The different lengths of the rice grain discharge guide plate 15 and the rice husk discharge guide plate 16 facilitate the device in guiding rice husks and rice grains into different compartments inside the collection box 17, achieving separate collection of rice husks and rice grains, enhancing the practicality of the device, giving it screening capabilities, and enriching its functions. A fixed mounting rod is fixedly installed at the upper end of the feeding pipe 5. 10. A blocking plate 9 is fixedly installed at one end of the fixed mounting rod 10. A rice husk discharge guide plate 16 is provided above the rice grain discharge guide plate 15. A drive bracket 11 is fixedly installed on the outside of the fixed mounting rod 10. A drive rubber roller 12 is rotatably installed on the side of the drive bracket 11 near the rice husk discharge guide plate 16. The installation of the drive rubber roller 12 can drive the dust collection cylinder 7 to rotate, so that the crushed rice entering the device can roll inside the dust collection cylinder 7, so that the dust in the rice is separated from the rice, making it easier for the device to quickly remove the dust from the rice.

[0025] A support bracket 6 is fixed to the upper end of the bottom support bracket 1. A dust collection cylinder 7 is installed at the upper end of the support bracket 6, and the dust collection cylinder 7 is rotatably connected to the support bracket 6. The dust collection cylinder 7 has a fine-mesh screen 18 inside, and a coarse-mesh screen 19 inside the fine-mesh screen 18. The coarse-mesh screen 19 can intercept rice husks. Since the volume of rice husks is larger than rice grains and dust, the coarse-mesh screen 19 can sieve the rice husks during rotation. The fine-mesh screen 18 can intercept rice grains, allowing dust to pass through the fine-mesh screen 18 and move, thus enabling the device to sieve the rice grains and separate the dust from the rice grains. The dust collection cylinder 7 can collect dust. Because the inside of the dust collection cylinder 7 is relatively smooth, the dust can be gradually collected. The dust gradually slides into the upper part of the dust removal net 20, allowing the dust to pass through the dust removal net 20 and be discharged into the dust collection box 8, thereby achieving the purpose of dust removal by the device. This allows the device to screen the rice during the dust removal process, making the rice screening and dust removal proceed simultaneously, greatly improving production efficiency. At the same time, it prevents dust from being stirred up when workers bag the rice grains later, ensuring the health of the workers. The fine-mesh cylinder 18 is fixedly connected to the dust collection cylinder 7 and the coarse-mesh cylinder 19 by connecting rods 21. The coarse-mesh cylinder 19 is rotatably connected to the feeding pipe 5 by bearings. The dust removal net 20 is fixedly installed on the side of the dust collection cylinder 7 near the rice husk discharge guide plate 16, and the dust collection box 8 is set on the outside of the dust removal net 20.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A mounting bracket 3 is installed on one side of the fixed bracket 2, and the mounting bracket 3 is welded to the fixed bracket 2. An air intake fan 4 is installed on the upper end of the mounting bracket 3. The air intake fan 4 can introduce some low-intensity airflow into the device to assist the movement of the rice grains, thereby improving the separation efficiency of rice husks and rice grains. The output end of the air intake fan 4 is connected to the feeding pipe 5 through a pipe. An air outlet filter 14 is installed on the upper end of one side of the blockage plate 9, and the air outlet filter 14 is welded to the blockage plate 9. A rice husk discharge guide plate 16 is welded to the blockage plate 9. A caster wheel 22 is installed on the lower end of the bottom bracket 1. The caster wheel 22 can increase the efficiency of the device. The device is easy to install, allowing for quick movement and installation, making it more flexible. The casters 22 are connected to the bottom bracket 1 by screws. The dust collection box 8 is rotatably connected to the dust collection cylinder 7. The rice grain discharge guide plate 15 is welded to the fixed bracket 2. The filling pipe 5 is welded to the fixed bracket 2. The blocking plate 9 is welded to the rice grain discharge guide plate 15. A drive motor 13 is installed on one side of the drive bracket 11. The drive motor 13 is connected to the drive bracket 11 by screws. The drive motor 13 is connected to the drive rubber roller 12 by a coupling. A collection box 17 is provided on the other side of the upper surface of the bottom bracket 1.

[0027] Working Principle: During use, the crushed paddy rice is added into the device through the feeding pipe 5. Then, the air intake fan 4 blows a weak airflow into the feeding pipe 5 at a low power setting. At the same time, the drive motor 13 drives the drive rubber roller 12 to rotate, which in turn drives the dust collection cylinder 7 to rotate. This causes the paddy rice to tumble inside the coarse-pore mesh cylinder 19. Under the combined action of tumbling and airflow, the rice grains and dust in the paddy rice pass through the coarse-pore mesh cylinder 19 and enter the fine-pore mesh cylinder 18, while the paddy husks, due to their larger size, remain inside the coarse-pore mesh cylinder 19. As the dust collection cylinder 7 continues to rotate, the dust mixed inside the rice grains in the fine-pore mesh cylinder 18 passes through the fine-pore mesh cylinder 18. The perforated mesh cylinder 18 enters the dust collection cylinder 7. Since the rice grains are larger than the mesh openings of the fine-perforated mesh cylinder 18, the dust separates from the rice grains. As the dust collection cylinder 7 continues to rotate, the dust moves along the smooth inner wall of the dust collection cylinder 7 to the upper end of the dust discharge screen 20. Then, the dust passes through the dust discharge screen 20 and enters the dust collection box 8. Meanwhile, the rice grains and rice husks are discharged into different compartments inside the collection box 17 via the rice grain discharge guide plate 15 and the rice husk discharge guide plate 16, respectively. This allows the device to automatically sieve the rice during the dust removal process. The different lengths of the rice grain discharge guide plate 15 and the rice husk discharge guide plate 16 facilitate the guidance of rice husks and rice grains into the dust collection box 8. The different compartments inside the collection box 17 allow for the separate collection of rice husks and grains, enhancing the practicality of the device and giving it screening capabilities, thus enriching its functions. The installation of the drive rubber roller 12 drives the dust collection cylinder 7 to rotate, causing the crushed rice entering the device to tumble inside the dust collection cylinder 7, separating the dust from the rice grains and facilitating rapid dust removal. The installation of the coarse-mesh screen 19 intercepts the rice husks; since the rice husks are larger than the grains and dust, the coarse-mesh screen 19 can screen the rice husks during rotation. The installation of the fine-mesh screen 18 allows for the screening of the rice grains. The interception process allows dust to move through the fine mesh cylinder 18, enabling the device to sieve the rice grains and separate the dust from the rice. The dust collection cylinder 7 collects the dust. Because the inside of the dust collection cylinder 7 is relatively smooth, the dust gradually slides into the upper part of the dust discharge net 20, and then passes through the dust discharge net 20 into the dust collection box 8, thus achieving the purpose of dust removal. The device can sieve the rice while removing dust, making the sieving and dust removal of rice simultaneous, which greatly improves production efficiency and prevents dust from being stirred up when workers bag the rice grains later, ensuring the health of the workers.
