Technical Field
[0001] This utility model relates to the field of dust removal technology in rice processing, specifically a dust collection and removal device for rice processing. Background Technology
[0002] Rice is a finished product made from paddy rice through processes such as cleaning, hulling, milling, and finishing. The cleaning process involves using suitable dust collection and removal equipment, along with appropriate technological processes and proper operating methods, to remove various types of dust mixed into the rice, thereby improving the quality of the finished rice product.
[0003] For example, an existing Chinese patent (publication number: CN215656417U) discloses a rice processing dust removal device. This rice processing dust removal device can efficiently and orderly remove dust from rice, while avoiding damage to the internal air pump and waste of rice caused by the discharge of rice. It is easy to manage, low in cost, and has high dust removal efficiency.
[0004] However, the rice processing dust removal equipment designed above still has some drawbacks in actual use: Although the rice processing dust removal equipment can use an air pump to generate airflow to blow away lighter impurities from the rice and achieve the effect of removing dust from the rice, the effect of blowing out impurities only when the rice falls is poor because the rice falls quickly. It is easy for impurities to be blocked by some rice and thus cannot be blown out.
[0005] To address these issues, we designed a dust collection and removal system for rice processing. Utility Model Content

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a dust collection and removal device for rice processing dust, including a dust collection box 1 with a fan 2 embedded in the top of one side, a feed hopper 3 fixedly inserted into one side of the top of the dust collection box 1, a trapezoidal mesh 4 movably arranged inside the dust collection box 1, a fixing plate 5 fixedly installed on the inner side wall of the dust collection box 1, a turntable 7 rotatably arranged on the front side of the fixing plate 5, a motor 8 arranged on the rear side of the fixing plate 5, the drive shaft of the motor 8 being connected to the turntable 7, a rotating component 9 rotatably arranged between the front side of the turntable 7 and the bottom of the trapezoidal mesh 4, a rotating shaft 6 rotatably arranged on the front side of the fixing plate 5, the turntable 7 being fixedly sleeved on the rotating shaft 6, the drive shaft of the motor 8 rotating through the fixing plate 5 and fixedly connected to the rear end of the rotating shaft 6.
[0026] In practice, rice is fed into the dust collector 1 through the feed hopper 3. At the same time, the fan 2 is turned on, causing the blades on the fan 2 to rotate at high speed to accelerate the airflow and blow out the dust and impurities mixed in with the rice. During this process, the motor 8 is turned on, which causes the drive shaft of the motor 8 to drive the rotating shaft 6 and the turntable 7 to rotate. At the same time, the rotation of the turntable 7 can drive the rotating part 9 to move the trapezoidal mesh 4 up and down, which can make the rice sliding along the trapezoidal mesh 4 bounce up, so that the fan 2 can blow away the dust and impurities mixed in with the rice a second time, thereby improving the dust removal effect.
[0027] See Figure 1-4 A pin 10 is fixedly installed on the front side of the rotating shaft 6. One end of the rotating component 9 is rotatably sleeved on the pin 10. A mounting base 11 is fixedly installed on one side of the bottom of the trapezoidal mesh 4. The other end of the rotating component 9 is rotatably disposed within the mounting base 11. A pin is disposed within the mounting base 11, and the end of the rotating component 9 away from the pin 10 is rotatably sleeved on the pin. This design facilitates the rotation of the rotating component 9 between the front side of the rotating shaft 6 and the bottom of the trapezoidal mesh 4, and also avoids interference issues arising from the movement of the rotating component 9.
[0028] See Figure 1-4 A spring 12 and a telescopic rod 13 are fixedly installed on the top of the trapezoidal mesh 4. The other ends of the spring 12 and the telescopic rod 13 are set on the top wall inside the dust collection box 1. The spring 12 is movably sleeved on the telescopic rod 13.
[0029] In specific implementation, based on the above implementation, the trapezoidal net 4 can be stretched and compressed by the cooperation of spring 12 and telescopic rod 13 during movement, and slide along the direction of the telescopic rod 13 extension end, which can limit the trapezoidal net 4 and avoid the problem of the trapezoidal net 4 moving off course.
[0030] See Figure 1-4 There are four springs 12 and four telescopic rods 13, and the four springs 12 and the four telescopic rods 13 are fixedly installed at the four corners of the top of the trapezoidal net 4. The cooperation of the four springs 12 and the telescopic rods 13 can ensure that the four corners of the top of the trapezoidal net 4 are subjected to balanced forces, thereby avoiding the problem of the trapezoidal net 4 tilting during movement.
[0031] See Figure 1-4 A dust collection box 14 is fixedly installed on one side of the dust collection box 1. The dust collection box 14 and the dust collection box 1 are both provided with a fixing port 15 on the opposite side of the dust collection box 1. The fixing port 15 is connected to the interior of the dust collection box 1.
[0032] In practice, based on the above implementation, after the dust and impurities are blown away from the rice, the impurities and dust can fall into the dust collection box 14 through the fixed port 15, making it convenient to recycle them and avoiding the problem of secondary mixing in the rice.
[0033] See Figure 1-4A trapezoidal component 16 is fixedly installed inside the dust collector 1. The trapezoidal component 16 is located below the trapezoidal mesh 4. A receiving box 17 is provided on the side of the dust collector 1 away from the dust collection box 14. A discharge port 18 is opened on the side of the dust collector 1 away from the fixed port 15. The discharge port 18 is connected to the interior of the dust collector 1, and the receiving box 17 is located diagonally below the discharge port 18.
[0034] In practice, based on the above implementation, the rice after dust removal can fall onto the trapezoidal part 16 along the trapezoidal net 4, and then fall into the receiving box 17 through the discharge port 18 along the trapezoidal part 16, which can be easily collected.
[0035] Before use, all electrical appliances inside and outside the dust collector 1 need to be connected to an external power source, or a battery pack should be installed in an area outside the dust collector 1 that does not obstruct other components. Then, the battery pack and electrical appliances should be connected via wiring. It is also necessary to avoid the wiring from becoming tangled due to the movement of the components. Wiring should be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.
[0036] Working principle: When in use, rice is first injected into the dust collection box 1 through the feed hopper 3. At the same time, the fan 2 needs to be turned on, so that the blades on the fan 2 rotate at high speed to accelerate the airflow and blow out the dust and impurities mixed in the rice. During this process, the motor 8 is turned on, so that the drive shaft of the motor 8 drives the rotating shaft 6 and the turntable 7 to rotate. At the same time, the rotation of the turntable 7 drives the rotating part 9 to move the trapezoidal mesh 4 up and down, which can make the rice sliding along the trapezoidal mesh 4 bounce up, so that the fan 2 can blow away the dust and impurities mixed in the rice a second time, thereby improving the dust removal effect.
[0037] In addition, through the cooperation of spring 12 and telescopic rod 13, the trapezoidal net 4 can stretch and compress spring 12 during movement and slide along the direction of telescopic rod 13, which can limit the trapezoidal net 4 and avoid the problem of the trapezoidal net 4 moving off course.
[0038] After the dust and impurities are blown away from the rice, they can fall into the dust collection box 14 through the fixed port 15 for easy recycling, thus avoiding the problem of secondary mixing with the rice.
[0039] After dust removal, the rice can fall onto the trapezoidal part 16 along the trapezoidal mesh 4, and then fall into the receiving box 17 through the discharge port 18 along the trapezoidal part 16, making it easy to collect.
