Description

Technical Field

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

[0002] Rice is a finished product made from paddy through processes such as hulling, milling, and finishing. However, rice may contain some impurities during the acquisition process, so these impurities need to be removed before the rice is fed into the processing plant.

[0003] A search revealed a rice processing feed filtration device (authorization announcement number CN216225400U). Addressing the low filtration efficiency of existing technologies that rely solely on statically placed screens, the device proposes the following solution: It includes a sleeve containing a fixed cylinder. A sliding cylinder is slidably disposed within the cylinder. Limit grooves are formed on both inner walls of the cylinder. Limit blocks are fixedly disposed on both sides of the sliding cylinder, with the two limit blocks slidably disposed within corresponding limit grooves. A screen plate with screen holes is fixedly disposed within the sliding cylinder. A first spring is fixedly disposed on the top side of each of the two limit blocks.

[0004] However, the above-mentioned rice processing feed filtration device still has shortcomings. The filtration is not thorough enough, and the rice is only screened once, resulting in incomplete screening and filtration. It is also inconvenient to filter out lighter impurities in the rice, which greatly reduces the screening and filtration effect. Therefore, we propose a rice processing feed filtration device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding and filtering device for rice processing, which can filter and screen rice twice, removing both smaller and larger impurities. At the same time, through an air separation mechanism, lighter impurities in the rice can be filtered out, ensuring the cleanliness of the rice and greatly improving the screening and filtering effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding and filtering device for rice processing, comprising a filter box, a conveying cylinder fixedly connected to the top of the filter box, a discharge pipe fixedly connected between the conveying cylinder and the filter box, a conveying and filtering mechanism for conveying rice provided between the filter box and the conveying cylinder, a screen plate movably arranged inside the filter box, a vibrating screen mechanism provided between the screen plate, the filter box and the conveying cylinder, an air separation mechanism provided on the filter box below the screen plate, and a feeding hopper fixedly connected to the top of the conveying cylinder.

[0007] A further feature of this invention is that the conveying and filtering mechanism includes a drive motor fixedly connected to one side of the conveying cylinder, a rotating shaft fixedly connected to the output shaft of the drive motor, an auger fixedly sleeved on the outer side of the rotating shaft, a filter screen fixedly connected to the bottom of the conveying cylinder, and a collection box movably placed on the top of the filter box, with the collection box located directly below the filter screen.

[0008] By adopting the above technical solution, rice is poured into the feed hopper, and the rotating shaft and auger are driven by the drive motor. Under the rotation of the auger, the rice can be conveyed from left to right into the discharge pipe, and then discharged into the filter box for filtration and screening. Because a filter screen is set at the bottom of the conveying cylinder, smaller impurities in the rice can be filtered into the collection box for collection and processing.

[0009] A further feature of this invention is that the top of the filter box is fixedly connected to two support legs, and the conveying cylinder is fixedly connected to the top of the two support legs.

[0010] By adopting the above technical solution, it is beneficial to support and fix the conveyor cylinder.

[0011] The present invention is further configured as follows: the vibrating screen mechanism includes an upper driving pulley fixedly connected to one end of the rotating shaft, a horizontal shaft rotatably connected to one side of the filter box, and four springs fixedly connected to the bottom of the screen plate. An upper driven pulley is fixedly sleeved on the outer side of the horizontal shaft. The upper driving pulley and the upper driven pulley are connected to the same upper belt. An eccentric wheel is fixedly connected to one end of the horizontal shaft. The eccentric wheel movably abuts against the bottom of the screen plate. An upper waste outlet is opened on the other side of the filter box, and the upper waste outlet corresponds to the screen plate.

[0012] By adopting the above technical solution, rice falls onto the screen plate, where larger impurities are filtered out and discharged through the upper impurity outlet. The rice then falls into the filter box below the screen plate. Simultaneously, the rotating shaft drives the upper drive pulley to rotate. Under the transmission of the upper belt, the upper drive pulley drives the upper driven pulley, the horizontal shaft, and the eccentric wheel to rotate. When the eccentric wheel comes into contact with the screen plate, it will cause the screen plate to move upward and stretch the spring. When it is not in contact, the screen plate moves downward and resets under the elastic force of the spring, thereby driving the screen plate to vibrate up and down. This greatly improves the effect and efficiency of rice filtration and screening, while avoiding clogging of the screen plate by larger impurities.

[0013] A further feature of this invention is that four connecting plates are fixedly connected to the inner walls of both sides of the filter box, the bottom ends of four springs are fixedly connected to the top of the corresponding connecting plates, and the connecting plates are fixedly connected to the same telescopic rod, with the four springs respectively sleeved on the outer side of the corresponding telescopic rod.

[0014] By adopting the above technical solution, it is beneficial to support and fix the spring, and at the same time, it is beneficial to guide the screen plate, making its movement more stable and smooth.

[0015] A further feature of this invention is that the air separation mechanism includes a lower driving pulley fixedly sleeved on the outside of the horizontal shaft and a rotating shaft rotatably connected to one side of the filter box. One end of the rotating shaft is fixedly connected to a lower driven pulley, and the lower driving pulley and the lower driven pulley are drivenly connected to the same lower belt. A partition is fixedly connected to the bottom inner wall of the filter box. A fan blade is fixedly connected to the other end of the rotating shaft. A discharge port is fixedly connected to the bottom of one side of the filter box, and a lower impurity outlet is fixedly connected to the other side of the filter box.

[0016] By adopting the above technical solution, the rotation of the horizontal shaft drives the rotation of the lower drive pulley. Under the transmission of the lower belt, the lower drive pulley drives the rotation of the lower driven pulley, the rotating shaft and the fan blade. Under the rotation of the fan blade, smaller impurities in the rice can be blown to the left side of the separator and discharged from the lower impurity outlet, while heavier rice falls to the right side of the separator and is discharged from the discharge outlet.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model uses a drive motor to drive the rotation of the rotating shaft and the auger. Under the rotation of the auger, rice can be conveyed from left to right into the feeding pipe, and then discharged into the filter box for filtration and screening. Because a filter screen is set at the bottom of the conveying cylinder, smaller impurities in the rice can be filtered into the collection box for collection and processing.

[0019] 2. This utility model uses a screen plate to filter out larger impurities in rice, which then fall down the screen plate and are discharged through the upper impurity outlet. The rice falls into the filter box below the screen plate. At the same time, the rotating shaft drives the upper drive pulley to rotate. Under the transmission of the upper belt, the upper drive pulley drives the upper driven pulley, the horizontal shaft, and the eccentric wheel to rotate. When the eccentric wheel comes into contact with the screen plate, it will drive the screen plate to move upward and stretch the spring. When it is not in contact, the screen plate moves downward and resets under the elastic force of the spring, thereby driving the screen plate to vibrate up and down. This greatly improves the effect and efficiency of rice filtration and screening, while avoiding clogging of the screen plate by larger impurities.

[0020] 3. The rotation of the horizontal shaft of this utility model drives the rotation of the lower driving pulley. Under the transmission of the lower belt, the lower driving pulley drives the rotation of the lower driven pulley, the rotating shaft and the fan blade. Under the rotation of the fan blade, smaller impurities in the rice can be blown to the left side of the separating table and discharged from the lower impurity outlet, while heavier rice falls to the right side of the separating table and is discharged from the discharge outlet.
