Description

Technical Field

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

[0002] Rice processing refers to the process of removing the husk (hull) and bran (chaff) of paddy rice. Paddy rice contains a variety of impurities such as sand, soil, coal dust, iron nails, rice straw, and weed seeds. If these impurities are not completely removed during processing, it will not only affect safe production and reduce the quality of rice, but also be harmful to human health.

[0003] In response, Chinese patent CN215744641U discloses a rice destoner. This destoner can remove stones blocking the filter holes by using a shuffling rod, thereby exposing the holes to allow rice to flow. It can also make the movement of rice in the receiving cavity more abundant, further improving the destoner efficiency of rice. However, the rice after screening is not easy to discharge and requires manual cleaning. Therefore, we propose a rice destoner. Utility Model Content

[0004] The purpose of this invention is to provide a rice destoner that can conveniently remove sand and gravel after screening.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rice destoning machine, comprising a mounting frame, a first filter hole formed on the bottom wall of the mounting frame, a bracket installed at the bottom of the mounting frame, a connecting base plate installed on the bracket, and a discharge assembly communicating with the bottom of the mounting frame. A supporting horizontal plate is installed on the mounting frame, and a transverse scraping assembly is connected to the bottom of the supporting horizontal plate. A rotating assembly is installed on the connecting base plate, one end of which passes through the bottom wall of the mounting frame and is rotatably connected to the bottom of the supporting horizontal plate. The rotating assembly meshes with the transverse scraping assembly. A rotating sleeve is also rotatably connected to the mounting frame, passing through the discharge assembly and sleeved outside the rotating assembly. A scraper is installed outside the rotating sleeve, and a filter plate is rotatably connected to the outside of the rotating sleeve. A second filter hole is formed on the filter plate. A transmission assembly is installed on the supporting horizontal plate, one end of which meshes with the inner side of the rotating sleeve. The transmission assembly meshes with the rotating assembly.

[0006] By adopting the above technical solution, the rice that needs to be destoned is poured into the installation frame, and the filter plate on the rotating sleeve is rotated, causing the first filter hole and the second filter hole to be misaligned. At this time, the rice can be filtered out and discharged from the discharge component. After the rice is filtered out, the filter plate on the rotating sleeve is rotated again, so that the first filter hole and the second filter hole coincide. At this time, the filtered stones can be discharged from the discharge component, which makes it convenient to remove the sand and gravel after screening without the need for manual cleaning.

[0007] By adopting the above technical solution, when screening sand and gravel in rice, the rotating component starts and drives the horizontal scraping component to move back and forth in the horizontal direction. At the same time, the rotating component also drives the rotating sleeve to rotate through the transmission component, so that the scraper outside the rotating sleeve moves in a circle around the rotating sleeve. The movement of the horizontal scraping component and the scraper can disrupt the original path of the rice inside the installation frame. It can also prevent some stones from blocking the filter holes after filtering for a period of time, remove the stones blocking the filter holes, expose the filter holes and allow the rice to flow, and further improve the stone removal efficiency of the rice.

[0008] A further feature of this invention is that the discharge assembly includes a discharge hopper connected to the bottom of the mounting frame and a discharge pipe connected to the bottom of the discharge hopper.

[0009] By adopting the above technical solution, the filtered rice and stones fall into the discharge hopper in sequence and are then discharged through the discharge pipe.

[0010] A further feature of this invention is that the inner bottom wall of the discharge hopper is inclined, and the discharge pipe is connected to the downwardly inclined end of the discharge hopper.

[0011] By adopting the above technical solution, it is convenient to discharge rice and stones that fall into the discharge hopper through the discharge pipe.

[0012] A further feature of this invention is that the filter plate is rotatably connected to the rotating sleeve via a bearing, the filter plate is in contact with the inner bottom wall of the mounting frame, and the scraper is in contact with the surface of the filter plate.

[0013] By adopting the above technical solution, the filter plate will not rotate when the rotating sleeve drives the scraper to rotate, so that the screening aperture will not change easily. The surface of the scraper and the filter plate are in close contact, so that the surface of the filter plate can be scraped when the scraper rotates, avoiding the surface clogging of the filter plate.

[0014] A further feature of this invention is that the transverse scraping assembly includes a connecting side plate installed at the bottom of the supporting horizontal plate, a lead screw rotatably connected to the connecting side plate, a spreading plate threaded to the outside of the lead screw and movably connected to the bottom of the connecting side plate, and a bevel gear installed on the outside of the lead screw.

[0015] A further feature of this invention is that the rotating assembly includes a rotating motor mounted on the connecting base plate, a rotating rod rotatably connected to the supporting horizontal plate and fixedly connected to the output shaft of the rotating motor, and a gear one and a bevel gear two mounted outside the rotating rod.

[0016] A further feature of this invention is that the second bevel gear meshes with the first bevel gear.

[0017] By adopting the above technical solution, the rotating motor starts and drives gear one and bevel gear two on the rotating rod to rotate. When bevel gear two rotates, it drives bevel gear one to rotate. When bevel gear one rotates, it drives the lead screw to rotate. The material spreading plate is threaded to the outside of the lead screw, so that the material spreading plate moves left and right, which disrupts the original route of the rice inside the installation frame and improves the stone removal efficiency of the rice.

[0018] A further feature of this invention is that the rotating rod passes through the rotating sleeve, and the gear is located inside the rotating sleeve.

[0019] By adopting the above technical solution, gear one can mesh with the transmission component to drive the scraper outside the rotating sleeve to rotate.

[0020] A further feature of this invention is that the transmission assembly includes a connecting rod mounted on the support plate and extending into the interior of the rotating sleeve, and a second gear mounted on the outside of the connecting rod, the second gear meshing with the first gear.

[0021] A further feature of this invention is that the transmission assembly further includes a gear ring installed inside the rotating sleeve, and the second gear meshes with the gear ring.

[0022] By adopting the above technical solution, when gear one rotates, it drives gear two to rotate outside the connecting rod. When gear two rotates, it drives the gear ring inside the rotating sleeve to rotate, causing the scraper outside the rotating sleeve to rotate. This disrupts the original path of the rice inside the mounting frame and also prevents some stones from blocking the filter holes after filtering for a period of time. The stones blocking the filter holes are removed, thus exposing the filter holes and allowing the rice to flow, further improving the stone removal efficiency of the rice.

[0023] The beneficial effects of this utility model are:

[0024] 1. This rice destoner is made by pouring the rice to be destoned into the installation frame and rotating the filter plate on the rotating sleeve, causing the first and second filter holes to misalign. At this time, the rice can be filtered out and discharged from the discharge component. After the rice is filtered out, the filter plate on the rotating sleeve continues to rotate, causing the first and second filter holes to overlap. At this time, the filtered stones can be discharged from the discharge component, making it convenient to remove the sand and gravel after screening without the need for manual cleaning.

[0025] 2. This rice destoner starts with a rotating motor that drives gear one and bevel gear two on the rotating rod to rotate. When bevel gear two rotates, it drives bevel gear one to rotate. When bevel gear one rotates, it drives the lead screw to rotate. The material spreading plate is threaded to the outside of the lead screw, which causes the material spreading plate to move left and right, disrupting the original path of the rice inside the mounting frame and improving the destonerization efficiency of the rice.

[0026] 3. In this rice destoner, when gear one rotates, it drives gear two to rotate outside the connecting rod. When gear two rotates, it drives the gear ring inside the rotating sleeve to rotate, causing the scraper outside the rotating sleeve to rotate. This disrupts the original path of the rice inside the mounting frame and also prevents some stones from clogging the filter holes after filtering for a period of time. The stones blocking the filter holes are removed, thus exposing the filter holes and allowing the rice to flow, further improving the destone removal efficiency of the rice.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please see Figure 1-2This utility model provides a rice destoning machine, including a mounting frame 1, a first filter hole 2 opened on the inner bottom wall of the mounting frame 1, a bracket 3 installed at the bottom of the mounting frame 1, a connecting base plate 4 installed on the bracket 3, and a discharge component communicating with the bottom of the mounting frame 1. A supporting horizontal plate 7 is installed on the mounting frame 1, and a transverse scraping component is connected to the bottom of the supporting horizontal plate 7. A rotating component is installed on the connecting base plate 4, one end of which passes through the inner bottom wall of the mounting frame 1 and is rotatably connected to the bottom of the supporting horizontal plate 7. The rotating component meshes with the transverse scraping component. A rotating sleeve 8 is also rotatably connected to the mounting frame 1, passing through the discharge component and sleeved outside the rotating component. A scraper 9 is installed outside the rotating sleeve 8. A filter plate 10 is rotatably connected to the outside of the rotating sleeve 8. A second filter hole 11 is opened on the filter plate 10. A transmission component is installed on the supporting horizontal plate 7, one end of which meshes with the inner side of the rotating sleeve 8. The transmission component meshes with the rotating component.

[0033] Pour the rice that needs to be destoned into the installation frame 1, and rotate the filter plate 10 on the rotating sleeve 8 so that the first filter hole 2 and the second filter hole 11 are misaligned. At this time, the rice can be filtered out and discharged from the discharge component. After the rice is filtered out, continue to rotate the filter plate 10 on the rotating sleeve 8 so that the first filter hole 2 and the second filter hole 11 are aligned. At this time, the filtered stones can be discharged from the discharge component, which makes it convenient to remove the sieved sand and gravel without the need for manual cleaning.

[0034] When sieving sand and gravel from rice, the rotating component starts and drives the horizontal scraping component to move back and forth in the horizontal direction. At the same time, the rotating component also drives the rotating sleeve 8 to rotate through the transmission component, so that the scraper 9 outside the rotating sleeve 8 moves in a circle around the rotating sleeve 8. The movement of the horizontal scraping component and the scraper 9 can disrupt the original path of the rice inside the mounting frame 1, and can also prevent some stones from blocking the filter holes after filtering for a period of time. The stones blocking the filter holes can be removed, thereby exposing the filter holes and allowing the rice to flow, further improving the stone removal efficiency of the rice.

[0035] The discharge assembly includes a discharge hopper 5 connected to the bottom of the mounting frame 1 and a discharge pipe 6 connected to the bottom of the discharge hopper 5. The filtered rice and stones fall into the discharge hopper 5 in sequence and are then discharged through the discharge pipe 6.

[0036] The inner bottom wall of the discharge hopper 5 is inclined, and the discharge pipe 6 is connected to the downward inclined end of the discharge hopper 5, so that the rice and stones falling into the discharge hopper 5 can be discharged from the discharge pipe 6.

[0037] The filter plate 10 is rotatably connected to the rotating sleeve 8 via a bearing. The filter plate 10 is in contact with the inner bottom wall of the mounting frame 1, and the scraper 9 is in contact with the surface of the filter plate 10. This ensures that the filter plate 10 will not rotate when the rotating sleeve 8 drives the scraper 9 to rotate, so that the sieve aperture will not easily change. The contact between the scraper 9 and the surface of the filter plate 10 allows the scraper 9 to scrape the surface of the filter plate 10 when it rotates, thus preventing the surface of the filter plate 10 from becoming clogged.

[0038] The transverse scraping assembly includes a connecting side plate 12 installed at the bottom of the supporting horizontal plate 7, a lead screw 13 rotatably connected to the connecting side plate 12, a spreading plate 14 threaded to the outside of the lead screw 13 and movably connected to the bottom of the connecting side plate 12, and a bevel gear 15 installed on the outside of the lead screw 13. The rotating assembly includes a rotating motor 16 installed on the connecting base plate 4, a rotating rod 17 rotatably connected to the supporting horizontal plate 7 and fixedly connected to the output shaft of the rotating motor 16, and a gear 18 and a bevel gear 19 installed on the outside of the rotating rod 17, with the bevel gear 19 meshing with the bevel gear 15.

[0039] The rotating motor 16 starts and drives the gear 18 and bevel gear 19 on the rotating rod 17 to rotate. When bevel gear 19 rotates, it drives bevel gear 15 to rotate. When bevel gear 15 rotates, it drives the lead screw 13 to rotate. The spreading plate 14 is threaded to the outside of the lead screw 13, so that the spreading plate 14 moves left and right, which disrupts the original path of the rice inside the mounting frame 1 and improves the stone removal efficiency of the rice. The bottom of the spreading plate 14 is equipped with bristles, so that when the spreading plate 14 moves back and forth to disrupt the original path of the rice inside the mounting frame, it will not affect the rotation of the scraper 9.

[0040] The rotating rod 17 passes through the rotating sleeve 8, and the gear 18 is located inside the rotating sleeve 8, so that the gear 18 can mesh with the transmission component to drive the scraper 9 outside the rotating sleeve 8 to rotate.

[0041] The transmission assembly includes a connecting rod 20 mounted on the supporting cross plate 7 and extending into the interior of the rotating sleeve 8, and a second gear 22 mounted on the outside of the connecting rod 20. The second gear 22 meshes with the first gear 18. The transmission assembly also includes a gear ring 21 mounted on the inside of the rotating sleeve 8, and the second gear 22 meshes with the gear ring 21.

[0042] When gear 18 rotates, it drives gear 22 to rotate outside the connecting rod 20. When gear 22 rotates, it drives the gear ring 21 inside the rotating sleeve 8 to rotate, causing the scraper 9 outside the rotating sleeve 8 to rotate. This disrupts the original path of the rice inside the mounting frame 1 and also prevents some stones from blocking the filter holes after filtering for a period of time. The stones blocking the filter holes are removed, thus exposing the filter holes and allowing the rice to flow, further improving the stone removal efficiency of the rice.
