Description

Technical Field

[0001] The present invention relates to the technical field of rice processing, and particularly to a leveling device for rice processing. Background Technique

[0002] Rice processing is the process of converting paddy into edible rice, mainly including cleaning, hulling, milling, polishing, grading and other links. The whole process needs to control temperature, humidity and pressure to retain the nutritional components of rice and improve the taste. At the same time, the rice husks and rice bran produced can be reused as feed or industrial raw materials.

[0003] A Chinese patent with the publication number CN118637391A discloses a rice leveling device for rice production, including a first feeding frame and a hopper. The bottom end of the first feeding frame is fixedly connected with four groups of first springs. The bottom ends of the first springs are fixedly connected to the top end of the fixed frame. The first springs are located at the four corners of the first feeding frame. The bottom end of the fixed frame is fixedly connected with support columns. The hopper is located directly below the fixed frame. A leveling mechanism is arranged on the first feeding frame, and the leveling mechanism is used to level the rice in the first feeding frame. A first shaking mechanism is arranged at the bottom end of the first feeding frame, and the first shaking mechanism is used to shake the rice in the first feeding frame. A second shaking mechanism is arranged on the fixed frame; through the structural design of the leveling mechanism, the rice poured onto the first feeding frame is leveled, avoiding the appearance of too high rice piles locally.

[0004] The existing related technologies often have the following defects: However, in the actual use process of the existing flattening structure, when using the above structure to flatten rice, it is difficult to efficiently complete the rapid flattening operation of rice, and it cannot meet the working requirements of the rice flattening work.

[0005] Therefore, we propose a leveling device for rice processing. Summary of the Invention

[0006] The purpose of the present invention is to provide a leveling device for rice processing to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A leveling device for rice processing, including a blanking frame, and a filter screen is fixedly installed inside the blanking frame. It also includes: a flattening structure arranged above the blanking frame for flattening the rice during the blanking process above the filter screen of the blanking frame; a impurity removing structure arranged above the blanking frame for blowing away the rice husk impurities contained in the rice during the flattening process; a collecting structure arranged on the side wall of the blanking frame for collecting the blown rice husk impurities.

[0008] The effects achieved by the above components are as follows: By setting the flattening structure, it facilitates the flattening work of the rice during the feeding process using the flattening frame. And while the flattening frame is moving for feeding, the structure on the lower end side can further flatten the rice, improving the flattening efficiency of the rice and meeting the requirements of the rice flattening work. By setting the impurity removal structure, it uses air flow to blow away the rice husks contained inside the rice during the flattening process, further improving the processing efficiency of the rice. By setting the collection structure, it facilitates the collection of the rice husks blown to one side position of the rice, facilitating the centralized treatment of the rice husks after impurity removal, and further improving the service performance of the flattening structure.

[0009] Preferably, the flattening structure includes a guide rail fixedly connected to the side wall of the feeding frame. A driving frame is slidably installed on the side wall of the guide rail. A flattening frame is slidably connected to the inside of the driving frame. The upper side of the flattening frame is a hopper structure, and the lower side of the flattening frame is a square tube structure. A plurality of reserved slots are opened on the lower end side of the flattening frame.

[0010] The effects achieved by the above components are as follows: The hopper structure on the upper side of the flattening frame guides the rice to be evenly fed. The reserved slots on the lower end side cut the rice pile during the movement, eliminating the height difference.

[0011] Preferably, an installation frame is fixedly connected to the side wall of the feeding frame. The installation frame is spliced by rods and rings. A servo motor is fixedly installed inside the installation frame. A lead screw is rotatably installed inside the feeding frame. The lead screw is threadedly connected to the inside of the driving frame. The output end of the servo motor is fixedly connected to the end side of the lead screw.

[0012] The effects achieved by the above components are as follows: The servo motor drives the lead screw to rotate, driving the driving frame to perform a reciprocating linear motion along the guide rail, and then pushing the flattening frame to move horizontally.

[0013] Preferably, a first positioning block and a second positioning block are respectively fixedly installed on both sides of the flattening frame. A limit pin is slidably connected to the inside of the first positioning block. The lower end of the limit pin is fixedly connected to the driving frame. A driving rod is threadedly connected to the inside of the second positioning block. The driving rod is rotatably connected to the inside of the driving frame.

[0014] The effects achieved by the above components are as follows: Rotating the driving rod, adjusting the vertical distance between the flattening frame and the filter screen through screw drive to adapt to the flattening requirements of rice layers with different thicknesses. The sliding fit between the limit pin and the first positioning block ensures that the flattening frame remains horizontal during movement, avoiding uneven flattening caused by tilting.

[0015] Preferably, a impurity removing structure is provided on the surface of the flattening frame. The impurity removing structure includes an air pump fixedly connected to the surface of the flattening frame. An air suction pipe and an air outlet pipe are fixedly installed on the surface of the air pump. An installation pipe is fixedly communicated with the surface of the air outlet pipe. A wind pipe is fixedly connected to the lower side of the flattening frame. An installation pipe is communicated between the wind pipe and the air outlet pipe. A plurality of air blowing holes are formed at the inclined surface position of the lower side of the wind pipe.

[0016] The effects achieved by the above components are as follows: During the process of moving the flattening frame, the air pump is started. The air pump inhales air through the air suction pipe, transports it through the air outlet pipe and the installation pipe to the wind pipe, and sprays the air flow obliquely downward from the air blowing holes. The air flow acts on the surface of the flattened rice, and uses the density difference between the rice husks and the rice to blow the lightweight rice husks upward.

[0017] Preferably, a first screen is fixedly connected to the end side of the air suction pipe.

[0018] The effects achieved by the above components are as follows: The first screen filters the dust in the inhaled air.

[0019] Preferably, a second screen is fixedly connected to the inner side of the air blowing hole.

[0020] The effects achieved by the above components are as follows: The second screen prevents rice grains from entering the wind pipe, ensuring that the air flow is pure and does not block the pipeline.

[0021] Preferably, the collection structure includes a impurity collection port formed on the side wall of the blanking frame, and a baffle is fixedly connected to the upper side of the blanking frame.

[0022] The effects achieved by the above components are as follows: By setting the baffle, the collection efficiency of the rice husk impurities is further improved.

[0023] Preferably, two L-shaped support blocks are fixedly connected to the surface of the blanking frame. Two limit blocks are fixedly connected to the surface of the blanking frame. A rectangular ring is slidably installed between the two limit blocks and the support blocks. A collection bag is fixedly connected to the end side of the rectangular ring. The collection bag is a soft mesh structure.

[0024] The effects achieved by the above components are as follows: The rice husks will eventually fall into the collection bag. The rectangular ring is slidably installed through the limit blocks and the support blocks, and the collection bag can be quickly disassembled for dumping.

[0025] Preferably, an elastic pad is adhesively bonded to the surface of the rectangular ring.

[0026] The effects achieved by the above components are as follows: The elastic pad ensures the sealing at the interface and avoids the leakage of impurities.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. The present invention facilitates the leveling work during the feeding process of rice by using a leveling frame through the provision of a leveling structure. Moreover, while the leveling frame is moving for feeding, the structure on the lower end side can be used to further level the rice, improving the leveling efficiency of the rice and meeting the requirements of the rice leveling work.

[0029] 2. The present invention realizes the treatment of rice containing rice husks during the leveling process by setting up a impurity removal structure. During the process of moving the leveling frame, the air pump is started. The air pump inhales air through the suction pipe, and conveys it to the air duct through the air outlet pipe and the installation pipe, and the air flows out obliquely downward from the air blowing holes. Acting on the surface of the leveled rice, using the density difference between the rice husks and the rice, the lightweight rice husks are blown up, thus realizing the treatment of the rice husks contained in the rice during the leveling process. By setting up the impurity removal structure, the work of blowing away the rice husks contained inside the rice during the leveling process by using air flow further improves the processing efficiency of the rice.

[0030] 3. The present invention facilitates the collection work of the rice husks blown to one side of the rice by setting up a collection structure. The blown-up rice husks fall into the inner side of the collection bag along the impurity collection port. By setting up the baffle, the collection efficiency of the rice husk impurities is further improved. The rice husks will eventually fall into the collection bag. The rectangular ring is slidably installed on the support block through the limit block, and the collection bag can be quickly disassembled for dumping. By setting up the collection structure, it is convenient for the collection work of the rice husks of the rice blown to one side position, and convenient for the centralized treatment work of the rice husks after impurity removal, further improving the service performance of the leveling structure.

Detailed implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-8 , the present invention provides a technical solution: a flattening device for rice processing, including a blanking frame 1, and a filter screen 2 is fixedly installed inside the blanking frame 1. It further includes: a flattening structure 3 arranged on the upper side of the blanking frame 1 for flattening the rice above the filter screen 2 of the blanking frame 1 during the blanking process; an impurity removing structure 4 arranged above the blanking frame 1 for blowing away the rice husk impurities contained in the rice during the flattening process; a collection structure 5 arranged on the side wall of the blanking frame 1 for collecting the blown rice husk impurities. By setting the flattening structure 3, it is convenient to use the flattening frame 301 to flatten the rice during the blanking process, and while the flattening frame 301 is moving for blanking, the structure on the lower end side can be used to further flatten the rice, improving the flattening efficiency of the rice and meeting the requirements of the rice flattening work. By setting the impurity removing structure 4, the air flow is used to blow away the rice husk contained in the rice during the flattening process, further improving the processing efficiency of the rice. By setting the collection structure 5, it is convenient to collect the rice husk blown to one side position of the rice, facilitating the centralized treatment of the rice husk after impurity removal, and further improving the service performance of the flattening structure 3.

[0042] Next, the specific settings and functions of its flattening structure 3, impurity removing structure 4 and collection structure 5 will be specifically described.

[0043] As Figures 1-3As shown in the figure, the flattening structure 3 includes a guide rail 305 fixedly connected to the side wall of the blanking frame 1. A driving frame 306 is slidably installed on the side wall of the guide rail 305. A flattening frame 301 is slidably connected to the inner side of the driving frame 306. The upper side of the flattening frame 301 is a hopper structure, and the lower side of the flattening frame 301 is a square tube structure. A plurality of reserved slots 307 are opened on the lower end side of the flattening frame 301. The hopper structure on the upper side of the flattening frame 301 guides the rice to be evenly discharged. The reserved slots 307 on the lower end side cut the rice pile during the movement to eliminate the height difference. An installation frame 302 is fixedly connected to the side wall of the blanking frame 1. The installation frame 302 is spliced by a rod and a ring. A servo motor 303 is fixedly installed inside the installation frame 302. A lead screw 304 is rotatably installed inside the blanking frame 1. The lead screw 304 is threadedly connected to the inside of the driving frame 306. The output end of the servo motor 303 is fixedly connected to the end side of the lead screw 304. The servo motor 303 drives the lead screw 304 to rotate, driving the driving frame 306 to perform a reciprocating linear motion along the guide rail 305, and then pushing the flattening frame 301 to move horizontally. First positioning blocks 308 and second positioning blocks 310 are respectively fixedly installed on both sides of the flattening frame 301. A limit pin 309 is slidably connected to the inside of the first positioning block 308. The lower end of the limit pin 309 is fixedly connected to the driving frame 306. A driving rod 311 is threadedly connected to the inside of the second positioning block 310. The driving rod 311 is rotatably connected to the inside of the driving frame 306. By rotating the driving rod 311, the vertical distance between the flattening frame 301 and the filter screen 2 is adjusted through threaded transmission to meet the flattening requirements of rice layers with different thicknesses. The sliding fit between the limit pin 309 and the first positioning block 308 ensures that the flattening frame 301 remains horizontal during movement, avoiding uneven flattening caused by tilting.

[0044] As Figures 1-6 shown, a impurity removal structure 4 is provided on the surface of the flattening frame 301. The impurity removal structure 4 includes an air pump 41 fixedly connected to the surface of the flattening frame 301. An air suction pipe 44 and an air outlet pipe 45 are fixedly installed on the surface of the air pump 41. An installation pipe 42 is fixedly communicated with the surface of the air outlet pipe 45. An air duct 43 is fixedly connected to the lower side of the flattening frame 301. The installation pipe 42 communicates between the air duct 43 and the air outlet pipe 45. A plurality of air blowing holes 47 are opened at the lower inclined surface position of the air duct 43. During the movement of the flattening frame 301, the air pump 41 is started. The air pump 41 sucks air through the air suction pipe 44, and transports it to the air duct 43 through the air outlet pipe 45 and the installation pipe 42, and the air flow is sprayed obliquely downward from the air blowing holes 47. The air flow acts on the surface of the flattened rice, and uses the density difference between the rice husk and the rice to blow the lightweight rice husks up. A first screen 46 is fixedly connected to the end side of the air suction pipe 44. The first screen 46 filters the dust in the inhaled air. A second screen 48 is fixedly connected to the inner side of the air blowing holes 47. The second screen 48 prevents rice grains from entering the air duct 43, ensuring that the air flow is pure and does not block the pipeline.

[0045] As Figures 1-2 andFigure 7 and Figure 8 As shown, the collection structure 5 includes a miscellaneous collection port 52 opened on the side wall of the blanking frame 1, and a baffle 53 is fixedly connected to the upper side of the blanking frame 1. By setting the baffle 53, the collection efficiency of rice husk impurities is further improved. Two L-shaped support blocks 55 are fixedly connected to the surface of the blanking frame 1, and two limit blocks 54 are fixedly connected to the surface of the blanking frame 1. A rectangular ring 56 is slidably installed between the two limit blocks 54 and the support blocks 55. A collection bag 51 is fixedly connected to the end side of the rectangular ring 56. The collection bag 51 is a soft mesh structure. The rice husks will finally fall into the collection bag 51. The rectangular ring 56 is slidably installed through the limit blocks 54 and the support blocks 55, and the collection bag 51 can be quickly disassembled for dumping. An elastic pad 57 is adhesively bonded to the surface of the rectangular ring 56. The elastic pad 57 ensures the seal at the interface and avoids the leakage of impurities.

[0046] Working principle: When blanking work needs to be carried out, the rice material can be directly put into the inner side of the flattening frame 301. The square tube structure on the lower side of the flattening frame 301 can reduce the phenomenon of rice piles. The servo motor 303 drives the lead screw 304 to rotate, driving the drive frame 306 to make a reciprocating linear motion along the guide rail 305, and then pushing the flattening frame 301 to move horizontally. The hopper structure on the upper side of the flattening frame 301 guides the rice to be evenly blanked. The reserved groove 307 at the lower end side cuts the rice pile during the movement to eliminate the height difference. When the flattening force needs to be adjusted, the drive rod 311 is rotated, and the vertical distance between the flattening frame 301 and the filter screen 2 is adjusted through screw transmission to adapt to the flattening requirements of rice layers with different thicknesses. The sliding fit between the limit pin 309 and the first positioning block 308 ensures that the flattening frame 301 remains horizontal during movement, avoiding uneven flattening caused by tilting. By setting the flattening structure 3, it is convenient to use the flattening frame 301 to carry out the flattening work during the blanking process of rice, and the structure on the lower end side of the flattening frame 301 can further flatten the rice while moving and blanking, improving the flattening efficiency of rice and meeting the requirements of the rice flattening work.

[0047] During the process of moving the flattening frame 301, the air pump 41 is started. The air pump 41 sucks in air through the suction pipe 44, transports it through the air outlet pipe 45 and the installation pipe 42 to the air duct 43, and sprays out the air flow obliquely downward from the air blowing holes 47. The air flow acts on the surface of the flattened rice. Utilizing the density difference between the rice husks and the rice, the lightweight rice husks are blown up, thus realizing the treatment of the rice containing rice husks during the flattening process. By setting the reserved groove 307 on the lower side of the flattening frame 301, the rice pile can be cut during the movement, and the rice husks pressed at the bottom side can be turned out, further improving the impurity removal effect of the rice containing rice husks. The first screen 46 filters the dust in the inhaled air, and the second screen 48 prevents rice grains from entering the air duct 43, ensuring that the air flow is pure and the pipeline is not blocked. By setting the impurity removal structure 4, the blowing away of the rice husks contained inside the rice during the flattening process by the air flow further improves the processing efficiency of the rice.

[0048] The blown-up rice husks fall into the inner side of the collection bag 51 along the impurity collection port 52. By setting the baffle 53, the collection efficiency of the rice husk impurities is further improved. The rice husks will eventually fall into the collection bag 51. The rectangular ring 56 is slidably installed with the support block 55 through the limit block 54, and the collection bag 51 can be quickly disassembled for dumping. The elastic pad 57 ensures the sealing of the interface and avoids the leakage of impurities. The mesh size of the collection bag 51 can intercept the rice husks and allow fine dust to pass through, facilitating subsequent centralized treatment. By setting the collection structure 5, it is convenient for the collection of the rice husks blown to one side of the rice, and it is convenient for the centralized treatment of the rice husks after impurity removal, further improving the service performance of the flattening structure 3.
