Description

Technical Field

[0001] The utility model relates to the technical field of rice cake production, and specifically relates to a rice efficient and uniform grinding device. Background Art

[0002] Rice cake is a traditional food and one of the indispensable delicacies on New Year's Day in some areas. Rice cake is usually made by steaming sticky rice or glutinous rice, beating or grinding it into powder, and then pressing it. Another way is to dry the washed rice first, then grind it into powder, and then add liquid to make rice cake.

[0003] After searching, a rice milling device disclosed in the publication number CN217120406U is roughly described as comprising a shell, a discharge base is fixedly installed on the bottom inner wall of the shell, a support leg is fixedly installed on the bottom of the discharge base, and a discharge pipe is fixedly installed at the bottom and in the middle of the discharge base. The rice milling device for rice processing squeezes and crushes the rice through a crushing roller, so that the rice particles become smaller, and then grinds the rice into powder through a grinding bottom plate and an upper grinding plate. The efficiency of grinding is improved by pre-crushing, thereby improving the processing efficiency. The power motor drives the current limiting roller to rotate, and the current limiting roller rotates through a quantitative feeding trough provided on the outer wall to convey the rice in the hopper downward. The amount of rice conveyed each time is fixed, thereby preventing the problem of blockage caused by too fast feeding speed or too slow feeding affecting the processing efficiency.

[0004] The above technical solution uses a rotating flow-limiting roller to convey the material downward, so that the amount of material is fixed during each conveying process. Although this method can effectively fix the material conveying amount, during use, since the size of the groove on the flow-limiting roller is fixed, when it rotates, the material can only be conveyed after the groove is aligned with the feeding hopper, and the material cannot be conveyed continuously. As a result, the crushing and crushing roller cannot convey the material in time after crushing the material, causing the crushing and crushing roller to idle, resulting in waste. Utility Model Content

[0005] The utility model aims to provide a rice efficient and uniform grinding device, which solves the problem that the size of the groove on the flow-limiting roller is fixed, and when the groove is rotated, the material can be transported only after it is aligned with the feeding hopper, and the material cannot be transported all the way, which will cause the crushing and rolling roller to be unable to transport the material in time after rolling the material, causing the crushing and rolling roller to run idle and causing waste.

[0006] The utility model provides the following technical solution: a rice efficient and uniform grinding device, comprising a grinder body, the upper top of the grinder body is fixedly connected with a lower hopper, the outer side wall of the grinder body is fixedly connected with an L-shaped bracket, the inside of the grinder body is symmetrically rotatably connected with a grinding roller for rolling and grinding materials, the upper top of the L-shaped bracket is provided with a power structure for driving the grinding roller to work, and the inside of the grinder body is provided with a guide component for controlling the falling of materials above the grinding roller.

[0007] With the above scheme, the material enters the interior of the grinder body through the lower hopper and is regularized by the guide assembly. Then the material falls into the gap between the two grinding rollers through the guidance of the guide structure. When the power structure drives the grinding rollers to rotate, the material in the gap can be ground by extrusion to form the corresponding powder.

[0008] As a preferred embodiment of the above technical solution, the power structure includes a servo motor fixedly connected to the top of the L-shaped bracket, the output end of the servo motor is fixedly connected to a driving rod, the ends of the two grinding rollers are fixedly connected to extension rods, and the extension rods extend to the outer side wall of the grinder body, one of the extension rods is fixedly connected to the end of the driving rod, the outer wall of the extension rod is fixedly sleeved with a transmission gear, and the two transmission gears are meshed with each other.

[0009] With the above scheme, the servo motor drives the driving rod and the extension rod of the grinding roller to rotate, and the rotation of the extension rod drives the two meshing gears to rotate. At this time, the rotation directions of the two grinding rollers are opposite, and when the material falls into the gap between the two grinding rollers, the grinding rollers and the material are squeezed against each other, thereby achieving a grinding effect.

[0010] As a preferred embodiment of the above technical solution, the guide assembly includes a driving structure and a guiding structure, the driving structure includes two unloading plates rotatably connected to the inner wall of the grinder body and located above the grinding roller, the inner wall of the grinder body is located below the unloading plate and the lower bottom end of the unloading plate are fixedly connected with a plurality of first fixed brackets, and an auxiliary telescopic bracket and an electric push rod are arranged at the interval between the two first fixed brackets.

[0011] By adopting the above scheme, when the telescopic end of the electric push rod is working, it can drive the unloading plate to flip, and the auxiliary telescopic frame can stabilize the unloading plate, and the auxiliary telescopic frame can also cooperate with the telescopic end of the electric push rod to extend and retract, so as to avoid the telescopic end of the electric push rod being subjected to greater pressure due to excessive material.

[0012] As a preferred embodiment of the above technical solution, the driving structure also includes a second fixed bracket fixedly connected to the auxiliary telescopic frame and the telescopic end of the electric push rod, the auxiliary telescopic frame and the electric push rod are rotatably connected with the first fixed bracket through the second fixed bracket, and the electric push rod is located in the middle of the interval between the two auxiliary telescopic frames.

[0013] By adopting the above scheme, when the electric push rod drives the blanking plate to flip, the second fixed bracket and the first fixed bracket will cooperate with each other, thereby achieving the purpose of stability.

[0014] As a preferred embodiment of the above technical solution, the guiding structure includes a guide rod fixedly connected to the end of the blanking plate, the inner side wall of the grinding machine body is symmetrically fixedly connected with a fixing plate, the outer side wall of the fixing plate is symmetrically provided with a guide groove for limiting the rotation angle of the blanking plate, and the end of the guide rod is located inside the guide groove.

[0015] By adopting the above scheme, the blanking plate will flip over under the drive of the telescopic end of the electric push rod. In order to make the blanking plate flip more stably, the guide groove and the guide rod cooperate with each other to make it rotate along the inside of the guide groove to achieve stability.

[0016] As a preferred embodiment of the above technical solution, after the two unloading plates are flipped open, an opening is formed for materials to pass through, and the size of the opening is determined according to the position of the guide rod inside the guide groove.

[0017] By adopting the above scheme, the opening setting can allow the material to pass through stably, and the closer the guide rod is to the inner bottom end of the guide groove, the larger the angle of the opening. In this way, the blanking plate can be stabilized, and after the blanking plate is reset, the guide groove can prevent the blanking plate from flipping too much, resulting in not being on the same plane when reset.

[0018] As a preferred embodiment of the above technical solution, a material discharge frame for discharging the material is fixedly connected to the inner side wall of the grinder body below the grinding roller, and the material discharge frame extends to the outer side wall of the grinder body.

[0019] By adopting the above solution, the ground materials can be moved out of the interior of the grinder body through the unloading frame, so that they can be collected more conveniently.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the utility model, a guide assembly is provided, and when in use, the end of the electric push rod is used to drive the blanking plate to flip. During the flipping process, the end of the blanking plate will move inside the guide groove and flip according to the shape of the guide groove. As the two blanking plates are flipped open, the material will flow through the gap formed between the two blanking plates and fall on the interval between the two grinding rollers, and the material will be crushed by the grinding rollers. In this way, it is ensured that the material can be crushed smoothly, and the idling of the grinding roller is avoided. The interval between the two blanking plates can be adjusted to control the amount and speed of the falling material. BRIEF DESCRIPTION OF THE DRAWINGS
