Description

Technical Field

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

[0002] As people's living standards continue to improve, the demand for clean rice is constantly increasing. This requires polishing the rice during the processing of rice before further processing steps, and finally packaging and shipping the rice.

[0003] In existing technologies, such as the rice polishing machine disclosed in Chinese Patent Publication No. CN208356860U, a first polishing chamber and a second polishing chamber are set inside the main body of the rice polishing machine. The first polishing chamber and the second polishing chamber are respectively equipped with a first polishing roller and a second polishing roller. Rice is pushed into the first polishing chamber by a pusher set on the polishing roller. The first polishing roller polishes the rice. After the first polishing is completed, a pusher set on the other side pushes the rice into a guide pipe. The rice in the backflow pipe enters the second polishing chamber for a second polishing. The second polishing can make the rice polished more thoroughly. A dust collection box is set below the discharge hopper. When the rice falls onto the dust and rice surface filter plate, the dust and rice powder generated during polishing are filtered out by the filter screen, resulting in higher quality rice output and saving the second screening of rice, thus saving steps in rice production.

[0004] However, existing rice polishing machines require rice to be fed into the machine through a feeding device during polishing operations. Since rice is granular, it is easy for rice to overflow during the feeding process, resulting in the rice not being able to fully enter the polishing machine. Furthermore, the existing feeding device is bulky and cannot be moved, requiring the polishing machine to be moved below the feeding device for feeding, which is quite troublesome. Therefore, the above problems need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a rice polishing machine, which has the advantages of good feeding effect and convenient feeding.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a rice polishing machine, including a walking mechanism, a rice bin is provided on the outer side of the walking mechanism, a discharge pipe is fixedly connected to the bottom of the rice bin, slide rails are provided on both sides of the inner wall of the discharge pipe, an extension pipe is slidably connected inside the slide rails, an electric gate is provided inside the extension pipe, mounting blocks are fixedly connected to both sides of the extension pipe, electric push rods are fixedly connected to both sides of the bottom of the rice bin, the electric push rods are fixed inside the mounting blocks, a support column is fixedly connected to the outside of the rice bin, a pulley frame is fixedly connected to the bottom of the support column, a pulley is rotatably connected inside the pulley frame, a positioning block is fixedly connected to the outer side of the walking mechanism, and a bolt is threadedly connected inside the positioning block.

[0007] By adopting the above technical solution, the walking mechanism is fixed to the base surface of the workshop by positioning blocks and bolts. The support columns support both sides of the rice bin. The walking mechanism drives the rice bin to move. During the movement, the pulleys will contact the ground and rotate inside the pulley frame, thus driving one side of the rice bin through the walking mechanism to achieve the purpose of movement. The support columns, pulley frame, and pulleys support the other side of the rice bin, improving the stability of movement. Multiple polishing machines are set below the rice bin. Through the movement of the rice bin, one rice bin can feed multiple polishing machines at the same time, improving the feeding efficiency of rice. When rice is put into the polishing machine, the electric push rod is activated, which drives the extension tube to extend and retract through the mounting block. The extension tube extends and retracts inside the discharge pipe through the slide, extending the extension tube to the feed port of the polishing machine. Then the electric gate is opened, allowing the rice to be injected into the feed port of the polishing machine through the extension tube. During this process, it can prevent rice from overflowing and prevent small amounts of rice from failing to enter the polishing machine.

[0011] By adopting the above technical solution, the motor is started, which drives the threaded shaft to rotate. The sleeve is threadedly connected to the threaded shaft, and the rice bin is fixed outside the sleeve, thereby enabling the rice bin to move.

[0012] A further feature of this invention is that a motor housing is fixedly connected to the outside of the track, and the motor is located inside the motor housing.

[0013] By adopting the above technical solution, the motor housing covers the motor to prevent it from being impacted.

[0014] A further feature of this invention is that the motor housing has heat dissipation holes inside, and a filter screen is fixedly connected inside the heat dissipation holes.

[0015] By adopting the above technical solution, the heat generated by the motor is discharged through the heat dissipation holes, which cover the filter screen to prevent dust from entering the motor box.

[0016] A further feature of this invention is that the top of the rice bin has a feed inlet.

[0017] By adopting the above technical solution, rice enters the rice silo through the feed inlet and is stored in the rice silo.

[0018] A further feature of this invention is that: both sides of the inner wall of the rice bin are provided with sliding grooves, and a foldable plastic plate is slidably connected inside the sliding grooves.

[0019] By adopting the above technical solution, the foldable plastic sheet is slidably connected to the inside of the rice bin via a slide groove. One end of the foldable plastic sheet is fixed inside the slide groove, while the other end of the foldable plastic sheet can slide inside the slide groove and can be displaced inside the rice bin.

[0020] A further feature of this invention is that a cylinder is fixedly installed on the inner wall of the rice bin, a push rod is provided at the output end of the cylinder, a push block is fixedly connected to one side of the foldable plastic plate, and the push rod is fixed to the outside of the push block.

[0021] By adopting the above technical solution, the cylinder is activated, which drives the push rod to extend and retract.

When the push rod is retracted, the foldable plastic plate will be folded, the feed inlet will be opened, and the rice can enter the rice bin through the discharge port.

[0022] A further feature of this invention is that a cylinder bracket is fixedly installed on the inner wall of the rice bin, and the cylinder is fixed inside the cylinder bracket.

[0023] By adopting the above technical solution, the cylinder is fixed inside the rice bin by a cylinder bracket, which improves the stability of the cylinder during operation.

[0024] A further feature of this invention is that a glass layer is fixedly connected to the outside of the rice bin, and the glass layer is transparent.

[0025] By adopting the above technical solution, staff can understand the amount of rice stored inside the rice warehouse by observing the transparent glass layer.

This utility model, through the arrangement of a walking mechanism, rice bin, discharge pipe, slide rail, extension pipe, electric gate, mounting block, electric push rod, support column, pulley frame, pulley, positioning block, and bolts, fixes the walking mechanism to the base surface of the workshop via positioning blocks and bolts. The support column supports both sides of the rice bin. The walking mechanism drives the rice bin to move. During movement, the pulley will contact the ground and rotate inside the pulley frame, thus driving one side of the rice bin through the walking mechanism to achieve the purpose of movement. The support column, pulley frame, and pulley support the other side of the rice bin, lifting it. For stability, multiple polishing machines are positioned below the rice silo. The movement of the rice silo allows one silo to simultaneously feed multiple polishing machines, improving rice feeding efficiency. When rice is being fed into the polishing machine, an electric push rod is activated, causing the extension tube to extend and retract via a mounting block. The extension tube extends and retracts inside the discharge pipe via a slide rail, reaching the polishing machine's feed inlet. Then, an electric gate is opened, allowing rice to flow into the polishing machine's feed inlet through the extension tube. This process prevents rice from overflowing and ensures that small amounts of rice do not fail to enter the polishing machine.

[0028] 2. This utility model, through the arrangement of the feed inlet, chute, foldable plastic plate, cylinder, push rod, push block, cylinder bracket, and glass layer, allows the foldable plastic plate to slide inside the rice bin via the chute. One end of the foldable plastic plate is fixed inside the chute, while the other end can slide inside the chute and move within the rice bin. Activating the cylinder drives the push rod to extend and retract, which in turn causes the push block and foldable plastic plate to extend and retract. When the push rod is pushed forward, the foldable plastic plate will be laid flat inside the feed inlet, effectively blocking dust from entering the rice bin. When the push rod is retracted, the foldable plastic plate will fold, opening the feed inlet and allowing rice to enter the rice bin through the discharge port. Attached Figure Description
