Technical Field

[0001] The utility model relates to the technical field of grain pretreatment, and specifically relates to a grain pretreatment device for a rice mill. Background Art

[0002] A rice mill uses the mechanical force generated by mechanical equipment to remove the skin of paddy rice and polish it white. It mainly consists of a fixed wrench, a tightening nut wrench, a brush, a feeding hopper, a grinding wheel, a wire brush, etc. However, before milling the grain, it is necessary to pre-treat the grain by drying to prevent the grain from getting damp and moldy, and a pretreatment device for the rice mill is required.

[0003] For example, a grain pretreatment device for a rice mill with the authorization announcement number of "CN220737655U" uses a stirring component to stir the grain in the drying tank in all directions, thereby improving the drying effect, reducing the drying time and drying cost. However, when the grain is exported after drying, due to the rough surface of the grain and low fluidity, and the discharge pipe is relatively narrow, it is easy to cause the discharge pipe to be blocked during discharging, and the staff needs to stop the device and manually dredge it, which slows down the working speed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that due to the rough surface of the grain and low fluidity, and the discharge pipe is relatively narrow, it is easy to cause the discharge pipe to be blocked during discharging, and the staff needs to stop the device and manually dredge it, which slows down the working speed, and a grain pretreatment device for a rice mill is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a grain pretreatment device for a rice mill, including a frame and a third motor. The left end of the outer wall of the frame is fixedly connected to the outer wall of the third motor through a bracket. The output shaft of the third motor is fixedly connected to a rotating shaft. The rotating shaft is rotationally connected to the frame and the tank body through bearings. The rotating shaft of the tank body is rotationally connected to the frame through a bearing. The outer wall of the rotating shaft is fixedly connected to a scraper through multiple struts. A grain pretreatment discharge knocking structure is arranged at the upper end of the outer wall of the tank body. A grain pretreatment discharge structure is arranged at the lower end of the inner wall of the frame.

[0007] Preferably, the grain pre-treatment discharge knocking structure includes a first box body. The upper end of the outer wall of the first box body is fixedly connected with a first motor through a bracket. The output shaft of the first motor is fixedly connected with a drum. The drum is rotationally connected with the first box body through a bearing. The drum is slidably connected with a cylinder protruding from the outer wall of a square block through a chute processed on the outer wall. The square block is slidably connected with the inner wall of the first box body. The left end of the outer wall of the square block is fixedly connected with a vertical plate. The left side of the outer wall of the vertical plate is fixedly connected with a plurality of convex blocks. The outer walls of the plurality of convex blocks are in contact with a cross bar. A spring is sleeved in the middle of the cross bar. The left end of the spring is fixedly connected with the inner wall of the first box body. The right end of the spring is in contact with a protruding part of the outer wall of the cross bar. The cross bar penetrates through the first box body. The outer wall of the cross bar is slidably connected with the first box body. The end of the cross bar is fixedly connected with a rubber block.

[0008] Preferably, the lower end of the outer wall of the first box body is fixedly connected with the upper end of the outer wall of a tank body. The upper end of the outer wall of the tank body is provided with a feed inlet.

[0009] Preferably, a feed box is placed at the lower end of the inner wall of the frame. The four corners of the lower end of the outer wall of the frame extend out with base seats.

[0010] Preferably, the grain pre-treatment discharge structure includes a second motor. The output shaft of the second motor is fixedly connected with a gear. The lower end of the inner wall of the frame is fixedly connected with a straight plate. The rotating shaft of the gear is rotationally connected with the straight plate through a bearing.

[0011] Preferably, the outer wall of the second motor is fixedly connected with the inner wall of the frame through a bracket. A heating plate is fixedly connected to the lower end inside the tank body.

[0012] The beneficial effects of a grain pre-treatment device of a rice mill proposed by the present utility model are as follows: Through the cooperation of the grain pre-treatment discharge structure and the grain pre-treatment discharge knocking structure, when the second motor is started, the gear rotates in the straight plate through a bearing. The rotation of the gear drives the tank body to move towards the feed box through the tooth teeth. When the first motor is started, the drum rotates in the first box body through a bearing. The rotation of the drum drives the square block to reciprocate up and down in the chute processed on the inner wall of the first box body through the chute processed on the outer wall and the cylinder protruding from the outer wall of the square block. In this way, the vertical plate can be driven to reciprocate by the square block. The reciprocating movement of the vertical plate drives the synchronous movement of a plurality of convex blocks on the left side of the outer wall. The up and down reciprocating movement of the plurality of convex blocks makes the cross bar drive the cross bar to reciprocate left and right in the first box body through the cooperation of the spring. When discharging, the tank body is reversed through the grain pre-treatment discharge structure, and when the grain is blocked, the grain pre-treatment discharge knocking structure continuously knocks on the discharge port to generate vibration, so as to loosen the grain inside for dredging, avoiding the situation in the prior art that the grain is blocked in the discharge pipe and requires the staff to stop the device for manual dredging, thereby improving the working speed.

[0026] Working principle:

[0027] Grain pretreatment drying and stirring work of the rice mill:

[0028] When it is necessary to dry the grain before milling, open the top cover on the feeding port 8, pour the grain into the tank body 6 through the feeding port 8 and close the feeding port 8. Then, connect the external power supply of the third motor 4. The third motor 4 starts to drive the rotating shaft 10 to rotate in the tank body 6 through the bearing. The rotation of the rotating shaft 10 drives the scraper 7 to rotate synchronously through multiple struts to stir the grain. At the same time, connect the external power supply of the heating plate 9. The heating plate 9 starts to energize the internal heating wire to generate heat and transfer it to the tank body 6 to make its interior heat up. In this way, the grain can be stirred by the scraper 7 and the heat is transferred by the heating plate 9 to the tank body 6 to make its interior heat up to dry the grain.

[0029] Grain pretreatment discharging and knocking and dredging work of the rice mill:

[0030] When it is necessary to discharge the dried grain inside the tank body 6, the third motor 4 and the heating plate 9 stop working. Open the top cover on the feeding port 8. Then, connect the external power supply of the second motor 201. The second motor 201 starts to drive the gear 202 to rotate in the straight plate 203 through the bearing. The rotation of the gear 202 drives the tank body 6 to move towards the feed box 5 through the teeth 204, so that the discharging port 8 is driven by the tank body 6 to move downward to correspond to the upper end of the feed box 5. Then, the second motor 202 stops moving. At this time, the grain inside the tank body 6 will flow out through the feeding port 8 into the feed box 5 for collection. When the grain is blocked in the feeding port 8, connect the external power supply of the first motor 102. The first motor 102 starts to drive the drum 103 to rotate in the first box body 101 through the bearing. The rotation of the drum 103 drives the square block 104 to slide up and down reciprocally in the chute processed on the inner wall of the first box body 101 through the chute processed on the outer wall and the cylinder protruding from the outer wall of the square block 104. In this way, the vertical plate 105 can be driven to reciprocate by the square block 104. The reciprocating movement of the vertical plate 105 drives multiple convex blocks 106 on the left side of the outer wall to move synchronously. The up and down reciprocating movement of the multiple convex blocks 106 makes the cross bar 107 drive the cross bar 107 to slide left and right reciprocally in the first box body 101 through the cooperation of the spring 108. (When the convex block 106 jacks up the cross bar 107, the spring 108 will be compressed and when it moves away, the cross bar 107 will be reset by the rebound of the spring 108 to perform reciprocating movement). The reciprocating movement of the cross bar 107 drives the rubber block 109 to continuously impact the outer wall of the feeding port 8 to generate vibration. In this way, the grain blocked in the feeding port 8 can be loosened for dredging work.

[0031] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
