Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing, specifically a crushing device for rice processing agricultural products. Background Technology
[0002] A grain grinding device for agricultural product processing is a mechanical device used to grind or pulverize grains (such as wheat, rice, corn, etc.) into powder or pulverize. It typically consists of a rotating grinding disc and a fixed grinding base. The grain is placed on the disc and ground through the rotation of the disc and friction with the grinding base. Grain grinding devices for agricultural product processing are commonly used in flour production, grain grinding, and food processing. A search revealed Chinese Patent Application No. 202022861103.0, which discloses a wet grain grinding system. The system includes a feeding container, a feeding mechanism, a buffer hopper, a grinding mechanism, and a water supply mechanism. The feeding container stores the grain to be ground for feeding. The feeding mechanism is positioned between the feeding container and the buffer hopper to convey the grain from the feeding container to the buffer hopper. The buffer hopper buffers the grain conveyed by the feeding mechanism, and the grain falls from the buffer hopper into the grinding mechanism. The grinding mechanism is positioned below the buffer hopper for wet grinding the grain to obtain a grain slurry. The water supply mechanism is positioned above the grinding mechanism to provide the water required for wet grinding.
[0003] The technical features in the aforementioned comparative documents involve a feeding mechanism to transport materials. However, due to the large volume of agricultural products, the processing equipment is all in the ton range, with large size and high feeding ports. Currently, the feeding ports of rice crushing devices used for agricultural product processing are all located on the top of the machine. Setting up a conveying device would be too large, taking up too much space, making it difficult to retract and move, and inconvenient for transportation. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a crushing device for rice processing in order to solve the technical problem that the conveying device occupies too much space and is difficult to transport.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice crushing device for agricultural product processing, comprising a first conveyor belt shell, a second conveyor belt shell, a conveyor belt, a front cover, a transmission mechanism, and a housing. The transmission mechanism includes a motor, one end of which is provided with transmission teeth. A rotating ring is provided on the back of the housing, and a fixing rod is provided on one side of the rotating ring.
[0006] By adopting the above technical solution, when grinding, pulling down the handle causes the lever to slide on the arc-shaped structure at the lower end of the pawl, thereby causing the pawl to rotate and disengage from the ratchet gear. Afterward, the ratchet rotates normally, causing the first conveyor belt shell to slide on the housing. When it is necessary to retract, first pulling up the handle causes the handle to rotate the fixing rod, which then causes the first conveyor belt shell to slide on the housing. The first and second conveyor belt shells rotate relative to each other around the ratchet shaft, reducing the space required for storage and transportation. The ratchet and pawl have arcs at their top ends to reduce the resistance to opening and closing, making operation simple and reducing the learning cost.
[0007] Furthermore, the front cover is rotatably connected to the housing via a hinge, and the front cover is fixed to the housing via a latch and screws. The front cover has a circular shape.
[0008] By adopting the above technical solution, the replacement time is reduced, the structure is reliable, and maintenance is convenient.
[0009] Furthermore, the first conveyor belt shell is rotatably connected to the second conveyor belt shell via a ratchet shaft, and both the first and second conveyor belt shells are made of stainless steel.
[0010] By adopting the above technical solution, the manufacturing difficulty of the first conveyor belt shell and the second conveyor belt shell is reduced.
[0011] Furthermore, the top of the fixing rod is rotatably connected to the first conveyor belt shell and the second conveyor belt shell via a ratchet shaft, which is made of 40Cr material.
[0012] By adopting the above technical solution, the conveying mechanism can be easily put away and put down.
[0013] Furthermore, a pawl is engaged on one side of the ratchet shaft, and the pawl is rotatably connected to the rotating ring via the shaft. The bottom end of the pawl has an arc-shaped structure.
[0014] By adopting the above technical solution, the conveyor belt mechanism can automatically lock when it is retracted.
[0015] Furthermore, a lever is slidably connected to the bottom end of the pawl, and a lever is provided inside the lower part of the fixed rod. The top end of the lever abuts against the arc surface of the bottom end of the fixed rod, and a handle is provided in the middle of the lever.
[0016] By adopting the above technical solution, the conveyor belt mechanism can be easily raised and lowered by simply turning the handle.
[0017] Furthermore, the motor is electrically connected to an external power source, and multiple transmission teeth are provided, with belts mounted on the multiple transmission teeth.
[0018] By adopting the above technical solution, only one motor is needed to drive all structural movements.
[0019] In summary, the present invention has the following main advantages:
[0020] 1. This utility model uses a ratchet, pawl, and handle. When grinding, pulling the handle downwards causes the lever to slide on the arc-shaped structure at the lower end of the pawl, thereby causing the pawl to rotate and disengage from the ratchet gear. Afterwards, the ratchet rotates normally, causing the first conveyor belt shell to slide on the housing. When it is necessary to retract, first pull the handle upwards, then the handle causes the fixing rod to rotate, and then the fixing rod causes the first conveyor belt shell to slide on the housing. The first and second conveyor belt shells rotate relative to each other around the ratchet shaft, reducing the space required for storage and transportation. The ratchet and pawl have arcs at their top ends to reduce the resistance to opening and closing, making operation simple and improving the convenience of operation.
[0021] 2. This utility model uses a shell, a housing, a hinge, and a latch. When grinding is required, the front cover is closed first, and then the screws are tightened. When cleaning is required, the screws are unscrewed first, and then the inner wall of the housing is cleaned with a brush. When maintenance and replacement of the grinding head are required, the front cover is opened first, and then the replacement is carried out with tools. This reduces the time required for replacement, and the structure is reliable and convenient for maintenance. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0028] The embodiments of this utility model will be described below based on its overall structure.
[0029] A rice crushing device for agricultural product processing, such as Figures 1-4 As shown, the system includes a first conveyor belt shell 1, a second conveyor belt shell 2, a conveyor belt 3, a front cover 5, a transmission mechanism 6, and a housing 14. The transmission mechanism 6 includes a motor 601, one end of which is provided with a transmission gear 602. A rotating ring 8 is provided on the back of the housing 14, and a fixed rod 13 is provided on one side of the rotating ring 8. When grinding, the handle 12 is pulled down, and then the handle 12 drives the lever 9 to slide on the arc-shaped structure at the lower end of the pawl 10, thereby causing the pawl 10 to rotate and disengage from the gear of the ratchet 13. Afterward, the ratchet 13 rotates normally, causing the first conveyor belt shell 1 to slide on the housing 14. When retracting, the handle 12 is pulled to drive the fixed rod 13 to rotate, and then the fixed rod 13 drives the first conveyor belt shell 1 to slide on the housing 14. The first and second conveyor belt shells rotate relative to each other around the ratchet shaft 13, reducing the space required for storage and transportation. The tops of the ratchet 13 and the pawl 10 are provided with arcs to reduce the resistance to opening and closing and improve the convenience of operation.
[0030] See Figure 1 , Figure 2 , Figure 3 The front cover 5 is rotatably connected to the housing 14 via a hinge 7, and the front cover 5 is threadedly fixed to the housing 14 via a latch 4. The front cover 5 has a circular shape, which improves the overall stability of the structure.
[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first conveyor belt shell 1 is rotatably connected to the second conveyor belt shell 2 via a ratchet shaft 15. Both the first conveyor belt shell 1 and the second conveyor belt shell 2 are made of stainless steel, which improves the manufacturing speed.
[0032] See Figure 4 The top of the fixed rod 13 is rotatably connected to the first conveyor belt shell 1 and the second conveyor belt shell 2 via a ratchet shaft 15. The ratchet shaft 15 is made of 40Cr material to reduce the friction of the take-up and take-down mechanism.
[0033] See Figure 4 A pawl 10 is engaged on one side of the ratchet shaft 15. The pawl 10 is rotatably connected to the rotating ring 8 via the shaft. The bottom end of the pawl 10 has an arc-shaped structure to prevent the structure from automatically loosening after being retracted.
[0034] See Figure 4The bottom end of the pawl 10 is slidably connected to a lever 9. The lever 9 is located inside the lower part of the fixed rod 13. The top end of the lever 9 abuts against the arc surface of the bottom end of the fixed rod 13. A handle 12 is located in the middle of the lever 9 to facilitate the operator to use the handle to load and unload the conveyor belt mechanism.
[0035] The implementation principle of this embodiment is as follows: First, when grinding, pull down the handle 12, and then the handle 12 drives the lever 9 to slide on the arc-shaped structure at the lower end of the pawl 10, thereby causing the pawl 10 to rotate and disengage from the teeth of the ratchet 13. After that, the ratchet 13 rotates normally, driving the first conveyor belt shell 1 to slide on the housing 14. When it is necessary to retract, first pull up the handle 12, and then the handle 12 drives the fixing rod 13 to rotate. Then the fixing rod 13 drives the first conveyor belt shell 1 to slide on the housing 14. The first conveyor belt shell 1 and the second conveyor belt shell 2 rotate relative to each other around the ratchet shaft, reducing the space required for storage and transportation. When grinding is required, first close the front cover 5, and then tighten the screws. When cleaning is required, first unscrew the screws, and then clean the inner wall of the housing 14 with a brush. When repairing and replacing the grinding head is required, first open the front cover 5, and then replace it with tools, reducing the replacement time. The structure is reliable and easy to maintain.
