Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a processing device for precisely controlling the amount of rice processed. Background Art

[0002] Rice processing equipment is the equipment used in a series of rice processing procedures. Through a series of processing procedures such as shelling and screening, rice can be better consumed by people. Currently, the rice input into the processing equipment is either manually over-invested or scattered, and neither can control the input amount of rice.

[0003] In view of the above problems, the existing patent (Publication No.: CN213791783U) proposed a rice processing device that can precisely control the amount of rice processed. When the raw material reaches the specified amount, the weighing plate transmits a signal to the single-chip microcomputer inside the control panel, and the single-chip microcomputer controls the electric telescopic rod to work, so that the whole mounting plate moves downward to send out the rice.

[0004] However, the above-mentioned rice processing device has the following problems when controlling the amount of rice processed: when determining the required weight of rice, during the process of putting rice into the weighing plate, the staff cannot stop sending out the rice in time when reaching the specified weight. Therefore, this process will still cause the weight of the rice to exceed, and the pouring speed of the rice is uncontrollable. Therefore, the specific exceeded amount cannot be determined, resulting in poor accuracy of the rice weight. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a processing device for precisely controlling the amount of rice processed to solve the technical problems mentioned in the above background art.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0036] Please refer to Figures 1-4 , the present utility model provides a technical solution: a processing device for precisely controlling the rice processing amount, including: support columns 2, a bottom plate 1, an annular fixing plate 7, and a top plate 9. The bottom plate 1 and the annular fixing plate 7 are fixedly sleeved on the support columns 2 in sequence from bottom to top in the vertical direction, and the top plate 9 is fixedly sleeved on the support columns 2. The hopper 12 is of a funnel-shaped structure, the bottom diameter of the hopper 12 is smaller than the feeding hole 801, the bottom of the hopper 12 is in smooth contact with the annular movable plate 8, and is fixedly connected to the top plate 9 through a semi-open annular connecting plate 11. The annular movable plate 8 is rotatably arranged on the middle hole of the annular fixing plate 7. An annular track 701 is provided on the annular fixing plate 7. A plurality of rollers 19 that are in rolling cooperation with the annular track 701 are rotatably installed at the bottom of the annular movable plate 8. A fixed column 16 is fixedly connected to the middle of the bottom plate 1. A connecting frame 13 is fixedly connected to the middle hole of the annular movable plate 8. A stepping motor 3 is fixedly installed on the fixed column 16. The output shaft of the stepping motor 3 is fixedly connected to the connecting frame 13. Four groups of feeding holes 801 arranged in an annular array are provided on the annular movable plate 8. The hopper 12 is aligned with the feeding holes 801. Four groups of trays 5 are provided, corresponding to the feeding holes 801 one by one. A weighing sensor 18 is embedded in the middle of the tray 5. The weighing sensor 18 is communicatively connected to the stepping motor 3. The weighing sensor 18 detects the weight data of the rice in the rice bucket 6 and transmits it to the single-chip microcomputer. The single-chip microcomputer can control the stepping motor 3. The rice bucket 6 is arranged on the tray 5. A conveyor belt 14 is arranged above the annular fixing plate 7. The output end of the conveyor belt 14 is connected to the hopper 12. The rice is fed into the hopper 12 through the conveyor belt 14. The rice slides down along the hopper 12 and falls into the rice bucket 6 through the feeding holes 801. After the single-chip microcomputer detects that the weight of the rice monitored by the weighing sensor 18 reaches the set value, it controls the stepping motor 3 to drive the connecting frame 13 to drive the annular movable plate 8 to rotate counterclockwise by 45° and then stop. The bottom end of the hopper 12 contacts the solid part of the annular movable plate 8 to block the hopper 12. Then, the tray 5 is driven to drive the rice bucket 6 to move radially outward along the bottom plate 1 to facilitate taking out the rice in the rice bucket 6. After taking out the rice, the tray 5 drives the rice bucket 6 to reset, and the stepping motor 3 rotates clockwise by 45° to reset. The rice continues to be fed through the hopper 12, and the above operations are repeated. This device stops the rice from continuing to fall into the rice bucket 6 in time after the rice reaches the set weight, avoiding overweight of the rice in the rice bucket 6 and improving the weighing accuracy.

[0037] Specifically, as Figure 2 andFigure 4 As shown in the figure, sliding grooves 501 are formed on both sides of the bottom of the tray 5. Guide blocks 4 that are slidably engaged with the sliding grooves 501 are fixedly connected to the bottom plate 1. An electric push rod 17 is fixedly installed on the fixed column 16, and the push rod end of the electric push rod 17 is fixedly connected to the tray 5. After loading the rice with the set weight, the tray 5 is pushed out by the push rod end of the electric push rod 17, which facilitates the taking and placing of the rice bucket 6.

[0038] Specifically, as Figure 2 shown in the figure, a driving motor 10 is fixedly installed on the top plate 9. The output shaft of the driving motor 10 is drivingly connected to a spiral auger 15 that is adapted to the hopper 12. When the rice is discharged through the hopper 12, the spiral auger 15 is driven to rotate by the driving motor 10, which can not only prevent the rice from piling up but also accelerate the discharging of the rice and improve the discharging speed.

[0039] Working principle: During use, the rice is fed into the hopper 12 through the conveyor belt 14. The spiral auger 15 is driven to rotate by the driving motor 10, which can not only prevent the rice from piling up but also accelerate the discharging of the rice and improve the discharging speed. The rice falls along the hopper 12 and falls into the rice bucket 6 through the discharging hole 801. After the single-chip microcomputer determines that the weight of the rice monitored by the weighing sensor 18 reaches the set value, it controls the stepping motor 3 to drive the connecting frame 13 to drive the annular movable plate 8 to rotate counterclockwise by 45° and then stop. The bottom end of the hopper 12 contacts the solid part of the annular movable plate 8 to block the hopper 12. After that, the tray 5 is pushed out by the push rod end of the electric push rod 17, which facilitates the taking and placing of the rice bucket 6. When the rice bucket 6 is taken and placed, it is convenient to take out the rice in the rice bucket 6. After taking out the rice, the tray 5 drives the rice bucket 6 to reset, and the stepping motor 3 rotates clockwise by 45° to reset. The rice continues to be discharged through the hopper 12. By repeating the above operations, the device can timely stop the rice from continuing to fall into the rice bucket 6 after the rice reaches the set weight, prevent the rice in the rice bucket 6 from being overweight, and improve the weighing accuracy.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
