[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of a hopper body, a support frame, a hopper, a metering cylinder, an extension arm, a directional control arm, and a coupling motor, pours a certain amount of rice to be screened into the hopper. The coupling motor drives the directional control arm to rotate on the support frame, so that the extension arm moves inside the directional control arm and rotates downward, moving the metering cylinder downward to the bottom so that its bottom extends out of the hopper. At this time, the rice between the two cones of the metering cylinder and the inner wall of the hopper falls downward, improving the metering effect of the equipment.
[0015] 2. This utility model, through the setting of a hopper body, a support frame, a vibrating motor, a vibrating paddle shaft, a vibrating support frame, a convex screen, a concave screen, and a top frame spring, uses a vibrating motor to drive the rotation of the vibrating paddle shaft on the support frame, which causes the vibrating support frame to vibrate on the hopper body through the top frame spring. This causes the rice falling into the convex screen to be initially screened, and some rice falls into the concave screen at the lower end for further screening with different apertures. The setting of the convex and concave screens increases the rice screening area and improves the screening efficiency of the device.
[0016] 3. This utility model, through the setting of a hopper body, baffle plate and baffle plate, allows the final product to fall into the bottom of the hopper body after screening. The bottom of the hopper body is inclined, so that the finished rice always gathers on one side of the baffle plate. The baffle plate can be rotated by the connecting shaft to avoid contact with the baffle plate. The baffle plate can also be moved to the leftmost end in the slide, so that the rice in the hopper body pours out and is collected, improving the collection effect of the equipment.

[0022] 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.
[0023] The embodiments of this utility model will be described below based on its overall structure.
[0024] Please see Figure 1-4 A rice processing screening machine with a quantitative feeding structure includes a hopper body 1, a support frame 2 installed on the upper end of the hopper body 1, a hopper 3 installed on one end of the support frame 2, a limiting rod hole 4 opened on one end of the support frame 2, a quantitative cylinder 5 installed in the middle of the limiting rod hole 4, a rod placement hole 6 opened on the upper end of the quantitative cylinder 5, an extension arm 7 installed on one end of the rod placement hole 6, a directional control arm 8 installed on the outer end of the extension arm 7, and a coupling motor 9 installed at the front end of the directional control arm 8. The extension arm 7 and the quantitative cylinder 5 form a telescopic structure through the rod placement hole 6, and the quantitative cylinder 5 and the hopper 3 are connected through the limiting rod hole 4. The system forms a sliding structure. The directional control arm 8 is connected to the support frame 2 via a coupling motor 9 to form a rotating structure. The metering cylinder 5 is connected to the hopper 3 via the directional control arm 8 to form a telescopic structure. A certain amount of rice to be screened is poured into the hopper 3. The directional control arm 8 is driven to rotate on the support frame 2 by the coupling motor 9, so that the extension arm 7 moves inside the directional control arm 8 and rotates downward, moving the metering cylinder 5 downward to the bottom so that its bottom extends out of the hopper 3. At this time, the rice between the two cones of the metering cylinder 5 and the inner wall of the hopper 3 falls downward, improving the metering effect of the equipment.
[0025] Please see Figure 1-4A rice processing screening machine with a quantitative feeding structure includes a vibrating motor 10 installed in the middle of a support frame 2, a vibrating paddle shaft 11 installed at one end of the vibrating motor 10, a vibrating support frame 12 installed at one end of the vibrating paddle shaft 11, an upper sliding groove 13 opened at the inner end of the vibrating support frame 12, a convex screen 14 installed at the inner end of the upper sliding groove 13, a lower sliding groove 15 opened at the inner end of the vibrating support frame 12, a concave screen 16 installed at the inner end of the lower sliding groove 15, a limiting screen plate 17 installed at one end of the vibrating support frame 12, and a top frame spring 18 installed at the lower end of the vibrating support frame 12. The vibrating paddle shaft 11 is movably connected to the vibrating support frame 12, and the vibrating support frame 12 is connected to the top frame spring 18. Spring 18 and the main body 1 of the hopper form a telescopic structure. The convex screen 14 and the vibrating support frame 12 form a sliding structure through the upper sliding groove 13. The concave screen 16 is engaged with the vibrating support frame 12 through the screen limiting plate 17. The vibrating motor 10 drives the vibrating paddle shaft 11 to rotate on the support frame 2, so that the vibrating support frame 12 vibrates on the main body 1 of the hopper through the top frame spring 18. This causes the rice falling into the convex screen 14 to be initially screened. Some of the rice falls into the concave screen 16 at the lower end and is screened again with different apertures. The setting of the convex screen 14 and the concave screen 16 increases the rice screening area and improves the screening efficiency of the device.
[0026] Please see Figure 1-4 A rice processing screening machine with a quantitative feeding structure is disclosed. A connecting shaft 19 is installed at one end of the hopper body 1, and a baffle plate 20 is installed at the outer end of the connecting shaft 19. A slide 21 is opened at the inner end of the hopper body 1, and a baffle plate 22 is installed at the inner end of the slide 21. The baffle plate 20 and the hopper body 1 form a rotating structure via the connecting shaft 19, and the baffle plate 22 and the hopper body 1 form a sliding structure via the slide 21. The final screened product falls to the bottom of the hopper body 1. The bottom of the hopper body 1 is inclined, so that the finished rice always gathers on one side of the baffle plate 22. The baffle plate 20 can be rotated via the connecting shaft 19 to prevent it from contacting the baffle plate 22, and the baffle plate 22 can be moved to the leftmost end within the slide 21, causing the rice in the hopper body 1 to pour out and be collected, thus improving the collection efficiency of the equipment.
[0027] Working principle: During use, a certain amount of rice to be screened is first poured into the hopper 3. The coupling motor 9 drives the control arm 8 to rotate on the support frame 2, causing the extension arm 7 to move inside the control arm 8 and rotate downward, moving the metering cylinder 5 to its lowest point so that its bottom extends out of the hopper 3. At this time, the rice between the two cones of the metering cylinder 5 and the inner wall of the hopper 3 falls downward. At the same time, the vibration motor 10 is started to drive the vibration paddle shaft 11 to rotate on the support frame 2, causing the vibration support frame 12 to vibrate on the hopper body 1 through the top frame spring 18, so that the rice falling into the convex screen 14 is initially screened, and some rice falls into the lower part. The concave screen 16 performs secondary sieving with different aperture sizes. The arrangement of the convex screen 14 and the concave screen 16 increases the sieving area of the rice. The final sieving product falls into the bottom of the hopper body 1. The bottom of the hopper body 1 is inclined, so that the finished rice always gathers on one side of the baffle plate 22. The baffle plate 20 can be rotated through the connecting shaft 19 to prevent it from contacting the baffle plate 22. The baffle plate 22 can also be moved to the leftmost end in the slide 21, causing the rice in the hopper body 1 to pour out. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
