Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] This utility model provides a polishing device for rice processing. Please refer to [link / reference]. Figure 1-3 The system includes a frame 1, a feeding hopper 2 fixedly mounted on the top of the frame 1, a transmission mechanism mounted on the frame 1, and a polishing mechanism mounted on the frame 1. The polishing mechanism includes a polishing cylinder 15, which has an inlet hopper 16 and an outlet hopper 17. Figure 1 As shown, the feeding hopper 2 is located directly above the feeding hopper 16. Both the feeding hopper 16 and the discharging hopper 17 are equipped with gates. By opening the gates, materials can be fed in and discharged. The feeding hopper 16 and the discharging hopper 17 are symmetrical about the polishing cylinder 15, and a counterweight structure is installed on the outer wall of the polishing cylinder 15. The front and rear ends of the frame 1 are both hinged to door panels 8.

[0030] Under the action of the counterweight structure, after the polishing cylinder 15 stops, the feed hopper 16 and the discharge hopper 17 are located at the top and bottom respectively, and the material is discharged from the discharge hopper 17.

[0031] The polishing cylinder 15 is rotatably connected to the frame 1 at both ends via bearings. Specifically, a bearing seat 14 is fixedly installed at the left end of the frame 1, and the left end of the polishing cylinder 15 is rotatably connected to the bearing seat 14 via a bearing. The right end of the polishing cylinder 15 is driven by a first servo motor 3. Specifically, a drive gear 12 is fixedly installed on the output shaft of the first servo motor 3, and the drive gear 12 meshes with a driven gear 13. The driven gear 13 is fixedly installed at the right end of the polishing cylinder 15. The polishing cylinder 15 is driven to rotate by the first servo motor 3 to polish the rice.

[0032] The transmission mechanism includes a U-shaped support plate 9 fixedly installed on the frame 1. The two ends of the U-shaped support plate 9 are respectively rotatably connected to the conveyor rollers 10 through bearings. The two conveyor rollers 10 are connected by a conveyor belt 11. The right conveyor roller 10 is connected to the second servo motor 4.

[0033] The output shaft of the second servo motor 4 is fixedly mounted with an active synchronous pulley 5, and the right-side conveyor roller 10 is fixedly mounted with a driven synchronous pulley 6. The active synchronous pulley 5 and the driven synchronous pulley 6 are connected by a synchronous belt 7.

[0034] The counterweight structure includes an arc-shaped block 18 welded to the polishing cylinder 15, a counterweight block 19 mounted on the arc-shaped block 18, and the counterweight block 19 and the arc-shaped block 18 are welded together.

[0035] In practical use:

[0036] like Figure 1 As shown, rice is injected into the feeding hopper 2 at this time. After falling into the feeding hopper 16, the rice enters the polishing cylinder 15. The first servo motor 3 is started to drive the polishing cylinder 15 to rotate in order to achieve the polishing operation of the rice.

[0037] After polishing is completed, the first servo motor 3 stops working, and under the gravity of the arc-shaped block 18 and the counterweight block 19, as... Figure 1 As shown, at this time, the feed hopper 16 and the discharge hopper 17 are located above and below respectively. The gate inside the discharge hopper 17 is opened, allowing the rice in the polishing cylinder 15 to fall onto the conveyor belt 11. The second servo motor 4 drives the conveyor belt 11 to transport the rice.

[0038] Example 2:

[0039] See attached document Figure 4 Unlike embodiment 1, the arc block 18 has a T-shaped groove 181, and the counterweight block 19 has a T-shaped slider 191 welded on it. The inner wall of the T-shaped groove 181 is slidably connected to the T-shaped slider 191.

[0040] In practical use:

[0041] like Figure 1 As shown, rice is injected into the feeding hopper 2 at this time. After falling into the feeding hopper 16, the rice enters the polishing cylinder 15. The first servo motor 3 is started to drive the polishing cylinder 15 to rotate in order to achieve the polishing operation of the rice.

[0042] After polishing is completed, the first servo motor 3 stops working, as follows: Figure 1 As shown, the counterweight 19 is slidably connected to the arc-shaped block 18. At this time, the feed hopper 16 and the discharge hopper 17 are located above and below respectively. The gate inside the discharge hopper 17 is opened, so that the rice in the polishing cylinder 15 falls onto the conveyor belt 11. The second servo motor 4 drives the conveyor belt 11 to transport the rice.
