Description

Technical Field

[0001] The utility model belongs to the field of rice processing, and in particular relates to a feeding mechanism for a rice polishing machine. Background Art

[0002] Polishing machines are also called grinders, and are often used for mechanical grinding, polishing and waxing. The working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the combined effect of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. Now, when processing rice, polishing machines are also used to remove impurities on the surface of rice.

[0003] The Chinese utility model patent is CN220345917U, which discloses a feeding mechanism of a rice polisher, including: a discharging barrel, the discharging barrel is a circular structure, and a feeding pipe is welded downward at the bottom center of the discharging barrel, and a flange is welded at the bottom of the feeding pipe, and the feeding mechanism is fixed to the feeding port of the rice polisher through the flange; a blocking plate is welded on the top opening of the feeding pipe, and a motor is fixed at the center of the cross positioning frame by screw locking; a driving shaft is rotatably installed at the bottom center of the motor, and through the driving shaft, the motor can rotate to drive the two rectangular discharging troughs on the rotating disk to rotate and intermittently overlap with the two rectangular feeding troughs on the blocking plate to discharge materials, automatically limit the discharge flow of the feeding pipe, and reduce the frequency of blockage of the rice polisher;

[0004] The above design can automatically control the speed of rice delivery at the polisher's feed port by setting the cooperation between the paddle plate and the paddle disk, and prevent the feed port from being partially blocked.

The present invention provides the following embodiments.

[0030] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a feeding mechanism for a rice polishing machine comprises an outer cylinder 1, a top cover 2, a feeding port 3 and a conveying port 4. The top cover 2 is provided at the top opening of the outer cylinder 1, the feeding port 3 is provided at the bottom end of the outer cylinder 1, the conveying port 4 is fixedly installed on the side of the outer cylinder 1, and a feeding mechanism 5 is rotatably installed inside the outer cylinder 1. The feeding mechanism 5 comprises a protective shell 51, a driving motor 52, a driving rod 53 and a spiral blade 54. The protective shell 51 is fixedly installed on the surface of the top cover 2, the driving motor 52 is fixedly installed inside the protective shell 51, the driving rod 53 is fixedly installed at the output end of the driving motor 52, and the spiral blade 54 is fixedly installed outside the driving rod 53. The feeding mechanism 5 is used for stably conveying the material inside the outer cylinder 1, and fixing mechanisms 6 are symmetrically fixedly installed on both sides of the top cover 2. The fixing mechanism 6 is used for quickly opening and closing the top cover 2, and a closing mechanism 7 is rotatably installed at the bottom end of the top cover 2. The closing mechanism 7 is used to control the closing or opening of the opening of the conveying port 4.

[0031] During use, the device is placed at the target position, and then the top cover 2 is installed on the top of the outer cylinder 1. The connection between the outer cylinder 1 and the top cover 2 is further strengthened by using the fixing mechanism 6. Then, the rice is poured into the outer cylinder 1 by using the closing mechanism 7 and the conveying port 4. Finally, the internal rice is stably conveyed by using the feeding mechanism 5. By starting the driving motor 52, the driving rod 53 itself rotates, and the spiral blade 54 is kept in close contact with the inner wall of the feed port 3 and continuously rotates to push the rice inside the outer cylinder 1, so that the material can stably enter the bottom end of the feed port 3 to prevent the rice from being blocked inside the outer cylinder 1.

[0032] By the attached Figure 4As shown, in this embodiment, the overall radius of the spiral blade 54 is consistent with the inner diameter of the feed port 3 itself, so that the spiral blade 54 can stably rotate inside the feed port 3. During use, the specifications of the spiral blade 54 are limited to ensure that the spiral blade 54 can be tightly attached to the inner wall of the feed port 3 and stably push the material inside the outer cylinder 1.

[0033] By the attached Figure 4 As shown, in this embodiment, the driving rod 53 and the driving motor 52 are connected by a reinforcing screw and a reinforcing nut for quickly completing the combination of the components. During use, the driving rod 53 and the spiral blade 54 can be quickly replaced according to the different diameters of the feed port 3, which is also convenient for subsequent maintenance and adjustment.

[0034] By the attached Figure 5 As shown, in this embodiment, the fixing mechanism 6 includes a plug-in block 61, a side connecting plate 62, a fixing screw groove 63, a fixing screw 64 and a fixing nut 65. The plug-in block 61 is fixedly installed on the side of the top cover 2, the side connecting plate 62 is fixedly installed on the side of the outer tube 1, the plug-in block 61 and the side connecting plate 62 are slidably plugged in, and the side connecting plate 62 and the plug-in block 61 are jointly provided with a fixing screw groove 63, the fixing screw 64 is rotatably installed in the fixing screw groove 63, and the fixing nut 65 is threadedly installed at the bottom end of the fixing screw 64.

[0035] During use, the top cover 2 is installed to the top opening of the outer tube 1, and then the plug-in block 61 is inserted into the side connecting plate 62. Thereafter, the connection between the top cover 2 and the outer tube 1 is further strengthened by the cooperation of the fixing screw 64 and the fixing nut 65 to ensure the stability of the connection between the outer tube 1 and the top cover 2.

[0036] By the attached Figure 5 As shown, in this embodiment, the surface of the top cover 2 is symmetrically fixed with lifting rings for assisting the top cover 2 to move up and down. During use, the setting of the lifting rings facilitates the movement and adjustment of the positions of the top cover 2 and various components on the surface.

[0037] By the attached Figure 6 As shown, in this embodiment, the closing mechanism 7 includes a bracket 71, a rotating frame 72, a rotating baffle 73 and an input slot 74. The bracket 71 is symmetrically fixedly installed on one side of the bottom end of the top cover 2, the rotating frame 72 is rotatably installed between the brackets 71, the rotating baffle 73 is fixedly installed on the outside of the rotating frame 72, and the delivery port 4 and the inner part of the outer tube 1 are jointly provided with an input slot 74.

[0038] During use, the rice is poured into the input groove 74 inside the conveying port 4, and the rice rolls stably into the outer cylinder 1 through the input groove 74. During the rolling process of the rice, the rice pushes the rotating baffle 73, causing the rotating baffle 73 to deflect around the rotating frame 72, allowing the rice to stably enter the outer cylinder 1. When the pouring of the rice stops, the rotating baffle 73 will automatically return to its original position, closing the input groove 74 and the interior of the conveying port 4 to prevent external impurities from entering the outer cylinder 1.

[0039] By the attached Figure 6 As shown, in this embodiment, counterweights are symmetrically fixedly installed on the bottom ends of both sides of the rotating baffle 73, and the rotating baffle 73 is made of plastic to stably control the opening and closing of the input slot 74. During use, the center of gravity of the rotating baffle 73 can be ensured to be biased toward the lower end, and the rotating baffle 73 can automatically return to its original position after being pushed and automatically deflected.

[0040] By the attached Figure 3 As shown, in this embodiment, a sealing block is fixedly installed at the bottom end of the top cover 2, and the sealing block is slidably plugged into the top opening part of the outer cylinder 1 to ensure the stability of the connection between the outer cylinder 1 and the top cover 2. During use, the installation of the sealing block makes the connection between the outer cylinder 1 and the top cover 2 tighter.
