Description

Technical Field

[0001] The utility model relates to the field of feeding devices, in particular to a rice processing sieve feeding device. Background Art

[0002] Rice processing is a delicate art. From rice grains to crystal rice, every step embodies the wisdom of craftsmen. First, the rice grains are cleaned to remove impurities and ensure the purity of the raw materials. Then, the rice grains enter the rice husker to remove the husks and reveal the crystal brown rice. Then, the brown rice passes through a fine rice mill to remove the rice bran and retain the purest endosperm. During the rice milling process, the machine will precisely control the force to ensure that the rice is intact and has less broken rice. Finally, after color sorting and polishing, the rice becomes white and translucent, exuding an attractive rice aroma. During the processing of rice, a feeding device is often required to connect the previous process and the next process, so as to use the feeding device to transport the rice. In the existing patent application with application number CN202120862466.8, a precise feeding mechanism for rice processing is proposed. Since rice is often mixed with debris, and the feeding mechanism is not provided with a screening component, the rice and the debris mixed therein will be fed and transported together by the feeding mechanism, which will easily block the feeding mechanism on the one hand, and reduce the efficiency of rice processing on the other hand. Therefore, a rice processing screening feeding device is needed to solve the above problems. Summary of the invention

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a connecting corrugated hose 3 is installed at the upper end of the feed hopper 2, and the connecting corrugated hose 3 is fixedly connected to the rectangular pipe 8 on the screening component 4. The upper end of the connecting corrugated hose 3 is installed with the screening component 4, and the screening component 4 is composed of a rectangular pipe 8, a conical pipe 9, a screening net 10 and a vibration motor 11. The conical pipe 9 is installed at the upper end of the rectangular pipe 8, and the screening net 10 is installed on the inner wall of the rectangular pipe 8. There are two vibration motors 11 and they are symmetrically installed on the outer wall of the rectangular pipe 8. The rectangular pipe 8 on the screening component 4 is fixedly connected to the conical pipe 9, the screening net 10 and the vibration motor 11. Four elastic support structures 5 are symmetrically installed on the outer wall of the rectangular pipe 8 and the feed hopper 2. The elastic support structure 5 is composed of a support spring 12 and a mounting connection bracket 13. There are two mounting connection brackets 13 and they are respectively installed at the upper and lower ends of the support spring 12 The supporting spring 12 on the elastic supporting structure 5 is fixedly connected to the two mounting and connecting brackets 13, and the upper mounting and connecting bracket 13 is fixedly connected to the rectangular pipe 8 on the screening assembly 4, and the lower mounting and connecting bracket 13 is fixedly connected to the feed hopper 2. By arranging the screening assembly 4 above the feed hopper 2 and arranging the elastic supporting structure 5 to connect the feed hopper 2 with the screening assembly 4, when the rice is discharged and transported, the rice can enter the spiral feeder body 1 through the screening assembly 4. At this time, the screening assembly 4 can block and screen out larger debris mixed in the rice, thereby reducing the probability of the spiral feeder body 1 being blocked, and at the same time improving the efficiency of rice feeding and transportation.

At this time, the vibration motor 11 will vibrate the rectangular pipe 8, the conical pipe 9 and the screening net 10, and the support spring 12 on the elastic support structure 5 will enhance the vibration of the screening component 4. Then, the rice that falls into the screening component 4 will pass downward through the mesh on the screening net 10 after being vibrated, and then the rice will pass downward from the connecting corrugated hose 3 and the feed hopper 2 in turn, and finally the rice will fall into the spiral feeder body 1, and then the rice will be transported by the spiral feeder body 1, and finally the rice will slide out of the feeding pipe 6; and the larger debris mixed in the rice will be blocked by the screening net 10, thereby preventing the larger debris from entering the spiral feeder body 1, thereby reducing the probability of the spiral feeder body 1 being blocked.
