Rice processing and conveying device

Abstract

The invention relates to the technical field of rice processing equipment, and discloses a rice processing and conveying device. The rice processing and conveying device comprises a fixed bottom plate, supporting frames are installed on the two sides of the upper end of the fixed bottom plate, conveying rollers are installed at the top ends of the supporting frames, a conveying belt is wound between the conveying rollers, a screening groove is formed in the lower end of the upper-layer conveying belt, a material falling groove is formed in the middle of the lower-layer conveying belt, the twosides of the lower end of the material falling groove are fixed to the upper end of the fixed bottom plate through material falling frames, a material falling box is installed at the lower end of thematerial falling groove, a driving shaft is installed at the bottom end inside the material falling box, a driving gear is installed in the middle of the right end of the driving shaft, a driven gearis meshed with the upper end of the driving gear, a rotating shaft is installed at the upper end of the driven gear, a material falling shaft is clamped inside the upper end of the rotating shaft, andthe top end of the material falling shaft penetrates through the material falling box to be provided with a material falling plate. According to the rice processing and conveying device, broken riceblocked inside the conveying holes in the conveying belt is efficiently guided out, the screening efficiency during conveying is improved, meanwhile, intermittent movement of the conveying belt is achieved, and the screening and conveying effect is further ensured.

Description

technical field [0001] The invention relates to the technical field of rice processing equipment, in particular to a rice processing transmission device. Background technique [0002] Rice (Rice) is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also The main food of people in most parts of China. [0003] The principle of the rice hulling machine is to use a pair of rubber rollers that do not rotate in the same direction, and the pressure of the weight to break and rub the rice passing through the rollers to achieve the purpose of hulling. When the husked material passes through the chaff separation chamber, it is acted by the wind force, and the paddy-grass mixture is separated from the rice husk. The rice huller is a grain processing machine that removes the chaff from rice and makes it into brown rice. ...

Problems solved by technology

[0004] In the prior art, for freshly husked rice, some are sieved manually, which is less efficient and the sieving effect is not good, and some are sieved mechanically. The sieve is driven by mechanical equipment to shake the rice sieve, simulating manual sieving. This method is a separate process for rice sieving, resulting in increased processing costs.

Chinese patent (publication number: CN210846490U) discloses a rice processing conveying device, including a first conveying roller and a second conveying roller connected to the first conveying roller through a conveyor belt socket. The upper and lower double-layer structure is formed between the conveying rollers. The conveying belt is provided with evenly distributed drop holes, the protective laminates are arranged on both sides of the conveying belt, and the receiving plate is arranged between the two conveying belts, and the upper conveying belt The bottom is rotated and installed with paddles. Although this device can realize the screening function of the shelled rice during transmission to a certain extent, in actual operation, the falling holes on the conveyor belt in this device are easy to be damaged during the transmission process. clogging occurs, therefore, further improvement is required
