Description

Technical Field

[0001] The utility model relates to the technical field of rice color sorters, especially rice color sorters. Background Art

[0002] The existing patent CN220836748U discloses a color sorter for rice processing, which includes a color sorting cylinder. A plurality of optoelectronic sorting devices blowing towards the rice to be color sorted are installed in the color sorting cylinder. An inlet hopper is eccentrically arranged at the top of the color sorting cylinder. A vibration motor is fixedly arranged at the center of the top of the color sorting cylinder. A spiral guide plate is installed in the color sorting cylinder. The air blowing port of the optoelectronic sorting device is located below the discharge port of the spiral guide plate. A partition plate is fixedly arranged at the bottom of the color sorting cylinder. The partition plate divides the bottom wall of the color sorting cylinder into a finished product area and a waste area. Rice is added into the color sorting cylinder through the inlet hopper, and at the same time, the vibration motor is started, so that the rice slowly falls along the spiral guide plate. Since the spiral surface of the spiral guide plate is large, it can effectively prevent the rice from piling up. Since the pitch of the spiral guide plate is small, it can extend the falling path of the rice, further preventing the optoelectronic sorting device from missing selection due to the rice falling too fast;

[0003] However, the spiral structure is very complex and not easy to clean, and it is easy to be blocked. And if the falling speed of the rice cannot be controlled, the rice will still gather together. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the problems existing above, a rice color sorter is provided, which solves the above problems.

[0005] The utility model solves its technical problem by adopting the following technical solutions:

[0006] A rice color sorter includes a color sorting machine with a hopper. The hopper is fixed on the color sorting machine by bolts. And a strip-shaped necking is arranged at the lower end of the hopper for discharging rice. An intermittent discharging roller is rotatably arranged in the lower port of the hopper. The intermittent discharging roller is annularly and spacedly provided with rice grooves for discharging the rice from the hopper at intervals. And a dispersion vibration screening device is further arranged between the discharge port of the hopper and a conveyor belt arranged in the color sorting machine, for dispersing a row of rice discharged by the intermittent discharging roller and then falling on the conveyor belt, so that the rice on the conveyor belt is distinct and does not pile up, and thus can be more accurately identified when passing through an optoelectronic scanner.

[0007] Preferably, a dispersion vibrating screen is further provided in the color sorter. The dispersion vibrating screen is lifted by a hopper bolted to the inner wall of the color sorter. A spring is fixedly provided at the lower end of the hopper, and the lower end of the spring is connected to the dispersion vibrating screen. A side frame is fixedly provided on the side of the dispersion vibrating screen, and a vibration motor is bolted to the side frame. The dispersion vibrating screen vibrates up and down driven by the vibration motor, further dispersing the rice discharged by the intermittent discharge roller.

[0008] Preferably, sieve holes are provided at intervals in the dispersion vibrating screen.

[0009] Preferably, rubber separation strips are provided at intervals in the dispersion vibrating screen to separate several columns of the sieve holes.

[0010] Preferably, after the vibration motor drives the dispersion vibrating screen to vibrate, the undulating height of the rice is not greater than the height of the side guardrail of the dispersion vibrating screen.

[0011] Preferably, a number of rice grooves are provided at annular intervals on the intermittent discharge roller for discharging the rice. By controlling the motor driving the intermittent discharge roller, the rotation speed of the intermittent discharge roller can be changed, thereby changing the discharge frequency of the rice.

[0012] The advantages and positive effects of the present utility model are as follows: Workers add materials into the hopper, and then the motor drives the intermittent discharge roller to rotate, discharging the rice in batches through the rice grooves. After being discharged, it falls into the dispersion vibrating screen, and is further dispersed under the vibrating state, and falls onto the conveyor belt through the sieve holes, thereby evenly dispersing the centrally discharged rice, facilitating orderly passing through the photoelectric scanning part under the conveying of the conveyor belt for scanning and screening. Compared with the existing patents, the structure is simpler, the assembly is simple, the maintenance is convenient, and it is easy to clean, and the flow rate of the rice can be adjusted.
