[0017] like Figure 1 As shown, a rice appearance quality testing device includes a frame 1, a rice huller 2 mounted on the top surface of the frame 1, a conveyor 3 mounted on the right side of the rice huller 2, a second feed hopper 3-1 of the conveyor 3 connected to the discharge port of the rice huller 2, a rice polishing machine 5 arranged on the right side of the conveyor 3, a first discharge hopper 3-2 of the conveyor 3 positioned above the third feed hopper 5-1 of the rice polishing machine 5, a conveyor belt 6 arranged on the right side of the rice polishing machine 5, and a vibrating screen 8 arranged on the right side of the conveyor belt 6.

[0018] The top surface of the rice huller 2 is connected to a first feed hopper 2-1. The rice huller 2 can be a rubber roller rice huller, the main components of which include rubber rollers: a pair of horizontally arranged rubber or plastic rollers, which are the core components of the rice huller, and the two rollers rotate in opposite directions at different speeds; a pressing device: used to adjust the pressure between the two rollers to ensure that the rice is smoothly dehulled during the squeezing and tearing process; a feed hopper: to feed the rice evenly between the two rollers; a discharge port: from which the separated brown rice and rice husks are discharged; and a blower: used to separate the rice husks from the brown rice. Working process: 1. Feeding: The rice is evenly fed into the space between the two rubber rollers through the first feed hopper 2-1; 2. Squeezing and tearing: The two rubber rollers rotate in opposite directions at different speeds, and the rice is squeezed and torn between the two rollers, separating the husks from the brown rice; 3. Separation: The separated brown rice and rice husks are discharged through the discharge port. The blower separates the rice husks from the brown rice, and the brown rice enters the second feed hopper 3-1, where the rice husks are collected.

[0019] The conveyor 3 is arranged obliquely, the conveyor 3 is arranged as a spiral conveyor, and the first weighing device 4 is arranged on the conveyor 3; by arranging the first weighing device 4, the conveyor 3 has a weighing function, and the dynamic metering of the material can be realized; the spiral conveyor with the weighing function is composed of a weighing bridge, a weighing sensor, a speed sensor, a weighing control instrument, a spiral conveying system, an electric control system and the like; in use, the material is conveyed to the weighing bridge for weight detection, and the speed sensor detects the speed of the spiral body at the same time; the weight signal and the speed signal are sent to the weighing controller for processing together, and finally the instantaneous flow and the cumulative amount are displayed.

[0020] The right side of the rice polishing machine 5 is connected with a second discharge hopper 5-2, and the second discharge hopper 5-2 is located above the conveying belt 6; the rice polishing machine is a device for unhulling rice and polishing brown rice; in use, the brown rice enters the machine from the feeding hopper 5-1, the motor drives the main shaft through the V-belt to rotate the grain feeding roller and the grain feeding cylinder, and the brown rice is pushed forward along the axis to enter the inside of the polishing chamber; under the comprehensive pressure of the grain feeding roller, the grain feeding cylinder, the polishing cylinder, the polishing roller, the bran removing net and the discharge port, the brown rice is extruded, and the brown rice is polished by mutual friction between the brown rice and the brown rice, between the brown rice and the polishing roller and between the brown rice and the bran removing net; when the rice grains reach the required accuracy, the rice grains are discharged from the second discharge hopper 5-2 to the conveying belt 6; at the same time, the fan under the polishing chamber draws air into the polishing chamber from the main shaft hole, so that the rice grains in the polishing chamber are fluidized, the polishing effect of the rice is strengthened, and part of the heat generated in the polishing process is taken away; the bran is discharged from the fan to the bran collector through the bran removing net and the bran suction hose and is collected and bagged.

[0021] The conveying belt 6 is provided with a second weighing device 7, and the second weighing device 7 can be an electronic belt scale; the electronic belt scale is a device for dynamic weighing, and can measure the weight of the material in real time during the material conveying process; the working principle is based on the combination of the weighing sensor and the speed sensor, and the flow and the cumulative weight of the material are calculated by accurately measuring the weight of the material and the speed of the conveying belt.
