[0016] See also Figure 1-2As shown, a seed grinding device comprises a grinding mounting frame 1, two bearing seats 2 are respectively installed on two lateral sections at the top of the grinding mounting frame 1 by bolts, a roller shaft 3 is rotatably connected between the two symmetrical bearing seats 2 by bearings, two roller shafts 3 are connected with first pulleys 4 at both ends of the bearing seats 2 at the outside, one of the roller shafts 3 is provided with a second pulley 5 at one end, a motor 6 is installed at the bottom of the grinding mounting frame 1, a third pulley 7 is connected to the rotating end of the motor 6, a grinding tank 8 is provided on the two roller shafts 3, the two second pulleys 5 at both ends of the two roller shafts 3 are transmission-connected by a first belt 9, the second pulley 5 and the third pulley 7 are transmission-connected by a second belt 10, the connection mode of the bearing seat 2 and the roller shaft 3 adopts a bearing rotation connection, so that the roller shaft can rotate smoothly, thereby improving the grinding effect, and the transmission connection of multiple pulleys and belts makes the operation of the whole system more stable, and the seeds can be quickly and effectively ground by motor drive and rolling grinding mode, thereby improving the production efficiency;

[0017] The outer surface of the roller shaft 3 is connected with a plurality of rubber rings 11 for increasing friction, which increases the friction between the roller shaft 3 and the tank body 81 and helps to grind the seeds better;

[0018] The grinding tank 8 includes a tank body 81, the outer surface of the tank body 81 is tightly attached to the two rollers 3, a tank cover 82 is threadedly connected to the tank mouth of the tank body 81, and a plurality of steel balls 83 are arranged in the tank body 81 to ensure uniform mixing and grinding of the seeds and the steel balls 83 in the tank body 81;

[0019] The diameters of the several steel balls 83 are different, and the degree of grinding can be adjusted to meet the grinding requirements of different types of seeds;

[0020] The tank body 81 and the tank cover 82 are made of iron or steel, which has high strength and wear resistance and can withstand large impact and grinding.

[0021] Working principle: first, place the seeds into the body 81 of the grinding jar 8, screw on the jar cover 82, and then place the grinding jar 8 on the two rollers 3, start the motor 6 to drive the third pulley 7 to rotate, the third pulley 7 transmits power to the second pulley 5 through the second belt 10 to rotate, the second pulley 5 rotates to drive one of the rollers 3 to rotate, the first pulley 4 at both ends of one of the rollers 3 transmits power to the first pulley 4 at both ends of the other roller 3 through the first belt 9, and at this time, the two rollers 3 rotate at the same time, so that the grinding jar 8 on the roller 3 rotates When the grinding jar 8 rotates, under the action of centrifugal force and friction, the seeds and steel balls 83 will rotate with the grinding jar 8. When their own power is greater than the centrifugal force, they will reach a certain height. Due to the gravity of the steel balls 83 themselves, they will break away from the inner wall of the jar body 81 and roll down. The steel balls 83 will crush the seeds in the jar body 81 with a huge impact force. As the grinding jar 8 runs, the sliding between the steel balls 83 will continue to grind the materials until they meet the standards. After the grinding is completed, unscrew the jar cover 82 and pour out the ground seeds.
