[0015] The beneficial effects of the present invention are:

[0016] The rice seed impurity removal device is provided with a collecting mechanism, a collecting box, a cleaning box, a water inlet pipe, a first connecting rod, a second connecting rod, a flip plate, a first rotating rod, a second rotating rod, a water-dipping plate, a rotating disk, and a third rotating rod. The rice is put from a feeding hopper into a cleaning box, and the rice falls into the collecting mechanism. Water is introduced from the water inlet pipe, and the water flow impacts the flip plate to rotate the first rotating rod. The first rotating rod drives the third rotating rod to rotate through the first bevel gear and the second bevel gear, and then drives the second rotating rod to rotate through the third bevel gear and the fourth bevel gear. The rotating rod rotates, thereby rotating the rotating disk, and the rotating disk drives the second connecting rod to move, continuously pushing and pulling the first connecting rod, causing the water-discharging plate to rotate back and forth, thereby continuously changing the direction of the water flow. The chaotic water flow disperses the rice in the collecting mechanism, thereby washing out the dust on the surface of the rice and impurities such as chaff mixed in the rice. Lighter impurities such as chaff and dust float on the water surface, and then the staff salvages the debris and puts it into the collection box. The operation is simple, the rice is rinsed more cleanly, and it is conducive to quickly removing lighter impurities such as chaff and empty shells.

[0017] The rice seed impurity removal device has a magnetic block disposed at the bottom of a collecting net. After the rice enters the collecting net, under the impact of the water flow, metals such as broken iron filings in the rice sink downward and are adsorbed by the magnetic block, thereby facilitating the removal of metal impurities in the rice.

[0018] The rice seed impurity removing device is provided with a drying box, a fan, an air guide plate, a mounting block, a spring, a cam and a motor. The rice washed with water is put into the drying box, and the fan and the motor are started. The fan blows air into the drying box, which is heated by an electric heating wire and blown toward the air guide plate at the bottom of the drying box. The hot air is guided by the air guide plate and blown toward the bottom of a collecting mechanism. The gradually enlarged air guide plate makes the hot air received by the bottom of the collecting mechanism more uniform, so that the rice at the end far from the fan cannot be dried by the hot air and is difficult to dry. The output shaft of the motor drives the cam to rotate, and the cam hits the bottom of the collecting mechanism, so that the collecting mechanism vibrates continuously. The collecting mechanism hits the spring, so that the rice in the collecting mechanism shakes up and down, and the rice is shaken out, which is beneficial to the drying of the rice.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The overall structure of the invention is simple and compact, the rice impurity removal effect is good, and the cleaning is cleaner. BRIEF DESCRIPTION OF THE DRAWINGS
