[0011] Embodiment 1: A stone removal device for rice processing, such as Figure 1-Figure 3 As shown, it includes a base frame, a box body, a feed hopper, a sliding frame, a screen plate, a slide plate, an electric slide plate, a brush plate, an electric push rod, a fixed rod, a fan, an air outlet plate, an air outlet duct, an inclined plate, a fixed plate and a dust cover. A box body is welded on the upper part of the base frame, and the interior of the box body is a hollow structure. The upper part of the box body is connected to the feed hopper by rivets, and the feed hopper is connected to the interior of the box body. Four sliding frames are welded inside the box body, and two sliding frames located on the same horizontal plane are a group, and the two sliding frames in each group are symmetrically arranged. Screen plates are placed on the two groups of sliding frames, and a number of large circular holes are opened on the upper screen plate, and a number of small circular holes are opened on the lower screen plate. Both screen plates pass through one side of the box body, and two slide plates are connected to two slide plates by bolts on the upper part of the two screen plates. The two slide plates located on the same screen plate are a group, and the two slide plates in each group are symmetrically arranged. The slide plate is in contact with the sliding frame, and one side of the four slide plates is slidably connected to the electric slide plate, and a brush plate is welded between the two electric slides in each group, and a number of bristles are provided on the lower part of the two brush plates. , several bristles of the brush plate are in contact with the sieve plate, an electric push rod is connected to the upper part of the base frame by rivets, the telescopic rod of the electric push rod is fixedly connected to the sieve plate below, two fixing rods are welded between the two sieve plates, the two fixing rods are symmetrically arranged, and the two fixing rods are slidingly connected to the box body, a fan is arranged on the upper part of the box body, two air outlet plates are arranged on one side of the interior of the box body, the interiors of the two air outlet plates are hollow structures, the two air outlet plates are connected to the air outlet of the fan, several air outlet pipes are connected to the upper parts of the two air outlet plates by flanges, several air outlet pipes located on the same air outlet plate are a group, and the density of the lower group of air outlet pipes is greater than that of the upper group of air outlet pipes, an inclined plate is welded at the lower part of the box body, a discharge port is opened at the lower part of the box body, the inclined plate is in contact with the discharge port at the lower part of the box body, a fixed plate is arranged on the side of the two sieve plates away from the fan, the two fixed plates are inclined, a dust cover is welded on the side of the box body away from the fan, an opening is opened at the lower end of the dust cover, and the two fixed plates are located inside the dust cover.
[0012] At first, the telescopic rod of the electric push rod extends, and the sieve plate contacts the upper part of each set of sliding frames. First, the rice grains that need to be de-stoned are manually poured into the feed hopper, which is connected to the inside of the box body, so that the rice grains fall into the sieve plate above. Then the electric push rod and the fan are manually started, and the telescopic rod of the electric push rod will continue to shrink or extend, and the telescopic rod of the electric push rod will drive the two sieve plates and the two fixed rods to move up and down continuously.
