because a plurality of discharge holes are formed, the discharge holes are distributed at equal intervals along the bandwidth direction of the rubbing conveyer belts 611 and are positioned right above the contact surfaces of the two groups of rubbing conveyer belts 611, sand grains after being heated can accurately fall between the two groups of rubbing conveyer belts 611, at the moment, the first driving shaft 200 drives the roller shafts 612 on the two groups of cleaning assemblies 610 to rotate in opposite directions through the first transmission assembly 510, so that the two groups of rubbing conveyer belts 611 and the bristles 613 arranged on the two groups of rubbing conveyer belts 611 rotate in opposite directions, one end of the roller shaft 612 is provided with the adjusting assembly 620, the rotation of the roller shaft 612 enables the A cylindrical cam 621A to rotate on the B cylindrical cam 621B, the limiting guide grooves formed on the A cylindrical cam 621A and the B cylindrical cam 621B are consistent, the A cylindrical cam 621A moves on the B cylindrical cam 621B, the A cylindrical cam 621A is driven to move through different positions of the limiting guide grooves and drives the roller shaft 612 to reciprocate, meanwhile, the retractable plate 622 is adapted to reciprocate of the roller shaft 612 for retraction, so that when sand falls between the two rubbing conveyor belts 611, the bristles 613 drive the sand to vertically descend, the reciprocating motion of the roller shaft 612 enables the two groups of rubbing conveyor belts 611 to move oppositely, the sand is driven to move along the axial direction of the roller shaft 612 in the descending process, the contact area between the sand and the rubbing conveyor belts 611 is increased, the sand can roll between the two groups of rubbing conveyor belts 611, the rubbing cleaning of the surface of the sand is realized, and pulp, peel and shells attached to the surface of the sand can be brushed away in the rolling process of the sand by the arrangement of the bristles 613;

Because the roll shaft 612 comprises an a roll 612A and a B roll 612B which are connected with each other in a rotating way, a differential transmission assembly 630 is installed inside the B roll 612B, the first driving shaft 200 drives the a roll 612A to rotate through a first transmission device when rotating, the a roll 612A drives the B roll 612B to rotate through the differential transmission assembly 630, the same-direction different-speed rotation between the a roll 612A and the B roll 612B is formed by a second transmission device, and the same-direction different-speed rotation between the a roll 612A and the B roll 612B corresponding to the two groups of cleaning assemblies 610, and the same-direction different-speed rotation between the a roll 612A and the B roll 612B when sand grains are positioned between the a roll 612A or the B roll 612B, the different-speed between the corresponding a roll 612A and the B roll 612B can enable the sand grains to move along the direction vertical to the roll shaft 612 in the descending process, and the sand grains can rotate omnidirectionally between the two groups of rubbing conveyer belts 611 by combining the axial movement of the sand grains along the roll 612, the cleaning effect is better;

when the roller shaft 612 rotates, the cam posts 642 are driven to rotate by the second transmission assembly 520, and a plurality of cam posts 642 are arranged inside each group of cleaning assemblies 610, the cam posts 642 on two groups of cleaning assemblies 610 are arranged in a staggered manner, the rotation direction of the cam posts 642 on each adjacent horizontal height is opposite, when the cam posts 642 rotate, the salient points of the cam posts 642 are combined with the kneading conveyer belt 611, the kneading conveyer belt 611 is deformed along with the continuous rotation of the cam posts 642, when the cam posts 642 on two groups of cleaning assemblies 610 simultaneously press the kneading conveyer belt 611, the kneading conveyer belt 611 is in a tensioned state and presses the kneading conveyer belt 611 to be wavy, at this time, the movement path of sand grains on the kneading conveyer belt 611 is increased by the deformation of the kneading conveyer belt 611, and the cleaning time between the two groups of kneading conveyer belts 611 is synchronously increased, the cleaning of sand grains is further improved, when deformation is generated by the rubbing conveying belt 611, the gap between two groups of corresponding bristles 613 at the deformation position is increased, the problem that the sand grains are clamped on the bristles 613 can be further avoided by utilizing the increase of the gap between the bristles 613, when the rotation directions of the cam post 642 and the roller shaft 612 are the same, the cam post 642 shifts the sand grains downwards through the deformation of the rubbing conveying belt 611, the downward movement of the sand grains can be accelerated, pulp, peel and shells attached to the surfaces of the crushed sand grains are squeezed through pressure generated by squeezing, when the rotation directions of the cam post 642 and the roller shaft 612 are opposite, the cam post 642 shifts the sand grains upwards through the deformation of the rubbing conveying belt 611, the sand grains are driven to further rotate between the two groups of rubbing conveying belts 611, and the cleaning of the sand grains is cleaner;

The back of the cleaning component 610 is provided with a bristle rod 614, one end of the bristle rod 614 is provided with a plurality of support rods, the support rods are inserted into the bristles 613 of the kneading and conveying belt 611, when the kneading and conveying belt 611 drives the bristles 613 to rotate, sundries attached to the bristles 613 are combed down by the plurality of support rods to clean the bristles 613, then the bristle rod 614 is detachably connected with the tank body 100, the bristle rod 614 extends into the tank body 100 through the mounting hole, and after the cleaning component is used, the bristle rod 614 is drawn out from the mounting hole;

when the cleaned sand falls from the cleaning component 610, firstly, the cleaned sand passes through the air duct 616, a plurality of air ports are arranged in the air duct 616, a suction force is generated in the air duct 616 through the fan, and the fallen and crushed pulp, peel and husk are sucked into the air duct 616, so that the pulp, peel and husk are prevented from being mixed into the sand again;

after the sand is cleaned, the sand falls on the inclined guide groove 619 at the bottom of the tank body 100, the sand is conveyed into the lifting box 710 through the inclined guide groove 619, then the screw is driven to rotate by the third driving shaft 720, the lifting box 710 is driven to ascend by the rotation of the screw, a discharge valve at the bottom of the lifting box 710 is enabled to correspond to an inlet at the side surface of the tank body 100, and then the discharge valve is opened to put the cleaned sand onto the stir-frying cage 310.
