the amount of dry particles falling on the upper surface of the green brick is adjusted by adjusting the speed of a glaze line belt; or the rotating speed of a motor of the blanking roller is adjusted to adjust the amount of dry particles falling onto the upper surface of the green brick.

7. The method for continuously distributing dry particles on ceramic tiles as claimed in claim 1, wherein an adhesive baffle is connected to the lower opening of the storage hopper, one end of the adhesive baffle abuts against the outer side surface of the blanking roller and tightly clamps the blanking roller, the lower opening of the storage hopper is closed by matching a plurality of the adhesive baffles with the blanking roller after being spliced, and the clamping degree of the adhesive baffles relative to the blanking roller is adjusted by adjusting an opening adjuster of the storage hopper.

8. The continuous dry particle distribution method for ceramic tiles as claimed in claim 1, wherein the material suction fan is arranged at the upper end of the dry particle collecting barrel and driven by a material suction motor, the material suction fan is a negative pressure fan and is communicated with the dry particle collecting barrel, an air outlet of the material suction fan is a material suction outlet, and part of light and fine dry particles are sucked to the material suction outlet by the material suction fan and then discharged to the waste dust treatment tank.

9. The continuous tile drying and grain distributing method according to claim 1, wherein the grain drying machine is further connected with a dust removing device, the dust removing device comprises a dust suction motor, a dust suction fan and a dust suction pipe, the dust suction pipe comprises a dust inlet end and a dust outlet end, the dust inlet end is connected with a dust suction port arranged on the side wall of the grain drying machine shell, and the dust outlet end is connected with the dust suction fan.

10. A method for continuously distributing dry particles on ceramic tiles as claimed in claim 9, wherein dust exhaust ports are formed on two opposite front and rear side walls of the housing of the dry particle machine, the dust exhaust pipes comprise a main dust exhaust pipe and sub dust exhaust pipes, the number of the sub dust exhaust pipes is equal to that of the dust exhaust ports, one end of each sub dust exhaust pipe is connected with the dust exhaust port, and the other end of each sub dust exhaust pipe is connected with the main dust exhaust pipe.
