Abstract
The invention relates to the technical field of chemical fertilizer screening machines, in particular to a caking-prevention device of the chemical fertilizer screening machine. The problem that in chemical fertilizer screening, chemical fertilizer particles are prone to adhering on a screen is solved. The two ends of a beam are fixed to a rack of the chemical fertilizer screening machine, and the beam is sleeved with multiple swinging rods. Each swing rod is connected with the beam in a rotating mode, and a rubber strip is installed at the free end of each swinging rod. An arc-shaped groove is formed in the bottom of each swinging rod. Multiple fixed rods extend outwards in the radial direction from the outer wall of the lower portion of the beam and penetrate through the corresponding arc-shaped grooves. A spring is arranged between each fixed rod and the corresponding swinging rod. When the screen rotates, the rubber strips are thrown out and whip the screen after falling back, so that the chemical fertilizer particles which adhere to the inner wall of the screen are knocked off, it is avoided that cakes are removed through manually beating the screen, and manpower is liberated. Moreover, the rubber strips will whip the screen once the screen rotates, and therefore the chemical fertilizer particles on the screen can be removed in real time.
