Fertilizer screening device capable of achieving automatic cleaning

Abstract

The invention discloses a fertilizer screening device capable of achieving automatic cleaning. The device comprises a machine frame, a motor, a cover and cylindrical screen cloth, wherein the cover is fixed to the machine frame, the cylindrical screen cloth is obliquely arranged in the cover, and a feeding hopper is arranged on the cover and located at the high end of the cylindrical screen cloth; a coarse material port is formed in the side, close to the low end of the cylindrical screen cloth, of the cover, and the cylindrical screen cloth is driven by the motor. The device is also provided with a cleaning mechanism, wherein the cleaning mechanism comprises a plurality of eccentric cams and a rotary shaft, the rotary shaft is connected to the cover in a rotary mode, the eccentric cams are connected to the axial direction of the rotary shaft, the rotary shaft is connected with the output end of the motor through a belt or a chain, and the eccentric cams can collide with the cylindrical screen cloth intermittently. When the device is used for screening, fertilizer adhering to the screen cloth can fall off under the vibration of the eccentric cams, and the screen cloth can not be blocked.

Description

technical field [0001] The invention belongs to the field of separating solids from solids by using fine sieves, coarse sieves, sieving or air flow, and in particular relates to a fertilizer screening device capable of automatic cleaning. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. [0003] In the process of fertilizer processing and production, particles of different sizes need to be screened, and unqualified fertilizer particles are screened out, discharged from the discharge port into the mixer for re-stirring and granulation. However, during the screening process, the fertilizer is easy to cause the screen to be blocked. At the same time, if the number of sieves is too high, some fertilizer will stick to the screen, which is also a reason for the screen to be blocked. At this time, manpower is needed to beat the screen. Make screen mesh h...

Problems solved by technology

However, during the screening process, the fertilizer is easy to cause the screen to be blocked. At the same time, if the number of sieves is too high, some fertilizer will stick to the screen, which is also a reason for the screen to be blocked. At this time, manpower is needed to beat the screen. Make the screen holes unobstructed, which consumes a lot of time and energy of the workers, and the production efficiency cannot be improved.
