Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a screening oscillating screen. Background Art

[0002] Ethephon is a plant growth regulator that promotes plant maturation. After entering the plant body, it will release ethylene depending on the pH value of the plant tissue, which plays a role in promoting fruit maturation, inhibiting elongation growth, promoting organ abscission, inducing flower bud differentiation, promoting germination, inhibiting flowering, and promoting the occurrence of adventitious roots. The advantages of ethephon are used to produce ethephon granules on the market. Before its production, the raw materials of ethephon granules need to be screened using a screening vibrating screen to ensure the quality of ethephon granule production.

[0003] For example, a spiral screening oscillating screen with Chinese patent application number CN202321680721.2 can be used, including an outer frame and a screw, a screen is fixedly connected to the inner wall of the outer frame, and a collecting trough is provided at the bottom of the screen, a block is provided at one end of both sides of the outer frame, and one end of the block is located between two adjacent screw teeth of the screw, and a torsion spring is provided at the other end of the block, and a fixed plate is fixedly connected to one end of the outer frame near the block, and a spring is fixedly connected to the top of the fixed plate. The utility model realizes the vibration effect by frequently getting the screw and the block stuck and disengaged, so that the motor does not directly contact the vibrating component, greatly improving the service life of the motor, and the torsion spring and the spring have their own elasticity to reduce the collision intensity during the vibration of the screen, improve the service life, and reduce the noise generated.

[0004] However, in actual use, the above device only screens the raw material of ethephon granules once through the screen and cannot achieve multiple screenings. The screening effect is poor, which reduces the scope of application. At the same time, dust is easily generated during the screening process or dust adheres to the surface of the raw material of ethephon granules, affecting the quality of ethephon granule production.
