Shark scale-like fisheye screen

Abstract

The invention discloses a shark scale-like fisheye screen, in particular to a fisheye screen bionically designed based on a shape of a shark scale and belongs to the field of cleaning and separating machinery in agricultural product harvesting post-treatment machinery. The fisheye screen comprises a screen plate and fisheye screen pieces; the screen plate is regularly provided with a plurality offisheye screen pieces; a fisheye screen pore is also arranged below each fisheye screen piece on the screen plate; and each fisheye screen piece is in a shape of the shark scale and is provided with Nbulges and (N-1) grooves, wherein N is an integer larger than or equal to 2. For the shark scale-like fisheye screen provided by the invention, by adopting the shark scale-shaped fisheye screen pieces, the resistance can be reduced, sliding down of a material is facilitated, a certain guide effect is exerted, the unidirectional pushing ability and the unidirectional pushing reliability degree ofthe fisheye screen are improved, the conveying efficiency in the vibration screening process is improved, the screening speed in the vibration screening process is increased, and thus the working efficiency of the fisheye screen is improved. The shark scale-like fisheye screen provided by the invention is suitable for the cleaning and separating machinery in the agricultural product harvesting post-treatment machinery.

Description

technical field [0001] The invention relates to a fish-eye sieve imitating shark scales, in particular to a fish-eye sieve designed based on the bionic shape of shark scales, which belongs to the field of cleaning machinery in post-harvest processing machinery of agricultural products. Background technique [0002] Cleaning is an indispensable part of grain harvesting. Grain cleaning machinery is mainly used to remove mechanical damage, broken and immature grains, grass seeds, sediment, ear shells and other impurities. They separate. [0003] Sieve is an important grain cleaning machine, including woven sieve, fisheye sieve, punching sieve, fish scale sieve and other forms. The sieve with non-adjustable inclination is usually called fisheye sieve, and the sieve with adjustable inclination is called fish scale sieve. The fish-eye screen is a raised fish-eye-shaped crescent-shaped screen hole punched on a thin steel plate. This screen hole can reduce the chance of short ste...

Problems solved by technology

[0005] In order to solve the problem of low one-way material pushing efficiency of existing fisheye sieves, the present invention provides a fisheye sieve imitating shark scales with good guiding effect and high pushing efficiency. The protrusion and groove structure can improve the screening speed and work efficiency. The technical scheme adopted is:
