An imitation shark scale fisheye sieve

Abstract

The invention discloses a fish-eye sieve imitating shark scales, in particular to a fish-eye sieve designed based on the bionic shape of shark scales, and belongs to the field of cleaning machinery in post-harvest processing machinery for agricultural products. The fisheye sieve of the present invention includes a sieve plate and a fisheye sieve sheet; several fisheye sieve sheets are regularly arranged on the sieve plate; fisheye sieve holes are also arranged under each fisheye sieve sheet on the sieve plate; The sieves are in the shape of shark scales, and each fisheye sieve is provided with N protrusions and (N-1) grooves, wherein N is an integer ≥ 2. The present invention can reduce the resistance by adopting the shark scale-like fisheye sieve, which is beneficial to the sliding of the material, plays a certain guiding role, improves the one-way pushing ability and the reliability of the one-way pushing of the fisheye sieve, and improves the The conveying efficiency and screening speed of the vibration screening process are improved, thereby improving the working efficiency of the fisheye screen. The fish-eye sieve imitating shark scales of the invention is suitable for cleaning machines in post-harvest processing machines of agricultural products.

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...
