A self-adjusting bionic fan with variable angle

Abstract

The invention relates to the field of agricultural machinery, in particular to a self-regulating bionic fan with a variable angle, which consists of a center mounting carrier, a steering gear, bionic fan blades, a gas flow sensor and an embedded development board; the bionic Between the two points A and B on the upper half of the fan blade is the outer edge curve of the fan blade. The outer edge curve is formed by connecting a plurality of convex outer edge convex hulls (simulating the outer edge curve of the humpback whale fin) ; The inner edge curve of the fan blade is between the two points of the lower half of the bionic fan blade A', B', and the inner edge curve is formed by a plurality of (simulated humpback whale fin outer edge curves) concave inner curves. The bionic fan of the invention can imitate the swing of the fins of the whale when it is swimming, increase the air flow of the fan, and stabilize the air flow at the same time. It is suitable for the operation of the pneumatic seed meter in any environment .

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a self-regulating bionic fan with variable angle. Background technique [0002] With the increasing demand for sowing quality and speed in agricultural planting, the design and manufacture of seed metering devices have been paid attention to by people, and pneumatic seed metering devices are widely used due to their strong universality, small damage to seeds, high operating speed, and high operating accuracy. The advantages are more and more recognized by people. [0003] The fan of the fan is one of the most important devices of the pneumatic seed metering device. Its function is to provide stable wind pressure for the pneumatic seed metering device in order to improve the quality of sowing. When the seeder is working, the environment is complex and the operation is difficult. Affected by environmental factors, the airflow generated by the fan of the existing pneumatic see...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of insufficient airflow and difficulty in maintaining stable air pressure in the existing pneumatic seed metering fan, the present invention provides a self-adjusting bionic fan with variable angle, which can imitate the movement of the fins of a whale when it is swimming. Oscillating to increase the airflow of the fan while stabilizing the airflow, it is suitable for the operation of the pneumatic seed meter in any environment
