Parallel vibrating screen used for separating maggots from culture medium mixture

Abstract

The invention discloses a parallel vibrating screen used for separating maggots from culture medium mixture, and particularly relates to the field of maggot breeding industry by using solid livestock excrement. The parallel vibrating screen comprises a static platform, a first branch chain, a second branch chain, a third branch chain and a screening frame. Kinematic pair ball pairs of the tail ends of the first branch chain, the second branch chain and the third branch chain are connected with the screening frame. Power sources of all the branch chains are started simultaneously, and the three branch chains are driven to achieve translational vibration along an X axis, translational vibration along a Y axis and translational vibration along a Z axis of the screening frame. According to the maggot separating vibrating screen based on a parallel mechanism, defects of an existing maggot separating processing technology can be overcome, quick controllable separating of the maggots and solid livestock excrement particles is achieved, the screening efficiency of the vibrating screen is improved, the space volume of whole equipment is small, the rigidity is high, the screening performance is stable and reliable, and the practical significance for factory application is achieved.

Description

technical field [0001] The invention mainly relates to the field of multi-dimensional vibrating screening equipment for agricultural biological materials, in particular to a parallel vibrating screen used for separating fly maggots and medium mixtures. Background technique [0002] Vibrating sieve is a device for grading and sorting material particles. It has been maturely used in chemical industry, metallurgy, coal, construction, petroleum, water conservancy, agricultural grain screening, seed sorting, organic fertilizer turning and throwing and other fields. The traditional vibrating screen has a single movement track, it is difficult for materials to be distributed quickly and evenly on the screen, it is easy to block the screen, the screen penetration rate is low, the overall equipment is too large, the cost is high, and it is easy to cause resonance and reduce the service life of the vibrating screen. [0003] The feeding of fly maggots with solid livestock and poultry ...

AI Technical Summary

Problems solved by technology

At present, the status quo of the livestock and poultry manure breeding fly maggot industry is mainly manual operation, with a low degree of mechanization and automation, mainly scattered small-scale individual farmers, and a low degree of industrialization. The most critical problem is the lack of fly maggots. The rapid and controllable separation technology of mature fly maggots and livestock and poultry manure medium in the breeding production chain is currently almost uncontrollable non-mechanical separation technology using the biological characteristics of fly maggots, and the efficiency is low
