Vibration and airflow combined screening straightening-out mechanism

Abstract

The invention relates to a vibration and airflow combined screening straightening-out mechanism, comprising a frame, wherein two upper-layer screen body guide rails and two lower -layer screen body guide rails are arranged on the frame; upper-layer screen bodies are arranged on the two upper-layer screen body guide rails, while lower-layer screen bodies are arranged on two lower-layer screen body guide rails; each of the upper-layer screen bodies and the lower-layer screen bodies comprises a hydraulic cylinder; the tail end of the push rod of the hydraulic cylinder is fixedly connected to a screen frame; the bottom of the screen frame is fixedly connected to guide rail sliders on the two corresponding screen body guide rails; a plurality of screen pipes are arranged at intervals in each screen frame; the spacing between two adjacent screen pipes in the screen frame of the upper-layer screen bodies is greater than the spacing between two adjacent screen pipes in the screen frame of the lower-layer screen boxes; one end of each screen pipe is opened, while the other end thereof is closed; a plurality of air vents are formed at intervals in the wall of the pipe; a slot hole and a plurality of branch short holes are formed at one side edge of the screen frame, while a plurality of through holes are corresponding formed at intervals in the other side edge thereof; the opened ends of the screen pipes are connected to the branch short holes, while the closed ends of the screen pipes are correspondingly arranged in one through hole respectively; and the input end of the slot hole is connected to an intake pipe.

Description

technical field [0001] The present invention relates to a sorting out mechanism, in particular to a vibrating and air-flow combined screening that disperses clusters of strip-like tissue culture seedlings and arranges them regularly and evenly during the subculture process of plant tissue culture. Straighten out institutions. Background technique [0002] Plant tissue culture has become a rapid propagation and seedling method for many plants such as potatoes, sugarcane, red cotinus, Phalaenopsis, etc. However, due to the division and transplantation of plant tissue culture seedlings in the subculture process, a large amount of manpower and strict environmental pollution are required. Therefore, in Japan, Taiwan and other places, mechanized methods are used to divide and transplant the tissue cultured seedlings in the subculture process. At present, most of the existing research adopts the method of identifying, cutting and transplanting a single seedling. Generally, a speci...
