Seed selection device and method for leafy vegetables in hot season shortage periods

Abstract

The invention discloses a seed selection device and method for leafy vegetables in hot season shortage periods and belongs to the technical field of leafy vegetable seed selection in hot season shortage periods. The device comprises a seed selection box, a driving mechanism is arranged on the inner side of the lower end of the seed selection box; the driving mechanism comprises a first driving motor, a cam, a pulley, a mounting base, a push rod, a telescopic spring and a positioning plate, one end of the push rod penetrates through the positioning plate and a collecting tank which are arrangedfrom bottom to top to be mounted on a filter screen, a drainage pipe is arranged at the lower end of the collecting tank, and one end of the drainage pipe is located above an oval screening barrel. According to the invention, the driving mechanism continuously shakes the filter screen; the seeds can pass through the filter screen and fall into the collecting tank; the seeds enter the oval screening barrel through a second feeding port, the oval screening barrel rotates to enable the seeds to continuously roll over, the unqualified small seeds fall into a collecting box through the screening holes, the qualified seeds are left in the oval screening barrel, manual intervention is not needed in the whole operation process, the labor intensity is low, and the seed selection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of seed selection of volt-deficient leafy vegetables, in particular to a seed selection device and method for volt-deficient leafy vegetables. Background technique [0002] Leafy vegetables refer to vegetables that use the fat and tender leaves and petioles of plants as edible parts. Common leafy vegetables include: celery, cabbage, cabbage, green cabbage, purple cabbage, etc. [0003] When planting leafy vegetables, it is necessary to select suitable seeds in order to grow abundant vegetables. Most of the seed selection of vacant leafy vegetables in the prior art is manual selection, which needs to consume a lot of manpower, and its labor intensity is high and the selection efficiency is high. Low, therefore, be badly in need of a kind of volt-deficit leaf vegetable seed selection device and method to solve the above problems. Contents of the invention [0004] The object of the present invention is to p...
