A hydroponic device for barley seedlings

Abstract

A barley seedling water planting device comprises a casing, a water tank is arranged over the casing, the bottom side of the water tank is connected with the upper ends of support bars, the lower endsof the support bars are all fixedly connected to the bottom of the casing, the bottom of the water tank is fixedly connected with the upper end of a vertical tube, a through hole is formed in the topside of the casing, the through hole is collinear with the vertical center line of the casing, the vertical tube penetrates the through hole, the lower end of the vertical tube is fixedly mounted with a nozzle, the periphery of the vertical tube is connected to the inner circle of a first gear via a bearing, the bottom of the first gear is fixedly connected to the upper end of a torsion spring, the lower end of the torsion spring is fixedly connected with the top side of the casing, the vertical penetrates through the internal of the torsion spring, the upper portion of the vertical tube is fixedly provided with a roller type valve core, the bottom of a valve rod of the roller type valve core is fixedly connected to the upper end of a connecting rod, and the lower end of the connecting rod is fixedly connected to the top side of the first gear. Thus, a water planting liquid can be added quantitatively regularly, the labor intensity is reduced greatly, and the barley seedlings are avoided from slow growth caused by that the water planting liquid is forgotten to be added.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a barley seedling hydroponic device. Background technique [0002] Barley, also known as Mou wheat, rice wheat, and naked barley, has similar nutritional components to wheat, but has a slightly higher cellulose content. In recent years, with the emergence of its medicinal value, therapeutic value and economic value, barley has been paid more and more attention by people. In order to further study barley, the publication number CN104813831B records a rapid indoor cultivation method of wild barley, which solves the problems of slow germination, weak plants and slow growth of wild barley in the wild. , It is necessary to spray the hydroponic liquid regularly, and now people spray it manually, which is labor-intensive and low in work efficiency. Contents of the invention [0003] The invention provides a barley seedling hydroponic device to solve the defects in the ...
