Automatic nutrient solution replenishing device for multi-layer seedling raising rack

Abstract

The invention discloses an automatic nutrient solution replenishing device for a multi-layer seedling raising rack. The automatic nutrient solution replenishing device comprises a support, a solution receiving box and a solution storage box, wherein the top of the support is fixedly connected with the bottom of the solution receiving box. The invention relates to the technical field of seedling raising racks. According to the automatic nutrient solution replenishing device for the multi-layer seedling raising rack, when a nutrient solution in a nutrient solution tray is absorbed and reduced, through the cooperation of a movable plate and a counterweight, the counterweight is pressed down to pull a pulling string, a piston block is separated from the bottom of the solution storage box, the nutrient solution enters the nutrient solution tray, it is not required that workers add the nutrient solution every day, great manpower is liberated, and time is saved. When the nutrient solution in the nutrient solution tray is reduced, a floating plate can be lowered along with the reduction of the nutrient solution, a clamping block is separated from a solution conveying pipe, so that the nutrient solution in the solution conveying pipe enters the nutrient solution tray, and seedling culture is improved; it is only required that the solution storage box is filled with the nutrient solution every day, the workers do not worry about the situation that seedling loss is caused by negligence, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of seedling raising racks, in particular to an automatic nutrient solution supply device for multi-layer seedling raising racks. Background technique [0002] Because the seedlings of the plants are relatively fragile, it is difficult for the seedlings to survive in the natural environment. Therefore, it is generally necessary to cultivate the seedlings in a greenhouse environment to make them capable of adapting to the natural environment and then transplant them to the outdoor environment for planting. The cultivation of seedlings is of great significance for agricultural planting. The existing seedling trays generally have an integrated structure. The seedling tray has a body and a number of seedling holes formed on the body. The seedling holes are filled with culture medium, and the seeds of plants are sown in the seedling holes. After the seeds break through the soil, the seedling holes Create a growt...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic nutrient solution supply device for multi-layer seedling racks, which solves the problem that in the process of raising seedlings in multi-layer seedling racks, the supply of nutrient solution is mainly done manually, which is particularly time-consuming, laborious and wasteful. A large amount of labor, sometimes due to negligence, affects the problem of seedling cultivation
