Agricultural seedling raising device

Abstract

The invention relates to an agricultural seedling raising device. The agricultural seedling raising device comprises an inner barrel and an outer barrel; a water tank is arranged between the inner barrel and the outer barrel, and the inner top of the water tank is provided with an exhaust pipe which is arranged inside the inner barrel; the top of the inner barrel is provided with a cover plate with air holes, the inside of the inner barrel is provided with an air inlet tank which is provided with an air inlet holes, the top of the air inlet tank is provided with a baffle, gaps are formed between both sides of the baffle and the inner wall of the inner barrel, and the baffle is provided with an air pipe; the air inlet tank is communicated with one end of an air duct arranged at the bottom of the inner barrel, the inside of the air duct is provided with a fan, the outside of the air duct is wound with electric heating wires which are wrapped by a thermal insulating layer, the other end of the air duct is communicated with a water injecting pipe through a check valve, one end of the water injecting pipe is communicated with the outside, the other end of the water injecting pipe is communicated with an input pipe, and the end portion of the input pipe is provided with a through hole, penetrates through the inner barrel and the water tank and is arranged at the inner bottom of the water tank. The agricultural seedling raising device can heat air in the environment where seedlings are arranged and meanwhile continuously supplement water to meet the growth requirements of the seedlings on suitable environment.

Description

technical field [0001] The invention belongs to the field of seedling raising equipment, in particular to an agricultural seedling raising device. Background technique [0002] When raising seedlings in the existing forestry, the seedlings are generally placed in the indoor cultivation soil directly. In this seedling raising method, the seedlings are directly exposed and are easily infested by diseases and insect pests, which affects the survival rate of the seedlings. In addition, the existing seedling raising devices generally directly heat the inside of the seedling raising box, which often has the problem of uneven heating, and lacks corresponding water circulation, resulting in dry air inside the seedling raising box, affecting the growth of seedlings. Contents of the invention [0003] The object of the present invention is to provide an agricultural seedling raising device. The present invention not only heats the air in the environment where the seedlings are locat...
