The invention discloses a fertilizer spraying device for rice seedling raising. The device comprises: a vehicle body, a water tank is arranged at the top of the vehicle body; the water tank is fixedly connected with the vehicle body; a pressurizing mechanism is arranged on the front side of the water tank; a connecting column is arranged at the top of the water tank; a cross rod is arranged at the top end of the connecting column; the cross rod is rotationally connected with the connecting column, wherein sprayers are arranged at the two ends of the cross rod, one side of each sprayer is connected with a water pipe, the other end of each water pipe communicates with the water tank, and a driving mechanism is arranged at the bottom of the cross rod; a pressure relief mechanism is arranged on one side of the top of the water tank, wherein the pressure relief mechanism comprises an air cylinder. By arranging the connecting rod, when wheels rotate, a piston in the air cylinder can be driven to move, the air cylinder injects air into the water tank, liquid fertilizer in the water tank is pressed into the spray heads to be sprayed out, and the fertilizer spraying can be automatically completed only by pushing the vehicle body during use, so that the labor intensity is greatly reduced.
Description
technical field [0001] The invention relates to the field of fertilizer spraying, in particular to a fertilizer spraying device for rice seedling raising. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The science that studies agriculture is agronomy. The labor objects of agriculture are living animals and plants, and the products obtained are the animals and plants themselves. , Agriculture provides basic products that support the construction and development of the national economy. When the soil cannot provide the nutrients needed for crop growth and development, the behavior of supplementing crops with artificial nutrients is called fertilization. [0003] At present, in the process of spraying liquid fertilizers for rice seedlings, most of them are sprayed manually by shoulder-back spraying equipment, w...
