Fertilizing device for agricultural planting

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an agricultural planting fertilizing device which comprises a bottom frame, a drilling machine mounted at the upper end of the bottom frame and capable of sliding in the height direction of the bottom frame in a guiding mode, and water storage tanks mounted on the two sides of the bottom frame. The water storage tanks are used for storing liquid fertilizer, and the piston rods are arranged at the ends, facing the drill bits, of the water storage tanks and move up and down in the height direction of the water storage tanks. A scraping block at the lower end of the ground drilling machine is intermittently contacted with an abutting block when the ground drilling machine starts to drill holes, the ground drilling machine continuously moves downwards, a piston rod continuously moves downwards by utilizing friction force between the scraping block and the abutting block, and when the piston rod moves downwards, a piston plate connected with the piston rod can press the liquid level in a water storage tank downwards, so that the liquid level in the water storage tank is pressed downwards; and the water is sprayed on the two sides of the drill bit through the water spraying pipe, so that the ground soil is gradually fertilized while the ground is wetted.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilizing device for agricultural planting. Background technique [0002] When the soil cannot provide the nutrients needed for crop growth and development, the act of supplementing the crops with artificial nutrients is called fertilization. Increasing soil nutrients can increase soil nutrients regardless of the application of organic fertilizers or inorganic fertilizers. Most inorganic fertilizers are easy to dissolve. , After application, crops can absorb it immediately, except partly reserved for soil absorption. [0003] The soil physical environment first affects the water and air supply of crops, and also directly affects the supply and storage of nutrients. In general fertile soil, its solid phase accounts for more than half of the entire soil volume, and the other half is full of water and air. Soil pores are not only responsible for the supply of cro...
