Manual opening and closing fertilizer applicator and its usage method

Abstract

A manual opening and closing fertilizer applicator and an application method thereof are disclosed, the fertilizer applicator includes a rhombus-shaped opening and closing shoveling mouth, a feeding tube, a discharge valve, a measuring cup, a material control switch and a handle, the rhombus-shaped opening and closing shoveling mouth is installed at the lower end of the feeding tube, the rhombus-shaped opening and closing shoveling mouth includes a fixed shoveling mouth and a movable shoveling mouth, the fixed shoveling mouth is fixed on one side of the lower end of the feeding tube, the movable shoveling mouth is in hinged connection with the other side of the lower end of the feeding tube; the discharge valve is fixed on the movable shoveling mouth, the handle includes a first handle and a second handle, the first handle is fixed on the outer wall of the feeding tube, the second handle is fixed on the movable shoveling mouth, the measuring cup is mounted on the lower part of the cavity of the feeding tube, a discharge channel passes through the middle part of the measuring cup, the fertilizer application dosage can be controlled according to different cross-sectional sizes of the discharge channel of the measuring cup, an open window is arranged on the lower tube wall of the feeding tube; the open window is provided with a seal plate, and the material control switch is mounted in the cavity of the feeding tube, and in linkage with the second handle. The fertilizer applicator has reasonable design and simple structure, and can precisely control the fertilizer application dosage, and a fertilizer does not adhere on the rhombus-shaped opening and closing shoveling mouth, so that the fertilizer applicator can be used in wet soil and clay.

Description

technical field [0001] The invention relates to a fertilizer applicator, in particular to a manual opening and closing fertilizer applicator capable of precisely controlling the amount of fertilization and its use method. Background technique [0002] The concept of "precision fertilization" comes from precision agriculture. According to the soil properties of crop growth, analyze the law of crop fertilizer demand, adjust fertilizer input, make full use of soil productivity, and achieve higher income with the least fertilizer input, thereby improving the utilization rate of chemical fertilizers, improving the farmland environment, and increasing agricultural planting benefits. [0003] As we all know, the current seasonal utilization rate of chemical fertilizers in our country is low. Implementing precise fertilization and farming according to scientific methods will greatly save the amount of chemical fertilizers, reduce agricultural investment, and increase planting benefi...

Problems solved by technology

[0004] The disadvantage of the existing knapsack fertilizer applicators on the market is that the fertilizer is in contact with the perforated mandrel. When used in wet soil and clay, the fertilizer will stick to the mandrel, and the soil cannot be covered after fertilization, and the length of the handle cannot be adjusted. The pipe cannot be adjusted, too many accessories are not durable, and the operation requirements of the user are high
