A quantitative fertilization device for cotton planting

Abstract

A quantitative fertilization device for cotton planting, comprising an annular base, a support plate is arranged above the annular base, the left and right sides of the top side of the annular base are connected to the lower end of a screw rod through bearing rotation, and the upper end of the screw rod is connected to the support plate through bearing rotation The bottom side of the support plate and the top side of the support plate are provided with a first driving device for driving the screw to rotate, and a round tube is arranged in the annular base, and the screw nut is installed on the outer circumference of the screw rod. There are several discharge openings connected with the bottom of the annular groove on the bottom side of the bottom, and the lower end of the discharge opening is provided with a counterbore, and a baffle is hingedly installed in the counterbore through a torsion spring. The invention has simple structure and ingenious concept, can add fertilizers of different depths and different types of fertilizers in one fertilization pit, is convenient to use and operate, is convenient to control the amount of fertilizer added, and can be used as a soil sampler at the same time to sample the planting soil. Increased functional diversity can meet market demand and is suitable for promotion.

Description

technical field [0001] The invention belongs to the field of fertilization devices, in particular to a quantitative fertilization device for cotton planting. Background technique [0002] Cotton is one of the main crops produced by human beings. It can be made into fabrics of various specifications, suitable for making all kinds of clothes, furniture cloth and industrial cloth. In the production process of cotton, in order to improve the quality and output of cotton growth, often Fertilization devices are used to supplement the nutrients needed for cotton growth. Fertilization devices are more commonly used in agricultural production; however, different fertilizers have different fertilization depths, or the same fertilizer has different fertilization depths, resulting in different effects, so fertilizers need to be layered Fertilization can greatly improve the utilization rate of fertilizers, but the existing fertilization devices have a single structure and can only apply ...

[0002] Cotton is one of the main crops produced by human beings. It can be made into fabrics of various specifications, suitable for making all kinds of clothes, furniture cloth and industrial cloth. In the production process of cotton, in order to improve the quality and output of cotton growth, often Fertilization devices are used to supplement the nutrients needed for cotton growth. Fertilization devices are more commonly used in agricultural production; however, different fertilizers have different fertilization depths, or the same fertilizer has different fertilization depths, resulting in different effects, so fertilizers need to be layered Fertilization can greatly improve the utilization rate of fertilizers, but the existing fertilization device has a single structure and can only apply fertilizer at a fixed depth, which cannot meet actual needs. Therefore, we have invented a quantitative fertilization device for cotton planting
