Quantitative fertilization device for cotton planting

Abstract

The invention discloses a quantitative fertilization device for cotton planting. The quantitative fertilization device comprises an annular base, wherein a supporting plate is arranged above the annular base, the left side and the right side of the top side of the annular base are rotationally connected with the lower ends of lead screws through bearings, the upper ends of the lead screws are rotationally connected with the bottom side of the supporting plate through bearings, a first driving device for driving the lead screws to rotate is arranged on the top side of the supporting plate, round pipes are arranged in the annular base, nuts are installed on the periphery of the lead screws in a threaded mode, a balance weight plate is fixedly installed at the lower end of a telescopic rod, a plurality of discharging openings communicate with the bottom of the annular groove are formed in the bottom side of the round pipes, counter bores are formed in the lower ends of the discharging openings, and baffles are hinged into the counter bores through torsional springs. The quantitative fertilization device is simple in structure, ingenious in conception, capable of adding fertilizers with different depths and different types of fertilizers into one fertilization pit, convenient to use and operate, capable of conveniently controlling the amount of the added fertilizers, capable of serving as a soil sampler, capable of sampling planting soil, capable of increasing functional diversity, capable of meeting market requirements and suitable for popularization.

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
