Quantitative fertilization device for agricultural production

Abstract

The invention is applicable to the technical field of agricultural production equipment, and provides a quantitative fertilization device for agricultural production. The device comprises a base, a supporting roller and a fertilization shaft, wherein the supporting roller is mounted on one side of the bottom of the base through a bracket; the fertilization shaft is mounted on the other side of thebottom of the base through a bracket; a material conveying part is rotatably mounted in the middle of the fertilization shaft, and a plurality of rows of punching pieces are arranged on the outer side of the fertilization shaft in a circumferential array manner; abutting pieces are arranged at the bottoms of the punching pieces in a protruding mode, sealing blocks and telescopic rods are sequentially installed at the upper ends of the abutting pieces, and the telescopic rods are elastically arranged in the punching pieces; the sealing blocks are arranged at outlets in the bottoms of the punching pieces, the internal spaces of the punching pieces are gradually changed, the spaces are gradually reduced from the fertilization shaft to the end spaces far away from the fertilization shaft, andfeeding ports of the punching pieces are communicated with a discharging port in the bottom of the material conveying part; and the two ends of the material conveying part are fixedly installed on the support.

Description

technical field [0001] The invention relates to the technical field of agricultural production equipment, in particular to a quantitative fertilization device for agricultural production. 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, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is the basic industry that provides support for the construction and development of the national economy. [0003] The soil needs to be fertilized in the process of agricultural planting, and the existing fertilization methods usually directly sprinkle the fertilizer on the soil surface. If it rains, the fertilizer on the surface will be lost with the rain, and the effect of fertil...

[0003] The soil needs to be fertilized in the process of agricultural planting, and the existing fertilization methods usually directly sprinkle the fertilizer on the soil surface. If it rains, the fertilizer on the surface will be lost with the rain, and the effect of fertilization will not be achieved. Therefore, it is proposed A quantitative fertilization device for agricultural production to solve this technical problem
