Manufacturing method for handheld topdressing rod with unlikely-to-block liquid outlet pipe

Abstract

The invention provides a manufacturing method for a handheld topdressing rod with an unlikely-to-block liquid outlet pipe. The manufacturing method comprises the steps of A. integrally preparing a columnar handle with plastic, and integrally casting protection handles at two ends of the handle; B. manufacturing a fertilizer liquid pipe with a steel pipe, turning a thread at one end of the fertilizer liquid pipe, performing threaded connection on the end of the fertilizer liquid pipe and the handle, and arranging a triangular pick head at the other end of the fertilizer liquid pipe, wherein during preparation, integral injection molding is realized on the pick head and an L-shaped through hole, the pick head is fixedly connected with the fertilizer liquid pipe, and the end part of the jumper head is sharp; C. connecting the other end of the handle with an external pipe in an insertion manner, wherein the external pipe is a rubber pipe or a plastic pipe; and D. forming a hole in the front end of the joint of the fertilizer liquid pipe and the handle, mounting a hydraulic valve in the hole, arranging a pressing shank at the upper part of the hydraulic valve, inserting the lower part of the hydraulic valve into the fertilizer liquid pipe, sleeving the outer wall of the hydraulic valve by a spring, pressing one end of the spring against the outer wall of the fertilizer liquid pipe, and pressing the other end of the spring against the pressing shank. The method disclosed by the invention is simple; a manufactured product is simple in structure and convenient to use; due to a manufactured liquid fertilizer application device, the labor intensity is alleviated, and the fertilizer utilization rate is high.

Description

[0001] technical field : [0002] The invention relates to the technical field of fertilization tools, in particular to a method for manufacturing a hand-held topdressing rod that is not easy to block a liquid outlet pipe. [0003] Background technique : [0004] The traditional fertilization of fruit trees and forestry adopts the method of digging trenches or planing pits, and placing the fertilizer inside the soil layer for fertilization operations. The fertilizer is absorbed by the crops slowly, and it is easy to lose in rainy weather, reducing the fertilizer efficiency. Moreover, the soil layer needs to be covered after planing the pit for fertilization, which is cumbersome and labor-intensive. In order to ensure the full use of fertilizer efficiency, most of the fertilizers have been changed to use liquid fertilizers, and fertilization is done by inserting deep into the soil layer. However, the current fertilization methods or equipment are not easy to operate. In ...
