Problems solved by technology

Patent 2011100038822.X discloses a hydraulically driven proportional pump. The reversing of the piston is controlled by a spring. Since the spring is frequently stretched and compressed, it is easy to cause damage to the spring, making the piston unable to perform reversing work.

Abstract

The invention relates to a hydraulically-driven proportion-fixed fertilizer applying pump. The pump comprises a shell, a piston, a piston rod, a sliding seal, a one-way piston valve, a sealing fin, a spring and a one-way valve; two control grooves are formed in the piston rod, and the control groove close to the piston is used for controlling communication and closing between a cavity below the piston and an upper cavity and a lower cavity of the sliding seal, the control groove far away from the piston is used for controlling communication and closing between the lower cavity of the sliding seal and a liquid mixing chamber, thereby the position of the sliding seal is controlled through the control grooves of the piston rod, thereby different liquid channels are communicated, and reciprocating motion of the piston is achieved. A piston reversing mechanism of the pump is not under the influence of the spring, impact in the piston reversing process is decreased, and device operation efficiency and steadiness are improved.

Description

technical field [0001] The invention relates to a water and fertilizer integrated proportional fertilization device in the field of agriculture, in particular to a hydraulically driven fixed-ratio fertilization pump. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer is to use the pressure irrigation system to evenly and accurately transport the fertilizer liquid mixed with soluble solid fertilizer or liquid fertilizer to the root soil of crops together with irrigation water. Using irrigation and fertilization technology, the whole growth period demand design can be carried out according to the growth needs of crops, and water and nutrients can be directly provided to crops in a quantitative, regular and proportionate manner. [0003] The integrated water and fertilizer system mainly includes three parts: irrigation and fertilization ...
