Liquid fertilizer hole prickling and injecting mechanism

Abstract

The invention provides a liquid fertilizer hole prickling and injecting mechanism, and belongs to agricultural machinery. The liquid fertilizer hole prickling and injecting mechanism is characterizedin that transmission shafts are inserted into bearing blocks at the front side and back side of a mounting frame; a driving gear is fixedly arranged at one end of each transmission shaft, and a rockerarm is fixedly arranged at the other end of each transmission shaft; an upper plug is fixedly arranged at the upper end of a fertilizer applying needle casing; a second check valve is axially and movably arranged in a cavity of the fertilizer applying needle casing; a pin shaft is sequentially inserted into a notch slide passage at the side wall of the fertilizer applying needle casing and the second check valve; both ends of a connecting rod are respectively hinged to a pin shaft and the rocker arm; a first check valve is fixedly arranged at the left side of the upper part of the fertilizerapplying needle casing, and the upper end of the first check valve is fixedly arranged on a fertilizer conveying pipe, and is communicated with the fertilizer conveying pipe; one end of a swinging rodis fixedly arranged at the right side of the upper part of the fertilizer applying needle casing, and the other end of the swinging rod is hinged to the mounting frame. The liquid fertilizer hole prickling and injecting mechanism has the characteristics that the synchronous continuous operation of hole prickling and liquid fertilizer injecting is completed by the crank and rocker rod-driven typehole prickling and injecting mechanism; the structure is novel and compact, the operation quality is high, and the reliability in use is realized.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a hole-piercing and fertilizing operation component on a liquid fertilizing machine. Background technique [0002] For a long time, chemical fertilizer application is one of the important means to ensure the increase of crop production. However, due to the unreasonable application of chemical fertilizers in my country, the utilization rate of chemical fertilizers is low, resulting in serious environmental pollution. The characteristics of small environmental pollution and significant economic and social benefits have been popularized in agricultural production. A variety of liquid hole fertilizing machines have emerged as the times require. However, in order to realize the synchronization of hole piercing action and liquid fertilizer spraying, it is necessary to design a separate spray control system to cooperate with the hole piercing mechanism. There will be a certain response time...

[0002] For a long time, the application of chemical fertilizers has been one of the important means to ensure the increase of crop production. However, due to the unreasonable application of chemical fertilizers in my country, the utilization rate of chemical fertilizers is low and serious environmental pollution is caused. The characteristics of less environmental pollution, significant economic and social benefits, have been promoted in agricultural production

A variety of liquid hole fertilization machines have emerged as the times require. However, in order to realize the synchronization of the hole piercing action and the liquid fertilizer spraying, it is necessary to design a separate liquid spray control system to cooperate with the hole piercing mechanism. There will be a certain response time, which will affect the operation effect of the machine tools. and increase the weight and cost of the machine
