Rotor type liquid fertilizer applying channel shifting device

Abstract

The invention discloses a rotor type liquid fertilizer applying channel shifting device, which belongs to agricultural machinery. A main shaft sleeve, a left support and a right support are coaxially, sequentially and fixedly assembled on a locating plate; an inner tooth ring sprocket is welded and inserted in the holes of the right support and the left support; a main shaft of the sprocket is inserted in the holes of the left support and the main shaft sleeve; two gear shafts are respectively assembled in two fertilizer delivery holes of the main shaft of the sprocket; a right push rod support and a push rod locating plate are assembled on the end part of one side of the main shaft of the sprocket; a left push rod support is fixedly assembled on the left end face of the right push rod support; two push rods are inserted into the left push rod support and the right push rod support; a second pressure spring is in fit installed between the left push rod support and a push rod shaft shoulder; an end cover is fixedly assembled on the left end part of the main shaft sleeve; and space cams are assembled on the end cover through a cam regulating rod sleeved with a first pressure spring, positioned on the right ends of the two push rod shaft shoulders and in contact fit with each other. The device has small energy loss and small leakage, prevents a pipeline from intertwining and can be precisely controlled to spray or stop spraying spray a fertilizer.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a liquid fertilizer fertilization operation assembly on a fertilization machine that can realize the non-inflection point transportation of liquid fertilizer, prevent fertilizer road winding, and realize liquid fertilizer spraying and spray stop control. Background technique [0002] In agricultural production, because the use of liquid fertilizer has many characteristics such as green environmental protection, high nutrition, high concentration, fast absorption, good stability, strong stress resistance, wide application range, and harmless to humans and poultry, it is widely used in wheat, rice , corn, soybean, tea, tobacco, flowers, Chinese herbal medicine and other crops are widely used. However, due to structural design defects, there are many inflection points in the pipeline systems on various liquid fertilizer fertilization machines, and the energy loss is large. Slender hos...

Problems solved by technology

However, due to structural design defects, there are many inflection points in the pipeline systems on various liquid fertilizer fertilization machines, and the energy loss is large. Slender hose connections are required between them, and the energy loss is also relatively large. This kind of pipeline system requires relatively high pressure when the amount of fertilizer applied is satisfied, and the requirements for the sealing performance of the pipeline are relatively strict, and the energy consumption is also relatively large.

At the same time, there are many leakage points in the existing pipeline system and distributors, which not only cause the loss and waste of liquid fertilizer, but also for precision agriculture, the leakage of fertilizer also has a great impact on the accuracy of fertilization

In addition, the existing tie-up mechanism has two fertilizer spraying needles, and two hoses are led out from the tail ends of the two fertilizer spraying needles, and the hoses will be entangled during the movement of the mechanism
