Problems solved by technology
Existing liquid fertilizer applicators mainly use rotary drive fertilizer spraying needles to achieve alternate hole piercing. The driving part is an irregular gear planetary system with high processing precision and complex equipment. Especially when this planetary gear system is used as the driving part, the equipment cannot The vertical posture of the fertilizer spray needle and the realization of horizontal zero-speed piercing holes, the hole openings appearing on the ridge surface are large, which eventually leads to serious volatilization of liquid fertilizer, which affects the absorption and growth of liquid fertilizer by crops, and pollutes the environment

The invention relates to a hydraulic driven type vertical and horizontal zero-speed pricking hole fertilization mechanism and belongs to agricultural machinery. A cylindrical chute type cam is mounted on a movable rack, a drive chain wheel is fixedly mounted on the cylindrical chute type cam, a slide rack is assembled on the movable rack, one end of the slide rack is inserted into an arc-shaped slide slot of the cylindrical chute type cam, a fertilizer spraying needle assembly is assembled on the lower portion of the slide rack, a bent pushing plate is fixedly mounted on the lower portion of the inner side of the movable rack, the bent pushing plate and a fertilizer spraying switch column on the fertilizer spraying needle assembly are in contact fit or out-of-contact fit, a hydraulic drive system is composed of a hydraulic oil tank, a hydraulic oil pump, a speed control valve, a reversing valve and a two-way hydraulic oil cylinder, and an action control system comprises a speed measurement sensor and a central controller. The mechanism realizes vertical and horizontal zero-speed pricking hole liquid fertilization application, and is simple in structure, high in automation level, strong in applicability, good in working quality, reliability in usage and high in liquid fertilizer usage efficiency.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a vertical and horizontal zero-speed piercing hole liquid fertilizer fertilization mechanism. Background technique [0002] The hydraulic fertilizer applicator is a working tool that applies liquid fertilizer deep into the soil and acts near the roots of crops. It has the characteristics of obvious fertilizer saving effect, increased production and income, and high economic and social benefits. Existing liquid fertilizer applicators mainly use rotary drive fertilizer spraying needles to achieve alternate hole piercing. The driving part is an irregular gear planetary system with high processing precision and complex equipment. Especially when this planetary gear system is used as the driving part, the equipment cannot The vertical posture of the fertilizer spraying needle and the realization of horizontal zero-speed piercing holes, the hole openings on the ridge surface are large, wh...
