Fertile machine is penetrated in soil by hole pricking mechanism and is able to achieve the depth of liquid fertilizer and applies, is chiefly used in intertillage fertilising, it may appear that injury seedling phenomenon；I
A kind of liquid fertilizer bundle cave applicator structure is disclosed in state patent No. ZL107580846, drives bundle cave to apply with note using crank rocker
Linkage integrated machine structure complete to prick cave and liquid fertilizer infuse apply synchronize work continuously.Existing liquid fertilizer applies machine deeply and has been applied to plant more
The field on ground is grown, and for applying the still unmanned research at present of liquid fertilizer equipment in the relevant depth of seed sowing stage, study table
It is bright, a certain amount of special liquid fertilizer is applied around each seed when planting seeds, seed can be promoted in teething and early growth period
Obtain enough nutritional ingredients, the effect that the good plant of seedling growth more can obtain high yield, increase income.It is this at seeding time with regard to carry out
The fertilizer application mode that liquid fertilizer essence is applied is the trend of future development, it can make plant early growth period just obtain enough nutrition at
Point, and the waste of liquid fertilizer is applied and reduced to the essence for being able to achieve liquid fertilizer, and the key component of this fertilization mode is exactly proportioning device,
How suitable liquid fertilizer accurately is provided for each seed.
Therefore it needs a kind of using differential gear train and cam follower mechanism, rotor per revolution, to fertilizing mechanism offer
A certain amount of liquid fertilizer, to realize that the quantitative essence of liquid fertilizer is applied, reach accurate fertilizing, reduce waste, reduce environmental pollution and
Save the purpose of production cost
