Problems solved by technology

The fertilizer applicator has the following disadvantages: (1) It uses a hydraulic motor as the drive element, requiring the supporting tractor to provide a hydraulic drive system with a large capacity, while for ordinary small and medium-sized tractors, it is necessary to design another set of supporting hydraulic system, which limits the fertilizer applicator. The ability to match with tractors makes it only suitable for use with some tractors; (2) The adjustment of fertilization amount is only adjusted by the hydraulic motor to drive the rotation speed of the fertilizer applicator, which makes the adjustment accuracy and variation range of fertilization amount small

Description

technical field [0001] The invention relates to equipment in the technical field of agricultural machinery, in particular to a seeding and fertilizing machine with dual adjustment of opening speed and precise variables. Background technique [0002] As a revolution in agricultural production, chemical fertilizers have greatly increased the yield of agricultural products, but on the other hand, excessive use of chemical fertilizers will also change the soil structure and even cause damage to the environment. In the same plot, some places have high soil nutrients and some places have low soil nutrients. If the whole plot is fertilized according to the same amount, some places will be under-fertilized and some places will be over-fertilized. Part of the excessive use of chemical fertilizers will be dissolved and infiltrated into groundwater, causing environmental pollution. With the strengthening of people's awareness of environmental protection, the requirements for sustainab...
