(5) The existing double-box fertilizer applicators have common defects, that is, the amount of fertilizer application cannot be precisely controlled: ① For the transport wheel-driven double-box fertilizer applicator, first of all, due to the influence of the transport wheel drive, the driving torque of the fertilizer discharge device Second, the amount of fertilization is proportional to the forward speed of the transport wheel, that is, the greater the tractor traction speed, the greater the amount of fertilization; otherwise, the smaller the amount of fertilization
On the one hand, the flow rate input to the motor is affected by the hydraulic output flow rate of the tractor; on the other hand, the throttling speed control circuit using a throttle valve is greatly affected by the load, and the speed rigidity is poor.
Therefore, it is also difficult to accurately control the amount of fertilizer applied by this type of fertilizer applicator.

The invention discloses a hydraulic circuit for an organic fertilizer and chemical fertilizer proportioning fertilization device and belongs to the technical field of hydraulic transmission of agricultural machinery. The hydraulic circuit comprises a hydraulic oil source, an oil tank, a group of multiple directional control valves, a speed control valve of an organic fertilizer ejecting shaft, a speed control valve of a chemical fertilizer ejecting shaft, a hydraulic drive motor of the organic fertilizer ejecting shaft, a hydraulic drive motor of the chemical fertilizer ejecting shaft, a hydraulic drive motor of an organic fertilizer stirring shaft, a hydraulic drive motor of a chemical fertilizer stirring shaft, and the like. When the fertilizing amounts of the organic fertilizer and chemical fertilizer are subjected to proportioning control, the first reversing valve and the second reversing valve of the multiple directional control valves are both positioned at a right position; the valve core opening degrees of the speed control valve of the organic fertilizer ejecting shaft and the speed control valve of the chemical fertilizer ejecting shaft are respectively adjusted, so that the proportion of the two opening degrees is consistent with the agronomic requirements on the fertilizing amount proportioning of the organic fertilizer and chemical fertilizer; and therefore, the hydraulic circuit drives the load and respectively spreads the organic fertilizer and chemical fertilizer according to the expected proportion. The hydraulic circuit disclosed by the invention is applicable to mechanized operation of proportioned fertilization of the organic fertilizer and chemical fertilizer.
Description
technical field [0001] The invention relates to an agricultural fertilizing machine, which is a hydraulic circuit of a fertilizing device used for covering and sowing organic fertilizer and chemical fertilizer according to the ratio before plowing. Background technique [0002] Before plowing, surface fertilization is an important part of agricultural production. Over the years, "fertilization based on experience" has caused the following consequences: more chemical fertilizers, less organic fertilizers, more nitrogen fertilizers, less potassium fertilizers, more three-element fertilizers, less trace elements, and an imbalance in the ratio of nitrogen, phosphorus, and potassium. Apply a certain amount of organic fertilizer to the cultivated land every year to improve the content of organic components in the soil, so that the organic components in the fertilizer can play a role in the cultivated land, so as to meet the nutrient standards for land planting. Before plowing the...
