Precise sowing technology is an agricultural year culture technique, and precise sowing can not only be saved a large amount of elite seeds and thinning labour, is evenly distributed but also have seed, is conducive to plant growth, is convenient to the advantages such as do mechanization operation.Air-suction type accurate sower is the crucial farm machinery of realizing precise sowing, has the features such as speed of drilling is fast, adaptation seed ability is strong.
Air-suction type accurate sower is to produce negative pressure by blower fan, and negative pressure is offered to air-suction seeding unit, mainly completes precise sowing by air-suction seeding unit.The negative pressure that blower fan produces is directly proportional to rotation speed of fan, and rotating speed is too fast, produces negative pressure too high, when seeding operation, easily produces and replays; Rotating speed is excessively slow, produces negative pressure too low, easily produces broadcast leakage; Rotation speed of fan is the key parameter that determines seeding quality thus.And, in the time of air-suction type accurate sower sowing Different Crop, the negative pressure difference of required optimum sowing, therefore, rotation speed of fan should be convenient to regulate.
At present, the blower fan of air-suction type accurate sower adopts cross coupler to be connected with tractor motive power output shaft, the shortcoming that adopts this mechanical connection manner is when tractor seeding operation is to field, tractor throttle diminishes, tractor motive power output shaft rotating speed reduces, easily produce broadcast leakage, and in the time of sowing Different Crop, rotation speed of fan cannot effectively be adjusted, cause seeding quality to decline, due to the problem in structural design, the fan transmission system of said structure can not meet the needs of high-quality precise sowing, cannot realize the adjusting of rotation speed of fan, reduce seeding quality.
Summary of the invention
The utility model provides a kind of air-suction type accurate sower blower fan hydraulic drive mechanism, the nonadjustable problem of rotation speed of fan existing for solving prior art.
The technical solution of the utility model is: a kind of air-suction type accurate sower blower fan hydraulic drive mechanism, comprises hydraulic power unit, in-line snap joint 5, oil return line snap joint 6, flow speed control valve 7, blower fan 8, shaft coupling 9, hydraulic motor 10; Wherein the two ends of in-line snap joint 5 are connected with the oil-out of hydraulic pump in hydraulic power unit 3 and the oil-in of flow speed control valve 7 respectively, hydraulic pump 3 is communicated with by in-line snap joint 5 with flow speed control valve 7, the oil-in of hydraulic motor 10 is connected with the oil-out of flow speed control valve 7, the two ends of oil return line snap joint 6 are connected with the oil return opening of hydraulic oil container 1 in the oil-out of hydraulic motor 10 and hydraulic power unit respectively, and hydraulic motor 10 is connected with blower fan 8 by shaft coupling 9.
Described hydraulic power unit comprises hydraulic oil container 1, filter 2, hydraulic pump 3, overflow valve 4; The oil-in of its middle filtrator 2 is connected with the oil-out of hydraulic oil container 1 and the oil-in of hydraulic pump 3 respectively with oil-out, and the oil-in of overflow valve 4 and oil-out are communicated with the oil-out of hydraulic pump 3 and the oil return opening of hydraulic oil container 1 respectively.
The air inlet of described blower fan 8 is connected with air-suction seed metering device.
Use procedure of the present utility model is: when operation, hydraulic oil in hydraulic oil container 1 passes through filter 2, hydraulic pump 3 successively, part constant flow fluid enters in hydraulic motor 10 through in-line snap joint 5, flow speed control valve 7, drive hydraulic motor 10 to rotate, drive blower fan rotation by shaft coupling 9, rotation speed of fan is constant, produces and stablizes negative pressure, and the fluid of another part is through 4 times hydraulic oil containers 2 of overflow valve.
In the time sowing the another kind of crop of required different negative pressure, by adjusting flow speed control valve 7, change the hydraulic fluid flow rate that enters hydraulic motor 10, change the negative pressure of rotation speed of fan and generation, for air-suction seeding unit provides suitable negative pressure, can realize high-quality precise sowing.
The beneficial effects of the utility model are: by the hydraulic system on utilization and air-suction type accurate sower matching tractor, adopt flow speed control valve, hydraulic motor combined fan hydraulic drive mechanism, realize that rotation speed of fan is adjustable, high-quality precise sowing, have simple in structure, reasonable in design, degree of regulation is high, easy to use, the reliable feature of operation.
