Description
Technical field
The present invention relates to agricultural engineering technology fields, specifically, are related to a kind of modified greenhouse list hanger rail self-propelled air
Send boom sprayer.
Background technique
It is generally smaller that China's facilities vegetable plants line space, the in the ranks further constriction in space after plant growth, furthermore in the ranks
Soil conditions are complicated, are not suitable in the ranks being sprayed equipment operation.Hanger rail type spraying machine mobile operation above crop in greenhouse is not take up
Ground space improves greenhouse space utilization rate.Spraying machine is hit exactly from greenhouse to two sides above crop simultaneously sprays, compared with canopy side
Track spraying machine, to other side spraying operation, sprays working width and halves from the sidewalk of canopy side, and droplet deposition uniformity is into one
Step improves.Greenhouse especially sunlight greenhouse structure is complicated, trellis supports column and is arranged in above crop supplemental crop growth in length and breadth
The hanging tendril rack of intertexture, limits the spray bar length of spraying machine, uses air-assisted spraying technology that can meet with shorter spray bar length
Realize biggish spraying swath.On the other hand for the spraying operation droplet high up in the air of the tall and big crop in greenhouse for crop canopies middle and lower part
Penetrance, deposition, uniformity are all insufficient, and crop hat can be effectively increased by the ranks being sprayed using lifting type spray boom immersion crop canopies
Layer middle and lower part Droplet deposition, improves middle and lower part penetration of droplets rate and deposition.
A kind of track disclosed in Chinese patent application No. is 201810073358.5 is from walking multimode greenhouse auto spraying
Machine discloses a kind of single hanger rail based on i-beam track from walking multimode automatic sprayer.The device using I-steel as track,
And running gear is developed based on I-steel, crop is immersed by lifting type spray boom and in the ranks implements spraying operation, lifting device is adopted
Use stepper motor combination synchronous belt slide unit as solution.Meanwhile wind send the wind regime of spray boom by be fixed on the rack from
Heart blower provides, and send through vent hose to spray boom and realizes air-assisted spraying.Substantially track and movement are solved, spray lance lifting, with
And the operation function of air-assisted spraying.It is primarily present following problems: being that I-steel and its driving device quality are big first, cost
Height, difficulty of construction is big for track installation, is unfavorable for device application；Secondly, the mobile side of stepper motor combination synchronous belt slide unit
Though case has the advantages that elevating movement is accurate, cost and maintenance cost are high, are also unfavorable for the application of device；Furthermore wind is sent
System is using fixed centrifugal blower, the embodiment for sending airflow to spray boom by vent hose.One side air-flow is in vent hose
Middle generation linear loss, another aspect spray boom move up and down when be bound to cause the bending of ventilation shaft, further increase air-flow
Local losses, and hose alternating bending is straightened, and air-flow local loss coefficient is caused to change, and then keeps stream pressure and flow velocity unstable
It is fixed, to influence spraying operation effect.
