Description
Technical field
The utility model relates to a kind of agricultural machinery device, mainly is a kind of variable fogdrop diameter sprayer.
Background technology
At present in equipment for plant protection is precisely sprayed research and use; Need obtain the spray amount of plant growing density and corresponding change equipment for plant protection in real time; Reaching the purpose of killing damage by disease and insect with optimum spraying dosage, to avoid excessive dispenser to doing the deposits yields poisoning and dispenser causes environmental pollution to environment.
China agricultural producing region, chemical pesticide has become topmost pollution source to the pollution of environment.Seriously restricting agricultural sustainable development and the physical and mental health that influences the people.This is one of the main reasons wherein, is that the equipment for plant protection product falls behind, (particularly the manual sprayer quality problems are more outstanding) with low quality, improper use, has increased the weight of the chemical pesticide environmental pollution greatly.With regard to the present situation of present China, completely forbid the production and the use of chemical pesticide, the condition of every aspect does not still possess, and plant protection for a comparatively long period of time, will continue to rely on chemical pesticide.Adopt few agricultural chemicals of trying one's best so; Reach the purpose of plant protection, develop new equipment for plant protection product, do not make chemical pesticide drippage ground in the use as far as possible; Utilize image processing and pattern recognition; Set up intelligence control system, the control fogdrop diameter changes with plant growing density is different, improves the availability and the pollution of minimizing chemical pesticide to environment of chemical pesticide from the source of equipment for plant protection.Simultaneously, utilize adjustable frame that sprayer unit is installed, can control spray direction like this, avoid spread of spray to enlarge and the pollution that causes.
The agricultural spray device of current domestic and international use, the atomizing disk sprayer unit, the air-assisted spraying device that use centrifugal spray device, two-phase flow sprayer, direct current generator to drive basically.Single centrifugal spray device fogdrop diameter can not arbitrarily change, and can only spray on the crop canopies blade face, and agricultural chemicals drippage ground is also very serious in the face of the pollution of environment; Two-phase flow sprayer, single sprayer unit fogdrop diameter can not arbitrarily change, and also can only spray on the crop canopies blade face; The atomizing disk sprayer unit that direct current generator drives belongs to the ultra low volume spray device, and fogdrop diameter is less, and the field is used and is prone to drift; The air-assisted spraying device, the spraying uniformity is relatively poor, and agricultural chemicals drippage ground is arranged.Therefore invention is suitable for the accurate sprayer unit of spraying of equipment for plant protection has become the task of top priority.
The utility model content
The utility model technical problem to be solved provides a kind of variable fogdrop diameter sprayer; It utilizes cantilever that sprayer unit is installed; Can adjust spray direction, thereby reduce spread of spray, simultaneously the size and the air quantity of the single sprayer unit fogdrop diameter of controlled; Make droplet drip ground less as far as possible, reduce pesticide pollution.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of variable fogdrop diameter sprayer includes frame and liquid case, and the frame two ends are separately installed with folding left and right cantilever, is connected with cable wire between the upper end of described left and right cantilever and frame, and described liquid case is fixed on the tractor; Be symmetrically installed with a plurality of sprayer units on the described left and right cantilever; Be provided with the feed liquor pipeline in the described sprayer unit, an end of feed liquor pipeline is connected with atomizing disk, and described atomizing disk stretches out outside the sprayer unit; Position facing atomizing disk is provided with blower fan; The air outlet of said blower fan faces atomizing disk, and described feed liquor pipeline is communicated with the liquid case, is connected with magnetic valve on the said feed liquor pipeline.
Be useful on the hitch that is suspended on the tractor on the described frame; Camera also is installed on the frame.
Described atomizing disk, blower fan be by motor-driven, magnetic valve by control circuit through pulse width modulation controlled.
Described blower fan can be by pressure-air pump, ventilation duct, magnetic valve and air nozzle replacement.
Formed sprayer unit by motor-driven atomizing disk, motor-driven blower fan, magnetic valve, control circuit, feed liquor pipeline etc. in the utility model; The soup that gets into through the feed liquor pipeline flows to motor-driven atomizing disk atomizing through magnetic valve, and the droplet that atomized simultaneously receives by motor-driven blower fan wind drive and floats towards crop blade face, crop bottom and the crop leaf back side; Described sprayer unit is single sprayer unit medicinal liquid flow, air quantity, atomizing disk rotating speed to be controlled in real time according to the stand density of the crop of camera production by host computer control system.
Atomizing disk, blower fan, motor speed are controlled by control circuit in the utility model, and motor speed is high more, and the fogdrop diameter of atomizing disk atomizing is more little; Motor speed is high more, and fan delivery is big more.The fogdrop diameter of atomizing disk atomizing can change between the 10-90 micron, and fan delivery also has an excursion; Magnetic valve through pulsewidth modulation (PWM) control, is controlled the make-and-break time of magnetic valve by control circuit in addition, controls flow to the medicinal liquid flow of motor-driven atomizing disk; Motor speed is high more, and medicinal liquid flow is more little, and the fogdrop diameter of atomizing disk atomizing is more little, otherwise fogdrop diameter is big more.Be provided with one chip microcomputer and RS485 and host computer communication interface in the control circuit, single sprayer unit makes things convenient for PC control.Fan assembly can be by pressure-air pump, ventilation duct, magnetic valve and air nozzle replacement, and it is inner with pressure-air droplet wind to be sent into the plant plant, prevents float of mist droplet, changes the magnetic valve make-and-break time, can change the air quantity size.This sprayer unit can reach following performance:
1. fogdrop diameter changes at 10-90 μ m;
2. the drift distance of droplet under 3-fresh breeze is less than 3-5M;
3. droplet drippage ground is less;
4. single sprayer unit spraying swath is 1.5 meters;
5. comparable existing manual sprayer is practiced thrift 1/3 left and right sides agricultural chemicals and is reached its same control efficiency;
6. according to the variation of cropping intensity, the size and the air quantity of the single sprayer unit fogdrop diameter of controlled make droplet drip ground less as far as possible, reduce pesticide pollution.
The utility model has the advantages that:
The utility model utilizes cantilever that sprayer unit is installed, and can adjust spray direction, thereby reduce spread of spray, and the size and the air quantity of the single sprayer unit fogdrop diameter of controlled make droplet drip ground less as far as possible simultaneously, reduces pesticide pollution.
