Currently, China's pesticide production technology has been in international most advanced level, but pesticide spraying technology still falls behind, and pesticide utilization rate is most
High less than 30%, not only peasant economy is impaired, and main pesticide residue is high, and pesticide volatilization causes atmosphere pollution, pollutes again into soil
Water resource.With the rapid development of electronic technology and the modernization requirement of precision agriculture, conventional application has been unable to meet agricultural
The demand of production, accuracy pesticide applying technology are just come into being.
(3) summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of structures simply, pesticide wastes less, the change that work efficiency is high
Measure sprayer controller.
The present invention is achieved through the following technical solutions:
A kind of Variable rate sprayer controller, including the vehicle frame being mounted in front wheels and rear wheels, it is characterised in that: installed on the vehicle frame
There are engine, instrument board, gearbox and medicine-chest, engine connects transmission shaft by gearbox, before transmission shaft passes through driving respectively
Bridge connects front wheels and rear wheels with driving rear axle, and farm chemical spray pump, the medical fluid conveying that farm chemical spray pump passes through installation distributing valve are equipped on medicine-chest
Pipeline connects bar spray assembly, and vehicle frame front end is equipped with spray boom support, and bar spray assembly is erected on vehicle frame and spray boom support；Transmission shaft
Velocity sensor nearby is installed, is separately installed with flow sensor, electric control valve, medicine on the medical fluid conveyance conduit of distributing valve end
Liquid level sensor is installed in case, master control display is installed on instrument board, master control display is separately connected velocity sensor, stream
Quantity sensor, electric control valve and liquid level sensor.
The present invention passes through key-press input type spray boom breadth, unit area formulation rate setting value on master control display, vehicle
Velocity sensor, flow sensor, liquid level sensor acquire on time, monitor, show relevant parameter after starting；Master control display is fixed
When the actual value of unit area formulation rate is compared with setting value, automatically adjust the electric control valve that is mounted on pipeline and open
Degree, the variation for the pipeline flow that causes to spray, keeps the effective unit area formulation rate consistent with setting value, precisely sprays to reach
Purpose.
More excellent technical solution of the invention are as follows:
Power supply on the instrument board connects master control display, provides power supply for control device.
The driver's seat being equipped between instrument board and medicine-chest on the vehicle frame is equipped with corresponding driver's seat on vehicle frame
Ladder realizes up and down action of the driver on vehicle frame by ladder.
Warning device is installed on the master control display, when exception occurs in spraying control, as the liquid level of medicine-chest reaches alert
Indicating value, master control display issue warning note.
The configuration of the present invention is simple, rationally, the improvement and installation easy to accomplish on original machine, cost performance is high for design, avoids
Artificial adjusting distributing valve, extends the service life of valve, effectively reduces the amount of labour of operator, reach adaptation to local conditions precisely by
Amount application, economizes on resources, and reduces pollution.
(4) Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is control structure schematic diagram of the invention.
In figure, 1 vehicle frame, 2 front-wheels, 3 rear-wheels, 4 engines, 5 instrument boards, 6 gearboxes, 7 medicine-chests, 8 transmission shafts, before 9 drivings
Bridge, 10 driving rear axles, 11 farm chemical spray pumps, 12 distributing valves, 13 bar spray assembly, 14 spray boom supports, 15 velocity sensors, 16 flow sensings
Device, 17 electric control valves, 18 liquid level sensors, 19 master control displays, 20 ladders, 21 power supplies.
(5) specific embodiment
Attached drawing is a kind of specific embodiment of the invention.The embodiment includes the vehicle frame 1 being mounted on front-wheel 2 and rear-wheel 3, described
Engine 4, instrument board 5, gearbox 6 and medicine-chest 7 are installed, engine 4 connects transmission shaft 8 by gearbox 6, passes on vehicle frame 1
Moving axis 8 connects front-wheel 2 and rear-wheel 3 by bridge 9 before driving and driving rear axle 10 respectively, is equipped with farm chemical spray pump 11 on medicine-chest 7, sprays
Pump 11 connects bar spray assembly 13 by the medical fluid conveyance conduit of installation distributing valve 12, and 1 front end of vehicle frame is equipped with spray boom support 14, sprays
Bar assembly 13 is erected on vehicle frame 1 and spray boom support 14；Transmission shaft 8 is nearby equipped with velocity sensor 15,12 end medicine of distributing valve
It is separately installed with flow sensor 16, electric control valve 17 on liquid conveyance conduit, liquid level sensor 18, instrument are installed in medicine-chest 7
Master control display 19 is installed, master control display 19 is separately connected velocity sensor 15, flow sensor 16, electronic on dial plate 5
Regulating valve 17 and liquid level sensor 18；Power supply 21 on the instrument board 5 connects master control display 19；On the vehicle frame 1
The driver's seat being equipped between instrument board 5 and medicine-chest 7 is equipped with the ladder 20 of corresponding driver's seat on vehicle frame 1；The master control
Warning device is installed on display 19.
Spraying device of the invention, first inputs each setup parameter before activation, spray boom state (standard-sized sheet, half-open, fold), often
Mu spray value setting value, pressure valve initial value, operating speed, valve original state；Machine startup initialization is online to be entered normally
After job state, master control system carries out judgement comparison according to velocity sensor 15,16 timing acquiring data of flow sensor: practical
Whether spray value is consistent with its setting value per acre.If machinery operation velocity perturbation, reality spray value stream per acre is detected according to the time period
When amount is more than setting value allowable error range 5%, master control system can issue the opening size of instruction control electric control valve 17, make
Its index is in spray value setting value normal range (NR) per acre.And master control system also acquires the signal of liquid level sensor 18 on time,
It will call the police prompt operator when being lower than liquid level warning value.19 panel button of master control display of master control system selects pesticide
Not, screen display can input spraying swath width, setting spray value per acre, at any time Dynamically Announce current time, travel speed, spray tank liquid level
And the data such as practical spray value per acre, accumulative spray area are, it can be achieved that manual/auto, data accumulation/clearing conversion function.
