Abstract
The invention discloses a spraying swath controller of a spray rod type spraying machine. The spraying swath controller mainly comprises a control panel, an electromagnetic valve control circuit, spray head electromagnetic valves, overflow electromagnetic valves, throttle devices and a spraying machine pipeline system. One spray head electromagnetic valve is arranged in a front-end pipeline of each spray head in a series way and one overflow branch is arranged in each spray rod main pipeline correspondingly, and the overflow electromagnetic valves and the throttle devices are arranged in the overflow branches. During a drug delivery process of a farmland, the corresponding spray head is opened or closed through the control panel according to requirements, and the spraying swath of the spraying machine is adjusted, so that the respray phenomenon, the missed spray phenomenon and the out-of-range spray phenomenon are avoided. When the spray head electromagnetic valves are closed, the spray heads stop spraying medicine; the overflow electromagnetic valves in the corresponding overflow branches are opened simultaneously, part of liquid medicine flows to a liquid medicine box through the overflow electromagnetic valves and the throttle devices, and the pressure of the pipeline is stably kept. According to the spraying swath controller, the real-time adjustment of the medicine spraying swath is realized on the premise of ensuring the spraying effect, and the respray phenomenon, the missed spray phenomenon and the out-of-range spray phenomenon in a medicine application process at the present time are reduced.

At present, along with the development of science and technology, the use of large-scale agricultural machinery is inevitable, but the farmland of China is individual small-sized operation mainly, when using spray bar type spraying machine dispenser, due to the restriction on farmland shape size and border, often there is duplication and leakage dimension in spraying and ejection zone phenomenon.Respray and agricultural chemicals can be caused to waste, contaminated land, increases the weight of the phenomenons such as Practice for Pesticide Residue in Agricultural Products; Drain spray then can not effective disease and pest control, and ejection circle causes agricultural chemicals to waste and environmental pollution equally.In order to effectively avoid duplication and leakage dimension in spraying and ejection zone phenomenon, the present invention have developed a kind of spray bar type spraying machine spraying swath controller of Non-follow control, driver controls the duty of each road shower nozzle at the switch of driver's cabin by operation setting, effectively adjust the amplitude of spraying in real time according to farmland shape, improve the availability of agricultural chemicals, reduce the pollution of environment, meet the requirement of Eco-friendly sustainable development.
Summary of the invention
The object of this invention is to provide a kind of spray bar type spraying machine spraying swath controller, avoid duplication and leakage dimension in spraying and ejection zone phenomenon.In order to solve above technical problem, concrete technical scheme of the present invention is as follows:
A kind of spray bar type spraying machine spraying swath controller, is comprised pipeline portions, is connected to form successively, also comprise overflow system and control system by spray tank 1, filter 2, solution feed pump 3, shower nozzle magnetic valve 6 and shower nozzle 7 by pipeline; Overflow system by organizing overflow magnetic valve 5 and throttling arrangement 4 forms more, overflow magnetic valve 5 one end connects spray boom main line, one end connects throttling arrangement 4, the other end of throttling arrangement 4 is connected to spray tank 1 by pipeline, control system is made up of control panel 9 and plurality of electromagnetic valve control circuit 8 and indicator lamp 11, control panel 9 there are many groups two gauge taps 10 and indicator lamp 11, each group solenoid control circuit 8 controls a shower nozzle magnetic valve 6 and an overflow magnetic valve 5 simultaneously, and realizing two magnetic valve interlockings, indicator lamp 11 shows shower nozzle magnetic valve 6 on off state.
Solenoid control circuit 8 is made up of the relay of two anti-phase interlocks, wherein, the input stage of relay A14 and relay B15 seals in the loop, two contacts of two gauge taps 10 respectively, the output stage of relay B15 seals in the drive circuit of shower nozzle magnetic valve 6, and the output stage of relay A14 seals in the drive circuit of overflow magnetic valve 5.
Indicator lamp 11 seals in the input stage loop of relay B15, and shower nozzle magnetic valve 6 works, and indicator lamp 11 is bright, and shower nozzle magnetic valve 6 does not work, and indicator lamp 11 goes out.
Described relay can adopt solid-state relay, also can adopt ordinary electromagnetic relay.
Two gauge tap 10 rotation direction left sides on control panel 9, relay B15 connects, and shower nozzle magnetic valve 6 is energized work, and indicator lamp 11 is bright, and shower nozzle 7 is sprayed, and meanwhile, relay A14 disconnects, and overflow magnetic valve 5 cuts out; Time on the right of gauge tap 10 rotation direction, relay B15 disconnects, shower nozzle magnetic valve 6 cuts out, indicator lamp 11 goes out, and shower nozzle 7 stops spraying, simultaneously, relay A 14 connects, overflow magnetic valve 5 energising is opened, and in pipeline, part liquid flows into spray tank 1 through overflow magnetic valve 5 and throttling arrangement 4, and loine pressure remains stable.
the present invention has beneficial effect.The present invention is on the basis of common spray bar type spraying machine, set up control system, in spray process, driver can be as required, changed the spraying swath of spray boom by the gauge tap 10 operating driver's cabin in real time, effectively avoid duplication and leakage dimension in spraying and ejection zone phenomenon, improve agricultural chemicals availability, on the basis of effective disease and pest control, reduce pesticide pollution.Meanwhile, the overflow system that the present invention is arranged, after shower nozzle 7 stops spraying, the part liquid in pipeline flows into spray tank 1 through overflow magnetic valve 5 and throttling arrangement 4, stablizes the pressure in pipeline, ensures spraying effect.
