The sprayer is a kind of agricultural machinery that disperses liquid, and it is a kind of agricultural pesticide application machinery. The plant protection machinery in agricultural machinery belongs to portable agricultural machinery. It is also called high stem crop sprayer or field bath sprayer. Sprayer [suitable for pest control in forests, nurseries, orchards, tea gardens, cotton, wheat, rice, corn and other field crops and large-scale pastures, garden flowers and trees in cities and suburbs, vegetable gardens, and plants in greenhouses. Prevention and treatment.
   The smaller the particle size of the smoke, the more the number of fog particles. Experiments have shown that the more fog particles per unit area, the better the control effect. A large number of mist particles diffuse in the space and distribute evenly, which greatly increases the chance of contact with germs and pests, and is beneficial to improve the control effect. The smoke particles are small and have multi-directional deposition characteristics. It is beneficial for the fog particles to deposit on the front and back of the branches and leaves and in all directions of the insect body. The deposition rate is higher on small targets, such as insect antennae and hairs. This is the effect of pest control. One of the good reasons.
 

 

 Common failures and troubleshooting methods
 Difficult to start-up
1, lgnition needle does not work or high voltage coil is damagedWhen the machine is difficult to start, check the test power first, to checkwhether there is squeak sound when the needle works. lf there is no sound, itmeans that the ignition needle or high voltage coil is damaged. in this case.remove the cap on the carburetor first, and then remove the ignition needle withthe sleeve, check whether there is carbon deposition on the ignition needle.When carbon deposiion is found, grind it with sand paper. After grindingfinished, reload needle to the machine, and check the test power again. If theignition needle still does not work, check the battery condition, cables and highvoltage package. Before the high voltage coil is checked, remove the cap, placethe high voltage cable at a distance of 2mm away from the machine to test thepower and high voltage package. lf it is not ignited, check if the cable is loose orfall off. lf the cable is not loosed or fall off, replace high voltage coil. lf the ignitionis weak, it shows the electricity is insufficient, please charge the battery.2, The diaphragm damage of carburetorAfter a long time operation, if the machine is not easy to start, please checkthe carburetor diaphragm. Remove the plastic protective cover and thecarburetor screws, take out the diaphragm assembly and check the diaphragm.If it is damaged, please change it.
Note: when the diaphragm is changed, don't put it into wrong position.
Remember the order when you demolish it, and install it in reverse order.

IIl. Composition and working principle
1, The machine is mainly composed of four parts: water circuit, electrical circuit,gas circuit and fuel circuit, including carburetor, engine and explosion tube, frame.fuel tank, pesticide tank and pipeline.2, Working principle:
Fogging machine uses gasoline as fuel, when it is started, the high temperatureand high pressure's gas flow at high speed generated by the engine sprays fromthe pulse nozzle. When the pesticide valves is opened, the pressure in thepesticide tank presses the drug into the pipe to meet the high temperature andhigh speed flow. At the moment of meeting, the drug solution is atomized intosmoke and jetted out from the nozzle, and quickly spread and diffuse. When theobject is exposed to the mist or smoke, it will be killed.

The machine cannot be filled with highly corrosive chemicals, such as peracetic acid, chlorine dioxide, etc. Except for alcohol, other sterilization and disinfection liquids can be used.

The battery can be recharged only when it is started. Gasoline is used to provide power for the machine. Gasoline should be 93 pure gasoline added to the gasoline tank, and diesel is added to the medicine box to assist in the production of smoke and smoke aids.

Pulse machines are different from two-stroke and four-stroke machines.
1: When there is gasoline in the oil pipe and there are oil bubbles, do not press the oil bubble multiple times. When the start button does not start after long pressing, you can only press the oil bubble and press it again.
2: Do not press the start button intermittently, press and hold it.
3: Gasoline must be pure gasoline. Discolored gasoline, gasoline stored in plastic barrels for a long time, and mixed oil cannot be used.
