What is the daily maintenance that should be carried out on the knapsack motorized spray duster?

In the process of planting, we often have some serious diseases, at this time, the use of knapsack mobile spray duster can effectively allow us to kill insects in a large area, so that we can go further in the work of pest control. So many people who grow agricultural products will buy one such machine, but they do not get timely maintenance after use, resulting in damage to the machine, today I will teach you how to maintain the knapsack motorized spray duster.

Steps: When we use this machine, we need to put him in working condition, before dosing, we must first choose to spray it with clean water to make sure that his place is not infiltrated, and can spray all positions in all aspects. At the same time, we should not add too much when adding medicine, which will cause his nozzle to be blocked in front of it, and it will not be able to spray out the medicine. We also need to prevent the air outlet in the filter from entering our housing when we use it.

In the process of spraying, the liquid we use must be free of impurities, otherwise there will be some impurities blocking the air port and causing it to be unable to work.

After using the machine, we need to keep the space completely clean, and do not leave some powders or liquids. At the same time, we need to use water and rags to clean the dust on the surface, especially before use, we also need to wipe it more carefully. After he finishes work, we need to put it in a clean and dry vent, do not let direct sunlight shine for a long time it will cause damage to the machine.

PrecautionsWhen we are not using this machine, we need to open the lid of its medicine box to make sure it can be ventilated. If there is dust in the fuel, it will cause our machines to not work, so we need to clean the fuel system after use. After use, you also need to clean the air filter, wash the sponge body with gasoline, and then wring it out and put it in.

We also need to clean the steel heat sink frequently, because if there is a foreign object on it, it is easy to heat, if we use it to clean up weeds, we must clean it and then put it back to avoid problems in the next use.

Daily maintenance should be carried out, be sure to clean the spray holes, check whether the connection parts are loose, whether the screws are tightened, whether there is rust in the places that are easy to rust, and usually should be placed in a ventilated and dry place to prevent exposure.

Daily maintenance is actually to carry out some cleaning, but also to add lubricating oil in time, and do not use it for a long time, otherwise it will also cause its service life to be shortened.

Of course, daily maintenance should be carried out, and after the work is completed every day, it must be cleaned up in time.

Be sure to spray more lubricating oil to ensure the effect of the engine and ensure that the engine is flexible.

Yes, because it cleans and allows the spray duster to last longer and does a better job.

Table 8-5 shows Table 8-5 for the diagnosis of common congratulatory faults of knapsack spray duster and the removal method of Zen Mengkai.

Table 8-5 Diagnosis and elimination methods for common faults of knapsack spray duster.

Table 8-5 Diagnosis and elimination methods for common faults of knapsack sprayer (continued)-1

(1) Maintenance of spraying (sprinkling) parts.

After spraying, all parts should be scrubbed clean, and no residual liquid should be left in the medicine box.

After spraying, the powder door and the inside and outside of the medicine box should be cleaned.

When not in use, the lid of the medicine box should be opened.

After cleaning, run at low speed for 2 3min.

2) Maintenance of the fuel system.

Dust and water in the fuel are the main causes of engine malfunction, so the fuel system should be cleaned frequently.

There is residual oil in the fuel tank and carburetor, which will form glue and block the oil circuit for a long time, so the fuel should be drained when it is not used for a long time.

3) Maintenance of air filter and spark plug.

The air filter should be cleaned at the end of each day's work.

Clean the sponge with gasoline, wring it out and insert it again.

Remove the carbon deposit frequently, check its clearance, and the spark plug should be adjusted if it is too large or too small.

4) Maintenance of cylinder heat sink.

Clean the heat sink of the cylinder frequently, and the foreign matter plugged between the heat sink is easy to heat, so the weeds, mud, leaves and other foreign objects should be cleaned up in time. If the heat sink is thin, do not hit it with metal.

5) Long-term storage and maintenance.

Wipe the surface of the knapsack motorized spray duster and apply anti-rust oil to the metal surface.

Remove the spark plug, inject a small amount of oil into the cylinder, rotate the piston 4 5 times, stop at the top dead center, and then install the spark plug.

Pull off the nuts on both sides, remove the medicine box, clean the powder door and the inside and outside of the medicine box, then install the medicine box and tighten the nut.

Remove the nozzle, scrub it clean and store it separately.

All the fuel in the tank is drained.

Cover the knapsack electric sprayer with plastic film and store it in a dry and dust-free place.

As early as the mid-60s, a small number of plant protection machinery manufacturers in China began to develop and produce China's first generation of piggyback machine - WFB - 18AC piggyback machine with reference to the Japanese prototype of Brother Zheng. By the end of the 70s, there were three or four piggyback machine manufacturers in China, each developing piggyback machine products. The annual production and sales volume of the country has been maintained at tens of thousands of units.

After entering the 90s, with the support of national policies, the first peak year of demand for piggyback machines appeared in 1991 and 1992. The number of manufacturers has grown rapidly from five or six to more than 10. The enterprises that have developed after the development are mainly township collective enterprises, and the products are mainly WBF-18AC piggybacks.

Under the good development situation of the piggyback, the scientific research institute actively cooperates with the production enterprises, starting from reducing the operator's operating intensity, improving the fan structure and material of the WFB 18AC piggyback, and developing and producing a new generation of 18-type backpack machine - replacing the backward curved fan with a curved fan, replacing some ferrous materials with engineering plastics, reducing the size of the structure, reducing the weight of the whole machine, and improving the corrosion resistance. In addition, some large-scale piggyback machine manufacturers, while steadily improving product quality and output, continue to introduce and develop new piggyback machine products. At present, there are about 20 piggyback machine production factories in the country, with more than 10 varieties and an annual output of hundreds of thousands of units.

The piggyback machine is widely used in the pest control of agricultural and forestry crops in a large area, as well as chemical weeding, foliar fertilization, spraying plant growth regulators, urban sanitation and epidemic prevention, eliminating storage pests and livestock ectoparasites, spraying particles, etc. It is not limited by geographical conditions and is suitable for mountainous and hilly areas as well as scattered plots.
