How to clean the self-propelled orchard sprayer after use? Posted by : admin / Posted on : Oct 22,2021

In the past, spraying fruit trees required manual spraying of pesticides on the back of the self-propelled sprayer in hot weather, but now, there are various self-propelled sprayers in the fruit tree farmland to replace the tedious work of manual spraying. The equipment not only improves the spraying efficiency, but also avoids heat stroke caused by high temperature in the manual spraying process. It can also solve the problem of common insects in fruit trees. The operation of the self-propelled sprayer of Heilongjiang Garden Machinery Factory is relatively simple and practical, but these preventive measures must not be sloppy when used.

1. We must first understand the type of self-propelled sprayer
There are self-propelled, suspended, towed, suspended and towed, all of which require tractors as auxiliary power. The former is economical and practical and has strong mobility, while the latter has good climbing ability. It is also suitable for densely planted or inclined orchards.

2. Understand the structure of the self-propelled sprayer
The self-propelled sprayer is mainly divided into two parts: the power self-propelled sprayer. The spraying part is composed of liquid storage tank, fan, plunger pump or diaphragm pump, pressure regulating distribution valve, filter, suction valve, drive shaft and spray device. There are multiple nozzles on both sides of the nozzle, arranged in a fan shape, with adjustable spray range.

Does the self-propelled orchard sprayer need to be cleaned again? We all know that the main purpose of everyone buying a self-propelled orchard sprayer is to spray pesticides in the orchard to prevent pests, but the pesticides required for each pest control are different Can they be mixed? This becomes a problem. In fact, experienced fruit farmers know that self-propelled orchard sprayers must be cleaned after spraying, because if you forget to clean the bucket with herbicides, for example, spraying pesticides on other crops, it is easy to cause pesticide damage. So, how to clean the self-propelled orchard sprayer that was once a "herbicide"?

First of all, the self-propelled orchard sprayer that has been sprayed with herbicide (glyphosate) can be cleaned with mud water first, and then rinsed with water to remove the mud, it can be used, but we also need to know that the herbicide is different, you need to use it Different cleaning methods. At present, there are usually three herbicides on the market: water, suspension and emulsion, so you have to decide how to clean it correctly according to the type you are using, but the principle is almost the same, just use clean water or add some detergent, shake it up and down to Wash away the pesticide residues in the self-propelled orchard sprayer.

Of course, most pesticides are acidic. We can use the principle of acid-base neutralization and put some alkaline things, which also has a good effect. For example, put some edible alkali, which is what we often call baking soda. However, if you use special herbicides, it is recommended to wash with detergent: in fact, washing with water can achieve the effect of removing residues, but for herbicides such as paraquat (currently banned) or glyphosate, we can also use cleaning When preparing glyphosate solutions, soft water or very clean water must be used to ensure the effectiveness of the herbicide. Therefore, the self-propelled orchard sprayer that has used glyphosate can clean the residual glyphosate with turbid muddy water.

However, we also need to know that all herbicides must reach a certain concentration to be effective. It does not contain a small amount of ingredients that can cause phytotoxicity. However, it must be cleaned after use. If it is a self-propelled orchard sprayer, the method is similar to the above. The upper medicine bucket is bigger. You can pump in clean water with a hose, then use a mop or something that can be inserted into it to clean and wash it several times. In addition, there is a more troublesome method, which is to disassemble all the parts of the self-propelled orchard sprayer, put them into the self-propelled orchard sprayer with herbicide installed, and plug all the holes of the self-propelled orchard sprayer. , And then add about 50 degrees of alkaline water, wash them one by one, and then rinse with clean water. Although troublesome, the cleaning effect is very good.
