If you see a guy with a wonderful rattling contraption behind his back, don’t be afraid, he just sprays trees from pests. The author was simply fed up with constantly breaking sprayers, and he decided to close up the sprayer on a gasoline engine. The kid did not trifle, he adapted the engine from a gas trimmer for these purposes. Of course, everything works flawlessly, the only problem is that a lot of excess weight appears, and the water in the sprayer sometimes weighs a lot. In general, the idea is worthwhile, only a gasoline engine can be replaced by a lighter electric one, moreover, it will be silent in comparison. Such a sprayer can easily paint over the fence. If homemade Interested in you, I propose to familiarize yourself with the project in more detail.
Materials and tools used by the author:
Material List:
- ;
- hoses;
- a sprayer;
- engine from trimmer;
- a cartridge from a drill;
- Sheet steel;
- self-tapping screws, screws, etc .;
- OSB or other similar material;
- a backpack and thick foam rubber.
Tool List:
- grinder;
- welding machine;
- vise;
- tape measure and marker;
- a screwdriver.
Homemade manufacturing process:
Step one. water pump
The author ordered a pump, they are designed to connect drills, based on them you can make pumps and other homemade products. This is possible, it will cost the least. The author tries to twist the pump shaft with a screwdriver, the pump works fine.
Step Two Engine
The author’s engine has a power of 1.25 kW, and it weighs as much as 8.3 kg, which is a significant minus of homemade work, it is better to find a motor easier. We remove the axis from the engine, and also unscrew the centrifugal clutch cover. We need to make an axis that will install the cartridge from the drill.
The author dismantled the shaft of the brushcutter and cut a piece of the desired length from it. An axis with a thread was then welded to this piece, onto which the drill chuck is wound. Centering, of course, is performed by eye. The author started the engine after installing the cartridge to make sure that there are no strong beats.
Step ThreeInstalling the engine and pump on the base
Next, we need to install all the prepared components on the basis, as such the author used a piece of OSB. To install the engine, we make a separate bracket from sheet steel, it is bolted with four screws, two in front and two in the back, which hold the gearbox cover and starter.
We also install the gas tank separately, the hoses can be easily replaced, we put longer ones.
We install the pump opposite the drill cartridge, clamp the pump shaft in the cartridge. We place a block or a board under the pump and fasten it with long self-tapping screws with washers.
Step Four Capacity
We install a container on the base, it needs to be fixed securely, since with water it can weigh all 10 kg. The main fastener is a metal sheet metal bracket that supports the bottom capacity. Also, the author draws a container to the base with a metal strip clamp.
We connect a hose to the pump, which will suck water from the tank and will supply it to the handle under pressure. The author fixes the hoses with hot glue, and fastens them to the base with metal plates.
Step Five Backpack and tests
The author puts the whole construction on his back, so we need a school or similar backpack. So that the OSB base does not press in the back, we attach a piece of foam rubber or other similar material. The author fastens the backpack to the base with self-tapping screws.
That's all, the homemade product is ready. We fill the tank with the necessary chemicals and go to kill all the pests, we are talking about insects, of course. We start the engine, the homemade product works fine, and you can work even at idle, because there is more than enough power here.
That's all, the project is over, I hope it prompted you to some useful reasoning. Good luck and creative inspiration, if you decide to repeat this. Do not forget to share your ideas and homemade things with us!
