Description

Application area

Manual ventilator sprayer refers to communal and agricultural machine-building and is used in horticulture, vegetable growing and in the care of various plantings in the communal sector.

State of the art

Known hand-pumped balloon type sprayers. Work with such sprayers is laborious and inefficient. Constant pumping is required, and a short torch of the solution cloud requires keeping the sprayer relative to the treated surface within 50 cm. Therefore, the sprayer has to bypass each branch working inside the crown. In this case, a lot of solution is inevitably wasted.

Disclosure of invention

The aim of this invention is the manufacture of such a manual sprayer, which will reduce the complexity, 2-3 times increase productivity and. more than 2 times reduce the flow rate of the solution.

This goal is achieved by the fact that the solution is pumped by means of a vibrating electric submersible pump equipped with a hose connecting the outlet pipe in series with a valve equipped with a pressure gauge and a pipe, and a cooling chamber mounted above the pump solenoid, and the electric motor or manual mower serves as a fan drive rotary type.

Brief Description of the Drawings

Hand-held fan sprayer.

1. Fig 1 - I - fan with a spray.

2. Figure 2 - II - supercharger.

The implementation of the invention

The sprayer consists of two main components: a fan with a spray gun I and a blower II.

The fan spray contains an electric motor 1, a fan 2 mounted on it, and a handle 3 made of light dry wood. In the center of the fan nozzle, a sprayer 4 is fixed, to which the solution is supplied through a hose 5 through a valve 6. Power to the electric motor is supplied by cable 7 through the switch 8.

As a fan drive, you can use rotary manual lawn mowers.

The supercharger II comprises a submersible pump 9 of a vibrational type, connected by a hose 10 to a pressure chamber 11 by a valve 12 and a cooling chamber 13, mounted above the pump electromagnet. The chamber 11 is equipped with a pressure gauge 14 and a hose 5 for supplying the solution to the sprayer 4.

The suction pipe 15 at the inlet has a mesh 16 for filtering the solution.

In order to create normal non-rigid operation of the pump, spring-loaded bearings 18 with rubber cushions, which rest on the bottom of the tank 20, are fixed on its body through rubber bushings 17.

In order to bring the suction pipe 15 closer to the bottom of the tank 20 in order to eliminate the “dead zones” that are not accessible for sparging, as well as to ensure that the pressure cuff “be constantly under the flood”, the pump in the tank 20 is installed upside down.

Sprayer operation

When the tank 20 is full, the sprayer operates as follows. The solution, passing through the filter screen 16, is pumped through a hose 10 to a chamber 11 through a hose 10, in which the valve 12 creates the required pressure, which is observed by a pressure gauge 14. The supplied solution flow into the chamber 11 is divided into a stream going to the sprayer 4 through a hose 5, and to the flow of excess solution going to the cooling chamber 13.

Since the intake of the solution to the nozzles 15 is carried out at the very bottom of the tank 20, and the excess solution is poured out of the chamber 13 above, then the solution circulates during operation, which ensures its constant mixing.

The solution, passing the sprayer 4, forms a cloud, which picks up the air flow created by the fan 2, and carries it to the crown of the tree.

If the length of the spray torch of a sprayed solution without a fan reaches half a meter, then the air flow of the fan stretches it to 4-5 meters, while increasing its diameter.

The proposed sprayer increases productivity by 2-3 times, reduces the flow rate of the solution by more than 2 times.

The author has been using the sprayer for more than 5 years. Manual fan sprayer can be widely used by individual gardeners and farmers.
