Description

one

The invention relates to agriculture, and B in particular to the mechanization of labor-intensive processes of transhumance. It can be used in water-lifting equipment, for example, for raising water from bulk wells.

The belt water lifter is known, which includes a water-saturated endless belt, drive pulleys, a release roller and a tension roller.

A disadvantage of the known belt water lifters is that during operation in the saturation zone, fresh and salty or contaminated water layers are displaced due to belt movement. This leads to general salinization or contamination of the water being raised.

The purpose of the invention is to prevent the mixing of fresh and salt water when water lifting.

This is achieved by the fact that the proposed water lifter is provided with a tank covering the water intake part, made, for example, in the form of a cylinder with a closed cone-shaped bottom and a liter of spillway located above the level of salt water.

The installation of such an orifice cylinder avoids the movement of water layers in the zone of water saturation of the tape, because only fresh water (from the upper layers) can flow through the water intake holes.

The drawing schematically shows a belt water lift.

The main working body of the water lifter is an endless belt consisting of two layers. One of them, bearing, of rubberized material 1, the other - of porous material 2. In the upper water intake

parts of the drive pin 3, and in the lower, water-saturated - driven pulley 4.

In order to squeeze water out of the tape, roller 5 is placed in the upper part, roller 6 in the lower part to remove air from the cells of the porous mass for better water saturation of the tape. The container 7 encloses the pulley 4 and the roller 6 and at the same time serves to tension the belt, since the bottom of the container is filled with ballast 8. The container in the upper part of the walls has weirs 9.

Water lift works as follows.

The downward ve, the water lift of the driving pulley 3 is directed to the tank 7.

enters it and passes through the grooves of the pulley 4 and the roller 6. At the same time, the air present in the pores of the tape 2 is pressed out, which contributes to its better water saturation. Rising branch, the passage between Shchik 3 and roller 5,

pressed from the water, the cycle is repeated. Water from the water lifter

iKocTb for storage and distribution. As far as the fresh water is flowing, the pure water surrounding the upper part of the cylindrical tank 7, through the springs 9, replenishes the tank.
