Abstract

This invention relates to irrigation of agricultural crops, in particular, to drip irrigation. The purpose of the invention is to simplify the design and increase reliability. By supplying water to the irrigation pipe 11, it is communicated with the atmosphere due to the gap. A gap is formed in the conduit slot as a result of the fit of the ball valve 6 to the round hole 10. The gap is determined by the tension of the springs 9, the depth of the conduit slots and the water pressure in the pipe 11. The water entering the gap flows through the slot to the conduits the base of the ball valve 6. Then through an opening made in the bottom of the lid enters the root zone of plants. 6 Il.

Description

FIG. 2

The invention relates to the field of irrigation of agricultural crops, in particular to drip irrigation.

The purpose of the invention is to simplify the design and increase reliability.

FIG. 1 shows a dropper, general view, bottom; in fig. 2 - the same, front view; in fig. 3 - the same, side view; in fig. 4 shows section A-A in FIG. one; in fig. 5 is a section BB in FIG. one; in fig. 6 — node I in FIG. four.

The dropper contains a cap 1, made in the form of a hemisphere with holes 2 located one opposite the other on the wings 3 of cap 1. In the bottom part of the cap 1 there is also a round hole 4 and side openings 5. The cap 1 facilitates the lower part of the ball valve 6 made For example, from vulcanized rubber and secured in the lid 1 by means of pins 7 sealed at the bottom side of the valve 6, 7 entering into the side openings 5. Through the band 8 and springs 9 connected to the lid 1 the ball valve 6 fits tightly to a coal hole 10 located at equidistant distances in the lower part of the irrigation pipe 11. To adjust the tightness of the ball valve 6 to the round hole 10, a screw 13 is passed through the holes on the wings 12 of the tire 8 connected to the sleeve 14, which is connected to the threaded bore a pin 15 having an opening 16 in the end portion for securing the spring 9 therein. The bandage 8 facilitates the upper part of the irrigation pipe 11 located above the lower circular opening 10 therein. To ensure the required ode water drip chamber, the ball valve 6 has encircles its slot-conduits 17 downwardly of increasing depth that allows moisture to move freely in the valve abutment area 6 of cover 1 followed by the expiration of the available in the lid 1 of the bottom opening 4 the root zone of plants.

Dropper works as follows.

When water is supplied to the irrigation pipeline 11, due to the gap formed in the slotted conduit 17, as a result of adherence with one or another force of the ball valve 6 to the circular opening 10, the irrigation pipeline 11 is connected to the atmosphere and the possibility of water outflow from it. The size of the gap is determined by the tension of the springs 9, the depth of the slots of the conduits 17 and the pressure of water in the pipe 11. Water entering the specified gap flows down the slot of the m-conduits

17 to the base of the ball valve 6, from where through the bottom opening 4 of the cover 1 enters the root zone of plants. Since as the water drains down, the depth of the water slots 17 increases, they are blocked by mechanical impurities and free flow of water to the bottom opening 4 of lid 1 is achieved. Since the ball valve 6 is made of vulcanized rubber that has the properties of elasticity, the ability to deform and repair the original shape, then, by changing the pressure in the system, you can change the size of the gap in the slotted conduit 17 at the location of the ball valve 6 to the round hole 10 in the irrigation piping® water 11, which ox is adjusted in a wide range of flow characteristics dropper. If, however, the pressure in the system increases to a predetermined level, free flow of water from the irrigation pipe 5 may be possible, during which automatic drainage of the water lines 17 from mechanical impurities takes place. If necessary, the design of the dropper allows the possibility of manual adjustment of water flow. For this, rotate

0, the sleeve 14 weakens or reinforces the tension of the spring 9, as a result of which the size of the gap in the slotted conduit 17 changes, at the location of the ball valve 6 against the round hole 10 of the irrigation pipe 11, and therefore

5, the water flow rate of the drip varies.
