Abstract

FIELD: agricultural engineering, in particular, farm crop irrigation equipment.

SUBSTANCE: irrigation apparatus has two accumulators, each equipped with winding mechanism and drum. Diameter of outlet aperture is equal to inner diameter of flexible pipeline, which is free from dead part. In operating position, end part of flexible pipeline is put onto outlet opening of second accumulator. After delivering half the irrigation norm through first accumulator, water is supplied through second accumulator. This is necessary in order to equalize irrigation norms through first and last valves lengthwise of flexible pipeline.

EFFECT: wider operational capabilities and increased efficiency of irrigation apparatus.

Description

The invention relates to agriculture, in particular to irrigation of crops.

A device for irrigation along the furrows containing a flexible pipe connected to the pump unit and having adjustable nozzles (see the manual on the mechanization of irrigation - M .: Kolos, 1979-304 p.). For work, unwrap the flexible pipe folded over the tape across the field, connect it to the pump unit and water it through adjustable nozzles into each irrigation furrow. At the end of irrigation, the pipeline is disconnected from the pump unit and wound on a drum.

The disadvantage of this method is the presence of idle passes of the unit across the field when unwinding and unwinding the pipeline, difficulties in regulating the irrigation rate along the length of the pipeline.

Closest to the claimed proposal is a technical solution comprising a power plant equipped with a drive with a flexible irrigation pipe having water outlets and a folding mechanism, where the drive at the outlet has an oil seal with a slot-like exit hole with a width equal to the width of a folded flexible irrigation pipe made with variable diameters varying in proportion to the change in piezometric pressure along the length of the pipeline, and in the form of a sleeve having the ability to twist water outlets, and additional outlets, moreover, outlets are equipped with latching flap valves located on the outer and inner surfaces of the pipeline with different distances between them, while outlets with a shorter distance between them are designed for irrigation along ordinary furrows, and with a greater distance for irrigation along sparse furrows - crevices (A.S. No. 2221415, Cl. A 01 G 25/02, 2004).

The technical solution to the problem is to increase irrigation efficiency and expand operational capabilities.

This object is achieved in that in a device for irrigation of crops, including a power plant with a drive, having a flexible irrigation pipe with outlets and a folding mechanism in the form of a coil, characterized in that the power plant is equipped with additional drives with one flexible irrigation pipe of constant diameter, switchable from one drive to another by means of a clamp, knot and ring, while the diameter of the flexible pipe, as well as the diameters of the outlet th throughout the length are constant.

According to the patent and scientific literature, the claimed combination of features is unknown, aimed at achieving the goal, which allows us to conclude that the claimed features are material.

The novelty of the proposed proposal is due to the fact that the water supply to the flexible pipe of constant diameter is carried out from two drives for uniform supply of water to the furrows from the holes with a large length of flexible irrigation pipe.

The invention is illustrated by drawings, in which Fig. 1 shows a general view of the device from the side when connecting the sleeve to one of the drives, Fig. 2 shows a general view of the device from the side when connecting the sleeve to two drives, in Fig. 3 is a top view, in Fig. 4, 5 - end part of the pipeline.

The difference in the water supply through one valve - the hole along the length of the pipeline can be reduced by increasing the diameter of the flexible pipe without changing its length. If it is necessary to increase the length of the pipeline in order to provide a larger area of the installation, an increase in the diameter of the flexible irrigation pipeline is required in proportion to its length, which is not economically viable.

A device for irrigation of crops contains a power plant, which is a drive consisting of: a drum 1 of a certain diameter with a coil 2 for winding a flexible pipe 3 of reclamation fabric located on the shaft passing through the center of the drum. The water supply is carried out through the inlet pipe 4 having a valve for regulating the water supply and a water meter. At the bottom of the drum there is an exhaust pipe 5, with a diameter equal to the diameter of the flexible pipe, with a pressure gauge 7 for determining the pressure of water in the pipe. On the outlet pipe (5) one end of the flexible pipe is put on in the turned position, the other end of the pipe is attached to the cable 7, the cable length is equal to the length of the sleeve wound on the reel (Figs. 1, 2, 3). With the full layout of the pipeline 3, a cable 7 is located inside, performing a reverse winding of the sleeve onto the reel 2 into the drum 1.

The design of the end part of the pipeline is shown in Figs. 4, 5. The reverse winding cable is not attached to the plugged part of the sleeve, but passes through it. At the exit, it is equipped with a ring 8 and at a distance of one meter from it with a node 9. The flexible pipe at point “A” is pinched with a clamp 10 so that the node 9 on the cable is located closer to the end part. When the cable moves for reverse winding, the collar 10 will not allow node 9 to pass at point “A” and the flexible pipe will begin to fold into a drum (Fig. 5).

The essence of the design of this node is as follows:

During the operation of the installation, after the water is supplied to the nozzle 4, the water will enter the drum 1, then from the drum to the outlet 5. As the pressure in the drum increases, the water will move sleeve 3, the coil 2 will begin to rotate, and the flexible pipe will unfold “ of himself. ” After the sleeve 3 is laid out in full length, a second, similar drive, but without a flexible pipe, is installed to its end part (Fig. 1, 2). The ring 8 from the cable 7 of the first drive is attached to the coil 2 'of the second drive. The sleeve 3 is put on the outlet 5 ', the collar 10 is removed at point “A”, and water from the pipeline 3 fills the drum of the second installation. After half the irrigation rate is issued to the site, the water supply to the first drive is stopped, and at the same time, water is supplied to the second one at the same rate. The remaining half of the irrigation rate will be fed through the second drive. This is necessary in order to equalize the amount of water supplied through the first and last valves, and vice versa.

Upon completion of irrigation, the water supply to the second drive is stopped. The clamp 10 compresses the flexible pipe at point “A”, the end of the sleeve is removed from the outlet of the second installation, the ring 8 is disconnected from the coil 2 'and the pipe is rolled into the first drive by rotation of the handle 11.

If the design of the sleeve and the cable (Figs. 4, 5) is performed at each drive, then the sleeve can be folded into any of the drives.
