Device for watering
(57) Abstract:Use: irrigation of agricultural crops by discrete supply of water in the pockets of moisture. The inventive device for irrigation includes irrigation pipelines 1 microgyroscope 2, the cumulative capacity of 3, the siphon 6 and the mechanism of its run with the reservoir 7, the tube sensor 8 liquid level and tube-breather 9, while the siphon is made in the form of a bundle of tubes 11, and the collector 7 is supplied by a pipe 13 with the holes 14 in the walls located inside the cavity of the collector 7, while these tubes are communicated with one hand with the drain part of the siphon, and on the other, with irrigation pipelines 1. 1 Il. The invention relates to agriculture, in particular to the mechanization of irrigation, and can be used for irrigation of agricultural crops by discrete supply of water in the pockets of moisture.A device for automatic discrete irrigation, including cumulative capacity, pivotally mounted on the axis, the guide lugs, counterweight and siphon.A disadvantage of this device is the lack of reliability due to the presence of moving parts with a relatively large mA is este prototype device for irrigation, contains distribution and irrigation piping with outlets, cumulative capacity, the supply tube with a valve, siphon and the mechanism of its run with the ejector, the reservoir tube by the liquid level sensor and tube-breather.A disadvantage of this device is the complexity of its construction.The aim of the invention is to simplify the design and improve reliability.This goal is achieved by the fact that the siphon is made in the form of a bundle of tubes, the header contains tubes with holes in their walls, located inside the cavity of the collector, while the tube is in communication with one hand with the drain part of the siphon tubes, and on the other hand with irrigation pipelines.Comparative analysis of the prototype shows that the proposed device, one collector node, performs the same function as that in the prototype perform two nodes manifold and ejector. Thus, the claimed device for irrigation meets the criteria of the invention of "novelty."A comparison of the proposed system is not only the prototype, but also other technical solutions in this field of technology is not allowed to reveal in them the features distinguishing the claimed solution to the prototype, Jena schematic structural diagram of the proposed device for watering. It contains irrigation pipelines 1, micropipette 2, the cumulative capacity of 3, the supply pipe 4, valve 5, the siphon 6 and triggering the siphon, which includes the collector 7, the tube-liquid level sensor 8 and the tube-breather 9.The siphon 6 has a suction 10 and the drain 11 of the part. It can be executed wholly or partly in the form of a bundle of tubes.Through the cavity 12 of the collector 7 skipped working tube 13 with the holes 14 in the walls. The tube is connected to one side of the tube 11 and the drain side of the siphon, and on the other hand with irrigation pipelines 1. The cavity 12 of the collector 7 is communicated with the suction part 10 of the siphon 6 tube-liquid level sensor 8, and also with the atmosphere of tube-breather 9.A device for watering as follows. Water from the pipeline network through the feeding tube 4 with the required flow rate set by the valve 5, enters the holding tank 3. Upon reaching the water level in the tank 3 is connected with the sensor tube 8 to the suction side 10 of the siphon 6 water in the tube will flow into the cavity 12 of the collector 7 (tube sensor 8 runs as a siphon), forcing the air out into the atmosphere through a tube-breather 9. Then the water through the holes 14 in the walls of the working labour is the action of air in the suction part 10 of the siphon 6 is pumped into the atmosphere through the irrigation pipes and mikrovodorosli 2. Thus started the siphon 6 and the water from the storage tank 3 is fed into irrigation pipelines, and from them to the plants through mikrovodorosli 2. After emptying the tank 3, the siphon 6 is discharged. Further work cycles of accumulation of water in the tank 3 and pouring it on the irrigated area is automatically repeated.Compared to the prototype with the new essential features of the proposed technical solution is less structural assemblies, ensuring the functioning of the device, significantly reduced the number of connecting devices for distribution and irrigation pipeline network.Thus, the achieved simplifying the design and improving the reliability of the proposed device. Device for irrigation, including accumulation tank with a siphon, reported the drain part with irrigation pipelines, the charging mechanism of the siphon and the supply tube to the valve, wherein the drain portion of the siphon communicated with irrigation pipelines through manifold contains tubes with holes in the walls, placed in its cavity, while the siphon is made in the form of a bundle of tubes, the drain of each of which is in communication with the compliance
FIELD: agricultural engineering, in particular, equipment for drop irrigation of farm crops.
SUBSTANCE: apparatus has cylindrical casing with inlet and outlet openings. Cylindrical casing has threaded covers and body. Valve and elastic cuff are movably positioned inside cavity of cylindrical casing. Apparatus is further equipped with additional cuff. Main and additional cuffs are provided with orifices. Valve is made in the form of concavo-concave lens arranged in spherical belt. Valve is manufactured from material having density smaller than density of water, in particular, valve may be made from cork of 0.2-0.3 t/m3 density. Valve is arranged in casing between cuffs and is adapted for alternating contacting through cuffs with projections oppositely arranged inside casing cavity. Projections are made in the form of spherical segments, with radius of spheres of segments being smaller than radius of spheres of concavo-concave valve lens. Difference between radii of projection sphere and that of spheres of concavo-concave valve lens is equal to thickness of elastic cuffs. Channels on apexes of cover and casing projections are extending in radial direction toward inlet and outlet openings.
EFFECT: increased efficiency and enhanced reliability in operation.
