Abstract

The invention can be used for irrigation of agricultural crops, including livestock waste. The aim of the invention is to improve the uniformity of irrigation in the wind. For this, the nozzle of the apparatus is made of the lower 5 and upper 3 parts. The upper part 3 is rigidly connected to the barrel 2, and the lower part 5 is mounted on the barrel 2 pivotally rotatable in a vertical plane and connected kinematically with the sail sensor 10. Above the slots between parts 5 and 3 of the nozzles there are deflectors 9, and the side walls of the upper part are inclined. When working against the wind, the lower part 5 deflects downwards, increasing the flow rate and range of the jet. 3 hp f-ly. 4 il.

The invention relates to agriculture and can be used for irrigation of agricultural crops by sprinkling, including livestock drains.

The aim of the invention is to improve the uniformity of irrigation in the wind.

Fig. 1 shows the structure of the apparatus and the scheme of its operation when irrigating upwind; FIG. 2 is a section A-A in FIG. 1, FIG. 3 is a diagram of operation when watering according to belief; figure 4 - section bb in Fig, 3,

The sprinkler consists of a body 1, a barrel 2 on which the upper part 3 of the nozzle with inclined walls 4 and its lower part 5 are fixed, having the ability to rotate about the axis b in the vertical plane. A seal 7 is installed between the barrel 2 and the lower part 5 of the nozzle, and the seal does not overlap the upper slot 8 between the upper part 3 of the nozzle and its lower part: part 5. Above the slot 8 there are deflectors 9 о. 11 with the bottom part 5 of the nozzle,

Sprinkler apparatus works as follows. At. Worker-e. Against the wind (Figs 1 and 2) sail-sensor

11 is effective on the lower part. 5: nozzle and deflects it down. At the same time, the nozzle cross-section area increases and the deviation occurs. The downward jet of irrigation fluid increases, which increases its flight range with increased flow. A portion of the irrigation fluid passes into the slot 8 between the upper part 3 of the nozzle and its lower part 5, collides with the deflector 9, deflected forward and sideways and divided into droplets. This ensures a more even distribution of rain. on radius of watering.

When working in the wind (FIG OZ), the sail sensor 10 deflects forward, through the lever 11 it acts on the lower part 5 of the nozzle and deflects it upwards. With this, the cross-sectional area of the nozzle is reduced, and the water jet is deflected 5264

liquid upwards, which contributes to the reduction of the flight range at a reduced flow rate 5 Due to the fact that the outer side walls of the upper part of the nozzle are made inclined, the width of the slit decreases (up to complete overlap of it with sufficiently strong wind), which leads to

to reduce the flow of irrigation fluid. Thus, the drift of artificial rain by wind is compensated by a decrease in the consumption of irrigation liquid 15 and a decrease in the range of its flight, a deviation of the jet upwards.

 When clogged nozzle weighted

substances contained in the irrigation liquid (which is possible with the use of scientific research institutes for watering livestock

effluent), an increase in pressure in the apparatus will lead to the downward movement of the lower part 5 of the nozzle, t, e, to an increase in the cross-sectional area of the nozzle and

Thus, without complicating the design and increasing its metal consumption, uniformity is achieved.
