Vortex nozzles 15 are distributed on the outer surface of the drain pipe 35 at equal intervals, the inclination angle of the vortex nozzle 15 is the same as that of the mounting rod 16, the inner wall of the vortex nozzle 15 is connected with a fixed seat 36 in a clamping manner, the middle end of the fixed seat 36 is movably connected with a movable shaft 37, turbine blades 38 are arranged on the outer surface of the movable shaft 37, and the interior of the vortex nozzle 15 is of a hollow structure; the outside of drain pipe 35 sets up a plurality of vortex shower nozzles 15, can increase to planting in the planting groove 17 and being watered the area to the inside turbine blade 38 that sets up of vortex shower nozzle 15 is high-speed rotatory under hydraulic drive, makes inside moisture water go out with the arc form watering, when improving watering effect, can also stabilize inside water pressure, thereby has increased holistic practicality.

The working principle is as follows: when the planting layer structure for ecological restoration of the garden slope capable of collecting rainwater is used, firstly, the planting groove 17 is dug in the soil layer 3 of the slope 1, vegetation is planted in the planting groove 17, then the shunt tubes 14, the drain tubes 35 and the planting groove 17 are arranged in rows, one ends of the shunt tubes 14 are connected with the water delivery tubes 34, the water delivery tubes 34 are connected with the water pumps 33, in the rainy weather, the impeller 12 rotates clockwise under the influence of wind, the impeller 12 is matched with the external water storage plate 13 to collect the rainwater, the impeller 12 is in a rotating state by utilizing the gravity generated by the wind and the water, the impeller 12 drives the rotating shaft 10 through the fixed sleeve 11, the rotating shaft 10 drives the scroll 30 to rotate, the dustproof fiber cloth 20 on the outer surface of the scroll 30 is recycled inwards, the dustproof fiber cloth 20 is matched with the clamping slide block 27 to slide along the guide rail 28, so that the gap at the upper end of the water collecting tank 2 is opened, and in the sliding process, the clamping slide block 27 is contacted with the contact sensor 8, the contact sensor 8 starts the motor 5 through a signal wire 9, the motor 5 rotates the transmission chain 6, the transmission chain 6 is transmitted with the mixing shaft 7, the mixing shaft 7 is in a rotating state, in the process of filling rainwater into the water collecting tank 2, harmful substances such as sundries, dust and the like contained in the rainwater are filtered by the filter grids 24, the activated carbon filter screen 25 and the PP cotton filter screen 26 in a grading way, the mixing shaft 7 drives the helical blade 19 and the stirring rod 18 to rotate, the materials in the fertilizer box 21 are conveyed into the water collecting tank 2 by the pressure generated by rotation, the helical blade 19 preliminarily crushes the materials, small particles of the materials are discharged from the through cavity 23, the blocky materials are dispersed by the stirring rod 18, the fertilizer and the rainwater are mixed, the nutrients for watering the rainwater are increased, when the weather of the rainwater is over, the clamping slide block 27 is pulled to enable the dustproof fiber cloth 20 to cover the upper end of the water collecting tank 2, avoid the inside moisture evaporation of catch basin 2, when needs are watered to the vegetation, start water pump 33 says that the rainwater suction of the inside collection of catch basin 2 to raceway 34, shunt tubes 14 is carried water by raceway 34 again, shunt tubes 14 is to the corresponding drain pipe 35 in with the moisture reposition of redundant personnel, join in marriage out from vortex shower nozzle 15 again, at the in-process of watering, it is rotatory to drive turbine blade 38 by the inside loose axle 37 of fixing base 36, turbine blade 38 is by water pressure drive, make the water arc form spray away, and can balance the inside water pressure of raceway 34, make a plurality of vortex shower nozzles 15 water yield the same, thereby whole practicality has been increased.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
