When the invention is used, firstly, the height of the supporting leg 1 is adjusted, then the water inlet pipe 8 is connected to a water source, and a water source switch is turned on; then the water flow can travel by firstly flowing into the two channels 602 of the switch 6 through the tee joint and being controlled by the switch 6, so that the water flow flows out of one channel 602 and flows into the upper layer or the lower layer of the power box 7, and then flows into the spray head 4 from the water outlet pipe 9 for spraying.

The power box 7 in the device mainly has the function of controlling the rotating shaft 3 to rotate forwards or backwards; the working principle is as follows.

Through the control of the change-over switch 6, the water flow can enter the upper layer or the lower layer of the power box 7, because there are two impellers 703 on the rotating shaft 3, and the two impellers 703 have different rotation directions; therefore, when water flows from the upper layer or the lower layer, the rotation direction of the rotating shaft 3 is opposite; hereinafter, the description will be given by taking an example in which the rotation shaft 3 rotates clockwise when water flows through the upper layer, and the rotation shaft 3 rotates counterclockwise when water flows through the lower layer.

The change-over switch 6 in the device mainly plays a role in controlling the circulation path of water flow in the power box 7 and then indirectly controlling the rotation direction of the rotating shaft 3, and the working principle is as follows.

The first state: the valve core 603 in the change-over switch 6 is controlled by a vertical rod 607, a shift lever 609 and a positioning rod 606; referring to fig. 2, 3 and 6, when the shift lever 609 on the vertical rod 607 is at the left position in fig. 3, the valve core 603 is at the left position in fig. 4, at this time, water can flow out from the rear water outlet of the valve core 603 through the switch 6, and then flows into the upper layer of the power box 7, at this time, the water can push the impeller 703, so that the rotating shaft 3 rotates clockwise.

And a second state: with the clockwise rotation of the rotating shaft 3, the rotating disc 604 on the rotating shaft 3 also rotates clockwise, so that the positioning rod 606 on the rotating disc 604 rotates along with the rotating disc, and after the positioning rod 606 rotates to be in contact with the shift lever 609, the shift lever 609 is shifted by the positioning rod 606, so that the shift lever 609 drives the vertical rod 607 to rotate counterclockwise; referring to fig. 3, the state of the shift lever 609 is changed from left to right; meanwhile, the valve core 603 also rotates counterclockwise, so that the through flow in the valve core 603 changes, and at the moment, water flow can flow into the lower chamber 701 of the power box 7 from the water outlet on the front side of the valve body 601 to drive the rotating shaft 3 to rotate counterclockwise. After the rotating shaft 3 rotates anticlockwise, the positioning rod 606 also rotates anticlockwise until the positioning rod 606 reversely pushes the shift lever 609 again; then state one is restored.

Since the valve core 603 is rotating, the water flow in the valve body 601 is in a closed state, in order to avoid dead points, during the rotation of the valve core 603, the water in the elastic water bag 12 will continue to push the rotation to go over the dead points.

In summary, by the cooperation of the switch 6 and the power box 7, it can be known that the rotating shaft 3 is driven to rotate by the power of the water flow, and then the nozzle 4 can be rotated back and forth; the reciprocating rotation of the nozzle 4 is realized by rotating a certain angle through the positioning rod 606 on the turntable 604 and matching with the shift lever 609, and then the shift lever 609 is pushed to rotate reversely, and the operation is repeated and circulated in sequence. Because the turntable 604 is provided with a plurality of positioning grooves 605 which are uniformly distributed; according to the above principle, when there is only one positioning rod 606, the nozzle 4 rotates in reverse every 360 degrees (approximately); when there are two positioning rods 606, the angle between the two positioning rods 606 (the side including the shift lever 609) is the angle of each rotation of the nozzle 4. Through cartridge locating lever 606, can make things convenient for quick control shower nozzle 4's rotation range, the effect is directly perceived simultaneously, and is simple quick. Moreover, the spray head 4 rotates in a reciprocating manner, so that the water inlet pipe 8 and the book outlet pipe are not wound, and the spray head 4 is connected without a rotary joint; the problem of water leakage is avoided.

In the device, an active cylinder 10 and a passive cylinder 5 are designed, and the functions of the active cylinder and the passive cylinder are mainly used for adjusting the angle of the spray head 4; the principle is as follows:

when the rotating shaft 3 rotates, the convex block 11 on the rotating shaft 3 can extrude the piston rod in the driving cylinder 10, so that the gas in the driving cylinder 10 is pressed into the driven cylinder 5; then the piston rod of the driven cylinder 5 is jacked up to move upwards; thereby the right end of the nozzle 4 is upward; the spraying angle of the spray head 4 is reduced, the range of the spray head 4 is shortened, and the close-distance grass and trees are irrigated.

When the plug rod of the passive cylinder 5 rises to a certain height, the rope 504 in the passive cylinder 5 is tensioned, the supporting rod 503 at the bottom of the passive cylinder 5 is pulled, the supporting rod 503 extrudes the valve rod of the pressure valve 502, the pressure valve 502 is deflated, the piston rod in the passive cylinder 5 is reset downwards under the action of the tension spring 501, and the angle of the spray head 4 is restored to the original position; when the piston rod in the passive cylinder 5 returns to the bottom, the push rod 505 at the bottom of the piston will press the rod 503, so that the rod 503 is not pressing the pressure valve 502, and the pressure valve 502 is closed again. The passive cylinder 5 can therefore be recharged, effecting a further progressive lowering of the spray head 4.

The design of this part has utilized the rotation of pivot 3, has realized the automatic slow regulation of angle of shower nozzle 4, through the regulation of 4 every single move angles of shower nozzle, makes the vegetation in the whole spray regime all can obtain concentrated irrigation, has avoided traditional shower nozzle 4, and only the distal end is irrigated abundant problem. When the two positioning rods 606 are placed, the protrusion 11 and the lever 609 on the rotating shaft 3 should be placed on the same side of the two positioning rods 606.

The device can carry out various operations which cannot be carried out by the traditional spray head 4 by utilizing the spray range and the adjustability of the spray angle; for example, when a circular or fan-shaped flower bed is irrigated, the device is placed in the middle position, so that uniform spraying irrigation without dead angles can be realized, rain and dew on flowers and plants are uniformly stained, the growth vigor is consistent, and the shape is attractive. Meanwhile, aiming at the bar shape, the device can be placed at one end, the spraying range is adjusted, and uniform spraying in the bar-shaped area is realized.
