In order to adjust the spraying range better, an adjusting nut is arranged at the outlet of the spray head 4, and the outlet diameter of the spray head 4 can be adjusted by rotating the nut.

In order to avoid the overlarge swing range of the swing rod, the upper end surface of the shell 2 is provided with a mounting groove, the middle part of the swing rod is fixed in the mounting groove through a pin shaft, and the width of the mounting groove can limit the swing range of the swing rod.

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: a guide rod 603 in the change-over switch 6 is controlled by a swing rod 607 at the upper end and a wedge-shaped block 609 at the lower end of the swing rod 607; referring to fig. 2 and fig. 6, when the upper end of the swing lever 607 swings forward, the concave portion of the wedge 609 corresponds to the upper end of the guide 603, i.e. the guide 603 is at the top of its stroke, and referring to fig. 4, the upper and lower channels 602 in the switch 6 are in an open state, and the upper channel 602 is in an open state; that is, the water flows from the passage 602 above the switch 6 to the upper layer of the power box 7, and the rotary 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 shaft, and after the positioning rod 606 rotates to be in contact with the swinging rod 607, the positioning rod 606 stirs the upper end of the swinging rod 607, so that the upper end of the swinging rod 607 swings backwards; at this time, the protrusion of the wedge 609 corresponds to the upper end of the guide rod 603, and the guide rod 603 moves upward, so that the channel 602 at the lower part of the switch 6 is opened and the channel at the upper part is closed; the water flow enters from the lower part of the power box 7 and drives the rotating shaft 3 to rotate anticlockwise. After the rotating shaft 3 rotates anticlockwise, the positioning rod 606 also rotates anticlockwise until the positioning rod 606 reversely pushes the swing rod 607 again; then state one is restored.

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 swing rod 607, and then the swing rod 607 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 principle, when only one positioning rod 606 is provided, the rotating shaft of the spray head 4 rotates reversely for 360 degrees; when there are two positioning rods 606, the angle between the two positioning rods 606 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, a vertical rod 5, an eccentric wheel 12 for driving the vertical rod 5, an end face gear 15, a pinion 16 and the like are designed, and the function of the part is mainly to realize the adjustment of the angle of the spray head 4; the principle is as follows:

when the rotating shaft 3 rotates, the cross bar 10 on the rotating shaft 3 drives the sleeve 11, the eccentric wheel 12 and the pinion 16 to revolve together with the rotating shaft 3, and the pinion 16 is meshed with the face gear 15, so that the pinion 16 rotates and drives the eccentric wheel 12 to rotate while revolving; after the eccentric wheel 12 rotates, the vertical rod 5 is extruded, so that the vertical rod 5 moves up and down; the spraying angle of the spray head 4 is reduced, the range of the spray head 4 is changed, and the close-range grass and trees are irrigated; through the change of the elevation angle of the spray head 4 in the rotating process, the water flow can revolve around and walk along an S-shaped route, and the vegetation in the range can be sprayed in an all-round manner.

Because a one-way clutch is arranged between the eccentric wheel 12 and the sleeve 11, the sleeve 11 can only drive the eccentric wheel 12 to rotate in one direction; in this way, when the sleeve 11 rotates in the reverse direction, the eccentric 12 is subjected to the pressing force of the stem 5, and a quick return or a holding is effected. The eccentric wheel 12 can be rotated again until the sleeve 11 rotates forwards again, so that more randomness is increased, and the repeated track of the spray head 4 can be avoided; more comprehensive spraying is realized.

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.

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.
