The lower side of the outer wall b is connected to the lower side of the inner wall a to seal the lower side of the cylindrical space c. The irrigation device is placed on the ground or shallowly buried in the soil from the lower side. The outer surface of the upper side of the outer wall b is circumferentially processed with external threads, and the upper cover 8 is configured. The center of the upper cover 8 has a central opening corresponding to the second opening 2, which is used to set the sprinkler assembly 4. The inner wall of the upper cover 8 has internal threads that match the outer threads, and the upper cover 8 and the outer wall b are detachably connected by threads , sealing the upper side of the cylindrical space c, since the upper cover 8 is detachably connected with the outer wall b, the internal pipeline of the cylindrical space c can be cleaned and maintained by removing the upper cover 8 .

The drip irrigation assembly 5 is located lower than the sprinkler assembly 4. The outer wall b is perforated at the drip irrigation assembly 5, and the inner wall a is perforated near the first opening 1. A pipe connecting the drip irrigation assembly 5 and the first opening 1 is processed between the two holes as the second flow channel 6, and the second flow channel 6 is located in the cylindrical space c.

The specific forms of the switch assembly 7 can be various, which will be described in detail below.

An irrigation device proposed by the embodiment of the utility model integrates drip irrigation and sprinkler irrigation systems, and switches between drip irrigation and sprinkler irrigation according to different water supply pressures. The control process is simple, and the investment cost of facilities is reduced while meeting irrigation needs. and space occupation. In the prior art, the landscaping irrigation system is usually provided with an independent drip irrigation system and a sprinkler irrigation system, or only one irrigation system is provided. The disadvantages of the two irrigation systems at the same time are that the investment is high, the space is large, and the operation is difficult. The disadvantage of a single irrigation system is that it cannot meet the different irrigation needs of various plants such as flowers, grass, and trees planted in the garden. Compared with the prior art, in the irrigation device in this application document, the first flow channel and the second flow channel are arranged on the device body at the same time, and the switch assembly is arranged on the second flow channel. The switch assembly adjusts the device according to the water pressure of the first opening. In the working state, when the water pressure is low, the second flow channel is opened, and the drip irrigation component uses low-pressure water for drip irrigation. The components use high-pressure water for sprinkling irrigation, realizing the integration of drip irrigation and sprinkler irrigation systems, with less investment in equipment costs, and the switch components automatically switch between drip irrigation and sprinkling irrigation through water pressure. The control process is simple and reduces manpower consumption.

The switch assembly 7 is arranged on the second flow channel 6. The switch assembly 7 may include a sensor and an automatic water stop valve connected to the sensor. The sensor is used to detect the water injection pressure at the first opening 1, and the water stop valve is closed when the pressure is greater than a preset value. The second flow passage 6 is cut off, and the water stop valve opens the second flow passage 6 when the pressure is lower than the preset value. The switch assembly 7 in the above form can realize the switching function of drip irrigation and sprinkler irrigation, but the operation needs electricity and the cost is relatively high. Therefore, the switch assembly 7 can also be mechanically opened and closed as shown in FIGS. 3 to 6 . Specifically, the second flow channel 6 includes a cylindrical vertical flow channel 61 arranged axially along the main body of the device. The main body of the device also includes a cylindrical sliding groove 9 arranged radially through the side wall of the main body of the device. The sliding groove 9 is connected to the vertical The flow channels 61 are cross-connected, the diameter of the sliding groove 9 is greater than or equal to the diameter of the vertical flow channel 61, the outer wall b of the main body of the device is provided with an adjustment component 10 to block the opening 91 at the first end of the sliding groove, and the opening 92 at the second end of the sliding groove communicates with the first opening 1 .

The switch assembly 7 is arranged in the sliding groove 9 and includes a first elastic part 71 and a sliding part 72. The sliding part 72 is cylindrical, which blocks the sliding groove 9 and can slide along the sliding groove 9. The two ends of the first elastic part 71 are respectively Connected to the sliding part 72 and the adjustment assembly 10 . Wherein, the side wall of the sliding part 72 is circumferentially provided with an annular groove to form a groove area 73 , and the diameter of the groove area 73 is smaller than the diameter of the vertical channel 61 .

When in the drip irrigation state, as shown in Fig. 3 and Fig. 4, water is injected into the first opening 1 from the second end opening 92 of the sliding groove into the sliding groove 9, and the water pressure P is applied to the first opening 92 of the sliding member 72 close to the second end opening 92. One end, as shown by the solid arrow in Figure 3, pushes the sliding member 72 to slide towards the opening 91 of the first end. Since the first elastic member 71 is compressed, the sliding member 72 is balanced in force at the first position. The groove area 73 is located at the intersection position of the sliding groove 9 and the vertical flow channel 61, and the water injection at the first opening 1 flows between the groove area 73 and the side wall of the vertical flow channel 61, as shown by the hollow arrow in Figure 3; In the state of sprinkling irrigation, as shown in Fig. 5 and Fig. 6, the water injection pressure at the first opening 1 increases, and the water pressure P is applied to the first end of the sliding part 72 close to the second end opening 92, so that the sliding part 72 is subjected to greater pressure. The thrust continues to slide towards the first end opening 91 until the elastic force of the first elastic member 71 and the thrust of the water pressure P are balanced again, the sliding member 72 is in the second position, and the non-groove area 74 of the sliding member 72 is located between the sliding groove 9 and the At the intersection position of the vertical flow channel 61, the vertical flow channel 61 is shut off.

The structure of the above-mentioned switch assembly 7 can automatically adjust the drip irrigation and sprinkler irrigation state switching of the irrigation device according to the water injection pressure, without additional control process, and the structure is simple and not easy to be damaged.

In addition, in order to increase the diversity of drip irrigation speed and shorten the time from the non-water injection stage to the drip irrigation state, the radius of the sliding groove 9 between the sliding part 72 and the second end opening 92 is slightly reduced to form a circumferential clamping groove, so that the sliding The final position of the component 72 sliding toward the second end opening 92 is at the first position. At this time, the first elastic component 71 is compressed, and its elastic force is consistent with the thrust force of the water injection pressure on the sliding component 72 in the drip irrigation state. Any water injection pressure value of the elastic force of the elastic member 71 can simultaneously prevent the problem that the first opening 1 is blocked due to the slide of the sliding member from the second end opening 92 .

The switch assembly 7 realizes the drip irrigation and the sprinkler irrigation state switching when the water injection pressure increases to a certain value, and the water pressure at this moment is used as the switch assembly 7 to control the water pressure. Because for different crops, the required water pressure under the drip irrigation and sprinkler irrigation states is different.

If the control water pressure is small, a small thrust is required to push the sliding part 72 to the second position. At the second position, the elasticity of the first elastic member 71 is small to realize the force balance of the sliding member 72. Therefore, by rotating the adjustment assembly 10 away from the first end opening 91 of the sliding groove 9, the deformation of the first elastic member 71 is reduced, and the deformation of the first elastic member 71 is reduced. Loosening and tightening the adjustment assembly 10 makes the switch assembly 7 control the water pressure adjustable.

Specifically, the control water pressure can be set to 0.2MPa, 0.25MPa, 0.30Mpa, etc. Taking the control water pressure as 0.25MPa as an example, when the water pressure is lower than 0.25MPa, the sliding part 72 is at the first position, and the groove area 73 is located at the sliding position. The groove 9 intersects with the vertical channel 61, and the irrigation device is in the drip irrigation state; when the water pressure is higher than 0.25MPa, the sliding part 72 slides to the second position, and the non-groove area 74 of the sliding part 72 is located between the sliding groove 9 and the vertical At the intersection position of the flow channel 61, the vertical flow channel 61 is closed, and the irrigation device is in the sprinkler state; when the water pressure is lower than 0.25MPa again, the first elastic member 71 pushes the sliding member 72 back to the first position, realizing drip irrigation according to the pressure , Sprinkler irrigation state switching. The first elastic member 71 can be a spring.

Further, a first sealing ring 75 is provided on the side wall of the non-groove area 74 of the sliding part 72, and the first sealing ring 75 prevents water injection from flowing into the vertical channel 61 or the first elastic part 71 from the second end opening 92. , play a role in preventing water leakage of the device and corrosion of the first elastic member 71, and at the same time prevent water injection sediment from entering between the sliding member 72 and the sliding groove 9, so as to ensure smooth sliding of the sliding member 72.

One end of the straight channel 61 and the other end of the vertical channel 61 communicate with the first opening 1 . The serpentine coiled flow channel 62 makes the water flow toss and turn, which can dissipate the energy of the water injection, reduce the pressure of the water flow at the drip hole of the drip irrigation assembly 5, and make the water flow slowly drip out from the drip hole of the drip irrigation assembly 5.

As shown in FIG. 7 , the drip irrigation assembly 5 is specifically in a cylindrical shape, and the inner wall forms a drip hole 51 , on which is provided an air hole 52 penetrating through the side wall, and the air hole 52 is used to prevent sand from being sucked back. When the drip irrigation process stops, the water flows back from the drip hole 51 to the serpentine flow channel 62, and the drop hole 51 will produce an instant decompression. By increasing the air hole 52, the air in the drip hole 51 will flow into the drip hole 51 through the air hole 52 during the backflow process. , to prevent the inhalation of air from the drop hole 51 to cause the sediment near the drop hole 51 to enter the drop hole 51 and the serpentine coiled flow channel 62.
