DETAILED DESCRIPTION

[0027] Figures 1-6 It is the best embodiment of the utility model, and the following will be combined with the drawings Figures 1-6 The utility model is further explained.

[0028] As Figures 1-2As shown, the agricultural and garden sprinkling device comprises a support 9, which is vertically arranged and inserted into the soil to keep vertical. An inclined support is arranged on the side of the support 9, and a support pipe 8 is arranged on the end of the inclined support, which is vertically arranged.

[0029] A water supply pipe is arranged on the side of the support 9, which comprises a water supply main pipe 10 and a water supply branch pipe 11. The water supply main pipe 10 is laid on the ground surface or embedded in the ground soil. The water supply branch pipe 11 is radially inserted into the surface of the water supply main pipe 10, and a plurality of water supply branch pipes 11 are arranged in sequence along the arrangement direction of the water supply main pipe 10. The number of the support pipes 8 on the side of the support 9 corresponds to the number of the water supply branch pipes 11, and the lower end of the support pipe 8 is inserted into the inside of the water supply branch pipe 11 to realize the butt joint with the water supply branch pipe 11.

[0030] A joint 7 is installed on the upper end of the support pipe 8, and the lower part of the joint 7 is sleeved on the outside of the upper end of the support pipe 8 to realize the butt joint with the support pipe 8. After the butt joint of the joint 7 and the support pipe 8 is in place, the joint inner cavity is formed between the top of the support pipe 8 and the upper part of the inner surface of the joint 7. The outer circle of the upper end of the support pipe 8 is in interference fit with the inner hole of the lower end of the joint 7, and there is no relative rotation between the support pipe 8 and the joint 7. A push rod 5 is arranged in the joint inner cavity. The push rod 5 comprises a push disc at the bottom and a rod body coaxially arranged on the upper surface of the push disc, and a spring 6 is sleeved on the outside of the rod body. The lower part of the spring 6 is located on the surface of the push disc, and the upper part of the spring 6 is located on the top of the joint inner cavity. The diameter of the push disc at the bottom of the push rod 5 is greater than the inner diameter of the upper end of the support pipe 8, and when the spring 6 is not subjected to external force, the push disc at the bottom of the push rod 5 is in close contact with and closes the upper end of the support pipe 8 under the elastic force of the spring 6.

[0031] The rod body of the push rod 5 vertically extends upward and extends to the inside of the upper end of the joint 7, and the outer diameter of the rod body of the push rod 5 is smaller than the inner diameter of the upper end of the joint 7, so that the rod body does not hinder the water flow of the upper end of the joint 7, and the upper end of the joint 7 simultaneously plays a guiding role for the rod body.

[0032] A nozzle support 2 is arranged on the upper part of the joint 7, which is sleeved on the outer circle of the upper part of the joint 7, and the top of the joint 7 enters the inside of the nozzle support 2. The inner hole of the lower end of the nozzle support 2 is in interference fit with the outer circle of the joint 7, and there is no relative rotation between them. A nozzle 4 is arranged in the inside of the nozzle support 2, and the bottom of the nozzle 4 is sleeved on the top of the joint 7.

[0033] Combination Figures 3-4As shown, the sprinkler 4 comprises a rotating disc 13, and a rotating shaft 12 is vertically arranged at the center of the upper surface of the rotating disc 13. A cylinder 15 is arranged at the lower part of the rotating disc 13, the inside of the cylinder 15 is a sprinkler cavity 16, the upper end of the sprinkler cavity 16 is closed by the rotating disc 13, the lower end of the cylinder 15 is sleeved on the upper end of the connector 7, and a sprinkling opening 14 is arranged on the side of the cylinder 15 and communicates with the sprinkler cavity 16. The rotating shaft 12 arranged on the upper surface of the rotating disc 13 extends upward to the upper part of the sprinkler support 2 and is sleeved into the rotating shaft hole 1 in the upper part of the sprinkler support 2.

[0034] A cutting knife 3 is arranged in the sprinkler cavity 16, and the cutting knife 3 is located at the upper end of the connector 7. Figures 5-6 As shown, the cutting knife 3 comprises four vertical blades 18 arranged vertically, and any two adjacent blades among the four vertical blades 18 are distributed at right angles. The cutting knife 3 further comprises three disc blades 17 arranged vertically, and the three disc blades 17 are arranged at equal intervals and are located at the upper, middle and lower parts of the four vertical blades 18 respectively, and the three disc blades 17 are connected and fixed with the four vertical blades 18 at the upper, middle and lower parts of the vertical blades 18 respectively. The inner ring of the cutting knife 3 is arranged outside the water outlet (upper end) at the top of the connector 7.

[0035] The specific working process and working principle are as follows:

[0036] The irrigation water is sent into through the water supply main pipe 10, and enters the corresponding support pipe 8 through each water supply branch pipe 11. When the water pressure of the irrigation water is greater than the elastic force of the spring 6, the water pressure will push the push rod 5 to move upward. At this time, the push disc at the bottom of the push rod 5 leaves the upper end of the support pipe 8, and opens the channel of the irrigation water. The irrigation water flows out through the upper end of the connector after passing through the inner cavity of the connector, and the rod body of the push rod 5 will perform a dredging operation on the upper end of the connector 7 once for each upward movement of the push rod 5, effectively avoiding the closure of the upper end of the connector 7.

[0037] After the irrigation water flows out through the water outlet at the top of the connector 7, it first enters the cutting knife 3, then enters the sprinkler 4 through the gap at the edge of the cutting knife 3, and then is sprayed out through the sprinkling opening 14 at the side of the sprinkler 4. During the process of the water flow being sprayed out through the sprinkler 4, the cutting knife 3 and the sprinkler 4 are pushed to rotate. Once the impurities such as leaves on the ground enter the sprinkler 4 through the sprinkling opening 14, especially when the sprinkler 4 is not spraying, the impurities will be cut into small pieces by the cutting knife 3 when the sprinkler 4 is working, and will be sprayed out with the irrigation water, thereby avoiding the blockage of the sprinkler 4.

[0038] The above merely describes preferred embodiments of the present application, but is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution of the present application and according to the technical essence of the present application still falls within the protection scope of the technical solution of the present application.
