[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 5As shown, a novel drip irrigation belt is inlaid with an anti-clogging dripper, including a dripper 1, a water inlet part 2, a water outlet part 3, a water inlet trough 4, a diverter column 5, a spacer bar 6, a spacer belt 7, a water inlet channel 8, a water inlet hole 9, a water outlet block 10, a longitudinal rack 11, a water collecting chamber 12, a transverse rack 13, a flow control block 14, a flow control block 2 15, a water outlet channel 16, a slot 17, a notch 18, a connecting rod 19, a guide block 20, a top rod opening 21, a reinforcing rib 22, and a glue injection port 23.

[0022] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 5 As shown, the material of the dripper 1 is PVC. The dripper 1 includes an integrally formed and connected water inlet part 2 and a water outlet part 3. The water inlet part 2 includes an inlet trough 4, a diverter column 5, a spacer bar 6, a spacer belt 7 and a production molding mechanism. A plurality of diverter columns 5 and spacer bars 6 are arranged side by side and evenly spaced in the water inlet trough 4. The diverter column 5 is located above every two spacer bars 6, which can not only divert the water flow and guide the water flow into the water inlet hole 9, but also block large-volume impurities and have the function of filtering impurities.

[0025] A partition strip 7 is provided on one side of the spacer strip 6, and a water inlet channel 8 is formed between the diverter column 5, the spacer strip 6, the partition strip 7 and the water inlet groove 4; a production molding mechanism is provided on the water inlet groove 4;

[0026] The spacer bar 6 is arranged obliquely. Specifically, the upper end surface of the spacer bar 6 is "S"-shaped. The height of the upper end of the spacer bar 6 is higher than the diverter column 5, and the height of the lower end is lower than the diverter column 5; the height of the upper end of the spacer bar 6 is flush with the height of the water inlet trough 4.

[0027] The lower end of the spacer bar 6 is provided with a hollow area, which is connected to form a water inlet 9. Through the setting of the hollow area, the water flow in the drip irrigation belt can enter the water outlet 3 from multiple directions. The hollow area and the diversion column 5 cooperate to play a role of multi-directional filtering and self-cleaning.

[0028] The water outlet part 3 includes a water outlet block 10, a longitudinal rack 11, a water collecting chamber 12, a transverse rack 13, a flow control block 14 and a flow control block 2 15. The water outlet block 10 is provided with longitudinal racks 11 with relatively staggered intervals. One end of the longitudinal rack 11 is connected to the water collecting chamber 12. The bottom of the water collecting chamber 12 is inclined from the opening to the outside to form a slope to prevent water from accumulating at the opening of the water collecting chamber 12, thereby providing continuous power for the flow of water.

[0029] A transverse rack 13 is provided at the other end of the longitudinal rack 11, and two flow control blocks 14 facing opposite directions are provided between the relatively arranged longitudinal racks 11. One end of the two flow control blocks 14 is connected to the flow control block 2 15, and the flow control block 2 15 is meshed with the transverse rack 13 at intervals; a gap 18 is left between the other end of one of the flow control blocks 14 and the water collecting chamber 12 for connecting the water inlet hole 9; the other end of the other flow control block 14 is against the outside of the water collecting chamber 12.

[0030] A water outlet channel 16 is formed between the longitudinal rack 11 , the transverse rack 13 , the flow control block 1 14 and the flow control block 2 15 . One end of the water outlet channel 16 is connected to the water inlet hole 9 , and the other end is connected to the opening of the water collecting chamber 12 .

[0031] The width of the water inlet groove 4 is 2 / 3 to 3 / 4 of the width of the water outlet block 10. One side of the water inlet groove 4 is flush with the water outlet block 10, and a clamping groove 17 is formed between the other side of the water inlet groove 4 and the back side of the water outlet block 10. The clamping groove 17 allows the dripper 1 to be accurately clamped on the transport track of the drip irrigation tape production device to ensure that the drippers 1 in the produced drip irrigation tape are all in the same direction.

[0032] When any part between two adjacent spacer bars 6 is blocked by small particles of impurities, water can flow into the water outlet 3 from other directions. The continuous flow of water will cause pressure in multiple directions on the blocked section, and the small particles of impurities blocked on the spacer bars 6 will be washed away. The impurities can re-enter the drip irrigation belt and flow forward with the water flow, or enter the water outlet 3 of the dripper 1 through the water inlet hole 9. The small particles of impurities in the outlet flow channel 16 flow into the water collecting chamber 12 along the direction of the water flow and flow out from the outlet 26 on the drip irrigation belt.

[0033] The flow control block 14 includes a connecting rod 19 and a guide block 20. A plurality of guide blocks 20 are evenly arranged on the connecting rod 19. The outer ends of the guide blocks 20 are arc-shaped. The length of the guide blocks 20 is 1 mm. The spacing between adjacent guide blocks 20 is 2 mm. The angle between the guide blocks 20 and the connecting rod 19 is 85°. The tooth spacing of the longitudinal rack 11 is 2 mm, the tooth length is 1 mm, and the angle formed between the longitudinal rack 11 and the water outlet block 10 is 85°. As shown in the figure, in this embodiment, the inclination of the guide block 20 and the longitudinal rack 11 is opposite to the direction of the water flow, so that in the process of the water flow flowing forward, a water flow vortex will be formed between the angles of the inclination of the guide block 20 and the longitudinal rack 11, which increases the resistance of the water flow forward and reduces the water flow speed in the water outlet channel 16, so that the overall water output of the dripper 1 is smooth and uniform. Furthermore, the gap between the guide block 20 and the longitudinal rack 11 is smaller than their own width, so that the water outlet channel 16 becomes narrower and the channel volume becomes smaller, making the subsequent water outlet smoother.

[0034] The production and molding mechanism includes a push rod opening 21, a reinforcing rib 22 and a glue injection port 23. Hollow cylindrical push rod openings 21 are respectively provided on both sides of the water inlet groove 4. One of the push rod openings 21 is provided on the back side of the water collecting chamber 12 and is connected to the partition belt 7 through a reinforcing rib 22. During the production process, after the dripper 1 is injection molded and cooled, the push rod of the injection molding machine pushes the dripper 1 out of the mold through the push rod opening 21.

[0035] A glue injection port 23 is provided in the middle of the inner side of the water inlet groove 4, so that the glue material can be filled evenly on both sides during the glue injection process.

[0036] The width of the water outlet block 10 is 5.7 mm, the length of the water outlet block 10 and the length of the water inlet groove 4 are both 18.6 mm; the sum of the heights of the water outlet block 10 and the water inlet groove 4 is 2 mm. The volume of the dripper 1 is reduced compared to the volume of the dripper in the prior art, thereby reducing the use of related production materials and reducing production costs.

[0037] It should be explained that in actual use, the dripper 1 needs to be used in conjunction with a drip irrigation belt. The drip irrigation belt is used in farmland irrigation with special accessories for connection, such as adapters, valves, lock nuts, etc. The drip irrigation belt can be connected to a water pipe for drip irrigation.

[0038] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
