[0001] This utility model relates to the field of drip irrigation pipe technology, and in particular to a cleaning device for anti-clogging drip irrigation nozzles. Background Technology

[0002] Drip irrigation pipes are important irrigation devices in drip irrigation systems. They deliver water and nutrients needed by crops drop by drop, evenly and slowly, into the soil around the crop roots through a low-pressure pipeline system and sprinklers installed on the capillary tubes, according to the crop's water requirements.

[0003] In the existing technology, the following problems exist: it lacks a metering and dispensing structure, has poor functionality, is inconvenient for automatic and uniform mixing, and is difficult to clean inside the liquid tank. To address these issues, application number 202221796566.6 discloses a drip irrigation device for tobacco planting, including a base and a liquid tank. The liquid tank is fixedly connected to the top of the base, and fixed casters are movably connected to the four corners of the bottom of the base.

A hose is fixedly connected to the output end of the water pump, and a water delivery pipe is fixedly connected to the tail end of the hose. Drip irrigation ports are evenly arranged at the bottom end of the water delivery pipe.

[0004] The above-mentioned patent has the following problems when in use: When in use, the water dripping from the drip irrigation nozzle will cause soil to splash upwards after contacting the soil. After a long period of use, the soil splashed upwards will block the drip irrigation nozzle. The device does not have an anti-clogging structure and cannot perform anti-clogging operation on several drip irrigation nozzles, thus affecting the normal use of the entire device.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging drip irrigation nozzle cleaning device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A clog-resistant drip irrigation nozzle cleaning device includes a drip irrigation nozzle, a connecting pipe, and an anti-clogging mechanism;

[0009] One end of the drip irrigation nozzle is sealed to a connecting pipe, the connecting pipe is equipped with a one-way valve, and the drip irrigation nozzle is equipped with an anti-clogging mechanism, which is connected to the connecting pipe.

[0010] The anti-clogging mechanism includes a filter plate, a conical rod, a transmission rod, a circular plate, needle rods, a delivery groove, a spring, and a sealing ring. A filter plate is fixedly installed at one end of the drip irrigation nozzle, and the filter plate has multiple filter holes. A circular plate is slidably connected inside the drip irrigation nozzle, and multiple needle rods are fixedly connected to one side of the circular plate. One end of each needle rod corresponds to one of the filter holes. Liquid is delivered between the one-way valve and the conical rod through the connecting pipe, causing the pressure between them to gradually increase. Under this pressure, the conical rod slides a certain distance inside the drip irrigation nozzle, and through the transmission rod and the circular plate, one end of each needle rod inserts into the filter hole, thereby removing impurities clogging the filter hole.

[0011] Preferably, a tapered rod is slidably connected inside the drip irrigation nozzle, one end of the tapered rod is fixedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to the circular plate. The tapered rod drives the circular plate to slide synchronously inside the drip irrigation nozzle through the transmission rod, thereby compressing the spring.

[0012] Preferably, the drip irrigation nozzle has a delivery groove, one end of which corresponds to the conical rod, and the other end of which is located between the circular plate and the filter plate, for delivering liquid and achieving the effect of pressure relief.

[0013] Preferably, a spring is fixedly sleeved on the transmission rod, and one end of the spring is fixedly connected to the drip irrigation nozzle. The elastic potential energy of the spring causes the tapered rod, transmission rod, circular plate, and multiple needle rods to return to their original shape.

[0014] Preferably, a sealing ring is fixedly installed inside the drip irrigation nozzle. The sealing ring abuts against one end of the conical rod. The sealing ring is adapted to one end of the conical rod. The diameter of the plurality of needle rods is smaller than the diameter of the plurality of filter holes to avoid clogging of the plurality of filter holes.

[0015] Preferably, a sealing gasket is fixedly installed at one end of the tapered rod, the sealing gasket is in contact with the sealing ring, a groove is provided on the tapered rod, a sealing ring is fixedly installed in the groove, and the sealing ring is slidably connected to the drip irrigation nozzle to improve the sealing performance.

[0016] Preferably, a second sealing ring is fixedly sleeved on the circular plate, and the second sealing ring is slidably connected to the drip irrigation nozzle. The plurality of filter holes and needle rods are arranged at equal intervals on the filter plate and the circular plate, so that the plurality of needle rods can be inserted into the plurality of filter holes respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The present invention provides a cleaning device for an anti-clogging drip irrigation nozzle. The connecting pipe delivers liquid to the space between the one-way valve and the conical rod, thereby gradually increasing the pressure between them. Under the pressure, the conical rod slides a certain distance inside the drip irrigation nozzle. Through the transmission rod and the circular plate, one end of each of the needle rods is inserted into the filter hole, thereby removing impurities that are clogging the filter hole. After that, the liquid delivery to the connecting pipe is stopped. As the liquid is discharged through the connecting groove, the pressure between the one-way valve and the conical rod decreases. At the same time, the spring force causes the conical rod, the transmission rod, the circular plate, and the multiple needle rods to return to their original positions. After repeating the above operation for a period of time, the filter plate 4 is protected from clogging. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a device for cleaning drip irrigation nozzles to prevent clogging. (Refer to...) Figure 1-4 A clog-resistant drip irrigation nozzle cleaning device includes a drip irrigation nozzle 1, a connecting pipe 2, and an anti-clogging mechanism;

[0027] One end of the drip irrigation nozzle 1 is sealed to a connecting pipe 2, and a one-way valve 3 is provided on the connecting pipe 2. The drip irrigation nozzle 1 is equipped with an anti-clogging mechanism, which is connected to the connecting pipe 2.

[0028] The anti-clogging mechanism includes a filter plate 4, a conical rod 6, a transmission rod 7, a circular plate 8, needle rods 9, a delivery groove 10, a spring 11, and a sealing ring 12. A filter plate 4 is fixedly installed at one end of the drip irrigation nozzle 1. The filter plate 4 has multiple filter holes 5. A circular plate 8 is slidably connected inside the drip irrigation nozzle 1. Multiple needle rods 9 are fixedly connected to one side of the circular plate 8. One end of each needle rod 9 corresponds to one of the multiple filter holes 5. The liquid is delivered to the one-way valve 3 and the conical rod 6 through the connecting pipe 2, thereby gradually increasing the pressure between them. At this time, under the action of the pressure, the conical rod 6 slides a certain distance inside the drip irrigation nozzle 1. Through the transmission rod 7 and the circular plate 8, one end of each needle rod 9 is inserted into the filter hole 5, thereby achieving the effect of removing impurities that are clogging the filter hole 5.

[0029] In this embodiment, a tapered rod 6 is slidably connected inside the drip irrigation nozzle 1. A transmission rod 7 is fixedly connected to one end of the tapered rod 6. One end of the transmission rod 7 is fixedly connected to the circular plate 8. The tapered rod 6 drives the circular plate 8 to slide synchronously inside the drip irrigation nozzle 1 through the transmission rod 7, thereby compressing the spring 11.

[0030] In this embodiment, the drip irrigation nozzle 1 is provided with a delivery groove 10. One end of the delivery groove 10 corresponds to the conical rod 6, and the other end of the delivery groove 10 is located between the circular plate 8 and the filter plate 4. It is used to deliver liquid and achieve the effect of pressure relief.

[0031] In this embodiment, a spring 11 is fixedly sleeved on the transmission rod 7. One end of the spring 11 is fixedly connected to the drip irrigation nozzle 1. The elastic potential energy of the spring 11 causes the tapered rod 6, the transmission rod 7, the circular plate 8, and the multiple needle rods 9 to return to their original state.

[0032] In this embodiment, a sealing ring 12 is fixedly installed inside the drip irrigation nozzle 1. The sealing ring 12 abuts against one end of the tapered rod 6. The sealing ring 12 is adapted to one end of the tapered rod 6. The diameter of the multiple needle rods 9 is smaller than the diameter of the multiple filter holes 5 to avoid clogging of the multiple filter holes 5.

[0033] In this embodiment, a sealing gasket 13 is fixedly installed at one end of the tapered rod 6. The sealing gasket 13 is in contact with the sealing ring 12. A groove is provided on the tapered rod 6. A sealing ring 14 is fixedly installed in the groove. The sealing ring 14 is slidably connected to the drip irrigation nozzle 1 to improve the sealing performance.

[0034] In this embodiment, a sealing ring 2 is fixedly sleeved on the circular plate 8. The sealing ring 2 is slidably connected to the drip irrigation nozzle 1. Multiple filter holes 5 and needle rods 9 are arranged at equal intervals on the filter plate 4 and the circular plate 8, so that multiple needle rods 9 can be inserted into multiple filter holes 5 respectively.

[0035] Working principle: During use, the liquid is transported to the one-way valve 3 and the conical rod 6 through the connecting pipe 2, thereby gradually increasing the pressure between them. At this time, under the action of pressure, the conical rod 6 slides a certain distance inside the drip irrigation nozzle 1, and the conical rod 6 releases the seal on one end of the delivery channel 10. Then, the liquid is transported to the circular plate 8 and the filter plate 4 through the delivery channel 10. After that, the liquid is discharged through multiple filter holes 5 on the filter plate 4, thereby achieving the drip irrigation effect.

[0036] When cleaning of the filter plate 4 is required, the flow of liquid into the connecting pipe 2 is repeatedly adjusted between being open and closed. This causes the conical rod 6, the transmission rod 7, the circular plate 8, and multiple needle rods 9 to move repeatedly left and right within the drip irrigation head 1. During this process, the connecting pipe 2 delivers liquid between the one-way valve 3 and the conical rod 6, gradually increasing the pressure between them. The conical rod 6, through the transmission rod 7, drives the circular plate 8 to slide synchronously within the drip irrigation head 1, compressing the spring 11. Simultaneously, the circular plate 8 drives multiple needle rods 9 to move back and forth. The needle rods 9 move synchronously, and one end of each needle rod 9 is inserted into the filter hole 5, thereby removing impurities that are clogging the filter hole 5 and preventing clogging. Then, the liquid is stopped from being supplied to the connecting pipe 2 and the liquid is discharged through the connecting groove 10, so that the pressure between the conical rod 6 and the one-way valve 3 gradually decreases. At this time, the elastic potential energy of the spring 11 causes the conical rod 6 to return to its original shape and prevent clogging at one end of the delivery groove 10, and causes the multiple needle rods 9 to disengage from the multiple filter holes 5.

[0037] Afterwards, by repeating the above operations for a period of time, the filter plate 4 can be cleaned.

[0038] The technological advancements of this invention compared to existing technologies are as follows: the cooperation of various components can prevent soil and debris from clogging multiple filter holes 5, thus avoiding affecting the normal operation of the entire device. Moreover, the structure is simple and the practicality is higher.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
