[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] Please refer to Figs. 1-2 In the embodiment, an anti-blocking drip irrigation device comprises a head tube 1, a lower tube 12 and a ground insertion 9, the front surface of the head tube 1 is provided with an interface 4 connected with the inner cavity, the bottom is provided with a plurality of drippers 8 in a ring path, the top of the head tube 1 is provided with a threaded hole connected with the inner cavity, the diameter of the threaded hole is larger than the diameter of the inner cavity, the threaded hole is connected with a plug 2 extending into the inner cavity by threads, the lower tube 12 is connected with the inner side of the bottom of the head tube 1 by threads and is connected with each other, and a telescopic assembly capable of sealing the water outlet of the head tube 1 is installed inside, the top end of the telescopic assembly is attached to the bottom of the plug 2, the ground insertion 9 is connected with the outer side of the bottom of the head tube 1 by threads, the lower tube 12 is covered inside, and the outer side is further provided with a ring cylinder 10, the drippers 8 are covered inside the ring cylinder 10, and the outer side of the ring cylinder 10 is provided with the same number of water outlets 11 as the drippers 8.

[0019] In the structure, the lower pipe is threadedly connected with the ground plug and the head pipe, facilitating subsequent disassembly, collection, replacement and cleaning. The ground plug is inserted into the ground to provide positioning. The external water pipe is connected with the interface, and the water source is introduced into the ring cylinder through the dripper and then dripped outside through the water outlet, thereby expanding the drip irrigation range. The ring cylinder covers the bottom of the head pipe, and the dripper is located inside, thereby protecting the dripper from being blocked by dirt, dust and other impurities, and ensuring normal operation. When the drip irrigation device is not needed, the plug is rotated upward and then lifted by the telescopic assembly, thereby plugging the water outlet of the head pipe to complete the closure and stop using.

[0020] The telescopic assembly includes a piston rod 6 connected inside the lower pipe 12. The flow channel of the lower pipe 12 has a wide upper part and a narrow lower part. The piston rod 6 has a spring 7 sleeved on the outer side. The spring 7 is located in the wide flow channel of the lower pipe 12. The diameter of the piston rod 6 is adapted to the narrow flow channel, and the piston rod 6 seals the narrow flow channel to prevent water overflow. The top of the piston rod 6 is conical, and the top end is adapted to the water outlet of the head pipe 1. In the normal working state, the plug is in a tightened state. The plug presses the piston rod downward to overcome the elastic force of the spring and move downward to open the water outlet of the head pipe, and the water flow can pass smoothly. When it is needed to be closed, the spring pushes the piston rod upward, so that the conical top of the piston rod tightly fits the water outlet of the head pipe to achieve sealing and prevent impurities from entering the pipeline to cause blockage.

[0021] The plug rod of the plug 2 is located in the inner cavity of the head pipe 1, and the plug rod is divided into an upper segment, a middle segment and a lower segment. The diameter of the upper segment is the same as the diameter of the inner cavity, thereby achieving sealing. The diameter of the middle segment is smaller than the inner cavity, thereby reserving a certain space in the inner cavity for the joint to inject water. The lower segment extends to the water outlet of the head pipe 1 and tightly fits the top end of the piston rod 6. The diameter of the lower segment is smaller than the water outlet, so that the piston rod can be pushed to open the water outlet during the lifting of the plug. In this state, the drip irrigation device is in an open mode. When the plug is screwed upward, the piston rod is closed by the spring to achieve a closed state. Therefore, the opening and closing of any group of drip irrigation devices can be adjusted according to environmental requirements.

[0022] Further, the outer side of the upper segment of the plug rod of the plug 2 is provided with a ring groove, and a sealing ring 3 tightly fitted with the inner cavity is installed in the ring groove. The sealing ring can improve the sealing of the plug on the inner cavity.

[0023] The working principle of the above embodiment is as follows:

[0024] Firstly, the ground plug is inserted into the soil, the device is ensured to be stable, the water supply pipe is connected through the interface, after the water enters the head pipe, according to the actual irrigation requirement, the plug is rotated to push the piston rod to move downward, the lower water outlet of the head pipe is opened, the water is drip irrigated into the soil through the water outlet of the drip head and the ring barrel, when the irrigation is finished or the drip irrigation of a certain area needs to be stopped, the plug is screwed up, the spring pushes the piston rod to move upward, the lower water outlet of the head pipe is sealed, the impurities in the soil are prevented from flowing backward into the pipe, during the whole irrigation process, the ring barrel can not only guide the water flow, but also can reduce the influence of external impurities on the drip head to some extent, and the anti-blocking performance of the device is further improved.

[0025] The whole work flow is ended, and the contents not described in detail in the specification all belong to the prior art known by the person skilled in the art.
