Description

Technical Field

[0001] This utility model relates to the field of water and fertilizer irrigation technology for quantitative fertilization of farmland, and in particular to a water and fertilizer irrigation device for quantitative fertilization of farmland. Background Technology

[0002] The farmland quantitative fertilization irrigation device is an essential piece of equipment used in farmland planting. It can irrigate plants with water and fertilizer at regular intervals and in fixed quantities to ensure healthy plant growth.

[0003] Regarding the existing technology patent CN216752752U, which discloses a garden quantitative fertilizer irrigation device, the device includes a timer controller, a spray pipe, a connecting pipe, a support frame, a connecting rod, an inlet pipe, and a pipe body. The timer controller is embedded in the top of the inlet pipe. The bottom end of the spray pipe and the top end of the connecting pipe are integrated. The connecting pipe is located above the support frame, and the top end of the support frame is welded to the bottom end of the pipe body. The left end of the connecting rod and the right end of the pipe body are integrated. The spray pipe includes an atomizing nozzle, a confluence channel, an outlet, a pressure groove, a connecting plate, a spring, a sliding spray block, a sealing ring, and a shell. This utility model achieves timed control by connecting the water delivery pipe to the inlet pipe. The device controls the water flow, directing it to the pipe body and spraying it out through the nozzles on the connecting pipe for irrigation. When not irrigating, the sliding nozzle on the nozzle is pulled by a spring, causing it to retract into the outer shell. This tightly connects the atomizing nozzle on the confluence channel with the sealing ring on the inner side of the outer shell, sealing the atomizing nozzle. This allows the irrigation device to automatically retract and seal the nozzles during use, preventing dust and debris from clogging them and affecting normal irrigation. However, existing water and fertilizer irrigation devices only spray water and fertilizer through nozzles, which cannot ensure uniform and wide-area irrigation, resulting in reduced efficiency of farmland irrigation and failing to meet the needs of farmland irrigation, thus having certain drawbacks.

[0004] Therefore, in response to the problem that existing water and fertilizer irrigation devices cannot effectively carry out large-scale sprinkler irrigation, cannot meet the needs of farmland irrigation, and reduce irrigation efficiency, a water and fertilizer irrigation device for quantitative fertilization of farmland can be designed. By installing sprinkler heads at the sprinkler pipe, large-scale sprinkler irrigation technology can be realized. At the same time, it can be installed and disassembled as needed to achieve high efficiency of farmland sprinkler irrigation and meet the needs of farmland sprinkler irrigation. Utility Model Content

[0005] In order to overcome the problem that existing water and fertilizer irrigation devices cannot effectively carry out large-scale sprinkler irrigation, cannot meet the irrigation needs of farmland, and reduce irrigation efficiency.

[0007] Preferably, the nozzle is inserted into the slot of the connecting pipe, and at the same time, the positioning blocks of the four ends of the nozzle are engaged in the positioning grooves. As it is inserted downward, the four positioning blocks are displaced into the movable grooves. By continuing to rotate, the positioning blocks come into contact with the insertion rod and are pressed to one end. When the insertion rod reaches the insertion hole position, it is ejected by the spring, so that the insertion rod is inserted into the insertion hole for fixation. At the same time, the sealing ring on the outside of the nozzle is also engaged in the sealing groove inside the connecting pipe for sealing.

[0008] Preferably, multiple evenly arranged truss rods are provided on both the left and right sides of the pipe body, and multiple evenly arranged support seats are provided at the bottom of the pipe body.

[0011] Preferably, a sealing ring is fitted onto the outside of the nozzle, and a sealing groove is provided on the inner wall of the connecting pipe, into which the sealing ring is inserted.

[0012] Preferably, the surface of the spray head has multiple evenly arranged spray holes, and a filter screen is provided at the front end of the spray holes.

[0013] Preferably, the sealing ring has a ring structure and is made of rubber.

[0014] The beneficial effects of this utility model are:

[0015] This farmland irrigation device for quantitative fertilization works by inserting a nozzle into a slot in a connecting pipe. Simultaneously, positioning blocks at the four ends of the nozzle engage with positioning grooves. As the nozzle is inserted downwards, the four positioning blocks shift into movable slots. Continued rotation brings the positioning blocks into contact with the insertion rod, pressing it to one end. When the insertion rod reaches the insertion hole, it is spring-loaded and ejected, securing the rod into the hole. Simultaneously, the sealing ring on the outside of the nozzle engages with the sealing groove inside the connecting pipe for sealing. This completes the installation of the connecting pipe. The nozzle can then be used to irrigate a large area of ​​farmland, significantly improving irrigation efficiency. Attached Figure Description
