Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation equipment technology, specifically relating to a direct-insertion agricultural irrigation water hose. Background Technology

[0002] Irrigation is a crucial agricultural activity. Currently, flood irrigation remains the primary method, but this method, after the water hose guides the water flow into the farmland, easily creates waterlogged areas due to the impact of the water flow, affecting sowing. Furthermore, with only one outlet, water supply efficiency is low, and it cannot provide even irrigation to the entire farmland. In the field of agricultural irrigation, low-pressure (≤3 bar) hose systems have become the core facility for modern farmland irrigation due to their advantages such as water conservation, energy saving, and ease of deployment. Existing irrigation hose connection technologies with branch pipes generally have the following drawbacks: For example, high-pressure design redundancy; traditional quick-connect structures are mostly designed for 5-10 bar industrial pressure. These systems use internally threaded connectors (nuts) on the hose, and branch pipes are connected to the hose nut via externally threaded guide pipes (hollow screws). The threaded connection structure requires tools to tighten, often necessitating the use of PTFE tape, which is cumbersome and time-consuming. Some systems use external clamps for fixing, which suffers from cumbersome installation, wasteful material costs, and poor reusability. Therefore, this utility model provides a direct-insertion agricultural irrigation hose that is suitable for low pressure (≤3 bar), has a simple structure, is easy to operate, has reliable sealing, and is easy to install quickly, in order to solve the above-mentioned technical problems.

[0006] The inner surface of the docking part is a first cylindrical cavity, and the outer surface of the branch water pipe connector is provided with a matching first gradually expanding conical sealing surface.

[0011] In some embodiments, the docking portion is provided with a tapered annular groove, and the end of the branch water pipe connector forms an annular insertion edge that can be elastically inserted into the tapered annular groove.

[0012] The overlapping block is a ring-shaped structure that extends radially outward from the connecting base and is integrally injection molded. The overlapping block can be bonded to the inner wall surface of the main pipe by hot melt, waterproof adhesive, or ultrasonic welding.

[0013] As a further embodiment of this utility model, the branch water pipe connector is provided with a standardized interface for connecting to an external branch hose.

[0014] As a further embodiment of this utility model, the branch water pipe connector is a T-shaped tee structure, and each branch water pipe connector can connect two external branch hoses. In some embodiments, the branch water pipe connector can also be a four-way or five-way structure.

[0015] During use, if some of the connecting bases are not needed for connecting branch water pipes, the connecting bases can be blocked by a water-stopping component that is closed at the top and has the same structure as the branch water pipe connector at the bottom.

[0016] The advantages of this utility model are: simple structure and easy to use; effectively avoids damage to farmland caused by water flow impact during irrigation, which is beneficial to sowing; branch water pipe connectors can be easily connected to branch water pipe fittings through the branch water pipe connectors on the water hose, and water can be supplied to multiple locations in the farmland through the branch water pipe fittings, improving water supply efficiency; simple field operation, no need for tools, and no need for excessive insertion and extraction force, which can achieve a quick and reliable sealed connection between the branch water pipe fittings and the connecting base, improving the user experience.
