However, the existing spray hose still has defects and deficiencies in some aspects that need to be improved:

[0003] For example, the application number is CN201420644857.2, which is a special hose for agricultural sprayers with exquisite design, convenient installation and use, resistance to ultraviolet radiation, strong weather resistance and long service life. The hose comprises a polyurethane hose, a connecting pipe head, a nut and an annular silicone sealing pad; the two ends of the polyurethane hose are respectively connected to a nut through the connecting pipe head, the annular silicone sealing pad is arranged in the nut, and the connecting pipe head is a special joint for sprayers with an inner diameter of 5mm and an outer diameter of 8mm. The special hose for agricultural sprayers has exquisite design, exquisite appearance, convenient installation and use, good sealing, and more significant corrosion resistance, weather resistance and temperature resistance. It is also resistant to ultraviolet rays, not easy to oxidize and weather, can be exposed to the sun for a long time, has a longer service life, is beneficial to environmental protection and saves raw materials, and perfectly solves the defects of traditional sprayer hoses.

[0004] The spray hoses in the above documents are mostly made of single-layer PVC material. The wear resistance of the single-layer hose is poor. After a long period of operation, the hose may break, thus affecting the subsequent use;

[0005] The spray hose in the above document has low toughness. When the hose is in spraying operation, the inside of the hose will be deformed due to the pressure of water pressure, and the hose may even be damaged.

[0006] Therefore, we propose a spray hose with a reinforced braided structure to solve the above-mentioned problems. Utility Model Content

[0008] To achieve the above object, the utility model provides the following technical solution: a spray hose with a reinforced braided structure, comprising an inner plastic layer, an outer plastic layer is arranged outside the inner plastic layer, and a wear-resistant layer is arranged at the outer end of the outer plastic layer;

[0009] A connecting layer, wherein the connecting layer is fixedly connected to the outer side of the inner plastic layer, and a connecting groove is provided inside the connecting layer;

[0010] A braided layer, wherein the braided layer is fixedly connected between the outer plastic layer and the connecting layer;

[0011] The wear-resistant protrusion is fixedly connected to the outer side of the wear-resistant layer.

[0012] Furthermore, the connection grooves are distributed in an annular array with respect to the connection layer, and a reinforcing bar is fixedly connected inside the connection groove, and the reinforcing bar is connected to the inner plastic layer.

[0013] Furthermore, the reinforcement strip is cylindrical and flexible.

[0014] Furthermore, a woven mesh is arranged inside the woven layer, and the woven mesh is woven by a plurality of crisscrossed reinforcing fiber filaments and twisted industrial filaments.

[0015] Furthermore, the woven net is woven into a tight plain weave shape, and the reinforcing fiber filaments and the industrial filament twisted filaments are interlaced with each other.

[0016] Furthermore, an elastic connecting rope is provided through the interior of the wear-resistant layer, and the elastic connecting rope is vertically distributed along the length of the hose.

[0017] Furthermore, the wear-resistant protrusions are in the shape of relatively flat long strips, and there are multiple groups of wear-resistant protrusions distributed vertically along the outer circle of the wear-resistant layer.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The double-layer design of the inner plastic layer and the outer plastic layer can enhance the strength of the hose itself and reduce the possibility of the hose being easily damaged by the single-layer material;

[0020] 2. A reinforcement strip is arranged inside the connection layer, which can improve the toughness of the connection layer itself. The design of multiple connection layer reinforcement strips can reduce the possibility of the hose breaking during longitudinal stretching and folding, and further improve the toughness of the hose;

[0021] 3. The braided layer is arranged between the outer plastic layer and the inner plastic layer. Through the interlaced weaving design of the woven mesh in the braided layer, the inner plastic layer can be wrapped and protected, so that the outer side of the inner plastic layer is supported, the structure of the inner plastic layer is enhanced, the possibility of deformation of the pipe body due to the internal water pressure is reduced, and the high pressure resistance strength of the inner plastic layer is increased;

[0022] 4. The elastic connecting rope set inside the wear-resistant layer can increase the toughness of the wear-resistant layer to a certain extent, making the connection of the wear-resistant layer more precise and reducing the possibility of cracking and separation of the wear-resistant layer due to long-term operation;

[0023] 5. The wear-resistant protrusions are arranged on the outside of the wear-resistant layer, which further enhances the wear resistance of the hose and increases the service life of the hose. BRIEF DESCRIPTION OF THE DRAWINGS
