Abstract
A plastic-coated hose easy to pull and resistant to abrasion comprises an outer plastic layer, a woven bag and an inner plastic layer, wherein the woven bag is arranged between the outer plastic layer and the inner plastic layer, and an abrasion-resistant protruding body is arranged on the outer surface of the outer plastic layer. The structure not only improves the abrasion resistance of the plastic-coated hose, reduces the pulling resistance of the plastic-coated hose, but also improves the pressure resistance of the plastic-coated hose, and prolongs the service life.
Description
Technical field:
The present invention relates to a kind of water delivery hose, relate in particular to a kind of agricultural irrigation plastic-coated hose.
Background technique:
In manufacturing operation process that the farming kind is watered, usually use plastic-coated hose as conduit pipe, during use, to launch, length can connect arbitrarily fast, and the used time can not dismantled rolling.The structure of existing plastic-coated hose as shown in Figure 1, it comprises outer plastic layer 1, knits bag 2 and outer plastic layer 3, knit a bag centre that is arranged on outer plastic layer and interior plastic layer, the surface of outer plastic layer is to leave the level and smooth cylndrical surface of knitting the landing net line, because distance is always deposited in the water place of operation and the place of putting of diesel engine water pump assembly of needs, watering water area is determined by plastic-coated hose length, when operation, people must draw water delivery hose at any time as required, due to ground relief to be watered, in the dilatory using process of reality, there is the defect of following several respects:
The first, plastic-coated hose contacts with ground, in dilatory process, certainly leads to friction between the two, constantly pulls friction can make the plastic-coated hose friction damage, the working life of dwindling plastic-coated hose;
The second, when water delivery, the weight of the body of plastic-coated hose is large, and large with contact area of ground, and trail drag force is large, and dilatory gruelling, labor intensity is large;
The 3rd; the compressive strength of same size plastic-coated hose is not high; because can there be a segment distance destination that needs water delivery with the water pump place usually; this just need to constantly drag on the ground to the whole piece water delivery hose; just can guarantee that water delivery hose can water the end of scope by the water need of spraying; in this process; the dilatory friction of water delivery hose makes outer plastic layer be worn gradually; thereby cause the voltage endurance capability of whole water delivery hose to descend; if can producing body, the water delivery overpressure breaks, directly reduction of service life.
Summary of the invention:
In order to overcome existing plastic-coated hose above shortcomings, the purpose of this invention is to provide a kind of easy-to-draw wear-resisting plastic-coated hose, it not only improves the wear-resistant ability of plastic-coated hose, reduces the trail drag force of plastic-coated hose, can also improve the voltage endurance capability of plastic-coated hose, improve working life simultaneously.
The technological scheme that the present invention takes is:
A kind of easy-to-draw wear-resisting plastic-coated hose, comprise outer plastic layer, knit bag and interior plastic layer, the described bag centre that is arranged on outer plastic layer and interior plastic layer of knitting, and it is characterized in that: the outer surface of plastic layer is provided with wear-resisting convex body outside.
Further, described wear-resisting convex body is the strip convex body, and the strip convex body is parallel with the plastic-coated hose axis, and circumferentially being uniformly distributed along body.
Further, the protrusion height of described strip convex body is 0.5～3 millimeter, and the angle between adjacent two strip convex bodys is 1 °～15 °.
Further, the sectional shape of described wear-resisting convex body is triangle.
Further, the sectional shape of described wear-resisting convex body is semicircle.
Further, the sectional shape of described wear-resisting convex body is quadrilateral.
Further, the sectional shape of described wear-resisting convex body is semicircle and tetragonal combination.
Further, described quadrilateral is rectangle or trapezoidal.
Further, described wear-resisting convex body, for the block convex body of point, is evenly distributed on the outer surface of outer plastic layer of plastic-coated hose.
Further, the protrusion height of putting block convex body is 0.5～3 millimeter.
Be provided with the some wear-resisting convex bodys parallel with the body axis on individual surface due to the outer plastic layer of plastic-coated hose of the present invention, thereby reduced the area of contact on whole piece plastic-coated hose and ground, in actual use, when the dilatory body of needs, only there is wear-resisting convex body to contact with ground, reduced trail drag force, decrease operator's labor intensity, what at first plastic-coated hose wore and tore is wear-resisting convex body, the pressure-bearing tube wall of plastic-coated hose is unaffected, thus the working life of having improved plastic-coated hose.Simultaneously, bearing capacity and the tensile strength that the raising plastic-coated hose is set of wear-resisting convex body.
The surplus of resistance to wearing of the present invention has increased by 0.5～3 millimeter, can extend 2 years working life～3 years; Trail drag force reduces 50%～70%, has alleviated greatly operator's labor intensity; Tensile strength and bearing strength have improved 15%～30%, through reality, use checking, the present invention compared with prior art: have wear-resistantly, easily pull, bearing strength, tensile strength are high, the characteristics of long service life.
