Abstract

The utility model relates to an agricultural assembly type high-strength plastic tunnel framework with rope pulling, which is characterized in that two steel construction arch frames at the two ends with certain distance are connected by a plurality of longitudinally arranged high-strength steel strand horizontal wires, an inclined wire and a ground anchor wire can link the ground anchor and the steel construction arch frames together, twisted screws at the junction of the inclined wire and the ground anchor wire can be tightened, so the steel strand wires can be tightly pulled for forming a rope pulling plastic tunnel framework. The utility model has the advantages of low price, novel structure and convenient installation.

Description

Agricultural assembly type high-strength plastic tunnel framework with rope pulling

The present utility model agripast canopy skeleton.

In agricultural production, plastic greenhouse is widely used in the early stage production of various crops, and the output of crops is doubled and redoubled, and has very big economical, societal benefits.At present, the plastic greenhouse skeleton that generally uses both at home and abroad mainly contains three types.The one, coating steel pipe assembled skeleton; The 2nd, the reinforcing bar welded framework; The 3rd, bamboo bar (or batten) skeleton.More than three kinds of its structures of skeleton roughly the same, all be the continuous arrangement architecture of arch form bearing support, roughly 50～100 centimetres of bow member spacings.Difference only is on the material therefor.Steel pipe and framework of steel reinforcement serviceability are good, do not have support column in the canopy, farming, the management all very convenient, grow service life (10～15 years).The problem that exists is that cost is higher, and every construction cost per square meter is 18～20 yuan, build 100 square metres plastic greenhouse skeleton, needs 1800～2000 yuan of costs, and further large tracts of land popularization difficulty is bigger.Bamboo bar (or batten) though skeleton cost lower (3～4 yuan every square metre), undercapacity, serviceability is poor, rots easily the life-span short (2～3 years).Need upright support column in the canopy, farming inconvenience.In addition, back two kinds of skeletons are not assembleds, and inconvenient commercialization production can only be built at the scene, build trouble, the dismounting difficulty.

That the purpose of the present utility model is to produce is cheap, function admirable, anticorrosion agripast canopy skeleton durable, easy for installation, realizes the suitability for industrialized production manufacturing, makes the large scale application of plastic greenhouse become possibility.

The plastic greenhouse skeleton that the present utility model is designed, on structure, be different from the continuous spread pattern of traditional bow member fully, it has adopted unique cord pulling type structure, high strength steel hinge line with vertical arrangement has replaced transversely arranged steel pipe (or reinforcing bar) bow member, the bow member number reduces to 1/10th, thereby reduced cost significantly, it is 6～8 yuan that rope draws the expense of every square metre on canopy skeleton.Owing to adopted fabricated construction, loaded and unloaded very convenient.Least life can reach 15 years.

Main points of the present utility model are: the steel construction bow member that two ends are separated by a distance couples together with the high strength steel hinge horizontal drawing line of the layout of some vertical cloth, with lateral conductor and ground anchor earth anchor and steel construction bow member are coupled together again, tighten at last be in lateral conductor and anchor junction, ground spending blue screw that the steel strand wires tension is formed rope to draw the plastic greenhouse skeleton.

Drawings and Examples:

Fig. 1 draws the plastic greenhouse skeleton for agricultural assembled high strength rope.

Fig. 2 is that the agricultural assembled high strength rope of skeleton draws the plastic greenhouse skeleton in the middle of being provided with.

Fig. 3 not double-layer plastic canopy draws the plastic greenhouse skeleton with agricultural assembled high strength rope.

In accompanying drawing 1, (1) is earth anchor, and (2) are the ground anchors, and (3) are to spend blue screw, and (4) are lateral conductors, and (5) are bow members, and (6) are hooks, and (7) are the horizontal drawing lines.

Embodiment 1:

Its installation method is: see accompanying drawing 1, two parallel lines separated by a distance (standoff distance is identical with the length of plastic greenhouse) on the ground draw earlier.Assembling bow member (5) stands on two equality lines afterwards separately, and with the rod supporting, in case topple over.On the appropriate location in the outside of two bow members, respectively dig out rectangular ground anchor pit, cheat dark more than one meter.Earth anchor (1) is inserted in ground anchor (2) collar rammer to be buried.Then with horizontal drawing line (7), bow member (5), lateral conductor (4), after anchor (2) all connects, tighten and spend blue screw (3) to make horizontal drawing line (2) be in tensioned state to get final product.

Embodiment 2:

The plastic greenhouse of length more than 30 meters, mesozone need be set up 1～3 bow member, and middle bow member (9) will be with spending blue screw (8) to be connected with both sides horizontal drawing line, and the degree of tightness of horizontal drawing line is with spending blue screw to regulate (seeing accompanying drawing 2).

Embodiment 3:

The double-layer plastic canopy can dispose column on bow member, the horizontal drawing line can draw bilayer, for the usefulness (seeing accompanying drawing 3) of double-layer plastic canopy.

Draw the plastic greenhouse skeleton at above-mentioned rope, steel construction bow member described in the utility model (5) is to be assembled with many angle steel or steel pipe, assembling adopts bolt to connect (connecting plate can be arranged in addition) or sleeve pipe connects, and bow member also will dispose hook on (5), and its number is identical with horizontal drawing line number.Horizontal drawing line, lateral conductor and ground anchor adopt galvanized strand wires, also can adopt plastic-coated steel twisted line and galvanized steel wire rope, it is better that steel strand wires put the flexible plastic tube effect, can reduce the wearing and tearing of plastic foil, the ovalisation collar is done at the two ends of every steel strand wires, so that interconnect with other parts.

Agricultural assembled high strength rope draws the plastic greenhouse skeleton to be mainly used on the plastic house culture of seedling cultivation of rice, vegetables production and other crops (as tobacco, medicinal material), it forms two ends steel construction bow member with the tension of high strength steel strand horizontal drawing line, because the numerous bearing supports in the canopy replace with steel hinge line, thereby make this agricultural assembled high strength rope draw plastic greenhouse skeleton price to hang down modest, novel structure, easy for installation, therefore, has very remarkable economic efficiency.

Claims
