Description

Agricultural steelframe plastic tunnel

Technical field

The utility model relates to a kind of agricultural booth, especially a kind ofly is used for crops such as culturing vegetable, flowers, fruit tree, can insect protected and according to the steelframe plastic tunnel of regulating temp. and humidity season.

Background technology

Agricultural booth is a kind of in people's necessity configuration of crops such as culturing vegetable, flowers under the condition of subenvironment for a change, is generally the steelframe booth, in traditional agricultural booth, the ubiquity shoulder height is lower, generally have only 1～1.1m, the both sides ventilating opening is less, and the booth two ends are all covered by plastic sheeting for farm use.Because ventilating opening is less, it is not smooth to ventilate, and summer temp is too high, temperature of shed, humidity regulation ability a little less than, especially run into insect pest serious the time, can't resist the infringement of insect pest again, use the agricultural chemicals deinsectization in the booth, easily cause vegetables to pollute, be unfavorable for health of people.

The utility model content

The purpose of this utility model is that the problems referred to above at traditional steelframe booth exists provide a kind of novel agricultural steelframe plastic tunnel.

The purpose of this utility model is achieved in that a kind of agricultural steelframe plastic tunnel, comprises at least two supporting steel frame proper alignment composition space frameworks that structure is identical, and is covered in the booth that the plastic film on the space framework forms, and it is characterized in that:

A) described supporting steel frame top is an arch, and the two ends of arch are the leg of symmetry, and the leg symmetry is opened outward, and its lower ending opening is greater than upper end open;

B) the arch peak of the supporting steel frame of booth is the canopy height to the distance on ground, and the both sides of booth are shoulder, and the leg top is the shoulder height of booth to the distance on ground, and the distance of leg lower end is a span, the high 2.5～3.4m of described canopy, span 6～8m, shoulder height 1.2～1.8m;

C) at least one pull bar fixedlyed connected one by one with each supporting steel frame top;

D) end of booth is provided with the gate, and the both sides and the two ends of booth are equipped with vent window, are coated with fly net or plastic film on gate and the vent window.

In the utility model: described canopy height is 3.3m, and span is 8m, and shoulder height is 1.8m;

In the utility model: all contain draw-in groove on the gate of booth and the frame of vent window, described fly net or plastic film are fixed on gate and the vent window by the jump ring of coupling.

In the utility model: the top of both sides vent window is concordant with the shoulder top, the high 2m in the top of two ends vent window; The lower edge of described each vent window is to being the skirt film between the ground, and the height of skirt film is 50cm.

In the utility model: the mesh of described fly net is 18～25 orders.

In the utility model: the mesh of described fly net is 20 orders.

Advantage of the present utility model is: owing to be coated with fly net or plastic film on gate and the vent window, can make booth have the temp. and humidity regulating power; Large span, higher canopy height and shoulder height make in the booth more spaciously, have especially also set up vent window at the booth two ends, not only make booth that the vent window of enough height is arranged, and it are more smooth and easy to ventilate, and has improved temperature of shed, humidity regulation ability; Because be equipped with draw-in groove on the frame of the gate of booth and vent window, fly net or plastic film are furnished with the jump ring of coupling, can be as required in the use, or select plastic film, or select fly net, very convenient; Because the mesh of fly net is 20 orders, can prevent the infringement of polypide crops in the booth of the above insect of 1mm.

Embodiment

Accompanying drawing discloses the basic structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model embodiment is further described.

As seen from Figure 1, the top of supporting steel frame is arch top 1 in the utility model, and the two ends on arch top 1 are the leg 2 of symmetry, outer the opening of leg 2 symmetries, and its lower ending opening is greater than upper end open; The arch peak of the supporting steel frame of booth is the canopy height to the distance on ground, and the both sides of booth are shoulder, and leg 2 tops are the shoulder height h of booth to the distance on ground, the distance of two leg lower ends is a span, generally speaking, and the high 2.5～3.4m of canopy, span 6～8m, shoulder height 1.2～1.8m.

As seen from Figure 2, agricultural steelframe plastic tunnel comprises at least two supporting steel frames composition space frameworks that structure is identical, and at least one pull bar fixedlyed connected one by one with each supporting steel frame top arcuate top 1; And the booth that plastic covering plastic sheeting for farm use 3 forms on space framework, an end of booth is provided with gate 5, and the both sides of booth and two ends are equipped with vent window 4, are coated with fly net or plastic film 3 on gate 5 and the vent window 4.

Fig. 3 discloses the structure of a kind of draw-in groove 6 and jump ring 7.All contain draw-in groove 6 as shown in the figure on the frame for the ease of the gate 5 of booth and vent window 4, described fly net or plastic film are fixed on gate 5 and the vent window 4 by the jump ring 7 of coupling.

During concrete enforcement, the top of both sides vent window 4 is concordant with the shoulder top, and the top of two ends vent window 4 is higher than shoulder height and concordant with 5 tops, gate, and it highly is 3/5 canopy height; The lower edge of described vent window 4 is to being the skirt film between the ground, and the height of skirt film is 50cm.In the present embodiment, the canopy height is 3.3m, and span is 8m, and shoulder height is 1.8m.

Annual 5～October, the plastic film 3 on vent window 4 and the gate 5 can be replaced by fly net, the mesh of fly net is 20 orders.In other months, what vent window 4 and gate 5 disposed is plastic film 3.The interior temperature of booth in summer reduces by 3～8 ℃ than traditional booth, and spring and summer humidity ratio in autumn tradition booth reduces by 40%, and fly net can prevent the intrusion of the above insect of 1mm.
