Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a kiwifruit multi-span greenhouse integrating rain shelter and traction functions. Background Art

[0002] Continuous rain is a common natural disaster weather that harms the production of fruit trees in the south. It can occur throughout the year. The greatest impact on fruit trees is continuous rain in spring and early summer, which is the critical period for fruit trees such as flowering, flower bud differentiation, and fruit ripening. If there is continuous rainy weather, it is easy to cause difficulties in pollination and fruit setting, incomplete flower bud differentiation, and increased fruit cracking and falling, resulting in low final fruit quality, low yield, and low benefits.

[0003] At present, the preventive measure for continuous rain is usually to build a rain shelter above the fruit trees. The existing rain shelter structure generally adopts a relatively simple steel frame support structure, and rainwater is blocked by laying a rain shelter film on the steel frame. However, such a rain shelter does not have the function of traction of fruit tree vines, so it is not suitable for fruit trees with many vines such as kiwi fruit, because fruit trees with many vines are generally picked for hanging fruits, and their vines will spread over a large area. The traditional traction structure is generally a flat trellis, and both new and old vines grow on the flat trellis, crisscrossing and disorderly, and will cause the ventilation and light transmission of fruit and vegetable vines to deteriorate, which is not conducive to production management and product quality control.

[0004] In order to achieve the above two functions at the same time, the two structures are generally simply superimposed, that is, a rain shelter is built above the traction structure. However, such a simple combination will make the overall structure too complicated, with many components, difficult installation and high manufacturing costs. Therefore, it is urgent to design a kiwifruit greenhouse that can perfectly adapt to the functions of rain shelter and fruit tree traction at the same time, simplify the overall structure to reduce the difficulty of installation and manufacturing costs.

[0035] Example 2 This embodiment is a further supplementary solution to the embodiment 1. In this embodiment, both sides of the greenhouse film 6 along the width direction of the shed body are equipped with automatic film rolling devices.

[0036] More specifically, the automatic film rolling device includes a film rolling tube 12, an electric film rolling machine 13 and a guide telescopic rod 14. The film rolling tube 12 adopts a φ36×1.2mm or φ51×1.2mm card slot integrated film rolling tube. The film rolling tube 12 is placed on the outer arch surface of the main arch rod 4 along the length direction of the scaffolding body, and the tube body of the film rolling tube 12 is connected to the end of the shed film 6; two electric film rolling machines 13 are provided, and the two electric film rolling machines 13 are respectively installed at the two end ends of the film rolling tube 12; the guide telescopic rod 14 is installed on the end faces of the scaffolding body, and one end of the guide telescopic rod 14 is fixedly connected to the electric film rolling machine 13, and the other end is rotatably connected to the end face upright 9.

[0037] In this embodiment, the working principle of the automatic film rolling device is as follows: the film rolling tube 12 is driven to rotate by the electric film rolling device 13, so that the greenhouse film 6 is rolled up on the film rolling tube 12 and the film rolling tube 12 is pulled to move toward the roof, and the guide telescopic rod 14 rotates following the movement of the film rolling tube 12 and the electric film rolling device 13, and its function is to prevent the film rolling tube 12 from being displaced in the front and rear directions when the film is rolled; the automatic film rolling device can slowly roll the greenhouse film 6 on the main arch rod 4 from the top of the shed body to the roof in the absence of rain. It rises to achieve ventilation and cooling inside and outside the shed, and slowly lowers when it rains to achieve shelter from the rain. At the same time, the automatic film rolling device is also equipped with an intelligent control system, which can monitor the weather and temperature changes inside and outside the shed in real time, and then control the automatic film rolling device to perform corresponding work, so as to switch the ventilation or rain shelter state in time, without manual control, which is more convenient. The specific control principle is as follows: the film is automatically rolled up when the temperature is ≥40℃ and the wind force is ≥10m / s in summer, and the film is automatically lowered when the temperature is <10℃ and the daily rainfall is ≥5mm in winter.

[0038] It should also be noted that if the length of the scaffolding body exceeds 80m, the shed film 6 on the entire scaffolding body needs to be broken into two sections, and automatic film rolling devices are respectively configured on the two sections of the shed film 6 to avoid the problem of excessive resistance caused by the shed film 6 being too long; a film pressing rope is added within the length of each column 1 to avoid the problem of the shed film 6 being separated from the outer arch surface of the scaffolding body and being difficult to roll up. Furthermore, if Figure 3 As shown, a small shielding frame 15 is installed on the top of the shed body along its length direction. The small shielding frame 15 includes a support rod 151 and a shielding plate 152 fixedly installed above the support rod 151. The lower end of the support rod 151 is connected to the main arch rod 4, and the lower part of the shielding plate 152 is a shielding space. The small shielding frame 15 is used to shield and protect the rolled-up shed film 6 after the shed is rolled and ventilated, so as to prevent the shed film 6 from being exposed to direct sunlight for a long time or being soaked in rain, which may cause the shed film 6 material to age and deform, affect its original shape and function, and extend its service life.

[0039] Furthermore, if Figure 4 As shown, in order to drain the rainwater between the tops of the two single shed bodies, the longitudinal beam 2 is configured as a water guide trough, and water pipes are installed at the notches at both ends of the longitudinal beam 2. It should be understood that the water pipes are used to safely discharge the rainwater in the trough on the roof to the ground to avoid splashing water; inwardly recessed roll film tube placement grooves are also provided on both sides of the upper end of the longitudinal beam 2. When the shed film 6 is in a fully closed state, the roll film tube 12 is placed in the roll film tube placement groove to tighten the shed film 6 to keep it taut, thereby avoiding gaps that may cause heat loss or rain leakage.

[0040] Example 3 This embodiment is a further supplement to Embodiment 1. In this embodiment, the end face uprights 9 arranged in the end faces of both ends of the trellis body and the high-position cables 10 connected to the end face uprights 9 are provided in plurality according to the number of planting ridges covered by the single trellis body, and the end face uprights 9 and the high-position cables 10 are installed in the middle position of two adjacent rows of planting ridges; the lower end of the traction rope 11 is connected to the low-position load-bearing cable 8 corresponding to the top of the planting ridge which is closest to the horizontal distance on both sides of the high-position cable 10.

[0041] In this embodiment, the number of planting ridges covered by the single shed body is three rows, and the positions of the three rows of planting ridges correspond to the positions of two rows of columns 1 and the middle position of the two rows of columns 1, respectively. Therefore, the end face uprights 9 provided in any end face of the shed body are arranged as two left and right pieces, and correspondingly, two high-position cables 10 are also arranged. The traction ropes 11 on the high-position cables 10 are obliquely pulled along both sides of the high-position cables 10 to the low-position load-bearing cables 8 corresponding to the positions of the two rows of columns 1 and the middle position of the two rows of columns 1.

[0042] Furthermore, the connection points of the traction ropes 11 connected to the same high-position cable 10 and diagonally connected along the left and right sides are staggered on the high-position cable 10 to avoid entanglement of vines at the top of the traction ropes 11 caused by the traction ropes 11 diagonally pulled to the left and right sides on the same high-position cable 10.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
