A kind of tomato greenhouse support

Abstract

The invention relates to the technical field of greenhouse sheds, in particular to a tomato shed bracket. The tomato shed bracket comprises arch-shaped brackets and pull rods which are used for connecting every two adjacent arch-shaped brackets, wherein each arch-shaped bracket comprises a connecting fitting, a first supporting rod and a second supporting rod; each first supporting rod and each second supporting rod are connected to two ends of the corresponding connecting fitting, each first supporting rod is bended to form a first arch-shaped part, each second supporting rod is bended to form a second arch-shaped part, a supporting rod for supporting a downward concave part is arranged under each connecting fitting, and each supporting rod adopts a telescopic structure. The tomato shed bracket disclosed by the invention is simple in structure, high in intensity and high in carrying capacity; the structure of the tomato shed bracket has higher carrying capacity than that of the structure of a wide-span plain-arch shed; in addition, the supporting rods adopting the telescopic structure are arranged and used for supporting the first supporting rods and the second supporting rods, so that the carrying capacity of the shed is further improved, the bending degree of the first arch-shaped parts and the bending degree of the second arch-shaped parts can be adjusted through adjusting the length of the supporting rods, and the supporting intensity of the arch-shaped brackets is adjusted.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a tomato greenhouse bracket. Background technique [0002] At present, the more practical greenhouses generally include single-span greenhouses, multi-span greenhouses, sunlight greenhouses, simple plastic arch sheds, etc. Among them, the advantages of single-span greenhouses are that they are convenient for rain drainage, and the snow load can automatically slide off when the shed surface angle is above 15 degrees. Good ventilation and heat dissipation, the disadvantages are large heat dissipation in winter, high cost, and not easy to scale up; the advantages of multi-span greenhouses are high land utilization rate, good thermal insulation performance, large span, large space, easy for mechanized and centralized management, and the disadvantages are natural ventilation ability Poor, no snow-covered load sliding function, high requirements for structural strength, high cost, ...

[0002] At present, the more practical greenhouses generally include single-span greenhouses, multi-span greenhouses, sunlight greenhouses, simple plastic arch sheds, etc. Among them, the advantages of single-span greenhouses are that they are convenient for rain drainage, and the snow load can automatically slide off when the shed surface angle is above 15 degrees. Good ventilation and heat dissipation, the disadvantages are large heat dissipation in winter, high cost, and not easy to scale up; the advantages of multi-span greenhouses are high land utilization rate, good thermal insulation performance, large span, large space, easy for mechanized and centralized management, and the disadvantages are natural ventilation ability Poor, no snow-covered load sliding function, high requirements for structural strength, high cost, not suitable for places with particularly large snow volume; solar greenhouse is a more popular planting method in protected areas in northern China, and its advantages are low cost, High thermal insulation performance, but the disadvantages are low land utilization rate, small individual scale, which is not conducive to mechanized and centralized management. Although it has a certain sliding function of rain and snow loads, the increase of its single area is still limited by its structure's load bearing capacity for heavy snow loads. Ability; simple plastic arch shed is a popular planting method in protected areas in southern China. Its advantages include low cost and certain environmental control capabilities. The disadvantages are low land utilization rate and small individual scale, which is not conducive to mechanization and centralized management. Although it has a certain ability to slide under rain and snow loads, its structural strength is low, resulting in a large number of plastic sheds collapsing due to rain and snow every year

All of the above structures have conflicts between the demand for the span of the greenhouse and the structural strength, the number of pillars, and the cost. If the span of the greenhouse is increased, the pillars will be added, which will lead to inconvenient operation management; or the structural strength will be increased to increase the strength standards of beams and pillars. , leading to a substantial increase in cost, and a substantial increase in its self-weight load
