Pest-resistant rainproof shed

Abstract

The invention discloses a pest-resistant rainproof shed. A plurality of reinforced concrete upright columns are fixed on the ground in a matrix arrangement mode; longitudinal beams are fixed at upper ends of the reinforced concrete upright columns along transverse rows and longitudinal rows, and form a latticed frame structure with the upper ends of the reinforced concrete upright columns; two ends of arc arch bars of which the middles are upwards protruded are vertically fixed on the longitudinal beams of two adjacent longitudinal rows respectively; the arch bars are in the matrix arrangement mode at uniform intervals; a plurality of top draw bars are fixedly connected with top ends of the arch bars of the longitudinal rows in turn; a pest-resistant net is fixedly covered on the outer side except the ground of the frame structure which consists of the reinforced concrete upright columns, the longitudinal beams, the arch bars and the top draw bars; a plurality of elongated top films are fixedly covered on upper sides of the middle sections of the arch bars of the longitudinal rows at set intervals; and the ground under the intervals is provided with a drainage channel which corresponds to the intervals. The pest-resistant rainproof shed has low construction cost, large space, high storm resistance, high vegetable yield and quality and light pesticide pollution, and can be a high efficiency facility with double purposes of a net house and a greenhouse, and a land multi-cropping index is improved.

Description

technical field [0001] The invention relates to a facility for agricultural production, in particular to an insect-proof and rain shelter. Background technique [0002] With the rapid development of facility agriculture, the requirements for facilities are getting higher and higher, especially for facilities with wide application, long service life and low cost. At present, the types of facilities widely used in production in my country are mainly plastic greenhouses and insect-proof net sheds. Among them, plastic greenhouses are mainly bamboo-wood structure plastic greenhouses, single-span steel pipe plastic greenhouses and multi-span steel pipe plastic greenhouses. These facilities have their own characteristics and advantages. limitation: [0003] 1) Bamboo-wood structure plastic greenhouses are composed of moso bamboo plus films and straw curtains for insulation. Generally, the greenhouses are 5-8m wide, 2-3m high at the top, 1-1.2m high at the side, 50-100m long, and th...

Problems solved by technology

The main body is generally made of hot-dip galvanized steel as the main load-bearing structure, and the steel pipe composite truss or independent steel pipe parts are used for the roof, which can resist 8-10 strong winds. , the land utilization rate is over 90%, but the cost is greatly increased;

[0006] 4) Ordinary insect-proof net sheds are relatively simple to build. In the vegetable field, set up a steel pipe or cement column at an interval of about 3m. The height of the column is about 2.2m. The surroundings are buried tightly with soil and fixed with netting wires to prevent strong winds. Vegetable pests can be isolated from the net, and chemical pesticides can be avoided or sprayed less to reduce pesticide pollution of vegetable products. The disadvantage is that it has poor anti-storm ability and cannot be used in winter. , can not achieve annual production, the service life is short, and the maintenance cost is high;

[0007] Plastic greenhouses are mainly used for cultivation in the long seasons of spring, autumn and winter, mainly fruit vegetables. In summer, the use efficiency is low due to the high temperature in the greenhouses; while insect-proof net greenhouses are mainly used for the production of leafy vegetables in summer, but are affected by the weather. The impact is relatively large. In stormy weather, the mechanical damage of the blade is large, and the output and commodity rate are low.
