Full-open type film rolling greenhouse

Abstract

The invention relates to a full-open type film rolling greenhouse. The greenhouse comprises a greenhouse support and an agricultural film covering the greenhouse support, the agricultural film comprises two roll films covering arch bars, and the two sides of each roll film are connected with film rolling rods; the film rolling rods are horizontally placed on the arch rods and perpendicular to the arch rods, and two bidirectional shaft motors are arranged on the left side and the right side of the portion, between the two film rolling rods, on the greenhouse support; each bidirectional shaft motor is arranged at one end of a first telescopic rod which is rotationally connected with a cross beam, two transmission shafts of the bidirectional shaft motors are connected with the film rolling rods through a transmission adjusting mechanism composed of second telescopic rods and universal joints, two arc-shaped racks connected with the greenhouse support are arranged between the two rolling films, and gears meshed with the racks are arranged on the transmission shafts. Under the control of the bidirectional shaft motors, the roll films can be rolled, a greenhouse top can be opened, and the ventilation effect is good so that plants can receive sufficient illumination or sufficient irrigation of rainwater; the rolled films are put down when heat preservation is needed; the operation is convenient, the use is flexible, and the different requirements of the plants are met.

Description

technical field [0001] The invention relates to a greenhouse for agricultural planting, in particular to a fully-open roll film greenhouse. Background technique [0002] The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, the greenhouse is used for potted flower cultivation, fruit tree planting, forest tree seedling cultivation and so on. Greenhouses generally use bamboo and wood poles, cement poles, light steel pipes and other materials as the skeleton, and make upright columns, tie rods, arch rods and pressure rods, and then cover them with plastic film to form an arched greenhouse. Due to technical reasons in existing greenhouses, the top film can only be opened about 1 meter, and the ventilation effect is very poor. In addition, for some greenhouses used for fruit tree planting, sometimes the top film needs to be opened in a large ar...

AI Technical Summary

Problems solved by technology

Due to technical reasons in existing greenhouses, the top film can only be opened about 1 meter, and the ventilation effect is very poor. Moreover, for some greenhouses used for fruit tree planting, sometimes the top film needs to be opened in a large area to facilitate rainwater irrigation to fruit trees, but Current greenhouses cannot meet this demand

At present, although the greenhouse has a good thermal insulation effect, because the top film cannot be opened in a large area according to the needs, there are problems such as poor ventilation, unsatisfactory light, and rainwater cannot be directly used to water the plants.
