Vegetable greenhouse plastic film laying device

Abstract

The invention discloses a vegetable greenhouse plastic film laying device which comprises an arrangement block. An arrangement cavity is formed in the arrangement block, a film cutting mechanism is arranged in the arrangement cavity, the film cutting mechanism comprises a rotating shaft, the rotating shaft is rotationally arranged in the arrangement cavity, and a film rolling wheel is fixedly arranged on the rotating shaft; and a plastic film is wound around the film winding wheel, a cutting sliding groove with a downward opening is formed in the front side of the inner wall of the upper sideof the arrangement cavity, and a cutting sliding block is arranged in the cutting sliding groove in a sliding manner. According to the vegetable greenhouse plastic film laying device, the vegetable greenhouse top paving and installing work can be automatically completed; the plastic film is clamped and supported to be open through a plurality of clamping mechanisms, so that the mechanisms drive the plastic film to completely cover a greenhouse frame, the clamping mechanisms are driven by a motor to descend and get close to the greenhouse frame at the same time, and the film on the greenhouse frame can be laid more tightly; and in addition, the machine automatically fixes the plastic film and the greenhouse frame through iron sheets with good shaping performance.

Description

technical field [0001] The invention relates to the field of film conveying, in particular to a plastic film laying device for vegetable greenhouses. Background technique [0002] At present, in our country, the technology of using vegetable greenhouses to grow vegetables has been very popular in various places. Greenhouse planting can more effectively manage the cultivation of various crops, improve the prevention of diseases and insect pests and the impact of the weather, and increase the unit yield of crops. At the same time, through the temperature of the greenhouse Humidity and other controls can grow more abundant crops in different regions. Existing greenhouses usually adopt the structure of steel frame arched to support the plastic film. Since the agricultural greenhouse is placed outdoors for a long time, it must face the environment of wind and rain. Over time, the plastic roof film must be replaced, especially in harsh conditions. The weather is more difficult to...

Problems solved by technology

Existing greenhouses usually adopt the structure of steel frame arched to support the plastic film. Since the agricultural greenhouse is placed outdoors for a long time, it must face the environment of wind and rain. Over time, the plastic roof film must be replaced, especially in harsh conditions. The weather is more difficult to guarantee, but the laying of the plastic roof film is very cumbersome, and currently no machine can complete the job
