Fixing device capable of preventing snow cover accumulation for agricultural greenhouse

Abstract

The invention discloses a fixing device capable of preventing snow cover accumulation for an agricultural greenhouse. The fixing device comprises a fixing column, a mounting assembly and a fixing assembly, wherein a cross rod is mounted at an inner side above the fixing column, wedges are fixed to the two ends of the cross rod, an arch bar is mounted at the top end of the fixing column, a fixing ring is arranged at the outer side of the arch bar, a fixing rod is fixed below the fixing ring, the fixing rod and the cross rod are of bolted connection, the mounting assembly is arranged below the fixing column, a reinforcing rod is mounted at the outer side of the fixing column, the fixing assembly is arranged at a joint of the arch bar and the fixing column, and a snow clearing assembly is fixed to one side of the arch bar. According to the fixing device capable of preventing snow cover accumulation for agricultural greenhouse, two sets of pusher plates are arranged, and a snow clearing shovel is conveniently pushed to carry out snow clearing through simultaneous relative running under the action of an electric push rod, so that snow drifts can freely fall along arc-shaped faces of greenhouse plastic films after being loosened, and the efficiency of snow clearing is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a fixing device for preventing snow accumulation in agricultural greenhouses. Background technique [0002] Agricultural greenhouses are thermal insulation greenhouses used to grow fruits and vegetables and other crops. The greenhouses are made of bamboo poles, pipes and other materials as skeletons, and finally covered with plastic films to form an arched space, which is conducive to planting off-season vegetables and raising them. For the survival rate of fruits and vegetables, agricultural greenhouses are widely used in my country, and effective fixing devices are needed in the process of installing and fixing greenhouses. [0003] The bottom installation structure of the existing agricultural greenhouse fixing device is relatively simple, which is easy to cause the greenhouse support to topple over. The fixing structure between the arch rod and the fixed colum...
