Abstract

The invention discloses a lifting platform for a greenhouse. The lifting platform for the greenhouse comprises a shear fork type lifting mechanism. The shear fork type lifting mechanism comprises an inner shear fork frame and an outer shear fork frame. Bearings are installed on the two sides of the upper end of the inner shear fork frame, and bearings are installed on the two sides of the lower end of the outer shear fork frame. Each bearing comprises an inner ring, an outer ring, rolling balls, a pair of sealing end covers, first sealing parts and second sealing parts. A pair of limiting sleeves are arranged on the outer wall of each inner ring, and a pair of limiting sleeves are arranged on the outer wall of each outer ring. The sealing end covers are arranged between the corresponding end faces of the inner rings and the corresponding end faces of the outer rings. The first sealing parts are arranged in first gaps which are formed between the outer sides of the corresponding sealingend covers and the inner rings/the outer rings. The second sealing parts are arranged in second gaps which are formed between the inner sides of the corresponding sealing end covers and the inner rings/the outer rings. Due to the fact that the structure is adopted, the bearings of the lifting platform for the greenhouse have the good sealing performance, the dust can be prevented from entering the device, and the phenomenon that the lifting operation of the shear fork type lifting mechanism can be affected is avoided.

Description

technical field [0001] The invention belongs to the field of mechanical operation equipment for vegetable planting in modern greenhouses, and in particular relates to a lifting platform for greenhouses. Background technique [0002] Greenhouse cultivation refers to a method of cultivation of horticultural crops. Use warming, heating, light transmission and other equipment (such as cold beds, hotbeds, greenhouses, etc.) and corresponding technical measures to protect heat-loving plants from cold, survive the winter or promote growth and early flowering and fruiting. At present, there are mainly two types of greenhouses used for the production of potted flowers in China: solar greenhouses and modern greenhouses. Sunlight-type greenhouses are widely used in China, especially in the north where there is sufficient light energy. Single-roof forms are commonly used. There is only one light-incoming surface facing south. The structure is simple, and it receives more sunlight in wi...
