Foldable bulk material lifting device

Abstract

The invention discloses a foldable bulk material lifting device, which comprises a material lifting main body section and a material lifting folding section, wherein walking support legs are arrangedat the bottom of the material lifting main body section, and the top of the material lifting main body section is hinged to the bottom of the material lifting folding section; a slideway is arranged at the hinge of the material lifting main body section and the material lifting folding section, a rotary shaft is arranged on the slideway, and a corner of the bottom of the material lifting folding section can rotate between a horizontal position and an inclined angle of the material lifting main body section along the rotary shaft on the slideway; a folding oil cylinder is also formed between the material lifting main body section and the material lifting folding section, the end of a folding oil cylinder body is hinged on the material lifting main body section, the end of a cylinder rod ofthe folding oil cylinder is hinged to the material lifting folding section. The invention provides the foldable bulk material lifting device, the device is folded in a transportation state, and can bechanged to be straight to work during working, thereby not only realizing that the whole transportation of a flatbed truck is not super high, but also realizing that the material lifting device can be long and can convey bulk material to a higher position during working.

Description

technical field [0001] The invention relates to an accessory device used in road surface maintenance equipment, in particular to a foldable material lifting device used for lifting bulk materials in asphalt pavement regeneration. Background technique [0002] At present, there are two types of transportation methods for hot-in-place recycling equipment for pavement materials. One is the self-propelled mode, which is pulled by a tractor and directly walks on the road. After this type of equipment is produced, it needs to be certified on the road. The other is the flatbed truck transportation method. After this kind of equipment is put on the flatbed truck, due to the limited overall height transportation, the equipment has a certain height limit in design. [0003] The material lifting device is a device that lifts the bulk material to a certain height, which creates a design contradiction with the overall height limit. The existing lifting device is always in an upright ...

AI Technical Summary

Problems solved by technology

The existing lifting device is always in an upright state and can only be placed on the equipment in this way. There are height restrictions during transportation, which increases the difficulty of transportation and transportation costs.
