Telescopic loader and telescopic conveyor for loader

Abstract

The invention provides a telescopic scrabbling and loading machine and a telescopic conveying machine for the scrabbling and loading machine, and relates to the field of mining and engineering machinery. The telescopic scrabbling and loading machine comprises a conveying frame, a telescopic mechanism, a conveying belt collecting and releasing device, a supporting wheel frame, a belt tensioning device, a scraper device and a hydraulic oil cylinder. According to the scrabbling and loading machine, the rear size of the conveying machine can be adjusted in a telescopic mode, so that the scrabbling and loading machine can walk conveniently and fast when working in a narrow roadway, and the adjustment requirement of multiple kinds of industrial and mining trucks for the loading length are met at the same time. The problems that the conveying mechanism for the scrabbling and loading machine walks inconveniently in the narrow roadway due to large rear length and the adjustment requirement for the loading length cannot be met due to small rear length are solved. According to the telescopic scrabbling and loading machine and the telescopic conveying machine for the scrabbling and loading machine, hydraulic power of the scrabbling and loading machine is adopted for the telescopic mechanism, the telescopic mechanism is driven by the oil cylinder, a conveying belt is in a tensioned mode all the time when the telescopic mechanism makes telescopic movement, and the telescopic scrabbling and loading machine has the advantages of being convenient to control and operate, compact and reasonable in structural design, low in failure rate, easy and convenient to maintain, low in power consumption, convenient to manipulate, reliable in work, stable in conveying, free of material scattering, continuously efficient, free of deviation of the belt, long in service life and the like.

Description

technical field [0001] The invention relates to mining and tunneling construction equipment in the technical field of mining and engineering machinery, in particular to a telescopic picker and a telescopic conveyor for the picker. Background technique [0002] The belt conveyor mechanism of the existing pick-up machine generally adopts two kinds of fixed or foldable belt conveyors. [0003] For the pick-up machine of the fixed belt conveyor, since the length of the conveyor and the pick-up machine cannot be adjusted, when the rear part of the belt conveyor is longer, the overall size of the whole machine is larger, which is not suitable for the walking transfer of the pick-up machine in narrow lanes. When the rear part of the belt conveyor is short, the overall size of the whole machine is small. Although the loading machine is convenient for walking and transferring, the loading length cannot be increased, which cannot meet the adjustment requirements of various industrial ...

AI Technical Summary

Problems solved by technology

However, when the folding frame is folded, the shape of the whole machine is deformed due to folding, and the belt is loose, so that material transportation and loading cannot be carried out at the same time; at the same time, the belt is loose, and the supporting pulley is easy to fall; in addition, due to structural limitations, the length of the whole machine The range of size shortening is also relatively small
