Crawling tube type feeding device

Abstract

The invention discloses a crawling tube type feeding device and relates to the technical field of material conveying mechanical equipment. The crawling tube type feeding device comprises a crawling tube mechanism and a hopper. The crawling tube mechanism comprises an outer packaging hose and an inner telescopic hose. An inlet in the lower end of the inner telescopic hose communicates with the bottom of the hopper. Electromagnetic driving type crawling units are uniformly distributed on the inner telescopic hose in the length direction. Each electromagnetic driving type crawling unit comprises two electromagnetic coils winding on the outer wall of the inner telescopic hose, and the portion, between every two electromagnetic coils, of the pipe wall of the inner telescopic hose is of an inner corrugated structure capable of telescoping axially. The portion, matched with each inner corrugated structure of the inner telescopic hose, of the pipe wall of the outer packaging hose is further provided with an outer corrugated structure capable of telescoping axially. Driving rings are uniformly distributed on the inner wall of the inner telescopic hose in the axial direction, and the section of each driving ring is in a wedge shape. The crawling tube type feeding device has the beneficial effects that the structure is simple, feeding is easy and flexible, the conveying efficiency is high, and air pressure pumping is not needed.

Description

technical field [0001] The invention relates to the technical field of material conveying mechanical equipment Background technique [0002] For high-altitude concrete pumping operations, people usually use pump trucks, which use air pressure to pump concrete to higher and farther places, but for short-distance and lower-level concrete delivery, it is often necessary to manually use shovels again and again. Adding is time-consuming and labor-intensive, and there will be concrete falling out of the adding process. [0003] At present, there is no device that can replace manual delivery of concrete or other viscous slurries over short distances. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a peristaltic tube feeding device with simple structure, light and flexible feeding, high transmission efficiency and no need for air pressure pumping. [0005] The technical solution adopted by the present invention is: to ...
