Sandblaster with improved working efficiency

Abstract

The invention relates to a sandblasting tool, in particular to a sandblaster with the improved working efficiency. The sandblaster is used for filling a top pipe and heating pipes with fixtures when heat network pipes are laid with the non-excavation technology, and is mainly formed by an air inlet pipe, a sand storage pipe and a sand outlet pipe, wherein the air inlet pipe, the sand storage pipe and the sand outlet pipe are sequentially connected through flanges. A sand inlet hopper communicated with the sand storage pipe is perpendicularly and fixedly connected with the upper portion of the sand storage pipe, landing legs are fixedly connected to the lower portion of the sand storage pipe, the sand outlet pipe is connected with a sand outlet rubber pipe, the sand outlet rubber pipe is arranged on a pipe winding disc driven by a pipe winding motor in a wound mode, and a feeding transferring mechanism driven by a feeding motor is connected to the sand inlet hopper. Due to the design that the sand outlet pipe is connected with the sand outlet rubber pipe, and the sand outlet rubber pipe is arranged on the pipe winding disc driven by the pipe winding motor in the wound mode, the pipe winding disc is driven by the pipe winding motor to carry out automatic pipe winding, working efficiency is improved, the speed is constant and adjustable, and product quality is improved; in addition, feeding is carried out on the sand inlet hopper through the feeding transferring mechanism driven by the feeding motor, labor intensity is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a sandblasting tool, in particular to a sandblasting device for improving work efficiency, which is applied to pipe jacking and heat pipeline filling fixtures in laying heat network pipelines by adopting non-excavation technology. Background technique [0002] The heat network is composed of heat transmission trunk lines, heat distribution trunk lines, and branch lines. The heat transmission main line is drawn from the heat source, and generally does not connect to the branch line; the heat distribution main line is directly connected to the heat transmission main line or directly from the heat source, and heat is supplied to the user through the heat distribution branch line. [0003] The layout of the heating network is mainly determined according to the distribution of urban heat load, the status quo of the block, the development plan, and the geological and topographical conditions, etc., and is generally arranged in a bran...

Problems solved by technology

However, this kind of equipment needs to be manually collected when the sand and rubber pipe is withdrawn while blowing the sand. Due to the manual control of the collection speed, the work efficiency is low and the product quality is poor.

The existing method requires three people to continuously shovel sand into the hopper to meet the speed of sandblasting, which is labor-intensive and low-efficiency
