Asphalt milling and planing material distributing machine for asphalt plant mix hot recycling

Abstract

The invention provides an asphalt milling and planing material distributing machine for asphalt plant mix hot recycling. The asphalt milling and planing material distributing machine for asphalt plant mix hot recycling can effectively solve the problem of material blocking and is accurate in feeding and weighing. The asphalt milling and planing material distributing machine for asphalt plant mix hot recycling comprises a steel structure body, one or more storage bins, belt weighers, vibrating devices and pneumatic arch breaking devices. A material baffle is arranged at the top of the steel structure body. The storage bins are fixed to the steel structure body. Screens are installed at feeding ports of the storage bins. The belt weighers are arranged at discharging ports of the storage bins. The vibrating devices are arranged on the two sides of the storage bins respectively and located below the screens, each vibrating device comprises a vibrating motor and vibrating beams, the vibrating motors are fixed to the storage bins, and the vibrating beams penetrate through the storage bins and are connected with the vibrating motors. Each pneumatic arch breaking device comprises a main pipeline and a pneumatic arch nozzle, the main pipelines are installed on the steel structure body and located above the vibrating beams, and the pneumatic arch nozzles are arranged on the inner walls of the storage bins.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an asphalt plant mixed hot recycled asphalt milling material batching machine. Background technique [0002] Plant-mixed heat regeneration is to recycle the old asphalt concrete pavement surface layer through excavation or milling to the mixing plant, carry out pretreatment such as crushing and screening as required, and then add a certain proportion of new aggregate and new asphalt , regeneration agent, etc., after heating and mixing with special recycled asphalt concrete mixing equipment, transport it to the construction site, and pave to form a new asphalt concrete pavement structure layer with certain road performance. [0003] The factory-mixed hot recycled asphalt milling material contains a large amount of asphalt particles, stones, fiber particles and other materials, and it is easy to bond when stored at room temperature, especially after it is ...

AI Technical Summary

Problems solved by technology

[0003] The factory-mixed hot recycled asphalt milling material contains a large amount of asphalt particles, stones, fiber particles and other materials, and it is easy to bond when stored at room temperature, especially after it is added to the batching bin, it will be bonded soon. Not easy to feed smoothly

[0004] At present, there are the following problems in the process of using the factory-mixed heat regeneration batching machine. First, the common factory-mixed heat regeneration mixing station batching machine has two storage bins. From the perspective of the addition of recycled materials, due to the recycled milling material The binning span is large, and it is difficult for the two batching hoppers to meet the mix ratio required by the road surface; secondly, the batching machine of the traditional factory mixing hot regeneration mixing station does not have a metering scale, and the milling material cannot be added according to the ratio, which seriously affects the quality of the recycled material and the old Thirdly, due to the high cohesiveness of recycled milling and planing materials, the storage bin is prone to material blocking, and poor feeding will affect the inaccurate gradation of the finished asphalt mixture and affect the overall production progress.
