Asphalt barrel opening machine

Abstract

The invention discloses an asphalt barrel opening machine comprising a vertical frame, a flat frame, a first driving device, a second driving device, a cutter holder, a cutter head and a positioning and clamping device. The cutter holder is mounted at the lower end of an output shaft and can rotate under the driving of the second driving device by using the axis of the output shaft as a rotating axis; the cutter head is mounted on the cutter holder through a mounting seat and forms a circular cutting locus under the driving of the cutter holder; the cutter head has the freedom degree of autorotation; and the positioning and clamping device is arranged on the vertical frame part below the flat frame and is used for positioning and clamping an asphalt barrel to be opened. The invention can greatly improve the barrel-opening efficiency and can effectively lessen the influence of scrap iron on asphalt quality.

Description

technical field [0001] The invention relates to a device for opening barrels of asphalt. Background technique [0002] In my country, bulk asphalt is mostly used in the asphalt pavement construction of highway projects in eastern coastal areas and areas with relatively developed land transportation. The transportation method is mainly asphalt tanker with heating device, and the asphalt is in a fluid state. However, in the mid-to-late 1990s in the coastal areas and the current asphalt pavement construction of road projects in remote mountainous areas and areas with underdeveloped land transportation, most of them use barreled solid asphalt, because compared with bulk asphalt, the transportation cost is low, it is easy to store and It is easy to store, easy to transport, and compatible with land and water transportation; because it is a solid, its own loss is small, and the requirements for transportation temperature and time are not affected by weather factors, and the safety...

AI Technical Summary

Problems solved by technology

[0005] 1. The operation method is very primitive and requires a lot of manpower: about 15 to 25 people are needed in the manual operation method of opening the lid;

[0006] 2. Slow speed and low efficiency: When using the manual opening operation method, each person opens a bucket lid in an average of 5-7 minutes, and takes an average of more than 10 minutes to open a bucket lid including the rest time:

[0007] 3. Physical exertion: When using the manual operation method of opening the lid, the workers need to consume a lot of physical strength and need sufficient rest time;

[0008] 4. Expenses of funds: When the operation method of manually opening the lid is used, more funds are required, which is mainly reflected in labor-intensive production process, large investment in wages and other funds, operating tools, safety protection, etc.

[0009] 5. Loud noise: When using the manual operation method of opening the lid, the sound of manual knocking on the steel knife and the noise of the steel knife cutting the lid are very loud, and almost no other sounds can be heard on the job site, causing sound pollution to the surrounding environment. pose a safety hazard to the safety of workers

[0010] 6. Personnel are easy to be injured, and it is difficult to guarantee the safety of personnel at work: workers are easily injured when using the manual operation method of opening the lid

Hitting the steel knife is easy to injure the hands and arms of the workers; steel knives and broken barrel skin fragments are easy to hurt the workers' eyes and scratch the workers' arms; smashed, bruised

[0011] 7. There are iron filings, which have an impact on the quality of raw materials: a lot of iron filings will be produced when the operation method of manually opening the lid is used. These iron filings fall into the asphalt, which will cause wear and blockage of the asphalt pump, and seriously cause production problems. Stagnation, the asphalt pump of the mixing station stops working, which brings great hidden dangers to the subsequent mixing work
