Description

All-hydraulic bucket wheel excavates, broken, reprinting combine coal mining unit

Technical field

The invention belongs to heavy-duty machinery, particularly a kind of all-hydraulic bucket wheel excavation, broken, reprinting combine coal mining unit.

Background technology

At present, countries in the world produce and the excavation machinery of application is all by Motor Drive, and electric energy is converted to mechanical energy; This form is a kind of traditional method of routine, and the weak point of this method is that it will be subject to the restriction of environment and condition, if do not have power supply, or at a distance of the far field, wilderness of power supply, severe working condition, just cannot obtain the performance of advanced machinery benefit, can only adopt original operating type, such as using power shovel, excavate material and by modes such as automobile, trains, transport again, cause the waste of a large amount of manpower and materials, and it is high to consume energy, mechanization degree is low, and production efficiency is low.

In coal production, along with scientific and technical development, manufacturing technique method has also had large increase in the open, has changed and has opened the means of transportation that side slope adopts electric locomotive in the past, and engineering quantity and maintenance are very large.Due to the appearance of heavy-load automobile, present opencut,, not selecting the means of transportation of electric locomotive, uses automobile instead and reaches work plane, by the power shovel direct entrucking that mines for coal, transports ground to.Although it is very large to improve, and is still depositing deficiency, such as drilling and blasting to coal seam, elder generation collapses coal loose, is excavating; Very short due to excavator loading distance, automobile must reach work plane, need to constantly repair the roads, and production link as much and complexity powered and also will be followed up, operation is in the same old way many, manually many, and the cost of coal is very high.

A kind of " the bucket wheel excavator patent of invention " of our application, the patent No. is ZL201110033782.7 and " hydraulic system of bucket-wheel excavator " utility model patent, the patent No. is ZL201120229523.5, has solved above-mentioned technical deficiency, but can't adapt to the needs of different condition, we find in practice, to the hard coal seam of ature of coal, when the digging, the lumpiness of coal is too large, is unfavorable for the conveying of elevating conveyor, must increase broken processing link, product can not settle at one go; In lorry loading link, automobile erect-position can only be in a fixing place, a chassis dress, the serious like this performance that affects complete machine production efficiency in addition.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of and can give full play to rapidly and efficiently advantage of excavator, reduce special broken production link, the all-hydraulic bucket wheel that can load fast continuously excavates, broken, reprinting combine coal mining unit.
