Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical operation tools for construction, highway, forestry, agriculture and grassland engineering, and specifically relates to a multifunctional toothed tool support. Background Technology

[0002] Road milling machines are one of the main types of machinery used in asphalt pavement maintenance and construction, and one of the main pieces of equipment used in asphalt concrete pavement maintenance and construction. They are mainly used for excavation and renovation of asphalt concrete pavement in highways, urban roads, airports, freight yards, etc. They can also be used to remove defects such as road bulges, oil waves, textures, and ruts. In addition, they can be used to excavate road potholes and trenches, as well as roughen cement pavements and mill out misalignments.

[0003] Milling the damaged old pavement with a road milling machine and then laying a new surface layer is the most economical and modern maintenance method. It is widely used in urban municipal roads and highway maintenance projects because of its high work efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and the ability to directly recycle the milled old material.

[0004] A forestry mower is a heavy-duty machine that clears land by cutting, grinding, and removing vegetation. This process is often referred to as "forestry mowing" or "forestry mulching." It is commonly used to manage woody vegetation and gravel because it is a very efficient and fast method of clearing land. Traditional methods of hand-cutting or burning were once used to clear land, but these were very slow and time-consuming. Bulldozers were sometimes used for this process, but heavy bulldozers leave the soil bare and susceptible to erosion.

[0005] Therefore, a multifunctional dental fixture support is urgently needed. Utility Model Content
