Abstract
The present invention relates to a milling cutter shaft, comprising a milling shaft, the middle section of the milling shaft is provided with multiple rows of middle milling tooth assemblies, and the left and right sections of the outer peripheral surface of the milling shaft are respectively provided with a plurality of A left milling tooth assembly and a plurality of right milling tooth assemblies, a plurality of left milling tooth assemblies and a plurality of right milling tooth assemblies are respectively arranged in a reverse helical shape from the middle section of the milling shaft to its two ends, and the outer peripheral surface of the milling shaft There are multiple side milling tooth components on the left and right sides of the ring, and the all-round non-blind zone setting greatly improves the milling effect and milling efficiency. In addition, the installation position of the left tool holder and the right tool holder adopts special specifications of welding templates with pads and positioning pins to achieve precise installation through special techniques, reduce the installation position deviation between the tool holders, and improve the milling effect.
Description
technical field [0001] The invention relates to a milling cutter shaft and a production method thereof, belonging to the technical field of engineering machinery. Background technique [0002] Milling machine is one of the main types of asphalt pavement maintenance construction machinery and one of the main equipment for asphalt concrete road maintenance construction. It is mainly used for excavation and renovation of asphalt concrete surfaces such as highways, urban roads, airports, and freight yards. Among them, the milling device is the working device of the milling machine. The asphalt concrete surface layer of the old pavement is excavated through the milling device, and then the discarded asphalt material after milling is recycled. The foamed asphalt cold recycling technology is used to recycle Asphalt pavement materials and cement-stabilized base materials are recycled to give full play to the "surplus value" of old asphalt mixtures, promote the recycling of old pavem...
