Road surface milling machine

Abstract

A road surface milling machine comprises a vehicle frame and vehicle wheels, wherein a traction device is arranged at the front part of the vehicle frame; a machine frame is arranged above the vehicle frame, and the front and the rear sides at the bottom of the machine frame are inserted into horizontal sliding slots on the vehicle frame; a machine frame horizontal driving device is arranged between the machine frame and the vehicle frame; an internal combustion engine is arranged on the machine frame, and is connected with a milling device on one side of the vehicle frame via a first belt, a lower belt pulley, a first universal joint, a telescopic transmission shaft and a second universal joint; the milling device on one side of the vehicle frame is fixed on an inclination adjusting device; the inclination adjusting device is connected with a lifting device fixedly connected to the machine frame; the internal combustion engine is connected with a hydraulic pump fixed at the lower part on the rear side of the machine frame through a second belt; a tension belt pulley is arranged between the forward-inclined first belt and the backward-inclined second belt; a tension wheel shaft arm of the tension belt pulley is flexibly connected with the bottom of the machine frame; one end of a pull rod is flexibly connected with the middle part of the tension wheel shaft arm, and the other end of the pull rod is flexibly connected with an operating rod brake handle; and a control device is arranged on one side of the vehicle frame. The road surface milling machine is convenient to operate and low in cost, and has a high efficiency.

Description

Technical field: [0001] The invention relates to a road construction machine, in particular to a small road milling machine used for crushing and filling bad parts of old roads. Background technique: [0002] At present, the milling machines for crushing old roads are all large self-propelled. The milling head is located in the middle of the wheel and can only be lifted up and down, and cannot move left and right. Therefore, it is only suitable for the overall renovation of the road surface and not for the local bad parts. , In particular, it is impossible to mill to the roadside, and the remaining part of the roadside during pavement repair has to be carried out manually, which is labor-intensive, labor-intensive, time-consuming, low in efficiency, and high in cost. Invention content: [0003] The invention provides a small road surface milling machine, which is simple in structure, reasonable in design, easy to operate and use, especially suitable for digging and repairi...
