Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, the road milling machine of this embodiment includes a main frame 1, a front crawler 2, a milling drum, a rear crawler 4, a discharge belt conveyor 5, a drive unit (not labeled), and a cab (not labeled) . figure 2 The direction of the arrow A in the middle is the forward direction of the road milling machine. The front and rear in the following descriptions are relative to the arrow A. When the forward direction changes, the front and rear also change relatively. For ease of description, the length direction of the road milling machine body (parallel to the road milling machine traveling direction) is defined as the longitudinal direction, and the width direction of the road milling machine body is defined as the transverse direction.

[0024] The drive unit and the driver's cab are installed on the main frame 1, and the drive unit provides power for the road milling machine and its components. The drive unit in this embodimen...

Embodiment 2

[0029] Such as Figure 10 As shown, a motor 8 for driving the front milling drum 3a to rotate is installed on the top plate of the front cover body 7, and a planetary reducer 9' fixed to the milling drum cylinder is arranged in one end of the front milling drum 3a, and the transmission box 10 is fixed to the front cover body 7, the output shaft of the motor 8 is connected with the input shaft of the transmission box 10, and the output shaft of the transmission box 10 is connected with the input shaft of the planetary reducer 9', so that the power of the motor 8 is transmitted to the front milling machine Planing drum 3a. The structure of the side milling drum 3b is the same as that of the front milling drum 3a.

Embodiment 3

[0031] Such as Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the motor 8 and the reducer 9 installed above the cover body are arranged non-coaxially, the motor 8 and the reducer 9 are arranged in front and back, and the output shaft of the motor 8 Link to each other with the input shaft of speed reducer 9 by belt. The structure of the side milling drum 3b is the same as that of the front milling drum 3a.

[0032] Also refer to Figure 12 In this embodiment, a reinforcing partition 6a is arranged inside the containing groove 6, and the reinforcing partition 6a divides the containing groove 6 into two containing spaces, and at the same time increases the strength of the main frame.

Abstract

The invention provides a milling machine for a wide-width roadbed. The milling machine comprises a host rack, a front travelling device, a rear travelling device, a driving unit, a cab, a milling roller, and a discharging belt machine, wherein the front travelling device and the rear travelling device are used for supporting the host rack; the driving unit and the cab are mounted on the host rack; the milling roller is mounted below the host rack and is located between the front travelling device and the rear travelling device; and the discharging belt machine is arranged at the front part of the host rack. The discharging belt machine is used for discharging materials milled and cut by the milling roller; a vertical cross section of the host rack above the milling roller is door-shaped and forms an upward containing groove; the milling roller is arranged in a cover body with an opening at the bottom; an opening is arranged on a front cover plate of the cover body; a feeding end of the discharging belt machine is arranged at the opening; a motor for driving the front milling roller to rotate is arranged above the cover; an output shaft of the motor is connected with an input shaft of the milling roller through a transmission piece; and the motor is located in the containing groove above the milling roller.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a wide-width road surface milling machine mainly used for repairing high-grade road surfaces such as expressways. Background technique [0002] Road surface milling machine is one of the main types of road surface maintenance construction machinery, mainly used for clearing sacks, oil waves, textures, ruts, etc. on asphalt concrete surfaces such as highways and urban roads. Milling the damaged old pavement with a road milling machine, and then laying a new pavement is an economical and modern maintenance method, because of its high work efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and The old materials can be recycled directly, so it is widely used in urban municipal roads and expressway maintenance projects. [0003] A general road milling machine is composed of an eng...
