Description

Technical Field

[0001] The utility model belongs to the technical field of milling machines, and specifically relates to a novel electric self-propelled milling machine. Background Art

[0002] Pavement milling machine is one of the main types of asphalt pavement maintenance and construction machinery, and one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for excavation and renovation of asphalt concrete surface layers in highways, urban roads, airports, cargo yards, etc. It can also be used to remove road bumps, oil waves, reticulation, rutting and other defects. It can also be used to excavate road potholes and grooves, as well as roughening cement pavement and milling the surface layer misalignment. Existing milling machines cannot switch the mobile mode freely. For some difficult construction roads that require manual construction by operators, milling machines cannot efficiently switch between manual and automatic modes, resulting in a significant reduction in pavement construction efficiency. This phenomenon has become a problem that needs to be solved urgently by people in this field. Utility Model Content

[0003] The purpose of the utility model is to provide a novel electric self-propelled milling machine to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a new electric self-propelled milling machine, including a front wheel mechanism, a milling mechanism, a transmission mechanism, a rear frame mechanism and a traveling mechanism; the front wheel mechanism includes a high-hardness hardened iron wheel, a shaft, a bearing and a bracket.

[0005] Preferably, the front wheel mechanism is arranged at the front end of the milling mechanism to play the role of walking and steering, and the transmission mechanism is arranged above the milling mechanism and consists of a 2-stage high-speed motor, a pulley and an adjustment mechanism.

[0006] Preferably, the rear frame mechanism is formed by integrally bending and welding high-strength carbon steel, is strong and durable, and is evenly fixed with four high-grade bolts on the rear side of the milling mechanism.

[0007] Preferably, the adjustment mechanism is provided with manual and automatic travel functions, and the current function is locked after the adjustment is completed.

[0008] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model solves the problem that the movement of the milling machine cannot be switched manually or automatically in the current market. After the high-power motor is powered on, the wheels at both ends of the high-strength walking spindle are commanded to move forward or backward through the switch, solving the problem of empty push self-locking of the large-speed ratio driving reducer, controlling the walking speed and turning, overcoming the defects of the traditional milling machine, eliminating the potential safety hazards, and at the same time, having stronger power, better milling effect, greatly reducing the failure rate, and greatly improving the work efficiency;

[0009] The operator drives the milling machine forward or backward through the control switch, and the milling mechanism starts to construct the asphalt or cement road surface. During the construction process, the knob switch controls the secondary high-speed motor, and transmits power to the milling machine through the belt, so that the milling machine runs at high speed. The knob switch is equipped with forward and reverse functions, which can freely run the milling machine forward or reverse according to the actual working conditions. The walking mechanism is equipped with a large-speed ratio turbine reducer and a high-power motor. A through shaft passes through the middle of the turbine reducer, and tires are fixed at both ends of the shaft to rotate. The milling machine is automatically driven to move through the switch, which is convenient for rapid construction of the road surface and improves construction efficiency. At the same time, for parts that are difficult to construct, the operator can use the manual automatic switching mechanism to move;

[0010] The milling mechanism is short in front and long in the back, and the turning function can be easily achieved by pressing down the handrail mechanism on the lever principle. The rear auxiliary small wheel can be lifted off the ground or touch the ground by shaking the handle on the adjustment mechanism (at this time, the arched driving wheel is off the ground), realizing the clutch function and solving the self-locking problem of the large speed ratio reduction drive mechanism. The operator can manually push the milling machine forward and backward to facilitate better construction transfer and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

This device solves the problem that the milling machine cannot be switched manually or automatically in the current market.
