Description

Wheel-track dual-purpose multifunctional belt opener

Technical Field

The utility model relates to the technical field of belt opening machines for forests, in particular to a wheel-track dual-purpose multifunctional belt opening machine.

Background

The forest belt cutting machine is mainly used for daily maintenance of working condition construction such as forest fire prevention barrier belts, forest road and river emergency barrier belts and emergency fire prevention channels, is suitable for clearing shrubs, burning lands and forest road opening and trimming of fire prevention barrier belts, and is a modern machine for building a forest fire prevention barrier system.

The belt cutting machine for the forest is based on a crawler excavator, achieves forest cutting by being provided with a belt cutting machine head with a crushing function, and can be provided with a hydraulic shear, a crushing hammer, a hydraulic clamp, a hydraulic push tooth and conventional accessories of a medium excavator to achieve functions of shearing, impact crushing, grabbing and cutting barren grass shrubs and the medium excavator.

At present, the belt opener for forest is mainly in a caterpillar belt form. The advantages are that: the area of contact is big, so muddy, the ground and the road conditions adaptability that go into easily such as wetland are better, also can be competent at the woodland or the abominable place of operating mode, and cross-country ability is strong, and this place that just makes the belt opener can go is more extensive. In addition, the production cost is low and the investment is small. There are however also significant disadvantages: the plate trailer is slow in moving speed and poor in maneuverability, the highest design hourly speed is generally 5-7KM/H, the plate trailer is used for transportation when the plate trailer is used for long-distance movement, a road between mountains is usually narrow, the plate trailer usually needs to be turned around when the plate trailer is driven to a wide area at the end of the road, the plate trailer is quite inconvenient to move, the construction cost is greatly increased, and the construction efficiency is reduced.

The prior non-wheel-track dual-purpose belt opening machine product in the market is similar to wheel-track dual-purpose equipment, and a hydraulic motor is adopted to drive a track to travel; meanwhile, the wheel type travelling mechanism is driven by a transmission mode of an engine, a coupler, a gearbox and a transmission shaft, and a mounting space for transmission components such as the gearbox, the transmission shaft and the like is reserved at the bottom of the frame; the braking of the whole wheel type traveling system is in a pneumatic control mode and is provided with an air pump, an air storage tank, an air source purification processor, a pneumatic control valve, an air cylinder and an axle in a drum brake mode. The disadvantages are that: 1. when the crawler traveling mode is switched, the raised wheel type mechanism needs to be high enough, and the passing performance of the whole machine can meet the requirement, so that the height of a crawler traveling frame (frame) from the ground needs to be high enough, and the spatial arrangement of a gearbox and a transmission shaft can be met, so that the gravity center of the whole machine is raised, and the traveling stability and the working stability are greatly influenced; 2. the space below the crawler walking frame is occupied by the gearbox and the transmission shaft, so that the lower space is limited, and the transmission system is easily damaged due to interference with the ground when the crawler walking frame passes through the ground with a steep slope and a complex road condition; 3. the whole machine crawler mode adopts hydraulic drive and control, and the brake system adopts a pneumatic control structure, so that the system configuration and control are more complicated, and meanwhile, the reliability and the sensitivity of a pneumatic control original piece hardly meet the expected requirements.

In fields such as forestry system, emergency rescue, highway construction, to possessing and having better cross-country ability of traveling in the place that the operating mode is abominable, move simultaneously fast, do not rely on the plate car, complete machine work load is big, construction fill capacity is big, have the wheel-track dual-purpose belt opener demand of great power requirement to hydraulic system comparatively urgent. Therefore, the development of the wheel-track dual-purpose belt opener which has good cross-country capacity, high moving speed and high transition speed (independent of plate car and trailer delivery), has larger working load, meets the hydraulic power requirement of the belt opener and has larger bucket capacity is of great significance.
