Problems solved by technology

The design of the above-mentioned wheeled grilling machine is unreasonable, the parts are seriously damaged, the equipment failure rate is high, the life of the whole machine is short, and there are many safety hazards. The main defects are as follows:
[0003] 1. Due to the large vertical force generated when the digging and feeding mechanism is working, it is easy to cause the slewing bearing seat of the digging slewing mechanism to loosen and break
[0004] 2. Due to the lack of hydraulic buffer valves in the hydraulic system and its operating mechanism, the impact force is relatively large. When the vehicle is moving forward, backward, and emergency stop operations, it is easy to cause damage to the drive motor, front and rear axles
[0005] 3. Because there is no service brake device, there are potential safety hazards when the vehicle is walking
[0006] 4. It adopts a non-foldable (or telescopic) conveyor frame structure. Due to the large overall size of the whole machine, it is inconvenient for construction transitions in narrow roadways
[0007] 5. The conveyor belt is rigidly tensioned without cushioning, and the driving electric drum is prone to stuffy car burning accidents
[0008] 6. The use of rear wheel steering mechanism is not convenient for loading and unloading alignment
[0009] 7. The rear axle suspension chassis structure is adopted, and the vehicle is prone to rollover during the vehicle walking and pick-up work, posing safety hazards
[0010] 8. The axle force point of the current axle suspension mechanism is on the outer casing of the middle part of the axle, which does not meet the requirements for the use of the axle and may easily cause the axle to break
[0011] 9. The size of the hollow part of the current channel steel welded chassis is small, which is not convenient for the arrangement of mechanical and hydraulic components in the chassis

Embodiment Construction

[0030] Such as figure 1 As shown, the present invention integrates a vehicle chassis 1 , an excavation loading mechanism 2 , a conveying and unloading mechanism 3 , an electrical control system 4 , a hydraulic system and its operating mechanism 5 . The motor is driven by an external power supply or a built-in diesel engine as a power source, and electric, hydraulic and mechanical transmissions are used to combine the working mechanism and the running mechanism in the form of a vehicle to form a self-moving pick-and-place machine to realize the walking, steering and braking of the whole machine. . The digging and loading mechanism has functions such as turning, digging, and loading and loading; the conveying and unloading mechanism has functions such as pushing, collecting, receiving, conveying, unloading, lifting, and folding (or telescopic).

[0031] Such as figure 2 , image 3 As shown, the vehicle chassis is mainly composed of chassis frame 7, front axle 8, rear axle 9,...

Abstract

A wheel scrabbling machine relates to the field of mine and engineering machinery and comprises a car chassis, an excavating loading mechanism, a conveying unloading mechanism, an electrical control system, a hydraulic system and an operation mechanism for the hydraulic system; the wheel scrabbling machine adopts a brand new structural design, adopts an external power supply or a self diesel engine as power, and adopts electric, hydraulic and mechanical transmission to realize the continuous hoeing, conveying and loading. The wheel scrabbling machine is compact and reasonable in structure, low in fault rate, simple and convenient in maintenance, flexible in moving and safe and reliable in work and has the characteristics of capability of self walking, stable loading, flexible operation, continuity, efficiency and the like, safety loopholes are reduced and casualty accidents of staff are effectively reduced; the wheel scrabbling machine is suitable for narrow roadways and the construction conditions of an uneven ground, and is mainly suitable for the exploitation and scrabbling operation of a coal mine, a phosphorus ore, an iron mine, a copper mine and a gold mine as well as the collecting and loading of metaling in channel constructions such as a railway, a road, water conservancy and national defense and can also be used in the loading of open-air bulked materials.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wheeled pick-up loader suitable for mining and engineering construction. Background technique [0002] The existing wheel loader, the vehicle chassis mainly adopts the channel steel welded chassis with the front axle fixed, the rear axle suspended, and the rear axle turned, and the wheel drives the walking structure. The whole machine relies on hydraulic brakes and has no driving brake device; the conveying and unloading mechanism Driven by the rear electric drum, non-foldable (or telescopic) conveyor frame structure, the conveyor belt is rigidly tensioned without buffering; the excavating and loading mechanism adopts the upper and lower beam type, and the front side upper and lower hanging type rotary body structure; the hydraulic system and Its operating mechanism does not contain a hydraulic shock valve. The design of the above-mentioned wheeled grilling mach...
