The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

The chassis structure of the existing excavator is fixedly arranged, a chassis system mainly plays a role of supporting the whole excavator, a rotary support is arranged on the top surface of the chassis structure and used for bearing a working device and a cab, and the working device and the cab can rotate. In mechanical engineering, traction refers to the force generated by the interaction between the traction wheel and the ground through the rotation moment generated by the transmission system of the whole vehicle on the wheels. The excavator mainly uses a bucket to excavate materials higher or lower than a bearing area, the working device is positioned at the upper part of the rotary support, the acting force of the bucket is generally vertical, the excavator cannot effectively utilize traction force to realize operation of walking and working, so the excavator generally only carries out fixed-point operation, and a cab rotates together with the working device, namely, the operation range of the excavator is limited within the length radius of the working device.

In order to solve this problem, as shown in fig. 1, 2 and 3, the present embodiment provides a pushing and loading machine, which includes a main frame 1, a cab 2, a ripper 3, a working device 4 and a chassis system 5, wherein the cab 2 is disposed on the main frame 1 and can rotate relative to the main frame, the ripper 3 is rotatably disposed on one side of the main frame 1 and is used for crushing and turning over materials, and the working device 4 is rotatably disposed on the other side of the main frame 1 and is used for shoveling and loading and unloading the crushed and turned materials. The chassis system 5 is provided below the main frame 1, and the chassis system 5 is configured such that the chassis system 5 can move the main frame 1 and the cab 2 while the ripper 3 and/or the working device 4 are/is operated.

In the push loader provided by the embodiment, the cab 2 is arranged on the main frame 1 and can rotate relative to the main frame, so that the push loader has the rotatable cab 2 and a wide working range. Rotate respectively through the both sides at main frame 1 and be provided with agitator 3 and equipment 4, to the harder operating mode of soil stone, utilize agitator 3 earlier with the material breakage with turn the back, later recycle equipment 4 with the material shovel with loading and unloading, under agitator 3 and equipment 4 mutually supporting, can adapt to multiple complicated operating mode, enlarged operation scope and operating mode accommodation, the commonality is stronger.

The excavator and the pushing loader can generate larger traction force to ensure the whole vehicle to walk, but the chassis system 5 and the working device 4 are different, so that the traction force is exerted differently. The push loader that this embodiment provided, equipment 4 and scarifier 3 are fixed in chassis system 5 through main frame 1 on, can utilize the walking traction force of push loader to carry out push transport and the work of turning over, when scarifier 3 and/or equipment 4 work, chassis system 5 can drive main frame 1 and driver's cabin 2 walking, can walk the limit work of walking like the bull-dozer, need not to use with other transport machinery jointly under some specific operating mode, save the time of transfer material, improve the operating efficiency.

Wherein, chassis system 5 includes the track train of two parallel interval settings, specifically, the track train includes drive wheel, thrust wheel, leading wheel, riding wheel, track, overspeed device tensioner and buffer spring, and wherein drive wheel, thrust wheel, leading wheel, riding wheel and track form "four-wheel-in-one" structure, and this chassis system 5 is the same with the chassis system 5 of crawler dozer promptly's theory of operation, avoids easily sinking the car in the wetland operating mode, the condition of abominable operating mode rubber tire easy wear such as mine, has good economic nature. Meanwhile, the crawler wheel system is used as a chassis structure, so that the chassis structure has strong traction force and ground adaptability, and the excavating capability is improved, so that the excavating operation of different layers above the ground surface is completed. Therefore, the pushing machine integrates the functions of a bulldozer, an excavator and a loader into a whole, has powerful functions and has the advantage of a function integration body.

Alternatively, the two crawler wheel systems are connected to the main frame 1 via a balance beam, which serves as an intermediate link. Preferably, the balance beams are connected by adopting a floating structure, so that the functions of buffering and vibration reduction are achieved, and the impact force of the chassis system 5 in the walking process can be absorbed.

It can be understood that the track is composed of an annular structure formed by connecting a plurality of track shoes end to end, and compared with the track shoes of the excavator, the track shoes of the pusher are wider, so that the structural strength of the whole track wheel train is improved, and the stability is good.

The chassis system 5 can drive the main frame 1 and the cab 2 to walk while the scarifier 3 and/or the working device 4 work. In order to ensure that the working processes of the chassis system 5, the ripper 3 and the working device 4 are not interfered with each other, as shown in fig. 4, the pushing and loading machine further comprises a first hydraulic system and a second hydraulic system, wherein the first hydraulic system is communicated with the chassis system 5 and is used for controlling the chassis system 5 to walk.

It can be understood that the number of the traveling pumps 7 and the traveling motors 8 is two, and the two traveling pumps 7 and the traveling motors 8 respectively corresponding to the two traveling pumps form two closed circuits which respectively control the traveling of the two crawler belt trains. By adopting a hydrostatic transmission mode of double pumps and double motors, the steering function of the whole machine in situ can be realized, and the steering mechanism has good maneuverability and traction performance.

Initially, a position signal of the electric control handle 9 is acquired, and the drive controller 11 receives the position signal and outputs an initial displacement signal of the travel pump 7 and an initial displacement signal of the travel motor 8.

Meanwhile, the engine controller 10 obtains signals such as an actual rotating speed, an actual torque and an actual driving voltage of the engine 6, and transmits the signals to the driving controller 11, the driving controller 11 calculates a difference between an actual torque corresponding to a current working position of the engine 6 and a preset torque corresponding to a preset working position, calculates a displacement signal required to be adjusted by the traveling pump 7 and a displacement signal required to be adjusted by the traveling motor 8 according to the torque difference, and outputs the displacement signals required to be adjusted to the traveling pump 7 and the traveling motor 8, respectively, thereby realizing displacement control of the traveling pump 7 and the traveling motor 8. It is understood that the drive controller 11 implements displacement control of the traveling pump 7 and the traveling motor 8 by controlling the swash plates of the traveling pump 7 and the traveling motor 8, respectively.

It should be noted that the working principle of the first hydraulic system is consistent with that of the full hydraulic bulldozer, the traveling pump 7 is adopted for stepless speed change within a limit range, the electric control handle 9, the driving controller 11 and corresponding load feedback signals control the traveling direction and speed of the chassis system 5, and the complete machine is controlled to brake through the brake pedal, so that the chassis system 5 can realize in-situ steering, the complete machine has strong flexibility, can adapt to severe mine working conditions, has low ground pressure, can give full play to the traction force of the complete machine, realizes the rapid transportation of materials, and ensures that the push loader has higher operating efficiency and economic benefit.
