Background technology
Along with being open to the traffic in a large number of China's speedway and urban road, the task kept a public place clean in road surface is more and more arduous, therefore state various places are dropped into a large amount of funds and have been purchased the higher road surface cleaning equipment of many automaticities, widely using of these cleaning equipments, drastically increase effect and the efficiency of road cleaning, also mitigate the labour intensity of street cleaner simultaneously, and ensure the personal safety of street cleaner.
Road road-sweeper is modal one in the cleaning equipment of road surface, integrate road cleaning, garbage reclamation and transport, in use, first by telescopic hydraulic bar, the plate rail that disc brush and sweep-up pipe are housed to be dropped to proper height, then start disc brush to drive and road-cleaning is carried out in dust suction driving, this mode ideally can well complete road cleaning in evenness of road surface; But the road surface that well can reach formation state in China is relatively less, meeting unavoidably can not cause road surface subsidence or roll the shape road surface, corrugated of swaging one-tenth in automobile passes through process, there is the sordid problem of cleaning with the disc brush mechanism of existing this road sweeper in take the altitude in the case, affect by ground is irregular simultaneously, occasionally have in the process that road cleaner runs and occur with plate rail impingement phenomenon, because plate rail and oil cylinder are for being rigidly connected, there is the flimsy problem of oil cylinder.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of and can be applied in roughness pavement and can improve the pavement cleaning vehicle of cleaning capacity, can overcome the deficiencies in the prior art.
The technical solution of the utility model to improve the pavement cleaning vehicle of cleaning capacity, it comprises pavement cleaning vehicle, plate rail is provided with in the bottom of road sweeper, disc brush is connected with in the below of plate rail, brush, by fluid motor-driven, is connected with bracing frame by pull bar above plate rail, is connected with hoist cylinder at bracing frame, pull bar between plate rail and bracing frame is socketed with spring, plate rail is provided with vibration motor.
The above-mentioned pavement cleaning vehicle that can improve cleaning capacity is, the height of vibration motor is less than the minimal compression distance of spring.
The aforesaid pavement cleaning vehicle that can improve cleaning capacity is, the quantity of pull bar is four, lays respectively at the corner of bracing frame, and vibration motor is between four pull bars.
Compared with the prior art, the utility model by being connected with bracing frame by pull bar above plate rail, bracing frame connects hoist cylinder, pull bar between plate rail and bracing frame is socketed with spring, plate rail is provided with vibration motor, the plate rail of existing pavement cleaning vehicle so just can be made to become from being rigidly connected the variable elastic connection way that moves up and down, under the drive of vibration motor; Thus make plate rail of the present utility model and on disc brush can move up and down, have the following advantages in traveling process like this:
1, disc brush can make the stressed increasing in above ground portion region in the process of vibrations rotation, can improve cleaning effect;
2, disc brush can be swept into the recessed road surface of normal purging zone in the process of vibrations rotation, improves cleaning effect.
3, plate rail adopts elasticity to connect, when run into backing or stressed suddenly can reduce the injury of external force to plate rail, reduce the infringement to oil cylinder and hydraulic motor.
4, because road sweeper can to disc brush place water spray in cleaning process, disc brush, when cleaning, it will inevitably adhere to a lot of mud, impact cleaning effect, and the mud of adhesion can shake by vibrations cleaning process, improves cleaning effect further.
5, being provided with the power decomposition plate tilted at the bottom of car in the side in the vehicle operating direction of plate rail, just horizontal force can being decomposed when running into shock like this, make it along the operation of camber of spring direction, guarantee spring application life.
Embodiment 1. as shown in Figure 1, plate rail 2 is provided with in the bottom of road sweeper 1, disc brush 3 is connected with in the below of plate rail 2, brush 3 is driven by hydraulic motor 4, bracing frame 6 is connected with by pull bar 5 above plate rail 2, bracing frame 6 is connected with hoist cylinder 7, pull bar 5 between plate rail 2 and bracing frame 6 is socketed with spring 8, plate rail 2 is provided with vibration motor 9, the height of vibration motor 9 is less than the minimal compression distance of spring 8, the quantity of pull bar 5 is four, lays respectively at the corner of bracing frame 6, and vibration motor 9 is between four pull bars 5.Being provided with the power decomposition plate 10 tilted at the bottom of car in the side in the vehicle operating direction of plate rail 2, just horizontal force can being decomposed when running into shock like this, make it along the operation of camber of spring direction, guarantee spring application life.
