Abstract
The utility model provides a rear brush lifting mechanism which is used for a road cleaning car. The rear brush lifting mechanism comprises a rear brush lifting rod support, a rear brush hydraulic cylinder, a rear brush adjustment rod, a rear brush lifting rod and a rear brush assembly. When the cleaning car is in an empty running state, oil is added to the upper cavity of the rear brush cylinder, a piston rod contracts, and the rear brush moves upwards; the rear brush adjustment rod and the rear brush lifting rod are driven by the rear brush assembly to rotate anticlockwise around the rear brush lifting rod support; the rear brush moves away from the ground, obstacles such as protrusions, concave pitches and speed humps on a road surface can be avoided, the rear brush is not easy to damage, and normal running of a car is guaranteed. When the cleaning car is in a cleaning state, oil is added to the lower cavity of the rear brush hydraulic cylinder, the piston rod extends outwards, the rear brush assembly moves downwards, the rear brush adjustment rod and the rear brush lifting rod are driven by the rear brush assembly to rotate clockwise around the rear brush lifting rod support, the rear brush is grounded, and rubbish on the ground is cleaned to the front side of a main brush through the rear brush. The rear brush lifting mechanism is high in working efficiency.
Description
Technical field
The utility model relates to a kind of elevating mechanism, relates in particular to a kind of back brush elevating mechanism for road sweeper.
Background technology
Road sweeper is a kind of collection road cleaning as one of sanitation equipment, and garbage reclamation and transportation are the new and effective cleaning equipment of one.Be widely used in road-cleanings such as arterial highway, municipal administration, airport, uptown and park.
The cleaning structure of comparative maturity generally is the powerful negative pressure that adopts high pressure positive blower to produce on the market at present, and the rubbish on the road is sucked dustbin, this complex structure, and the power utilization rate is low, and energy consumption is also high.Other has the road-sweeper of wearing single main brush configuration, but the cleaning circuit is single, and pavement garbage can be stressed to the both sides diffusion during cleaning, and sweeping efficiency is low.Also have a kind of road-sweeper to wear the auxiliary main brush cleaning of back brush, but back brush stroke fixes, in the time of can't being implemented in cleaning with the different operating modes of no-load running under switching, practicality is not high, and the back brush damages easily.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to propose a kind of road-sweeper back brush that can solve and is grounded under the different operating modes of cleaning and no-load running and the back brush elevating mechanism that rises.
A kind of back brush elevating mechanism that the utility model provides is used for road sweeper, comprises back brush lifting arm bearing, back brush oil cylinder, back brush adjusting rod, back brush lifting arm and back brush assembly.
Described back brush assembly comprises brush handle and brush.
Be provided with each end that three fixed points connect described back brush oil cylinder, described back brush adjusting rod and described back brush lifting arm respectively from top to bottom on the brush lifting arm bearing of described back, and the other end of the other end of described back brush oil cylinder and described back brush adjusting rod is fixed in the same position of described brush handle by fastening devices.
The other end of described back brush lifting arm also is fixed on the described brush handle and is positioned at the below of described back brush adjusting rod.
Described back brush elevating mechanism is brushed ground connection and the liftoff two states that lifting realizes the back brush by the flexible back that drives of the piston rod of back brush oil cylinder, when road-sweeper is in the cleaning work state, back brush ground connection is brushed front side, high efficiency by the refuse sweeping on brush handle ground, back to the master; When the no-load running of road road-sweeper, back brush is liftoff, increases the gap between vehicle body and the ground, reaches projection, pit, the deceleration of dodging on the road surface and obstacle such as refutes, and the back brush is not fragile, and has guaranteed normally travelling of vehicle.
Description of drawings
Fig. 1 is the structural representation of a kind of back brush elevating mechanism that provides of the utility model.
The drawing reference numeral explanation
1-back brush lifting arm bearing, 2-back brush oil cylinder, 3-back brush adjusting rod, 4-back brush lifting arm, 5-back brush assembly.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
See also Fig. 1, the utility model provides a kind of back brush elevating mechanism, is used for road sweeper, comprises back brush lifting arm bearing 1, back brush oil cylinder 2, back brush adjusting rod 3, back brush lifting arm 4 and back brush assembly 5.
See also Fig. 1, described back brush assembly 5 comprises brush handle 51 and brush 52.
See also Fig. 1, be provided with each end that A, B, three points of C connect described back brush oil cylinder 2, described back brush adjusting rod 3 and described back brush lifting arm 4 respectively on the described back brush lifting arm bearing 1 from top to bottom, and the other end of the other end of described back brush oil cylinder 2 and described back brush adjusting rod 3 and the described back other end of brushing lifting arm is installed on the back respectively and brushes on the assembly on T, P, the H point.
When road-sweeper is in the no-load running state, see also Fig. 1, described back brush oil cylinder 2 epicoeles are oil-filled, piston rod shrinks, back brush assembly 5 is up, and back brush assembly 5 drives back brush adjusting rod 3 and back brush lifting arm 4 rotates counterclockwise around back brush lifting arm bearing, and the back brush is liftoff.
When road-sweeper is in the cleaning state, see also Fig. 1, described back brush oil cylinder 2 cavity of resorptions are oil-filled, piston rod is overhanging, back brush assembly 5 is descending, and back brush assembly 5 drives back brush adjusting rod 3 and back brush lifting arm 4 clockwise rotates around back brush lifting arm bearing, back brush ground connection.
In sum, described back brush elevating mechanism is brushed ground connection and the liftoff two states that lifting realizes main brush by the flexible back that drives of the piston rod of back brush oil cylinder 2, when road-sweeper is in the cleaning work state, back brush ground connection, refuse sweeping by brush handle ground, back is brushed front side, high efficiency to the master; When the no-load running of road road-sweeper, back brush is liftoff, increases the gap between vehicle body and the ground, reaches projection, pit, the deceleration of dodging on the road surface and obstacle such as refutes, and the back brush is not fragile with main brush, and has guaranteed normally travelling of vehicle.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improving the design that will invent and technical scheme, all in protection domain of the present utility model.
