Chamber is picked up in the suction of mouth, and the opening that chamber bottom is picked up in suction is suction inlet, and front apron is usually elastic baffle and intracavitary side is picked up in lower end to suction
Tilting, suction tube is used to connect suction and pick up chamber and dustbin, under the swabbing action of blower fan, the rubbish that is gathered together by brush and nozzle
Picked up at front apron into suction in chamber and enter dustbin via suction tube, realize the cleaning of road pavement rubbish.
The attachment structure of suction nozzle 7 and vehicle frame 10 as shown in Fig. 2 connected between suction nozzle 7 and vehicle frame 10 by four telescoping cylinders,
Telescoping cylinder is specially telescopic cylinder 6, and the cylinder body of telescopic cylinder 6 is connected on vehicle frame 10, and the piston rod of telescopic cylinder 6 is connected in suction
On mouth 7, the tie point of telescopic cylinder 6 and suction nozzle 7 is substantially at four corner positions of suction nozzle 7, so improves suction nozzle 7 and car
The stability that frame 10 connects.Telescopic cylinder 6 is double-acting cylinder, could so realize the decentralization of suction nozzle 7 and lift.When flexible
Cylinder 6 is under the control of its atmospheric control during elongation downwards, and the piston rod of telescopic cylinder 6 moves down with suction nozzle 7, directly
Reach rational gap to suction nozzle 7 and ground；When telescopic cylinder 6 is retracted upwards under the control of its atmospheric control, stretch
The piston rod of contracting cylinder 6 can move upwards with suction nozzle 7, can so increase the gap between suction nozzle 7 and ground, if will
When suction nozzle 7 lifts, atmospheric control is set to continue to control the piston rod of telescopic cylinder 6 to move upwards, until needed for reaching and lifting
Requirement for height, realize the lift action of suction nozzle 7.
The atmospheric control of telescopic cylinder 6 is as shown in figure 3, including magnetic valve 4 and source of the gas, source of the gas specifically uses air accumulator
1, separating switch 2 is provided between air accumulator 1 and magnetic valve 4, is divided for the moisture in the gas to being flowed out from air accumulator 1
From avoiding the moisture in gas from causing to damage to pneumatic element.It is also connected with pipeline between separating switch 2 and magnetic valve 4
There is pressure warner 8, for being monitored early warning to the air pressure in gas circuit, can be played when the hypertonia in gas circuit pre-
Alert effect, prevent the hypertonia in gas circuit from causing to damage to the pneumatic element in gas circuit.Magnetic valve 4 is specially five two logical
Valve, five two-way valves have an air inlet, two working holes and exhaust outlet corresponding with two working holes, magnetic valve 4
One in two working holes is connected by pipeline with the rodless cavity of telescopic cylinder 6, and another working hole passes through pipeline and flexible gas
The rod chamber connection of cylinder 6.The second pressure regulator valve 5, electromagnetism are provided with the pipeline that magnetic valve 4 connects with the rodless cavity of telescopic cylinder 6
The pipeline that valve 4 connects with the rod chamber of telescopic cylinder 6 is provided with the first pressure regulator valve 3, and two pressure regulator valves can adjust telescopic cylinder 6
The admission pressure of corresponding chamber, so as to accurately control the action of telescopic cylinder 6.
The distance detector of the terrain clearance for detecting suction nozzle 7 is additionally provided with suction nozzle 7, atmospheric control also includes using
In control magnetic valve 4 and the controller of two pressure regulation valve events, distance detector is connected by circuit with controller signals, and is controlled
Device processed is connected further through signal line with magnetic valve 4 and two pressure regulation valve signals, and this makes it possible to the letter by distance detector
Number control the action of telescopic cylinder 6.
The roller of sweeper suction nozzle 7 in use can wear, after rolling wheel wear between suction nozzle 7 and ground between
Gap can change, now if not adjusting the gap between suction nozzle 7 and ground, in the course of the work, the debris meeting on road surface
Interfered with suction nozzle 7, damage suction nozzle 7.During sweeper operation of the present utility model, the dead electricity of magnetic valve 4, the bottom of magnetic valve 4
Connect in pipeline, entered by the gas of magnetic valve 4 in the rodless cavity of telescopic cylinder 6, now controller detects according to distance
The signal of device adjusts the pressure of the second pressure regulator valve 5, declines suction nozzle 7, until the terrain clearance of suction nozzle 7 reaches requirement, and clearly
Car is swept in operation, distance detector detects the terrain clearance of suction nozzle 7 in real time, and controller controls according to the signal of distance detector
Telescopic cylinder 6 acts, and the terrain clearance of suction nozzle 7 is still adjusted in time in operation, ensures operation quality.After the completion of operation,
Need to lift suction nozzle 7, now magnetic valve 4 obtains electric, the upper gas connected in pipeline, from magnetic valve 4 passed through of magnetic valve 4
Into the rod chamber of telescopic cylinder 6, the first pressure regulator valve 3 of now controller control acts, and makes the gas in the rod chamber of telescopic cylinder 6
Pressure rise, telescopic cylinder 6 shrinks, and so as to drive suction nozzle 7 to rise, until rising to setting position, completes lifting for suction nozzle 7.Electricity
The sequence of movement of magnet valve 4 is as shown in figure 4, YA is magnetic valve in figure.Sweeper of the present utility model is according to distance detector
Signal controls the action of telescopic cylinder 6, so as to realize the adjust automatically of the terrain clearance of suction nozzle 7, solves and inhales in the prior art
The problem of terrain clearance adjustment of mouth 7 is inconvenient.
