As shown in fig. 8, when the intelligent roller brush device is used, the chassis attachment 1 is mounted on the chassis of the snow-removing spreader 40.
After the brush seedlings on the roller brush assembly 8 are abraded, the brush seedlings are automatically tracked and adjusted, so that the brush seedlings always keep the optimal cleaning width.
The operating handle is downward, the control system controls the roller brush lifting cylinder 30 to move so that the roller brush assembly 8 falls, the roller brush assembly 8 is finely adjusted, the roller brush assembly 8 detects the ground pressure, when the roller brush pressure is within a set pressure range, the cleaning width of brush seedlings is about 70-90 mm, meanwhile, the roller brush driving motor 27 rotates at a high speed, and the roller brush assembly 8 enters an operation mode.
The operating handle is pulled to the left, the piston rod of the right roller brush oscillating cylinder extends out, the piston rod of the left roller brush oscillating cylinder retracts, the roller brush assembly 8 oscillates leftwards, and accumulated snow is cleaned to the left direction of the vehicle in the advancing process;

the operating handle is upward, the piston rod of the roller brush lifting cylinder 30 extends out, the roller brush assembly 8 is lifted, the roller brush assembly 8 stops rotating, and the operation is finished;
before 8 high-speed operations of roller brush subassembly, need finely tune the detection, the main effect that finely tunes the detection is, and the brush seedling is to ground pressure in the within range of setting for, can guarantee like this that the width of cleaning of brush seedling to ground reaches the requirement, can not produce transition loss to the brush seedling like this, can reach the purpose of removing clean snow again.
As shown in fig. 10, the operation of the roller brush assembly 8 is controlled as follows:
in step S1, the control system sets the initial value of the number of times N to 15.
In step S2, the control system controls the roller brush assembly 8 to rotate at a low speed (generally less than or equal to 250r/min) and fall.
And step S3, the working pressure of the roller brush driving motor 27 is used as the seedling brushing pressure P to the ground, and the seedling brushing pressure P to the ground is fed back to the control system.
And step S4, the control system judges whether the pressure P of the brush seedlings on the ground is within the set pressure range of 40-60 bar, if so, the step S7 is carried out, otherwise, the step S5 is carried out when the P value is judged to be greater than 60bar, and the step S6 is carried out when the P value is judged to be less than 40 bar.
And step S5, the control system enables the coil of the fine adjustment electromagnetic valve to be electrified, so that the piston rod of the roller brush lifting cylinder 30 extends once, the value N is reduced by 1, and the step S4 is returned. The length of time that the coil of the fine solenoid is energized determines the distance that the piston rod of the roller brush lift cylinder 30 extends.
In step S6, the control system energizes the other set of coils of the trim solenoid valve, thereby retracting the piston rod of the roller brush lift cylinder 30 once, adding 1 to the value of N, and returning to step 4. The length of time that the other set of coils of the fine solenoid valve are energized determines the distance that the piston rod of the roller brush lift cylinder 30 is retracted.
And step S7, determining that the cleaning width of the brush seedlings of the roller brush assembly 8 meets the requirement.
In step S8, it is determined whether the N value is greater than the set threshold 120, if so, the process proceeds to S9, otherwise, the process proceeds to S10.
And step S9, the roller brush assembly 8 is rotated at a low speed, and the brush seedlings are determined to be worn to a short extent and need to be replaced in time.
In step S10, the roller brush unit 8 is rotated at a high speed of 1800rpm, and the roller brush unit 8 enters an operating state.
As can be understood by those skilled in the art, the longer the roller brush assembly is used, the shorter the brush seedlings become, so that the downward fine adjustment times (recorded by the N value) become larger, when the N value is larger than 120, the brush seedlings are worn to a short extent, at this time, the roller brush is always detected, the cleaning width of the brush seedlings on the ground cannot meet the cleaning requirement, and the brush seedlings need to be replaced.
The control system adopts a structure known in the field, and comprises input elements such as a controller, a display, a switch and a sensor, and execution elements such as an electromagnetic valve, a hydraulic pump and a relay; the controller is communicated with the chassis ECU through the CAN2 to read the speed of the chassis; the controller controls the operation of the roller brush pump according to the vehicle speed so as to drive the roller brush driving motor 27 to operate.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, as various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the scope defined by the claims of the present invention shall be within the protection scope of the present invention.
