The present invention can regulate discharge velocity automatically according to feed height, and making feed height is a setting value, has guaranteed the unobstructed of discharge, simultaneously, has saved the energy.
Description of drawings:
Fig. 1 is apparatus of the present invention structural representation:
Fig. 2 is apparatus of the present invention control circuit figure.
The specific embodiment:
The present invention be directed to the design that the existing defective of present road surface cold milling and planing machine milling operation is carried out.It is by being provided with the height of materials controller of detectable milling cutter head feed height on every side on the milling machine frame, pass to controlling organization by the detected signal of this controller, send signal for the control valve of control discharge mechanism and feed mechanism action by controlling organization, with the running speed of control discharge mechanism and feed mechanism, realize the Self Adaptive Control of milling machine discharge velocity.
The present invention has designed a device according to said method.As shown in Figure 1, apparatus of the present invention comprise frame 1, milling and planing drum 6, walking mechanism 9, discharge mechanism 4 and feed mechanism 3, milling and planing drum 6 is installed on the frame 1, be positioned at frame 1 below, periphery is equipped with the milling cutter head 10 that can rotate, by the milling and planing drum driving mechanisms control, walking mechanism 9 can be made of crawler belt or tire, be located at milling and planing drum 6 forward and backward positions, discharge mechanism 4 is positioned at milling and planing drum 6 anterior locations, feed mechanism 3 is positioned at frame 1 front, and discharge mechanism 4 and feed mechanism 3 drive run-in synchronism by hydraulic system.Milling and planing drum 6 constantly rotation makes distribution cutter head 10 continuous milling road surfaces thereon, and the material that milling goes out is taken away through discharge mechanism 4 and feed mechanism 3.The present invention is characterised in that and on the frame 1, above being positioned at the other stockpiles of milling and planing drum 6 height of materials controller 7 is being set that this height of materials controller 7 joins with the control device 5 that is connected to form by control circuit.
As shown in Figure 2, control device of the present invention 5 is made up of control circuit, it comprises that height of materials controller 7 and discharge belt rotate electromagnetic valve Y1, in the described height of materials controller 7 ultrasonic transmitter and recipient are housed, which is provided with A, C, three interfaces of D, wherein A mouth and fuse F1 join, C mouth and V-connect, D mouth and discharge belt rotate electromagnetic valve Y1 and join, the discharge belt rotates electromagnetic valve Y1 and joins with discharge mechanism 4 and feed mechanism 3, rotate the control of electromagnetic valve Y1 by 7 pairs of discharge belts of height of materials controller and control the running speed of discharge mechanism 4 and feed mechanism 3, thereby reach purpose of the present invention.
