and according to the ore storage conditions of the four ore bins, material level setting is carried out at the upper computer end. The running direction of the sports car is divided into a forward direction and a reverse direction, the forward direction is the running direction from the No. 1 bin to the No. 4 bin of the ore bin 7, and the reverse direction is the reverse direction. If the sports car is required to run in the forward direction, the forward running button is selected on the upper computer. In the forward operation process, when the actual material level on site is lower than the set material level, and the sports car runs to the position of the forward proximity sensor in the cabin, the sports car stops in the cabin, and the material distribution is carried out on the cabin. When the actual material level on site is higher than the set material level, the sports car continues to run, and the next ore bin is compared. The same is true for the reverse operation. The two proximity sensors of each ore bin respectively represent forward (such as the first, third, fifth and seventh proximity sensors J1, J3, J5 and J7) operation signals and reverse (such as the second, fourth, sixth and eighth proximity sensors J2, J4, J6 and J8) operation signals, and the operation position of the sports car can be monitored in real time. When the actual material level of each ore bin is higher than the set material level, the running vehicle stops running. Limit switches are additionally arranged at two ends of a running track of the sports car respectively, and when the sports car contacts the limit switches, the sports car stops immediately, so that production and safety accidents are prevented.
Because the lower end outlet of the material distribution ore bin 7 is connected with the feeding belt, materials are provided for the vibrating screen, the ore supply period of the ore bin is short, and the material distribution ore bin 7 is always in an ore supply state, so that the trolley needs to run in the forward direction and the reverse direction repeatedly, automatic material distribution is realized, and the labor intensity of field personnel is greatly reduced.
The utility model discloses still remain manual control, carry out manual automatic control's switching through manual/automatic change over switch LW, can beat manual fender with manual/automatic change over switch LW, drop into corotation shift knob SB1, stop button SB2 and reversal shift knob SB3 and carry out opening of dolly driving motor and stop and just reverse control, this kind of control does not have PLC to participate in, can only carry out the manual positive and negative rotation that realizes the dolly and open and stop the operation through the signal of manual control level meter. The manual control is only used as an alternative to the automatic control, and is adopted when the related devices of the automatic control need to be maintained and replaced.
