[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See Figures 1 to 2 as shown in;

[0031] A front panel assembly of an unmanned mining truck in this embodiment, the front panel assembly includes:

[0032] The front panel welding 1 is connected to the bottom plate 6 of the mining truck at the lower part of the front panel welding 1, and the upper part of the front panel welding 1 is connected to the top plate 7 of the mining truck;

[0033] The high-pressure water spray pipe assembly 2 integrated at the lower part of the front panel welding 1, and the high-pressure water spray pipe assembly 2 is connected with a plurality of high-pressure nozzles; and

[0034] The water tank assembly 4 integrated on the upper part of the top plate 7;

[0035] The lifting cylinder 5 is installed on the lower surface of the top plate 7.

[0036] Specifically, this embodiment discloses a front panel assembly, which mainly includes a front panel welding 1, a high-pressure water spray pipe assembly 2, a lifting cylinder fixing seat 3 and a water tank assembly 4; among them, a row of water spray holes are opened at the lower part of the front panel welding 1, and the high-pressure water spray pipe assembly 2 is installed at this place. According to the position and quantity of the opened water spray holes, high-pressure nozzles are installed at the corresponding positions, and the high-pressure nozzles face the bottom plate 6 of the mining truck, and are used to remove the residual material accumulation on the bottom plate 6 by the impact of the high-pressure nozzles when residual material accumulation occurs during unloading. At the same time, the water tank assembly 4 and the lifting cylinder fixing seat 3 are installed on the top plate 7 of the mining truck in this embodiment.

[0037] Preferably, a water tank assembly mounting plate is provided on the upper surface of the top plate 7 in this embodiment, and the water tank assembly 4 is installed on the water tank assembly mounting plate; the high-pressure water spray pipe assembly 2 is connected to the water tank assembly 4 through a water pump.

[0038] A lifting cylinder fixing seat mounting plate is provided on the lower surface of the top plate 7, and the lifting cylinder fixing seat 3 of the lifting cylinder 5 is installed on the lifting cylinder fixing seat mounting plate; the lifting cylinder 5 is installed below the lifting cylinder fixing seat 3.

[0039] Secondly, the lifting cylinder fixing seat 3 of this embodiment is connected to the lifting cylinder 5 through a pin shaft. Additionally, in this embodiment, since the cylinder fixing seat assembly is arranged at the top and its position is farther from the carriage rotation axis than the front of the front panel welding 1, the lifting force required to lift the carriage is smaller. As a result, the lifting cylinder 5 can be smaller, saving costs.

[0040] In order to be able to monitor the water level in the water tank assembly 4 in real time, a water level sensor is provided in the water tank assembly 4 of this embodiment. It reminds the driverless mining truck control system to add water when the water volume is low and sends a signal to remind that the water is full when adding water.

[0041] During use, during the unloading process, when the weighing system of the driverless mining truck detects residual ore in the carriage, the control system of the driverless mining truck sends a signal to start the high-pressure water pump, and the high-pressure nozzles on the high-pressure water pipe assembly 2 start to spray water to clean the residual ore on the carriage bottom plate 6. When the weighing system of the driverless mining truck detects that the residual ore in the carriage has been cleaned up, the control system of the driverless mining truck sends a signal to turn off the high-pressure water pump.

[0042] In the above technical solution, a front panel assembly of a driverless mining truck provided by the present utility model has the following beneficial effects:

[0043] The front panel assembly of the present utility model uses high-pressure nozzles to impact the remaining materials, reducing the accumulation of bottom plate remaining materials, thereby improving the working efficiency of the mining truck and reducing the operating cost; and it can reduce the lifting force, thereby reducing the diameter of the lifting cylinder 5 and reducing the material cost.

[0044] The upper end of the lifting cylinder fixing seat 3 of the front panel assembly of the present utility model is connected to the front panel welding 1, and the lower end is connected to the lifting cylinder 5. The connection is achieved by a pin shaft, which is more convenient and time-saving for assembly compared with the existing bolt connection, thereby reducing the production cost of the mining truck.

[0045] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
