Poor mobility. In many fire scenes with complex terrain, ground fire fighting vehicles cannot arrive at the scene, and most of the fire fighting personnel rush to the scene on foot; low fire fighting efficiency. Now, forest fire fighting is mainly done with water all over the world. During the fire fighting process, it is often difficult to keep the water uniform, and even evaporates directly when approaching the fire source; pollute the environment, and sometimes chemical fire extinguishing agents are used when conditions are good. Although the fire fighting effect is improved, it will cause damage to the ecological environment of the forest. Until now, there is still no set of green and environmentally friendly chemical fire extinguishing agents; low safety. During the fire fighting, fire fighting personnel often suffer from burns, hypoxia and suffocation and other accidents; high cost.

[0035] The present invention provides a method for using an unmanned forest fire extinguishing fire truck, comprising the following steps:

[0036] Step 1: Start the tilt adjustment electric cylinder 17 to rotate the transport frame 14 around the rotating main shaft 19, thereby pressing the position of the loosening and collecting mechanism 1 down to near the ground;

[0037] Step 2: Start the angle adjustment motor 7, adjust the relative angle between the soil breaking shovel 9 and the ground through the loosening angle adjustment link 8, and then start the soil breaking motor 10. When the soil shovel wheel 11 rotates, the soil is broken by the pick 12 and rolled into the soil breaking shovel 9;

[0038] Step 3: The soil falls onto the conveyor belt 16 through the soil breaking shovel 9, and then falls into the soil storage box 24 under the transmission of the conveyor belt 16;

[0039] Step 4: When the photoelectric sensor 33 senses that the launching bucket 32 ​​is in a horizontal state, the soil storage box 24 flows the soil into the launching bucket 32, and then the soil in the launching bucket 32 ​​is ejected through the rotation of the soil ejecting motor 28;

[0040] Step 5: During normal movement, the driving motor 42 drives the active bevel gear 43 and the driven bevel gear 44 to rotate, thereby driving the roller 45 to rotate and then move through the long crawler 46. At this time, the electromagnetic clutch 35 is in a disconnected state, and the obstacle-crossing motor 34 rotates while driving the triangular crawler 40 through the driving gear 37, the transmission gear 38 and the driven wheel 39;

[0041] Step 6: When encountering a pothole road, the electromagnetic clutch 35 is closed. At this time, when the obstacle motor 34 rotates, it will rotate with the triangular escape wheel frame 36, so as to quickly pass through obstacles or potholes.

[0042] During specific use, the user first starts the tilt adjustment electric cylinder 17 to rotate the transport frame 14 around the rotating main shaft 19, thereby pressing the position of the loosening and collecting mechanism 1 down to the ground, and then starts the angle adjustment motor 7, and adjusts the relative angle between the soil-breaking shovel 9 and the ground through the soil-loosening angle adjustment connecting rod 8, and then starts the soil-breaking motor 10. When the soil-shoveling wheel 11 rotates, the soil is broken and rolled into the soil-breaking shovel 9 through the cutting teeth 12, and then the soil falls onto the conveyor belt 16 through the soil-breaking shovel 9, and then falls into the soil storage box 24 under the drive of the conveyor belt 16, and then when the photoelectric sensor 33 senses that the launching bucket 32 ​​is in a horizontal state, the soil storage box 24 flows the soil into the launching bucket 32, and then through the soil-throwing electric The rotation of the machine 28 ejects the soil in the launching bucket 32. When moving normally, the driving motor 42 drives the active bevel gear 43 and the driven bevel gear 44 to rotate, thereby driving the roller 45 to rotate and then moving through the long crawler 46. At this time, the electromagnetic clutch 35 is in a disconnected state. When the obstacle motor 34 rotates, it rolls with the triangular crawler 40 through the driving gear 37, the transmission gear 38 and the driven wheel 39. When encountering a pothole road, the electromagnetic clutch 35 is closed. At this time, when the obstacle motor 34 rotates, it will rotate with the triangular escape wheel frame 36, so as to quickly pass through obstacles or potholes. The above is the overall workflow of the present invention. Just repeat this step when you use it next time.
