[0029] The specific configuration and functions of the water spray assembly 2 and the reinforcement assembly 3 are described in detail below.
[0030] Reference Figure 2 and Figure 3 as well as Figure 4 As shown, in this embodiment: the water spray assembly 2 includes a square tube 21 fixedly connected to the upper end of the bucket 7, the left end of the square tube 21 is fixedly connected to a nozzle 22, and one end of the square tube 21 is fixedly connected to a water inlet pipe 23 of an external water pump. By setting the water spray assembly 2, when the bucket 7 shovels up gravel, the water pipe is first connected to the external water pump, the water pump is started, and water is input into the square tube 21, so that water mist is sprayed from the nozzle 22, so that the dust on the shoveled gravel is wetted by the water mist, and when the bucket 7 reaches the gravel, the nozzle The nozzle 22 still sprays water mist, and the dust is wetted by the water mist for the second time, thereby reducing the dust as much as possible. The inner wall of the nozzle 22 is slidably connected with a perforated disk 24, and the right end of the perforated disk 24 is fixedly connected with uniformly distributed needles 25. The perforated disk 24 is reciprocated by the pushing mechanism, so that the needles 25 are always in the holes and move back and forth. Since the needles 25 are thin, water can always flow through the holes. When the nozzle 22 is blocked, several holes are blocked first, and then all are blocked little by little. Since the needles 25 are always in the holes, the nozzle 22 is blocked. The needle 25 moves back and forth in the hole to avoid blockage. The arc surface of the needle 25 is fixedly connected with a plurality of evenly distributed barbed hooks 26. By setting the barbed hooks 26, the blocking needle 25 moves back and forth and the barbed hooks 26 can saw the blockage like a saw. The inner wall of the square tube 21 is rotatably connected with a rotating shaft 27. The left end of the rotating shaft 27 is fixedly connected with a water turbine 29. The water flows through the water turbine 29 to rotate it, thereby driving the rotating shaft 27 to rotate. The arc surface of the rotating shaft 27 is fixedly connected with a plurality of evenly distributed cams 28. The left end of the perforated disk 24 is fixedly connected with a push rod 210. The rotating shaft 27 rotates, causing the cam 28 to rotate, thereby pushing the push rod 210. The right end of the perforated disk 24 is fixedly connected with a magnetic ring 1 211. One side of the inner wall of the nozzle 22 is fixedly connected with a magnetic ring 212. The push rod 210 is pushed, thereby driving the perforated disk 24 to move. By setting the magnetic ring 1 211 and the magnetic ring 212, they repel each other when they are close to each other, thereby resetting the perforated disk 24 and causing the perforated disk 24 to reciprocate.
[0031] Reference Figure 2As shown, in this embodiment: the reinforcement component 3 includes an L-shaped block 31 fixedly connected to the inner wall of the bucket 7, a triangular block 32 is slidably inserted on one side of the L-shaped block 31, and a bolt 33 is slidably inserted on the front of the L-shaped block 31. By setting the L-shaped block 31 and the triangular block 32, the bolt 33 penetrates the L-shaped block 31 and the triangular block 32, and then tightens the L-shaped block 31 and the triangular block 32 to fix them, thereby assisting in strengthening the strength of the bucket 7. A plurality of triangular blocks 32 and L-shaped blocks 31 are provided, and the plurality of triangular blocks 32 and L-shaped blocks 31 are evenly distributed. By providing a plurality of triangular blocks 32 and L-shaped blocks 31, the strength of the bucket 7 is further strengthened.
[0032] Working principle:
[0033] When using the electric scraper, the worker remotely controls the electric scraper through a remote controller. The antenna on the electric scraper receives the signal command sent by the antenna on the remote controller (the remote controller is an existing product sold on the market, and the specific remote control method is not described in detail here as the prior art). The crushed stone is shoveled up by the operating arm 5 and the cylinder 1 6, and the crawler 4 is driven to rotate by the motor in the machine body 1, so as to move to the unloading point, and then the cylinder 2 8 is used to unload the material, so as to shovel the crushed stone in the narrow space under the mine. When the bucket 7 shovels up the crushed stone, the water pipe is first connected to the external water pump, and the water pump is started. The water pump is installed in the water tank, and water is input into the square pipe 21 through the water inlet pipe 23, so that the water mist is sprayed by the nozzle 22, so that the dust on the shoveled gravel is wetted by the water mist. When the bucket 7 reaches the crushed stone, the nozzle 22 still sprays water mist, and the dust is wetted by the water mist for the second time, thereby achieving the effect of reducing the dust as much as possible. The water flows through the water turbine 29 to rotate it, thereby driving the rotating shaft 27 to rotate, and the rotating shaft 27 rotates. The shaft 27 rotates, causing the cam 28 to rotate, thereby pushing the push rod 210. The push rod 210 is pushed, causing the perforated disk 24 to move. By setting the magnetic ring 1 211 and the magnetic ring 212, they repel each other when they are close to each other, thereby resetting the perforated disk 24, and then causing the perforated disk 24 to reciprocate, so that the needle 25 is always in the hole and moves back and forth. Since the needle 25 is thin, water can always flow through the hole. When the nozzle 22 is blocked, several holes are blocked first, and then all are blocked little by little. Since the needle 25 is always in the hole and moves back and forth to avoid blockage, the barbed hook 26 is set, the needle 25 is blocked and moves back and forth. The barbed hook 26 can saw the blockage like a saw. By setting an L-shaped block 31 and a triangular block 32, after the bolt 33 penetrates the L-shaped block 31 and the triangular block 32, the L-shaped block 31 and the triangular block 32 are tightened to fix them, thereby assisting in strengthening the strength of the bucket 7. By setting multiple triangular blocks 32 and L-shaped blocks 31, the strength of the bucket 7 is further strengthened.
