DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Referring to the attached Figures 1-3 description, as Figure 1 shown, a mining excavation device in an embodiment of the present utility model includes a main body 1, as Figure 2As shown in the figure, a fixed housing 2 is fixedly installed on one side of the main body 1. A bearing 3 is provided inside the fixed housing 2. A turntable 4 is provided inside the bearing 3. A connecting shaft 5 is fixedly installed on one side of the turntable 4. The connecting shaft 5 is rotatably connected inside the fixed housing 2. A fixed collar 6 is fixedly installed at one end of the connecting shaft 5. A main rod 7 is sleeved inside the fixed collar 6. A cavity 8 is fixedly installed at the top of the main rod 7. A spray head 9 is rotatably connected inside the cavity 8. A positioning shaft 10 is fixedly installed on one side of the spray head 9. The positioning shaft 10 is rotatably connected inside the cavity 8. A motor 11 is fixedly installed outside the cavity 8. The positioning shaft 10 is fixedly installed at the output end of the motor 11. A water delivery pipe 12 is communicated and provided at the top of the spray head 9. The water delivery pipe 12 is slidably connected inside the cavity 8, as Figure 1 shown, a counterweight 13 is fixedly installed at the bottom of the main rod 7, as Figure 3 shown, a first guide wheel 14 is rotatably connected on one side of the main body 1. The water delivery pipe 12 is slidably connected outside the first guide wheel 14. A second guide wheel 15 is rotatably connected on one side of the main body 1. Through the arrangement of the first guide wheel 14 and the second guide wheel 15, the water delivery pipe 12 can be stored under the limitation of the first guide wheel 14 and the second guide wheel 15, so as to avoid damage.
[0018] It should be noted that, among them, by installing a water tank and a water pump on the excavator body, connecting the water pump with the water delivery pipe 12. When mining and excavating a mine, by starting the water pump, the water in the water tank is conveyed into the spray head 9 through the water delivery pipe 12 and sprayed out through the spray head 9. Since the spray head 9 is located above the bucket, when the spray head 9 sprays water mist, it can reduce the dust generated by excavation to avoid the spread of dust and improve air pollution. Since the main body 1 is in a frequent motion state during work, and under the action of the fixed housing 2, the main rod 7 will rotate at any time, and a vertical downward force is applied to the main rod 7 through the arrangement of the counterweight 13, so that the main rod 7 always tends to be in a vertical state, so that the water mist sprayed by the spray head 9 will not deviate for a long time due to the movement of the main body 1, so as to maintain the effect of reducing dust on the dust, and at the same time, by starting the motor 11, the spray head 9 can be driven to rotate correspondingly, so as to change the angle of the water mist sprayed by the spray head 9, so that the water mist can be adjusted according to the actual situation to ensure that the purpose of good dust reduction can be achieved.
