DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] Referring to Figures 1-7 , an earth-moving equipment with a high-pressure spraying and swirling function is provided in an embodiment of the present application, including a main body and a cleaning component. A spraying and swirling pile 10 is arranged on the main body. The spraying and swirling pile 10 is used for storing and spraying slurry. The spraying and swirling pile 10 is connected to a hydraulic unit 11, and the hydraulic unit 11 is used for adjusting the angle of the spraying and swirling pile 10. Baffles 2 are arranged on both sides of the main body. The cleaning component includes a water tank 3 and a movable seat 4 at the bottom of the water tank 3. The movable seat 4 is slidably connected to the baffle 2. A driving member for driving the baffle 2 to move horizontally is arranged on the baffle 2. A turntable 41 is rotatably installed on the movable seat 4. A nozzle 42 is arranged on the turntable 41. The nozzle 42 is communicated with the water tank 3 through a pipeline. An adjusting component is arranged on the movable seat 4. The adjusting component is used for driving the turntable 41 to rotate when the movable seat 4 moves horizontally to change the opening direction of the nozzle 42.

[0025] In the earth-moving equipment in the embodiment of the present application, a spraying and swirling pile 10 is arranged on the equipment, which can be used for grouting operations. The cleaning component arranged below the baffle 2 can clean the crawler through the water tank 3 and the nozzle 42. The angle of the nozzle 42 can be adjusted through the adjusting component to improve the cleaning effect of the crawler, effectively remove the soil and mortar on the crawler, and reduce the waste of manpower while improving the efficiency.

[0026] The driving member includes a motor 22 installed on the baffle 2 and a lead screw 21 rotatably installed on the baffle 2. The motor 22 drives the lead screw 21 to rotate. The lead screw 21 is in threaded cooperation with the movable seat 4. A guide plate is connected between the movable seat 4 and the water tank 3. A strip-shaped groove 23 for the guide plate to pass through is arranged on the baffle 2. The strip-shaped groove 23 is arranged parallel to the lead screw 21. When the motor 22 works, it will drive the lead screw 21 to rotate. The lead screw 21 is in threaded cooperation with the guide plate, and during the working process, it will drive the guide plate and the water tank 3 and the movable seat 4 at both ends of the guide plate to move, so as to change the position of the nozzle 42 and realize the cleaning of different positions on the crawler. When the angle of the nozzle 42 deflects, the bent parts at both ends of the crawler can be better cleaned.

[0027] Exemplarily, the adjusting assembly includes a guide rod 5 movably mounted on the movable seat 4. A guide groove is provided on the guide rod 5. The guide rod 5 coincides with the axial direction of the turntable 41. The guide rod 5 penetrates through the turntable 41. A guide groove is provided on the guide rod 5. A through hole for the guide rod 5 to pass through is provided on the turntable 41. A guide block cooperating with the guide groove is provided in the through hole. When the guide rod 5 moves in the movable seat 4, the turntable 41 is driven to rotate.

[0028] Among them, the guide groove on the guide rod 5 includes a first guide groove 51, a second guide groove 52 and a third guide groove 53. The two ends of the second guide groove 52 are respectively communicated with the first guide groove 51 and the second guide groove 52. The first guide groove 51 and the third guide groove 53 are bent and the bending direction extends along the length direction of the guide rod 5 and bends towards the circumferential direction of the guide rod 5. The second guide groove 52 is arranged along the length direction of the guide rod 5.

[0029] The nozzle 42 is arranged at the bottom of the turntable 41. When the guide rod 5 moves horizontally, the guide block in the through hole of the turntable 41 cooperates with the guide groove, and acts on the turntable 41 through the guide groove, so that the turntable 41 rotates to a certain extent. During the rotation of the turntable 41, the angle of the nozzle 42 is adjusted. The orientation of the nozzle 42 is changed, so that the nozzle 42 can better clean the crawler. The structure of the guide groove adopts a segmented design. When the middle second guide groove 52 cooperates with the turntable 41, even if the guide rod 5 moves, the turntable 41 will not be driven to rotate. Only when the first guide groove 51 and the third guide groove 53 cooperate with the turntable 41 can driving be achieved, thereby controlling a small-angle adjustment of the nozzle 42 on the turntable 41.

[0030] Exemplarily, a first movable groove 44 is provided in the movable seat 4. The guide rod 5 is movably mounted in the first movable groove 44. A first piston 45 is provided in the first movable groove 44. The first piston 45 abuts against the inner wall of the first movable groove 44 and is slidably mounted in the first movable groove 44. The first piston 45 is connected to the end of the guide rod 5. A second movable groove 46 communicating with the first movable groove 44 is provided in the movable seat 4. Among them, the first movable groove 44 and the second movable groove 46 are horizontally arranged. Between the end of the first movable groove 44 and the end of the second movable groove 46, they are connected by a transverse pipeline. A second piston 47 is movably mounted in the second movable groove 46. The second piston 47 is connected with a movable block 7. A threaded rod 71 is provided on the movable block 7. The threaded rod 71 is in threaded cooperation with the movable block 7 and drives the movable block 7 and the second piston 47 to slide along the second movable groove 46. A gear 43 is also rotatably mounted on the movable seat 4. The gear 43 is connected to the threaded rod 71. The axes of the gear 43 and the threaded rod 71 coincide. Two racks 24 are provided at the bottom of the baffle 2. The racks 24 are respectively arranged at positions near both ends of the bottom of the baffle 2. The positions of the racks 24 and the gear 43 correspond to each other.

[0031] The rack 24 at the bottom of the baffle 2 cooperates with the gear 43 on the movable seat 4. When the movable seat 4 moves horizontally driven by the lead screw 21, the gear 43 and the rack 24 gradually approach each other. After the rack 24 and the gear 43 come into contact, the continuous movement of the movable seat 4 will cause the gear 43 to rotate. During the rotation of the gear 43, the threaded rod 71 is driven to rotate. The threaded rod 71 is in threaded cooperation with the movable block 7. A threaded hole adapted to the threaded rod 71 is provided in the movable block 7, and the movable block 7 moves horizontally. The movement of the movable block 7 drives the second piston 47 to move, thereby changing the air pressure in the first movable groove 44 and the second movable groove 46. Under the action of the air pressure, the first piston 45 moves horizontally. When the first piston 45 moves, it drives the guide rod 5 to move horizontally, thereby realizing the drive of the guide rod 5 and the turntable 41 to change the angle of the nozzle 42 at the bottom of the turntable 41. Since the movable seat 4 reciprocates, the directions of contact between the gear 43 and the racks 24 on both sides are different. When approaching the two ends of the baffle 2, the directions of deflection of the nozzle 42 at the bottom of the turntable 41 are also different, so as to effectively clean the positions at both ends of the crawler belt.

[0032] Exemplarily, an electric push rod 6 is provided at the bottom of the turntable 41. The fixed end of the electric push rod 6 is arranged on the turntable 41, and the movable end of the electric push rod 6 is connected to the nozzle 42 to adjust the height of the nozzle 42. An activity tube 8 is also arranged in the movable seat 4. One end of the activity tube 8 communicates with the second movable groove 46. A third piston 82 is arranged in the activity tube 8. The third piston 82 moves along the activity tube 8. A contact 83 is arranged at one end of the third piston 82 away from the second movable groove 46. A contact head 84 adapted to the contact 83 is arranged on the inner wall of the end of the activity tube 8. The contact head 84 and the contact 83 are both electrically connected to the electric push rod 6. When the contact head 84 and the contact 83 come into contact, the electric push rod 6 enters the extended state. A driving rod is arranged on the movable block 7. The driving rod includes a transverse rod 72 connected to the movable block 7 and a longitudinal rod 73 connected to the transverse rod 72. An external magnet 74 is arranged at the end of the longitudinal rod 73. A rubber stopper 81 is movably arranged in the activity tube 8. One end of the rubber stopper 81 is located outside the activity tube 8. An internal magnet 86 adapted to the external magnet 74 is arranged on the rubber stopper 81. The longitudinal rod 73 drives the rubber stopper 81 to move, and the moving direction of the rubber stopper 81 is perpendicular to that of the third piston 82.

[0033] The driving rod is arranged on the movable block 7. When the movable block 7 moves, it will drive the driving rod to move horizontally together. As described above, the movement of the movable block 7 will change the air pressure in the first movable groove 44 and the second movable groove 46, so as to realize the driving of the guide rod 5 and the turntable 41. When the air pressure rises to a certain level, due to the guide groove, the guide rod 5 can no longer move, but the air pressure in the second movable groove 46 continues to rise. The driving rod moves and drives the rubber stopper 81 through the structure of the outer magnet 74 and the inner magnet 86. After the rubber stopper 81 moves, the movable tube 8 communicates with the second movable groove 46. Under the action of the air pressure, the third piston 82 moves horizontally and gradually approaches the end of the movable tube 8. The contact 84 contacts the contact 83, and the electric push rod 6 enters the extended state. At this time, the movable seat 4 and the nozzle 42 both move to a position close to the end of the baffle 2. On the basis of the angle deflection of the nozzle 42, the electric push rod 6 drives the nozzle 42 to move downward a small distance, reducing the height of the nozzle 42, which can clean the crawler more effectively.

[0034] A reset member 85 is arranged on the third piston 82. One end of the reset member 85 is connected to the third piston 82, and the other end is connected to the end of the movable tube 8. The reset member 85 can be a reset spring. During the reverse movement of the movable seat 4, the movable block 7 also moves in the reverse direction, and the air pressure in the second movable groove 46 decreases. Under the action of the reset member 85, the third piston 82 moves, the contact 84 and the contact 83 are separated, the electric push rod 6 enters the contracted state, and the height of the nozzle 42 is reset. The driving rod drives the rubber stopper 81 to move in the reverse direction to block the movable tube 8.

[0035] The working principle of the embodiment of the present application will be described below: When the crawler needs to be cleaned, the water tank 3 and the nozzle 42 are turned on, and clean water is sprayed through the nozzle 42. The motor 22 does not drive the movable seat 4 and the water tank 3 to move horizontally through the lead screw 21. When moving to both ends, the gear 43 and the rack 24 are in contact with each other, the gear 43 rotates, and during the rotation of the gear 43, the threaded rod 71 is driven to rotate. The threaded rod 71 is in threaded cooperation with the movable block 7, so that the movable block 7 moves horizontally. The movement of the movable block 7 drives the second piston 47 to move, thereby changing the air pressure in the first movable groove 44 and the second movable groove 46. Under the action of the air pressure, the first piston 45 moves horizontally, and when the first piston 45 moves, it drives the guide rod 5 to move horizontally.

[0036] The guide groove on the guide rod 5 cooperates with the turntable 41. The movement of the guide rod 5 is converted into the rotation of the turntable 41. When the turntable 41 rotates, the angle of the nozzle 42 at the bottom of the turntable 41 can be changed, so as to better clean both ends of the crawler. In addition, on the basis of the angle deflection of the nozzle 42, the electric push rod 6 can also drive the nozzle 42 to move downward for a short distance, reducing the height of the nozzle 42, and can more effectively clean the crawler.

[0037] As mentioned above, it is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
