Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-3 The concrete mix material lifting bucket in this embodiment includes a track frame 1. The lower end of the track frame 1 is integrally connected to a base, which is assembled and fixed to the ground by fastening screws, so as to realize the assembly and fixation of the whole equipment to the ground.

[0038] The inner side of the track frame 1 is provided with a track groove, and a hopper 2 rolls in the track groove. The front and rear surfaces of the hopper 2 are equipped with driven wheels that rotatably contact the surface of the track frame 1. The front and rear surfaces of the hopper 2 are also equipped with driving wheels that rotate in the track groove. The track groove is located on the inner sides of both sides of the track frame 1 and is arranged opposite to each other.

[0039] The track frame 1 rolls along the track groove with the driving wheel without disengaging, and when the track frame 1 moves, it cooperates with the driven wheel to roll on the surface of the track frame 1 for stability.

[0040] A positioning pad 23 located directly below the hopper 2 is installed and fixed on the upper surface of the bottom of the track frame 1, ensuring that the hopper 2 is placed stably on the surface of the positioning pad 23 when it moves down to the bottom.

[0041] The surface of the track frame 1 is provided with a lifter, which is connected to the hopper 2. The lifter includes a mounting frame 17 integrally connected to the upper surface of the track frame 1. A pulley 18 rotates circumferentially inside the mounting frame 17. A drive motor 19 is fixedly mounted on the rear surface of the mounting frame 17 by fastening screws. A rotating shaft 21 that rotates with the mounting frame 17 is fixedly mounted on the output shaft of the drive motor 19. A coaxial winding wheel 22 is fixedly mounted on the outside of the rotating shaft 21. A pull rope 20 that passes around the pulley 18 is fixedly wound around the outside of the winding wheel 22. The other end of the pull rope 20 is connected and fixedly connected to the hopper 2.

[0042] It should be added that the drive motor 19 drives the winding wheel 22 on the rotating shaft 21 to rotate and unwind the pull rope 20, and the pulley 18 guides the pull rope 20 to achieve the traction movement of the hopper 2.

[0043] The top right side of the hopper 2 is connected to a corrugated telescopic tube 3, and the other end of the corrugated telescopic tube 3 is connected to a docking seat 4. An electric push rod 5, which is connected and fixed to the docking seat 4, is installed and fixed on the front surface of the hopper 2 by fastening screws. The corrugated telescopic tube 3 is a plastic corrugated hose. The electric push rod 5 drives the docking seat 4 to move, and the corrugated telescopic tube 3 extends and retracts synchronously.

[0044] Please see Figure 4-6 The bottom left side of the hopper 2 is connected to a discharge cylinder 6. A hydraulic push rod 11 is fixed to the left side of the discharge cylinder 6 by fastening screws. A discharge port is provided at the connection between the discharge cylinder 6 and the hopper 2. A switch plate 12 for blocking the discharge port is fixed to the push rod of the hydraulic push rod 11. The hydraulic push rod 11 drives the switch plate 12 to move, thereby opening and closing the discharge port and achieving the purpose of controlling the discharge. The lower surface of the discharge cylinder 6 is connected to an inner cylinder 7. An outer cylinder 8 is slidably connected to the outside of the inner cylinder 7. A sealing cover 9 is connected to the other end of the outer cylinder 8. An electric guide rail 10 connected to and fixed to the outer cylinder 8 is fixed to the outside of the discharge cylinder 6 by fastening screws.

[0045] It should be added that the electric guide rail 10 drives the outer cylinder 8 to slide outside the inner cylinder 7, so that the sealing cover 9 can move and dock with the feed inlet of the mixing tank to seal it.

[0046] A dust collection seat 13 is fixedly installed on the upper surface of the hopper 2. The outer side of the dust collection seat 13 is provided with an air extraction structure. The outer side of the dust collection seat 13 is also provided with a connector. The connector is connected to the hopper 2 and the unloading cylinder 6.

[0047] The connector includes a connecting pipe 14 connected to the upper surface of the dust collection seat 13, a suction pipe 16 connected between the outer side of the connecting pipe 14 and the upper surface of the hopper 2, and a suction pipe 25 connected between the connecting pipe 14 and the upper surface of the unloading cylinder 6.

[0048] The air extraction structure includes an air extraction cylinder 24 connected to the right side of the dust collection seat 13. A motor 26 is installed and fixed inside the air extraction cylinder 24 by fastening screws. A fan blade 27 is installed and fixed at the output shaft of the motor 26. A filter screen 25 is installed and fixed inside the air extraction cylinder 24. The filter screen 25 is an activated carbon filter screen, but is not limited to activated carbon filter screens. The filter screen 25 can be a HEPA filter screen, fiber filter screen, or other filter screens suitable for dust isolation.

[0049] The motor 26 drives the fan blades 27 to rotate, which exhausts the air in the dust collection seat 13 to the right side of the exhaust pipe 24. The filter screen 25 isolates the dust in the dust collection seat 13 to prevent it from being discharged with the air.

[0050] The working principle of the above embodiments is as follows:

[0051] When feeding material into hopper 2, the drive motor 19 is started to drive the winding wheel 22 on the rotating shaft 21 to rotate, and the pull rope 20 on the winding wheel 22 is released. With the help of the pulley 18, the pull rope 20 is pulled by the pull rope 20 to move hopper 2 down the inclined plane on the track frame 1, so that hopper 2 is stably placed on the positioning pad 23.

[0052] Then, the electric push rod 5 is activated to push the docking seat 3 to move. The corrugated telescopic tube 3 extends synchronously, so that the docking seat 3 is inserted into the outside of the conveyor belt for conveying aggregate. Thus, under relatively closed conditions, the aggregate conveyed on the conveyor belt falls into the hopper 2. When feeding, the motor 26 is activated synchronously to drive the fan blade 27 to rotate. When exhausting the air to the outside of the exhaust cylinder 24, the other side of the motor 26 generates suction. By utilizing the interconnection between the exhaust cylinder 24, the dust collection seat 13, the connecting pipe 14, the suction pipe 16 and the hopper 2, it is ensured that the dust rising in the hopper 2 during feeding is sucked into the dust collection seat 13 by the suction pipe 16 for storage. The filter screen 25 is set to isolate the sucked dust and prevent the dust from being discharged from the exhaust cylinder 24.

[0053] After the material is fed into hopper 2, the electric push rod 5 is activated to move and reset the docking seat 3, separating it from the conveyor belt. Based on the above principle, the drive motor 19 is activated to reverse the rotating shaft 21, winding the pull rope 20 and pulling hopper 2 upwards to the top. Then, the electric guide rail 10 is activated, causing the outer cylinder 8 to move downwards outside the inner cylinder 7, simultaneously moving the sealing cover 9 downwards. This allows the sealing cover 9 to seal and dock with the feed inlet of the mixing tank. After docking, the hydraulic push rod 11 is activated to move the switch plate 12, opening... The discharge port is opened so that, in a closed state, the proportioned aggregate in hopper 2 enters the discharge cylinder 6 through the discharge port, and is discharged into the mixing tank through the sealing cover 9. During the discharge, in accordance with the above principle, the motor 26 is started to work. Utilizing the interconnection between the air extraction cylinder 24, dust collection seat 13, connecting pipe 14, suction pipe 2 15 and discharge cylinder 6, the dust generated during discharge is sucked into the dust collection seat 13 through suction pipe 2 15 for storage, ensuring that the rising dust is treated and collected when hopper 2 is loading and unloading, thus achieving the purpose of environmental protection.

[0054] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
