[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As shown in the figure, the present invention is composed of a traveling frame 1, a cantilever adjusting device 2, a cantilever 3, a bucket wheel 4, a suspended mobile frame 5, a second belt conveyor 6, and a third belt conveyor 7.

[0032] 1. Traveling frame 1: It consists of a support frame, drive, brake and positioning components. The support frame bears the weight of the equipment itself and the impact of the operation process, and transmits the force to the track. The drive component provides power for the movement of the equipment on the track surface, using an external power supply or a vehicle-mounted battery. The brake and positioning components provide stable and accurate working conditions for the equipment, and can provide equipment positioning data and control basis for intelligent control.

[0033] 2. Boom adjustment device 2: It is mainly composed of hydraulic drive, hydraulic cylinder and supporting structure. The system controls the angle of boom 3 and then the position of bucket wheel 4 through the extension and contraction of hydraulic cylinder. The angle of boom 3 is adjusted through the weighing measurement feedback on the second belt conveyor 6 to realize closed-loop control. It provides the control basis for the reverse transportation operation of matching the material level in the pool for intelligent control.

[0034] 3. Cantilever 3: It is composed of a corrugated sidewall belt conveyor and a cantilever structure. The corrugated sidewall belt conveyor can transport the materials dug by the bucket wheel when the cantilever 3 is positioned at a large angle, and transfer them to the second belt conveyor 6. The cantilever structure serves as the frame of the corrugated sidewall belt conveyor, and also as a load-bearing structure supporting the bucket wheel 4, and is also driven by the cantilever adjustment device 2.

[0035] 4. Bucket wheel 4: It consists of a drive device, a bucket and wear-resistant lining, a bucket wheel frame, a material dumping chute, etc. The drive device provides power for the bucket wheel to rotate and take materials. The bucket, bucket wheel frame, and material dumping chute realize the excavation of materials and dumping the materials to the corrugated sidewall belt conveyor.

[0036] 5. Suspension type mobile frame 5: It is mainly composed of hydraulic drive, hydraulic cylinder 51 and suspension frame 52. Through the extension and retraction of the hydraulic cylinder, the second belt conveyor 6 and the third belt conveyor 7 are controlled to connect with the external material transportation facilities.

[0037] 6. The second belt conveyor 6 and the third belt conveyor 7: The two belt conveyors are controlled by the suspended mobile frame. The two belt conveyors share a common support structure. The second belt conveyor 6 can only rotate horizontally; the third belt conveyor 7 can move along its own length direction when the horizontal positioning is determined. Figure 3 The third belt conveyor 7 is positioned by adjusting the hydraulic system signal of the cantilever 3 to match the torque of the cantilever 3 at different angles to achieve stable operation of the equipment.

[0038] The equipment transports materials according to the following process:

[0039] 1. The equipment is moved and positioned by the drive device on the traveling frame 1.

[0040] 2. The suspended mobile frame adjusts the second belt conveyor 6 and the third belt conveyor 7 to align with the external transport facility;

[0041] 3. Start in sequence: the third belt conveyor 7, the second belt conveyor 6, the cantilever system 3 belt conveyor, and the bucket wheel 4;

[0042] 4. The cantilever adjusting device 2 is lowered, and the third belt conveyor 7 moves synchronously. When the weighing measurement on the belt conveyor 16 increases to the set target, the cantilever adjusting device 2 and the third belt conveyor 7 stop moving; when the weighing measurement on the belt conveyor 16 decreases to the set target, the cantilever adjusting device 2 and the third belt conveyor 7 stop moving. The unloading work at this position is completed.

[0043] Repeat the above 1 to 5 cycles until all materials in the material pool are transported away.

[0044] The present invention is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention. Many other changes and modifications that do not depart from the concept and scope of the present invention should be regarded as the protection scope of the present invention.

[0045] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
