[0001] The utility model relates to the technical field of material conveying equipment, in particular to an electro-hydraulic bucket type scraper sewage discharge and unmanned automatic cleaning device. Background Art

[0002] At present, when most conveyor belts are transporting mineral materials, the return belts will generate a large amount of material spillage along the way. The existing conveyor belts are not equipped with cleaning devices at the bottom, and the conveyor belt and the bottom space are small. Sometimes, in order to ensure the normal operation of the equipment, workers need to be arranged to carry out cleaning operations while the conveyor belt is running, which poses a great safety hazard.

[0003] At the same time, the application number is CN202320123705.7, which discloses "a bucket scraper cleaning machine".

The output mechanism of the hydraulic cylinder is a hydraulic push rod 10. The end of the hydraulic push rod is hinged to the first angle of the triangular rotating block 11, and the second angle of the triangular rotating block is hinged to one end of the upper connecting rod. The third triangular rotation of the triangular rotating block is connected to a roller 12. After the triangular rotating block is flipped, the roller contacts the top surface of the frame to assist the displacement of the cleaning component. A sliding rod 13 that displaces synchronously with the hydraulic push rod is installed above the hydraulic push rod. A limit adjustment switch 14 for controlling the back and forth displacement of the cleaning component is provided on the sliding rod. Bump blocks 15 for touching the front end limit and the rear end limit are also installed at both ends of the sliding rod.

A gap is always maintained between the bottom end of the bucket scraper and the bottom surface of the cleaning trough.

[0023] The principle and use method of an electro-hydraulic bucket scraper sewage discharge and unmanned automatic cleaning device: when the material in the cleaning trough accumulates to a certain height, the hydraulic system is controlled to start the hydraulic cylinder, the hydraulic push rod of the hydraulic cylinder extends, and pushes the upper connecting rod under the connection of the triangular rotating block, and drives the entire cleaning assembly to move horizontally toward the tail funnel. At this time, the upper connecting rod is located at the horizontal rear position of the lower connecting rod, and the bottom of the bucket scraper is in a flat state. Since the friction between the slider in the lower guide assembly and the grooved guide rail is large, and the friction between the upper guide wheel and the top surface of the frame is much smaller than the former, the displacement resistance of the upper connecting rod is much smaller than the lower connecting rod. Therefore, in the process of the hydraulic cylinder pushing the upper connecting rod, the triangular rotating block generates a rotational motion, and the movement of the upper connecting rod drives all the bucket scrapers to flip, so that the bottom of the bucket scraper is in a flat state. In the vertical state, when the bucket scraper moves horizontally toward the tail hopper, the material in the cleaning trough is pushed toward the tail hopper. At this time, the upper connecting rod is located in the horizontal front position of the lower connecting rod until the bumper at the front end of the slide bar touches the front limit, and the entire cleaning assembly stops moving; when the cleaning assembly reaches the front limit, the hydraulic system receives a signal to retract the hydraulic push rod. Similarly, when the hydraulic push rod is pulling the upper connecting rod back, the displacement resistance of the upper connecting rod is much smaller than that of the lower connecting rod, so the triangular rotating block rotates again, and all the bucket scrapers are turned over by the movement of the upper connecting rod, so that the bottom of the bucket scraper is in a flat state, until the bumper at the rear end of the slide bar touches the rear end limit, the entire cleaning assembly stops moving and returns to the starting position, and the above steps are repeated until the material in the cleaning trough is cleaned.

[0024] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
