Description

Technical Field

[0001] The present invention relates to the technical field of freight transportation, and particularly to a vertical material taking and loading system. Background Art

[0002] The freight transportation of bulk materials such as coal, ore, and grain is closely related to everyone's life. In the existing railway material handling and loading systems, horizontal conveying equipment (such as belt conveyors, screw conveyors, etc.) is usually used for material conveying and loading. However, these systems have the following problems: 1. Large floor area: Horizontal conveying equipment requires a large installation space, especially in the case of limited space, it is difficult to layout efficiently.

[0003] 2. Low loading efficiency: Traditional loading methods require manual operation or semi-automatic equipment, with slow loading speed and easy material spillage.

[0004] 3. Poor flexibility: The existing systems are difficult to adapt to the changes of different vehicle types and loading heights, resulting in a complex and inefficient loading process.

[0005] 4. High energy consumption: Horizontal conveying equipment has high energy consumption during long-distance conveying, increasing the operating cost.

[0006] Therefore, there is an urgent need for an efficient, flexible and energy-saving vertical material taking and loading system to solve the above problems. Summary of the Invention

A scraper conveyor is arranged in the material storage shed, and the scraper conveyor conveys materials to the bin outlet. A vertical material taking device and a material conveying device are connected to the bin outlet and the scraper conveyor. The vertical material taking device includes a vertical frame, on which a vertically reciprocating rotating vertical chain is arranged. A plurality of tipping hoppers are arranged at intervals on the vertical chain, and the tipping hoppers receive the materials conveyed by the scraper conveyor. The material conveying device includes a conveying frame, in which a conical storage bin is arranged. A weighing platform is arranged at the lower port of the conveying frame, and the weighing platform is used to weigh the parked freight trucks. An inclined downward feeding tube is arranged at the upper end of the vertical frame, and the feeding tube is connected to the conical storage bin of the material conveying device. The plurality of tipping hoppers receiving the materials are successively lifted to the upper end of the vertical frame by the rotating vertical chain and tipped to send the materials to the conical storage bin through the feeding tube. The lower discharge port of the conical storage bin is connected to a distributing machine, and the distributing machine is used to unload and load the materials onto the parked freight trucks on the weighing platform.

[0009] A further solution is: a guide rail is arranged at the lower end of the lower discharge port of the storage bin, and the distributing machine is horizontally and movably arranged at the lower discharge port of the storage bin through the guide rail to achieve uniform front and rear distribution of materials to the freight truck carriage.

[0010] A further solution is: the distributing machine includes a storage box connected to the lower discharge port of the conical storage bin. A chute is arranged on one side of the longitudinal lower end of the storage box, and the chute is a telescopic chute. A scraper conveyor belt is arranged in the storage box, and the scraper conveyor belt is used to send the materials discharged from the conical storage bin into the storage box to the chute and discharge them into the freight truck carriage through the chute.

[0011] A further solution is: the loading process of the distributing machine is as follows: first, sink the outlet of the telescopic chute to the bottom of the carriage, open the chute gate to start loading, and then gradually lift it to the height of the chute outlet and the carriage side board as the materials are discharged from the chute outlet. After the height of the chute outlet is the same as that of the carriage side board, move the distributing machine horizontally backward, and at the same time, continue to keep the chute gate open until the loading is completed.

[0014] The beneficial effects of the present invention are as follows: Compared with traditional loading stations, the present invention adopts the method of "storage bin + belt feeder + truck scale", reducing intermediate batching gates, metering bins, and discharging gates. This not only reduces the spatial size and the number of devices of the loading station, but also enables more accurate metering control to avoid overloading or underloading.

[0015] The system is equipped with vehicle position detection and vehicle type identification.
