Technical Field

[0001] The present application relates to the technical field of coal unloading and transportation by car dumpers, and specifically to an automatic conveying system for residual coal in the car dumper area. Background Art

[0002] Transporting coal by open train is a common mode of transportation, usually used for long-distance and large-volume coal transportation. This method can be achieved by covering the train carriages with tarpaulins with fences or other protective measures to ensure that the coal does not splash or scatter.

[0003] After the coal from the open train is unloaded by the dumper, there is often a small amount of residual coal in the empty carriage. In the empty car cleaning area, the residual coal cleaned manually is usually transported to the coal yard by stacking and secondary transportation by car. The manual work is large, the efficiency is low, and it is not economical. At the same time, there is a lot of dust on site. Summary of the invention

Combined with the equipment layout in the car tipper area, an automated train residual coal cleaning and conveying system is set up next to the empty car line to seal and convey the residual coal manually unloaded from the empty car body to the coal receiving hopper in the car tipper room, thereby eliminating the conventional stacking and secondary transportation operations of the car, reducing a large amount of manual work workload, and effectively solving the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an automatic conveying system for residual coal in the dumper area, including a scraper conveyor 1 and a scraper conveyor 2; also including an equipment groove 1 and an equipment groove 2; scraper conveyor 1 is installed inside the equipment groove 1, and scraper conveyor 2 is installed inside the equipment groove 2, the discharge port of scraper conveyor 1 is connected to the feed port of scraper conveyor 2 through a sealed guide groove, and the discharge port of scraper conveyor 2 is connected to the coal hopper bin.

[0006] The scraper conveyor 2 is installed inside the strip-shaped sealed shell, and a fan is installed on the strip-shaped sealed shell. The gas blown by the fan is blown to the coal hopper bin through the discharge port of the scraper conveyor 2.

[0007] Preferably, ends of the device groove 1 and the device groove 2 are connected together.

[0008] Preferably, the upper surface of the equipment groove one is covered with a steel cover plate and a grille plate, and the grille plate is arranged at the feed inlet of the equipment groove one.

[0009] Preferably, the scraper conveyor comprises a guide groove and a scraper mechanism, the scraper mechanism is arranged around the guide groove, both sides of the upper end of the outer side surface of the guide groove are connected to the inner wall of the equipment groove one through the lower guide plate, and both sides of the upper end of the inner side surface of the equipment groove one are provided with upper guide plates.

[0010] Preferably, the upper guide plate and the lower guide plate are arranged alternately, and the upper end of the lower guide plate is arranged between the upper guide plate and the inner wall of the equipment groove one.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] 1. The automatic conveying system for residual coal in the car dumper area is combined with the equipment layout in the car dumper area. An automatic train residual coal cleaning and conveying system is set up next to the empty car line to convey the residual coal manually unloaded from the empty car body to the coal receiving hopper in the car dumper room in a sealed manner, thus eliminating the conventional stockpiling and secondary car transport operations, reducing a large amount of manual work workload, and at the same time, less dust is raised during the transportation process;

[0013] 2.

[0014] 3. The upper and lower guide plates are staggered. When the dust rises along the lower guide plate, the dust turns around in the gap between the upper and lower guide plates, thereby reducing the rising speed of the airflow, which can effectively reduce the overflow of dust.
