Description

Technical Field

[0001] The invention relates to the technical field of coal loading, in particular to a coal loading system and a loading method thereof. Background Art

[0002] With the increase in mine production and the strengthening of safety and security management, the efficiency of local sales shipments has become one of the factors restricting mine production. The traditional form of local sales coal transportation is loaded by engineering vehicles, which is not only inefficient and labor-intensive, but also poses a great hidden danger to the safety management of coal yards, which brings limitations and bottlenecks to the shipment of local sales coal, seriously restricting the shipment of local sales coal in mines.

[0003] At present, most mines have seen a significant reduction in labor force due to objective factors such as retirement of employees, internal retirement, lack of new employees and increasing age "aging". However, the shipment of local coal requires more manpower, and the two are in conflict, resulting in the impact on the shipment of local coal.

[0004] The comparative document publication number CN201510284735.6 discloses a coal distribution device; the coal is separated into fine clean coal, lump clean coal and coking coal through an outside loading chute, a coal feeder and a coal jig sorter, and the three types of coal are transported by a first belt, a second belt and a third belt respectively, and the items transported by the first belt and the second belt are directly loaded and transported at the end of the belt; the comparative document does not disclose how the coal is transported to the loading vehicle by the belt, and only uses the traditional loading method, which requires a lot of labor.

[0007] Personnel only need to operate the loading car and control the start and close of the cylinder to load the coal through the coordination of knife switches and belt transportation, which reduces the large amount of manpower required for traditional loading methods and improves loading efficiency.

[0008] Preferably, the linkage assembly includes a 7-shaped linkage rod, a connecting rod, and a linkage plate; the 7-shaped linkage rod includes a cross bar at the top and a vertical bar at the bottom; the vertical bar is fixed to the bottom of one end of the cross bar away from the knife switch; the knife switch is fixed to the other end of the cross bar; the cylinder is fixed to the cylinder bracket; the cylinder bracket is fixed to the ground; the output end of the cylinder is movably connected to the end of the cross bar facing the knife switch through a hinge seat; a connecting rod extending toward the guide roller mounting plate is fixed to one end of the cylinder bracket; the rod body of the vertical rod is rotatably connected to the connecting rod through a hinge shaft; the bottom end of the vertical rod is rotatably connected to the linkage plate through a hinge shaft; the other end of the linkage plate is rotatably connected to the guide roller mounting plate through a hinge shaft.

[0010] Preferably, after the guide roller mounting plate is lowered to the lowest position, the cross-section of the belt is U-shaped.

[0011] Preferably, the output end of the cylinder is arranged obliquely toward the belt.

[0012] Preferably, with the belt advancing direction as the normal direction, the knife gate and the belt are arranged at an angle of 5-15 degrees in the transverse direction, and the funnel is arranged below the side where the knife gate body forms an obtuse angle with the normal.

[0016] A loading method of a coal loading system comprises the following steps:

[0017] S1 starts the cylinder to drive the linkage components to work;

[0018] One output end of the S2 linkage assembly drives the knife gate to descend, and the other output end pulls the guide roller mounting plate to rotate around the hinge point on the support seat. The guide roller mounting plate rises, driving the guide roller to rise, and the belt on the guide roller rises until the belt surface fits the knife gate;

[0019] The S3 belt transports coal, which is intercepted by the knife gate and directed into a hopper on one side, and then flows from the hopper into the loading vehicle.

Under the limiting action of the hinge rod, the guide roller mounting plate makes an arc motion upward and toward the vertical bar at the hinge point between the hinge rod and the support platform, that is, the guide roller mounting plate is raised, and the guide roller is driven up to lift the belt on the guide roller until it fits tightly with the knife gate. The coal transported on the belt is intercepted by the knife gate at the knife gate position and directed to a pre-prepared funnel on one side, and then led from the funnel to the loading car; the personnel only need to operate the loading car and control the start and close of the cylinder, and realize the loading of coal through the coordination of the knife gate and the belt transportation, which reduces the large amount of manpower required for traditional loading methods and improves the loading efficiency; during the time period of opening and closing the cylinder, the personnel can control the amount of loaded coal by observing the weight displayed on the belt electronic scale, reduce the errors caused by manual loading, and avoid overloading or underloading of the loading car; finally, the whole process requires very few operators, which greatly improves the safety of coal loading in the mine.
