Description
Technical field:
[0001] The utility model relates to the technical field of warehouse unloading, in particular to a multi-point unloading chute. Background technology:
[0002] In underground coal mining and transportation, there are a lot of gangue and debris mixed in the raw coal, and the impurities in the raw coal need to be sorted out by screening and washing. First, the raw coal is transported to the pre-grading screen for grading, and the screened material directly enters the washing system for processing, and the screened material enters the belt conveyor for impurity removal and crushing, and then enters the washing system for processing; then, the large pieces of gangue and debris entering the belt conveyor are sorted manually, and the sorted gangue and debris slide freely into the warehouse through the inclined unloading chute. At present, the unloading chute uses a unloading pipe with only one drop port, and the drop is concentrated. When the gangue and debris accumulate to a certain extent, a loader is required to transport the accumulated gangue and debris to other locations in the warehouse or load them on trucks for transportation, which cannot effectively utilize the storage space of the warehouse and increases transportation costs. Utility model content:
[0003] The utility model aims to provide a multi-point unloading chute.
[0004] The purpose of the utility model is implemented by the following technical scheme: a multi-point unloading chute, which includes a first chute, a second chute, a guide plate, a V-shaped unloader, a baffle plate and a unloading plate; the guide plate is horizontally connected between the first chute and the second chute, one end of the guide plate is connected to the bottom plate of the first chute, and the other end of the guide plate is connected to the bottom plate of the second chute; the V-shaped unloader is installed on the guide plate, the tip of the V-shaped unloader is placed in the first chute and is arranged toward the feed port of the first chute, the baffle ends of the V-shaped unloader extend from both sides of the guide plate respectively, and the baffle plate vertically arranged on the plate surface is connected below the baffle of the V-shaped unloader; the unloading plate is slidably connected along the length direction below the bottom plate on the discharge side of the second chute.
[0005] Preferably, the V-shaped unloader includes a fixed frame, a reinforcement beam, a telescopic cylinder and two baffles; the fixed frame is installed above the middle of the second chute, and the fixed frame is arranged perpendicular to the length direction of the second chute; the two baffles are connected to form a V-shaped structure, the tip of the V-shaped structure is placed in the first chute and is arranged toward the feed port of the first chute, and the reinforcement beam is provided in the V-shaped structure along the length direction of the second chute, and one end of the reinforcement beam is fixedly connected to the inner side of the tip of the V-shaped structure; the telescopic end of the telescopic cylinder is fixed on the reinforcement beam, and the cylinder body of the telescopic cylinder is hinged on the fixed frame.
[0006] Preferably, a U-shaped plate is further provided inside the V-shaped structure. The other end of the reinforcing beam is vertically arranged and fixedly connected to the main plate of the U-shaped plate. The two side plates of the U-shaped plate are respectively hinged to the side walls of the second chute through fixing pins.
[0007] Preferably, L-shaped chutes are respectively fixed on both sides of the outer surface of the bottom plate of the second chute along the length direction. The two L-shaped chutes are arranged oppositely. Both sides of the discharge plate are slidably inserted into the corresponding L-shaped chutes. A gear is fixed on the outer surface of the bottom plate of the discharge side of the second chute. The gear is driven by a motor. A rack is fixed on the upper surface of the bottom plate of the discharge plate along the length direction. The rack is engaged with the gear.
[0008] Preferably, the longitudinal cross-sections of the first chute and the second chute are both in a "U" shape.
[0009] Advantages of the present invention: In the present invention, the tip of the V-shaped discharger is lowered. The gangue and sundries after manual sorting enter from the feed port of the first chute, flow along the baffle forming the V-shaped structure, and are discharged from the discharge port of the first chute. This is the first material dropping point. The tip of the V-shaped discharger is lifted. The tip of the V-shaped discharger is far away from the bottom surface of the first chute. The baffle drives the baffle plate to move upward. The baffle plate covers the discharge port of the first chute to prevent the gangue and sundries from continuing to be discharged from the discharge port of the first chute. When the tip of the V-shaped structure is lifted, the first chute is communicated with the second chute. The gangue and sundries enter the second chute and are discharged from the discharge port of the second chute. This is the second material dropping point. The motor is controlled to drive the gear to rotate, driving the rack to move linearly. The rack drives the discharge plate to move relative to the second chute. When the discharge plate slides out relative to the second chute, the gangue and sundries enter the discharge plate from the discharge port of the second chute and fall along the periphery of the discharge plate. This is the third material dropping point. In addition, the extension distance of the discharge plate relative to the second chute can be flexibly adjusted according to the dropping point of the gangue and sundries. Therefore, different material dropping points can be provided through the first chute, the second chute and the discharge plate, and the gangue and sundries can be piled up at different positions in the warehouse, effectively utilizing the storage space of the warehouse and reducing the transportation cost.
