DETAILED DESCRIPTION
[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0038] See also Figures 1 to 4 In this embodiment, a coal mine feeding buffer receiving device includes a buffer bucket 1, a feed port 2, a discharge port 3 and two baffles 4. The feed port 2 is opened above the buffer bucket 1, and the discharge port 3 is opened below the buffer bucket 1. The two baffles 4 are respectively arranged on the left and right sides of the feed port 2. The two baffles 4 are both inclined, and the two baffles 4 are inclined in opposite directions, which makes it easy to use the baffles 4 to guide the coal mine so that the material is concentrated as much as possible in the center of the buffer bucket 1. The side edges of the two baffles 4 are in contact with the inner wall of the buffer bucket 1, and the surface of the baffles 4 is installed with rubber pads, which can protect the surface of the baffles 4 and reduce the impact of buffering.
[0039] Buffer assemblies 5 are provided on both the left and right sides of the buffer bucket 1. The buffer assemblies 5 are used to support and buffer the baffle 4. The buffer assembly 5 includes a slide rail 501, a slider 502, a connecting plate 503, a connecting shaft 504, a connecting seat 505, a buffer rod 506, a fixed plate 507, a movable plate 508, a first spring 509, and a limit rod 510.
[0040] Among them, the slide rail 501 is fixedly connected to the inner and outer walls of the buffer bucket 1, the slider 502 is slidably connected to the inner wall of the slide rail 501, both ends of the connecting plate 503 are fixedly connected to the opposite side of the slider 502, the connecting shaft 504 is fixedly connected to the inside of the connecting plate 503, and its two ends pass through and extend to the outside of the connecting plate 503. The inside of the connecting seat 505 is rotatably connected to the two ends of the connecting shaft 504, and the surface of the connecting seat 505 is fixedly connected to the baffle 4. The buffer rod 506 is located between the slider 502 and the baffle 4 and is fixedly connected to the surface of the slider 502. The buffer rod 506 is a rubber rod, and the buffer The surface of the punch rod 506 fits with the baffle 4. When the baffle 4 rotates, the buffer rod 506 can buffer the baffle 4. The fixed plate 507 is fixedly connected to the surface of the buffer bucket 1 and is located below the slide rail 501. The movable plate 508 is fixedly connected to the surface of the slider 502. The movable plate 508 is parallel to the fixed plate 507. The two ends of the first spring 509 are fixedly connected to the movable plate 508 and the fixed plate 507 respectively. The limiting rod 510 is fixedly connected to the bottom of the movable plate 508 and is located inside the first spring 509. The bottom end of the limiting rod 510 passes through and extends to the bottom of the fixed plate 507.
[0041] When the coal falls, it will hit the baffle 4. When the baffle 4 is impacted, the slider 502 slides in the slide rail 501, driving the movable plate 508 to move. A first spring 509 is installed between the movable plate 508 and the fixed plate 507, so that the first spring 509 can be used to buffer the downward impact force exerted on the baffle 4. Since the connecting seat 505 is rotatably connected to the connecting shaft 504, the buffer rod 506 is located between the slider 502 and the baffle 4, which can effectively buffer the rotation of the baffle 4. Therefore, when the coal material falls, the cooperation of the first spring 509 and the buffer rod 506 can effectively reduce the impact of the falling coal.
[0042] An auxiliary material discharge component 6 is provided inside the buffer hopper 1, and the auxiliary material discharge component 6 is used to divert and buffer the material. The auxiliary unloading assembly 6 includes a bracket 601, a support plate 602, a bottom cylinder 603, a second spring 604, a buffer plate 605, a dividing plate 606 and a sleeve 607, wherein the two ends of the bracket 601 are fixedly connected to the inner wall of the feed hopper, the bottom of the support plate 602 is fixedly connected to the surface of the bracket 601, the bottom end of the bottom cylinder 603 is fixedly connected to the top of the support plate 602, and the sleeve 607 is movably connected to the outer surface of the bottom cylinder 603. The two ends of the second spring 604 are respectively fixedly connected to the inner wall of the sleeve 607 and the top of the support plate 602, the bottom of the buffer plate 605 is fixedly connected to the top of the sleeve 607, and there are several dividing plates 606, which are evenly distributed on the surface of the buffer plate 605 and fixedly connected to the buffer plate 605. The buffer plate 605 is in an inverted V shape, and the bending part of the buffer plate 605 is fixedly connected to the sleeve 607, so that the coal can be diverted when it falls onto the buffer plate 605.
[0043] The coal falls along the baffle 4 onto the buffer plate 605. Since a second spring 604 is installed between the bottom cylinder 603 and the sleeve 607, the second spring 604 can play a buffering role, and when the material falls onto the buffer plate 605, the coal will be diverted and fall along the distribution gap of the dividing plate 606. The function of the dividing plate 606 prevents the coal from falling along the inclined surface of the buffer plate 605 with acceleration and impacting the inner wall of the buffer bucket 1.
[0044] The working principle of the above embodiment is:
[0045] The buffer bucket 1 is set above the conveyor belt, and the coal enters the buffer bucket 1 through the feed port 2 of the buffer bucket 1. When the baffle 4 is impacted, the slider 502 slides in the slide rail 501, driving the movable plate 508 to move. A first spring 509 is installed between the movable plate 508 and the fixed plate 507, so that the first spring 509 can be used to buffer the downward impact force exerted on the baffle 4. Moreover, since the connecting seat 505 is rotatably connected to the connecting shaft 504, the buffer rod 506 is located between the slider 502 and the baffle 4, which can effectively buffer the rotation of the baffle 4. Therefore, the coal material falls, and the cooperation of the first spring 509 and the buffer rod 506 can effectively reduce the impact of the falling coal. The coal falls along the baffle 4 onto the buffer plate 605, and the second spring 604 can play a buffering role. When the material falls on the buffer plate 605, the coal will be diverted and fall along the distribution gap of the dividing plate 606. The function of the dividing plate 606 prevents the coal from falling along the inclined acceleration of the buffer plate 605 and impacting the inner wall of the buffer bucket 1, which greatly slows down the falling speed of the coal, thereby indirectly reducing the impact force of the coal discharge, playing a role in material discharge buffering, and effectively improving the service life of the conveyor belt.
