Description

Technical Field

[0001] The present invention relates to the technical field of unloading, and in particular to a mine scraper unloading device. Background Art

[0002] A scraper is a type of earth-moving and transporting machinery that uses a bucket to shovel soil and loads the crushed soil into the bucket for transportation. It can complete the comprehensive operations of shoveling, loading, transporting, unloading, layered filling, and local compaction. It is suitable for leveling sites in railway, road, water conservancy, electric power and other projects. In mining projects, scrapers are widely used in shoveling, transporting, and unloading materials. Mining scrapers are often short and long, and their lifting height is limited. When unloading ore onto transport vehicles, they need to use conventional scrapers or other machinery.

[0003] The invention patent with announcement number CN115783813B discloses an automatic unloading device for a mine shovel loader, which utilizes the height of the track to realize the lifting and lowering of the carrying device, and utilizes the flexibility of the rope to realize the free swinging of the loading box, which can reduce the complexity of the device, simplify the handling steps, and improve work efficiency. However, this invention patent also has the following problems: since it is connected to the loading box by ropes, multiple ropes all point to the upper position of the top center of the loading box, so that the space on the top of the loading box for the loader to unload is small. For example, the movement to the left and right sides of the forward direction of the shovel loader will be restricted, making the unloading operation of the shovel loader more difficult. Secondly, the unloaded materials are concentrated in part of the loading box, so that the materials are accumulated in one area, resulting in reduced utilization of the internal space of the loading box.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0028] like Figures 1 to 6 As shown, the present invention provides a mining shovel loader unloading device, including a bracket 1 and two movable rails 2 symmetrically arranged on the bracket 1, and the two movable rails 2 are arranged in parallel at the same height, each of the movable rails 2 is provided with a moving device 3, and the moving device 3 can move along the moving rail 2, each of the movable devices 3 is provided with a first lifting device 9, each of the first lifting devices 9 is connected to a carrying bucket 4 whose bottom can be automatically opened and closed through a plurality of connecting ropes, and each of the first lifting devices 9 coincides with the center line of the corresponding carrying bucket 4 in the vertical direction, and each of the first lifting devices 9 is provided with a flaring structure 5 at the bottom, and the flaring structure 5 is used to externally support a plurality of connecting ropes, and a stabilizing device 6 connected to the bracket 1 is provided on the outside of each carrying bucket 4, and two telescopic guide structures 7 are provided on the bracket 1, and each of the telescopic guide structures 7 can rotate around a horizontal straight line and guide the shovel loader to the unloading position in the carrying bucket 4.

[0029] When the present application is in use, the shovel loader moves to the telescopic guide structure 7 and dumps the material onto the telescopic guide structure 7 from the top of the telescopic guide structure 7. The telescopic guide structure 7 first extends to the position farthest from the shovel loader in the carrying bucket 4, so that the material is loaded from the side of the carrying bucket 4 away from the shovel loader. Then the telescopic guide structure 7 gradually moves from the position away from the shovel loader in the carrying bucket 4 to the position close to the shovel loader, so that the dumped material is evenly distributed in the carrying bucket 4, avoiding the accumulation of material in a single area in the carrying bucket 4, thereby improving the space utilization in the carrying bucket 4. The telescopic guide structure 7 can be rotated to adjust the angle of material dumping to ensure that the material can be completely dumped into the carrying bucket 4.

[0030] When the carrying bucket 4 is fully loaded with materials, the telescopic guide structure 7 detaches from the carrying bucket 4, and then the moving device 3 moves along the moving track 2 to drive the carrying bucket 4 to move to the unloading area. When the carrying bucket 4 reaches the unloading area, the first lifting device 9 controls the carrying bucket 4 to move downward to an appropriate position, such as an appropriate height above the transport vehicle, and then the carrying bucket 4 opens the bottom to unload. After filling the transport vehicle, it is then moved to the initial position through the moving device 3 for loading, and the above actions are repeated in a cycle.

[0031] The stabilizing device 6 is used to stabilize the carrying bucket 4 after loading, to prevent the carrying bucket 4 from shaking due to movement and change of center of gravity.

[0032] The arrangement of the two moving rails 2, the two moving devices 3 and the two carrying buckets 4 enables the material unloading process to proceed continuously, thus ensuring the unloading effect.

[0033] In this embodiment, the moving track 2, the moving device 3, the carrying bucket 4 and the first lifting device 9 are all existing technologies. The moving device 3 can move along the moving track 2, such as by being driven by a screw or other means. The bottom of the carrying bucket 4 can automatically open and close to be closed and opened, and the first lifting device 9 controls the up and down movement of the carrying bucket 4. The above devices are all functions that can be realized by existing technologies. For example, the first lifting device 9 can be a motor driving two mutually meshing gears to rotate, one of which is threadedly connected to the screw, and the bottom of the screw is rotated to connect to the rotating plate, and multiple connecting ropes are connected to the circumferential side of the rotating plate, or other technical solutions are all possible. The technical principles of the moving track 2, the moving device 3, the carrying bucket 4 and the first lifting device 9 are not elaborated in detail here.

[0034] The flaring structure 5 includes a connecting rod 501 vertically arranged at the bottom of the first lifting device 9, an outward expansion plate 502 is provided at the bottom of the connecting rod 501, and a plurality of first guide rail rollers 503 are rotatably provided on the circumferential side of the outward expansion plate 502. Two side plates extend outward from the top of the carrying bucket 4, and a plurality of second guide rail rollers 504 are rotatably provided on each side plate. Each connecting rope passes through the corresponding first guide rail roller 503 and second guide rail roller 504 in turn.

[0035] Since the carrying bucket 4 is connected to the first lifting device 9 through a connecting rope, the farther away from the carrying bucket 4 in the vertical direction, the smaller the space between the multiple connecting ropes. The space between the multiple connecting ropes is expanded by setting an outer expansion plate 502, and the space between the multiple connecting ropes is expanded by the side plate to ensure that the telescopic guide structure 7 has enough space to enter the interior of the carrying bucket 4 from above the carrying bucket 4, and to ensure that the material has enough space to enter the carrying bucket 4, thereby avoiding the problem of the carrying bucket 4 shaking and the connecting rope breaking due to contact between the material and the connecting rope.

[0036] The connecting rope is guided by the first guide roller 503 and the second guide roller 504 to reduce wear of the connecting rope during use.

[0037] On a horizontal plane, the distance between the first guide roller 503 and the center of the carrying bucket 4 is smaller than the distance between the second guide roller 504 and the center of the carrying bucket 4. This ensures that the pulling force of the multiple connecting ropes on the carrying bucket 4 is directed upward from the center of the carrying bucket 4, thereby ensuring the stability of the carrying bucket 4 during use.

[0038] The stabilizing device 6 includes a stabilizing plate 601 arranged on the bracket 1, and the stabilizing plate 601 is located between the two movable rails 2 and perpendicular to the horizontal plane. A plurality of avoidance grooves 605 are provided on the stabilizing plate 601. The two opposite sides of the stabilizing plate 601 are slidably connected with groove plates 602, and the movement direction of each groove plate 602 is perpendicular to the horizontal plane. Each groove plate 602 is provided with a slide groove 603, and a slide plate 604 is provided on one side of each carrying bucket 4, and the end of each slide plate 604 is slidably connected to the corresponding slide groove 603.

[0039] When the carrying bucket 4 slides in the horizontal direction, the carrying bucket 4 drives the slide plate 604 to slide along the slide groove 603, and the slide groove 603 limits the slide plate 604 from flipping around the horizontal straight line, thereby limiting the flipping of the carrying bucket 4, thereby ensuring the stability of the carrying bucket 4 during movement.

[0040] When the first lifting device 9 drives the carrying bucket 4 to move up and down, it can drive the slide plate 604 to move up and down, and drive the groove plate 602 to move up and down through the cooperative connection between the slide plate 604 and the slide groove 603.

[0041] The telescopic guide structure 7 includes a rotating device 701 arranged on the bracket 1, a connecting seat 702 is provided on the rotating device 701, a telescopic device 703 is provided on the connecting seat 702, a guide plate 704 is provided at the movable end of the telescopic device 703, and the guide plate 704 is inserted into the carrying bucket 4 at an angle.

[0042] The rotating device 701 drives the connecting seat 702 to rotate to adjust the angle of the guide plate 704 in the telescopic carrying bucket 4, and assists in unloading by reciprocating the guide plate 704.

[0043] The telescopic device 703 drives the guide plate 704 to extend into the carrying bucket 4, so that the material unloaded by the shovel loader falls into the carrying bucket 4, and the telescopic device 703 drives the guide plate 704 to move, so that the bottom of the guide plate 704 gradually moves in a straight line direction close to the unloading position of the shovel loader, thereby guiding the material to fall evenly into the carrying bucket 4, so as to avoid wasting space in the carrying bucket 4, improve space utilization, and prevent the center of gravity of the carrying bucket 4 from deviating too much from its center after loading the material.

[0044] A plurality of buffer plates 705 are obliquely provided on one side of the guide plate 704 , and the plurality of buffer plates 705 are arranged in a wave shape, and the upper surface of each buffer plate 705 is an inclined surface.

[0045] When the material falls along the guide plate 704, it first contacts the first buffer plate 705 and slides along the first buffer plate 705 until it falls on the second buffer plate 705. Since the multiple buffer plates 705 are distributed in a wave shape, the surface of the second buffer plate 705 can block the falling material, reducing the kinetic energy of the falling material, thereby achieving a buffering effect and reducing the impact of the material on the carrying bucket 4. The inclined design of each buffer plate 705 can prevent the material from accumulating on the surface of the buffer plate 705, so that the material can slide along the buffer plate 705 and can also slide directly into the carrying bucket 4 along the top of the guide plate 704, ensuring smooth material unloading.

[0046] A support structure 8 is provided on the bracket 1, and the support structure 8 includes a support base 801 provided on the bracket 1, and a support groove 802 rotatably connected to the connecting base 702 is provided on one side of the support base 801, and an extension plate 803 is provided on one side of the support base 801, and a second lifting device 804 is provided on the extension plate 803, and the top of the second lifting device 804 is rotatably connected to a support plate 805 that is in sliding contact with the bottom of the guide plate 704, wherein the connecting base 702 is semi-cylindrical.

[0047] The connecting seat 702 is supported by the inner side wall of the support groove 802 to ensure the stability of the connecting seat 702 when in use. The second lifting device 804 supports the guide plate 704 by abutting against the bottom of the guide plate 704 through the support plate 805, thereby supporting the guide plate 704 and ensuring the stability of the guide plate 704 when in use.

[0048] A rotating device 806 is provided at the bottom of the support plate 805 , and a striking ball 807 is connected to the rotating device 806 via an elastic rod.

[0049] The elastic rod is driven by the rotating device 806 to drive the knocking ball 807 to rotate, thereby continuously knocking the guide plate 704 to assist the material to slide down on the guide plate 704.

[0050] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
