Description

A mining transfer device Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a mining transfer device. Background Technology

[0002] Mining is the technology and science of extracting mineral resources from within the Earth's crust and on its surface. In a broader sense, mining also includes the extraction of coal and oil. Coal mining is mainly divided into two types: underground mining and open-pit mining. During the operation, ore is usually transported in small batches using transfer devices such as mine cars.

[0003] Utility model patent CN221023807U discloses a mining transfer device, including a transfer platform with a transfer box hinged to it via a support seat. The transfer box has a door on its side, and also includes a buffer protection mechanism and a tilting mechanism. The buffer protection mechanism includes a material support plate fitted inside the transfer box, which is connected to the bottom of the transfer box via an elastic element. A buffer ramp is provided above the material support plate. When coal is being loaded, the weight of the coal presses the material support plate downward. With the cooperation of the support rod, the buffer ramp moves in the opposite direction with the material support plate, expanding the storage space between the material support plate and the buffer ramp, allowing more coal to be poured in. When the transfer box is full of coal, the buffer ramp is pushed to the top of the transfer box, and then two side boxes are pushed towards the middle, so that the two ends of the side boxes abut against the buffer ramp. The cooperation of the buffer ramp and the side boxes can shield the top of the transfer box.

[0004] However, during the transfer process, if the road surface is uneven and the box plate vibrates, the elastic connection system between the material support plate and the buffer inclined plate will cause the buffer inclined plate to dynamically shift. Furthermore, the inclined surface of the buffer inclined plate abuts against the side box plate. During the up-and-down shaking of the buffer inclined plate, horizontal stress will be applied to the side box plate. Under the action of the side box plate's own inertial force, the side box plate will move and misalign, resulting in an opening between the buffer inclined plate and the side box plate. Coal particles are prone to spill out from the opening during transportation. Summary of the Invention

[0005] The technical problem this utility model aims to solve is that: in the existing mining transfer device, openings easily appear between the buffer inclined plate and the side box plate during the transfer process, causing coal particles to spill out from the openings during transportation.

[0006] To solve the above-mentioned technical problems, this utility model provides a mining transfer device, including a bottom plate and a holding box;

[0007] The container has an entrance at the top and an exit at the front, with a door installed at the exit.

[0008] A first driving component is fixed on the rear side wall of the container, and a lifting plate is fixed on the driving end of the first driving component. The left and right sides of the lifting plate are provided with teeth that extend vertically.

[0009] The top of the left and right walls of the container is rotatably mounted with a second shaft. The rear end of each second shaft is provided with a transmission gear that meshes with each tooth. A baffle is fixedly mounted on each second shaft.

[0010] The first driving component is used to drive the lifting plate to rise or fall, thereby driving the two transmission gears to rotate, which in turn drives the sides of the two baffles to move away from each other or to move the sides of the two baffles closer to each other.

[0011] Preferably, the lifting plate is provided with at least one long groove extending vertically, and the rear side wall of the box door is fixed with a stop block corresponding to each long groove. Each stop block is inserted into each long groove, and each long groove moves up and down along each stop block when the lifting plate rises or falls.

[0012] Preferably, there are two long slots.

[0013] Preferably, a second fixing frame is provided at both ends of the top of the left side wall and the top of the right side wall of the container. A second rotating shaft is rotatably installed on the two second fixing frames on the left side wall of the container, and another second rotating shaft is rotatably installed on the two second fixing frames on the right side wall of the container.

[0014] Preferably, the first driving component is a first telescopic cylinder, the base end of the first telescopic cylinder is fixed on the container, and the output shaft of the first telescopic cylinder is fixedly connected to the lifting plate.

[0015] Preferably, the front bottom of the container is rotatably mounted on the base plate, and a second driving component is installed on the base plate. The second driving component is used to drive the container to rotate, so that the outlet of the container door is tilted downward or vertically downward.

[0016] Preferably, a first rotating shaft is fixedly installed at the bottom front end of the container, and two first fixed frames are arranged at left and right intervals on the bottom plate, with the first rotating shaft rotatably mounted on the two first fixed frames.

[0017] Preferably, the second driving component is a second telescopic cylinder, the top of the base plate is provided with a storage groove, a hinge seat is installed in the storage groove, and a connecting frame is fixedly installed at the lower end of the holding box;

[0019] Preferably, the bottom of the base plate is symmetrically provided with several wheels, and a handrail is installed at the rear end of the base plate away from the door.

[0020] Preferably, a control panel is installed on the handrail, and a controller is installed in the control panel. The controller is electrically connected to the first drive component and the second drive component respectively.

[0021] Compared with the prior art, the beneficial effects of this utility model embodiment of a mining transfer device are as follows:

[0022] This utility model provides a mining transfer device, including a base plate and a container. A first driving member is fixed to the rear side wall of the container, and a lifting plate is fixed to the driving end of the first driving member. The lifting plate has vertically extending teeth on both its left and right sides. Second rotating shafts are rotatably mounted on the top of the left and right sides of the container. Each second rotating shaft has a transmission gear at its rear end that meshes with the teeth. A baffle is fixedly mounted on each second rotating shaft. By providing vertically extending teeth on both sides of the lifting plate, which mesh with the transmission gears on the two second rotating shafts respectively, the vertical motion output by the first driving member is converted into a double-sided transmission... The synchronous and reverse rotation of the gears enables the baffles to open and close the inlet of the container. During use, when the first drive unit drives the lifting plate to move vertically up and down, the lifting plate moves the sides of the two baffles away to open the inlet, making it easier for the user to load materials into the container. After loading, the lifting plate is driven to move in the opposite direction to close the inlet. During the transfer process, because the drive end of the first drive unit is fixedly connected to the lifting plate, the position of the lifting plate is fixed by the first drive unit. The teeth on both sides of the lifting plate form a meshing and positioning with the transmission gear. The structure is reliable and avoids the displacement of the baffles due to uneven ground during transportation, thus improving the sealing performance of the transfer device.

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] It should be understood that the terms "first," "second," etc., are used in this invention to describe various types of information, but these terms are not limited to them; they are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0031] As shown in Figures 1 to 4, a preferred embodiment of the present invention provides a mining transfer device, including a base plate 1 and a holding box 3. The top of the holding box 3 has an inlet, and one end of the holding box 3 has an outlet. A door 13 is installed at the outlet. For ease of description of the structure of the mining transfer device of the present invention, the end of the holding box 3 with the door is defined as the front end, the end opposite to the door is defined as the rear end, and the two ends adjacent to the door are the left end and the right end, respectively. Users can load coal and other materials into the holding box through the top inlet. When the outlet at the front end of the holding box is opened, the materials loaded in the holding box can be discharged from the outlet.

[0032] A first driving component is fixed on the rear side wall of the container 3. A lifting plate 9 is fixed to the driving end of the first driving component. The left and right sides of the lifting plate 9 are provided with teeth 12 extending vertically. The top of the left and right sides of the container 3 are rotatably mounted with second rotating shafts 401. The rear end of each second rotating shaft 401 is provided with a transmission gear 6 that meshes with each tooth 12. A baffle 5 is fixedly mounted on each second rotating shaft 401. The first driving component is used to drive the lifting plate 9 to rise or fall, so as to drive the two transmission gears 6 to rotate, thereby driving the sides of the two baffles 5 to move away from each other or to move the sides of the two baffles 5 closer to each other.

[0033] By setting teeth extending vertically on both sides of the lifting plate, which mesh with transmission gears on two second rotating shafts, the vertical motion output by the first driving component is converted into synchronous and opposite rotational motion of the transmission gears on both sides. This enables the baffles to open and close the inlet of the container. During use, when the first driving component drives the lifting plate to move vertically up and down, the lifting plate moves the sides of the two baffles away to open the inlet, making it easier for the user to load materials into the container. After loading, the lifting plate is driven to move in the opposite direction to close the inlet. During the transfer process, because the driving end of the first driving component is fixedly connected to the lifting plate, the position of the lifting plate is fixed by the first driving component. The teeth on both sides of the lifting plate form a meshing and positioning with the transmission gears. The structure is reliable and avoids displacement of the baffles due to uneven ground during transportation, thus improving the sealing performance of the transfer device.

[0034] Specifically, the lifting plate 9 is provided with at least one vertically extending slot 11. The rear side wall of the box door 13 is fixed with a stop block 8 corresponding to each slot 11. Each stop block 8 is inserted into each slot 11. When the lifting plate 9 rises or falls, each slot 11 moves up and down along each stop block 8. Specifically, the end of the container box 3 is fixed with a fixing post 7 corresponding to each slot 11. The end of the fixing post 7 passes through the slot 11. The stop block 8 is fixedly installed at the end of the fixing post 7. The cooperation between the stop block 8 and the slot guides the vertical movement of the lifting plate and eliminates the sway caused by the lateral force of the gear during the lifting process. When the stop block 8 contacts one edge of the slot 11, it can limit the lifting plate to the upper limit position, thereby limiting the maximum opening angle of the two baffles 5. When the stop block 8 contacts the other edge of the slot 11, the edges of the two baffles 5 fit together and close, realizing the complete closure of the entrance and achieving precise control of mechanical limit and action linkage.

[0035] Specifically, there are two long slots 11, which are symmetrically arranged on the lifting plate 9. The two long slots 11 make the force on the lifting plate 9 more even during the lifting process, and further improve the stability of the lifting plate movement.

[0036] Specifically, a second fixing bracket 4 is provided at both ends of the top of the left side wall and the top of the right side wall of the container 3. Each second fixing bracket has a mounting hole at its bottom. Correspondingly, threaded holes aligned with the mounting holes are opened at the top of the left and right side walls of the container 3. Bolts are then passed through the mounting holes on the second fixing brackets and screwed into the threaded holes on the side walls of the container, thereby firmly fixing the second fixing brackets to the top of the side walls. One second rotating shaft 401 is rotatably mounted on the two second fixing brackets 4 on the left side wall of the container 3, and another second rotating shaft 401 is rotatably mounted on the two second fixing brackets 4 on the right side wall of the container 3. Each second fixing bracket is provided with a bearing (such as a rolling bearing or a sliding bearing) to support the smooth rotation of the second rotating shaft 401, thereby making the rotation of the baffle more stable and reliable, and enhancing the load-bearing capacity and vibration resistance of the overall structure.

[0037] Specifically, the first driving component is a first telescopic cylinder 10. The base end of the first telescopic cylinder 10 is fixed on the container 3. The rear side wall of the container 3 is provided with an mounting platform. The base end of the first telescopic cylinder 10 is fixed on the mounting platform. The output shaft of the first telescopic cylinder 10 is fixedly connected to the lifting plate 9.

[0038] When the first telescopic cylinder 10 is not activated, both baffles are in a closed state, with both baffles placed horizontally and their edges touching each other, effectively sealing the inlet of the container 3. During filling, the output shaft of the first telescopic cylinder 10 is extended, causing the lifting plate 9 to rise vertically. The lifting plate, through the meshing of the rack and pinion and the transmission gear, drives the two transmission gears to rotate synchronously in opposite directions, thereby driving the two baffles to open outward around the second axis, realizing the automatic opening of the inlet. After filling is completed, the output shaft of the first telescopic cylinder 10 is retracted, and the lifting plate 9 descends vertically, again driving the transmission gears to rotate synchronously in opposite directions, so that the two baffles are reset and the inlet is closed, completing the entire opening and closing cycle.

[0039] Specifically, the front bottom of the container 3 is rotatably mounted on the base plate 1, and a second driving component is installed on the base plate 1. The second driving component is used to drive the container 3 to rotate, so that the outlet of the opening door 13 is tilted downward or vertically downward, so that the material can be discharged quickly and completely from the outlet of the container.

[0040] Specifically, a first rotating shaft 201 is fixedly installed at the bottom front end of the container 3. Two first fixing brackets 2 are arranged at left and right intervals on the base plate 1. The bottom of each first fixing bracket is provided with mounting holes. Correspondingly, threaded holes aligned with each mounting hole are opened on the base plate. Bolts are then passed through the mounting holes on the first fixing brackets and screwed into the threaded holes on the base plate, thereby firmly fixing the first fixing brackets to the base plate. The first rotating shaft 201 is rotatably mounted on the two first fixing brackets 2. Each first fixing bracket is provided with a bearing (such as a rolling bearing or a sliding bearing) to support the smooth rotation of the first rotating shaft 201, thereby making the rotation of the container more stable and reliable, and enhancing the load-bearing capacity and vibration resistance of the overall structure.

[0041] Specifically, the second driving component is the second telescopic cylinder 16, the top of the base plate 1 is provided with a storage groove 14, a hinge seat 15 is installed in the storage groove 14, and a connecting frame 17 is fixedly installed at the lower end of the container 3; the base end of the second telescopic cylinder 16 is rotatably installed on the hinge seat 15, the output shaft of the second telescopic cylinder 16 is hinged to the connecting frame 17, and a pad block 18 for supporting the container 3 is provided on the base plate 1.

[0042] When unloading is required, the second telescopic cylinder 16 is activated, and its output shaft extends outward, pushing the connecting frame 17 upward. Since the bottom of the outlet end of the container 3 is hinged to the base plate 1 through the first rotating shaft 201, the entire container will tilt forward around the rotating shaft as the rotation center, and the material can be discharged from the outlet of the container. When unloading is completed and reset is required, the output shaft of the second telescopic cylinder 16 retracts, pulling the connecting frame 17 downward, causing the container 3 to rotate in the opposite direction around the first rotating shaft 201 until the bottom of the container falls back onto the pad and returns to the initial horizontal position.

[0043] Specifically, the bottom of the base plate 1 is symmetrically provided with several wheels 19, and a handrail 20 is installed at the rear end of the base plate 1 away from the door 13. The handrail provides a stable point of force for the operator, and the several wheels at the bottom of the base plate enable the entire device to have good mobility.

[0044] Specifically, a control panel 21 is installed on the handrail 20. The control panel 21 contains a controller, which is electrically connected to the first drive component and the second drive component. Operators can conveniently control key actions such as opening and closing the baffle and unloading materials through the control panel, thereby improving the convenience, safety and response efficiency of operation.

[0045] In other embodiments, when the first telescopic cylinder 10 is not activated, the two baffles are in a closed state, both placed horizontally with their edges touching each other, effectively sealing the inlet of the container 3. During filling, the output shaft of the first telescopic cylinder 10 is controlled to retract, causing the lifting plate 9 to descend vertically. The lifting plate, through the meshing of the rack and pinion and the transmission gear, drives the two transmission gears to rotate synchronously in opposite directions, thereby driving the two baffles to open inward around the second axis, realizing the automatic opening of the inlet. After filling is completed, the output shaft of the first telescopic cylinder 10 is controlled to retract, and the lifting plate 9 rises vertically, again driving the transmission gears to rotate synchronously in opposite directions, so that the two baffles reset and close the inlet, completing the entire opening and closing cycle.

[0046] In other embodiments, each first fixing frame is integrally formed on the base plate, and each second fixing frame is integrally formed on the top of the side wall of the container.

[0047] The working process of this utility model is as follows:

[0048] When it is time to load materials into the container, the operator activates the first telescopic cylinder via the control panel on the handrail. The output shaft of the first telescopic cylinder extends, causing the lifting plate to rise vertically. The teeth on both sides of the lifting plate mesh with the transmission gears, causing the two transmission gears to rotate synchronously in opposite directions. This drives the baffles mounted on the second rotating shaft to open outwards, automatically opening the inlet. At this time, the user can load materials such as coal into the container through the top inlet. After loading is complete, the operator retracts the output shaft of the first telescopic cylinder, causing the lifting plate to descend vertically. This again drives the transmission gears to rotate in opposite directions, causing the two baffles to reset and fit tightly together, completing the loading process. The paired inlets are sealed to ensure that materials will not leak during transportation. When unloading is required after the material has been transferred to the designated location, the operator controls the second telescopic cylinder to start via the control panel on the handrail. The output shaft of the second telescopic cylinder extends outward, pushing the connecting frame upward. Since the bottom of the container outlet is hinged to the base plate via the first pivot, the entire container tilts forward around the pivot, allowing the material inside to be discharged smoothly through the outlet. After unloading is completed, the output shaft of the second telescopic cylinder is retracted, pulling the connecting frame downward and causing the container to rotate in the opposite direction around the first pivot, returning to the initial horizontal state, ready for the next operation.

[0049] In summary, this utility model provides a mining transfer device, including a base plate and a container. A first driving member is fixed to the rear side wall of the container, and a lifting plate is fixed to the driving end of the first driving member. The lifting plate has vertically extending teeth on both its left and right sides. Second rotating shafts are rotatably mounted on the top of the left and right sides of the container. Each second rotating shaft has a transmission gear at its rear end that meshes with the teeth. A baffle is fixedly mounted on each second rotating shaft. By providing vertically extending teeth on both sides of the lifting plate, which mesh with the transmission gears on the two second rotating shafts, the vertical motion output by the first driving member is converted into bilateral motion. The synchronous and opposite rotation of the transmission gears enables the baffles to open and close the inlet of the container. During use, when the first drive unit drives the lifting plate to move vertically up and down, the lifting plate moves the sides of the two baffles away to open the inlet, making it easier for the user to load materials into the container. After loading, the drive unit drives the lifting plate to move in the opposite direction to close the inlet. During the transfer process, because the drive end of the first drive unit is fixedly connected to the lifting plate, the position of the lifting plate is fixed by the first drive unit. The teeth on both sides of the lifting plate form a meshing and positioning with the transmission gears. The structure is reliable and avoids displacement of the baffles due to uneven ground during transportation, thus improving the sealing performance of the transfer device.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
