Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and more particularly to the field of mining loaders, specifically a multi-functional mining loader. Background Technology

[0002] A shovel loader is a type of transport machinery that uses a bucket to shovel and load materials for transport. It can perform a comprehensive operation of shoveling, loading, transporting, unloading, layering, and compaction. It is suitable for leveling sites in railway, road, water conservancy, and power engineering projects. Shovel loaders have advantages such as simple operation, no terrain limitations, independent operation, high speed, and high production efficiency. Mine shovel loaders are a type of trackless mining equipment, widely used in underground mining for excavation and transportation. They primarily transport mined ore or rock to the outside using the bucket's space. They can also be used in tunnel construction to transport loose rocks produced after blasting. Currently, the most widely used mine shovel loaders on the market are divided into internal combustion shovel loaders and electric shovel loaders. Internal combustion shovel loaders are suitable for well-ventilated working environments and are flexible and efficient, while electric shovel loaders are more environmentally friendly and pollution-free.

[0003] Mine tunnels are very narrow, and mine loaders can only travel in one lane. When shoveling, loading and transporting materials in confined spaces such as underground mines, traditional loaders often suffer from low work efficiency, complex operation and high safety risks. Traditional loaders usually only have the functions of shoveling and loading materials and need to be used in conjunction with other transportation equipment to complete the entire operation process. This not only increases the operation time, but also increases the number of personnel involved and the risk of operation. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a multi-functional mine shovel and conveyor and its usage method. By integrating the shoveling mechanism and the conveyor bucket, it achieves continuous shoveling and conveying operations, reducing operation time and improving work efficiency.

[0005] This invention is achieved through the following technical solution: providing a multi-functional mine loader and its usage method, comprising a machine body, a lifting base frame connected to the front end of the machine body, an installation box mounted on the lifting base frame, a bucket fixedly connected to the front end of the installation box and mounted on the lifting base frame, the left end of the bucket being hinged to the lifting base frame, the right end of the bucket being connected to the lifting base frame via a lifting cylinder, a door panel hinged to the left side wall of the bucket, a door panel conveyor belt mounted on the door panel, a telescopic conveyor belt connected to the output end of the door panel conveyor belt, the telescopic conveyor belt being installed on the side of the machine body, and the rear of the machine body... A hopper is installed at one end, and a telescopic conveyor belt extends to the hopper. A turntable is rotatably connected inside the mounting box. A raceway ring is provided in front of the turntable. A connecting column fixed on the turntable is slidably connected in the vertical direction inside the raceway ring. A rack extending horizontally is fixed on the raceway ring and slides on the bucket. A gate plate gear is fixed on the gate plate and is connected to the rack gear in a transmission connection. A baffle is connected to the raceway ring through a push rod and slides on the bucket in the horizontal direction. The gate plate is located inside the baffle. The device also includes a drive mechanism that drives the turntable to rotate at intervals. The drive mechanism is installed inside the mounting box.

[0006] This invention utilizes a bucket for material transport. The machine body propels the bucket forward, and the material enters the bucket. The rotation of the turntable causes the raceway ring to move periodically left and right, thereby causing the door panel to open periodically, achieving automated material transport. As the turntable rotates, the connecting column moves with it, performing a circular motion. Relative to the raceway ring, the connecting column's up-and-down movement within the raceway ring pushes the raceway ring left and right, causing the baffle to move. As the baffle pushes outward, the door panel opens to a position perpendicular to the bucket. The bucket tilts, and the material falls onto the door panel. The door panel conveyor belt on the door panel transfers the material to a telescopic conveyor belt, which then transfers the material into the hopper, allowing the loader to transport multiple buckets of material at once.

[0007] As an optimization, the rack and pinion drive is connected to a long shaft rotatably connected to the bucket. The long shaft is connected to an upper shaft via a chain drive. The upper shaft is rotatably connected to the bucket, and an upper shaft gear is fixedly mounted on the upper shaft. This upper shaft gear meshes with a door panel gear. In this optimized configuration, the left and right movement of the raceway ring causes the rack to slide on the bucket. The rack meshes with the gear on the long shaft, thereby causing the long shaft to rotate. The long shaft then drives the upper shaft to rotate via a chain, and the upper shaft, through a gear, drives the door panel shaft to rotate, thus causing the door panel to rotate.

[0008] As an optimization, the drive mechanism includes a rotary motor, a half-gear, and a transmission gear. The rotary motor is installed in a mounting box, the half-gear is fixedly connected to the output shaft of the rotary motor, and the transmission gear is fixedly connected to the turntable, meshing with the half-gear. A sensor is installed on the half-gear, and the sensor is electrically connected to the controller of the lifting cylinder. This optimized design allows the half-gear to periodically drive the transmission gear. When the half-gear rotates to the toothless side, the transmission gear and the half-gear do not drive each other, the baffle is pushed to its left limit, and the baffle acts as a blocking mechanism. The conveyor belt can then transport materials. During this period, the door conveyor belt can transfer materials to the telescopic conveyor belt. When the half-gear rotates to the toothed side, the transmission gear and the half-gear drive each other, the baffle begins to retract, the door begins to close, and the sensor is electrically connected to the controller of the lifting cylinder, enabling the lifting cylinder to operate periodically.

[0009] As an optimization, the door panel includes an upper door panel and a lower door panel. The upper end of the upper door panel and the lower end of the lower door panel are rotatably connected to the bucket. The upper and lower ends of the raceway ring are respectively drivenly connected to the upper and lower door panels. With this optimized design, the door panel is divided into upper and lower door panels, allowing the door panel to open from the middle to the upper and lower sides, reducing the space occupied.

[0010] As an optimization, a conveyor belt is installed on the side of the bucket, and a telescopic conveyor belt is installed inside the conveyor belt. A telescopic plate is slidably connected to the conveyor belt in the front-to-back direction, and the telescopic plate extends to the baffle. With this optimized design, the conveyor belt can prevent materials from falling off the telescopic conveyor belt. When the telescopic conveyor belt extends to below the door panel conveyor belt, the telescopic plate can extend and retract synchronously, protecting the telescopic conveyor belt throughout the entire process and preventing materials from falling off the telescopic conveyor belt.

[0011] As an optimization, the front end of the baffle is connected to a telescopic rod extending in the left-right direction, the right end of which is fixed to the bucket. The rear end of the baffle is fixed to a spare sleeve extending in the left-right direction, and a spring is installed inside the spare sleeve in the left-right direction. The right end of the spring is fixed to a push rod that slides within the spare sleeve, and the push rod extends to the raceway ring and is fixed to it. This optimized design avoids the baffle obstructing the rotation of the door panel. When the door panel is open, if the baffle moves to the left too slowly, the door panel can push the push plate, the spring extends, and temporarily increases the sliding speed of the push plate. When the door panel is closed, if the baffle moves to the left too quickly, the door panel can obstruct the push plate, the spring extends, and temporarily slows down the sliding speed of the push plate.

[0012] As an optimization, a mounting frame is fixedly provided at the rear end of the machine body, and the hopper is hinged to the mounting frame. A lifting cylinder is hinged to the mounting frame, and the output end of the lifting cylinder is hinged to the bottom end face of the hopper. This optimized design allows for convenient emptying of materials from the hopper.

[0013] As an optimization, transmission frames are fixedly connected to both the upper and lower ends of the runway ring, with the transmission frames extending to the rack, and the right end of the rack fixedly connected to the transmission frame. This optimized design allows the runway ring and rack to be fixed together via the transmission frames, enabling the rack to slide in a suitable position.

[0014] As an optimization, a sideboard is installed on the left side of the bucket. The upper end of the sideboard is hinged to a connecting frame via a hinge shaft. A push cylinder is hinged to the upper end of the bucket, and the movable end of the push cylinder is fixedly connected to the connecting frame. A sideboard motor is installed at the upper end of the bucket, and the output shaft of the sideboard motor is fixedly connected to the bottom end of the push cylinder. A hinged motor that drives the hinge shaft to rotate is installed on the connecting frame. With this optimized design, the sideboard can rotate to the outside of the push plate. When the push plate is not in use, it prevents the baffle from sliding. The push cylinder is driven to rotate by the sideboard motor. After the push cylinder rotates to a certain angle, it extends, and the sideboard rotates from a horizontal to a vertical position. The push cylinder then rotates back, and the sideboard provides reinforced protection for the baffle. The sideboard retracts to the upper end of the bucket, reducing the footprint.

[0015] This invention also provides a method of using a multi-functional mine shovel and loader, comprising the following steps: S1: Move the machine body to the required shoveling area, turn on the side plate motor, the side plate motor drives the push cylinder to rotate, and while the push cylinder rotates, the push cylinder extends. When the push cylinder rotates to a set angle, the hinge motor drives the side plate to rotate counterclockwise, and the lower end of the side plate rotates to the inner side of the outer end face of the bucket. The side plate motor and the push cylinder work to reset the push cylinder. At this time, the side plate is placed horizontally on the upper end face of the bucket; S2: The machine body pushes the bucket forward, and the material... The material is pushed into the bucket, and the rotating motor drives the half-gear to rotate. The half-gear periodically engages with the transmission gear. When the half-gear meshes with the transmission gear, the machine body stops moving forward, and the lifting cylinder slowly extends, thus tilting the bucket. S3: During the tilting process, the transmission gear rotates, causing the turntable to rotate, which in turn causes the connecting column to move circumferentially. While the connecting column slides vertically within the raceway ring, it also causes the raceway ring to move horizontally. This causes the raceway ring to move the baffle to the left via the push rod. At the same time, the raceway ring drives... S4: When the rack moves to the left, the transmission drives the gantry to open. At this time, the connecting column on the track ring is at the leftmost end, the half gear and the transmission gear no longer mesh, and the turntable stops rotating; S5: When the bucket begins to tilt, the telescopic conveyor belt extends to below the gantry conveyor belt, and the telescopic plate simultaneously extends and retracts to the baffle. Then the gantry conveyor belt starts, and the material falls onto the gantry conveyor belt. The gantry conveyor belt conveys the material to the telescopic conveyor belt, and the telescopic conveyor belt conveys the material to the hopper; S6: When the half gear and the transmission gear mesh again, the connecting column moves to the right. The raceway ring pulls the baffle back, and at the same time, the raceway ring moves the rack to the right, the door closes, and the lifting cylinder resets. When the half gear and the transmission gear no longer mesh, the machine body can be moved to push the material into the bucket, and the cycle repeats. S6: After the bucket is full of material, the baffle returns to the left side of the bucket, the raceway ring moves to the far right and stops rotating the motor. The bucket is full of stone or coal. The machine body transports the material to the unloading area, the bucket is raised, and the material is poured out. At the same time, the machine body lifts the bucket so that the material in the bucket is poured into the unloading area.

[0016] The beneficial effects of this invention are as follows: This invention can increase the shoveling efficiency of the loader, enabling the loader to transport multiple buckets of material at a time. The material is shoveled into the bucket. When the half-gear meshes with the gear, the bucket is raised and tilted, the baffle and door panel open, and the material falls onto the door panel conveyor belt. The door panel conveyor belt then transfers the material to the telescopic conveyor belt, ultimately bringing the material into the hopper. When the hopper is full, the left side of the bucket can be reinforced and fixed with the side panel before shoveling material into the bucket for transport. This invention can automatically complete the material transfer process. This invention realizes continuous operation of shoveling and transporting, reduces operating time, and improves work efficiency. Attached Figure Description

The rotating wheel 212 and the rear driven shaft are connected through the door panel belt body 211.

[0021] The output end of the door panel conveyor belt 21 is connected to a telescopic conveyor belt 22. The input end of the telescopic conveyor belt 22 is located below the output end of the door panel conveyor belt. The front-to-back width of the telescopic conveyor belt 22 is greater than the width of the door panel conveyor belt 21. The telescopic conveyor belt 22 is installed on the side of the machine body. A hopper 3 is installed at the rear end of the machine body. The telescopic conveyor belt 22 extends to the hopper 3. A mounting frame is fixed at the rear end of the machine body 1. The hopper 3 is hinged to the mounting frame. A lifting cylinder is hinged to the mounting frame. The output end of the lifting cylinder is hinged to the bottom end face of the hopper 3. A conveyor channel 4 is installed on the side end of the bucket. The conveyor channel 4 extends from the rear of the hopper to the top of the hopper 3. The rear end face of the conveyor channel is closed. A discharge port is opened on the end face of the conveyor channel facing the hopper. The telescopic conveyor belt 22 is installed in the conveyor channel. A telescopic plate 23 is slidably connected to the conveyor channel in the front-to-back direction.

[0022] like Figure 7As shown, the telescopic conveyor belt 22 includes a drive wheel 221, a driven wheel 224, a telescopic belt body 225, and a telescopic cylinder 223. A telescopic belt motor is fixedly connected to the inner wall of the conveyor channel 4. The output shaft of the telescopic belt motor is fixedly connected to the drive wheel 221. The drive wheel 221 is connected to the driven wheel 224 through the telescopic belt body 225. A fixing block 222 is mounted on the drive wheel 221 and is rotatably connected to the drive wheel 221.

The connecting post 19 extends in the front-back direction, and the front end face of the connecting post 19 extends to the front of the track ring 18. The connecting post 19 is fixed to the outer periphery of the turntable 20.

[0024] This embodiment also includes a drive mechanism for intermittently rotating the turntable. The drive mechanism is installed in the mounting box 5 and includes a rotating motor, a half-gear 26, and a transmission gear 25. The rotating motor is installed in the mounting box 5 and extends in the front-to-back direction. The half-gear 26 is fixedly connected to the output shaft of the rotating motor, thereby enabling the half-gear 26 to drive the rotating motor. The transmission gear is fixedly connected to the turntable 20 and the rear wall of the turntable. The half-gear has teeth on only one side. When the toothed side rotates to the transmission gear, the transmission gear 25 meshes with the half-gear 26. When the toothed side moves away from the transmission gear, the transmission gear 25 and the half-gear 26 do not drive each other. The diameters of the transmission gear and the half-gear are the same. The ratio of the length of the toothed half-gear to the length of the toothless half-gear is 1:1. A sensor 34 is installed on the half-gear, and the sensor is electrically connected to the controller of the lifting cylinder 7.

[0025] A door panel shaft 214 is fixedly connected to the door panel, extending in the front-to-back direction. The door panel shaft 214 is rotatably connected to the bucket. A door panel gear 215 is fixedly connected to the door panel shaft 214, with one door panel gear 215 at both the front and rear ends. Several racks 28 extending in the left-to-right direction are fixedly connected to the raceway ring. The door panel gears are connected to the racks, thereby drivingly connecting the upper and lower ends of the raceway ring 18 to the upper and lower door panels, respectively. The racks slide on the bucket, and both the upper and lower ends of the bucket are equipped with racks 215. The device has a sandwich structure, with the rack located inside the sandwich structure. The teeth of the rack face inwards. The sandwich structure is provided with a sliding groove for the rack to slide. The upper and lower ends of the track ring are respectively fixedly connected to a transmission frame 27. The rack 28 is fixedly connected to the track ring through the transmission frame 27. The transmission frame extends to the rack 28. The front end of the transmission frame 27 extends to the right side of the rack. The right end face of the rack is fixedly connected to the transmission frame 27. A reinforcing fixing strip is fixedly connected to the left side wall of the front end of the transmission frame. The reinforcing fixing strip is located on the front and rear sides of the rack. The front and rear end faces of the rack are respectively fixedly connected to a reinforcing fixing strip.

[0026] A rack 28 is driven by a long shaft 29 rotatably connected to the bucket. The long shaft 29 extends in the front-to-back direction. A first gear and a second gear are fixedly connected to the long shaft 29. The rack 28 meshes with the first gear and is located above and inside the first gear. The second gear is located in front of the first gear. The long shaft is driven by an upper shaft 31 via a chain 30.

The upper shaft gear meshes with a door plate gear 215 and is located outside the door plate gear.

[0027] A baffle 15 is connected to the runway ring 18. The baffle 15 slides on the bucket 2 in the left-right direction. The door panel 16 is located inside the baffle 15. A telescopic rod 13 extending in the left-right direction is connected to the front end of the baffle. The telescopic rod 13 is existing technology and can play a supporting and guiding role. The telescopic rod includes a bottom cylinder and a first rod that slides in the bottom cylinder. A second rod slides in the first rod, and a third rod slides in the second rod. The right end of the telescopic rod 13 is fixed to the bucket, i.e., the third rod. The right end of the telescopic rod 13 is fixed to the bucket. The bottom cylinder of the telescopic rod 13 slides on the baffle 15 along the left and right sides. The baffle 15 has an opening with the same diameter as the bottom cylinder of the telescopic rod 13. The bottom cylinder of the telescopic rod is located in the opening. Limiting plates are fixed to the left and right sides of the bottom cylinder. The limiting plates can restrict the sliding of the bottom cylinder. The right side of the baffle has a groove to accommodate the limiting plate. When the baffle 15 slides to fit against the right end face of the bucket, the limiting plate enters the groove, thereby preventing the limiting plate from hindering the movement of the baffle.

[0028] A spare sleeve 35 extending in the left-right direction is fixedly connected to the rear end of the baffle 15. The right end face of the spare sleeve is fixedly connected to the left end face of the baffle. The spare sleeve has a central hole. A push rod sliding hole coaxially arranged with the spare sleeve is opened on the baffle. A spring is installed in the spare sleeve 35 in the left-right direction. A push rod 14 that slides in the spare sleeve 35 is fixedly connected to the right end of the spring. The push rod 14 extends in the left-right direction, passes through the baffle and extends to the right side of the baffle. The push rod 14 extends to the runway ring and is fixedly connected to the runway ring.

[0029] The front end of the telescopic plate on the left is provided with an inclined plate extending to the left. When the telescopic plate slides to its maximum stroke, the rear end face of the baffle 15 is in close contact with the front end face of the inclined plate. When the bucket is tilted, the rear end face of the baffle is always within the left and right length range of the inclined plate.

[0030] like Figure 9 As shown, a sideboard 9 is installed on the left side of the bucket 2. A connecting block 32 is fixedly connected to the upper end of the sideboard, and a hinge shaft 33 is fixedly connected to the connecting block. The hinge shaft 33 extends in the front-back direction. A connecting frame 11 is hinged to the upper end of the sideboard through the hinge shaft 33. The connecting frame and the hinge shaft are rotatably connected. A push cylinder 8 is hinged to the upper end of the bucket. The movable end of the push cylinder is fixedly connected to the end of the connecting frame 11 away from the connecting block 32. A sideboard motor is installed at the upper end of the bucket. The output shaft of the sideboard motor is fixedly connected to the bottom end of the push cylinder through a horizontal shaft. The horizontal shaft extends in the front-back direction, and the rear end of the horizontal shaft is fixedly connected to the output shaft of the sideboard motor. The bottom end of the push cylinder is fixedly connected to the horizontal shaft. A hinge motor that drives the hinge shaft 33 to rotate is installed on the connecting frame. The hinge motor is installed on the connecting block.

[0031] In this embodiment, during use, the machine body 1 is moved to the required material-shoveling area, the sideboard motor is turned on, and the sideboard motor drives the push cylinder 8 to rotate. While the push cylinder rotates, it extends to keep the sideboard 9 vertical. When the push cylinder rotates to the set angle, the lower end of the sideboard is above the bucket. The hinge motor drives the sideboard to rotate counterclockwise, and the lower end of the sideboard rotates to the inner side of the outer end face of the bucket 2. The sideboard motor and the push cylinder work to reset the push cylinder. At this time, the sideboard is placed horizontally on the upper end face of the bucket.

[0032] The machine body 1 pushes the bucket 2 forward, and the material is pushed into the bucket. The rotating motor operates, driving the half gear 26 to rotate. The half gear 26 periodically drives the transmission gear. When the half gear 26 meshes with the transmission gear, the sensor 34 detects a signal and transmits the signal back to the machine's control center. The machine body 1 stops moving forward, and the lifting cylinder 7 slowly extends, causing the bucket 2 to tilt. During the tilting process, the transmission gear 25 rotates, driving the turntable 20 to rotate, which in turn drives the connecting column 19 to move circumferentially. While the connecting column slides vertically within the raceway ring 18, it also drives the raceway ring to move horizontally, thereby causing the raceway ring 18 to drive the baffle 15 via the push rod 14. Moving to the left, the track ring 18 simultaneously drives the rack to move to the left via the transmission frame 27. The rack meshes with the first gear on the long shaft 29, thereby driving the long shaft to rotate. The rotation of the long shaft drives the second gear on the long shaft to rotate. The second gear drives the third gear on the upper shaft 31 to rotate via the chain 30. The third gear drives the upper shaft 31 to rotate. The rotation of the upper shaft drives the upper shaft gear to rotate. The upper shaft gear meshes with the door panel gear, thereby driving the door panel to open. Through transmission, the door panel 16 opens. According to customer needs, the transmission ratio between each gear can be different, so that the door panel can be set to different opening and closing angles. At this time, the connecting column 19 on the track ring is located at the leftmost end, the half gear and the transmission gear no longer mesh, and the turntable stops rotating.

[0033] When the door panel 16 is opened, the initial leftward movement speed of the end of the door panel is greater than the leftward movement speed of the baffle 15. At this time, the end of the door panel abuts against the baffle and pushes the baffle to the left. The spring in the retaining sleeve 32 is stretched by force, and the retaining sleeve slides relative to the push rod. The door panel rotates smoothly. As the door panel opens, the leftward movement speed of the end of the door panel gradually decreases. The leftward movement speed of the push rod is greater than the leftward movement speed of the end of the door panel. Finally, the spring contracts and resets, and the outer end face of the door panel 16 fits against the inner end face of the baffle.

[0034] When the sensor detects a signal, the conveyor belt pusher cylinder of the telescopic conveyor belt is activated, pushing the front axle forward and the tension wheel upward to ensure that the belt body fits against the front axle. The telescopic conveyor belt 22 extends to below the door panel conveyor belt 21. At the same time, the conveyor belt pusher cylinder drives the telescopic plate 23 to move forward. The telescopic plate 23 extends and retracts to the baffle 15. The door panel conveyor belt is activated, and the material falls onto the door panel conveyor belt. The door panel conveyor belt conveys the material to the telescopic conveyor belt, which in turn conveys the material to the hopper 3. When the half gear 26 and the transmission gear 25 mesh again, the connecting column moves to the right, the raceway ring drives the baffle 15 to pull back, and at the same time, the raceway ring 18 drives the rack 28 to move to the right, the door panel 16 closes, and the lifting cylinder 7 resets.

[0035] When the door panel 16 is closed, the initial rightward movement speed of the end of the door panel is less than the rightward movement speed of the baffle 15. At this time, the end of the door panel abuts against the baffle, and the door panel obstructs the movement of the baffle. The spring in the spare sleeve 32 is stretched by force, and the spare sleeve slides relative to the push rod. As the door panel closes, the leftward movement speed of the end of the door panel gradually increases, and the rightward movement speed of the push rod is less than the rightward movement speed of the end of the door panel. Finally, the spring contracts and resets, the door panel closes, and the right end face of the baffle is in contact with the outer end face of the right wall of the bucket.

[0036] When the half gear 26 and the transmission gear 25 no longer mesh, the sensor senses the signal and transmits it to the machine body. The movable machine body pushes the material into the bucket. This process repeats until the bucket 3 is full of material. Then, the side panel returns to the left side of the bucket, the raceway ring moves to the far right, and the rotating motor 17 stops operating. The bucket is full of stones or coal. The machine body transports the material to the unloading area, the bucket is raised, and the material is poured out. At the same time, the machine body lifts the bucket, causing the material in the bucket to be poured into the unloading area.
