Description

Technical Field

[0001] The present application relates to the technical field of bulk material conveying, and in particular to a mobile bulk material stacker. Background Art

[0002] Bulk material stacker is a mechanical equipment used to handle and move bulk materials. It is widely used in various industrial fields, such as ports, metallurgy, mining, power and coal chemical industry. Bulk material stacker usually moves bulk materials from one place to another through a mechanical arm or conveyor belt system. Its core function is to realize the stacking and retrieval of materials. According to the specific application requirements, the stacker is divided into fixed or mobile types.

[0003] Most of the existing mobile bulk material stackers directly install a set of wheels on the lower surface of a high-lift belt conveyor, so that the high-lift belt conveyor has the function of walking. However, when using this conveyor, the dump truck needs to tilt the material to the ground, and then use a forklift to shovel the material on the ground to the high-lift belt conveyor, which then transports the material to a high place and throws it down. Therefore, its stacking efficiency is extremely low and cannot meet the needs of rapid stacking. In addition, during the stacking process, the material is seriously spilled, which is very troublesome to sort out later. Summary of the invention

[0004] The present application provides a mobile bulk material stacker, on which a dump truck can directly dump materials, effectively avoiding the spillage of materials, and can quickly and efficiently transport materials to a high place for stacking, effectively improving the stacking efficiency of materials and effectively solving the problems in the background technology.

[0014] Preferably, the conveyor support is fixed to the outer side of the base through a connecting rod, and at least one hydraulic telescopic rod three is installed on the outer side of the conveyor support, and a universal wheel two is installed at the telescopic end of the hydraulic telescopic rod three.

[0015] Preferably, the stacking conveyor includes a conveyor bracket, and a high-angle belt conveyor is installed on the upper surface of the conveyor bracket.

When a feature is referred to as being "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0022] See also Figure 1-7 The present application provides the following technical solution: A mobile bulk material stacker includes a base 3. The left end of the upper surface of the base 3 is a parking platform 6, the right end of the upper surface of the base 3 is a grid mesh plate 5, and the outer side surface of the base 3 is rotatably connected to the left and right sides with a slope 1.

[0023] Specifically, by providing two slopes 1, the left and right sides of the grille mesh plate 5 can be turned over and unloaded synchronously, which effectively improves the efficiency of unloading and stacking.

[0024] The lower surface of the grid mesh plate 5 is paved with a plurality of parallel longitudinal conveyors 31, and a stacking conveyor 7 is arranged at the rear end of the lower surface of the longitudinal conveyor 31. At least one longitudinal walking mechanism is installed at the edge of the outer side surface of the base 3, and a hydraulic lifting device is installed on the longitudinal walking mechanism.

[0025] Specifically, the material falling through the mesh holes of the grid mesh plate 5 first falls onto the upper surface of the longitudinal conveyor 31, and then the longitudinal conveyor 31 conveys the material to the upper surface of the stacking conveyor 7, and then the stacking conveyor 7 transports the material to the stacking position and stacks it together.

[0026] A plurality of height-adjustable support devices are evenly arranged at both ends of the outer side surface of the base 3. The lower surface of the base 3 is rotatably connected to a plurality of transverse walking mechanisms, and the transverse walking mechanisms include an X-axis 29, which is rotatably connected to the base 3. A walking roller 2 30 is provided in the middle of the outer side surface of the X-axis 29. An X-axis walking motor 28 is installed on the lower surface of the base 3, and the output shaft of the X-axis walking motor 28 is connected to the X-axis 29.

[0027] Specifically, when the ground is uneven, the support legs can be adjusted by the support device so that the base 3 is always in a horizontal state. The transverse walking mechanism is used to drive the entire device to move left and right, and the longitudinal walking mechanism is used to drive the entire device to move forward and backward. The longitudinal walking mechanism is installed with a lifting device, and it is placed on the ground only when it needs to be used.

[0028] More specifically, the parking platform 6 and the grille mesh 5 are welded to the upper surface of the base 3. The base 3 is a bracket welded from steel sections. The ramp 1 is installed on the upper end of the outer surface of the base 3 through a hinge support. Both ends of the X-axis 29 are installed on the lower surface of the base 3 through bearing seats. The output shaft of the X-axis travel motor 28 is connected to the X-axis 29 through a coupling.

[0029] A blocking rod 4 is provided on the upper surface of the parking platform 6 near the grille mesh 5. The blocking rod 4 is used to prevent the transport vehicle from entering the upper surface of the grille mesh 5. When the transport vehicle dumps materials, most of the materials fall directly on the grille mesh 5, which can effectively reduce the impact of the materials on the longitudinal conveyor 31 during the falling process. At the same time, the mesh holes of the grille mesh 5 can effectively reduce the falling speed of the materials, avoiding the direct accumulation of materials on the upper surface of the longitudinal conveyor 31.

[0030] Furthermore, the upper surface of the slope 1 is paved with an anti-slip grid plate 2 .

[0031] Specifically, the setting of the anti-skid grating plate 2 can not only play a good anti-skid effect, but also can drain the bulk material dropped on its upper surface to the bottom of the anti-skid grating plate 2, which can effectively prevent the bulk material dropped on the upper surface of the anti-skid grating plate 2 from accumulating on its upper surface, thereby effectively preventing the transport vehicle from slipping on the upper surface of the anti-skid grating plate 2.

[0032] Furthermore, at least one set of hydraulic telescopic rods 15 is installed on the lower surface of the slope 1, and a universal wheel 16 is installed at the telescopic end of the hydraulic telescopic rod 15.

[0033] Specifically, the axle of the universal wheel 16 is installed on the axle bracket, and the axle bracket is fixed to the telescopic end of the hydraulic telescopic rod 15. The hydraulic telescopic rod 15 can lift the slope 1 by extending, which facilitates the overall movement of the stacker.

[0034] Furthermore, guard plates are provided on both the front and rear sides of the base 3 .

[0035] Specifically, the provision of the guard plate can effectively prevent the material on the upper surface of the grille mesh plate 5 from sliding onto the ground.

[0036] Furthermore, both left and right side surfaces of the longitudinal conveyor 31 are connected to the lower surface of the grid mesh plate 5 through the partition plate 32 .

[0037] Specifically, the partition 32 is installed on the frame of the longitudinal conveyor 31. The longitudinal conveyor 31 is a belt conveyor. Adjacent longitudinal conveyors 31 share a partition 32. Through the diversion of the partition 32, the materials discharged from the grid mesh plate 5 can all fall into the upper surface of the longitudinal conveyor 31, and due to the obstruction of the partition 32, the materials on the upper surface of the longitudinal conveyor 31 will not be thrown to the left and right sides when the longitudinal conveyor 31 is working.

[0038] Furthermore, the longitudinal walking mechanism includes a hydraulic telescopic rod 25 and a positioning sleeve 26 installed on the outer side of the base 3, the inner side of the positioning sleeve 26 is sleeved with a lifting rod 27, the telescopic end of the hydraulic telescopic rod 25 is installed with a lifting frame 24, the lifting frame 24 is rotatably connected to the Y-axis 22 through a bearing support, the outer side of the Y-axis 22 is installed with a walking roller 23, the upper surface of the lifting frame 24 is connected to the lower end surface of the lifting rod 27, the Y-axis 22 is installed with a sprocket 21, the upper surface of the lifting frame 24 is installed with a support rod 19, the upper end surface of the support rod 19 is installed with a Y-axis walking motor 17, the output shaft of the Y-axis walking motor 17 is installed with a sprocket 18, and the sprocket 18 is connected to the sprocket 21 through a chain 20.

[0039] Specifically, the hydraulic telescopic rod 25 can drive the walking roller 1 23 to rise and fall by telescoping. When the walking roller 1 23 touches the ground, the base 3 can be lifted, and then the sprocket 18 is driven to rotate by the Y-axis walking motor 17. The sprocket 18 drives the sprocket 2 21 to rotate through the chain 20, and the sprocket 2 21 drives the walking roller 1 23 to rotate, thereby realizing the longitudinal movement of the base 3.

[0040] Furthermore, the supporting device includes an equipment bracket 11 installed on the outer side of the base 3, at least one positioning rod 9 is installed on the upper surface of the equipment bracket 11, the outer side of the positioning rod 9 is slidably connected to a motor mounting seat 10, a stepper motor 8 is installed on the motor mounting seat 10, the output shaft of the stepper motor 8 is connected to a positioning screw 14, a positioning nut 13 is installed on the upper surface of the equipment bracket 11, the positioning screw 14 is threadedly connected to the positioning nut 13, and a support leg 12 is installed on the lower end surface of the positioning screw 14.

[0041] Specifically, the output shaft of the stepper motor 8 drives the positioning screw 14 to rotate, and the lifting and lowering of the support leg 12 can be adjusted to meet different usage scenarios.

[0042] More specifically, when the ground is uneven, the support legs 12 can be adjusted to different heights to level the base 3, thereby facilitating unloading.

[0043] Furthermore, the conveyor support 71 is fixed to the outer side of the base 3 through a connecting rod 76, and at least one hydraulic telescopic rod three 75 is installed on the outer side of the conveyor support 71, and a universal wheel two 74 is installed at the telescopic end of the hydraulic telescopic rod three 75.

[0044] Specifically, the hydraulic telescopic rod 3 75 can place the universal wheel 2 74 on the ground by telescoping, so that the stacking conveyor 7 can move together with the base 3 .

[0045] Furthermore, the stacking conveyor 7 includes a conveyor bracket 71, and a high-angle belt conveyor 73 is installed on the upper surface of the conveyor bracket 71. The high-angle belt conveyor 73 consists of a horizontal section and an inclined section, wherein the horizontal section is arranged at the unloading end of the longitudinal conveyor 31 to receive the material unloaded by the longitudinal conveyor 31.

[0046] Specifically, the materials conveyed by the longitudinal conveyor 31 fall on the upper surface of the steep-angle belt conveyor 73, and then the steep-angle belt conveyor 73 is started, and the steep-angle belt conveyor 73 transports the materials to a high place and throws them down, so that the materials can be piled together.

[0047] Furthermore, the horizontal section of the steep-angle belt conveyor 73 is covered with a protective cover 72 , and the discharge end of the steep-angle belt conveyor 73 is installed with a guide cover.

[0048] Specifically, the guide hood is a conical hood that is wide at the top and narrow at the bottom, and is used to gather the materials when unloading.

[0049] When in use: First, make sure the mobile bulk material stacker is in good working condition, check whether all hydraulic systems, motors, conveyors and walking mechanisms are operating normally, adjust the supporting device as needed, and ensure that the base 3 is level and stable.

[0050] Move the mobile bulk material stacker to a suitable position so that the parking platform 6 is aligned with the unloading area of ​​the transport vehicle. If the ground is uneven, the height of the supporting legs 12 can be adjusted to achieve the levelness of the base 3 .

[0051] The transport vehicle is started and slowly reversed toward the parking platform 6 until the rear wheels touch the blocking rod 4. The transport vehicle completes the self-unloading of the materials. At this time, the materials will directly fall on the grid mesh plate 5 and fall through the mesh holes onto the longitudinal conveyor 31 below.

[0052] The longitudinal conveyor 31 is started to convey the material from the grid mesh plate 5 to the stacking conveyor 7. The material is smoothly conveyed on the longitudinal conveyor 31 and is finally transferred to the stacking position.

[0053] When the material is stacked, turn off all conveyors and motors, retract the hydraulic telescopic rod, lower the universal wheels, and return the equipment to its original position. If necessary, the equipment can be moved to the next working position or stored.

[0054] After each use, clean the residual materials on the equipment, check and maintain each component to ensure that the equipment can work normally the next time it is used.

[0055] It is worth noting that the extension and retraction of the hydraulic telescopic rod three 75, the hydraulic telescopic rod one 15 and the hydraulic telescopic rod two 25 are all controlled by an external hydraulic station, and the input ends of the stacking conveyor 7, the stepper motor 8, the Y-axis travel motor 17 and the X-axis travel motor 28 are all electrically connected to the output end of the external power supply through an external control switch.

[0056] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
