Description

Technical Field

[0001] This application relates to the technical field of material storage, and in particular to a stone storage device. Background Technology

[0002] In construction, road building, and mining, stone is a crucial raw material, and its storage and transportation directly impact construction efficiency and cost control. Currently, some traditional stone storage facilities use only simple silos. When the stone is needed, it often requires large hoisting equipment or manual labor for handling, which is not only labor-intensive but also inefficient, failing to meet the demands of continuous large-scale construction projects. Furthermore, manual handling easily leads to stone spillage, wasting raw materials and increasing project costs. To address the low transfer efficiency of traditional equipment, some stone storage devices are equipped with conveying and transfer components on their hoppers. However, due to differences in stone particle size, moisture content, and other characteristics, the required discharge speed varies across different construction scenarios. Most existing storage devices cannot flexibly adjust the discharge speed according to actual needs. If the discharge speed is too fast, excessive stone accumulation in the transport vehicle can easily exceed its load capacity; conversely, if the discharge speed is too slow, it will affect the progress of subsequent construction processes and reduce overall construction efficiency. Utility Model Content In order to improve the problem that the storage device cannot flexibly adjust the discharge speed according to actual needs, which may easily exceed the load capacity of the transport vehicle or reduce the overall construction efficiency, this application provides a stone storage device.

[0003] This application provides a stone storage device, which adopts the following technical solution: A stone storage device includes a base plate, a hoist for conveying stones, a storage bin, and a transport component. The hoist, the storage bin, and the transport component are all mounted on the base plate. The discharge end of the hoist is connected to the inlet end of the storage bin. A temporary storage tank is provided at the discharge end of the storage bin. An adjustment unit is provided on the top of the temporary storage tank to control the discharge speed of the stones in the storage bin. Multiple telescopic cylinders are provided outside the temporary storage tank. The ends of the multiple telescopic cylinders are connected to a cover. The transport component is located below the cover. The transport assembly includes a transport vehicle for transferring the stones and a weighing ramp. A weighbridge is installed in the weighing ramp, and the transport vehicle moves on the weighing ramp to transfer the stones falling from the cover into the transport vehicle.

[0004] By adopting the above technical solutions, the base plate provides a unified installation foundation for the elevator, storage silo, and transportation components, ensuring the stability of the entire device structure. The elevator enables automated transport of stones from a lower level to the storage silo, replacing traditional manual or hoisting equipment handling, significantly reducing labor intensity and improving transport efficiency. The storage silo provides centralized storage space for stones, meeting the stone storage needs of large-scale projects. The temporary storage bucket, in conjunction with the adjustment unit, can flexibly control the stone discharge speed according to construction needs, avoiding excessively fast discharge that could overload the transport vehicle or excessively slow discharge that could affect the construction progress. The multi-layer telescopic cylinder, in conjunction with the cover, can accurately guide the stones to fall into the transport vehicle below, reducing spillage and waste during stone transfer. In the transportation components, the weighbridge in the weighing lane can simultaneously weigh the stones during the transfer process, eliminating the need for additional transport to the weighing location, shortening the construction process. The transport vehicle enables convenient transfer of stones from the storage area to the construction area, improving project construction efficiency. Optionally, the adjustment unit includes a telescopic cylinder, a connecting rod, a rotating shaft, and an adjustment plate installed outside the temporary storage tank. The output end of the telescopic cylinder is rotatably connected to the connecting rod, and the other end of the connecting rod is rotatably connected to the rotating shaft. The rotating shaft is rotatably mounted on the temporary storage tank, and one end of the adjustment plate is sleeved on the rotating shaft. The telescopic cylinder drives the adjustment plate to rotate through the connecting rod to open, adjust, or close the discharge port of the temporary storage tank. By adopting the above technical solution, the telescopic cylinder serves as the power source. Its telescopic movement is transmitted to the rotating shaft via a connecting rod, causing the rotating shaft to rotate, which in turn causes the adjusting plate sleeved on the rotating shaft to rotate synchronously. When the adjusting plate rotates, the opening and closing of the temporary storage bin's discharge port, as well as the adjustment of the opening degree, can be realized: opening it meets the needs of stone falling, closing it can pause the discharge, and adjusting the opening degree can control the flow rate of stone through the discharge port, thereby achieving flexible control of the discharge speed of the storage bin. It can quickly respond according to the characteristics of stone particles, moisture content, and other factors, as well as the needs of the construction scenario, ensuring that the discharge speed always matches the actual construction speed, thus improving the adaptability and ease of operation of the device. Optionally, a support frame is mounted on the base plate, the storage bin is mounted on the support frame, the transport component is located below the support frame, and a through hole is provided on the top of the support frame for multiple telescopic cylinders to pass through. By adopting the above technical solution, the support frame elevates the storage bin, creating a layered layout with the transport components below, effectively utilizing vertical space. Through holes provide passageways for the multi-layered telescopic cylinders, ensuring accurate connection between the cylinders and the lower cover, stabilizing the stone's descent path and preventing stone spillage due to cylinder misalignment. Optionally, a dust collector is provided on the top of the support frame, and the dust collection port of the dust collector is located above the transport assembly. By adopting the above technical solution, dust is easily generated during the process of stone falling from the cover to the transport vehicle. The dust collector can suck up and treat the dust generated during the stone transfer process in a timely manner through the dust suction port located above the transport component, effectively reducing the dust concentration at the construction site. Optionally, the multi-layer telescopic cylinder includes a first cylinder, a plurality of second cylinders and a third cylinder that are slidably sleeved on each other in sequence. The first cylinder is connected to the temporary storage bucket. Among the plurality of second cylinders, the innermost second cylinder is slidably sleeved on the outside of the first cylinder, and the third cylinder is slidably sleeved on the outermost second cylinder. A support plate is installed at the bottom of the storage bin. Rotating rollers are symmetrically installed on the support plate near the support frame. A driving component is installed on one side of the rotating rollers. A steel wire rope is sleeved on the rotating rollers, and the other end of the steel wire rope is connected to the third cylinder. By adopting the above technical solution, the multi-layer telescopic cylinder adopts a structure in which the first cylinder, multiple second cylinders, and the third cylinder are slidably nested together in sequence, which can realize the extension and retraction adjustment in the length direction. When the driving component drives the rotating roller to rotate, the rotating roller retracts the steel wire rope, and the steel wire rope pulls the third cylinder, thereby driving multiple second cylinders to slide along the first cylinder, realizing the overall extension or shortening of the telescopic cylinder. The distance between the cover and the transport vehicle can be flexibly adjusted according to the height of the transport vehicle. When the transport vehicle approaches, the telescopic cylinder extends so that the cover is close to the feed inlet of the transport vehicle, reducing the dust diffusion and spillage during the falling of the stone; when the transport vehicle leaves, the telescopic cylinder shortens to avoid occupying too much space. Optionally, a flexible dustproof curtain is provided at the bottom edge of the cover. By adopting the above technical solution, the flexible dust curtain has excellent flexibility. When the cover is close to the transport vehicle, the dust curtain can fit the top edge of the transport vehicle to form a closed unloading space, further preventing the escape of dust during the falling of stones. Combined with the dust collector, it forms a dual dustproof effect, significantly improving dustproof efficiency. At the same time, the flexible material avoids rigid collisions between the cover and the transport vehicle, protecting both from damage, and does not affect the normal movement and positioning of the transport vehicle. Optionally, gratings and cameras are installed on both sides of the weighing track, and a pole is installed along the transport direction of the weighing track and on one side of the end of the support frame. A display screen and an alarm are installed on the pole. By adopting the above technical solutions, the grating can detect the position of the transport vehicle on the weighing track in real time. When the transport vehicle is not accurately positioned under the cover, the grating sends a signal to prevent the adjustment unit from opening and causing the stone to spill. The camera can record the stone transfer process in real time. The display screen on the pole can display key parameters such as the weighbridge weighing data and the transport vehicle's position information in real time, allowing operators to monitor the construction status. When abnormal weighing data or transport vehicle position deviations occur, the alarm will sound in time to remind the operator to make adjustments, avoiding safety accidents or construction errors, and improving the intelligence and safety assurance capabilities of the device. Optionally, a guide plate is provided at the top of the storage silo, and the guide plate is located on the feed end side of the storage silo. By adopting the above technical solution, the guide plate can guide the falling stones, so that the stones are evenly distributed in the storage bin. The guide plate can also buffer the impact force of the falling stones, reduce the impact and wear of the stones on the bottom of the storage bin, and extend the service life of the storage bin. Optionally, a first staircase connects the top of the elevator to the top of the storage silo, and a second staircase is provided outside the storage silo, the second staircase being spirally arranged. By adopting the above technical solution, the first staircase facilitates operators' access to the top of the hoist or storage silo for equipment inspection, maintenance, or cleaning. The spiral second staircase outside the storage silo provides operators with a comprehensive maintenance access route. Compared to the straight staircase of the first staircase, it has a gentler slope, making climbing easier and safer, and the spiral structure saves space.

[0005] In summary, this application includes at least one of the following beneficial technical effects: 1. This device transports stones from the elevator to the storage bin, adjusts the discharge speed to the adjustment unit, and then weighs and transfers the materials synchronously using the transport components. It replaces traditional manual operation, significantly reduces labor intensity, shortens the construction process, improves construction efficiency, and at the same time reduces stone spillage and waste, thus lowering project costs. 2. The dual dust protection of dust collector and flexible dust curtain effectively improves the construction environment. The combination of light grating, alarm and display screen can monitor the equipment status and construction parameters in real time, give early warning of abnormal situations, avoid safety accidents and construction errors, and improve the environmental protection and safety of the device.

[0011] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0012] This application discloses a stone storage device, referring to... Figures 1-3 The stone storage device includes a base plate 1, an elevator 2 for conveying stone, a storage bin 4, and a transport component 8. The elevator 2, the storage bin 4, and the transport component 8 are all mounted on the base plate 1. The discharge end of the elevator 2 is connected to the inlet end of the storage bin 4. A temporary storage bin 5 is provided at the discharge end of the storage bin 4. An adjustment unit 6 is provided on the top of the temporary storage bin 5 to control the discharge speed of the stone in the storage bin 4. The temporary storage bin 5 is covered with multiple telescopic cylinders 7. The ends of the multiple telescopic cylinders 7 are connected to a cover 74. The transport component 8 is located below the cover 74. The transport component 8 includes a transport vehicle 81 for transferring stones and a weighing channel 82. A weighbridge is installed in the weighing channel 82, and the transport vehicle 81 moves on the weighing channel 82 to transfer the stones falling from the cover 74 into the transport vehicle 81.

[0013] In this device, base plate 1 provides a unified and stable installation platform for elevator 2, storage silo 4, and transport components 8, and also isolates the equipment from ground moisture and debris. The feed end of elevator 2 can connect to the stone stacking area, and the discharge end is connected to the feed end of storage silo 4, enabling vertical or inclined transport of stones from lower locations to storage silo 4. This replaces traditional manual handling or large hoisting equipment transport methods, significantly reducing the labor intensity of operators and meeting the stone supply needs of large-scale continuous construction projects. Storage bin 4 provides temporary or long-term storage space for stones, reducing contact between stones and the external environment, lowering the risk of impurities entering, and ensuring stable stone quality. Its capacity can be set according to project needs to ensure sufficient stone reserves during construction to balance the conveying speed of elevator 2 and the construction material usage speed. Temporary storage bin 5 can temporarily buffer stones falling from storage bin 4, preventing stones from directly impacting telescopic cylinder 7 or transport vehicle 81 and causing flow fluctuations. At the same time, temporary storage bin 5 provides an installation carrier for adjustment unit 6, which works with adjustment unit 6 to control stone flow and ensure uniform discharge speed, solving the problem of inconsistent discharge speed in traditional devices. The adjustment unit 6 can adjust the opening of the discharge port of the temporary storage bucket 5 according to the size and moisture of the stone particles and the needs of the construction scene, thereby regulating the stone flow rate and avoiding the risk of overloading of the transport vehicle 81 due to excessive stone accumulation, reducing equipment failures or safety accidents caused by overloading; at the same time, it ensures that the discharge speed matches the construction progress, avoids the downtime of subsequent processes due to lack of materials, improves the overall construction efficiency, and ensures that stones with different characteristics can be discharged stably. The multi-layer telescopic cylinder 7 is telescopically adjusted according to the height of the transport vehicle 81, changing the distance between the cover 74 and the inlet of the transport vehicle 81, ensuring that the stone can fall accurately into the transport vehicle 81, reducing raw material waste, and forming a closed discharge channel to reduce the diffusion and spillage of dust during the stone's fall. The cover 74 forms a closed space for the stone to fall, further guiding the stone to fall accurately into the transport vehicle 81, while preventing the dust generated during the stone's fall from spreading in all directions. In the transport component 8, the transport vehicle 81 serves as the carrier for transferring stones. It moves along the weighing ramp 82, receiving stones falling from the cover 74 and transferring them from the storage area to the construction area or other processing stages, replacing traditional manual cart transport and improving efficiency. The weighing ramp 82 provides a track for the transport vehicle 81, limiting its movement path and ensuring it stops precisely under the cover 74. Simultaneously, the weighing ramp 82 provides an installation foundation for the weighbridge, integrating it into the weighing ramp 82 to achieve integrated transport and weighing. The weighbridge simultaneously weighs the stones as the transport vehicle 81 receives them, acquiring real-time weight data. This, combined with the device's control components, enables quantitative loading, preventing overloading or underloading, ensuring each vehicle's load meets construction requirements, reducing the number of round trips due to insufficient loading, and improving overall transport efficiency. This stone storage device achieves automated stone conveying, centralized storage, precise speed control for discharge, closed-loop transfer, and synchronous weighing. Through the coordinated operation of its components, it forms a coherent and efficient stone processing system, improving both the transfer and construction efficiency of stone, and meeting the large-scale and precise needs of construction, road construction, and other fields for stone storage and transfer. Specifically, the temporary storage tank 5, used in conjunction with the adjustment unit 6, can flexibly control the stone discharge speed according to construction needs, preventing excessively fast discharge from overloading the transport vehicle 81 or excessively slow discharge from affecting the construction progress.

[0014] Reference Figure 2 A guide plate 41 is installed at the top of the storage silo 4, located on the feed end side of the storage silo 4. The guide plate 41 guides and diverts the stones conveyed to the storage silo 4 by the elevator 2. When the elevator 2 feeds the stones into the storage silo 4 from the feed end, the stones will concentrate and impact the area near the feed end due to inertia. The guide plate 41 changes the falling trajectory of the stones by its own tilt angle, guiding the concentrated stones to other spaces inside the storage silo 4, making full use of the storage capacity of the storage silo 4. At the same time, the guide plate 41 can buffer the impact force when the stones fall, reduce the force of the stones directly hitting the inner wall or bottom of the storage silo 4, and extend the service life of the storage silo 4.

[0015] Reference Figure 3 and Figure 4The adjustment unit 6 includes a telescopic cylinder 61, a connecting rod 62, a rotating shaft 63, and an adjustment plate 64 installed outside the temporary storage tank 5. The output end of the telescopic cylinder 61 is rotatably connected to the connecting rod 62, and the other end of the connecting rod 62 is rotatably connected to the rotating shaft 63. The rotating shaft 63 is rotatably mounted on the temporary storage tank 5. One end of the adjustment plate 64 is sleeved on the rotating shaft 63. The telescopic cylinder 61 drives the adjustment plate 64 to rotate via the connecting rod 62 to open, adjust, or close the discharge port of the temporary storage tank 5. The telescopic cylinder 61 provides power output to the entire adjustment unit 6 through the extension and retraction of its piston rod. It can extend, retract, or stop at a specific position according to control commands, thereby driving the movement of subsequent components to meet the adjustment requirements of the discharge speed under different working conditions. Connecting rod 62 converts the linear motion of the piston rod of telescopic cylinder 61 into the rotational motion of rotating shaft 63. When telescopic cylinder 61 actuates, connecting rod 62 can swing flexibly, ensuring smooth power transmission without jamming and achieving a seamless transition between motion modes. One end of rotating shaft 63 is connected to connecting rod 62 to receive power, while the other end is fitted with adjusting plate 64, which transmits the rotational motion from connecting rod 62 to adjusting plate 64, allowing adjusting plate 64 to precisely change its angle with the rotation of rotating shaft 63. Stable rotation of rotating shaft 63 prevents adjusting plate 64 from shifting or wobbling during operation, ensuring precise blocking or opening of the discharge port of temporary storage tank 5 by adjusting plate 64, thereby ensuring accurate control of the discharge speed. The adjusting plate 64 rotates with the rotating shaft 63, changing its relative position to the discharge port of the temporary storage tank 5, thus enabling the discharge port to be opened, closed, or its opening degree adjusted. When the adjusting plate 64 rotates to completely block the discharge port, the discharge is closed; when it rotates to completely leave the discharge port, the discharge is at its maximum opening degree; when it rotates to partially block the discharge port, the effective flow area of ​​the discharge port is adjusted by changing the blocking area, thereby controlling the discharge speed. This allows for flexible control of the discharge speed according to construction needs, solving the problem that traditional devices cannot adapt to different stone characteristics (such as particle size and moisture content) and construction rhythms, ensuring a uniform and stable discharge speed, avoiding overload or low efficiency problems caused by the fixed discharge speed of traditional devices, and meeting the discharge requirements under different working conditions. Reference Figures 1-3 A support frame 3 is mounted on the base plate 1, and the storage bin 4 is mounted on the support frame 3. The transport component 8 is located below the support frame 3. The top of the support frame 3 has a through hole for the multi-layer telescopic cylinder 7 to pass through. The support frame 3 raises the storage bin 4 to a certain height, so that there is enough space below the storage bin 4 to accommodate the transport component 8 and the transport vehicle 81 to move forward. This realizes the upper and lower layered layout of the storage bin 4 and the transport component 8, effectively utilizing vertical space. At the same time, the support frame 3, through its own rigid structure, bears the weight of the storage bin 4 and the stones inside, maintaining the stable posture of the storage bin 4 and preventing the storage bin 4 from deforming or tilting due to excessive weight or external forces. The through-hole provides a passage for the multi-layer telescopic cylinder 7, allowing it to extend from the temporary storage tank 5 to the top of the lower transport component 8. This ensures that the stones can smoothly fall through the multi-layer telescopic cylinder 7 onto the transport vehicle 81, reducing stone spillage. Simultaneously, the through-hole serves to position and guide the multi-layer telescopic cylinder 7, limiting its lateral displacement. Reference Figure 3 and Figure 4 The multi-layer telescopic cylinder 7 includes a first cylinder 71, a plurality of second cylinders 72 and a third cylinder 73 that are slidably fitted together in sequence. The first cylinder 71 is connected to the temporary storage tank 5. Among the plurality of second cylinders 72, the innermost second cylinder 72 is slidably fitted around the first cylinder 71, and the third cylinder 73 is slidably fitted around the outermost second cylinder 72. A support plate 43 is installed at the bottom of the storage bin 4. Rotating rollers 44 are symmetrically installed on the support plate 43 near the support frame 3. A driving component 442 is installed on one side of the rotating rollers 44. A steel wire rope 441 is fitted on the rotating rollers 44, and the other end of the steel wire rope 441 is connected to the third cylinder 73.

[0016] The first cylinder 71 receives the stones falling from the temporary storage bucket 5, providing an initial conveying channel for the stones and ensuring that the stones can smoothly enter the telescopic cylinder 7 from the temporary storage bucket 5, preventing the stones from spilling at the connection point. The innermost second cylinder 72 is sleeved on the outer side of the other end of the first cylinder 71, providing a fixed reference for the extension and retraction of the subsequent cylinders, limiting the radial offset of the second cylinder 72, and ensuring that the extension and retraction action is carried out in the preset direction.

[0017] Multiple second cylinders 72 are sequentially slidably fitted together. The innermost second cylinder 72 is fitted over the first cylinder 71, and the outermost second cylinders 72 are sequentially fitted over the adjacent innermost second cylinders 72, forming a telescopic intermediate channel structure. By sliding against each other, the total length of the entire telescopic cylinder 7 is changed. Together with the first cylinder 71 and the third cylinder 73, the distance between the cover 74 and the transport vehicle 81 can be adjusted to accommodate transport vehicles 81 of different heights. At the same time, the material guiding function of the first cylinder 71 can be continued to ensure that the stone is always transported within the closed channel during the telescopic process. The third cylinder 73 is the end component of the multi-layer telescopic cylinder 7, integrating the telescopic cylinder 7 and the cover 74 into one unit, and can drive the cover 74 to move up and down synchronously. The other end is connected to the rotating roller 44 via a steel wire rope 441, receiving the power transmitted by the drive component 442, and driving itself and multiple second cylinders 72 to slide along the first cylinder 71, realizing the extension or shortening of the entire telescopic cylinder 7.

[0018] The support plate 43 provides a stable mounting platform for the rotating roller 44, ensuring a reasonable relative position between the rotating roller 44 and the third cylinder 73, allowing the wire rope 441 to maintain a suitable angle connecting the two. Simultaneously, the support plate 43, through its rigid structure, bears the weight of the rotating roller 44 and the drive component 442, preventing installation position deviation due to component weight. The drive component 442 is the power source for the entire telescopic adjustment mechanism. It can output rotational power according to control commands, driving the rotating roller 44 to rotate clockwise or counterclockwise, controlling the winding or unwinding direction of the wire rope 441, and realizing the extension or shortening of the telescopic cylinder 7. This ensures that the cover 74 can be quickly and accurately adjusted to the target height, improving operational convenience and automation.

[0019] The rotating roller 44 receives the rotational power output from the drive unit 442 and rotates itself to wind or release the wire rope 441, providing direct power for the extension and retraction of the telescopic drum 7. The symmetrically arranged rotating rollers 44 ensure balanced force on both sides of the wire rope 441, preventing tilting of the third drum 73 due to unilateral force and ensuring smooth and stable extension and retraction. The wire rope 441 transmits the winding or releasing force generated by the rotation of the rotating roller 44 to the third drum 73, pulling it to slide along the first drum 71. Simultaneously, the two symmetrically arranged wire ropes 441 transmit power synchronously to ensure balanced force on both sides of the third drum 73. Guide sliders are installed between each layer of drums, and a tensioning device is added at the rotating roller 44 to ensure the tension of the wire rope 441, ensuring smooth and synchronous extension and retraction of the multi-layer telescopic drum 7 and improving drive stability.

[0020] A dust collector 31 is installed on the top of the support frame 3. The dust collection port of the dust collector 31 is located above the transport component 8. The support frame 3 provides a stable installation position for the dust collector 31. The dust collector 31 generates negative pressure through an internal fan to form suction, which draws the dust above the transport component 8 into the equipment. The dust is then treated through filtration, separation and other processes, and finally the purified air is discharged, effectively reducing the dust concentration in the air and preventing dust from spreading to the construction area and the surrounding environment. The dust suction port is a channel for dust intake. Its opening faces upwards towards the transport component 8, aiming at the dust source of the falling stone. It can suck up and process the dust before it spreads, greatly reducing the probability of dust spreading to the surrounding environment and further enhancing the dust removal effect. A flexible dustproof curtain 741 is installed at the bottom edge of the cover 74. The dustproof curtain 741 is made of flexible material (such as canvas, plastic, etc.) and can hang down or bend naturally with the rise and fall of the cover 74, fitting the top edge of the transport vehicle 81. It can fill the gap between the cover 74 and the transport vehicle 81, further preventing dust generated when the stones fall from the gap, while avoiding rigid collisions between the cover 74 and the transport vehicle 81. When the transport vehicle 81 moves, the dustproof curtain 741 can deform with the slight shaking of the vehicle without affecting the vehicle's positioning and movement, ensuring smooth transfer operations. Both sides of the weighing ramp 82 are equipped with optical gratings and cameras. A pole is installed along the transport direction of the weighing ramp 82 and on one side of the support frame 3. The pole is equipped with a display screen and an alarm. The optical gratings form an invisible light barrier by emitting and receiving infrared light, allowing real-time monitoring of the position of the transport vehicle 81 on the weighing ramp 82. If the transport vehicle 81 does not stop precisely, the adjustment unit 6 can be prevented from opening the discharge mechanism, preventing stones from spilling onto the weighing ramp 82 or the ground, reducing raw material waste and cleanup work. Simultaneously, it prevents equipment collisions caused by the transport vehicle 81 exceeding the range of the weighing ramp 82, improving safety at the construction site.

[0021] The camera lens is pointed towards the area where the transport vehicle 81 is parked and the stones are falling, and it captures the entire process of stone transfer in real time (such as the amount of stone discharged, the receiving status of the transport vehicle 81, and whether there is any spillage). The recorded images can be used as a basis for tracing the construction process and troubleshooting. At the same time, it can also help operators to remotely observe the on-site situation, avoid operators frequently approaching dusty areas, and reduce the harm of dust to the human body.

[0022] The support pole provides a stable mounting platform for the display screen and alarm, raising both to a height easily observed and noticed by operators, ensuring clear visibility of the display screen information and timely detection of alarm sounds. The display screen shows key construction data and equipment status in real time, such as the weight of stones weighed on the weighbridge, the location information of transport vehicle 81, and the stone discharge speed; it can also play real-time video footage captured by a camera, assisting operators in understanding the site situation. For example, the position of transport vehicle 81 can be moved in real time according to the material discharge situation, improving operational convenience and construction efficiency. When an abnormal situation is detected, such as the grating detecting a positional deviation of the transport vehicle 81, or the weighbridge detecting overload or insufficient weight of the stone, the alarm will sound an alarm through sound or light to remind the operator to deal with it in time and avoid the abnormal situation from escalating into a safety accident or construction error. refer to Figure 1 A first staircase 21 connects the top of the elevator 2 to the top of the storage silo 4, and a second staircase 42 is provided outside the storage silo 4 in a spiral configuration. One end of the elevator 2 is connected to the stone stacking area, and the other end is connected to the feed end of the storage silo 4. Through an internal transmission structure (such as a chain or belt), it transports stones from the lower level to the storage silo 4, providing a continuous supply of stones to the storage silo 4. A maintenance platform or operating area is provided on the top of the elevator 2, which facilitates the inspection, maintenance, and cleaning of the components on the top of the elevator 2 (such as the discharge port and transmission mechanism). The first staircase 21, using a straight or inclined structure, provides maintenance personnel with a convenient passage from the top of the hoist 2 to the top of the storage silo 4, avoiding dangerous methods such as climbing the equipment casing to move between the two. Handrails are usually installed on both sides of the staircase to ensure the safety of personnel going up and down. The second staircase 42 provides maintenance personnel with a direct passage from the bottom of the storage silo 4 to the top of the storage silo 4, facilitating maintenance and repair work. The spiral structure does not require a large additional horizontal space and has a gentle slope, making it more labor-saving and easier to climb than a straight staircase. The implementation process of a stone storage device according to an embodiment of this application is as follows: Start the elevator 2 to transport the stones in the stacking area to the top through the feed end of the elevator 2. The stones enter the storage bin 4 from the discharge end of the elevator 2. The guide plate 41 in the storage bin 4 guides the stones to be evenly distributed in the bin to avoid accumulation at the feed end.

[0023] According to construction requirements, the adjustment unit 6 is activated via the control component. The piston rod of the telescopic cylinder 61 extends / retracts, driving the connecting rod 62 to rotate the rotating shaft 63. The adjustment plate 64 rotates to change the opening of the discharge port of the temporary storage bucket 5. The stone material falls from the storage bin 4 into the temporary storage bucket 5, and after adjustment, it enters the multi-layer telescopic cylinder 7 at a uniform speed, falling along the closed channel towards the cover 74. The dust collector 31 starts simultaneously, and the dust suction port begins to absorb the dust in the channel. The transport vehicle 81 moves slowly on the weighing track 82. After the grating detects that the vehicle has accurately stopped under the cover 74, it sends a signal to the control component to allow material discharge. The adjustment unit 6 keeps the opening of the discharge port stable. The stone falls into the transport vehicle 81 through the cover 74. The weighbridge transmits the weighing data to the display screen in real time.

[0024] When the weight of the stone reaches the construction requirement, the display screen indicates that the weight has met the standard, and the operator controls the adjustment unit 6 to close the discharge port. If the vehicle is misaligned (light grating trigger signal) or other issues occur, the alarm will immediately sound, and the operator will adjust the vehicle position or take other actions. During the transfer process, the camera continuously records the falling status of the stone. If stone spillage is detected, the operation can be paused and the height of the telescopic drum 7 adjusted to ensure that subsequent transfers are normal.

[0025] After the transport vehicle 81 is fully loaded, the control drive unit 442 retracts the wire rope 441, the multi-layer telescopic cylinder 7 retracts to the initial position, the cover 74 separates from the transport vehicle 81, and the transport vehicle 81 drives away from the construction area along the weighing track 82. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
