Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker-reclaimer technology, and in particular to a fully automatic stacker-reclaimer with constant flow regulation function. Background Technology
[0002] According to a stacker-reclaimer disclosed in Chinese Patent No. CN220033325U, the stacker-reclaimer includes a stacker body for stacking materials. One side of the stacker body has a three-dimensional imaging structure for forming a three-dimensional image of the stacking space. The three-dimensional imaging structure has a dust-blowing structure for removing dust from its components. The three-dimensional imaging structure includes a mounting column located on one side of the stacker body, and the mounting column is movably connected to a mounting frame via a hinge. A through slot is provided on one side of the mounting frame to facilitate the installation of the dust-blowing structure components. The lower part of the mounting frame is also movably connected to an adjusting cylinder via a hinge. A three-dimensional imager is located inside the mounting frame via a connecting column. The dust-blowing structure includes a connecting pipe with a blowpipe embedded on one side, and the connecting pipe is located inside the mounting frame via a telescopic cylinder. This stacker-reclaimer, through the mounting column, achieves both installation and load-bearing support.
[0003] The aforementioned documents and existing technologies have the following problems: The position of the conveyor belt in the current fully automatic stacker-reclaimer is usually fixed. Due to the difference in the speed of the conveyor belt transporting coal blocks, it is difficult to control the landing point accurately. This causes the coal blocks to scatter or accumulate in improper positions due to the landing point deviation. It cannot be ensured that the coal blocks can fall stably into the target coal pile, which is not convenient to maintain the flow stability of coal blocks throughout the stacker-reclaimer process and reduces the continuity and stability of the coal block transportation process. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic stacker-reclaimer with constant flow regulation function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic stacker-reclaimer with constant flow regulation function, comprising a base and a grab bucket, wherein a hydraulic rod is provided on the surface of the base, a track is provided at the top of the hydraulic rod, a movable groove is provided on the side of the track, a moving component is provided inside the movable groove, a mounting frame is provided on the surface of the moving component, a conveyor belt is provided on the surface of the mounting frame, a laser rangefinder is provided on the side of the mounting frame, a bracket is provided on the surface of the track, and a camera is provided at the top of the bracket.
[0006] Preferably, the moving component includes a servo motor, a lead screw, a moving seat, a connecting seat, and a guide rod. The output end of the servo motor is provided with a lead screw, the surface of the lead screw is provided with a moving seat, the side of the moving seat is provided with a connecting seat, and the surface of the moving seat away from the servo motor is connected through a guide rod.
[0007] Preferably, the base has a controller on its surface, and the grab bucket is located on one side of the base.
[0008] Preferably, the surface of the track is provided with a groove, and the side of the mounting bracket is provided with a slider.
[0009] Preferably, the shape and position of the slider are adapted to the slide groove, and the mounting bracket is slidably connected to the track through the slider and the slide groove.
[0010] Preferably, the bottom surface of the mounting bracket is fixedly connected to the surface of the connecting seat, and the two movable seats are connected through the connecting seat.
[0011] Preferably, the camera and the laser rangefinder are electrically connected to the controller, and the moving component is electrically connected to the controller.
[0012] Beneficial effects
[0013] This invention employs a moving component, a laser rangefinder, and a camera. The laser rangefinder accurately measures the distance between the conveyor belt and the coal pile in real time, while the camera clearly captures the landing point of coal blocks on the coal pile. Both feed the data back to the controller. Based on this data and the conveyor belt's speed, the controller drives the moving component to precisely adjust the conveyor belt's position, ensuring that coal blocks fall stably and accurately into the target coal pile regardless of the conveying speed. This avoids coal scattering and improper accumulation. Whether rapidly retrieving large quantities of coal or precisely stacking them in a space-constrained area, the controller can flexibly adjust the horizontal distance between the conveyor belt and the coal pile according to the coal block conveying speed and the actual conditions of the coal pile, ensuring that the coal blocks fall accurately into the target position. This constant flow regulation effectively maintains a stable flow rate of coal blocks throughout the entire material handling process, greatly improving the continuity and stability of the coal conveying process.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0023] Reference Figure 1-4 A fully automatic stacker-reclaimer with constant flow regulation function includes a base 1 and a grab bucket 2. The grab bucket 2 is responsible for grabbing coal blocks, extracting them from the coal pile, and placing them onto a conveyor belt 7. It is the key component for transferring coal blocks from their original stacking position to the conveyor belt 7. A controller 3 is installed on the surface of the base 1. A camera 10 and a laser rangefinder 8 are electrically connected to the controller 3. A moving component 13 is also electrically connected to the controller 3. The controller 3, as the core control unit of the entire system, receives data from the laser rangefinder 8 and the camera 10. Combined with preset parameters such as the conveyor belt 7's conveying speed, it uses a specific algorithm to calculate the optimal horizontal distance between the conveyor belt 7 and the coal pile. Based on the calculation results, the controller 3 sends instructions to the moving component 13 to drive it to adjust the position of the conveyor belt 7, thereby achieving precise coal block placement. The grab bucket 2 is located on one side of the base 1, which has point control and constant flow regulation functions. The base 1 has a hydraulic rod 4 on its surface. The main function of the hydraulic rod 4 is to adjust the height of the track 5 and the conveyor belt 7 installed on the track 5. By adjusting the height, the parabolic trajectory of the coal block falling from the conveyor belt 7 can be further optimized. In conjunction with the moving component 13, it can ensure that the coal block can accurately fall into the target coal pile under different working conditions, thereby improving the accuracy and stability of coal block transportation. The top of the hydraulic rod 4 is provided with the track 5, which provides guidance for the movement of the moving component 13 and the conveyor belt 7, ensuring that the movement of the conveyor belt 7 in the horizontal direction has good straightness and stability. The side of the track 5 is provided with a movable groove 12, which provides installation and movement space for the moving component 13 and prevents it from deviating or shaking during movement.
[0024] The movable slot 12 is equipped with a moving component 13, which includes a servo motor 1301, a lead screw 1302, a moving seat 1303, a connecting seat 1304, and a guide rod 1305. The output end of the servo motor 1301 is provided with the lead screw 1302, the surface of the lead screw 1302 is provided with the moving seat 1303, and the side of the moving seat 1303 is provided with the connecting seat 1304. The surface of the moving seat 1303 away from the servo motor 1301 is connected to the guide rod 1305. The servo motor 1301 serves as the power source for the moving component 13 and receives commands from the controller 3. The lead screw 1302 rotates under the drive of the servo motor 1301, converting the rotational motion of the servo motor 1301 into the linear motion of the moving seat 1303, thereby driving the connecting seat 1304 to move, thus driving the mounting frame 6 and the conveyor belt 7 to move. The guide rod 1305 is mainly used to guide the movement of the moving seat 1303, preventing the moving seat 1303 from rotating or deviating under the drive of the lead screw 1302, and ensuring that the moving seat 1303 can move smoothly along the predetermined straight direction. The bottom surface of the mounting frame 6 is fixedly connected to the surface of the connecting seat 1304. The two moving seats 1303 are connected through the connecting seat 1304. The surface of the moving component 13 is provided with the mounting frame 6, and the surface of the mounting frame 6 is provided with the conveyor belt 7. The conveyor belt 7 is responsible for transporting the coal blocks grabbed by the grab bucket 2 to the designated position. Driven by the moving component 13, the position can be flexibly adjusted in the horizontal direction to adapt to the parabolic trajectory changes under different coal block conveying speeds, ensuring that the coal blocks can accurately fall into the target coal pile range, and realizing the stable conveying and constant flow regulation function of the coal blocks.
[0025] The surface of track 5 is provided with a groove 11, and the side of the mounting frame 6 is provided with a slider 14. The shape and position of the slider 14 are adapted to the groove 11. The mounting frame 6 is slidably connected to track 5 through the slider 14 and the groove 11. The groove 11 is adapted to the slider 14 on the side of the mounting frame 6, providing guidance and support for the movement of the mounting frame 6 and the conveyor belt 7, so that the mounting frame 6 can slide smoothly along track 5, ensuring the stability of the conveyor belt 7 during horizontal movement. The side of the mounting frame 6 is provided with a laser rangefinder 8, which measures the horizontal distance between the discharge point of the conveyor belt 7 and the edge of the coal pile in real time, and feeds the measurement data back to the controller 3 in real time, so that the controller 3 can calculate the optimal horizontal distance between the conveyor belt 7 and the coal pile based on these data, thereby driving the conveyor belt 7. The moving component 13 adjusts the position of the conveyor belt 7 to achieve precise control of the coal block's landing point. The surface of the track 5 is equipped with a bracket 9, which fixes the camera 10 at a suitable height and angle, enabling it to clearly capture the entire coal pile and the distribution of coal blocks' landing points on the coal pile. The top of the bracket 9 is equipped with a camera 10, which uses visual recognition technology to identify the distribution of coal blocks' landing points on the coal pile and transmits the image data to the controller 3. Combined with the data from the laser rangefinder 8, the controller 3 receives comprehensive information, enabling it to more accurately determine whether the current position of the conveyor belt 7 is appropriate and make more precise adjustment decisions to ensure that the coal blocks accurately fall into the target coal pile range, thus achieving constant flow regulation.
[0026] When operating this fully automatic stacker-reclaimer with constant flow regulation, the grab bucket 2 is first started. It grabs coal blocks from the coal pile and places them onto the conveyor belt 7. At this time, the laser rangefinder 8 measures the horizontal distance between the discharge point of the conveyor belt 7 and the edge of the coal pile in real time, while the camera 10 uses visual recognition technology to clearly capture the distribution of coal blocks landing on the coal pile. Both feed the data back to the controller 3. The controller 3, as the core control unit, calculates the optimal horizontal distance between the conveyor belt 7 and the coal pile using a specific algorithm, combined with preset parameters such as the conveyor belt 7's conveying speed. Then, it sends a command to the moving component 13. The servo motor 1301 of the moving component 13 receives the command and drives the lead screw 1302. The rotation converts the rotational motion into linear motion of the moving seat 1303, which in turn drives the connecting seat 1304 and the mounting frame 6 to move, so that the conveyor belt 7 can be precisely adjusted in the horizontal direction. At the same time, the hydraulic rod 4 can adjust the height of the conveyor belt 7 as needed to optimize the parabolic trajectory of the coal blocks falling from the conveyor belt 7. Throughout the process, the chute 11 and the slider 14 cooperate to provide guidance and support for the movement of the mounting frame 6 and the conveyor belt 7, ensuring the stability of their horizontal movement. Ultimately, no matter how the coal block conveying speed changes, it can ensure that the coal blocks fall stably and accurately into the target coal pile range, achieving constant flow regulation and maintaining the stability of the flow rate and the continuity and stability of the conveying of coal blocks during the stacking and reclaiming process. Specific Implementation Example 2:
[0028] A fully automatic stacker-reclaimer with constant flow regulation function, based on the basic structure in Specific Embodiment 1, further discloses the following: In some scenarios with extremely high precision requirements and complex environments, the laser rangefinder 8 can be replaced with a lidar sensor. Lidar has higher resolution and measurement accuracy, and can obtain more detailed coal pile shape information, helping the system to plan a more accurate conveyor belt 7 movement path and stacking area. The specific usage can be selected and adjusted according to actual needs.
[0029] In summary:
[0030] 1. The system employs a moving component 13, a laser rangefinder 8, and a camera 10. The laser rangefinder 8 can accurately measure the distance between the conveyor belt 7 and the coal pile in real time, while the camera 10 can clearly capture the landing point of the coal blocks on the coal pile. Both feed the data back to the controller 3. Based on this data and the conveying speed of the conveyor belt 7, the controller 3 can drive the moving component 13 to precisely adjust the position of the conveyor belt 7, ensuring that the coal blocks can fall stably and accurately into the target coal pile area regardless of the conveying speed. This avoids the scattering and improper accumulation of coal blocks. Whether it is rapidly stacking a large number of coal blocks or accurately stacking them in a space-constrained area, the controller 3 can flexibly adjust the horizontal distance between the conveyor belt 7 and the coal pile according to the coal block conveying speed and the actual situation of the coal pile, ensuring that the coal blocks fall accurately into the target position. This achieves constant flow regulation, effectively maintaining the stable flow of coal blocks throughout the entire stacking and reclaiming process, and greatly improving the continuity and stability of the coal block conveying process.
