[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1: As Figure 1-6 As shown, this embodiment provides a conveyor frame structure for loading and unloading construction waste stone, including a conveyor belt 100, support plates 200 at both ends of the conveyor belt 100, multiple support leg assemblies 300 at the lower end of the conveyor belt 100, two hoppers 400 rotatably connected to both ends of the conveyor belt 100, multiple stabilizing blocks 700 between the two support plates 200, and a tensioning assembly 500 inside the conveyor belt 100. The outer peripheral wall of the conveyor belt 100 is fixed with a plurality of fixed blocks 101 arranged in a uniform structure. A baffle block 102 is inserted into the fixed block 101. The baffle block 102 has a hole 103 at both ends. A connecting bolt 104 is inserted into the hole 103 and is threadedly connected to the fixed block 101. The tensioning assembly 500 includes a tensioning roller 501. The outer peripheral wall of the tensioning roller 501 abuts against the inner wall of the conveyor belt 100. Push blocks 502 are respectively sleeved on the outer peripheral walls at both ends of the tensioning roller 501. U-shaped rods 503 are slidably connected to the push blocks 502. A C-shaped block 504 is provided at the upper end of the tensioning roller 501. The two ends of the bottom surface of the C-shaped block 504 are respectively fixedly connected to the upper end of the U-shaped rod 503.
[0026] The conveyor belt 100 has two symmetrical conveyor rollers 105 inside. The outer peripheral wall of the conveyor roller 105 is in frictional contact with the inner wall of the conveyor belt 100. Multiple support rollers 106 are provided between the two conveyor rollers 105. The outer peripheral walls of the multiple support rollers 106 abut against the upper inner wall of the conveyor belt 100. A servo motor 107 is installed on one of the support plates 200. The output shaft of the servo motor 107 is coaxially connected to a reducer. The output shaft of the reducer is coaxially connected to one of the conveyor rollers 105. After the output shaft of the servo motor 107 is reduced by the reducer, it drives one of the coaxially connected conveyor rollers 105 to rotate. The other conveyor roller 105 rotates accordingly, thereby driving the conveyor belt 100 to circulate.
[0027] A limiting groove 505 is provided on the support plate 200, and a spring 506 is fixedly provided on the top surface of the push block 502. The spring 506 is located inside the U-shaped rod 503, and the other ends of the two springs 506 are fixedly connected to the bottom surface of the C-shaped block 504 respectively. The spring 506 plays the role of buffering and auxiliary adjustment, making the tension adjustment more stable, reducing the slippage and deviation problems caused by the slack of the conveyor belt 100, and ensuring the normal and stable operation of the conveyor frame.
[0028] A positioning block 507 is slidably connected to the C-shaped block 504. The bottom surface of the positioning block 507 is fixedly connected to the top surface of the two support plates 200 respectively. A second hydraulic cylinder 508 is installed on the top surface of the C-shaped block 504. The bottom surface of the piston rod of the second hydraulic cylinder 508 is fixedly connected to the top surface of the positioning block 507. The C-shaped block 504 drives the push block 502 to move through the U-shaped rod 503, thereby changing the pressure of the tension roller 501 on the conveyor belt 100 and realizing the adjustment of the tension of the conveyor belt 100.
[0029] One end of the conveyor belt 100 is provided with a blocking block 600. The two ends of the blocking block 600 are fixedly connected to the inner walls of two support plates 200 respectively. One of the hoppers 400 is rotatably connected to the blocking block 600. The middle part of the hopper 400 installed on the blocking block 600 is a telescopic tube. The other hopper 400 is rotatably connected to the two support plates 200 respectively. The hopper 400, which is rotatably connected to the blocking block 600 and has a telescopic tube in the middle, is easy to adjust to different tilt angles, reduces the splashing of waste stone from the lower end of the hopper 400 to the outside, and improves the adaptability of the angle of the hopper 400.
[0030] A first hydraulic cylinder 401 is provided on one side of the hopper 400. A hinge seat 402 is rotatably connected to the piston rod of the first hydraulic cylinder 401. The hinge seat 402 is fixedly connected to the hopper 400. A rotating seat 403 is fixedly provided at the end of the first hydraulic cylinder 401 away from the hinge seat 402. One of the rotating seats 403 is fixedly connected to the blocking block 600, and the other rotating seat 403 is fixedly installed on the bottom surface of one of the stabilizing blocks 700. This allows the hopper 400 to rotate, changing the tilt angle of the hopper 400, which facilitates the loading and unloading of waste stone.
[0031] Working principle: When the conveyor frame for loading and unloading construction waste stone is in operation, the waste stone is poured into the conveyor belt 100 through the hopper 400. The conveyor belt 100 rotates and transports the waste stone to the designated position. During the conveying process, the baffle block 102 is fixed to the fixed block 101 by the connecting bolt 104, which blocks the waste stone and prevents it from overturning and falling or stopping while being transported by the conveyor belt 100. When it is necessary to replace the baffle block 102 with a different style to adapt to different types of waste stone, the connecting bolt 104 can be unscrewed to remove the old baffle block 102. The retaining block 102 is removed from the fixing block 101, and the new retaining block 102 is aligned with the fixing block 101 through the insertion hole 103. The connecting bolt 104 is then tightened to complete the installation. Given the wide variety of construction waste stone materials, as well as the large differences in shape, size, and particle size, the ability to quickly replace different styles of retaining blocks 102 improves the adaptability to different types of waste stone materials, reduces the occurrence of waste stone materials turning over, falling, or stagnating during the conveying process, improves work efficiency, and reduces safety hazards caused by falling waste stone materials. For the tension adjustment of the conveyor belt 100, when it is necessary to adjust the tension of the conveyor belt 100, the piston rod of the second hydraulic cylinder 508 extends and retracts, driving the C-shaped block 504 to move. The C-shaped block 504 drives the push block 502 to move through the U-shaped rod 503, thereby changing the pressure of the tension roller 501 on the conveyor belt 100 and realizing the adjustment of the tension of the conveyor belt 100. During the adjustment process, the spring 506 plays a role in buffering and assisting the adjustment, making the tension adjustment more stable. This reduces problems such as slippage and deviation caused by the slack of the conveyor belt 100, and ensures the normal and stable operation of the conveyor frame. When the conveyor frame for loading and unloading construction waste stone is running, the output shaft of the servo motor 107 is reduced by a reducer and drives one of the coaxially connected conveyor rollers 105 to rotate. As the outer peripheral walls of the two conveyor rollers 105 are in frictional contact with the inner wall of the conveyor belt 100, the other conveyor roller 105 rotates under the drive of the first conveyor roller 105, thereby driving the conveyor belt 100 to circulate. The multiple support rollers 106 located between the two conveyor rollers 105 abut against the upper inner wall of the conveyor belt 100 through their outer peripheral walls, providing support for the conveyor belt 100 and ensuring its smooth transport of waste stone. When the tension of the conveyor belt 100 needs to be adjusted, the piston rod of the second hydraulic cylinder 508 extends and retracts. Since the bottom surface of its piston rod is fixedly connected to the top surface of the positioning block 507, and the C-shaped block 504 is slidably connected to the positioning block 507, the C-shaped block 504 slides along the positioning block 507. When the C-shaped block 504 moves, it drives the push block 502 to slide in the limiting groove 505 through the U-shaped rod 503 connected at both ends. When the push block 502 moves, the push blocks 502 sleeved at both ends of the tension roller 501 will change the pressure of the tension roller 501 on the conveyor belt 100. At the same time, the spring 506 plays a buffering and auxiliary adjustment role in the U-shaped rod 503, realizing the smooth adjustment of the tension of the conveyor belt 100. This reduces the shaking and deviation of the conveyor belt 100 during operation and improves the conveying efficiency. During the loading and unloading of waste rock, the hopper 400 is angled by the first hydraulic cylinder 401. When the piston rod of the first hydraulic cylinder 401 extends or retracts, it drives the hinge seat 402, which is rotatably connected to the piston rod, to move. The hinge seat 402 is fixedly connected to the hopper 400, thereby realizing the rotation of the hopper 400 and changing the tilt angle of the hopper 400, which facilitates the loading and unloading of waste rock. Among them, the hopper 400, which is rotatably connected to the blocking block 600 and has a telescopic tube in the middle, can be easily adjusted to different tilt angles, reducing the splashing of waste rock from the lower end of the hopper 400 to the outside and improving the adaptability of the hopper 400 angle.
[0032] Example 2: Figure 1 , Figure 2 and Figure 7 As shown, based on Embodiment 1, the support leg assembly 300 includes a connecting block 301. Two first columns 302 are rotatably connected to both ends of the connecting block 301. The lower ends of the first columns 302 are connected to second columns 304 by fastening bolts 303. Multiple second columns 304 are provided, and two adjacent second columns 304 are connected and fixed by fastening bolts 303. Multiple second columns 304 are connected to the lower ends of the first columns 302 by fastening bolts 303. By installing an appropriate number of second columns 304, the conveyor belt 100 can be adjusted to a suitable tilt angle.
[0033] An electric drive wheel 305 is installed on the bottom surface of the second column 304 located at the lower end. A pin 306 is rotatably connected to the side wall of the first column 302. Multiple rotating shafts 307 are fixed on one of the support plates 200. A support 308 is rotatably connected to the outer peripheral wall of the rotating shaft 307. A third hydraulic cylinder 309 is installed on the support 308. The piston rod of the third hydraulic cylinder 309 is fixedly connected to the pin 306. The extension and retraction of the piston rod drives the first column 302 to rotate around the connecting block 301, changing the tilt angle of the first column 302, so as to facilitate timely adjustment of the height of the conveyor belt 100.
[0034] In use, the conveyor frame is moved around the work site by the electric drive wheel 305 to achieve flexible adjustment of the equipment position; when it is necessary to adjust the height of the conveyor frame, the piston rod of the third hydraulic cylinder 309 extends and retracts. Since the piston rod is fixedly connected to the pin 306 on the side wall of the first column 302, and the first column 302 is rotatably connected to the support leg connection point of the conveyor belt 100 through the connecting block 301, the extension and retraction of the piston rod drives the first column 302 to rotate around the connecting block 301, thereby changing the tilt angle of the first column 302. Meanwhile, the lower end of the first column 302 is connected to multiple second columns 304 via fastening bolts 303. By installing an appropriate number of second columns 304, the conveyor belt 100 can be adjusted to a suitable tilt angle. When the angle of the first column 302 changes, it drives the height of the support leg assembly 300 to change, thereby realizing the adjustment of the overall tilt angle of the conveyor frame. By removing and installing the fastening bolts 303, the second columns 304 can be added or removed to further adjust the height of the support leg assembly 300, which improves the flexibility and efficiency of the equipment, realizes multi-level height adjustment, broadens the application range of the conveyor frame, and reduces the problems of inconvenience and inefficiency caused by height mismatch.
