Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology for mines, specifically a mobile windbreak and dust suppression net for open-pit mine truck unloading pits. Background Technology
[0002] Windbreak and dust suppression nets utilize aerodynamic principles to create upward and downward interfering airflows on the inner side of the netting when strong winds pass through it. This achieves the effect of strong winds on the outside and weak winds or even no winds on the inside, thus preventing dust from flying. Therefore, these dust suppression nets are often used in open-pit mining, sand and gravel processing, and other fields that easily generate large amounts of dust. In open-pit mining operations, trucks generate a lot of dust when unloading materials at the unloading pit. To prevent dust from harming the environment, windbreak and dust suppression nets are used for dust suppression.
[0003] However, existing dust suppression nets are usually installed at a fixed height, making it difficult to flexibly adjust the height according to actual dust suppression needs. Furthermore, the entire installation process is cumbersome and not simplified enough, which is not conducive to the rapid deployment and maintenance of the equipment.
[0004] Therefore, it is necessary to provide a new type of mobile windbreak and dust suppression net for open-pit mine truck unloading pits to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figures 1-6 The mobile windbreak and dust suppression net for open-pit mine truck unloading pits includes: a loading base 1 and two bottom-contacting support legs 2 fixedly installed at the bottom of the loading base 1. A first side support 7 and a second side support 8 are bolted to the top of the loading base 1. After installation, the two sides of the loading base 1 are perpendicularly aligned with the opposite ends of the first side support 7 and the second side support 8. Both the first side support 7 and the second side support 8 have planar grooves 17, with openings on the sides of the two planar grooves 17 that are close to each other. A space is provided between the first side support 7 and the second side support 8. A dust suppression mesh plate 9 is provided, the height of which is the same as the height of the first side support 7 and the second side support 8, to ensure that there is virtually no gap between the upper and lower dust suppression mesh plates 9 when the first side support 7 and the second side support 8 are stacked on top of each other. A convex fixing shell 18 is fixedly installed on both sides of the dust suppression mesh plate 9, with the protruding parts of the two convex fixing shells 18 located in two planar grooves 17 respectively. Adaptor grooves 15 are provided at the top and bottom of both the first side support 7 and the second side support 8, and connecting sheet metal 16 is fixedly installed in the two upper adapter grooves 15 by screws. The top of the connecting sheet metal 16 protrudes from the adapter groove 15. When the first side support 7 and the second side support 8 are installed upwards, the protruding part can extend to the adapter groove 15 on the previous first side support 7 or second side support 8, and then be fixed with screws to achieve a fixed connection between the two first side supports 7 or the two second side supports 8. A snap-fit groove 10 is provided on the side of the first side support 7 away from the second side support 8, and a snap-fit strip 11 is fixedly installed on the side of the second side support 8 away from the first side support 7. The snap-fit strip 11 is adapted to the snap-fit groove 10. This allows the snap-fit strip 11 of one set of dust suppression mechanism units to snap into the snap-fit groove 10 of the adjacent set of dust suppression mechanism units, making the two sets of dust suppression mechanism units seamlessly connected and ensuring the dust suppression effect. The first side support 7 and the second side support 8 are provided with a length adjustment mechanism to adjust the distance between the first side support 7 and the second side support 8. The loading base 1 is provided with a moving unit to flexibly adjust the position of the dust suppression mesh plate 9. The two convex fixed shells 18 are provided with a connecting mechanism to fix the two convex fixed shells 18 to the first side support 7 and the second side support 8 respectively.
[0023] The aforementioned mobile unit includes a built-in groove 3 at the bottom of the loading base 1. Two hydraulic outriggers 4 are fixedly installed in the built-in groove 3. The same mounting base 5 is fixedly installed on the output shaft of the two hydraulic outriggers 4. Four casters 6 are fixedly installed at the bottom of the mounting base 5. By extending the output shaft of the hydraulic outriggers 4, the casters 6 can be grounded and the bottom-touching outriggers 2 can be lifted up, facilitating overall movement.
[0024] The aforementioned length adjustment mechanism includes a connecting arm 12 fixedly installed on one side of the first side support 7, and a long strip hollow shell 13 fixedly installed on one side of the second side support 8. One side of the connecting arm 12 extends into the long strip hollow shell 13 and slides in connection with one side of the long strip hollow shell 13. A fastening screw 14 is threaded onto the long strip hollow shell 13, and the end of the fastening screw 14 abuts against the connecting arm 12. The distance between the first side support 7 and the second side support 8 can be quickly adjusted by utilizing the sliding relationship between the connecting arm 12 and the long strip hollow shell 13.
[0025] The aforementioned connecting mechanism includes two countersunk holes 19, which are respectively opened on the top inner walls of two planar grooves 17. Hydraulic cylinders 20 are fixedly installed on the top inner walls of two convex fixed shells 18. A positioning lever 21 is fixedly installed on the output shaft of each of the two hydraulic cylinders 20. The top ends of the two positioning levers 21 are inserted into the two countersunk holes 19, and the two positioning levers 21 are slidably connected to the protruding parts of the two convex fixed shells 18. This slidable connection involves sliding holes opened at the top of the protruding parts of the two convex fixed shells 18. The two positioning levers 21 pass through the two sliding holes and contact the inner walls of the corresponding sliding holes. By extending and retracting the output shaft of the hydraulic cylinders 20, the two convex fixed shells 18 can be quickly installed on the first side support 7 and the second side support 8, or the installation connection can be quickly removed, facilitating the removal of the dust suppression screen 9.
[0026] In addition, in this method, diagonal braces are fixedly installed on one side of the first side support 7 and the second side support 8 by bolts, which has a stabilizing effect. Furthermore, the selection of these diagonal braces can be based on the final stacking height of the first side support 7 and the second side support 8, making them more flexible in use.
[0027] The actual installation operation of the mobile windbreak and dust suppression net for open-pit mining truck unloading pits provided by this utility model is as follows:
[0028] First, start the output shaft of the hydraulic outrigger 4 to extend, so that the four fusible wheels 6 touch the ground and lift the bottom outrigger 2. Then move the loading base 1. After moving the loading base 1 to the designated dust suppression position, start the output shaft of the hydraulic outrigger 4 to retract, so that the bottom outrigger 2 touches the ground again.
[0029] Then, take out one pair of first side supports 7 and second side supports 8, and install them on the top of the loading base 1. After installation, the mutually distant sides of the first side supports 7 and second side supports 8 are vertically aligned with the two sides of the loading base 1. Then, take out the dust suppression screen 9, and start the output shafts of the two hydraulic cylinders 20 to extend, so that the two inserting folding rods 21 enter the convex fixing shell 18. Then, the protruding parts on the convex fixing shell 18 on both sides of the dust suppression screen 9 are respectively locked in the two planar grooves 17. Then, start the output shafts of the hydraulic cylinders 20 to retract, and bring the two inserting folding rods 21 into the two inserting countersunk holes 19 respectively. This completes the installation of one dust suppression screen 9.
[0030] Next, take out the corresponding number of first side supports 7 and second side supports 8 according to the actual required dust suppression height. Then, place the next set of first side supports 7 and second side supports 8 on top of the fixed first side supports 7 and second side supports 8, and use the connecting sheet metal 16 to fix the upper and lower first side supports 7 and the upper and lower second side supports 8. Then, install the remaining first side supports 7 and second side supports 8 in this way from bottom to top. After installation to the specified height, install the dust suppression mesh 9 in the same way as described above between the corresponding first side supports 7 and second side supports 8 until the installation is completed. Then, it can be put into dust suppression use. The diagonal brace can be selected according to the stacking height of the dust suppression mesh 9 to select an appropriate length of diagonal brace. Finally, install it on the highest first side support 7 and second side support 8.
[0031] Furthermore, in subsequent use, when it is necessary to install dust suppression mesh panels 9 of different lengths, on the one hand, it is necessary to select the corresponding length of the loading base 1, and then adjust the distance between the first side support 7 and the second side support 8 according to the length of the loading base 1. When adjusting, simply rotate the top screw 14 in the opposite direction to separate it from the connecting arm 12, and then move the first side support 7 away from the second side support 8 until the distance between the two reaches the specified length, and then tighten the top screw 14.
[0032] In addition, in subsequent use, in order to increase the overall dust suppression width, the dust suppression mechanism installed above can be used as a unit to continue to assemble multiple dust suppression mechanism units. Then, the snap-fit strip 11 on one dust suppression mechanism unit is snapped into the snap-fit groove 10 on another dust suppression mechanism unit, so that the two dust suppression mechanism units are seamlessly spliced. After that, multiple dust suppression mechanism units can be spliced in the same way as described above.
[0033] Compared with related technologies, the mobile windbreak and dust suppression net for open-pit mine truck unloading pits provided by this utility model has the following beneficial effects:
[0034] This utility model provides a mobile windbreak and dust suppression net for open-pit mining truck unloading pits. Through the set mobile unit, the loading base 1 can quickly adjust the dust suppression position of the dust suppression net plate 9 according to actual needs, so that it can be adjusted according to the unloading position. In addition, through the setting of the first side support 7 and the second side support 8, a certain number of the first side support 7 and the second side support 8 can be used for installation according to the dust suppression height, which is convenient to adjust the dust suppression height and has a high degree of flexibility. Furthermore, when fixing the dust suppression net plate 9, it is only necessary to push the convex fixing shell 18 into the flat groove 17, and then start the hydraulic cylinder 20 to bring the embedded bending rod 21 into the embedded countersunk hole 19. The installation steps are few and relatively quick.
