[0019] The following is combined with Figure 1-2 This application is described in further detail.
[0020] The embodiment of the present application discloses a dust prevention device for the loading process. Figure 1 The dust-proof device used in the feeding process includes a belt conveyor 1, a hopper 2 and a dust cover 3, wherein the belt conveyor 1 has a frame 101; the hopper 2 is mounted on the frame 101 through a bracket 12, and the hopper 2 is located above the feeding end of the belt conveyor 1. The dust cover 3 is arranged at the upper end of the frame 101. The cross section of the dust cover 3 is door-shaped. The dust cover 3 extends along the conveying direction of the belt conveyor 1. The conveyor belt of the belt conveyor 1 is located in the dust cover 3. The length of the dust cover 3 is greater than the length of the conveyor belt of the belt conveyor 1. The depth of the dust cover 3 is 30 cm, and the hopper 2 is passed through the dust cover 3.
[0021] During loading, sand, gravel, dry sand and other raw materials are put into the loading hopper 2 through the excavator, and the sand, gravel, dry sand and other raw materials fall onto the conveying belt of the belt conveyor 1 through the loading hopper 2, and can be transported through the conveying belt. Since the dust cover 3 is arranged above the conveying belt of the belt conveyor 1, on the one hand, it helps to block the dust and scattering caused by sand, gravel, dry sand and other raw materials falling onto the belt conveyor 1. On the other hand, the dust cover 3 has the function of shielding against wind and rain, so that the sand, gravel, dry sand and other raw materials on the conveying belt of the belt conveyor 1 are not easily affected by wind and dust generation during the material pulling process, thereby preventing air pollution to a certain extent.
[0022] Reference Figure 1 In the embodiment of the present application, the dust cover 3 is made of one of a steel plate, a stainless steel plate, and an aluminum alloy plate, without limitation, to provide good stability. In other embodiments, the dust cover 3 may be a combination of multiple support rods and a polyvinyl chloride tarpaulin. The multiple support rods are arranged on the frame 101 at intervals along the conveying direction of the belt conveyor 1. The polyvinyl chloride tarpaulin is covered on the multiple support rods to cover the conveyor belt of the belt conveyor 1. The upper hopper 2 is installed on the polyvinyl chloride tarpaulin.
[0023] Reference Figure 1Specifically, the dust cover 3 includes a first cover body 31 and a second cover body 32. The first cover body 31 is located on the side of the upper hopper 2 close to the feed end of the belt conveyor 1, and the second cover body 32 is located on the side of the upper hopper 2 close to the discharge end of the belt conveyor 1. The first cover body 31 and the second cover body 32 are both detachably connected to the frame 101 by screws, bolts, rivets, etc. The sides of the first cover body 31 and the second cover body 32 that are close to each other abut against each other to completely cover the belt conveyor 1.
[0024] Reference 1 and Figure 2 The first cover 31 and the second cover 32 are each provided with a notch 8 on one side thereof, and the notches 8 on the first cover 31 and the second cover 32 are joined to form a through hole for the upper hopper 2 to pass through. The first cover 31 and the second cover 32 are detachably mounted on the frame 101, so that the dust cover 3 can be removed from the frame 101 for easy maintenance and inspection of the belt conveyor 1.
[0025] Reference Figure 1 and Figure 2 Dust shield groups 4 are provided on both opposite sides of the second cover body 32. The dust shield groups 4 are located on the side of the upper hopper 2 close to the discharge end of the belt conveyor 1. Each group of dust shield groups 4 includes multiple dust shield plates 41 passing through the top wall of the second cover body 32. The multiple dust shield plates 41 of each group of dust shield groups 4 are arranged at intervals along the conveying direction of the belt conveyor 1, and the multiple dust shield plates 41 in the two groups of dust shield groups 4 are staggered with each other.
[0026] The dust generated when the raw materials fall from the upper hopper 2 onto the belt conveyor 1 will spread along the length direction of the second cover body 32. The multiple dust shields 41 are staggered to extend the dust spreading path, making it difficult for the dust to drift out from the side of the second cover body 32 close to the discharge end of the belt conveyor 1, thereby helping to prevent air pollution.
[0027] Reference Figure 1 and Figure 2 The dust guard plate 41 is slidably arranged on the top wall of the second cover body 32, and the sliding direction of the dust guard plate 41 is perpendicular to the conveying direction of the belt conveyor 1. The second cover body 32 is provided with an adjusting member 5 for adjusting multiple dust guard plates 41 to slide synchronously toward or away from the belt conveyor 1; in order to facilitate the adjustment of multiple dust guard plates 41 to slide synchronously toward or away from the belt conveyor 1, the adjusting member 5 includes a screw 51 and a connecting plate 52. The screw 51 is rotatably arranged on the top wall of the second cover body 32, and the rotation axis of the screw 51 is parallel to the sliding direction of the dust guard plate 41. The connecting plate 52 is threadedly sleeved on the screw 51. The connecting plate 52 is located on the side of the second cover body 32 away from the belt conveyor 1, and each dust guard plate 41 is fixedly connected to the connecting plate 52 on the side outside the second cover body 32.
[0028] When the conveyed raw materials can be piled up higher on the belt conveyor 1, the screw 51 is rotated so that the screw 51 drives the connecting plate 52 to move in the direction away from the belt conveyor 1, thereby driving the dust guard plate 41 away from the belt conveyor 1, so that the dust guard plate 41 is not likely to block the conveyed raw materials; when the conveyed raw materials are not easy to pile up on the belt conveyor 1, the screw 51 is rotated so that the screw 51 drives the connecting plate 52 to move in the direction close to the belt conveyor 1, thereby driving the dust guard plate 41 close to the conveying belt of the belt conveyor 1, so that the dust guard plate 41 does not interfere with the conveyed raw materials while ensuring the dust blocking effect.
[0029] Reference Figure 1 and Figure 2 A baffle 6 is slidably provided on the first cover body 31. The sliding direction of the baffle 6 is perpendicular to the conveying direction of the belt conveyor 1. A cushion layer is fixed on the surface of the baffle 6, so that there is friction between the baffle 6 and the first cover body 31, and the baffle 6 is not prone to unnecessary sliding. The baffle 6 is located on the side of the upper hopper 2 away from the discharge end of the belt conveyor 1, and the side of the baffle 6 located inside the first cover body 31 is close to the conveyor belt at the feed end of the belt conveyor 1. On the one hand, the setting of the baffle 6 can block the dust splashed by raw materials such as sand and gravel and dry sand falling on the belt conveyor 1, thereby improving the dust prevention effect; on the other hand, it can prevent the scattering of raw materials such as sand and gravel and dry sand falling on the belt conveyor 1, so that the raw materials are not easily dropped outside the belt conveyor 1, and to a certain extent prevent the pollution of the platform.
[0030] Reference Figure 1 Two windshields 7 are relatively fixed to one side of the second housing 32 near the discharge end of the belt conveyor 1. The two windshields 7 are arranged perpendicular to the conveying direction of the belt conveyor 1. The two windshields 7 are located on opposite sides of the belt conveyor 1 and extend downward. The installation of the windshields 7 can prevent the sand, gravel, dry sand, and other raw materials discharged from the discharge end of the belt conveyor 1 from being affected by wind and generating dust.
[0031] Reference Figure 1 and Figure 2 The lower side of the second cover body 32 is detachably connected to the bottom cover 10 by bolts, screws, rivets, etc. The cross-section of the bottom cover 10 is U-shaped. The conveyor belt of the belt conveyor 1 is located between the second cover body 32 and the bottom cover 10. Specifically, the depth of the bottom cover 10 is 30 cm. A limit plate 11 is fixed to the side of the bottom cover 10 close to the feed end of the belt conveyor 1.
[0032] The setting of the bottom cover 10 can seal the gap between the conveyor belt of the belt conveyor 1 and the dust cover 3, thereby completely wrapping the conveyor belt of the belt conveyor 1, and the setting of the bottom cover 10 and the limiting plate 11 can collect the raw materials scattered in the gap between the conveyor belt of the belt conveyor 1 and the dust cover 3, thereby avoiding platform pollution to a certain extent.
[0033] The implementation principle of the embodiment of the present application is: when loading, sand, gravel, dry sand and other raw materials are put into the loading hopper 2 through the excavator, and the sand, gravel, dry sand and other raw materials fall onto the conveying belt of the belt conveyor 1 through the loading hopper 2, and the raw materials are transported by the conveying belt; because the dust cover 3 is arranged above the conveying belt of the belt conveyor 1, it is blocked by the baffle 6 and the multiple dust shields 41, which helps to prevent the sand, gravel, dry sand and other raw materials from falling onto the belt conveyor 1 and the dust splashed and dispersed. At the same time, the dust cover 3 has the function of shielding against wind and rain, so that the sand, gravel, dry sand and other raw materials on the conveying belt of the belt conveyor 1 are not easily affected by wind and generate dust during the pulling process, thereby preventing air pollution to a certain extent.
[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
