Description

Technical Field

[0001] This utility model relates to the field of engineering transportation technology, specifically to a dust prevention device for earthmoving vehicles. Background Technology

[0002] Earthmoving vehicles are special vehicles used in engineering construction and earthwork projects. They are mainly used to transport earth and rock materials from the excavation site to the filling or stockpiling location. As an important tool in the construction industry, they play a vital role in engineering construction.

[0003] When earthmoving trucks are transporting sand and gravel, the bumps or strong winds can cause the soil and gravel inside the truck to be kicked up. When the wind comes into contact with the earthmoving truck, it can cause the dust inside the truck to be kicked up, affecting the environment along the roadside. When the truck dumps the ash at the designated location, the dust can be stirred up too much during the dumping process if there are no obstructions or restrictions, which can affect the air environment at the construction site. Utility Model Content

[0004] To solve the above-mentioned technical problems, a dust prevention device for earthmoving vehicles is provided. This technical solution addresses the issues raised in the background art by establishing a shielding and protective mechanism. During transportation, the dust cover and sealing plate work together to shield and protect the dust raised inside the transport container. When unloading soil into the transport vehicle, the sealing plate and the arc-shaped limiting plate work together to shield and protect the raised dust. This facilitates the sealing and shielding of soil and rocks during transportation, preventing dust from flying everywhere due to wind during transportation, and limiting and shielding the dust raised by soil and rocks when unloading.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dust prevention device for earthmoving vehicles, including a transport box;

[0007] The shielding and protective mechanism includes a sealing plate located at one end of the transport box and a dust cover located at the top of the transport box. A shaft is fixedly connected to the top of the sealing plate, and a set of arc-shaped limiting plates are symmetrically fixedly connected to one end of the sealing plate.

[0008] Preferably, the inner side of the dust-proof cloth is provided with a dust-proof cloth folding mechanism. The dust-proof cloth folding mechanism includes a fixed support plate located at one end of the inner side of the dust-proof cloth and a second support plate located at the other end of the inner side of the dust-proof cloth. Multiple first support plates are equidistantly distributed between the fixed support plate and the second support plate. A guide slider is snapped into the bottom end of the fixed support plate, the first support plate and the second support plate. A guide groove is opened on one side and the other side of the transport box. The guide slider is located inside the guide groove and is slidably connected to the guide groove. Multiple clamping cavities are equidistantly opened at one end of the top of the transport box.

[0009] Preferably, a clamping plate is snapped onto one side of the fixed support plate, and a plurality of clamping blocks are fixedly connected at equal intervals to one end of the clamping plate, and the clamping blocks can be snapped onto the clamping cavity.

[0010] Preferably, a fixing rod extends through the other end of the top of the transport box, a positioning column is slidably connected to the outside of the fixing rod, the positioning column is connected through to the shaft, and the positioning column is slidably connected to the shaft. Multiple positioning teeth are fixedly connected at equal intervals on the inner cavity wall of the shaft, and an earthmoving vehicle is provided at the bottom of the transport box.

[0011] Preferably, the positioning column has a set of tooth grooves that match the positioning tooth block, and the positioning tooth block can be engaged with the tooth grooves.

[0012] Preferably, an adjusting nut is rotatably connected to one side of the fixing rod, a push-adjustment U-plate is provided on one side of the positioning column rod, the adjusting nut is connected through the middle of one side of the push-adjustment U-plate, and a pull-out cavity is provided at the bottom end of one side of the positioning column rod, and the push-adjustment U-plate is slidably connected to the pull-out cavity.

[0013] Preferably, a docking groove is provided at the connection position between the fixed support plate and the clamping plate, and a docking head is clamped on the inner side of the docking groove, with one side of the docking head being fixedly connected to the clamping plate.

[0014] Compared with the prior art, this utility model provides a dust prevention device for earthmoving vehicles, which has the following beneficial effects: it facilitates the sealing and protection of earth and stone during the transportation process, helps prevent dust from flying everywhere due to wind force during transportation, and facilitates the limiting and blocking of dust raised by earth and stone when dumping.

[0015] The protective shielding mechanism, through the cooperation of the dust-proof cloth and the sealing plate, protects the dust raised inside the transport container during transportation. When unloading the soil into the transport vehicle, the sealing plate and the arc-shaped limiting plate work together to protect the raised dust. This facilitates the sealing and protection of soil and rocks during transportation, helps prevent dust from flying everywhere due to wind force during transportation, and makes it easier to limit and block the dust raised by soil and rocks when unloading.

[0016] The system comprises an adjusting nut, a push-adjustment U-plate, a pull-out cavity, a positioning column, a shaft, positioning teeth, and a toothed groove assembly. When dumping soil, rotating the adjusting nut causes the push-adjustment U-plate, connected to the outside, to slide linearly to one side under the constraint of the pull-out cavity. As the U-plate slides to one side, it causes the positioning column, fixedly connected to the other side, to slide to one side under the constraint of the fixed rod. This causes the toothed groove assembly on the positioning column to slide synchronously to one side, separating from the positioning teeth fixed to the inner wall of the shaft. At this point, pushing the sealing plate to one end causes the sealing plate to rotate around the positioning toothed groove under the constraint of the shaft fixedly connected to the top. The column is rotated 90 degrees to one end, and then the adjusting nut is rotated in the opposite direction, which causes the push-adjustment U-plate to slide in a straight line in the opposite direction under the restriction of the pull-out cavity. This pushes the positioning column fixedly connected to one side of the push-adjustment U-plate to slide to one side under the guidance of the inner cavity wall of the shaft. This causes the toothed groove group on the positioning column to slide and lock onto the positioning tooth block fixed on the inner cavity wall of the shaft, preventing the shaft from changing angle after adjustment. This fixes the position of the sealing plate fixedly connected to one end of the shaft after adjustment, which facilitates the adjustment of the angle of the sealing plate as needed and makes it convenient to block the dust raised when dumping soil.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] Please refer to Figure 1 , Figure 2 and Figure 5 As shown, a dust prevention device for earthmoving vehicles includes a transport box 2;

[0026] The shielding and protective mechanism includes a sealing plate 7 located at one end of the transport box 2 and a dust cover 5 located at the top of the transport box 2. A shaft 6 is fixedly connected to the top of the sealing plate 7, and a set of arc-shaped limiting plates are symmetrically fixedly connected to one end of the sealing plate 7.

[0027] In this embodiment, during transportation, the dust cover 5 and the sealing plate 7 work together to cover and protect the dust raised inside the transport box 2. When unloading the dust into the transport vehicle, the sealing plate 7 and the arc-shaped limiting plate work together to cover and protect the dust raised.

[0028] Example 2

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a dust-covering cloth 5 has a dust-covering cloth folding mechanism on its inner side. The dust-covering cloth folding mechanism includes a fixed support plate 17 located at one end of the inner side of the dust-covering cloth 5 and a second support plate 14 located at the other end of the inner side of the dust-covering cloth 5. Multiple first support plates 11 are equidistantly distributed between the fixed support plate 17 and the second support plate 14. A guide slider 4 is snapped into the bottom end of the fixed support plate 17, the first support plate 11, and the second support plate 14. A guide groove 3 is opened on one side and the other side of the transport box 2. The guide slider 4 is located inside the guide groove 3 and is slidably connected to the guide groove 3. Multiple clamping cavities 1 are equidistantly opened at one end of the top of the transport box 2. 2. A clamping plate 18 is snapped onto one side of the fixed support plate 17. Multiple clamping blocks 19 are fixedly connected at equal intervals to one end of the clamping plate 18. The clamping blocks 19 can be snapped onto the clamping cavity 12. A docking groove is provided at the connection position between the fixed support plate 17 and the clamping plate 18. A docking head 20 is clamped on the inner side of the docking groove. One side of the docking head 20 is fixedly connected to the clamping plate 18. A magnetic strip is sewn onto one end of the dust cover 5 near the guide slide 3. When the dust cover 5 is unfolded, one end of the dust cover 5 can be firmly adsorbed onto the transport box 2 to prevent dust from leaking out through the gap between the dust cover 5 and the transport box 2 and improve the sealing performance of the unfolded dust cover 5.

[0030] In this embodiment, when loading soil, the second support plate 14 is pushed to one end. Under the constraint of the guide slider 4 engaged at the bottom, the second support plate 14 slides along the guide groove 3 to one end, thereby causing the dust cover 5 between the second support plate 14 and the first support plate 11 at one end to cover the dust cover 5. When the second support plate 14 slides to one end and contacts the first support plate 11, it will push the first support plate 11 to slide along the guide groove 3 to one end a specified distance under the constraint of the guide slider 4 to cover the dust cover 5 laid on it. When the first support plate 11 slides to one end and contacts the fixed support plate 17, the folding of the dust cover 5 is completed. At this time, soil and stones can be loaded into the transport box 2. After loading the soil and stones, the second support plate 14 and the first support plate 11 are slid to the other end. The second support plate 14 and the first support plate 11 will slide along the guide groove 3 to the other end under the constraint of the corresponding guide slider 4. When the bottom of one end of the second support plate 14 slides and engages with the shaft 6, the unfolding process of the dust cover 5 is completed.

[0031] When installing the dust cover 5, slide the corresponding number of guide sliders 4 into the guide grooves 3 in sequence. Then, snap the fixed support plate 17, the first support plate 11, and the second support plate 14 onto the corresponding guide sliders 4. Snap the clamp plate 18 between a set of fixed support plates 17, so that the mating head 20 fixedly connected to the clamp plate 18 snaps into the mating groove opened on the fixed support plate 17. Then, use the fixing nut 10 to seal the bottom end of one side of the fixed support plate 17, thereby fixing the installed fixed support plate 17 and preventing the clamp plate 18 from slipping out of the fixed support plate 17. Separate from the fixed support plate 17, then clip one end of the dust cover 5 onto the multiple clamping blocks 19 fixedly connected to one end of the clamping plate 18, push the clamping plate 18 to one end, so that the multiple clamping blocks 19 fixedly connected to one end of the clamping plate 18 slide and clip into the clamping cavity 12, so that one end of the dust cover 5 is clamped and fixed in the clamping cavity 12, and then spread the dust cover 5 onto the first support plate 11 and the second support plate 14 and fix the contact position with the fixing nut to prevent the dust cover 5 from separating from the first support plate 11 and the second support plate 14.

[0032] Example 3

[0033] Please refer to Figure 1 , Figure 2 and Figure 5 As shown, a fixed rod 13 passes through the other end of the top of the transport box 2. A positioning rod 15 is slidably connected to the outside of the fixed rod 13. The positioning rod 15 is connected through the shaft 6 and is slidably connected to the shaft 6. Multiple positioning teeth 21 are fixedly connected at equal intervals on the inner cavity wall of the shaft 6. An earthmoving vehicle 1 is provided at the bottom of the transport box 2. A set of tooth grooves matching the positioning teeth 21 is provided on the positioning rod 15. The positioning teeth 21 can be engaged with the tooth grooves. An adjusting nut 9 is rotatably connected to one side of the fixed rod 13. A push-adjustment U-plate 8 is provided on one side of the positioning rod 15. The adjusting nut 9 is connected through the middle of one side of the push-adjustment U-plate 8. A pull-out cavity 16 is provided at the bottom of one side of the positioning rod 15. The push-adjustment U-plate 8 is slidably connected to the pull-out cavity 16. A corrugated dustproof tube is provided on the outside of the adjusting nut 9 for dust protection.

[0034] In this embodiment, when dumping soil, rotating the adjusting nut 9 causes the outerly connected push-adjustment U-plate 8 to slide linearly to one side under the constraint of the pull-out cavity 16. As the push-adjustment U-plate 8 slides to one side, it causes the positioning column 15, which is fixedly connected to the other side, to slide to one side under the constraint of the fixing rod 13. This causes the toothed grooves on the positioning column 15 to slide synchronously to one side and separate from the positioning toothed block 21 fixed on the inner wall of the shaft 6. At this time, pushing the sealing plate 7 to one end causes the sealing plate 7 to rotate 90 degrees around the positioning column 15 under the constraint of the shaft 6 fixedly connected to the top. The adjusting nut 9 is rotated in the reverse direction, causing the push-adjustment U-plate 8 to slide linearly in the opposite direction under the restriction of the pull-out cavity 16. This pushes the positioning column rod 15, which is fixedly connected to one side of the push-adjustment U-plate 8, to slide to one side under the guidance of the inner cavity wall of the shaft rod 6. This causes the toothed groove group on the positioning column rod 15 to slide and lock onto the positioning tooth block 21 fixed on the inner cavity wall of the shaft rod 6, preventing the shaft rod 6 from changing angle after adjustment. This fixes the position of the sealing plate 7, which is fixedly connected to one end of the shaft rod 6 after adjustment. When dumping soil, the dust raised is blocked by the sealing plate 7, preventing the dust from continuing to float upward.

[0035] The working principle and usage of this device are as follows: When loading soil, push the second support plate 14 to one end. Under the constraint of the guide slider 4 engaged at the bottom, the second support plate 14 will slide along the guide groove 3 to one end, thereby causing the dust-proof cloth 5 between the second support plate 14 and the first support plate 11 at one end to cover the dust-proof cloth 5. When the second support plate 14 slides to one end and contacts the first support plate 11, it will push the first support plate 11 to slide a specified distance along the guide groove 3 under the constraint of the guide slider 4, thus covering the dust-proof cloth 5 laid on it. When the first support plate 11 slides to one end and contacts the fixed support plate 17, the folding of the dust-proof cloth 5 is completed. Stack the soil and stones, then load the transport box 2 with soil and stones. After loading, slide the second support plate 14 and the first support plate 11 to the other end. The second support plate 14 and the first support plate 11 will slide along the guide groove 3 to the other end under the restriction of the corresponding guide slider 4. When the bottom of one end of the second support plate 14 slides and locks onto the shaft 6, rotate the sealing plate 7 ninety degrees, so that the sealing plate 7 rotates and locks onto one end of the transport box 2, forming a sealing baffle to prevent dust from falling out of the transport box 2 during transportation. When dumping soil, rotate the adjusting nut 9. The adjusting nut 9 will drive the outerly connected push-adjustment U plate 8 to move straight to one side under the restriction of the pull-out cavity 16. When the U-plate 8 slides to one side, it will cause the positioning rod 15, which is fixedly connected to the other side, to slide to one side under the restriction of the fixing rod 13. This will cause the toothed grooves on the positioning rod 15 to slide to one side synchronously and separate from the positioning tooth block 21 fixed on the inner cavity wall of the shaft 6. At this time, the sealing plate 7 is pushed to one end. The sealing plate 7 will rotate 90 degrees around the positioning rod 15 under the restriction of the shaft 6 fixedly connected to the top. Then, the adjusting nut 9 is rotated in the opposite direction, which will cause the U-plate 8 to slide in a straight line in the opposite direction under the restriction of the pull-out cavity 16. This will push the positioning rod 15, which is fixedly connected to one side of the U-plate 8, to slide in a straight line under the restriction of the inner cavity wall of the shaft 6. The shaft slides downwards to one side, causing the toothed grooves on the positioning rod 15 to slide and engage with the positioning toothed block 21 fixed on the inner cavity wall of the shaft 6. This prevents the adjusted shaft 6 from changing angle, thus fixing the position of the sealing plate 7 fixedly connected to one end of the shaft 6. The hydraulic cylinder at the bottom of the transport box 2 pushes the transport box 2 to rotate at a certain angle. The soil and rocks inside the transport box 2 will slide to one end along the tilt angle of the transport box 2. When the soil and rocks slide out of the transport box 2 along the tilt angle, the sealing plate 7 and the arc-shaped limiting plate work together to shield and protect the dust raised, preventing the dust from continuing to float upwards.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
