[0017] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages:

[0018] 1. The utility model generates an adsorption force through the input end of the dust extraction blower by setting a dust removal mechanism, and through the cooperation of the dust extraction pipe and the corrugated pipe, the adsorption force is conducted into the inner cavity of the concrete mixing tank, and the dust in the inner cavity of the concrete mixing tank is adsorbed. Subsequently, the dust enters the exhaust pipe through the corrugated pipe, the dust extraction pipe and the output end of the dust extraction blower. At this time, the dust enters the inner cavity of the dust collection box through the exhaust pipe, and the water source is conducted into the atomizing spray water tank through the water inlet pipe. The atomizing spray water tank atomizes and sprays the water source into the dust collection box to wet the dust in the dust collection box. Subsequently, through the output of the drainage pump, the sewage in the inner cavity of the dust collection box is discharged into the drainage pipe to complete the cleaning of the sewage, thereby completing the dust removal work of the entire equipment. This effectively avoids the situation that when the concrete mixing tank stirs the concrete inside it, a large amount of dust is generated due to the stirring, causing the dust to float in the surrounding air, which may lead to the operator inhaling these dusts and affecting the health of the operator. By setting the output of the motor, the driving synchronous shaft drives the synchronous transmission belt to rotate. At this time, the driven synchronous shaft rotates, causing the lead screw to rotate. At this time, the nut block drives the connecting rod and the dust extraction cover plate to move downward. By adjusting the height of the dust extraction cover plate, it is convenient to carry out dust removal work on concrete mixing tanks with different heights of capacity, thereby increasing the range of dust removal that the entire dust removal mechanism can perform and facilitating the operator's use.

[0019] 2. The utility model can make the dust extraction cover plate and the concrete mixing tank be connected to each other by setting a thread groove and a fixing bolt, improving the sealing performance when the dust extraction cover plate is connected to the concrete mixing tank and avoiding the leakage of dust during the dust suction work. By setting a limit groove, the movement of the nut block can be limited to prevent the nut block from shifting during movement, thereby affecting the adjustment work of the height of the dust extraction cover plate and restricting the dust suction range of the entire dust removal mechanism, which affects the operator's use. By setting anchor bolts, the overall equipment can be stabilized to prevent the entire equipment from tipping over due to accidental collision, thus affecting the normal dust removal work of the equipment.

Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0030] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0031] Embodiment 1

[0032] AsFigure 1-6 As shown in the figure, an embodiment of the utility model provides a dust removal device for asphalt concrete production, including a support frame 1 and a concrete mixing tank 9. An installation frame 4 is fixedly installed at the top of the support frame 1. A chute 7 is opened on the front side of the support frame 1. A sliding plate 8 is slidably connected in the inner cavity of the chute 7. The concrete mixing tank 9 is fixedly installed on the top of the sliding plate 8. A one-way air inlet valve 12 is fixedly installed on the front side of the concrete mixing tank 9;

[0033] A dust removal mechanism 2 is arranged at the top of the installation frame 4. The dust removal mechanism 2 includes a dust extraction blower 201. An input end of the dust extraction blower 201 is communicated with a dust extraction pipe 202. An output end of the dust extraction blower 201 is communicated with an exhaust pipe 204. One end of the dust extraction pipe 202 away from the dust extraction blower 201 is communicated with a corrugated pipe 203. A dust collection box 205 is fixed on the left side of the top of the installation frame 4. An atomizing spray water tank 207 is fixedly installed in the inner cavity of the dust collection box 205. A drainage pump 208 is fixedly installed at the bottom of the dust collection box 205. An output end of the drainage pump 208 is communicated with a drainage pipe 209. An inlet pipe 206 is fixedly installed at the top of the atomizing spray water tank 207.

[0034] By setting the dust removal mechanism 2, a suction force is generated at the input end of the dust extraction blower 201. Through the cooperation of the dust extraction pipe 202 and the corrugated pipe 203, the suction force is transmitted to the inner cavity of the concrete mixing tank 9, and the dust in the inner cavity of the concrete mixing tank 9 is adsorbed. Subsequently, the dust enters the exhaust pipe 204 through the corrugated pipe 203, the dust extraction pipe 202 and the output end of the dust extraction blower 201. At this time, the dust enters the inner cavity of the dust collection box 205 through the exhaust pipe 204, and the water source is transmitted to the atomizing spray water tank 207 through the inlet pipe 206. The atomizing spray water tank 207 atomizes and sprays the water source into the dust collection box 205 to wet the dust in the dust collection box 205. Subsequently, through the output of the drainage pump 208, the sewage in the inner cavity of the dust collection box 205 is discharged into the drainage pipe 209 to complete the cleaning of the sewage, thereby completing the dust removal work of the whole equipment, effectively avoiding the situation that when the concrete mixing tank 9 stirs the concrete inside it, a large amount of dust is generated due to the stirring, causing the dust to float in the surrounding air, which may lead to the operator inhaling these dusts and affecting the health of the operator.

[0035] Embodiment 2

[0036] As Figure 3 、 Figure 6As shown, in one embodiment, an adjustment mechanism 3 is provided on the surface of the support frame 1. The adjustment mechanism 3 includes a motor 301 and screw blocks 307. The two screw blocks 307 are both arranged on the left and right sides of the top of the support frame 1. Connecting rods 308 are fixedly installed on the inner sides of the two screw blocks 307. A dust extraction cover plate 309 is fixedly installed on the inner sides of the two connecting rods 308. One end of the corrugated pipe 203 far from the dust extraction pipe 202 communicates with the top of the dust extraction cover plate 309. Frameworks 305 are fixedly installed on the left and right sides of the top of the support frame 1. Lead screws 306 are arranged in the inner cavities of the two frameworks 305. The two screw blocks 307 are both threadedly connected to the surfaces of the two lead screws 306. The right side of the bottom of the support frame 1 is movably connected to a driving synchronous shaft 302, and the left side of the bottom of the support frame 1 is movably connected to a driven synchronous shaft 303. A synchronous transmission belt 304 is movably connected to the surfaces of the driving synchronous shaft 302 and the driven synchronous shaft 303. The bottoms of the two lead screws 306 are fixedly connected to the tops of the driving synchronous shaft 302 and the driven synchronous shaft 303. The motor 301 is fixedly installed at the bottom of the L-shaped plate 11. The output end of the motor 301 is fixedly connected to the bottom of the driving synchronous shaft 302. Thread grooves 10 are provided around the top of the concrete mixing tank 9. Fixing bolts 310 are threadedly connected to the peripheries of the top of the dust extraction cover plate 309. The bottoms of the five fixing bolts 310 are all threadedly connected to the inner cavities of the five thread grooves 10. Limit grooves 311 are provided on the front and rear sides of the inner cavities of the two frameworks 305. The front and rear sides of the two screw blocks 307 are slidably connected to the inner cavities of the four limit grooves 311. Bottom plates 5 are fixedly installed on the left and right sides of the bottom of the support frame 1. Anchor bolts 6 are threadedly connected to the front and rear sides of the tops of the two bottom plates 5.

[0037] By setting the output of the motor 301, the driving synchronous shaft 302 drives the synchronous transmission belt 304 to rotate. At this time, the driven synchronous shaft 303 rotates, and the lead screw 306 rotates. At this time, the screw block 307 drives the connecting rod 308 and the dust extraction cover plate 309 to move downward. By adjusting the height of the dust extraction cover plate 309, it is convenient to perform dust removal work on the concrete mixing tank 9 with different heights of capacity, thereby improving the overall dust removal range that the dust removal mechanism 2 can perform, facilitating the operation of the operator. By setting the thread grooves 10 and the fixing bolts 310, the dust extraction cover plate 309 can be connected to the concrete mixing tank 9, improving the sealing performance when the dust extraction cover plate 309 is connected to the concrete mixing tank 9 and preventing dust leakage during the dust suction work. By setting the limit grooves 311, the movement of the screw block 307 can be limited, preventing the screw block 307 from shifting during movement, which affects the adjustment of the height of the dust extraction cover plate 309 and restricts the overall dust suction range of the dust removal mechanism 2, affecting the use of the operator. By setting the anchor bolts 6, the overall equipment can be stabilized, preventing the overall equipment from tipping over due to accidental collisions, which affects the normal dust removal work of the equipment.

[0038] When the utility model is working: First, through the output of the motor 301, the driving synchronous shaft 302 rotates. At this time, due to the mutual cooperation between the driving synchronous shaft 302 and the synchronous transmission belt 304, the driven synchronous shaft 303 rotates synchronously. At this time, the lead screw 306 rotates synchronously due to the rotation of the driving synchronous shaft 302 and the driven synchronous shaft 303. At this time, the screw block 307 drives the connecting rod 308 and the dust extraction cover plate 309 to move downward synchronously, and makes the dust extraction cover plate 309 fit on the top of the concrete mixing tank 9. Then, rotate the fixing bolt 310 to connect the dust extraction cover plate 309 with the concrete mixing tank 9, completing the adjustment of the height of the dust extraction cover plate 309. Then, an adsorption force is generated at the input end of the dust extraction blower 201, and through the conduction of the dust extraction pipe 202 and the corrugated pipe 203, the adsorption force is conducted into the inner cavity of the concrete mixing tank 9, and the dust in the inner cavity of the concrete mixing tank 9 is adsorbed. Then, the dust enters the exhaust pipe 204 through the corrugated pipe 203, the dust extraction pipe 202 and the output end of the dust extraction blower 201. At this time, the dust enters the inner cavity of the dust collection box 205 through the exhaust pipe 204, and the water source is conducted to the atomizing spray water tank 207 through the water inlet pipe 206. The atomizing spray water tank 207 atomizes and sprays the water source into the dust collection box 205 to wet the dust in the dust collection box 205. Then, through the output of the drainage pump 208, the sewage in the inner cavity of the dust collection box 205 is discharged into the drainage pipe 209, completing the cleaning of the sewage, and thus completing the dust removal work of the whole equipment.

[0039] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
