Description

Technical Field

[0001] This application relates to the field of road construction, and more specifically, to a drainage and dredging device for road construction. Background Technology

[0002] Road construction refers to the entire process of construction involving roads, including road construction, bridge construction, and tunnel construction. During road construction, foundation pits are excavated on the road surface as needed to bury foundations or other engineering structures. Excavation of foundation pits is usually done using excavators. After excavation, due to groundwater seepage or surface water flow, some water accumulates inside the pit. Simultaneously, due to the soil composition and groundwater accumulation, some silt also forms within the pit. Both silt and accumulated water can adversely affect the stability of subsequent projects, thus requiring removal. On-site, excavators are used to remove the silt, and then pumps are used to extract the water. However, the distance between the excavator's teeth is relatively large, so some silt remains in the pit. It is necessary to first pump out the water and then manually remove the remaining silt.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] See Figure 1-Figure 4This embodiment provides a drainage and dredging device for road construction, including a base plate 1. A screening assembly 2 is arranged above the base plate 1. The screening assembly 2 includes a screening box 201, which is fixedly connected to the top of the base plate 1. A screen plate 202 is slidably connected to the inner surface of the screening box 201. The screen plate 202 is inclined and L-shaped. A spring telescopic rod 203 is fixedly connected below the screen plate 202. A support plate 204 is fixedly connected to the lower end of the spring telescopic rod 203. There are two spring telescopic rods 203 and two support plates 204. The support plate 204 is fixedly connected to the inner surface of the screening box 201. A support plate 205 is fixedly connected above the base plate 1. A rotating column 20 is rotatably connected to the front of the support plate 205. 6. An actuating block 207 is fixedly connected to the outer surface of the rotating column 206. The actuating block 207 is elliptical in shape and is eccentrically set on the rotating column 206. An actuating plate 208 is set above the actuating block 207. The actuating plate 208 is L-shaped and fixedly connected to the upper part of the sieve plate 202. The screening assembly 2 also includes a collection box 209. The collection box 209 is fixedly connected to the right side of the screening box 201. The collection box 209 and the screening box 201 are connected in communication. A collection box 210 is inserted into the front of the collection box 209. A handle is set on the collection box 210. The collection box 210 and the collection box 209 have a drawer-type structure. Four casters 3 are rotatably connected to the bottom of the base plate 1.

[0024] In practical use, the above-mentioned equipment first absorbs sewage by starting the sewage suction pump 402, causing the sewage to fall into the screening box 201. At this time, the motor 502 is started, which drives the rotating shaft 503 to rotate clockwise. The rotation of the rotating shaft 503 drives the worm thread 505 to rotate clockwise, which drives the worm wheel 506 to rotate counterclockwise. The rotation of the worm wheel 506 drives the rotating column 206 to rotate counterclockwise, which drives the actuating block 207 to rotate counterclockwise. The actuating block 207 continuously pushes the actuating plate 208 upward, which pulls the screen plate 202 upward, causing the spring telescopic rod 203 to stretch. When the actuating block 207 leaves the actuating plate 208, the spring telescopic rod 203 will elastically return to its original position and pull the screen plate 202 downward. The screen plate 202 will vibrate under the action of elasticity and slide up and down in the screening box 201, thereby screening the impurities in the sewage.

[0025] Example 2

[0026] See Figure 1-Figure 4Based on Embodiment 1, a sewage suction assembly 4 is provided above the base plate 1. The sewage suction assembly 4 includes a lifting chamber 401, with a discharge port on the right side of the lifting chamber 401. The lifting chamber 401 is fixedly connected to the top of the base plate 1. A sewage suction pump 402 is fixedly installed on the left side of the lifting chamber 401. The sewage suction pump 402 is used to absorb sewage and transport it into the lifting chamber 401. A sewage suction pipe 403 is fixedly installed on the left side of the sewage suction pump 402, and a sewage suction head is provided on the sewage suction pipe 403. A drive assembly 5 is provided above the lifting chamber 401. The drive assembly 5 includes a support base 501, which is fixedly connected to the top of the lifting chamber 401. A motor 502 is fixedly connected to the right side of the support base 501. 2. The output end faces downward. The output end of the motor 502 is fixedly connected to the rotating shaft 503 through a coupling. The rotating shaft 503 passes through and is rotatably connected to the top of the lifting chamber 401. The outer surface of the rotating shaft 503 is fixedly connected to the auger blade 504. The auger blade 504 is disposed on the inner surface of the lifting chamber 401. The drive assembly 5 also includes a worm thread 505. The worm thread 505 is disposed above the lifting chamber 401 and on the outer surface of the rotating shaft 503. A worm wheel 506 is meshed on the right side of the worm thread 505. The worm wheel 506 is fixedly connected to the outer surface of the rotating column 206. The outer surface of the rotating column 206 is provided with a shaft bracket for supporting the rotation of the rotating column 206.

[0027] When the above-mentioned equipment is in use, the sewage suction pump 402 will absorb sewage through the sewage suction pipe 403 and transport it into the lifting chamber 401. At this time, as the motor 502 drives the rotating shaft 503 to rotate, the motor 502 will also drive the auger blades 504 to rotate, thereby transporting the sewage in the lifting chamber 401 to the top. After the sewage is transported to the top of the inner surface of the lifting chamber 401, it will eventually flow out from the discharge port on the right side of the lifting chamber 401 and fall into the screening box 201, thus starting the screening.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
