Description

Technical Field

[0001] This utility model relates to the technical field of road coring equipment, and in particular to a road coring pollution prevention device. Background Technology

[0002] In the process of rapid urban development, highway construction is a crucial infrastructure project connecting cities. Highways are built according to national technical standards and are inspected and approved by the highway authorities. In the early stages of highway construction, core sampling of the roadbed is a very important part of highway quality inspection. When conducting quality inspection, a core sampling machine is first used to extract soil samples. The basic working principle of the core sampling machine is to use a high-speed rotating hollow drill bit to drill vertically downwards to a certain depth into the ground, and then use clamps to take out the cut sample for testing. During this process, the high-speed rotating hollow drill bit rapidly rubs against the ground, causing the drill bit's temperature to rise sharply. At this time, a large amount of water needs to be added to the outer wall of the hollow drill bit for cooling to ensure that the drill bit is not damaged. In actual operation, the water used to cool the drill bit seeps into the borehole and mixes with the soil and gravel to form sludge water. The large amount of sludge water generated at this time will be thrown out with the rapidly rotating hollow drill bit, causing large-scale pollution to the work site.

[0003] Therefore, in order to address the above problems, a road surface core sampling and pollution prevention device is proposed to solve these problems. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a pollution prevention device for road coring, which can reduce pollution caused by wastewater splashing from the coring machine.

[0005] The technical solution to the technical problem solved by this utility model is as follows: a road coring anti-pollution device, including a mudguard sleeve, a connecting structure provided on the mudguard sleeve, the connecting structure being connected to the road coring machine, a drainage pipe provided on the mudguard sleeve, and an anti-clogging structure provided on the drainage pipe.

[0006] Before operation, the road coring machine is mounted on a mudguard. The drill bit of the road coring machine works inside the mudguard. The wastewater and waste generated during operation are blocked by the mudguard to prevent splashing. The wastewater is discharged and collected through a drain pipe to reduce environmental pollution. The drain pipe is equipped with an anti-clogging structure to prevent large pieces of debris from clogging the drain pipe.

[0007] Preferably, the connection structure includes a support plate, a reinforcing rib, a connecting plate, and mounting holes. The support plate is symmetrically arranged at the lower part of the mudguard sleeve, and the reinforcing rib is arranged below the support plate. The reinforcing rib is connected to the mudguard sleeve. The connecting plate is arranged on the support plate, and the connecting plate is provided with multiple mounting holes. The connecting plate is connected to the road core sampling machine through the mounting holes.

[0008] The connecting plate has multiple mounting holes to facilitate connection with the road core sampling machine, and the support plate is equipped with reinforcing ribs to improve structural strength.

[0009] Preferably, the connecting structure also includes positioning holes, limiting screws, a first compression spring, a fixing ring, a connecting hole, and a limiting nut. Positioning holes are symmetrically arranged on both sides of the reinforcing rib on the support plate. Connecting holes corresponding to the positioning holes are provided on the support plate. Limiting screws are provided in the positioning holes and pass through the connecting holes. A limiting nut is provided on the side of the limiting screw away from the support plate. A positioning ring is provided at the end of the limiting screw close to the positioning hole. The first compression spring is sleeved on the limiting screw. The upper end of the first compression spring is connected to the connecting plate, and the lower end of the first compression spring is connected to the support plate.

[0010] By setting a limit screw, the connecting plate can be easily disassembled and installed. By setting a limit nut, the height of the connecting plate can be controlled, facilitating the adjustment of the road coring machine. By setting a first compression spring, the weight of the road coring machine is transferred to the mudguard sleeve, making the mudguard sleeve fit tightly against the ground, reducing sewage outflow, and providing support for the road coring machine, making it easy for the road coring machine to follow the drill bit downward.

[0011] As a preferred embodiment, the anti-clogging structure includes a mounting platform, support rods, a baffle, and guide holes. The mounting platform is set at the connection between the drain pipe and the mudguard sleeve. The mounting platform is located inside the mudguard sleeve. Multiple support rods are set around the mounting platform. The baffle is located inside the mudguard sleeve. Multiple guide holes are set on the baffle, and the guide holes are slidably connected to the support rods.

[0012] A baffle is installed at the drain pipe to prevent gravel and other debris from entering the drain pipe and to prevent blockage.

[0013] Preferably, the anti-clogging structure also includes a retaining ring and a second compression spring. The retaining ring is provided at the end of the support rod away from the mounting platform, and the second compression spring is provided on the support rod. The two ends of the second compression spring are respectively connected to the mounting platform and the baffle.

[0014] By setting a second compression spring, the baffle is pushed, creating a gap between the baffle and the drain pipe, allowing sewage to flow out smoothly.

[0015] Preferably, a support platform is provided at the lower end of the mudguard sleeve, and an installation groove is provided at the lower end of the support platform, with a washer placed in the installation groove.

[0016] By setting installation grooves and gaskets, the mudguard sleeve can fit the ground more closely, reducing the outflow of sewage.

[0017] Preferably, the drain pipe is located at the lower part of the mudguard sleeve, and a connector is provided on the drain pipe, which is connected to the sewage collection device.

[0018] The drain pipe is located at the bottom of the mudguard sleeve to facilitate the discharge of sewage.

[0020] Before operation, the road coring machine is installed on the mudguard sleeve. The drill bit of the road coring machine works inside the mudguard sleeve. The sewage and waste generated during operation are blocked by the mudguard sleeve to prevent splashing. The sewage is discharged and collected through the drain pipe to reduce environmental pollution. The drain pipe is equipped with an anti-clogging structure to prevent large pieces of debris from clogging the drain pipe.

[0021] By setting a limit screw, the connecting plate can be easily disassembled and installed. By setting a limit nut, the height of the connecting plate can be controlled, facilitating the adjustment of the road coring machine. By setting a first compression spring, the weight of the road coring machine is transferred to the mudguard sleeve, making the mudguard sleeve fit tightly against the ground, reducing sewage outflow, and providing support for the road coring machine, making it easy for the road coring machine to follow the drill bit downward.

Before operation, the road coring machine is mounted on the mudguard 1. The drill bit of the road coring machine operates inside the mudguard 1. Wastewater and waste generated during operation are blocked by the mudguard 1, preventing splashing. Wastewater is discharged and collected through the drain pipe 2, reducing environmental pollution. The drain pipe 2 is equipped with an anti-clogging structure to prevent large pieces of debris from clogging it.

[0033] The connecting structure includes a support plate 3, reinforcing ribs 4, a connecting plate 5, and mounting holes 6. Support plates 3 are symmetrically arranged at the lower part of the mudguard sleeve 1, and reinforcing ribs 4 are arranged below the support plates 3, connecting to the mudguard sleeve 1.
