Description

Technical Field

[0001] The utility model relates to the technical field of road coring, in particular to a multifunctional road material coring device. Background Technique

[0002] The road material coring device is an important road maintenance and detection equipment. It can drill core samples from road materials to understand the structure, materials and performance of the road. The working principle of the road material coring device is mainly based on drilling technology. By driving the coring barrel to rotate at high speed and applying downward pressure, core samples are drilled from the road materials, which are widely used in road maintenance and detection everywhere. For example, in road projects such as highways and urban roads, core samples are drilled to evaluate the performance and quality of road materials, providing a basis for road repair and renovation.

[0003] During the use of the existing road coring device, a large amount of dust will be generated. In order to prevent dust from polluting the surrounding environment, corresponding structures are generally set up to prevent the spread of dust. However, the road environment is relatively complex, some roads are rough and uneven, and some dust is likely to spill from the gap between the dust-proof structure and the ground, so that the dust-proof effect is still not good enough and the function is relatively single. Content of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the above technical defects.

[0005] Therefore, an object of the present utility model is to provide a multifunctional road material coring device to solve the problems mentioned in the background technique and overcome the deficiencies in the prior art.

A bracket is fixedly connected to the top of the moving seat, and a cylinder is fixedly installed on the top of the bracket. One end of the output shaft of the cylinder is fixedly installed with a lifting seat. A sampling structure is arranged at the bottom of the lifting seat. A fixed protective cylinder is fixedly installed on the surface of the lifting seat. A sliding protective cylinder is arranged at the bottom of the fixed protective cylinder. A plurality of first springs are arranged on one side of the sliding protective cylinder. A connecting plate is fixedly connected to the surface of the sliding protective cylinder. A rubber plate is fixedly installed on the surface of the connecting plate. A dust-proof cloth is fixedly installed at the bottom of the connecting plate. A plurality of counterweights are fixedly installed on the surface of the dust-proof cloth. A receiving groove is opened at the bottom of the sliding protective cylinder. A plurality of blocking blocks are slidably connected inside the receiving groove. The technical effect achieved by adopting the above solution is that: through the operation of the cylinder to drive the lifting seat to descend, first the dust-proof cloth contacts the ground first, and then through a plurality of counterweights, the dust-proof cloth can contact the ground according to the different terrain heights, so that the dust-proof cloth initially seals the gap between the sliding protective cylinder and the ground. Then the rubber plate contacts the ground and deforms accordingly according to the shape of the ground. Finally, a plurality of blocking blocks contact the ground and slide into the receiving groove, so as to closely adhere to the ground according to the shape of the ground, which can make the sealing effect better when coring the road and prevent the overflow of dust.

[0007] Preferably, from any of the above solutions, the sampling structure includes a motor. The motor is fixedly installed inside the lifting seat.

One end of the connecting frame is fixedly connected with a fixed cylinder. A through hole adapted to the sampling cylinder is opened in the middle of the fixed cylinder. The technical effect achieved by adopting the above solution is that: through the two connecting frames, the fixed cylinder can be fixedly installed on the surface of the sampling cylinder, so as to cooperate with the sliding protective cylinder to seal and protect the periphery of the sampling cylinder, so that dust can be effectively prevented from overflowing during the coring operation.

[0009] Preferably, according to any of the above solutions, a groove is provided at the top of the sliding protection cylinder, and a plurality of first springs are fixedly installed on the inner wall of the groove. One end of each of the plurality of first springs is connected to the bottom of the fixed cylinder. The technical effect achieved by adopting the above solution is that after the sliding protection cylinder descends and contacts the ground, the sliding protection cylinder then performs a rising operation while applying pressure to the first springs.
