The bottom of the connecting rod c241 has a T-shaped positioning groove 242. The positioning block 244 matches the shape of the positioning groove 242 and can slide within the groove. This structural design enables the positioning and installation of the drill bit 247. The bottom of the positioning block 244 is fixedly connected to the connecting rod d243. The connecting plates 245 are fixed to the upper sides of the connecting rod d243. The connecting plates 245 have threaded holes, and the positioning block 244 can be fixed to the connecting rod c241 by hand-tightening the screw 246, facilitating the quick and easy disassembly and replacement of the drill bit 247. The head 247 is made of cemented carbide and features a specially treated cutting edge, enabling it to efficiently drill into roadbed materials of varying hardness, ensuring both the quality and efficiency of sample collection. The collection and detection mechanism 6 consists of a support plate b61, a collection module 62, and a detection component 63. The right side of the support plate b61 is welded to the left side of the sampling component 23. Made of high-strength aluminum alloy, it possesses excellent strength and corrosion resistance. The collection module 62 is mounted on the top of the support plate b61. A partition 621 is located above the inside of the collection module 62, dividing the internal space into different functional areas. A fan 622 is mounted on the partition 621. The fan 622 employs a centrifugal design, generating strong suction. The drilled sample is then transferred through an air exchange port 623. The sample collected by component 24 is drawn into the collection module 62. The bottom of the air vent 623 is connected to the connecting rod b235 to ensure smooth sample transport. Detection components 63 are installed on both sides of the collection module 62. Each detection component 63 consists of a connecting rod g631 and a detector 632. The top of the connecting rod g631 is connected to the collection module 62, and the bottom of the detector 632 is fixed to it. The detector 632 is installed on the top of the support plate 1 and integrates multiple high-precision sensors to quickly and accurately detect parameters such as sample compaction and density, and transmits the data to the chassis 9 for analysis and processing. In addition, the support plate 1 serves as the basic load-bearing component of the entire device, and walking components 7 are installed at the four corners of its bottom. The walking components 7 consist of... The device consists of a connecting plate 71, an axle 72, and wheels 73. The top of the connecting plate 71 is welded to the bottom of the support plate 1. Two connecting plates 71 are set at each corner, and the axle 72 is installed between the two connecting plates 71 via bearings. The wheels 73 are externally connected to the axle 72. The wheels 73 are made of high-elasticity rubber with internal reinforcing ribs, providing good shock absorption and wear resistance, facilitating movement of the device on roadbeds with different conditions. A handle 8 is installed on the top rear side of the support plate 1, with a non-slip rubber layer on its surface for easy pushing by the operator. A metal housing 9 is installed in the middle of the top rear side, housing control circuits and data processing modules for intelligent control and data storage analysis of the entire testing process.
[0030] Working Principle: When using the device for testing roadbed compaction, the device is moved to the testing position via the traveling assembly 7, which is fixedly connected to the four corners of the bottom of the support plate 1. In the traveling assembly 7, the top of the connecting plate 71 is connected to the bottom of the support plate 1, and the axle 72 between the two connecting plates 71 supports the wheel 73, facilitating the movement of the device. After reaching the testing position, the support mechanism 3 takes effect. The bottom of the support rod b31 is fixed to the top of the support plate 1, and the connecting rod e311 slides inside the end of the support rod b31. In conjunction with the sliding grooves a321 and b322 of the support assembly 32, the position of the support assembly 32 can be adjusted to stabilize the device. The sampling assembly 23, the lifting assembly 22 on the top of the sampling assembly 23, and the hydraulic cylinder 21 on the top of the lifting assembly 22 are ready. During sampling, the driving end of the hydraulic cylinder 21 drives the pad a211 to move, thereby controlling the lifting assembly 22. The four pads b221 inside the lifting assembly 22 and the support rod a222 can ensure the stability of the device. To ensure stability and precision during the lifting process, the material extraction assembly 23 is raised and lowered. The motor 232 in the material extraction assembly 23 drives the bevel gear 234 to rotate via connecting rod a233. The meshing bevel gear 234 transmits power to connecting rod b235, causing the drilling assembly 24 to rotate. The bottom positioning groove 242 of the connecting rod c241 of the drilling assembly 24 engages with the positioning block 244. The drill bit 247 can be quickly fixed to the connecting rod c241 via the connecting plate 245 and the hand screw 246. The system enables quick installation and replacement of drill bit 247. During drilling, the spray assembly 4 starts working. Water tank 41 is fixed to the bottom of support plate 1. The rigid water pipe 42 on the back of water tank 41 delivers water to nozzle 43. The holes inside nozzle 43 spray water to reduce dust and cool the drilling area. At the same time, the dust collector 51 of dust removal assembly 5 collects dust and debris generated during drilling through suction nozzle 53 connected by connecting rod f52, keeping the working environment clean.
[0031] The bottom positioning groove 242 of the connecting rod c241 of the drilling assembly 24 cooperates with the positioning block 244. The drill bit 247 can be quickly fixed on the connecting rod c241 through the connecting plate 245 and the hand screw 246, realizing the quick installation and replacement of the drill bit 247. The drilled sample is processed in the collection and detection mechanism 6. The support plate b61 is fixed on the left side of the sampling assembly 23. The partition 621 in the collection module 62 divides the space. The fan 622 sucks the sample into the collection module 62 through the air exchange port 623 and the internal structure connected to the connecting rod b235. The detection components 63 on both sides of the collection module 62 use the detector 632 connected to the connecting rod g631 to detect the compaction of the sample. After the detection is completed, the handle 8 on the top rear side of the support plate 1 makes it convenient for the operator to move the device. The chassis 9 in the middle of the top rear side of the support plate 1 can store and process the detection data.
