[0045] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0046] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0047] See also Figure 1-7 This embodiment provides a road survey and coring device, which mainly includes: a base plate 100, a steering assembly 200, a lifting assembly 300 and a coring assembly 400.

[0048] The base plate 100 is the main structure for movement and support of the road survey and coring device of this embodiment. Figure 1 , Figure 2 As shown in , the main body of the bottom plate 100 is a roughly rectangular flat plate. Four rollers are arranged on the lower surface of the bottom plate 100 for movement. A push rod 110 is arranged near the left end of the upper surface of the bottom plate 100 for easy pushing, a steering assembly 200 is fixedly installed at the middle of the upper surface, and a control box 500 is installed between the push rod 110 and the steering assembly 200 on the upper surface. In addition, a rectangular core unloading port 103 penetrating the bottom plate 100 is provided on the left side of the fixed connection position between the bottom plate 100 and the steering assembly 200, serving as a discharge port for removing samples; a circular core removal port 101 penetrating the bottom plate 100 is provided on the right side of the fixed connection position between the bottom plate 100 and the steering assembly 200, serving as a downward working port of the core removal assembly 400.

[0049] like Figure 1-4As shown in the figure, the steering assembly 200 mainly includes a cylindrical rotating drum 210, etc., which is used to realize the conversion of the corer 420 of the core removal assembly 400 between the core removal port 101 and the core removal port 103. Among them, a clamping ring 230 is set at the bottom of the steering assembly 200, and the clamping ring 230 is set horizontally and fixedly connected to the middle of the upper surface of the bottom plate 100. The rotating drum 210 is set vertically, and its lower end is clamped in the clamping ring 230, and can rotate relative to the clamping ring 230 and move up and down. At the same time, Figure 1-4 As shown in the figure, the steering assembly 200 is relatively fixed in the horizontal direction with the coring assembly 400 through the lifting assembly 300. Therefore, the core remover 420 below the coring assembly 400 will rotate with the rotation of the drum 210 in the retaining ring 230. Because the distance from the center of the core unloading port 103 to the drum 210 is equal to the distance from the center of the core taking port 101 to the drum 210 in this embodiment, the conversion between the core taking port 101 and the core unloading port 103 is achieved.

[0050] like Figure 1-5 As shown in , the lifting assembly 300 is mainly composed of a rectangular parallelepiped slide bar 310 and a rectangular plate-shaped mounting plate 340, etc., which are used to realize the up and down lifting of the corer 420 in the core removal assembly 400 to meet the height requirements of coring at different depths and unloading the core. The slide bar 310 in the lifting assembly 300 is vertically arranged and slidably embedded in the rotating drum 210, and can move up and down relative to the rotating drum 210, but the shape of the hollow part of the rotating drum 210 is adapted to the rectangular parallelepiped slide bar 310, which is also square, so the two cannot rotate relative to each other. In addition, a vertical screw rod 320 is embedded inside the slide bar 310, and the screw rod 320 is threadedly connected to the slide bar 310. The upper end of the screw rod 320 is buried in the slide bar 310, and the lower end extends out of the lower surface of the slide bar 310 and is fixedly connected to the output end of the second motor 330, and is controlled to rotate by the second motor 330, and the second motor 330 is fixedly installed at the bottom of the rotating drum 210. Therefore, when the second motor 330 is started, the screw rod 320 rotates and drives the slide bar 310 to move up and down in the drum 210. At the same time, the upper end of the slide bar 310 is fixedly embedded in the groove 341 on the lower surface of the mounting plate 340, so that the mounting plate 340 can also move up and down. Moreover, the mounting plate 340 is arranged horizontally, and the side away from the drum 210 is also penetrated and fixedly connected with the coring assembly 400, so the coring assembly 400 is also controlled by the second motor 330 to move up and down, so as to meet the height requirements of coring and unloading at different depths. In addition, in this embodiment, a scale is also arranged on the side of the slide bar 310, so that the operator can judge the depth of the corer 420 according to the scale, making the operation more accurate.

[0051] The coring assembly 400 is used to drill on the ground at a designated location to obtain geological samples. As shown in 1-5, the coring assembly 400 mainly includes a transmission rod 410, a corer 420, and a first motor 430. Among them, the transmission rod 410 is fixedly connected to the mounting plate 340, and can move up and down and rotate with the mounting plate 340. When it rotates to the rightmost end, the lower part faces the coring port 101, and the coring operation can be performed; when it rotates to the leftmost end, the lower part faces the core unloading port 103, and the core unloading operation can be performed. The upper end of the transmission rod 410 is located on the upper surface of the mounting plate 340, and is fixedly connected to the first motor 430. The output end of the first motor 430 is fixedly connected to the transmission shaft inside the transmission rod 410. The transmission shaft runs through the transmission rod 410, and its lower end is connected to the drill bit in the corer 420 to control its rotation. The corer 420 is a direct coring device and is fixedly connected to the lower end of the transmission rod 410. Therefore, like the transmission rod 410, it can rotate between the coring port 101 and the core unloading port 103, and can also move up and down to meet the height requirements of different operations.

[0052] A specific implementation of this embodiment is as follows: first, the road survey coring device of this embodiment is moved to the location where coring is required, and the steering assembly 200 is rotated to the position where the coring device 420 is facing the coring port 101, such as Figure 3 As shown. Next, start the control box 500, the second motor 330 drives the lifting assembly 300 to control the coring assembly 400 to move downward, and the first motor 430 drives the coring device to drill and coring. After the coring operation is completed and the roots are cut off, operate the control box 500 again, the second motor 330 drives the lifting assembly 300 to control the coring assembly 400 to move upward until the coring device 420 passes through the top of the coring port 101. Then, the steering assembly 200 rotates to the position where the coring device 420 is facing the core unloading port 103, as shown. Figure 4 As shown, the control box 500 is started again, and the second motor 330 drives the lifting assembly 300. At this time, the coring assembly 400 is controlled to move up and down, and the first motor 430 drives the core drill bit to rotate. These two actions together loosen the sample in the corer, which can be easily removed and fall into the core unloading port 103 for convenient collection, so that the coring device of this embodiment can easily unload the sample.

[0053] In this embodiment, the road survey and coring device is provided with a steering assembly 200, which cooperates with the lifting assembly 300 to control the corer 420 on the coring assembly 400 to move between different positions and heights. After coring, the sample can be quickly unloaded, and the sample unloading process is convenient and fast. The samples fall into the core unloading port 103 in a concentrated manner and are easier to collect, thereby realizing a convenient and efficient sample unloading and collection process. The problem in the prior art that the samples of the coring device are easily stuck in the corer and sometimes need to be knocked with hard objects, which is inconvenient to unload and difficult to collect, resulting in low work efficiency is solved.

[0054] Preferably, in this embodiment, in order to reduce the impact of rotating splashing of sand and stones during the coring and unloading process on the work, the steering assembly is also provided with a protective cylinder 220. Specifically, a connecting rod 240 is fixedly installed at the upper and lower positions on the outer side of the rotating cylinder 210 facing the coring assembly 400, and the rotating cylinder 210 and the connecting rod 240 are bolted to facilitate disassembly and replacement. Both connecting rods 240 are arranged horizontally, and in the same vertical plane, the other ends of the two connecting rods 240 are fixedly connected to one side of the outer surface of the protective cylinder 220. Therefore, when the rotating cylinder 210 rotates, the protective cylinder 220 will also rotate around its rotating axis. At the same time, the position of the protective cylinder 220 is set at a position directly opposite to the coring assembly 400 that will pass through during the lifting process. During the coring operation, the protective tube 220 blocks the coring port 101 to prevent sand and stones from splashing upward into the equipment; during the core unloading operation, after the lifting assembly 300 adjusts the height, the corer 420 is located inside the protective tube 220 and reciprocates between the inside of the core unloading port 103, and the protective tube 220 blocks the corer 420 to prevent sand and stones from splashing around into the equipment or injuring people. In this embodiment, by providing the protective tube 220, it is avoided that sand and stones splash and damage the machine or injure people, thereby improving the safety of the road survey coring device and reducing the probability of failure. At the same time, the corer 420 in this embodiment can be stored in the protective tube 220 for protection when not in operation, which can further enhance the maintenance of the equipment and improve the service life of the road survey coring device.

[0055] Preferably, in this embodiment, the drum 210 and the clamping ring 230 below can rotate relative to each other, which makes it unstable during operation. When the friction between the two is insufficient, the drum 210 is prone to rotation deviation when it is not necessary to rotate, such as when coring and unloading, which affects the use of the device. Figure 6 , Figure 7As shown in , a block 212 and a slot 231 are further provided at the bottom of the drum 210 and the inner side of the snap ring 230, respectively. Specifically, two rectangular blocks 212 are symmetrically arranged on both sides of the bottom of the side of the drum 210, and two slots 231 of matching shapes are symmetrically arranged on the top of the inner side wall of the snap ring 230. When coring, the two blocks 212 face the two slots 231 and snap in them, preventing the steering assembly 200 from rotating at this time, so that it can remain fixed; when unloading the core, the two blocks 212 rotate 180° and face the two slots 231 and snap in them, preventing the steering assembly 200 from rotating at this time, so that it can remain fixed; when it needs to move, the drum 210 moves up to disengage the two blocks 212 from the two slots 231, so that it can be rotated and the position can be changed. In this embodiment, by providing two clamping blocks 212 and two clamping slots 231, the steering assembly 200 can remain stable during coring and unloading, thereby improving the working stability and practicality of the road survey coring device.
