Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a sampling device for geological surveying. Background Technology

[0002] Geological mapping is the process of drawing geological and topographic maps by measuring, observing and recording the topography, geological features and underground geological structures of the Earth's surface. In order to understand the structure of underground soil, it is necessary to use sampling equipment to drill holes and extract the underground soil to facilitate understanding of the soil structure.

[0003] There are still some problems in the use of existing geological surveying sampling equipment. During use, due to the unevenness of the outdoor ground, it is not convenient to adjust the equipment to drill horizontally downwards. In addition, the drilling force may be tilted during use, which can also easily lead to borehole tilting. Therefore, those skilled in the art provide a geological surveying sampling equipment to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling device for geological mapping. The device supports the base through a support structure. During the support process, the rotatability of the sphere and the ball seat facilitates support on uneven ground. Furthermore, the first and second drive structures ensure that the displacement is the same as the descent force during drilling, preventing tilting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for geological surveying, comprising a base, six supporting structures arranged in a rectangular pattern on the lower end face of the base, a lifting plate on the upper end of the base, a top seat on the upper end of the lifting plate, a top cover on the upper end face of the top seat, and a first driving structure fixedly connected to one side wall of the lifting plate;

[0006] The support structure includes a first hydraulic cylinder, with a ball fixedly connected to the output end of the first hydraulic cylinder, and a ball seat rotatably sleeved on the lower part of the outer side wall of the ball.

[0007] The first drive structure includes a frame, a second servo motor is fixedly connected to the rear of the center of one side wall of the frame, and a first synchronous wheel is arranged front and back inside the frame near one side. The output end of the second servo motor passes through the frame and extends into the frame, and its end is fixedly connected to the end of the rear first synchronous wheel. One end of each of the two first synchronous wheels passes through one side wall of the lifting plate and extends into the lifting plate, and each end is fixedly connected to a first lead screw. A slider is threaded onto the outer wall of the two first lead screws, and a first synchronous belt is fitted onto the outer wall of the two first synchronous wheels.

[0008] Through the above technical solution, by controlling the extension and retraction of the six first hydraulic cylinders, the bottom of the six ball seats are made to fit against the ground to support the base, which facilitates the horizontal support of the base on uneven ground. By controlling the start of the second servo motor, the second servo motor drives the first synchronous pulley at the rear to rotate, and then drives the first synchronous pulley at the front to rotate synchronously through the first synchronous belt. The two first lead screws rotate synchronously, so that the slider moves smoothly to one side.

[0009] Furthermore, the top seat is provided with a second drive structure, which includes a third servo motor. The third servo motor is fixedly connected to a diagonal position at the rear of one side of the top seat. A second synchronous wheel is rotatably connected to each of the four diagonal positions of the lower inner wall of the top seat. The output end of the third servo motor is fixedly connected to one of the second synchronous wheels. A second synchronous belt is sleeved on the outer side of the four second synchronous wheels. The lower ends of the four second synchronous wheels all pass through the top seat to the lower end of the top seat, and a second lead screw is fixedly connected to each end. The four second lead screws all pass through the upper surface of the lifting plate to the lower end of the lifting plate, and their ends are rotatably connected to the four diagonal positions of the upper surface of the base.

[0010] The above technical solution controls the start of the third servo motor, which drives the second synchronous pulley at the rear of one side to rotate. The second synchronous belt then drives the other three second synchronous pulleys to rotate synchronously, thereby causing the four second lead screws to rotate synchronously and the lifting plate to move downward along the four second lead screws.

[0011] Furthermore, the slider is provided with a sampling structure, which includes a first servo motor. The first servo motor is fixedly connected to the lower inner wall of the slider. The output end of the first servo motor is fixedly connected to a first reducer. The output end of the first reducer passes through the lower inner wall of the slider and extends to the lower end of the slider. A sampling barrel is fixedly connected to the end of the first reducer. A groove is provided on the lower end face of the sampling barrel. Multiple base plates are arranged in a circle on the inner wall of the groove. Multiple rotating plates are rotatably connected to the lower ends of the multiple base plates. A third hydraulic cylinder is rotatably connected to the outer side of the center of the lower end face of the multiple base plates. The output ends of the multiple third hydraulic cylinders are respectively rotatably connected to the upper surface of the multiple rotating plates. A drilling machine is provided on the lower end face of the multiple rotating plates.

[0012] The above technical solution controls the start of the first servo motor, which drives the first reducer to rotate. The output of the first reducer drives the sampling bucket to rotate, and then controls multiple drilling rigs to start drilling while rotating downwards.

[0013] Furthermore, a second hydraulic cylinder is fixedly connected to the upper inner wall of the groove between the plurality of substrates, and a shrink plate is fixedly connected to the output of the plurality of second hydraulic cylinders;

[0014] The above technical solution facilitates the upward movement of the shrink plate after the multiple second hydraulic cylinders retract.

[0015] Furthermore, four guide rods are arranged in a rectangular pattern at the center of the upper surface of the base. The upper ends of the four guide rods all pass through the lifting plate and extend to the upper end of the lifting plate, and the ends are all fixedly connected to the lower surface of the top seat.

[0016] The above technical solution facilitates the guidance of the lifting platform.

[0017] Furthermore, a battery module is provided inside the top mount;

[0018] The above technical solution facilitates the provision of electrical power to the equipment.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the sampling equipment for geological surveying transports the equipment to the location where sampling is required, places the equipment on the ground, and controls the extension and retraction of the six first hydraulic cylinders to make the bottom of the six ball seats fit against the ground, thus supporting the base and facilitating horizontal support of the base on uneven ground.

[0021] 2. In this utility model, by controlling the start of the second servo motor, the second servo motor drives the first synchronous wheel at the rear to rotate, and then drives the first synchronous wheel at the front to rotate synchronously through the first synchronous belt. The two first lead screws rotate synchronously, so that the slider moves smoothly to one side. Then, by controlling the start of the third servo motor, the third servo motor drives the second synchronous wheel at the rear on one side to rotate, and then drives the other three second synchronous wheels to rotate synchronously through the second synchronous belt. This causes the four second lead screws to rotate synchronously, so that the lifting plate moves downward along the four second lead screws and four guide rods. The setting of the first drive structure and the second drive structure enables the sampling structure to move smoothly to both sides and up and down, improving the drilling accuracy.

[0022] 3. In this utility model, when the sampling bucket enters the ground, the third servo motor stops, and then controls multiple second hydraulic cylinders to retract. The multiple second hydraulic cylinders drive multiple retraction plates to move into the groove. Then, the multiple third hydraulic cylinders extend, and the multiple third hydraulic cylinders push multiple rotating plates to rotate, wrapping the soil around the lower end of the sampling bucket to prevent the broken soil inside from falling directly.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-6 An embodiment of this utility model is provided: a sampling device for geological mapping, including a base 1, six supporting structures 2 arranged in a rectangle on the lower end face of the base 1, a lifting plate 4 on the upper end of the base 1, a top seat 6 on the upper end of the lifting plate 4, a top cover 5 on the upper end face of the top seat 6, and a first driving structure 7 fixedly connected to one side wall of the lifting plate 4.

[0033] The support structure 2 includes a first hydraulic cylinder 201. A ball 202 is fixedly connected to the output end of the first hydraulic cylinder 201. A ball seat 203 is rotatably sleeved on the lower part of the outer side wall of the ball 202. By controlling the extension and retraction of the six first hydraulic cylinders 201, the bottom of the six ball seats 203 are made to fit against the ground to support the base 1, which facilitates the horizontal support of the base 1 on uneven ground.

[0034] The first drive structure 7 includes a frame 706. A second servo motor 701 is fixedly connected to the rear center of one side wall of the frame 706. First synchronous pulleys 702 are arranged front and back inside the frame 706 on one side. The output end of the second servo motor 701 passes through the frame 706 and extends into the frame 706, and its end is fixedly connected to the end of the rear first synchronous pulley 702. One end of each of the two first synchronous pulleys 702 passes through one side wall of the lifting plate 4 and extends into the lifting plate 4, and each end is fixedly connected to a first lead screw 704. A slider 705 is threaded onto the outer wall of the two first lead screws 704. A first synchronous belt 703 is sleeved on the outer wall of the two first synchronous pulleys 702. By controlling the second servo motor 701 to start, the second servo motor 701 drives the rear first synchronous pulley 702 to rotate, and then drives the front first synchronous pulley 702 to rotate synchronously through the first synchronous belt 703. The two first lead screws 704 rotate synchronously, so that the slider 705 moves smoothly to one side.

[0035] like Figure 1 , 3 As shown in Figure 4, the top seat 6 is equipped with a second drive structure 9, which includes a third servo motor 901. The third servo motor 901 is fixedly connected to a diagonally opposite rear side of the top seat 6. Four second synchronous pulleys 902 are rotatably connected to the four diagonally opposite corners of the lower inner wall of the top seat 6. The output end of the third servo motor 901 is fixedly connected to one of the second synchronous pulleys 902. A second synchronous belt 903 is fitted around the four second synchronous pulleys 902. The lower ends of the four second synchronous pulleys 902 all penetrate the top seat 6 and extend to the lower end of the top seat 6. Each end is fixedly connected to a second lead screw 904. All four second lead screws 904 pass through the upper end of the lifting plate 4 and extend to the lower end of the lifting plate 4. Their ends are rotatably connected to the four opposite corners of the upper end of the base 1. The third servo motor 901 is started, and the third servo motor 901 drives the second synchronous wheel 902 at the rear of one side to rotate. Then, through the second synchronous belt 903, it drives the other three second synchronous wheels 902 to rotate synchronously, thereby causing the four second lead screws 904 to rotate synchronously, so that the lifting plate 4 moves downward along the four second lead screws 904.

[0036] like Figure 1 , 4As shown in Figure 5, a sampling structure 3 is provided inside the slider 705. The sampling structure 3 includes a first servo motor 301, which is fixedly connected to the lower inner wall of the slider 705. A first reducer 303 is fixedly connected to the output end of the first servo motor 301. The output end of the first reducer 303 passes through the lower inner wall of the slider 705 and extends to the lower end of the slider 705. A sampling barrel 304 is fixedly connected to the end of the first reducer 303. A groove 305 is provided on the lower end face of the sampling barrel 304. Multiple substrates 306 are arranged in a circular pattern on the upper inner wall of the groove 305. Multiple rotating plates 307 are rotatably connected to the lower end of each plate 306. A third hydraulic cylinder 310 is rotatably connected to the outer side of the center of the lower end face of each plate 306. The output ends of the multiple third hydraulic cylinders 310 are rotatably connected to the upper end face of each rotating plate 307. A drill 308 is provided on the lower end face of each rotating plate 307. The first servo motor 301 is started, and the first servo motor 301 drives the first reducer 303 to rotate. The output end of the first reducer 303 drives the sampling barrel 304 to rotate. Then, the multiple drill 308 are started to drill holes while rotating downwards.

[0037] A second hydraulic cylinder 309 is fixedly connected to the upper inner wall of the groove 305 between multiple substrates 306. The output of the multiple second hydraulic cylinders 309 is fixedly connected to a shrink plate 302, so that after the multiple second hydraulic cylinders 309 shrink, they can drive the shrink plate 302 to move upward.

[0038] Four guide rods 8 are arranged in a rectangle at the center of the upper surface of the base 1. The upper ends of the four guide rods 8 all pass through the lifting plate 4 and extend to the upper end of the lifting plate 4. The ends of the guide rods 8 are all fixedly connected to the lower surface of the top seat 6 to facilitate the guidance of the lifting plate 4. The top seat 6 is equipped with a battery module 10 to provide power to the equipment.

[0039] Working principle: When in use, the equipment is transported to the location where sampling is required. The equipment is placed on the ground, and the extension and retraction of the six first hydraulic cylinders 201 are controlled to make the bottom of the six ball seats 203 fit against the ground, supporting the base 1. This makes it easy to horizontally support the base 1 on uneven ground.

[0040] In use, by controlling the second servo motor 701 to start, the second servo motor 701 drives the first synchronous pulley 702 at the rear to rotate, and then drives the first synchronous pulley 702 at the front to rotate synchronously through the first synchronous belt 703. The two first lead screws 704 rotate synchronously, so that the slider 705 moves smoothly to one side. Then, by controlling the third servo motor 901 to start, the third servo motor 901 drives the second synchronous pulley 902 at the rear on one side to rotate, and then drives the other three second synchronous pulleys 902 to rotate synchronously through the second synchronous belt 903. This causes the four second lead screws 904 to rotate synchronously, so that the lifting plate 4 moves downward along the four second lead screws 904 and the four guide rods 8. The setting of the first drive structure 7 and the second drive structure 9 enables the sampling structure 3 to move smoothly to both sides and up and down, improving the drilling accuracy.

[0041] Then, the first servo motor 301 is started, which drives the first reducer 303 to rotate. The output of the first reducer 303 drives the sampling bucket 304 to rotate. Then, multiple drills 308 are started to drill holes while rotating downwards. When the sampling bucket 304 enters the ground, the third servo motor 901 stops. Then, multiple second hydraulic cylinders 309 are retracted, which drives multiple retraction plates 302 to move into the groove 305. Then, multiple third hydraulic cylinders 310 are extended, which push multiple rotating plates 307 to rotate, covering the lower end of the sampling bucket 304 with soil to prevent the soil fragments inside from falling directly.

[0042] Then, control the third servo motor 901 to start in reverse. The third servo motor 901 drives the second synchronous wheel 902 to rotate in reverse, so that the lifting plate 4 moves upward along the four second lead screws 904 and the four guide rods 8 to remove the soil. After removal, place the collection cylinder on one side of the sampling barrel 304. Control the second servo motor 701 to start in reverse, so that the sampling barrel 304 moves onto the collection barrel. Then, control the multiple third hydraulic cylinders 310 to retract, so that the multiple rotating plates 307 are pulled outward, so that the multiple rotating plates 307 are perpendicular to the ground. The soil inside the sampling barrel 304 falls into the collection cylinder. Then, control the multiple second hydraulic cylinders 309 to extend, so that the multiple retracting plates 302 are pushed downward to support the multiple rotating plates 307 for easy sampling.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
