Technical Field
[0001] This utility model relates to the field of rare earth exploration technology, specifically a weathered crust type rare earth ore field exploration and sampling device. Background Technology
[0002] In the fields of new energy materials and strategic mineral resource development, weathered crust rare earth deposits are an important type of rare earth resource in my country. Their exploration work is of key significance for ensuring the supply of rare earth resources and promoting the development of high-tech industries. When sampling, it is necessary to carve grooves on the profile, take out the sand and soil in the grooves, and take one sample per meter.
[0003] Regarding the above situation, the inventors have discovered the following problems: weathered crust type rare earth deposits are mostly found in areas with complex terrain such as hills and mountains, and the ore layers are distributed on mountain slopes or steep slopes. Traditional exploration relies on manual climbing of slopes for sampling. Manual climbing of slopes is prone to landslides or falls, posing significant safety hazards. It is difficult to quickly complete large-area sampling work. Furthermore, the size and depth of the manual cutting grooves are difficult to ensure consistency, affecting the accuracy of the sampling data.
[0004] Therefore, it is necessary to improve existing sampling tools. Summary of the Invention
[0005] Therefore, this utility model proposes a field exploration and sampling device for weathered crust type rare earth minerals, which can automatically sample mineral bodies on sloping slopes instead of manually, avoiding the risk of landslides and falls that are easy to occur during manual sampling. Moreover, the sampling is standardized, fast, and efficient, thus overcoming the shortcomings of the existing technology.
[0006] This utility model proposes a weathered crust-type rare earth ore field exploration and sampling device, which has a support mechanism, a storage mechanism, an adjustment mechanism, and a sampling mechanism. The support mechanism includes a base and a second electric telescopic rod mounted on the base. The second electric telescopic rod is driven to extend and retract by a first servo motor. The adjustment mechanism has a housing fixed to the end of the second motor telescopic rod, and a third servo motor is installed inside the housing. A plate is mounted on the shaft of the third servo motor and rotates 360 degrees. A movable frame is mounted on the plate via a linear motor, and a sampling mechanism is mounted on the movable frame. The sampling mechanism is driven by its second servo motor to swing and adjust its angle. The sampling mechanism has a transmission box, with output shafts at both ends connected to a drill barrel and a dust collection disc, driving the drill barrel and dust collection disc to take samples. The dust collection disc contains a scraper and has a pipe connected to a vacuum cleaner mounted on the top of the transmission box.
[0007] Furthermore, a dual-axis motor is fixedly installed inside the transmission box. The two output shafts of the dual-axis motor are respectively connected to the rotating ends of the scraper and the conductive slip ring. The conductive slip ring is then connected to the rotating shaft of the drill barrel for transmission.
[0008] The transmission box contains a dual-axis motor. The shafts at both ends of the dual-axis motor rotate synchronously in the same direction, or they rotate independently.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the dual-axis motor in the transmission box simultaneously drives the rotating ends of the scraper and the conductive slip ring. On the one hand, it causes the drill barrel to rotate for drilling and sampling. After the transmission box is reversed, the scraper rotates to scrape the mineral sample off the inner wall of the sampling groove, improving sampling efficiency. When an independently rotating dual-axis motor is used, the scraper can be inactive when the drill barrel is working, and vice versa, avoiding wasted electricity.
[0010] Furthermore, laser rangefinders are symmetrically installed at both ends of one side of the transmission box, and an angle sensor is installed on one side of the transmission box between the pair of laser rangefinders.
[0011] The beneficial effects of adopting the above-mentioned further solution are that the laser rangefinder on one side of the transmission box can measure the distance between the drill barrel and the ground or target in real time, and the angle sensor can accurately detect the tilt angle of the transmission box, providing accurate data support for operators, helping them to accurately control the sampling depth and angle, ensuring the accuracy and standardization of sampling, and avoiding sample deviation due to operational errors.
[0012] Furthermore, a retaining ring is fitted onto one end of the rotating shaft, and first electric telescopic rods are inserted into both sides of the retaining ring. A push plate is slidably inserted into one end of the rotating shaft inside the drill barrel, and one end of a pair of first electric telescopic rods passes through the drill barrel and connects to one side of the push plate. The beneficial effect of adopting the above-mentioned further solution is that the fixing ring at one end of the rotating shaft, the first electric telescopic rod and the push plate cooperate with each other. After sampling is completed, the first electric telescopic rod extends to push the push plate, which can smoothly push out the mineral sample in the drill barrel and avoid the mineral samples from different locations from mixing together.
[0013] Furthermore, it also includes a support mechanism, which includes a base. The bottom end of the fixing frame is connected to one side of the upper end of the base. A first mounting seat is fixedly installed on the upper end of the base. A second electric telescopic rod is hinged inside the first mounting seat through a pin. A first servo motor is fixedly installed on one side of the first mounting seat. The output end of the first servo motor is connected to the second electric telescopic rod. A pair of fixing sleeves are fixedly installed at both ends of the base for connecting anchor bolts.
[0014] The beneficial effects of adopting the above-mentioned further solution are that, in the support mechanism, the fixing sleeves at both ends of the base can be inserted with ground nail fixing devices to enhance the stability of the device in complex terrain in the field and prevent the device from shaking or shifting during the exploration process. The first servo motor drives the second electric telescopic rod to extend and retract, which can flexibly adjust the height of the adjustment mechanism and the sampling mechanism to adapt to sampling points at different heights and expand the applicability of the device.
[0015] Furthermore, it also includes an adjustment mechanism, which includes a housing, the bottom of which is connected to the top of the second electric telescopic rod, and a plate is rotatably connected to the top of the housing.
[0016] The beneficial effects of adopting the above-mentioned further solution are that the housing of the adjustment mechanism is connected to the second electric telescopic rod to realize the overall height adjustment; the plate can rotate relative to the housing and can adjust the angle according to the actual terrain and exploration requirements, providing a stable and suitable working plane for the sampling mechanism, ensuring that the sampling process is carried out smoothly and improving the sampling success rate.
[0017] Furthermore, linear motors are fixedly installed on both sides of the flat plate, and a movable frame is slidably installed between a pair of linear motors. The movable ends of the pair of linear motors are respectively connected to the two ends of the movable frame. A second mounting base is fixedly installed on the upper end of the movable frame, and the two sides of the bottom end of the transmission box are rotatably connected to the inner sides of the second mounting base.
[0018] The beneficial effect of adopting the above-mentioned further solution is that the linear motor on the flat plate drives the sliding frame to adjust the horizontal position of the transmission box so that it is aligned with the target sampling point. The transmission box is rotatably connected to the second mounting base and, in conjunction with the second servo motor, can achieve multi-angle rotation, enabling the drill barrel to sample at the angle of the slope, thereby improving the flexibility and adaptability of the sampling device.
[0019] Furthermore, a second servo motor is fixedly installed on one side of the second mounting base, and the output end of the second servo motor is connected to the transmission box. A third servo motor is fixedly installed at the bottom of the inside of the box, and the output end of the third servo motor is connected to the flat plate.
[0020] The beneficial effects of adopting the above-mentioned further scheme are that the second servo motor drives the transmission box to rotate, which can flexibly adjust the drilling direction of the drill barrel; the third servo motor drives the plate to rotate, which facilitates the conversion of the direction of the transmission box. The two work together to enable the sampling device to sample weathered crust rare earth minerals at different locations and angles in complex and ever-changing field environments, thus meeting diverse exploration needs.
[0021] Furthermore, a lid is hinged to the upper side of the storage box via a pair of hinges, and a controller is fixedly installed at one end of the storage box. The controller is electrically connected to each motor and each sensor.
[0022] The beneficial effects of adopting the above-mentioned further solution are that the lid at the top of the storage box is hinged, which can effectively protect the samples and tools stored inside. The controller is used to uniformly control the working status of various components such as motors and electric telescopic rods. Operators can conveniently set and adjust sampling parameters through the controller to achieve automated operation, reduce the difficulty of operation, and improve work efficiency and the accuracy of exploration operations.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The weathered crust type rare earth ore field exploration and sampling device has a base that provides a stable support foundation for the entire device. The fixed frame is installed on the base, and the storage box at the top can classify and store different exploration samples through the internal storage slot. The box of the adjustment mechanism is connected to the second electric telescopic rod. The first servo motor drives the second electric telescopic rod to change the height of the box. The plate can be rotated to adjust the angle. The linear motor drives the moving frame to move. The second servo motor drives the transmission box to rotate. The third servo motor drives the plate to rotate, realizing precise adjustment of the position and angle of the sampling mechanism to adapt to different terrains and exploration needs. The transmission box of the sampling mechanism drives the drill barrel to rotate and sample through the rotating shaft. After the grooving is completed, the direction of the transmission box is rotated so that the scraper is inserted into the grooving. The rotation of the scraper is used to stir the sand and soil in the grooving. The vacuum cleaner, through the three-way pipe and connecting pipe, works with the dust collection disc to promptly pick up the sand and soil generated by the scraper and collect the sand and soil samples in the grooving.

[0039] Specifically, the working principle of this weathered crust type rare earth ore field exploration and sampling device is as follows: Figure 1-8As shown, in use, the first servo motor 104 of the support mechanism 1 drives the second electric telescopic rod 105 to extend and retract, adjusting the height of the housing 306. The third servo motor 307 drives the plate 301 to rotate, which in turn drives the moving frame 303 to move via the linear motor 302. The second servo motor 305 drives the transmission box 401 to rotate, adjusting the drill cylinder 404 of the sampling mechanism 4 to a suitable sampling position and angle. Simultaneously, fixing devices such as ground nails are inserted into the fixing sleeves 102 at both ends of the base 101 to enhance the stability of the device in complex terrain. After determining the position, the dual-axis motor 414 inside the transmission box 401 drives the rotating end of the conductive slip ring 413, causing the rotating shaft 403 and the drill cylinder 404 to rotate, drilling and sampling the bottom of the sampling slot 5 of the rare earth ore body 6. During this process, the laser range sensor 407 and the angle sensor 410 monitor the distance between the drill cylinder 404 and the target object and the tilt angle of the transmission box 401 in real time to ensure sampling accuracy. To ensure accuracy in depth and angle, after drilling, the transmission box 401 is turned around, and the dual-axis motor 414 drives the scraper 406 to rotate, scraping the mineral sample from the inner wall of the sampling borehole. At the same time, the vacuum cleaner 402, through the three-way pipe 408, connecting pipe 409, and suction disc 415, promptly removes the sand and mineral sample generated by the scraper 406. After sampling, the second electric telescopic rod 105 lowers its height, and the first electric telescopic rod 412 extends to push the push plate 411, pushing out the mineral sample from the drill barrel 404. The sample, along with the mineral sample absorbed by the vacuum cleaner 402 from the inner wall of the groove, is manually transferred and stored in the storage slot of the storage box 202 for marking. Throughout the sampling process, the operator can control each motor and electric telescopic rod component through the controller 204 and receive and process the monitoring data from the laser rangefinder sensor 407 and the angle sensor 410. The lid 203 of the storage box 202 protects the samples and tools, ensuring that the field exploration sampling work is completed efficiently and accurately.
[0040] Before sampling a ore body sampling area, the sampling range and method of the ore body are generally planned and designed first, and the sampling locations are marked. Then, this utility model is used to sample piece by piece. When it is necessary to move the drill pipe to the next point, a fork rod (or manually) can be used to support the first stage of the second electric telescopic rod at an appropriate angle to help it maintain a stable angle. When it is extended or retracted to the point, the drill pipe is lowered, and the same operation is repeated for sampling.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
