[0026] like Figures 1-8 A geological survey machine for mine restoration shown in the figure includes a base plate 1, an exploration mechanism 2, a support mechanism 3, an expansion mechanism 4, and a gripping mechanism 5. The support mechanism 3 includes a lower support seat 305, and the expansion mechanism 4 includes a central steel plate 401. The exploration mechanism 2 is arranged on the base plate 1. There are four support mechanisms 3, and the support mechanisms 3 are symmetrically arranged on the lower surface of the base plate 1. The lower end of the lower support seat 305 is provided with an expansion mechanism 4, and two gripping mechanisms 5 are provided on the central steel plate 401.

[0027] The exploration mechanism 2 includes a center rod 201, which passes through the center of the substrate 1 and forms a sliding fit with the substrate 1. Racks are respectively provided on both sides of the center rod 201, and a collection head 202 is provided at the lower end of the center rod 201. Optionally, the collection head 202 is a drill bit, which is used to drill underground soil for analysis. The rack of the center rod 201 forms a gear meshing with the concave gear 203, and the concave gear 203 is rotatably provided on the upper surface of the substrate 1. The center axis of the concave gear 203 is fixedly connected to the rotating shaft of the collection motor 204. The collection motor 204 is fixedly provided on the upper surface of the substrate 1, and the two concave gears 203 are connected through a synchronous transmission mechanism 205.

[0028] The center rod 201 is expandable. Optionally, the two center rods 201 are connected end to end using threads.

[0029] Among them, the synchronous transmission mechanism 205 is composed of four identical gears meshing in sequence. The four gears are rotatably arranged on the upper surface of the substrate 1. The two outer gears of the synchronous transmission mechanism 205 are coaxially connected to the two concave gears 203 respectively, so the two concave gears 203 can rotate synchronously in opposite directions.

[0030] Specifically, the motor 204 rotates the shaft to drive a concave gear 203 to rotate, and the power is transmitted through the synchronous transmission mechanism 205, so that the other concave gear 203 rotates synchronously in the opposite direction. The two concave gears 203 act together on the center rod 201, causing the center rod 201 to move downward. The collection head 202 works on the ground to drill underground soil for analysis.

[0031] The support mechanism 3 includes two upper support bases 301, which are arranged in parallel on the lower surface of the base plate 1. Each upper support base 301 is hinged to one end of a support rod 302. The two support rods 302 are parallel to each other. The hinge axis of one of the support rods 302 is fixedly connected to the rotation axis of a support motor 303, which is fixedly located on the lower surface of the base plate 1. A hydraulic cylinder 304 is provided in the middle of the support rod 302. The lower ends of the two support rods 302 are rotatably connected to the two ends of the lower support base 305. When the support motor 303 drives one support rod 302 to rotate, the other support rod 302 also rotates synchronously.

[0032] The hydraulic cylinder 304 is retractable to adjust the distance between the two ends of the support rod 302 .

[0033] Specifically, the support motor 303 drives the support rods 302 to rotate. Since the two support rods 302 are parallel to each other, the motion trajectory of the lower support base 305 is a translation motion, and it rotates around the upper support base 301.

[0034] The expansion mechanism 4 includes a central steel plate 401, a central column 403 is slidingly provided at the center position of the central steel plate 401, a downward pressure rod 402 is provided on the upper part of the central column 403, the downward pressure rod 402 corresponds to the support rod 302, a central spring 404 is fixed between the central steel plate 401 and the central column 403, two grooves are provided on the central column 403, a guide rod 405 is inserted into the groove of the central column 403, the guide rod 405 is fixed on the rotating plate 406, the rotating plate 406 is slidingly provided on the central steel plate 401, four pressure rods 407 are slidingly provided on the rotating plate 406 in sequence, a pressure rod spring 408 is fixed between the rotating plate 406 and the pressure rod 407, the round head end of the pressure rod 407 touches the bottom of the downward pressure guide plate 409, the downward pressure guide plate 409 is fixed on the central steel plate 401, the two ends of the groove of the central column 403 are straight segments, and the middle end is a slant segment.

[0035] During the downward sliding of the center column 403, the guide rod 405 first slides in the lower straight groove section of the center column 403, and the guide rod 405 remains stationary; then the guide rod 405 slides in the oblique groove section of the center column 403, and the guide rod 405 rotates; finally, the guide rod 405 slides in the upper straight groove section of the center column 403, and the guide rod 405 remains stationary.

[0036] Rotating support plates 410 are provided on the four sides of the central steel plate 401. Two spring bars 411 are fixed between each support plate 410 and the central steel plate 401. When the support plates 410 are in a vertical position and there is no blocking force, the spring bars 411 drive the support plates 410 to flip, making the support plates 410 parallel to the central steel plate 401. Baffles are provided on the sides of the central steel plate 401 to prevent the support plates 410 from flipping when the central steel plate 401 and the support plates 410 are parallel.

[0037] Specifically, when the support motor 303 drives the support rod 302 to rotate, the support mechanism 3 is unfolded, and the support rod 302 acts on the pressure rod 402 to make the pressure rod 402 and the center column 403 move downward synchronously. When sliding in the lower straight groove section of the center column 403, the guide rod 405 remains stationary; as the support motor 303 continues to drive the support rod 302 to rotate, the guide rod 405 slides in the oblique groove section of the center column 403, and the rotating plate 406 rotates clockwise. The pressure rod 407 is always pressed against the lower surface of the downward pressure guide plate 409 under the drive of the pressure rod spring 408. Therefore, when the rotating plate 406 rotates clockwise, the pressure rod 407 is lifted, and the spring bar 411 drives the support steel plate 410 to flip, so that the support steel plate 410 is parallel to the center steel plate 401. The four supporting steel plates 410 and the center steel plate 401 work together to increase the contact area with the ground and enhance the stability of the system. When the support mechanism 3 is unfolded to a certain angle, the guide rod 405 slides in the upper straight groove section of the center column 403. As the unfolding angle of the support mechanism 3 increases, the rotating plate 406 will no longer rotate. That is, when the support mechanism 3 is unfolded to a certain angle, the four supporting steel plates 410 will fully unfold and be parallel to the center steel plate 401. When the angle of the support mechanism 3 is further increased, the four supporting steel plates 410 will still remain parallel to the center steel plate 401. Only when the support mechanism 3 is unfolded to a certain angle can the device be placed on the ground and begin working, thus avoiding operator error and starting work without fully unfolding the support mechanism 3. The support rod 302 corresponds to the lower pressure rod 402. When the support rod 302 is vertical, the support rod 302 does not contact the lower pressure rod 402. After the support rod 302 rotates, the support rod 302 contacts the lower pressure rod 402, i.e., 302 presses down the lower pressure rod 402.

[0038] When the support mechanism 3 is retracted, the support rod 302 gradually moves away from the lower pressure rod 402. Driven by the center spring 404, the lower pressure rod 402 and the center column 403 move upward synchronously. The groove of the center column 403 drives the guide rod 405 and the rotating plate 406 to rotate counterclockwise. The lower surface of the lower pressure guide plate 409 presses the pressure rod spring 408 to move downward. The lower end of the pressure rod spring 408 acts on the support steel plate 410, so that the support steel plate 410 overcomes the resistance of the center steel plate 401 and flips over; when the support mechanism 3 is fully retracted, the four support steel plates 410 are vertical devices to facilitate the transportation of this device.

[0039] The gripping mechanism 5 includes a gripping rod 501, which is arc-shaped and slidingly arranged on the central steel plate 401. The two ends of the multi-stage electric cylinder 502 are respectively hinged to the central steel plate 401 and the upper end of the gripping rod 501, and the lower end of the gripping rod 501 is pointed.

[0040] Specifically, after the device is completely placed on the ground, the multi-stage electric cylinder 502 is started, the gripping rod 501 slides, and the gripping rod 501 is inserted into the ground, thereby increasing the gripping force between the device and the ground and avoiding jumping after starting the device.

[0041] When the support rod 302 is in the standby state, the support rod 302 is perpendicular to the base plate 1. When the support rod 302 is started, the support motor 303 is started first. The support motor 303 drives the support rod 302 to rotate, so that the support device 3 is unfolded. The support rod 302 acts on the pressure rod 402 to make the pressure rod 402 and the center column 403 move downward synchronously. When sliding in the lower straight groove section of the center column 403, the guide rod 405 remains stationary. As the support motor 303 continues to drive the support rod 302 to rotate, the guide rod 405 slides in the oblique groove section of the center column 403, and the rotating plate 406 rotates clockwise. The pressure rod 407 is always pressed against the lower surface of the downward pressure guide plate 409 under the drive of the pressure rod spring 408. Therefore, when the rotating plate 406 rotates clockwise, the pressure rod 407 is lifted, and the spring bar 411 drives the support steel plate 410 to flip, so that the support steel plate 410 is parallel to the center steel plate 401.

[0042] According to the conditions of the mine ground, adjust the telescopic distance of the hydraulic cylinder 304, then place the device on the ground, start the multi-stage electric cylinder 502, and the gripping rod 501 slides and inserts into the ground to increase the grip of the device with the ground.

[0043] The sampling motor 204 is started to drive a concave gear 203 to rotate, and the power is transmitted through the synchronous transmission mechanism 205, so that the other concave gear 203 rotates synchronously in the opposite direction. The two concave gears 203 act together on the center rod 201, causing the center rod 201 to move downward. The sampling head 202 works towards the ground to drill the underground soil of the mine for analysis.

[0044] When the device is recovered, the support motor 303 is reversed to reverse the support rod 302, and the support rod 302 gradually moves away from the lower pressure rod 402. Driven by the center spring 404, the lower pressure rod 402 and the center column 403 move upward synchronously, and the groove of the center column 403 drives the guide rod 405 and the rotating plate 406 to rotate counterclockwise. The lower surface of the lower pressure guide plate 409 presses the pressure rod spring 408 to move downward, and the lower end of the pressure rod spring 408 acts on the support steel plate 410, so that the support steel plate 410 overcomes the resistance of the center steel plate 401 and flips over; when the support device 3 is fully recovered, the four support steel plates 410 are vertical devices.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
