DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-3 As shown, in this embodiment, a lifting device with an adjustment function is provided, comprising: a base 1, four bases 3 are installed on the lower side of the base 1, the bases 3 are distributed at the corners of the base 1, moving components are arranged on both sides of the base 1, a rotating drum 6 is rotatably matched on the upper part of the base 1, a sampling component is arranged on the rotating drum 6, and a notch 101 corresponding to the sampling component is arranged in the vertical direction of the base 1, and the notch 101 runs through the base 1;

[0027] Two arc racks 4 are installed on the upper side of the base 1, and the gear teeth of the arc racks 4 are located on the side of the inner wall thereof. The rotating drum 6 is located between the two arc racks 4. Two first motors 12 are installed on the side of the rotating drum 6. A gear 1201 is installed at the output end of the first motor 12. The gear 1201 is meshed with the inner wall of the arc rack 4. The surface of the arc rack 4 is provided with scale lines.

[0028] The angle adjustment range of the rotating drum 6 in the vertical state is ±90 degrees (including +90 degrees and -90 degrees). When the rotating drum 6 is rotated to the horizontal state, it can be used to take out the sample in the sampling assembly.

[0029] One aspect of the application of this embodiment is: when sampling, according to the required sampling angle, the first motor 12 is controlled to drive the gear 1201 to rotate. Since the gear 1201 is meshed with the arc rack 4, the gear 1201 rotates and drives the rotating drum 6 to rotate, thereby adjusting the inclination angle of the sampling component. Then, the accuracy of the adjustment of the inclination angle of the rotating drum 6 can be confirmed according to the scale line. After confirmation, the sampling component is controlled to work for sampling.

[0030] In this embodiment, a limiting groove 401 is provided on the side of the arc rack 4, and two rod bodies 602 are installed on the side of the rotating drum 6. A bearing 10 is installed on the circumference of the rod body 602, and a rotating wheel 11 is installed on the circumference of the bearing 10. The lower part of the rotating wheel 11 is located in the limiting groove 401 corresponding to it. The bearing 10 is used to reduce the friction between the rotating wheel 11 and the rod body 602, and the rotating wheel 11 is used to improve the stability of the rotating drum 6 during rotation, thereby reducing the probability of the gear 1201 and the arc rack 4 being out of meshing state.

[0031] In this embodiment, two rotating seats 5 are installed on the upper side of the base 1, and the rotating drum 6 is located between the two rotating seats 5. Two rotating columns 601 are installed on the side of the rotating drum 6. The upper part of the rotating seat 5 is sleeved on the circumference of the rotating column 601. The center of the arc rack 4 is colinear with the axis of the rotating column 601. The rotating drum 6 rotates with the rotating column 601 as the center. The bottom of the rotating drum 6 is lifted by the cooperation of the rotating seat 5 and the rotating column 601, thereby ensuring that the rotating drum 6 can be rotated to a horizontal state.

[0032] The sampling assembly of this embodiment includes a first electric push rod 7 installed on the upper end of the rotating drum 6, a second motor 8 is installed at the output end of the first electric push rod 7, and a sampling tube 9 is installed at the output end of the second motor 8. The second motor 8 and the sampling tube 9 are both slidably fitted in the rotating drum 6. The sampling tube 9 is driven to rotate by the operation of the second motor 8. The first electric push rod 7 extends and pushes the second motor 8 to make the sampling tube 9 slide downward and out of the rotating drum 6, so that the sampling tube 9 passes through the slot 101 for sampling.

[0033] The moving component of this embodiment includes an L-shaped support plate 102 installed on the side of the base 1, and a second electric push rod 2 is installed on the upper side of the L-shaped support plate 102. The output shaft of the second electric push rod 2 vertically penetrates the L-shaped support plate 102, and a lifting plate 201 located below the L-shaped support plate 102 is installed at the output end of the second electric push rod 2. Two universal wheels 203 are movably matched on the lower side of the lifting plate 201. The second electric push rod 2 is located between the two universal wheels 203. The lifting plate 201 and the universal wheels 203 are pushed downward by extending the second electric push rod 2, so that the universal wheels 203 contact the ground to lift the base 1, and the base 3 is lifted off the ground, thereby facilitating the movement of the lifting device.

[0034] In this embodiment, two guide columns 202 are installed on the upper side of the lifting plate 201, and the second electric push rod 2 is located between the two guide columns 202. The guide columns 202 vertically penetrate the L-shaped support plate 102. The guide columns 202 improve the stability of the lifting plate 201 and the universal wheel 203 when sliding up and down.
