Description

Technical Field

DETAILED DESCRIPTION

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0029] like Figures 1 to 10 As shown, a soil sampler for land surveying comprises a frame 1, a driving mechanism 2 is provided inside the frame 1 for longitudinal sliding, an adjusting mechanism 3 for controlling the longitudinal sliding of the driving mechanism 2 is provided on the frame 1, a sampling drill 4 is fixedly installed at the output end of the driving mechanism 2, and a plurality of sampling mechanisms 5 are provided inside the sampling drill 4; the sampling mechanism 5 comprises a fixed cylinder 501 fixedly installed inside the sampling drill 4, and a sampling member 502 is provided inside the fixed cylinder 501 for sliding. Fig. 9 As shown, the sampling member 502 includes a flexible sleeve 5021, a mounting groove 5022 is provided inside the flexible sleeve 5021, a plurality of arc-shaped spring pieces 5023 are fixedly provided inside the mounting groove 5022, a metal ring 5024 is fixedly provided at the opening of the flexible sleeve 5021, the metal ring 5024 is used to assist the flexible sleeve 5021 to be inserted into the soil, a conical surface is provided on one side of the inner wall of the fixed tube 501 close to the metal ring 5024, the conical surface is used to guide the flexible sleeve 5021 to shrink into the inside of the fixed tube 501, and the sampling drill 4 corresponds to a plurality of The opening of the sampling piece 502 is provided with a slot 401, and a shielding mechanism 6 is longitudinally provided at the position of the sampling drill 4 corresponding to the slot 401. The sampling drill 4 is located at the rear end of the sampling piece 502 and is provided with a control mechanism 7 for controlling the sliding of the sampling piece 502 in the fixed tube 501. When the control mechanism 7 controls the sampling piece 502 to extend out from the inside of the sampling drill 4, the outer surface of the sampling piece 502 will expand outward. When the control mechanism 7 controls the sampling piece 502 to be retracted into the inside of the sampling drill 4, the fixed tube 501 will cause the part of the sampling piece 502 that expands outward to shrink.

[0030] In summary, if Figures 5 to 9As shown, when the sampling member 502 extends from the sampling drill 4, the metal ring 5024 is used to assist the flexible sleeve 5021 to be inserted into the soil. The arc-shaped spring pieces 5023 can be used to allow the extended portion of the flexible sleeve 5021 to expand rapidly outward, so that the flexible sleeve 5021 can accommodate more soil. At the same time, the plurality of arc-shaped spring pieces 5023 can be used to allow the rear arc-shaped spring pieces 5023 to deform, which can cause the flexible sleeve 5021 to vibrate, thereby further improving the metal ring 5024 and the flexible sleeve 5021. The speed at which the sleeve 5021 is inserted into the soil, when the sampling piece 502 is retracted into the sampling drill 4, the fixed tube 501 can be used to control the flexible sleeve 5021 and the arc-shaped spring piece 5023 to shrink, and then the soil can be squeezed by the flexible sleeve 5021 to effectively remove the air and moisture in the soil. By using the set several arc-shaped spring pieces 5023, when the front arc-shaped spring piece 5023 is deformed, the flexible sleeve 5021 can be caused to shake, thereby further improving the effect of removing air and moisture in the soil.

[0031] like Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes a first motor 301 fixedly mounted on the top of the frame 1, the output end of the first motor 301 passes through the frame 1 and is fixedly mounted with a screw rod 302, the frame 1 is fixedly provided with fixed rods 303 on both sides of the screw rod 302, the drive mechanism 2 includes a mounting frame 201 threadedly connected to the screw rod 302, a second motor 202 is fixedly mounted inside the mounting frame 201, a transmission rod 203 is fixedly mounted on the output end of the second motor 202, and one end of the transmission rod 203 away from the second motor 202 is fixedly mounted with the sampling drill 4, and the mounting frame 201 corresponds to two fixed rods The positions of the holes 303 are provided with sliding holes adapted thereto. When sampling, the frame 1 is moved to a designated position, and then the second motor 202 is used to control the transmission rod 203 and the sampling drill 4 to rotate, and then the first motor 301 is used to control the screw rod 302 to rotate to control the adjustment mechanism 3 to move downward, so that the sampling drill 4 can drill into the soil. After sampling, the first motor 301 is used to control the screw rod 302 to rotate in the opposite direction to control the adjustment mechanism 3 to move upward, so that the sampling drill 4 can be separated from the soil, and the soil can be taken out from the sampling member 502, and then the soil sample can be surveyed (such as Figure 5 as shown).

[0032] like Figures 3 to 6 As shown, the shielding mechanism 6 includes a slot 601 opened on the sampling drill 4, a baffle 602 is longitudinally slidably provided inside the slot 601, and the baffle 602 is located below the plurality of slots 401 and each of which is provided with a through hole 603, and the through hole 603 is the same size as the slot 401. The baffle 602 shields the through hole 603 to prevent soil at other depths from entering the sampling piece 502, thereby ensuring the accuracy of deep soil detection.

[0033] like Figure 5 and Figure 7 As shown, the control mechanism 7 includes a control rod 701 longitudinally slidably arranged inside the sampling drill 4, and flexible parts 702 are fixedly arranged at the positions of the outer surface of the control rod 701 corresponding to the multiple fixed cylinders 501, and the sampling drill 4 is provided with sliding grooves at the positions corresponding to the control rod 701, and the sampling drill 4 is provided with track grooves 402 at the positions corresponding to the multiple flexible parts 702. The track grooves 402 are used to control the flexible parts 702 to bend. By pressing the control rod 701 downward, the flexible part 702 controls the sampling part 502 to extend from the inside of the sampling drill 4, and by pulling the control rod 701 upward, the sampling part 502 is controlled to be retracted into the inside of the sampling drill 4.

[0034] The frame 1, driving mechanism 2 and adjusting mechanism 3 described in the present application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0035] The working process is as follows:

[0036] S1, such as Figure 1 and Figure 2 As shown, when sampling, the frame 1 is moved to a designated point, and then the second motor 202 is used to control the transmission rod 203 and the sampling drill 4 to rotate, and then the first motor 301 is used to control the screw rod 302 to rotate to control the adjustment mechanism 3 to move downward, so that the sampling drill 4 drills into the soil;

[0037] S2, such as Figure 3 , Figure 4 and Figure 6 As shown, when the sampling drill 4 drills to the specified depth, the baffle 602 is pulled upward so that the through hole 603 overlaps with the slot 401. At this time, the friction between the baffle 602 and the slot 601 can make the baffle 602 have a damping effect when it is pulled, so that when the staff stops pulling the baffle 602, the baffle 602 can be kept in the position where the pulling stops;

[0038] S3, such as Figure 5 and Figure 7 As shown, when the through hole 603 overlaps with the slot hole 401, by pressing the control rod 701 downward, the flexible member 702 controls the sampling member 502 to extend from the inside of the sampling drill 4;

[0039] S4, such as Figures 7 to 9As shown, when the sampling member 502 extends from the sampling drill 4, the metal ring 5024 is used to assist the flexible sleeve 5021 to be inserted into the soil. The arc-shaped spring pieces 5023 can allow the extended portion of the flexible sleeve 5021 to expand outward quickly, so that the flexible sleeve 5021 can accommodate more soil. At the same time, the plurality of arc-shaped spring pieces 5023 can be used to allow the rear arc-shaped spring pieces 5023 to be deformed, which can cause the flexible sleeve 5021 to vibrate, thereby further increasing the speed at which the metal ring 5024 and the flexible sleeve 5021 are inserted into the soil.

[0040] S5, such as Figures 5 to 9 As shown, after the sampling piece 502 has finished sampling, the sampling piece 502 is controlled to be retracted into the sampling drill 4 by pulling the control rod 701 upwards;

[0041] S6, such as Figures 5 to 9 As shown, when the sampling member 502 is retracted into the sampling drill 4, the fixed tube 501 can be used to control the flexible sleeve 5021 and the arc-shaped spring piece 5023 to shrink, and then the soil can be squeezed by the flexible sleeve 5021 to effectively remove the air and moisture in the soil. By using the plurality of arc-shaped spring pieces 5023, the front arc-shaped spring pieces 5023 can be deformed to cause the flexible sleeve 5021 to vibrate, thereby further improving the removal effect of air and moisture in the soil.

[0042] S7, such as Figure 3 , Figure 4 and Fig. 9 As shown, when the sampling piece 502 is completely retracted into the sampling drill 4, the baffle 602 is pressed downward so that the baffle 602 blocks the through hole 603, preventing soil from other depths from entering the sampling piece 502, thereby ensuring the accuracy of deep soil detection;

[0043] S8, such as Figures 1 to 9 As shown, after the baffle 602 is adjusted, the first motor 301 controls the screw rod 302 to rotate in the opposite direction to control the adjustment mechanism 3 to move upward, so that the sampling drill 4 can be separated from the soil. At this time, steps S2 to S4 can be repeated to take the soil out of the sampling piece 502, and then the soil sample can be surveyed.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
