Description

Technical Field

[0001] The utility model belongs to the technical field of land surveying and mapping, and particularly relates to soil layer thickness measuring equipment for land surveying and mapping. Background Art

[0002] Land surveying involves using various scientific and technological equipment to obtain graphical and positional information reflecting the ground's current state by measuring existing ground features and boundaries. This information is used for project planning, design, and administrative management. Measuring soil thickness is an essential step in land surveying. Existing soil thickness measurement equipment is mostly handheld soil sampling drills. To measure soil thickness, a handheld soil sampling drill is used to drill a hole in the soil, then remove the soil from the sampling tube and measure the soil thickness.

[0003] Most of the existing handheld soil sampling drills are directly composed of a device main unit and a sampling barrel, and there is no supporting structure on the surface. When the operator uses it to perform drilling sampling, he directly holds the two sides of the device main unit and aligns the sampling barrel connected to the surface of the device main unit with the appropriate position on the ground to directly perform drilling sampling. Therefore, the operator relies entirely on the strength of the operator to maintain the vertical characteristics of the drill rod of the drill rig. In addition, when the device main unit vibrates during operation, the operator needs to use a lot of force to control the stability, which requires a high level of arm strength from the operator and makes the operation difficult. Utility Model Content

[0004] The utility model proposes a soil thickness measuring device for land surveying in order to solve the problems in the prior art that, when drilling and sampling, the vertical characteristics of the drill rod of the drilling rig are maintained entirely by the strength of the operator, and when the main unit of the equipment vibrates during operation, the operator needs to use a large amount of force to control the stability, which requires a high arm strength of the operator and is difficult to operate.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a soil thickness measuring device for land surveying and mapping, comprising:

[0006] Handheld soil sampling drill body and support structure;

[0007] A fixed structure is arranged on the surface of the supporting structure;

[0008] The sampling cylinder can be detachably mounted on the surface of the handheld soil sampling drill body;

[0009] The support structure includes a mounting plate, two telescopic rods are fixedly connected to the mounting plate, the two telescopic rods are fixedly connected to the same support base, and the mounting plate is detachably mounted on the handheld soil sampling drill body through a fixing structure.

[0010] As a preferred embodiment, the fixed structure includes a first fixed plate and a force-bearing plate, two first fixed plates are fixedly connected to the mounting plate, a sliding rod is slidably connected to the first fixed plate, and a second fixed plate is fixedly connected to the sliding rod.

[0011] In order to facilitate the disassembly and assembly of the mounting plate and the handheld soil sampling drill body, further, a force-bearing plate is fixedly connected to the mounting plate, a threaded rod is threadedly connected to the force-bearing plate, and the two second fixed plates are fixedly connected to the same connecting plate, and the threaded rod is rotatably connected to the connecting plate.

[0012] As a preferred embodiment, the cross-sectional shape of the second fixing plate is set to be "L"-shaped, and the first fixing plate and the second fixing plate are both slidably connected to the handheld soil sampling drill body.

[0013] As a preferred embodiment, a pressing plate is fixedly connected to the support base, and the end of the support base is configured as a circular ring.

[0014] In order to improve the stability of the connection between the support base and the ground, further, a plurality of fixing blocks are fixedly connected to the support base, and the cross-sectional shape of the fixing blocks is set to be conical.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model provides a supporting structure. When an operator uses the handheld soil sampling drill body to drill soil and sample, thereby measuring the thickness of the soil layer, the operator directly installs the mounting plate to the surface of the handheld soil sampling drill body through the fixed structure. After the operator places the support base at a suitable position on the ground, the sampling tube passes through the support base. When the handheld soil sampling drill body is drilling through the sampling tube, the two telescopic rods cooperate with the mounting plate and the support base to support and limit the handheld soil sampling drill body. The operator does not need to use a lot of force to control, thereby improving the operator's convenience in use.

[0017] 2. The utility model provides a fixing structure. When the operator uses the handheld soil sampling drill body to drill soil and sample, thereby measuring the thickness of the soil layer, the two first fixing plates and the two second fixing plates are aligned with the appropriate positions of the surface of the handheld soil sampling drill body, so that the two first fixing plates and the two second fixing plates are clamped to the surface of the handheld soil sampling drill body. The operator rotates the threaded rod. When the threaded rod rotates, the connecting plate drives the two second fixing plates to move closer to the first fixing plate. When the two first fixing plates and the two second fixing plates are tightly fitted with the surface of the handheld soil sampling drill body, the connection and fixing of the mounting plate and the handheld soil sampling drill body are completed. When the operator finishes using the handheld soil sampling drill body, the mounting plate can be disassembled, thereby facilitating the operator to transport and carry the handheld soil sampling drill body and the mounting plate.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] See also Figure 1-3 The utility model provides a soil thickness measuring device for land surveying and mapping, comprising:

[0026] Handheld soil sampling drill body 1 and support structure 2;

[0027] The fixing structure 3 is arranged on the surface of the supporting structure 2;

[0028] The sampling tube 6 is detachably mounted on the surface of the handheld soil sampling drill body 1;

[0029] The support structure 2 includes a mounting plate 201 , to which two telescopic rods 202 are fixedly connected. The two telescopic rods 202 are fixedly connected to the same support base 203 . The mounting plate 201 is detachably mounted to the handheld soil sampling drill body 1 through a fixing structure 3 .

[0030] Specifically, such as Figure 1 、 2 As shown in FIG3 , the fixing structure 3 includes a first fixing plate 301 and a force plate 304. Two first fixing plates 301 are fixedly connected to the mounting plate 201. A sliding rod 302 is slidably connected to the first fixing plate 301. The sliding rod 302 is fixedly connected to the second fixing plate 303. The mounting plate 201 is fixedly connected to the force plate 304. A threaded rod 305 is threadedly connected to the force plate 304. The two second fixing plates 303 are fixedly connected to the same connecting plate 306. The threaded rod 305 is rotatably connected to the connecting plate 306. The cross-sectional shape of the second fixing plate 303 is set to be "L"-shaped. The first fixing plate 301 and the second fixing plate 303 are both slidably connected to the handheld soil sampling drill body 1. By setting the sliding rod 302, the sliding rod 302 can provide a certain limiting effect on the second fixing plate 303, so that when the threaded rod 305 rotates, the connecting plate 306 can drive the two second fixing plates 303 to move closer to or away from the first fixing plate 301.

[0031] See Figure 1-3 When the operator uses the handheld soil sampling drill body 1 to drill and sample the soil, thereby measuring the thickness of the soil layer, the two first fixing plates 301 and the two second fixing plates 303 are aligned with appropriate positions on the surface of the handheld soil sampling drill body 1, so that the two first fixing plates 301 and the two second fixing plates 303 are all snapped onto the surface of the handheld soil sampling drill body 1. Then, the operator rotates the threaded rod 305. When the threaded rod 305 rotates, the connecting plate 306 drives the two second fixing plates 303 to move closer to the first fixing plate 301. When the two first fixing plates 301 and the two second fixing plates 303 are tightly fitted with the surface of the handheld soil sampling drill body 1, the connection and fixing process of the mounting plate 201 and the handheld soil sampling drill body 1 is completed.

[0032] After the operator places the support base 203 at a suitable position on the ground, the sampling tube 6 passes through the support base 203, opens the handheld soil sampling drill body 1, and allows the handheld soil sampling drill body 1 to drill and sample through the sampling tube 6. The telescopic rod 202 retracts following the movement of the sampling tube 6. When the sampling tube 6 drills a hole to a suitable depth, the operator releases the connection between the handheld soil sampling drill body 1 and the sampling tube 6, then pulls out the sampling tube 6 with the puller, and takes out the soil inside the sampling tube 6 for measurement.

[0033] When the operator needs to disassemble the mounting plate 201 and the handheld soil sampling drill body 1, the operator rotates the threaded rod 305 in the opposite direction. When the threaded rod 305 moves away from the force-bearing plate 304, the two second fixing plates 303 are driven to move synchronously. When the two first fixing plates 301 and the two second fixing plates 303 are released from the tight fit with the handheld soil sampling drill body 1, the mounting plate 201 can be removed.

[0034] Example 2:

[0035] See also Figure 1-4 The utility model provides a soil thickness measuring device for land surveying and mapping, comprising:

[0036] Handheld soil sampling drill body 1 and support structure 2;

[0037] The fixing structure 3 is arranged on the surface of the supporting structure 2;

[0038] The sampling tube 6 is detachably mounted on the surface of the handheld soil sampling drill body 1;

[0039] The support structure 2 includes a mounting plate 201 , to which two telescopic rods 202 are fixedly connected. The two telescopic rods 202 are fixedly connected to the same support base 203 . The mounting plate 201 is detachably mounted to the handheld soil sampling drill body 1 through a fixing structure 3 .

[0040] Specifically, such as Figure 2 and 3 As shown, a stepping plate 4 is fixedly connected to the support base 203, and the end of the support base 203 is set to a circular ring shape. A number of fixed blocks 5 are fixedly connected to the support base 203, and the cross-sectional shape of the fixed block 5 is set to a cone. By setting the stepping plate 4 and the fixed block 5, when the operator steps on the stepping plate 4, it is convenient to limit and fix the support base 203. At the same time, under the action of the fixed block 5, when the support base 203 is tightly fitted with the ground, the fixed block 5 can be inserted into the inside of the ground, thereby further improving the stability of the connection between the support base 203 and the ground.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood 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 present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
