Description

Technical Field

[0001] This utility model relates to the technical field of civil engineering testing and sampling equipment, specifically a civil engineering testing and sampling device. Background Technology

[0002] Civil engineering is a general term for civil engineering and building engineering. It is an engineering discipline that constructs various facilities and places for human life, production, protection and other activities. Civil engineering involves the existence, activities and development of all sectors of the national economy. Civil engineering testing and sampling equipment is a type of equipment used in the land construction process. Through land construction testing and monitoring equipment, it is usually necessary to sample and test the soil of the civil engineering road surface during the road construction process.

[0003] Road surface soil typically has a certain degree of hardness, making manual sampling with handheld sampling equipment labor-intensive, cumbersome, and inconvenient for multi-site sampling. Furthermore, existing equipment leaves the sampling tube filled with soil after sampling, making soil removal difficult and limiting its practicality. Therefore, we offer a civil engineering testing sampling device to solve these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a civil engineering testing and sampling device.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a civil engineering testing and sampling device, comprising a support frame, a connecting ring fixedly connected to the center of the top wall of the support frame, a drive wheel fixedly connected to the top of the connecting ring, a fixed frame rotatably connected to the outer surface of the connecting ring, a drive motor fixedly connected to the top right side of the fixed frame, the bottom output end of the drive motor meshing with the drive wheel via a gear, a support plate fixedly connected to the bottom end of the support frame, four guide grooves arrayed inside the support plate, a limit ring fixedly connected to the center of the top wall of the support plate, an adjusting plate rotatably connected to the outer surface of the limit ring above the support plate, a toothed ring fixedly connected to the inner wall of the top of the adjusting plate, an adjusting mechanism provided on the inner wall of the support frame near the toothed ring, four limit grooves arrayed inside the adjusting plate, a sampling mechanism provided between the guide grooves and the limit grooves, and a material ejection mechanism provided at the center of the support plate inside the sampling mechanism.

[0008] Furthermore, the fixed frame is arranged in an "L" shape, and the fixed frame is connected to the external lifting mechanism. The outer wall of the drive motor is connected to the side wall of the fixed frame through a bracket.

[0009] Furthermore, the adjustment mechanism includes a worm gear, and the inner wall of the support frame is rotatably connected to the worm gear by a rotating ring. A rotating wheel is provided at the front end of the worm gear, a worm wheel is engaged at the left end of the worm gear, and a connecting wheel is fixedly connected to the bottom of the worm wheel.

[0010] Furthermore, the worm gear and the connecting wheel are fixedly connected by a plug rod, and the inner wall of the support frame is rotatably connected to the plug rod by a support plate, and the connecting wheel meshes with the gear ring.

[0011] Furthermore, the sampling mechanism includes a guide block, which is slidably connected to the inner wall of the guide groove. A limiting rod is fixedly connected to the top wall of the guide block within the limiting groove, and the limiting rod is slidably connected to the inner wall of the limiting groove. A sampling insert plate is fixedly connected to the bottom of the guide block. The sampling insert plate is arc-shaped, and its top wall is slidably connected to the bottom wall of the support plate. A guide ring is provided on the outer wall of the sampling insert plate, and the guide ring is spiral-shaped.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this civil engineering testing and sampling equipment has the following advantages:

[0016] I. This utility model utilizes an external electric screwdriver to drive a worm gear to rotate, which in turn drives a connecting wheel to rotate via a worm wheel. The connecting wheel, in turn, drives an adjusting disc to rotate via a gear ring. The adjusting disc, via a limiting groove, drives a limiting rod to move. The limiting rod, via a guide block, causes the sampling plate to separate. Pulling down the moving rod causes the material ejector to separate large clumps of soil adhering to the inner wall of the sampling plate. This solves the problem that existing sampling cylinders are difficult to remove because their inner walls are filled with soil after sampling. This invention has the advantage of facilitating sample removal.

[0017] II. This utility model uses a drive motor to drive a drive wheel to rotate a connecting ring, which in turn drives a support frame to rotate. The support frame moves a guide block via a support plate, and the guide block rotates a sampling plate. An external lifting mechanism moves the support frame down via a fixed frame, and the support frame drives the sampling plate to insert into the soil for sampling. After sampling, the external lifting mechanism moves the device out of the soil. This solves the problem of high labor intensity and inconvenience for multi-location sampling when using traditional manual handheld sampling equipment, and has the advantage of saving manpower.
