Description

Technical Field

[0001] The present application relates to the technical field of roadbed sampling, and in particular to a compaction sampling tool. Background Art

[0002] Compaction degree, as a key parameter to measure the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, is usually expressed as a percentage and is one of the core indicators for evaluating the quality of roadbed and pavement construction. It directly reflects the density state of the on-site compaction operation: the higher the compaction degree, the greater the density of the material, the better the overall performance, and thus the bearing capacity and stability of the road are also improved accordingly. The compaction degree standards vary for different types of roads. For example, due to the characteristics of high-speed vehicle travel on highways, the requirements for roadbed compaction degree are particularly strict. Therefore, in the actual construction process, the roadbed compaction degree standards must be set scientifically and reasonably according to the specific type of road and its usage requirements.

[0003] Currently, there are various methods for testing compaction, among which the sand filling method and the knife ring method are particularly common. The knife ring method is a widely used testing technology, and its tool combination includes a knife ring, a ring cover, a hammer, a soil trimming knife, a ruler, and a scale. In specific operation, the knife ring is first placed steadily on the cleaned soil surface, and then the ring cover is placed on the top of the knife ring; then, the top of the ring cover is repeatedly struck with a hammer to vertically embed the knife ring into the soil until the top surface of the ring cover is flush with the ground surface. Afterwards, the ring cover is gently removed, and the excess soil around the knife ring is carefully trimmed with a soil trimming knife, and a ruler is used to accurately cut a soil sample column at the bottom of the knife ring. After a series of treatments, the soil sample column at the bottom of the knife ring can be accurately cut using a scale to determine whether the compaction of the roadbed meets the standard. However, after in-depth research and careful analysis, the inventors found that the above-mentioned knife ring method for testing compaction still has certain defects and shortcomings. In the process of using the knife ring method for compaction testing, the operation of manually striking the ring cover to embed the knife ring poses certain safety hazards. Since it is difficult to maintain consistent hammering points and it is easy to accidentally injure the operator's hands, this link urgently needs to be improved and optimized. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] A compaction sampling tool includes a sampling tank, which is installed on a pressing device. The pressing device consists of a supporting mechanism, a connecting mechanism, an adjustment mechanism and a pressure plate. The top of the supporting mechanism is integrally formed with the outer side wall of the connecting mechanism, and the sampling tank is plugged into one end of the surface.

[0008] Furthermore, the accommodating member includes an accommodating cavity and two notches. The accommodating cavity is provided at one end of the base surface, and two notches are provided at both ends of the accommodating cavity, which fits with the outer wall of the sampling tank.

[0009] Furthermore, the connecting mechanism includes an outer shell, a cover plate and an installation compartment, the outer wall of the outer shell and the top of the connecting frame are integrally formed, the inner wall of the cover plate is bolted to the outer end of the outer shell, the installation compartment is provided between the outer shell and the cover plate, and the adjustment mechanism is installed inside the installation compartment.

[0010] Furthermore, the adjustment mechanism includes a gear, a connecting column, an adjusting column, a pressure rod, a rack and a limit piece. The gear is installed inside the installation bin, and its two ends are integrally formed with the connecting column and the opposite ends of the adjusting column respectively. The separated ends of the connecting column and the adjusting column are hinged to the two sides of the shell respectively. The side wall of the adjusting column has a hole, and the outer wall of the pressure rod fits with the inner wall of the hole. The rack is installed inside the installation bin and meshes with the gear.

In addition, the design of the container enables the sampling can to fit tightly and be stably installed on the support mechanism, further enhancing the stability and reliability of the sampling. This method solves the problem that it is difficult to keep the hammer point consistent and there are certain safety hazards in the operation of manually knocking the ring cover to embed the ring knife.

DETAILED DESCRIPTION

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

[0024] Example:

[0025] See also Figure 1 、 Figure 3 A compaction sampling tool includes a sampling pot 1 made of a durable material, such as stainless steel or a high-strength alloy, to ensure it can withstand the pressure when pressed into the soil. The sampling pot 1 is cylindrical in shape with a knife-like bottom for easy insertion into the soil.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A compaction sampling tool, the sampling tank 1 is installed on the pressing device 2, the pressing device 2 consists of a supporting mechanism 21, a connecting mechanism 22, an adjusting mechanism 23 and a pressing plate 24; the supporting mechanism 21 includes a base 211, a connecting frame 212 and a accommodating member 213; the accommodating member 213 includes a accommodating cavity 2131 and two notches 2132; the connecting mechanism 22 includes a shell 221, a cover plate 222 and an installation compartment 223; the adjusting mechanism 23 includes a gear 231, a connecting column 232, an adjusting column 233, a pressing rod 234, a rack 235 and a limiting member 236; the limiting member 236 includes a locking bolt 2361 and a concave ring 2362.

[0027] Among them, the design of the support mechanism 21 is intended to ensure the stability and accuracy of the sampling can 1 when it is pressed into the soil. The base 211 is the basic part of the support mechanism 21 and is made of high-strength, corrosion-resistant material. The base 211 is rectangular or circular in shape, and has anti-slip grooves on the bottom to increase friction with the ground and prevent sliding during the sampling process. A receptacle 213 is provided at one end of the surface of the base 211 for inserting and supporting the sampling can 1. The connecting frame 212 is made of alloy material. The bottom end of the connecting frame 212 and the other end of the base 211 are integrally formed by welding to form a stable and sturdy whole. The top end of the connecting frame 212 and the outer wall of the connecting mechanism 22 are integrally formed by welding to ensure that the connecting mechanism 22 can be stably installed on the connecting frame 212. A receptacle 2131 is provided at one end of the surface of the base 211, and its shape and size match the outer wall of the sampling can 1 to ensure that the sampling can 1 can be fully inserted and reach the required sampling depth. A notch 2132 is provided inside the accommodating cavity 2131 to facilitate the placement and removal of the sampling can 1 .

[0028] The connecting mechanism 22 is designed to provide a stable and easily maintained platform for installing and adjusting key components of the pressing device 2, such as the adjustment mechanism 23. The housing 221 and the top of the connecting frame 212 are integrally formed to form an enclosed space. A cover plate 222 is bolted to the outer end of the housing 221, facilitating disassembly and maintenance. A mounting compartment 223, located between the housing 221 and the cover plate 222, is used to install and adjust the mechanism 23.

[0029] Among them, the design of the adjustment mechanism 23 is intended to adjust the position and force of the pressure plate 24 through precise mechanical transmission, so as to ensure that the sampling tank 1 can be accurately and stably pressed into the soil. The gear 231 is installed inside the installation chamber 223 and is integrally formed with the opposite ends of the connecting column 232 and the adjusting column 233. The separated ends of the connecting column 232 and the adjusting column 233 are hinged to the two sides of the outer shell 221 respectively, allowing them to rotate within a certain range. The side wall of the adjusting column 233 has a hole, and the outer wall of the pressure rod 234 fits with the inner wall of the hole, which is used to manually adjust the rotation of the adjusting column 233. The rack 235 is installed inside the installation chamber 223 and meshes with the gear 231. When the position of the adjusting column 233 changes, the gear 231 will rotate and drive the rack 235 to move up and down, thereby adjusting the position of the pressure plate 24. A stopper 236 is installed at the hinged joint between the housing 221 and the connecting post 232 to limit the rotational range of the adjustment mechanism 23. A concave ring 2362 is formed on the outer wall of the connecting post 232, and its shape and size match the bottom end of the locking bolt 2361. The outer wall of the locking bolt 2361 is threadedly engaged with the inner wall of a threaded hole in the side surface of the housing 221. When the locking bolt 2361 is tightened, its bottom end abuts against the inside of the concave ring 2362, thereby limiting further rotation of the connecting post 232 and preventing excessive movement of the pressure plate 24.

[0030] The pressure plate 24 is the output portion of the pressing device 2, used to press the sampling can 1 into the soil. The pressure plate 24 is cross-shaped, with its bottom vertically aligned with the top of the sampling can 1, ensuring that the pressure plate 24 can accurately transmit force to the sampling can 1 when pressing into the soil.

[0031] The working principle of the compaction sampling tool: During the soil sampling process, the sampling tank 1 must first be accurately inserted into the accommodating cavity 2131. Subsequently, the operator rotates the pressure rod 234, and this action will further drive the adjusting column 233 to rotate. The rotation of the adjusting column 233, in turn, drives the gear 231 connected to it to start rotating. As the gear 231 rotates, the rack 235 meshing with it begins to move up and down. The bottom end of the rack 235 is fixedly connected to the pressure plate 24, so the up and down movement of the rack 235 will be directly converted into the up and down movement of the pressure plate 24. When the pressure plate 24 receives a downward movement instruction, it will move downward vertically and steadily until it is tightly pressed against the surface of the sampling tank 1. This strong pressure is enough to press the sampling tank 1 firmly into the soil, thereby completing the soil sampling process.

[0032] It should be noted that the specific model and specifications of the gear 231 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
