Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering. More specifically, the utility model is a ground material sampling device. Background Art

[0002] In the field of building construction, especially in engineering projects such as brick masonry, floor paving, and pipeline laying, the demand for bulk materials such as bulk cement, slaked lime, river sand, and manufactured sand is often extremely large. These ground materials are not only the basic materials that make up the main body of the building, but also the key factors to ensure the project quality and durability. Therefore, during the construction process, it is particularly important to conduct strict sampling and inspection of these ground materials.

[0003] Traditional sampling methods usually require at least two workers to cooperate. Among them, one worker is responsible for shoveling the materials, and the other worker is responsible for holding open the material bag for sampling. However, there are many deficiencies in this sampling method during the operation process. Especially in a windy environment, the powder material is extremely prone to generating dust. This not only affects the accuracy of the sampling work, but also poses a serious threat to the health of the workers. The worker holding the bag is exposed to the dust environment for a long time and is extremely prone to inhaling the material dust. In the long run, it may lead to health problems such as respiratory diseases. Summary of the Utility Model

[0004] To solve the technical problems of the low working efficiency of the existing sampling method and the harm to the health of the sampling personnel, the utility model innovatively provides a ground material sampling device. By setting a sampling cylinder and corresponding components, the sampling process is greatly simplified, the sampling efficiency is improved, and the health of the sampling personnel is ensured.

[0005] To achieve the above technical purpose, the utility model discloses a ground material sampling device, including a sampling cylinder. A cover plate for closing the upper opening of the sampling cylinder is provided on the sampling cylinder. A through hole is provided in the center of the cover plate. One side of the middle part of the inner peripheral wall of the sampling cylinder is hinged with a sampling plate. A stop block is fixed on the other side of the middle part of the inner peripheral wall of the sampling cylinder. The stop block abuts against the upper side of the sampling plate. The size and shape of the sampling plate match the cross-sectional shape of the inner peripheral wall of the sampling cylinder. A pulling member is provided in the center of the upper surface of the sampling plate. The pulling member is connected to the lower end of a pull rod. The upper end of the pull rod passes through the through hole of the cover plate.

[0006] Further, for the ground material sampling device of the utility model, the sampling cylinder is a rectangular cylinder welded by a front side wall, a rear side wall, a left side wall, and a right side wall. Installation holes are respectively opened at the middle parts of the front side wall and the rear side wall and near one end of the left side wall. The installation hole on the front side wall and the installation hole on the rear side wall are arranged oppositely. A rotating shaft is installed between the installation holes on the front side wall and the rear side wall. A circular curling is provided at the left end of the sampling plate. The sampling plate is fixed to the middle part of the rotating shaft through the curling.

[0007] Furthermore, for a ground material sampling device of the present utility model, the front end of the rotating shaft penetrates through the front side wall, and the part of the front end of the rotating shaft that penetrates through is pressed into a flat nozzle shape. The rear end of the rotating shaft penetrates through the rear side wall, and the part of the rear end of the rotating shaft that penetrates through is also pressed into a flat nozzle shape.

[0008] Furthermore, for a ground material sampling device of the present utility model, a circular pull ring is welded to the lower end of the pull rod. The connecting member is a semi-circular pull ring, and the semi-circular pull ring penetrates into the circular pull ring and is welded to the center of the sampling plate.

[0009] Furthermore, for a ground material sampling device of the present utility model, the through hole of the cover plate is a rectangular through hole. A retaining pin is welded to the middle of the pull rod in a cross shape. The length of the retaining pin is less than the length of the rectangular through hole and greater than the width of the rectangular through hole. When the retaining pin penetrates through the rectangular through hole and abuts against the cover plate, the sampling plate just abuts against the stop block.

[0010] Furthermore, for a ground material sampling device of the present utility model, when the sampling plate abuts against the stop block, the sampling plate is perpendicular to the sampling cylinder.

[0011] Furthermore, for a ground material sampling device of the present utility model, when the sampling plate hangs naturally, the lower end surface of the sampling plate is exactly flush with the lower end surface of the sampling cylinder.

[0012] Furthermore, for a ground material sampling device of the present utility model, the upper end of the pull rod is bent into a handle in the shape of an inverted triangle with one side open.

[0013] Furthermore, for a ground material sampling device of the present utility model, the periphery of the cover plate and the upper edge of the sampling cylinder are welded by full argon arc welding.

[0014] The difference between the present utility model and the prior art lies in that: at the upper opening of the sampling cylinder of the present utility model, a closed cover plate is provided, and a through hole is opened in the center of the cover plate so that the pull rod can pass through smoothly. In the middle of the inner peripheral wall of the sampling cylinder, a sampling plate is hinged on one side, and a stop block is fixed on the other side. The size and shape of the sampling plate match the cross-section of the inner peripheral wall of the sampling cylinder, and it is connected to the central pulling member on the upper surface of the sampling plate through a pull rod. In practical applications, the operation process of the ground material sampling device is very simple. First, the sampler needs to rotate the sampling plate to the lowest position to prepare for sampling. Then, by pressing down the sampling cylinder, it is inserted into the ground material to be sampled. During the sampling process, since the sampling cylinder adopts a closed design, even in an environment with strong wind, it can effectively prevent powder from being dusty, thereby reducing the risk of the sampler inhaling dust. After sampling, the sampler only needs to hold the sampling cylinder and lift the pull rod upward to pull up the sampling plate. When the sampling plate abuts against the stop block, the upper half chamber of the sampling cylinder is sealed, and the powder is retained in the sealed chamber of the sampling cylinder. At this time, the sampler can take out the sampling cylinder from the ground material to complete the entire sampling process. The advantages of this ground material sampling device are that it only requires one sampler to complete a series of tasks such as sampling and loading, greatly reducing the labor usage and improving the labor efficiency. At the same time, due to its closed design, it ensures that the powder will not be dusty during the sampling process, thus protecting the physical health of the sampler. In addition, the device also has strong applicability. Whether it is for different types of ground materials or for sampling requirements in different environments, it can be adapted by adjusting the size and shape of the sampling cylinder and the sampling plate, making the device have a wide application prospect.

[0023] The following will combine the accompanying drawings of the specification to give a detailed explanation and description of a ground material sampling device of the present utility model.

[0024] As Figures 1-6 shown, the present utility model discloses a ground material sampling device, including a sampling cylinder 1. At the upper opening of the sampling cylinder 1, a closed cover plate 2 is provided. The periphery of the cover plate 2 is welded to the upper edge of the sampling cylinder 1 by full penetration argon arc welding. A through hole 21 is opened in the center of the cover plate 2 so that the pull rod 7 can pass through smoothly. In the middle of the inner peripheral wall of the sampling cylinder 1, a sampling plate 3 is hinged on one side, and a stop block 5 is fixed on the other side. The size and shape of the sampling plate 3 match the cross-section of the inner peripheral wall of the sampling cylinder 1. The pull rod 7 is connected to the connecting piece 6 at the center of the upper surface of the sampling plate 3, and the upper end of the pull rod 7 passes out of the through hole 21 of the cover plate 2. In actual application, the operation process of the ground material sampling device is very simple. First, the sampler needs to rotate the sampling plate 3 to the lowest end by pressing down the pull rod 7 to prepare for sampling (i.e., Figure 3 the state shown). Then, by pressing down the sampling cylinder 1, it is inserted into the ground material to be sampled. During the sampling process, since the sampling cylinder 1 is designed to be airtight, even in an environment with strong wind, it can effectively prevent powder dust from flying, thereby reducing the risk of the sampler inhaling the dust. After sampling, the sampler only needs to hold the sampling cylinder 1 and lift the pull rod 7 upward to lift the sampling plate 3. When the sampling plate 3 abuts against the stop block 5, the upper half chamber of the sampling cylinder 1 is sealed, and the powder is retained in the sealed chamber of the sampling cylinder 1 (i.e., Figure 6 the state shown). At this time, the sampler can take out the sampling cylinder 1 from the ground material to complete the entire sampling process. The advantages of this ground material sampling device are that it only requires one sampler to complete a series of work such as sampling and loading, greatly reducing the labor usage and improving the labor efficiency. At the same time, due to its airtight design, it ensures that the powder will not fly during the sampling process, thus protecting the health of the sampler. In addition, the device has strong applicability. Whether for different types of ground materials or for sampling requirements in different environments, it can be adapted by adjusting the size and shape of the sampling cylinder 1 and the sampling plate 3, making the device have a wide application prospect.

[0025] In an embodiment of the present utility model, as Figure 3 and in combination with Figure 6As shown, the sampling cylinder 1 is formed by precisely welding the front side wall, rear side wall, left side wall and right side wall, forming a stable rectangular cylinder. This structure not only ensures the strength of the sampling cylinder 1 but also its stability in various complex environments. In the middle of the front side wall and the rear side wall, near one end of the left side wall, there is an installation hole respectively. These two installation holes are not only opposite in position but also have the same aperture, ensuring the installation accuracy and stability. Between the installation holes, a rotating shaft 8 is installed. This rotating shaft 8 is one of the core components of the sampling cylinder 1. It bears the movement of the sampling plate 3, enabling it to perform various actions such as sampling, flipping, and receiving. The material of the rotating shaft 8 is usually selected as a high-strength and wear-resistant material to ensure its stability and reliability during use. At the left end of the sampling plate 3, there is a circular curled edge 31. Through the cooperation of the curled edge 31 and the rotating shaft 8, the sampling plate 3 can be stably fixed on the rotating shaft 8. This structure has strong usability and maintainability. Its structure is simple and clear, easy to install and disassemble. At the same time, each component can be replaced and repaired separately, reducing the maintenance cost and time.

[0026] In an embodiment of the present utility model, as Figure 7 shown, the front end of the rotating shaft 8 passes through the front side wall, and the part of the front end of the rotating shaft 8 passing through is pressed into a flat nozzle shape. The rear end of the rotating shaft 8 passes through the rear side wall, and the part of the rear end of the rotating shaft 8 passing through is also pressed into a flat nozzle shape. The parts of the rotating shaft 8 passing through at the front and rear ends both adopt the flat nozzle shape structure. The flat nozzle shape structure can effectively limit the forward and backward movement of the rotating shaft 8, ensuring that the rotating shaft 8 always maintains a stable posture during operation. This setting not only extends the service life of the rotating shaft 8 but also reduces the failure rate of the sampling device, providing a strong guarantee for the stable operation of the entire sampling device. The flat nozzle shape structure makes the cross-sectional shape of the rotating shaft 8 present a flat shape when passing through the side wall. This shape design enables the rotating shaft 8 to form a certain frictional force within the side wall when subjected to external forces, thereby effectively limiting the forward and backward movement of the rotating shaft 8. At the same time, the flat nozzle shape structure also has a certain elasticity, which can absorb and buffer external force impacts to a certain extent, further protecting the rotating shaft 8 from damage. In addition, the design of the flat nozzle shape structure also takes into account the working environment and usage conditions of the rotating shaft 8. In some harsh working environments, the rotating shaft 8 may be affected by various external forces such as vibration and impact. The flat nozzle shape structure can effectively resist the influence of these external forces, ensuring that the rotating shaft 8 can still maintain stable performance in a complex working environment.

[0027] In an embodiment of the present utility model, as Figure 8As shown in the figure, the through hole 21 of the cover plate 2 is a through hole. In the middle of the pull rod 7, a stop pin 72 is cross-welded. The length of the stop pin 72 is less than the length of the through hole and greater than the width of the through hole. In this way, the stop pin 72 can freely penetrate into the through hole 21. When it is necessary to press down the sampling plate 3, the stop pin 72 penetrates into the through hole 21 from the inside, and the sampling plate 3 is pressed down through the pull rod 7; after the sampling is completed, the stop pin 72 penetrates out of the through hole. After slightly rotating the pull rod 7, the stop pin 72 can be locked on the cover plate 2. When the stop pin 72 penetrates out of the through hole and abuts against the cover plate 2, the sampling plate 3 just abuts against the stop block 5, so as to keep the upper half chamber of the sampling cylinder 1 in a sealed state during use, which is convenient for handling. As Figure 3 and Figure 6 shown, a circular pull ring 71 is welded to the lower end of the pull rod 7. The connecting piece 6 is a semi-circular pull ring, and the semi-circular pull ring penetrates into the circular pull ring 71 and is welded to the center of the sampling plate 3. Through the cooperation of the semi-circular pull ring and the circular pull ring 71, a larger operating space can be provided, the restricted angle of the self-rotation of the pull rod 7 can be reduced, and it is convenient for the stop pin 72 to penetrate out of the through hole 21 and lock with the cover plate 2.

[0028] In an embodiment of the present invention, when the sampling plate 3 hangs naturally, its lower end surface can be precisely flush with the lower end surface of the sampling cylinder 1, so that the sampling plate 3 can be easily inserted into the ground material to be sampled, and more powder can be effectively obtained. This setting not only improves the sampling efficiency, but also ensures that the obtained sample is representative and can truly reflect the actual situation of the ground material. During the sampling process, when the sampling plate 3 abuts against the stop block 5, the sampling plate 3 and the sampling cylinder 1 are in a vertical state. At this time, the gap between the sampling plate 3 and the sampling cylinder 1 reaches the minimum, and this setting effectively prevents the powder from leaking out. In addition, in order to facilitate the sampler to perform the lifting and pressing operations (that is, to lift the template 3 upward and press down the sampling plate 3), the upper end of the pull rod 7 is cleverly bent into a handle 73 in the shape of an inverted triangle with one side open. This setting enables the sampler to more easily control the lifting of the sampling plate 3 during the operation, improving the convenience and comfort of the operation. At the same time, the shape of the inverted triangle handle 73 also increases the holding stability, enabling the sampler to more stably control the sampling plate 3 during the operation.
