Description

Technical Field

[0001] The utility model relates to the technical field of sampling, and particularly relates to a sampling device for civil engineering raw materials. Background Art

[0002] Civil engineering involves land excavation, infrastructure construction, road paving, bridge construction, and the structure of large buildings, etc. The environment of civil engineering is complex and changeable. For example, soil types, rock distributions, groundwater levels, etc. in geological conditions will have a significant impact on the design and construction of civil engineering. Due to the complexity of the civil engineering environment, it is necessary to take soil samples, etc. from the construction site for physical and chemical property analysis to determine their engineering properties and applicability. These sampling results are crucial for engineering design, the selection of construction plans, and the assurance of project quality.

[0003] However, due to the complex and changeable environment of civil engineering and the diverse sampling contents, when the traditional general sampling device faces relatively hard sampling materials, it may be difficult to sample or even unable to obtain representative samples due to insufficient force application. Content of the Utility Model

[0004] In view of this, the utility model provides a sampling device for civil engineering raw materials, which can enhance the force application ability of the sampling device so that it can effectively deal with hard civil engineering raw materials.

[0005] To solve the above technical problems, the utility model provides a sampling device for civil engineering raw materials, including a sampling cylinder. A support cylinder is slidably connected to the bottom of the sampling cylinder. A bottom plate is fixedly connected to the bottom of the support cylinder. A plurality of anti-slip rings arranged in an array are fixedly connected to the bottom of the bottom plate. A support plate is fixedly connected to the middle of the sampling cylinder. Pressure plates are fixedly connected to both sides of the support plate. Force application grooves are formed in the middle of the pressure plates. Groove openings are formed in both sides of the support cylinder. A plurality of pedals arranged in an array around the central axis of the sampling cylinder are fixedly connected to the cylinder body of the sampling cylinder between the groove openings. The middle parts of the pedals are slidably connected to the adjacent groove openings, significantly enhancing the force application ability of the sampling device so that it can effectively deal with hard civil engineering raw materials.

[0006] A resilience component is arranged between the sampling cylinder and the support cylinder; that is, by providing elastic support, it helps the sampling cylinder to be smoothly pulled out after sampling.

[0007] The resilience component includes a spring sleeved on the middle part of the sampling cylinder; that is, it provides elastic restoring force.

[0008] The resilience component further includes a plurality of protective covers fixedly connected to the top of the support cylinder. A plurality of guiding grooves corresponding to the upper and lower positions of the protective covers are formed in the middle of the support plate; that is, it covers the spring to prevent impurities from entering and guides the movement of the support plate through the guiding grooves.

[0009] The top of the protective cover is fixedly connected to the same limiting ring; that is, it restricts the moving range of the sampling cylinder to prevent it from penetrating too deeply or detaching from the support cylinder.

[0010] The tops of the pedals are all fixedly connected with a plurality of anti-slip pads arranged in an array; that is, it increases the friction on the surface of the pedals and improves the operation safety.

[0011] The top of the sampling cylinder is fixedly connected with a handle; that is, it is convenient for the operator to carry and lift the sampling device.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4, the technical solutions of the embodiments of the present utility model are described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0023] As Figures 1-4 shown: This embodiment provides a sampling device for civil engineering raw materials, including a sampling cylinder 100. The bottom of the sampling cylinder 100 is slidably connected to a support cylinder 101. The bottom of the support cylinder 101 is fixedly connected to a bottom plate, and the bottom of the bottom plate is fixedly connected with a plurality of anti-slip rings arranged in an array. The inner diameter of the support cylinder 101 is equal to the outer diameter of the sampling cylinder 100. A support plate 102 is fixedly connected to the middle of the sampling cylinder 100. Pressure plates 103 are fixedly connected to both sides of the support plate 102. Force application grooves are formed in the middle of the pressure plates 103. Groove openings 104 are formed on both sides of the support cylinder 101. A plurality of pedals 105 arranged in an array around the central axis of the sampling cylinder 100 are fixedly connected to the cylinder body of the sampling cylinder 100 between the groove openings 104. The middle parts of the pedals 105 are slidably connected to the adjacent groove openings 104;

[0024] During sampling, an operator stands on the pedals 105 and applies pressure to the sampling cylinder 100 through the pedals 105 by using his own weight. The sliding of the pedals 105 along the groove openings 104 drives the movement of the sampling cylinder 100. At the same time, the operator's hands apply pressure synchronously through the force application grooves, driving the pressure plates 103 to apply force to the sampling cylinder 100, so that the sampling cylinder 100 gradually penetrates into the civil engineering raw materials, thereby realizing the sampling of the civil engineering raw materials. By applying force jointly by the pressure plates 103 and the pedals 105, it is ensured that the sampling device can effectively cope with harder civil engineering raw materials, significantly enhancing the force application ability of the sampling device, enabling it to effectively cope with hard civil engineering raw materials and obtain samples. When the sampling cylinder 100 contacts the civil engineering raw materials, the anti-slip rings at the bottom can ensure the stability of the sampling device and prevent it from sliding during the force application process.

[0025] The rebound assembly 200 is as Figure 1 、 2 、shown in Figure 3,

[0026] A rebound assembly 200 is arranged between the sampling cylinder 100 and the support cylinder 101. The rebound assembly 200 includes a spring 201 sleeved on the middle of the sampling cylinder 100. The top of the spring 201 is in contact with the bottom of the support plate 102, and the bottom of the spring 201 is in contact with the top of the support cylinder 101. The diameter of the spring 201 is smaller than the outer diameter of the support cylinder 101;

[0027] When facing harder raw materials, it is often difficult to insert and then pull out the sampling device. This device can provide a resilience force through the spring 201 when retrieving samples, helping the sampling cylinder 100 to be smoothly pulled out from the civil engineering raw materials. When the sampling cylinder 100 penetrates deep into the civil engineering raw materials, the sampling cylinder 100 drives the support plate 102 to move downward while the position of the support cylinder 101 remains unchanged. The spring 201 is compressed by the support plate 102 and the support cylinder 101, storing elastic potential energy. After sampling is completed, the operator can release the pressure on the pedal 105 and the pressing plate 103. At this time, the spring 201 returns to its original state, and the generated resilience force acts on the sampling cylinder 100 to help it be pulled out from the civil engineering raw materials.

[0028] The protective cover 202 is as Figure 1 , 2 , shown in Figure 3

[0029] The resilience component 200 further includes a plurality of protective covers 202 fixedly connected to the top of the support cylinder 101. The protective covers 202 are all arc-shaped, and the inner arc surfaces of the protective covers 202 all face the center of the support cylinder 101. A plurality of guide grooves 203 corresponding to the upper and lower positions of the protective covers 202 are provided in the middle of the support plate 102. The inner diameter of the protective cover 202 is larger than the diameter of the spring 201;

[0030] When the protective cover 202 is working, it can protect the spring 201 from external impurities and damage. When the sampling cylinder 100 penetrates deep into the civil engineering raw materials, the protective cover 202 covers the spring 201, preventing civil engineering raw materials or other sundries from entering the inside of the spring 201, ensuring the normal operation of the spring 201 and extending its service life. At the same time, when the sampling cylinder 100 moves up and down, the protective cover 202 can slide along the guide groove 203, which can provide guidance for the support plate 102 and help to guide the movement track of the sampling device, making it more stable and effective.

[0031] The limit ring 204 is as Figure 3 , shown

[0032] The same limit ring 204 is fixedly connected to the top of the protective cover 202;

[0033] The limit ring 204 can effectively prevent the separation of the sampling cylinder 100 from components such as the support cylinder 101 and the protective cover 202. When the sampling cylinder 100 moves to a certain position, the limit ring 204 will contact the top of the support plate 102, preventing the sampling cylinder 100 from continuing to move.

[0034] The anti-slip pad 106 is as Figure 1 , shown

[0035] A plurality of anti-slip pads 106 arranged in an array are fixedly connected to the top of the pedal 105;

[0036] The anti-slip mat 106 can increase the friction on the surface of the pedal 105, improving the safety of the operator during the sampling process. When the operator steps on the pedal 105, the anti-slip mat 106 can prevent the feet from slipping, ensuring that the operator can apply pressure stably.

[0037] The handle 107 is as Figure 1 , 2 shown,

[0038] A handle 107 is fixedly connected to the top of the sampling cylinder 100. A plurality of arc-shaped grooves are provided at the top of the handle 107;

[0039] The handle 107 allows the operator to easily put their fingers into it and hold the handle 107, thereby lifting the entire sampling device, facilitating the handling of the sampling device.

[0040] Working principle:

[0041] The operator places the sampling device on the surface of the civil engineering raw materials. The sampling cylinder is connected to the bottom plate through the support cylinder. The anti-slip ring on the bottom plate ensures the stability of the device. The operator stands on the pedal and applies pressure to the sampling cylinder through their own weight. At the same time, the operator uses both hands to apply additional pressure through the force application grooves on the pressing plate, causing the sampling cylinder to gradually penetrate into the civil engineering raw materials. The sampling cylinder penetrates into the civil engineering raw materials under the pressure of the operator until the required sampling depth is reached. When the sampling cylinder penetrates into the raw materials, the spring is compressed by the support plate and the support cylinder, storing elastic potential energy. After sampling is completed, the pressure on the pedal and the pressing plate is released, and the spring returns to its original state. The generated resilience helps the sampling cylinder to be withdrawn from the civil engineering raw materials. The protective cover covers the spring to prevent impurities from entering and ensures the normal operation of the spring. At the same time, the protective cover slides along the guide groove to provide guidance for the support plate and stabilize the movement trajectory of the sampling device. The limit ring prevents the sampling cylinder from separating from components such as the support cylinder and the protective cover, ensuring that the sampling cylinder stops when it moves to a certain position and preventing excessive penetration. The anti-slip mat increases the friction of the pedal and improves the operation safety. The handle facilitates the operator to carry the sampling device.

[0042] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
