Description

Technical Field

[0001] This utility model belongs to the field of material sampling technology, and more specifically, relates to a material sampling device. Background Technology

[0002] Material sampling devices are widely used in various production, research, and testing fields to extract a certain amount of sample from materials or samples for further analysis and testing. In many industrial and scientific research fields, sampling is a crucial step in ensuring raw material quality, product qualification, environmental monitoring, and experimental analysis. The accuracy of sampling directly affects the representativeness and reliability of test results. For example, in industries such as mining, oilfield exploration, and building materials production, effective sample collection from large-scale material accumulations is often required. In this context, material sampling devices, as automated and efficient equipment, can effectively improve sampling efficiency and accuracy. While traditional manual sampling methods are effective in some small-scale experiments, they have some significant shortcomings in large-scale industrial applications. First, manual sampling is easily affected by factors such as improper human operation and inappropriate sampling location selection, resulting in poor sample representativeness and an inability to accurately reflect the overall properties of the material. Second, manual sampling is inefficient, labor-intensive, and may pose safety hazards. Therefore, traditional sampling methods are difficult to meet the high-efficiency and precise requirements of modern industrial production and research. With the continuous development of automation and intelligent technologies, modern material sampling devices are increasingly adopting mechanized and automated operation methods, which can greatly improve the accuracy and efficiency of sampling. Current material sampling devices mostly employ technologies such as motor drive, spiral conveyor, and drill bit crushing, enabling stable operation in complex environments and automatic completion of sampling tasks. The equipment design also emphasizes ease of operation, quick sample change, and ease of cleaning and maintenance, making it adaptable to various materials and sampling needs.

[0003] Existing sampling devices cannot ensure that samples only enter the storage components without being leaked, making it difficult to guarantee the integrity of the samples. Utility Model Content

[0004] In view of this, the present invention provides a material sampling device that can solve the problem that existing sampling devices cannot ensure that the sample only enters the storage component and is not leaked, thus making it difficult to guarantee the integrity of the sample.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a material sampling device, comprising a sampling tube, a driving assembly, and a sample storage assembly. The sampling tube is composed of several interconnected tube segments, each segment consisting of an inner tube and an outer tube sleeved together. The driving assembly is connected to the end of the sampling tube and is used to drive the sampling tube to rotate and advance. The sample storage assembly is disposed between the sampling tube and the driving assembly and is used to store the collected sample to prevent sample loss when the sampling device moves. The sampling tube and the sample storage assembly are connected through the sampling tube so that the sample collected by the sampling tube directly enters the interior of the sample storage assembly.

[0007] The top of the sampling tube is connected to a drill bit for breaking and cutting the material to be sampled.

[0008] Based on the above technical solution, the material sampling device of this utility model can be further improved as follows:

[0009] The drive assembly consists of a motor, a reducer, and a drive shaft. The motor drives the drive shaft to rotate through the reducer, and the drive shaft is connected to the sampling tube.

[0010] Furthermore, the sample storage component is movably connected to the sampling tube via a slot and a snap fastener, which facilitates the removal and replacement of the sample.

[0011] Furthermore, a spiral blade is provided between the inner tube and the outer tube of the sampling tube, and the spiral blade is fixedly connected to the inner tube for transporting the collected sample.

[0012] Furthermore, the drive shaft is equipped with a universal joint, which connects the sampling tube and the drive shaft, enabling the sampling tube to sample at different angles, thereby improving sampling efficiency and flexibility.

[0013] Furthermore, a one-way valve is provided at the connection between the sample storage component and the sampling tube, with its movable end facing the interior of the sample storage component, to prevent the loss of samples that have entered the sample storage component.

[0014] Furthermore, the sample storage assembly has threads on its sidewall, which are threaded to the sampling tube.

[0015] Furthermore, the outer tube of the sampling tube is provided with several positioning holes, which are used to install auxiliary devices.

[0016] Furthermore, the auxiliary device includes a camera and a lighting fixture for observing the sampling process and the surrounding environment.

[0017] Furthermore, the inner tube is made of high-strength alloy steel, and the outer tube is made of wear-resistant engineering plastic.

[0018] Compared with the prior art, the beneficial effects of the material sampling device provided by this utility model are:

[0019] The sampling tube consists of several interconnected sections, each composed of an inner and an outer tube. This design makes the sampling tube scalable and flexible, easily adapting to sampling needs at different depths. The inner and outer tube structure ensures that materials will not leak during sampling and enhances the durability and damage resistance of the tube sections.

[0020] A helical blade is installed between the inner and outer tubes, and the helical blade is fixedly connected to the inner tube for transporting the collected sample. This design allows the sample collected during the sampling process to be transported to the sample storage component via the rotating helical blade, thereby improving the efficiency of sample transport and ensuring that the sample is not lost due to long-term storage.

[0021] The drive assembly consists of a motor, a reducer, and a drive shaft. The motor drives the drive shaft to rotate via the reducer, which in turn rotates and advances the sampling tube. The combination of the motor and reducer provides stable and adjustable power output to adapt to sampling needs in different environments. The drive shaft connects to the sampling tube, ensuring that power is transmitted to the tube, causing it to rotate and advance to the target position.

[0022] A universal joint is installed on the drive shaft, allowing the sampling tube to take samples at different angles. This design enhances the equipment's adaptability to complex environments, enabling sampling from multiple angles and improving sampling flexibility and efficiency.

[0023] The sample storage component, located between the sampling tube and the drive assembly, stores the collected samples. This component ensures that the collected samples are not lost during the movement of the sampling device. Through a through-connection with the sampling tube, the sample storage component allows the collected samples to directly enter the storage component, ensuring sample integrity.

[0024] The sample storage component and sampling tube are movably connected via slots and snap-fit ​​mechanisms, facilitating sample retrieval and replacement. This design enhances operational convenience and flexibility, making sample extraction and replacement more efficient while reducing operational complexity.

[0025] The sample storage assembly has threads on its sidewalls, which connect to the sampling tube to ensure a stable connection and facilitate installation and disassembly.

[0026] The sampling tube is connected to a drill bit at its tip for breaking and cutting the material to be sampled. The drill bit can effectively handle materials of varying hardness, ensuring smooth access to the sampling area and successful sample collection. Its design optimizes the sampling device's ability to work with hard materials.

[0027] A one-way valve is installed at the connection between the sample storage component and the sampling tube. The movable end of this valve faces inward towards the sample storage component to prevent sample loss once it enters the component. The one-way valve design ensures that the sample only enters the storage component and is not leaked out, thus guaranteeing sample integrity.

[0028] Several positioning holes on the outer tube of the sampling tube are used to install auxiliary devices. Auxiliary devices such as cameras and lights can provide real-time monitoring and observation functions, helping operators to check the sampling process and environmental changes, thereby optimizing the sampling operation, especially in low-light or complex environments.

[0029] The inner tube is made of high-strength alloy steel, while the outer tube is made of wear-resistant engineering plastic. The inner tube material ensures the durability and corrosion resistance of the sampling tube, enabling it to adapt to harsh working environments; the wear-resistant properties of the outer tube material enhance its service life and reduce performance degradation caused by wear.

[0035] like Figure 1The illustration shows an embodiment of a material sampling device provided by this utility model. In this embodiment, it includes a sampling tube 10, a driving component 20, and a sample storage component 30. The sampling tube 10 is composed of several interconnected tube segments, each of which is formed by an inner tube and an outer tube sleeved together. The driving component 20 is connected to the end of the sampling tube 10 and is used to drive the sampling tube 10 to rotate and advance. The sample storage component 30 is disposed between the sampling tube 10 and the driving component 20 and is used to store the collected sample to prevent the sample from being lost when the sampling device moves. The sampling tube 10 and the sample storage component 30 are connected in a through connection so that the sample collected by the sampling tube 10 can directly enter the interior of the sample storage component 30.

[0036] The top of the sampling tube 10 is connected to a drill bit for crushing and cutting the material to be sampled.

[0037] In the above technical solution, the drive component 20 consists of a motor, a reducer and a transmission shaft. The motor drives the transmission shaft to rotate through the reducer, and the transmission shaft is connected to the sampling tube 10.

[0038] Furthermore, in the above technical solution, the sample storage component 30 and the sampling tube 10 are movably connected by a slot and a snap fastener, which facilitates the removal and replacement of the sample.

[0039] Furthermore, in the above technical solution, a spiral blade is provided between the inner tube and the outer tube of the sampling tube 10. The spiral blade is fixedly connected to the inner tube and is used to transport the collected sample.

[0040] Furthermore, in the above technical solution, a universal joint is provided on the drive shaft, which connects the sampling tube 10 and the drive shaft, enabling the sampling tube 10 to perform sampling at different angles, thereby improving sampling efficiency and flexibility.

[0041] Furthermore, in the above technical solution, a one-way valve is provided at the connection between the sample storage component 30 and the sampling tube 10, with its movable end facing the inside of the sample storage component 30, in order to prevent the loss of samples that have entered the sample storage component 30.

[0042] Furthermore, in the above technical solution, the sample storage component 30 is provided with threads on its side wall and is connected to the sampling tube 10 by threads.

[0043] Furthermore, in the above technical solution, the outer tube of the sampling tube 10 is provided with several positioning holes, which are used to install auxiliary devices.

[0044] Furthermore, in the above technical solution, the auxiliary device includes a camera and a lighting lamp, used to observe the sampling process and the surrounding environment.

[0045] Furthermore, in the above technical solution, the inner tube material is high-strength alloy steel, and the outer tube material is wear-resistant engineering plastic.

[0046] Specifically, the principle of this utility model is as follows: Before use, first check whether all components of the sampling device are intact, ensuring that the motor, drive shaft, spiral blades, sample storage components, etc., are not damaged or loose. Select the appropriate sampling tube length according to actual needs and install it into the device. Ensure the sampling tube connection is stable and the sample storage components are in place. Set the motor speed and sampling angle according to the depth and type of the sampling target. The settings of the drive components can be adjusted to ensure the device can adapt to sampling requirements of different materials and depths. Start the motor and control its speed through the reducer. The motor speed determines the rotation and advance speed of the sampling tube. For initial use, the speed can be set to a lower rate to ensure smooth operation. Ensure the sampling tube can enter the sampling area; if necessary, use a universal joint to adjust the angle so that the sampling tube can adapt to different sampling environments.

[0047] Once the equipment starts operating, the motor drives the drive shaft to rotate, which in turn moves the sampling tube and helical blades to collect material samples. The drill bit breaks the target material and transports the sample through the helical blades to the sample storage assembly. The sampling process is monitored by auxiliary devices (such as cameras and lighting) to ensure smooth sampling and prevent sample leakage or loss. After sampling is complete, the motor is turned off, stopping the drive shaft. Once the equipment has come to a complete stop, the sample storage assembly is opened, and the collected sample is retrieved. The sample in the storage assembly is checked for integrity, ensuring no loss. If multiple samplings are required, the storage assembly can be cleaned and prepared for the next sampling cycle. After use, the sampling device is cleaned, especially the sampling tube and sample storage assembly, to remove any residue. Components such as the helical blades, internal and external tubing, and one-way valves are regularly inspected for wear or damage. The drill bit's sharpness is also regularly checked to ensure it can effectively break materials. If the drill bit is severely worn, it should be replaced promptly.
