Description
Technical Field
[0001] This utility model relates to the field of geological exploration technology, specifically to a soil stratification and extraction device for albic soil. Background Technology
[0002] In fields such as geological exploration, stratified sampling and analysis of albic soil is an important prerequisite for obtaining soil characteristics and making scientific decisions. In geological exploration, stratified sampling data of albic soil plays a key role in analyzing stratigraphic structure, geological evolution process, and potential geological hazard risks. Albic soil has a unique soil structure and physicochemical properties, and its different soil layers have significant differences in indicators such as nutrient content, microbial distribution, and water content. Accurate stratified sampling can provide detailed and reliable evidence for geological structure research and resource exploration.
[0003] However, existing soil sampling devices have many problems when performing stratified sampling of albic soil in geological exploration. On the one hand, most devices struggle to achieve precise stratified sampling, and the sampling process can easily lead to mixing of different soil layers, affecting the accuracy and validity of the sampling data and thus interfering with the scientific validity of the geological exploration results. On the other hand, traditional soil sampling devices have low sampling efficiency and are cumbersome to operate, requiring significant manpower and time costs in complex geological environments, making it difficult to meet the needs of rapid geological exploration operations. In addition, some devices are not convenient to remove soil after sampling, increasing the complexity of the sampling work and affecting the overall progress of the exploration work. These problems seriously restrict the efficient implementation of stratified sampling of albic soil in geological exploration, and there is an urgent need for a soil sampling device suitable for geological exploration scenarios that can accurately stratify, efficiently sample, and conveniently remove soil to meet practical application needs. Utility Model Content
[0004] The purpose of this invention is to provide a soil stratification sampling device for albic soil, in order to solve the problems mentioned in the background art, such as the difficulty in accurately sampling in layers, low sampling efficiency, and inconvenience in soil collection, which cannot meet the needs of efficient albic soil stratification sampling in geological exploration.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered soil sampling device for albic soil, comprising a base, a top frame fixedly installed at the upper end of the base, a lifting motor fixedly installed on the upper surface of the top frame, a displacement rod fixedly connected to the lower end of the output shaft of the lifting motor, a sliding rod fixedly connected between the base and the top frame, a lifting frame provided on the outer surface of the displacement rod and the sliding rod, a controller fixedly installed on the upper surface of the lifting frame, a rotating central rod installed in the center of the outer surface of the lifting frame, a drill rod fixedly connected to the lower end of the central rod, a drill bit fixedly installed at the lower end of the drill rod, a spiral blade fixedly installed on the outer surface of the drill rod, a central gear fixedly installed on the outer surface of the central rod, an active motor fixedly installed on the upper surface of one end of the lifting frame, and an active gear fixedly connected to the lower end of the output shaft of the active motor;
[0006] The lower end of the drill rod has a pressure chamber, and a sliding scraper is installed inside the pressure chamber. The drill rod has a pressure groove, and a piston rod is installed at the upper end of the pressure groove. A mounting plate is fixedly installed on the upper surface of the piston rod, and a rotating contact wheel is installed at the upper end of the mounting plate. An electric push rod is fixedly installed on the upper surface of the lifting frame, and a compression ring is fixedly installed at the lower end of the electric push rod.
[0007] Preferably, the displacement rod and the lifting frame are threadedly connected, and the lifting frame and the sliding rod are slidably connected.
[0008] By adopting the above technical solution, when the displacement rod is driven to rotate by the lifting motor, the lifting frame can be moved vertically along the sliding rod by means of the threaded engagement. The guiding effect of the sliding rod can ensure that the drill rod and drill bit accurately cut into the target soil layer, thereby achieving depth control of layered sampling.
[0009] Preferably, the central gear meshes with the driving gear, and the central gear is concentrically arranged with the central rod.
[0010] Using the above technical solution, the active motor drives the active gear to mesh with the central gear, which can stably drive the central rod and drill rod to rotate. The concentric design of the central gear and the central rod can prevent the drill rod from shaking when rotating and prevent soil from mixing between different soil layers.
[0011] Preferably, the pressure chamber and the scraper are connected by sliding friction, and a spring is connected between the scraper and the pressure chamber. One end of the scraper penetrates the outer surface of the drill rod, and one side of the outer surface of the scraper is concave.
[0012] Using the above technical solution, the sliding fit and spring connection between the pressure chamber and the scraper plate can automatically reset the scraper plate after soil extraction. One end of the scraper plate passes through the drill rod and its outer surface is concave, which facilitates the scraping and storage of soil samples when it extends out of the drill rod, thus preventing the samples from falling off.
[0013] Preferably, the lower end of the pressure groove penetrates the inner surface of the pressure chamber, and the upper end of the pressure groove penetrates the upper surface of the drill rod. The pressure groove and the piston rod are connected by sliding friction, and a spring is connected between the piston rod and the drill rod.
[0014] Using the above technical solution, the pressure groove connects the pressure chamber and the upper surface of the drill rod. When the piston rod slides in the pressure groove, it can pressurize the pressure chamber and push the scraper to extend and extract soil. The spring connection can reset the piston rod after extracting soil, ensuring the reusability of the structure.
[0015] Preferably, the different extrusion rings have different diameters, and the inner and outer surfaces of adjacent extrusion rings are in contact with each other, and the different contact wheels are located below extrusion rings of different diameters.
[0016] Using the above technical solution, extrusion rings of different diameters are set up with corresponding contact wheels. When the electric push rod drives the extrusion rings to press down, they can extrude contact wheels at different positions, causing the piston rod at the corresponding depth to push the scraper to collect soil samples from each layer, thus achieving precise soil sampling in layers.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the white clay soil stratification and extraction device:
[0018] 1. Through the threaded engagement of the lifting motor and the displacement rod, precise displacement control of the lifting frame can be achieved. Combined with the guiding effect of the sliding rod, the drill rod and drill bit can accurately cut into different soil layers at a preset depth. The meshing transmission structure of the central gear and the drive gear ensures stable rotational power of the drill rod and avoids soil layer mixing caused by shaking during sampling. This ensures the independence and accuracy of soil samples from each layer, providing scientific and reliable stratification data for geological exploration.
[0019] 2. The spiral blades are fixed to the outside of the drill rod. When the drill rod rotates, the cut soil can be transported upward simultaneously, reducing the soil accumulation resistance in the hole. Combined with the efficient soil breaking design of the drill bit, the sampling efficiency is significantly improved. Compared with traditional devices, this structure can greatly shorten the sampling time per hole. Especially in complex geological environments in the field, it can effectively reduce manpower input and operation time, meeting the needs of rapid geological exploration.
[0020] 3. The pressure chamber and scraper structure inside the drill rod, through the linkage design of spring reset and piston rod, when the electric push rod drives the squeezing ring to press down the contact wheel, the piston rod can push the scraper to extend and collect soil samples, avoiding the cumbersome operation of traditional manual soil collection, ensuring that the soil collection process is convenient and efficient, reducing the risk of sample contamination, and improving the overall progress of exploration work.

[0032] The central gear 12 is meshed with the driving gear 14, and the central gear 12 is concentrically arranged with the central rod 8;
[0033] The controller 7 starts the lifting motor 3 to drive the displacement rod 4 to rotate. Through the threaded engagement, the lifting frame 6 moves vertically between the base 1 and the top frame 2 along the sliding rod 5. The sliding rod 5 guides and ensures that the drill rod 9 and the drill bit 10 accurately cut into the target soil layer. The active motor 13 drives the active gear 14 to mesh with the central gear 12, driving the central rod 8 and the drill rod 9 to rotate at a uniform speed. The central gear 12 and the central rod 8 are concentrically set to avoid the drill rod 9 shaking and causing soil mixing. When the drill rod 9 rotates, the outer spiral blades 11 transport the cut soil upwards to reduce the accumulation resistance in the hole. The drill bit 10 is installed at the lower end of the drill rod 9. Its structural design can efficiently break up the white clay soil. Together with the spiral blades 11, it improves the sampling efficiency.
[0034] Example 2: This example discloses the following based on Example 1: A pressure chamber 15 is provided inside the lower end of the drill rod 9, and a sliding scraper 16 is installed inside the pressure chamber 15.

An mounting plate 19 is fixedly provided on the upper surface of the piston rod 18, and a rotating contact wheel 20 is installed at the upper end of the mounting plate 19. An electric push rod 22 is fixedly installed on the upper surface of the lifting frame 6, and an extrusion ring 21 is fixedly installed at the lower end of the electric push rod 22.
