Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and in particular relates to a soil sample collection device that facilitates sampling. Background Technology

[0002] Soil sampling plays a crucial role in environmental monitoring, agricultural science, geological research, and ecology. With increasing attention to soil quality, particularly regarding environmental protection and sustainable development, precise and efficient soil sampling methods and technologies have rapidly developed. Traditional soil sampling tools are mostly manual, such as augers and shovels. These tools are simple and inexpensive, but inefficient, labor-intensive, and struggle to guarantee the accuracy and representativeness of the samples. With advancements in mechanization and automation, various types of automatic or semi-automatic soil sampling equipment have emerged, such as auger-based samplers and hydraulically driven deep soil sampling systems. While these devices improve sampling speed and accuracy to some extent, they are poorly adaptable to complex terrains and are typically bulky, difficult to transport, and unsuitable for single-person operation.

[0003] The shortcomings of existing technologies are mainly reflected in several aspects: First, most existing equipment lacks good mobility and flexibility; second, the structural design of traditional sampling devices is often not compact enough, making it inconvenient to fine-tune the sampling position. Therefore, we propose a soil sample collection device that is convenient for sampling. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a soil sample collection device that facilitates sampling. It features a rotatable disc with a sampling device mounted on it, allowing for easy fine-tuning of the sampling position.

[0005] This utility model is implemented as follows: a soil sample collection device for convenient sampling includes a mobile trolley. Two columns are fixedly connected to the upper part of the mobile trolley. A top plate is fixedly connected to the top of each column. A lifting plate is slidably connected to each column. A screw is rotatably connected to the top plate via a bearing. The lower part of the screw is connected to the lifting plate via a thread. A mounting frame is fixedly connected to one side of the lifting plate. A mounting plate is welded to the lower part of the mounting frame. A reduction motor is connected to the lower part of the mounting plate. A turntable is fixedly connected to the lower end of the output shaft of the reduction motor. A second motor is fixedly connected to the upper outer edge of the turntable. A sampling cylinder is fixedly connected to the lower end of the output shaft of the second motor. The lower part of the sampling cylinder is provided with cutting teeth.

[0006] Optionally, a handle is fixedly connected to the upper part of the screw, and a limit plate is fixedly connected to the lower end of the screw.

[0007] Optionally, a limit frame is installed on the lifting plate, the limit frame including a fixed rod, the fixed rod being welded to the lifting plate, and two smooth plates being welded on the fixed rod.

[0008] Optionally, the upper and lower outer edges of the turntable are respectively provided with lubricating oil storage grooves, and the middle part of the turntable is provided with a groove.

[0009] Optionally, the mobile trolley is equipped with wheels, and a handrail is welded to one side of the mobile trolley.

[0010] Optionally, an air pump is fixedly connected to the lifting plate, a hose is connected to the air outlet of the air pump, and a hose interface is connected to the sampling tube.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: By incorporating a rotatable turntable into the soil sample collection device and mounting a sampling device on it, the function of fine-tuning the sampling position is achieved. This design not only improves the operational flexibility of the equipment but also significantly enhances the accuracy and efficiency of sampling. Specifically, by using a geared motor to drive the turntable to rotate, which in turn drives a second motor fixed on it and a sampling cylinder connected to the lower end of its output shaft, a small-range horizontal movement can be achieved solely through motor control without changing the height of the lifting plate, thereby accurately locating the ideal sampling point. This feature is particularly important for studies that require obtaining samples from multiple different locations at the same site, ensuring that each sampling accurately reaches the predetermined position and avoiding the inconvenience of repeatedly adjusting the entire device position.

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] like Figures 1 to 5 As shown in the figure, this utility model provides a soil sample collection device that facilitates sampling.

[0020] The device includes a mobile trolley 2, with two columns 5 fixedly connected to the upper part of the mobile trolley 2. A top plate 4 is fixedly connected to the top of the columns 5, and a lifting plate 6 is slidably connected to the columns 5. A screw 10 is rotatably connected to the top plate 4 via a bearing. The lower part of the screw 10 is connected to the lifting plate 6 via a thread. A mounting frame 14 is fixedly connected to one side of the lifting plate 6. A mounting plate 15 is welded to the lower part of the mounting frame 14. A reduction motor 16 is connected to the lower part of the mounting plate 15. A turntable 7 is fixedly connected to the lower end of the output shaft of the reduction motor 16. A second motor 8 is fixedly connected to the upper part of the outer edge of the turntable 7. A sampling cylinder 9 is fixedly connected to the lower end of the output shaft of the second motor 8. The lower part of the sampling cylinder 9 is provided with cutting teeth 91.

[0021] A handle 20 is fixedly connected to the upper part of the screw 10, and a limit plate is fixedly connected to the lower end of the screw 10.

[0022] A limit frame 11 is installed on the lifting plate 6. The limit frame 11 includes a fixing rod 112, which is welded to the lifting plate 6. Two smooth plates 111 are welded on the fixing rod 112.

[0023] The upper and lower outer edges of the turntable 7 are respectively provided with lubricating oil storage grooves 18, and the middle part of the turntable 7 is provided with a groove 17.

[0024] The mobile cart 2 is equipped with wheels 1, and a handrail 3 is welded to one side of the mobile cart 2.

[0025] An air pump 13 is fixedly connected to the lifting plate 6. A hose 12 is connected to the air outlet of the air pump 13, and a hose interface 19 is connected to the sampling tube 9.

[0026] Working principle: First, the operator pushes the mobile cart 2 to the target sampling location using the handle 3. The mobile cart 2 is equipped with wheels 1, which allows it to move easily on various terrains, ensuring that the equipment can reach any location where sampling is required.

[0027] Once the designated position is reached, the operator uses handle 20 to rotate screw 10. Since screw 10 and lifting plate 6 are connected via a threaded drive, the lifting plate 6 slides up and down along column 5 when handle 20 is rotated. This process allows the operator to precisely adjust the entry depth of sampling tube 9 according to actual needs, thus ensuring the representativeness of the sample.

[0028] Mounting bracket 14 is fixed to one side of lifting plate 6 and has mounting plate 15 welded to it, ultimately connecting to geared motor 16. Geared motor 16 drives turntable 7 to rotate. A second motor 8 is located on the upper outer edge of turntable 7, with its output shaft fixedly connected to sampling cylinder 9. When fine-tuning of the sampling position is required, geared motor 16 drives turntable 7 to rotate, allowing sampling cylinder 9 to achieve precise positioning within a small range in the horizontal direction. This design is particularly suitable for situations where multiple samples from different locations need to be obtained at the same location.

[0029] To ensure the smooth operation of the turntable 7 and reduce frictional resistance, lubricating oil storage grooves 18 are opened on the upper and lower sides of its outer edge. These grooves are filled with an appropriate amount of lubricating oil, which effectively reduces the friction generated when the turntable 7 rotates, while maintaining good lubrication of mechanical parts and extending service life.

[0030] Once the sampling tube 9 reaches the predetermined position, the second motor 8 starts, driving the sampling tube 9 and its bottom cutting teeth 91 to rotate and cut into the soil, completing sample collection. After sampling, the air pump 13 is connected to the hose interface 19 on the sampling tube 9 through the hose 12, using air pressure to push the sample out of the sampling tube 9, simplifying the subsequent processing and collection procedures.

[0031] Finally, the limiting frame 11 on the lifting plate 6, including the fixing rod 112 and the smooth plate 111, ensures that the turntable 7 remains stable during rotation, prevents unnecessary shaking, and improves the reliability and safety of the entire system.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
