Description

Technical Field

[0001] This utility model relates to the field of soil sampling devices, and more particularly to a peat soil sampling device. Background Technology

[0002] Peat soil is an organic soil formed by the long-term decomposition and accumulation of plant residues in waterlogged and oxygen-deficient environments. It plays an important role in agriculture, horticulture and other fields. The organic matter content of peat soil usually exceeds 30%, and can even reach more than 70%. Its organic carbon, humic acid and other components can be accurately measured by sampling.

[0003] In traditional mining operations, during the collection process, the upper soil layers are often inadvertently collected along with the soil sample to a specified depth. This is detrimental to soil research and interferes with accurate analysis of soil structure and composition. Furthermore, to collect soil at a specific depth, a drill bit must first be used to reach the predetermined depth, and then a specially designed collection device must be used to insert the sample into the pre-drilled hole. Only in this way can mineral or resource collection be effectively carried out, ensuring the accuracy and representativeness of the sample. However, this method is not conducive to soil research, and the sample may be subject to secondary contamination during the collection process. The complex process consumes more time and manpower, reduces mining efficiency, and increases mining costs.

[0004] In view of this, the present invention is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a peat soil sampling device in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A peat soil sampling device includes a support for inserting and fixing peat, and a drill bit for drilling into the peat. The drill bit includes a conical shell for collecting peat. A compression mechanism is provided inside the conical shell. The compression mechanism includes a straight rod assembly mounted on the inner wall of the conical shell. The straight rod assembly includes a connecting rod. Crossbars are symmetrically mounted on both sides of the connecting rod. A disc for assisting stretching is fixedly connected to the top of the connecting rod. A sleeve rod assembly slides on the surface of the straight rod assembly. The sleeve rod assembly includes a sleeve that slides on the surface of the connecting rod. A turntable for rotating the device is mounted on the surface of the sleeve. A collection mechanism is provided at the top of the conical shell. The collection mechanism includes an outer shell for soil sampling. A sliding sleeve is installed on the inner wall of the outer shell. The sliding sleeve is movably connected to the outer wall of the sleeve. A tension spring for pulling up the sleeve is installed at the bottom of the disc.

[0007] Preferably, the surface of the conical shell is fitted with threaded cutting tools for drilling into the soil.

[0008] Preferably, the bottom of the connecting rod is mounted on the inner wall of the conical shell.

[0009] Preferably, the sleeve has two symmetrically opened sliding grooves for sliding limit of the crossbar on its surface, and a first pin is symmetrically installed on the surface of the sleeve.

[0010] Preferably, a second pin is installed on the bottom outer wall of the sliding sleeve, and a support rod is installed between the first pin and the second pin. A top cover is installed on the top of the outer shell to prevent external soil from falling into the conical shell and internal soil from leaking. The sliding sleeve slides on the surface of the crossbar.

[0011] Preferably, one end of the sleeve is movably fitted with a retaining strip for restricting the movement of the tension spring.

[0012] Preferably, the bottom of the tension spring is mounted on the surface of the sleeve, and the connecting rod passes through the tension spring.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: During equipment operation, the tip of the support is first inserted into the soil. Then, the turntable is rotated to allow the threaded blades on the drill bit to penetrate the soil. As the drill bit penetrates deeper, when the predetermined depth is reached, the retaining bar is released, and the tension spring begins to retract. Under the force of the retracting spring, the sleeve slowly rises. Subsequently, the outer shells on both sides slowly open. The turntable is then slowly rotated to allow the outer shells to slowly collect the soil, thus effectively collecting the soil. After the collection process is completed, the retaining bar is retracted, and the soil is collected inside the conical shell. The entire collection process is simple and convenient, greatly improving mining efficiency.

[0014] When the drill bit reaches the predetermined depth, the chuck is disengaged, and the tension spring causes the sleeve to rise slowly. During this process, two sliding sleeves, which are movably connected to the sleeve, move in opposite directions along the crossbar. The movement of the sliding sleeves, in turn, causes the outer shell to gradually open. Then, by slowly rotating the disc, the outer shell collects the surrounding soil. After soil collection is complete, the tension spring is pressed downwards, and the sliding sleeves guide the outer shell to slowly retract. The collected soil falls into the conical shell. Finally, by rotating the disc in the opposite direction, the equipment can be removed. The entire collection process avoids secondary pollution and ensures that soil at the specified depth can be accurately collected, providing convenience for research work.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 - Figure 4 As shown, the present invention provides a peat soil sampling device, including a bracket 10 inserted and fixed into the soil, and a drill bit 20 for drilling into the soil. The drill bit 20 includes a conical shell 22 for collecting soil. A compression mechanism 30 is provided inside the conical shell 22. The compression mechanism 30 includes a straight rod assembly 31 installed on the inner wall of the conical shell 22. The straight rod assembly 31 includes a connecting rod 311. Crossbars 312 are symmetrically installed on both sides of the connecting rod 311. A disc 31 for assisting in stretching is fixedly connected to the top of the connecting rod 311. 3. A sleeve rod assembly 32 slides on the surface of the straight rod assembly 31. The sleeve rod assembly 32 includes a sleeve 321 that slides on the surface of the connecting rod 311. A turntable 322 for rotating the device is installed on the surface of the sleeve 321. A collection mechanism 40 is provided at the top of the conical shell 22. The collection mechanism 40 includes a housing 41 for soil sampling. A sliding sleeve 42 is installed on the inner wall of the housing 41. The sliding sleeve 42 is movably connected to the outer wall of the sleeve 321. A tension spring 323 for pulling up the sleeve 321 is installed at the bottom of the disc 313.

[0018] The device is equipped with a support 10 that is inserted into and fixed in the soil, providing stable support for the entire device. This ensures that the drill bit 20 remains stable during drilling into the soil, guaranteeing a stable and reliable sampling process and preventing inaccurate sampling due to device shaking. The drill bit 20 includes a conical shell 22 for collecting soil. The conical design makes it easier for the drill bit 20 to drill into peat soil and effectively collect soil, improving sampling efficiency. The collection mechanism 40 at the top of the conical shell 22 is equipped with an outer shell 41 for soil sampling. Its inner wall sliding sleeve 42 is movably connected to the outer wall of the sleeve 321, allowing the collection mechanism to cooperate with the compression mechanism, making the entire sampling process more convenient and seamless.

[0019] Specifically, such as Figure 2 As shown, the surface of the conical shell 22 is fitted with threaded cutting tools 21 for drilling into the soil.

[0020] The threaded blades 21 mounted on the surface of the conical shell 22 for drilling into the soil can improve the device's ability and efficiency in drilling into the soil. The threaded blades 21 utilize their unique thread structure to more easily form a soil debris discharge channel during the drilling process, reducing drilling resistance. Compared with the smooth surface of the conical shell, they can cut into the soil more effectively, enabling the device to enter the land more quickly and stably, improving work efficiency and ease of operation.

[0021] Specifically, such as Figure 2 As shown, the bottom of the connecting rod 311 is mounted on the inner wall of the conical shell 22.

[0022] By precisely installing the connecting rod 311 on the inner wall of the conical shell 22, it is ensured that the drill bit 20 can rotate simultaneously with the rotating turntable 322.

[0023] Specifically, such as Figure 2 As shown, the surface of the sleeve 321 is symmetrically provided with two sliding grooves 324 for sliding limit of the crossbar 312, and the surface of the sleeve 321 is symmetrically provided with a first pin 325.

[0024] The two grooves 324 on the surface of the sleeve 321 provide precise sliding limits for the crossbar 312, effectively preventing the crossbar 312 from deviating or wobbling during sliding, ensuring the accuracy and stability of operation. The first pin 325 symmetrically installed on the surface of the sleeve 321 can provide a flexible connection method to realize the rotation or hinge of the mechanism.

[0025] Specifically, such as Figure 2 As shown, a second pin 44 is installed on the bottom outer wall of the sliding sleeve 42, and a support rod 43 is installed between the first pin 325 and the second pin 44. A top cover 45 is installed on the top of the outer shell 41 to prevent external soil from falling into the conical shell 22 and internal soil from leaking. The sliding sleeve 42 slides on the surface of the crossbar 312.

[0026] A second pin 44 is installed on the bottom outer wall of the sliding sleeve 42, and a support rod 43 is installed together with the first pin 325 to form a stable connection between the components, so that the device can work together. At the same time, a top cover 45 is installed on the top of the outer shell 41, which can effectively prevent external soil from falling into the conical shell 22 and internal soil from leaking, and avoid shallow soil and other impurities from affecting subsequent research.

[0027] Specifically, such as Figure 2 As shown, a retaining strip 50 for restricting the movement of the tension spring 323 is movably installed at one end of the sleeve 321.

[0028] One end of the sleeve 321 is provided with a movable retaining strip 50, which can effectively limit the movement of the tension spring 323 and improve its working stability and effectiveness.

[0029] Specifically, such as Figure 2 As shown, the bottom of the tension spring 323 is mounted on the surface of the sleeve 321, and the connecting rod 311 passes through the tension spring 323.

[0030] The combination of tension spring 323, sleeve 321, and connecting rod 311 allows tension spring 323 to control the movement of connecting rod 311 using its own elastic properties. Through the through-type connection, it can effectively transmit force and ensure the flexibility and stability of mechanical movements.

[0031] In use, the tip of the support 10 is inserted into the soil, and then the drill bit 20 is placed in the area to be excavated. The rotary table 322 is then rotated, and the drill bit 20 slowly penetrates the soil. When the predetermined depth is reached, the retaining strip 50 is released. Under the tension of the tension spring 323, the sleeve 321 is slowly pulled up, simultaneously causing the first pin 325 on the sleeve 321 to move. As the first pin 325 rises, it also drives the support rod 43 to move. The support rod 43 then pushes the sliding sleeve 42 outwards, while the sliding sleeve 42 slowly pushes the outer shell 41, causing the outer sides to... The shell 41 opens slowly, and then the turntable 322 rotates slowly. The opened shell 41 slowly collects the surrounding soil. When the collection is finished, the turntable 322 is pressed down, and the sleeve 321 will descend. At the same time, the sliding sleeves 42 on both sides slowly retract under the action of the support rod 43, which drives the shell 41 to close slowly. Finally, the collected soil will enter the conical shell 22. Then the turntable 322 is rotated in the opposite direction to remove the device from the soil. This device realizes convenient insertion and positioning, and the drilling depth is controllable. At the same time, different numbers of soil samples can be collected according to the specific needs of the research.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
