[0026] Embodiment

[0027] As Figures 1-3 shown, a surface layer soil sampling device proposed in an embodiment of the present utility model includes an installation shell 1. A connecting rod 2 is fixedly connected to the top of the installation shell 1. A hand rod 3 is fixedly connected to the top of the connecting rod 2. A counterweight box 4 is fixedly connected to the left side of the installation shell 1. A battery 5 is fixedly connected to the right side of the installation shell 1. A motor 6 on one side of the installation shell 1 is fixedly connected above the battery 5. The output end of the motor 6 penetrates the installation shell 1 and is fixedly connected to a driving gear 7. An auxiliary gear disk 8 is meshed and driven on the driving gear 7. The center of the auxiliary gear disk 8 is coaxially rotatably connected to an active bevel gear disk 9. The active bevel gear disk 9 is meshed and driven with an auxiliary bevel gear disk 10. A transmission shaft 11 is fixedly connected to the center of the auxiliary bevel gear disk 10. An installation groove 12 is opened at the bottom end of the transmission shaft 11. A rotating rod 13 is inserted into the interior of the installation groove 12. A nut 15 is sleeved on the rotating rod 13. The nut 15 is threadedly connected to the bottom of the installation shell 1. There are spiral blades on the rotating rod 13. A drill bit 16 is fixedly connected to the bottom of the rotating rod 13;

[0028] The device mainly consists of an installation shell 1, a connecting rod 2, a hand rod 3, a counterweight box 4, a battery 5, a motor 6, a transmission system, a rotating rod 13, a drill bit 16, etc. The installation shell 1, as the core component, connects and carries various functional components. The connecting rod 2 connects the installation shell 1 to the hand rod 3, facilitating the operation of the user. The counterweight box 4 is located on the left side of the installation shell 1, and the battery 5 and the motor 6 are located on the right side of the installation shell 1. This layout balances the weight of the device to a certain extent, ensuring stability during use.

[0029] The motor 6 serves as the power source, and its output end passes through the installation shell 1 and then connects to the driving gear 7. After the motor 6 is started, the driving gear 7 drives the auxiliary gear disk 8 to rotate.

[0030] The center of the auxiliary gear disk 8 is coaxially rotatably connected to the driving bevel gear disk 9, and the rotation of the auxiliary gear disk 8 drives the driving bevel gear disk 9 to rotate. The driving bevel gear disk 9 is also meshed with the auxiliary bevel gear disk 10 for transmission. Through this multi-stage transmission method, the power of the motor 6 is transmitted to the auxiliary bevel gear disk 10.

[0031] The center of the auxiliary bevel gear disk 10 is fixedly connected to the transmission shaft 11. The bottom end of the transmission shaft 11 is provided with a hexagonal bolt-shaped installation groove 12 for inserting the rotating rod 13. This connection method enables the power to be effectively transmitted to the rotating rod 13, and at the same time facilitates the installation and disassembly of the rotating rod 13.

[0032] A nut 15 is sleeved on the rotating rod 13, and the nut 15 is threadedly connected to the bottom of the installation shell 1, playing a role in fixing and limiting the rotating rod 13. The rotating rod 13 is provided with spiral blades. When the rotating rod 13 rotates, the spiral blades can transport the soil upward to achieve the function of soil sampling.

[0033] A retaining piece is provided at one place on the rotating rod 13 to prevent the nut 15 from slipping out when rotating on the rotating rod 13, ensuring the stable position of the nut 15, and thus guaranteeing the stability of the rotating rod 13 during operation.

[0034] The bottom of the rotating rod 13 is fixedly connected to the drill bit 16. The function of the drill bit 16 is to facilitate the insertion of the device into the soil. The sharp drill bit 16 can reduce the resistance when inserting into the soil and improve the sampling efficiency.

[0035] The working principle is as follows:

[0036] When soil sampling is required, start the motor 6. The rotation of the motor 6 drives the driving gear 7 connected to its output end to rotate. The driving gear 7 is meshed with the auxiliary gear disk 8 for transmission, causing the auxiliary gear disk 8 to start rotating.

[0037] Since the center of the auxiliary gear disk 8 is coaxially rotatably connected to the driving bevel gear disk 9, the rotation of the auxiliary gear disk 8 drives the driving bevel gear disk 9 to rotate. The driving bevel gear disk 9 is also meshed with the auxiliary bevel gear disk 10 for transmission, transmitting the power to the auxiliary bevel gear disk 10.

[0038] The transmission shaft 11 fixedly connected to the center of the auxiliary bevel gear disc 10 rotates accordingly. The installation groove 12 at the bottom end of the transmission shaft 11 is in the shape of a hexagonal bolt and is adaptively inserted into the top of the rotating rod 13, thereby driving the rotating rod 13 to rotate.

[0039] During the rotation of the spiral blade on the rotating rod 13, it cuts into the soil like a spiral drill bit 16. As the rotating rod 13 continuously rotates, the spiral blade continuously conveys the soil upward.

[0040] At the same time, the drill bit 16 at the bottom of the rotating rod 13 is more likely to be inserted into the soil under the action of rotation and downward pressure, reducing the insertion resistance.

[0041] In the whole device, the counterweight box 4 on the left side of the installation shell 1 is internally provided with counterweight blocks for balancing the weights of the motor 6 and the battery 5 to ensure the stability of the device during operation. At the same time, the battery 5 is rechargeable and supplies power to the motor 6. The nut 15 sleeved on the rotating rod 13 is threadedly connected to the bottom of the installation shell 1 to fix and limit the rotating rod 13, and the stop piece on the rotating rod 13 prevents the nut 15 from slipping out.

[0042] As Figure 2 shown, in some embodiments, the counterweight box 4 is internally provided with counterweight blocks for balancing the weights of the motor 6 and the battery 5; ensuring that the device remains balanced during use and improving the accuracy and stability of sampling.

[0043] As Figure 2 shown, in some embodiments, the drive gear 7, the auxiliary gear disc 8 and the driving bevel gear disc 9 are rotatably arranged inside the installation shell 1; First of all, it plays a protective role. The installation shell 1 provides a relatively enclosed space for these gears and gear discs, which can prevent external dust, sundries, etc. from entering the transmission system, avoid damage to the transmission components, and ensure the accuracy and reliability of the transmission.

[0044] Secondly, it is beneficial to maintain the integrity and stability of the device. Placing the transmission components inside the installation shell 1 makes the whole device structure more compact, reduces the possible shaking or misalignment caused by the exposure of the components, and can better maintain stable operation during operation.

[0045] Finally, it improves safety. Storing these transmission components in the installation shell 1 can reduce the risk that the operator is accidentally injured by the rotating components during use.

[0046] As Figure 3As shown, in some embodiments, a bearing 14 is sleeved and rotated on the surface of the transmission shaft 11, and the bearing 14 is fixedly installed inside the mounting shell 1; on the one hand, the bearing 14 provides stable support for the transmission shaft 11. During the process of power transmission, the transmission shaft 11 will bear large torque and radial forces. The bearing 14 can effectively disperse these forces, prevent the transmission shaft 11 from bending or deforming, and ensure that the transmission shaft 11 can rotate stably.

[0047] On the other hand, the bearing 14 reduces the rotational resistance of the transmission shaft 11. Since the balls or rollers inside the bearing 14 can roll, the frictional force when the transmission shaft 11 rotates is greatly reduced, improving the transmission efficiency, reducing energy loss, and at the same time extending the service life of the transmission shaft 11 and the entire device.

[0048] In addition, fixedly installing the bearing 14 inside the mounting shell 1 ensures the stable position of the bearing 14, further enhancing the structural stability and reliability of the entire device.

[0049] As Figure 3 shown, in some embodiments, the shape of the mounting groove 12 is hexagonal bolt-shaped and is adapted to the top of the rotating rod 13; this shape of the mounting groove 12 ensures a firm connection between the rotating rod 13 and the transmission shaft 11. The hexagonal bolt-shaped mounting groove 12 fits tightly with the top of the rotating rod 13. During the operation of the device, it can effectively transmit power, prevent the rotating rod 13 from loosening or slipping, and ensure the stability and reliability of the sampling process.

[0050] As Figure 3 shown, in some embodiments, a retaining piece is provided at one place on the rotating rod 13, and the nut 15 is rotated on the rotating rod 13 and is blocked by the retaining piece and will not slide out for limiting; the retaining piece can effectively prevent the nut 15 from sliding out of the rotating rod 13. During the operation of the device, the rotating rod 13 rotates at a high speed. Without the limitation of the retaining piece, the nut 15 may loosen and slide out due to factors such as centrifugal force, resulting in an unstable position of the rotating rod 13 and affecting the soil sampling effect. With the blocking of the retaining piece, the nut 15 is firmly restricted within a certain range, ensuring the stability of the rotating rod 13 during operation.

[0051] On the other hand, this limiting design is also convenient for installation and disassembly. When the rotating rod 13 needs to be replaced or repaired, the rotating rod 13 can be quickly fixed or loosened through the cooperation of the nut 15 and the retaining piece, improving the operation convenience. At the same time, it also ensures the safety of the device during use and avoids safety accidents caused by the accidental sliding out of the nut 15.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
