Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling drills, in particular to a self-locking electric soil sampling drill. Background Art

[0002] At present, the traditional soil sampling drills that are widely used have some unsatisfactory aspects: The manual soil sampling drill has poor soil sampling effect, is very laborious, and has extremely low work efficiency; The electric soil sampling drill has unreliable work, poor safety, low precision, high operation cost, and requires a large amount of financial resources; Both have inconvenient operation and unreliable self-use, bringing trouble to the operation and reducing the usage frequency. The traditional soil sampling drill also has the following several disadvantages and deficiencies: First, for plots with complex soil conditions, the soil sampling effect is very poor. Second, for very dense soil, it is very difficult for manual labor to take soil. Third, in alpine regions, it is impossible for manual labor to take soil from frozen soil. Fourth, for soil with high humidity and high viscosity, the soil sampling precision is very low. Fifth, during operation, the electric soil sampling drill is not safe and reliable, and for a large number of operations, it will cause a great waste of human, material and financial resources.

[0003] In summary, when the existing soil sampling drill samples soil with relatively severe soil compaction, the soil sampling drill cannot penetrate the surface layer of the soil, thus seriously affecting the soil sampling effect and further resulting in a low work efficiency. Content of the Utility Model

[0005] A self-locking electric soil sampling drill of the utility model comprises a driving motor 1, a storage battery 2, a support frame 3, a forward and reverse switch 4, a cycloidal pinwheel speed reducer 5, a coupling 6, a drill handle 7 and a soil sampling unit;

[0006] The driving motor 1 is arranged at the center of the upper surface of the support frame 3, the storage battery 2 is arranged at one end of the upper surface of the support frame 3, and the storage battery 2 is used for supplying power to the driving motor 1. The cycloidal pinwheel speed reducer 5 is arranged at the center of the lower surface of the support frame 3. After the output end of the driving motor 1 passes through the support frame 3, it is connected to the power input end of the cycloidal pinwheel speed reducer 5. The power output end of the cycloidal pinwheel speed reducer 5 is connected to the top end of the drill handle 7 through the coupling 6. The bottom end of the drill handle 7 is integrally welded and fixed to the soil sampling unit. The forward and reverse switch 4 is arranged on the side surface of the support frame 3;

[0016] Further, during use, the operator holds the annular handles at both ends of the support frame 3 with both hands and presses the forward rotation switch in the forward and reverse switch 4 on the support frame 3, thereby starting the drive motor 1. Since a cycloidal pinwheel speed reducer 5 is provided at the center of the lower surface of the support frame 3, and after the output end of the drive motor 1 passes through the support frame 3, it is connected to the power input end of the cycloidal pinwheel speed reducer 5. The power output end of the cycloidal pinwheel speed reducer 5 is connected to the top end of the drill shank 7 through a coupling 6.

At this time, the switch is turned off, the drive motor 1 is braked, the soil sampling unit is pulled out of the bottom surface, and the soil sample in the soil sampling cavity 12 of the soil sampling bucket 8 is taken out, thus completing the soil sampling. Using an electric soil drill with this structure is time-saving and labor-saving, simple to operate, can cope with soil with severe hardening for sampling, thereby ensuring the soil sampling effect and improving the working efficiency of soil sampling.

The power output end of the cycloidal pinwheel speed reducer is connected to the top end of the drill shank through a coupling. Then, the drive motor drives the soil sampling unit at the bottom end of the drill shank to rotate. The cycloidal pinwheel speed reducer is used to achieve self-locking of the soil sampling unit to ensure safety and reliability, and precise transmission greatly improves the soil sampling accuracy. Additionally, a plurality of serrated cutter blocks are evenly arranged on the opening end face of the soil sampling bucket in the soil sampling unit, and a plurality of cutter grooves are evenly machined on the outer surface of the bottom of the soil sampling bucket along the circumferential direction.

[0033] Working Principle

[0034] During use, the operator holds the annular handles at both ends of the support frame 3 with both hands and presses the forward rotation switch in the forward and reverse switch 4 on the support frame 3, so as to start the drive motor 1. Since a cycloidal pinwheel speed reducer 5 is provided at the center of the lower surface of the support frame 3, and after the output end of the drive motor 1 passes through the support frame 3, it is connected to the power input end of the cycloidal pinwheel speed reducer 5. The power output end of the cycloidal pinwheel speed reducer 5 is connected to the top end of the drill handle 7 through a coupling 6. Furthermore, the soil sampling unit at the bottom end of the drill handle 7 is driven to rotate by the drive motor 1. Among them, the cycloidal pinwheel speed reducer 5 is used to achieve self-locking and limit of the soil sampling unit; combined with the fact that a plurality of serrated knife blocks 11 are evenly provided on the opening end surface of the soil drill bucket 8 in the soil sampling unit, and a plurality of knife grooves are evenly machined on the outer surface of the bottom of the soil drill bucket 8 along the circumferential direction, and a blade 10 is embedded in each knife groove. When sampling soil with a relatively severe soil compaction, the serrated knife blocks 11 and the blades 10 on the bottom surface of the soil drill bucket 8 can quickly break the soil compaction layer on the soil surface. After the operator applies a pressure perpendicular to the bottom surface to this device, the soil drill bucket 8 will continuously move downward until the soil sampling cavity 12 in the soil drill bucket 8 is filled with soil. At this time, the switch is turned off, the drive motor 1 is braked, the soil sampling unit is pulled out of the bottom surface, and the soil sample in the soil sampling cavity 12 of the soil drill bucket 8 is taken out, thereby completing the soil sampling; using an electric soil drill with such a structure is relatively time-saving and labor-saving, and the operation is simple. It can cope with soil with relatively severe soil compaction for sampling, thereby ensuring the soil sampling effect and further improving the working efficiency of soil sampling.
