Description

Technical Field

[0001] The utility model relates to the technical field of greening projects, in particular to a soil collector for greening projects. Background Art

[0002] In the process of ecological restoration through garden engineering, it is often necessary to improve the soil quality through soil improvement. While eliminating soil pollution, the soil quality should be repaired and improved to lay the foundation for subsequent greening projects. Before soil improvement, it is necessary to sample, test and analyze the soil, and then plan a soil improvement plan.

[0003] Utility model patent CN220231016U discloses a greening project collector, including a base, a fixed plate, a lifting mechanism, a connecting mechanism, a collecting tube, a collecting head, and a fixed assembly. The middle of the base is fixedly connected to the fixed plate, and the top of the base is fixedly connected to the lifting mechanism for collecting soil from greening projects. The collecting tube and the collecting head are connected by a connecting mechanism below the lifting mechanism for collecting through the lifting mechanism, and the collecting tube passes through the fixed assembly in the middle of the fixed plate.

[0004] The utility model avoids the quality of the sampled samples from being affected by contamination between samples due to multiple sampling by designing the collection tube as a detachable structure. However, when the device collects soil, the collection tube is directly driven to move vertically downward by the lifting mechanism. When encountering hard soil, the simple vertical downward movement cannot pierce the soil at all. At the same time, there is no structure on the base to fix it on the ground. When the collection tube moves downward, there is no stable structure to fix it, and the collection effect is poor. Utility Model Content

The top of the push-pull rod 7 passes upward through the sampling tube 5 and the pressing plate 4 and is slidably connected thereto. The lower end of the sampling tube is threadedly connected to an earth-breaking drill bit 8;

[0021] By driving the sampling tube 5 to rotate through the driving structure 6 and cooperating with the earth-breaking drill bit 8, the collection work of soils with different hardnesses can be dealt with, the collection effect can be improved. At the same time, a positioning structure 2 is arranged on the base 1 to increase the stability during collection. And the arrangement of the push-pull rod 7 facilitates the pushing out of the soil sample after sampling, the sampling is convenient and fast, and the practicability is high.

[0022] In another embodiment, please refer to Figure 1-2 , the positioning structure 2 includes a vertically arranged threaded rod 21. The lower end of the threaded rod 21 passes through the base 1 and is threadedly connected thereto. A spiral fixing rod 22 is arranged at one end of the threaded rod 21 located below the base 1.
