In the description of the embodiments of the invention, it also should explain that unless otherwise clearly defined and limited, the terms “provided”, “installed”, “connected” and other terms should be interpreted broadly; for example, it can be a fixed connection, it can be a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirectly connection through an intermediate medium, and it can be an internal communication between two elements or the interaction relationship between two elements.

In combination with the FIG. 1 to FIG. 3, a pole hole soil sampler, comprising a support frame 1 and a spoon body 2. In this embodiment, both the support frame 1 and the spoon body 2 are made of metal materials.

The support frame 1 has a U-shaped structure, specifically, the support frame 1 comprises a fixed plate 11 and connecting rods 12 connected to both ends of the fixed plate 11. During implementation, the support frame 1 enables the installation of the spoon body 2 inside it.

Further, through holes 7 are provided on one end of the connecting rods 12 away from the shovel plate 13. By setting the through holes 7, it is possible to achieve a fixed connection between the support frame 1 and the rod body, extending the length of use of the soil sampler;

During specific implementation, placing the end of the long rod body at the position between the connecting rods 12 and the support frame 1, and connecting it to the long rod body through the through holes 7 with screws to achieve a fixed connection between the support frame 1 and the long rod body.

A shovel plate 13 is provided on an upper part of the fixed plate 11 along the length direction. Specifically, the shovel plate 13 is folded towards the side away from the connecting rods 12, and there is a certain angle between the shovel plate 13 and the fixed plate 11. The angle between the shovel plate 13 and the fixed plate 11 is set according to the actual situation to facilitate the excavation of soil in the hole by the soil sampler.

The spoon body 2 is rotatably provided inside the support frame 1, and the specific structure of the spoon body 2 can be set according to the actual situation. In the embodiment of the invention, the spoon body 2 is a hollow structure with an open upper end, and the cross-section of the spoon body 2 is triangular.

In the embodiment of the invention, by the cooperation of the support frame 1 with the spoon body 2, a cofferdam can be formed for the spoon body 2 through the fixed plate 11 and the connecting rods 12 in the support frame 1, which can prevent soil from falling out of the spoon body 2 due to arm shaking, effectively improving the construction efficiency of the pole hole and reducing labor intensity.

During implementation, through the cooperation between the spoon body 2 and the support frame 1, the excavation of soil in the hole is achieved. At the same time, due to the rotational cooperation between the spoon body 2 and the support frame 1, when excavating the hole wall, the spoon body 2 can move towards an inner side of the support frame 1 under the push of the hole wall, making it convenient for the shovel plate 13 to excavate the hole wall.

Connecting pieces 3 are provided in a middle of the front end of the spoon body 2; connecting holes 4 that cooperate with the connecting pieces 3 are provided in a middle lower part of the fixed plate 11. During implementation, by the active cooperation between the connecting pieces 3 and the connecting holes 4, the rotational cooperation between the spoon body 2 and the fixed plate 11 can be ensured, thereby achieving the rotational setting of the spoon body 2 on the inner side of the support frame 1.

Springs 5 are provided at a bottom of the spoon body 2, and two ends of the springs 5 extend to the outside of the spoon body 2 and are connected to the connecting rods 12. Specifically, the spring 5 is a flexible rod-shaped structure as a whole. The springs 5 are provided along the bottom of the spoon body 2, and two ends of the springs 5 extend to the outside of the spoon body 2 and are respectively connected to the corresponding connecting rods 12. Through the setting of the springs 5, the relative position of the spoon body 2 in the support frame 1 can be stabilized, and the spoon body 2 can be reset during use.

Specifically, hook holes 6 are provided on connecting rods 12; ends of springs 5 matched with the hook holes 6 to ensure the firmness of the connection between the end of the springs 5 and the connecting rods 12.

During implementation, by connecting the springs 5 with the spoon body 2 and the connecting rods 12, the stability of the relative position of the spoon body 2 inside the support frame 1 can be ensured. When using the soil sampler to excavate the hole wall inside the hole, the spoon body 2 moves towards the inner side of the support frame 1 under the push of the hole wall, making it convenient for the shovel plate 13 to excavate the hole wall. After excavation is completed, the spoon body 2 can be restored to its initial position under the action of the springs 5.

During the implementation of the invention, before use, a suitable long pole body can be selected according to the depth of the pole hole to be excavated, and the fixed connection between the support frame 1 and the long pole body can be achieved through the setting of the through holes 7, extending the length of the soil sampler and facilitating the excavation of soil inside the pole hole.

During use, when excavating the soil inside the pole hole, the shovel plate 13 on the fixed plate 11 is used to excavate the soil, and the spoon body 2 provided in the support frame 1 is used to store the excavated soil, in order to excavate the soil inside the pole hole.

The invention and the embodiments thereof are described hereinabove, and this description is not restrictive. What is shown in the drawings is only one of the embodiments of the invention, and the actual structure is not limited thereto. In summary, structural methods and embodiments similar to the technical solution without departing from the inventive purpose of the invention made by inspired ordinary technicians in the art without creative efforts shall all fall within the protection scope of the invention.
