When in use, the staff steps on the positioning pedal 7 with both feet, the positioning pedal 7 moves downward, and the positioning rod 701 is inserted into the soil, so as to realize the positioning of the sampler and avoid displacement during the sampling process. After the sampling is completed, the staff leaves the positioning pedal 7, and the positioning pedal 7 can drive the positioning rod 701 to automatically move up and separate from the soil, and the sampler can be in a free moving state.
[0047] The working principle of this embodiment:
[0048] First, the operator can easily move the entire sampler to the desired sampling location by holding the handle 201 on the top frame 2. At this time, the universal wheel 101 at the bottom of the sampling frame 1 plays a key role, making the movement and positioning of the sampler easy and comfortable. After arriving at the sampling location, the operator steps on the positioning pedal 7 to insert the positioning rod 701 into the soil. The tip structure of the positioning rod 701 helps it to be smoothly inserted into the soil, and the retaining ring 702 ensures that the positioning rod 701 will not completely pass through the sampling frame 1. When the positioning rod 701 is inserted into the soil, the spring 703 is compressed. When the operator leaves the positioning pedal 7 When the sampler is moved upward, the elastic force of the spring 703 will automatically move the positioning rod 701 upward and separate from the soil, thereby facilitating the movement of the sampler. After the positioning is completed, the operator turns the hand wheel 302 to make the screw rod 301 in the lifting adjustment seat 3 move upward and downward. Since the lower end of the screw rod 301 is rotatably engaged with the upper end of the sampling drive seat 4, the lifting and lowering movement of the screw rod 301 will drive the sampling drive seat 4 to move upward and downward along the slide rail 102. During this process, the sliding of the slider 401 on the slide rail 102 ensures that the lifting and lowering movement of the sampling drive seat 4 is smooth and accurate. When the sampling drive seat 4 drops to a suitable position, the sampling motor 402 starts to work. The reducer shaft is driven to rotate, thereby driving the spiral sampling screw 404 to rotate. The lower end of the sampling screw 404 is a drill bit 40401, which drills into the soil while rotating to bring the soil sample into the sampling screw 404. In the sampling process, the ruler 403 plays a key role. By observing the scale on the ruler 403, the operator can accurately grasp the drilling depth of the sampling screw 404, thereby achieving multi-point sampling and maintaining a consistent sampling depth. This design helps to improve the accuracy of soil sampling and provides reliable data support for subsequent soil analysis. At the same time, the guide seat 5 and the guide sleeve 501 The setting ensures that the sampling spiral 404 can maintain a stable motion trajectory when drilling into the soil, avoiding deviation and shaking, and the excavation guide tube 502 guides the soil sample taken out from the sampling spiral 404, and introduces it into the collection area between the sample soil receiving sleepers 6 through the sample soil receiving tube 601, so as to facilitate subsequent collection and processing. After the sampling is completed, the operator only needs to stop the operation of the sampling motor 402 through the control button 202, and raise the sampling drive seat 4 to the initial position by turning the hand wheel 302, and then step on the positioning pedal 7 to make the positioning rod 701 separate from the soil, and then the sampler can be moved to the next sampling point or other operations can be performed.
