[0031] Reference Figure 1-6 ,

[0032] A soil sampler anti-pinch structure includes: a soil sampler body 1, a push rod 2, and a cutting ring 3. The soil sampler body 1 is a hollow rod-shaped structure. The cutting ring 3 is provided at one end of the soil sampler body 1, and a first gripping part 11 is formed at the other end of the soil sampler body 1. The first gripping part 11 is a hollow rod-shaped structure. The soil sampler body 1 forms an installation chamber 12. The push rod 2 is disposed within the installation chamber 12, with one end extending into the cutting ring 3 forming a pushing part 21, and the other end forming a second gripping part 22, which is located outside the soil sampler body 1. The second gripping part 22 is a hollow rod-shaped structure. During use, the operator holds the first grip 11 with their hand, ensuring the center line of the cutting ring 3 is perpendicular to the ground. The operator then applies pressure to the ground to insert the cutting ring 3 into the soil. Next, the operator pulls out the portion of the cutting ring 3 that is inserted into the soil and uses the second grip 22 to push the push rod 2 towards the cutting ring 3, causing the pushing part 21 on the push rod 2 to push the soil out of the cutting ring 3. An anti-pinch structure is located within the installation chamber 12. This structure creates an anti-pinch gap between the first grip 11 and the second grip 22 to prevent the operator's hand from colliding with the first grip 11.

[0033] Specifically, the anti-pinch structure includes a spring 4 and a stop block 5. A bearing surface 121 is formed inside the mounting chamber 12, and the centerline of the soil sampler body 1 is perpendicular to the bearing surface 121. The stop block 5 is disposed on the push rod 2, and the outer wall surface of the stop block 5 contacts the inner wall surface of the mounting chamber 12. An abutment surface 51 is formed on the stop block 5. The spring 4 is disposed between the bearing surface 121 and the abutment surface 51. When the hand holds the second grip 22 and pushes the push rod 2 toward the cutting ring 3, the human body often has difficulty controlling the pushing force, resulting in the hand colliding with the soil sampler body 1. Therefore, in this embodiment, a spring 4 and a stop block 5 are provided. During the process of the hand holding the second grip 22 and pushing the push rod 2 toward the cutting ring 3, the stop block 5 can abut against the spring 4, and the spring 4 can play a certain buffering role to prevent the push rod 2 from being pushed too far, thereby avoiding the hand colliding with the soil sampler body 1.

[0034] Specifically, a foot pedal 6 is installed on the main body 1 of the soil sampler. The center line of the foot pedal 6 is perpendicular to the center line of the main body 1 of the soil sampler. The foot pedal 6 is designed to provide a foothold for the human body, so that the worker can apply pushing force towards the ground.

[0035] Specifically, the foot pedal 6 is connected to the soil sampler body 1 via a mounting sleeve 7 and a bolt 8. The mounting sleeve 7 is located on the outer wall of the soil sampler body 1 and is slidably connected to it. One end of the foot pedal 6 is fixedly connected to the mounting sleeve 7. A threaded hole 71 is formed on the mounting sleeve 7. The bolt 8 is threadedly connected to the threaded hole 71. The end of the bolt 8 inserted into the threaded hole 71 abuts against the outer wall of the soil sampler body 1. The slidable connection between the mounting sleeve 7 and the soil sampler body 1 allows the position of the foot pedal 6 on the soil sampler body 1 to be adjustable, accommodating different operators' habits. The bolt 8 can fix the adjusted mounting sleeve 7 to the outer wall of the soil sampler body 1, facilitating timely adjustments by operators and simplifying operation.

[0036] Specifically, an installation groove 72 is formed within the mounting sleeve 7. A rubber washer 73 is installed within the mounting groove 72. The inner wall of the rubber washer 73 contacts the outer wall of the soil sampler body 1, and one end of the bolt 8 inserted into the threaded hole 71 abuts against the outer wall of the rubber washer 73. The rubber washer 73 is provided to enhance the friction between the mounting sleeve 7 and the soil sampler body 1, preventing the foot pedal 6 from sliding on the soil sampler body 1 when the worker's foot applies pressure.

[0037] Specifically, a limiting part 61 is formed at the end of the foot pedal 6 opposite to the mounting sleeve 7. The limiting part 61 is inclined relative to the center line of the foot pedal 6 towards the end opposite to the cutting ring 3. The limiting part 61 is a block structure. The limiting part 61 is used to prevent the foot from slipping off the foot pedal 6 when the worker's foot applies pressure to the foot pedal 6, providing a certain degree of safety.

[0038] Specifically, dust covers 9 are provided at both ends of the mounting sleeve 7. The dust covers 9 are fixedly connected to the mounting sleeve 7. When the worker's feet are placed on the foot pedal 6, some dust on the soles of the shoes may fall between the mounting sleeve 7 and the soil sampler body 1, causing the mounting sleeve 7 to be unable to slide on the soil sampler body 1. Therefore, in this embodiment, dust covers 9 are provided at both ends of the mounting sleeve 7 to avoid this problem.

[0039] Specifically, when the contact surface 51 contacts the spring 4, a gap is formed between the first gripping part 11 and the second gripping part 22, and the pushing part 21 is located outside the cutting ring 3, so as to ensure that when the pushing part 21 completely pushes the soil out of the cutting ring 3, the hand still maintains a safe distance from the soil extractor body 1, so as to prevent injury to the hand.

[0040] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
