[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 A portable soil and rock sampler for exploration includes a sampling cylinder 1, a push plate 2, and a stepping mechanism. The push plate 2 is slidably connected inside the sampling cylinder 1 via a pushing mechanism, enabling it to push out the soil and rock inside the sampling cylinder 1. The stepping mechanism is installed on the sampling cylinder 1, allowing the operator to press the sampling cylinder 1 down into the soil and rock. Through the cooperation between the sampling cylinder 1, the push plate 2, the pushing mechanism, and the stepping mechanism, when sampling soil and rock, the operator can step down on the sampling cylinder 1 to insert it into the soil and rock. When pulling out the sampling cylinder 1, the operator can press down on the push rod 3 to drive the push plate 2 to push out the soil and rock inside the sampling cylinder 1, thereby achieving rapid soil and rock sampling. No positioning pins are required during use, which saves time and effort and improves the convenience of the sampler.

[0023] The pushing mechanism includes a push rod 3 and a support assembly. The push rod 3 is square in shape, and a square hole is provided on the sampling cylinder 1. The push rod 3 is slidably connected to the square hole. A fixed shaft 8 is fixedly connected to the top of the push rod 3, and handles 9 are fixedly connected to both ends of the fixed shaft 8. The push rod 3 is fixedly connected to the top of the push plate 2. The support assembly is provided on the push rod 3 to support the push plate 2. The support assembly includes a support plate 4 and a spring 5. The support plate 4 is fixedly connected to the push rod 3, and the two ends of the spring 5 are respectively connected to the support plate 4 and the sampling cylinder 1. The sample tube 1 is fixedly connected, and the spring 5 is sleeved on the circumferential surface of the push rod 3. After the sample tube 1 is inserted into the rock and soil, the operator pulls the push rod 3 upward, thereby pulling the sample tube 1 out of the rock and soil. At this time, the sample tube 1 carries out the rock and soil. Then, the sample tube 1 is placed on the ground, and the operator uses his foot to step on the support plate 4 to drive the push rod 3 and the push plate 2 to move downward inside the sample tube 1, thereby pushing out the rock and soil inside the sample tube 1. Then, the operator releases the support plate 4, and the spring 5 pushes the push rod 3 back to its original position.

[0024] The stepping mechanism includes a stepping pedal 6 and insert teeth 7. The stepping pedal 6 is fixedly connected to the top of the sampling cylinder 1. There are multiple insert teeth 7, which are circular and located at the bottom of the sampling cylinder 1. When sampling the soil and rock, the operator steps down on the stepping pedal 6 with his foot, thereby driving the insert teeth 7 at the bottom of the sampling cylinder 1 to insert into the soil and rock for sampling.

[0025] Working principle: When sampling soil and rock, the operator places the sampling tube 1 at the desired sampling location and steps down on the pedal 6, causing the insertion teeth 7 at the bottom of the sampling tube 1 to insert into the soil and rock for sampling. After the sampling tube 1 is inserted into the soil and rock, the operator pulls the push rod 3 upward, causing the push plate 2 and the sampling tube 1 to be pulled out of the soil and rock. At this time, a large amount of soil and rock remains in the sampling tube 1. Then, the sampling tube 1 is placed on the ground, and the operator steps down on the support plate 4, causing the push rod 3 and the push plate 2 to move downward inside the sampling tube 1, thereby pushing out the soil and rock inside the sampling tube 1. Afterward, the operator releases the support plate 4, and the spring 5 pushes the push rod 3 back to its original position, allowing for continued sampling.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
