Description

Technical Field

[0001] The utility model relates to the technical field of soil samplers, in particular to a portable soil sampler. Background Art

[0002] A portable soil sampler is a portable and easy-to-operate device used to collect soil samples for analysis and testing. Existing portable soil samplers usually require users to manually rotate the collection tube to drill into the soil. This operation is time-consuming and labor-intensive, and it is not possible to effectively sample the deep layer of the soil. The sampling depth and speed are limited, which limits the flexibility and efficiency of the sampler in practical applications. Relying on manual operation, the consistency and accuracy of sampling will be affected. Existing portable soil samplers usually require staff to hold or support the operation during use. This operation method easily causes the sampler to be inserted into the ground at an angle, thereby affecting the sampling effect. Due to the incorrect angle at which the sampler is inserted into the soil, the sampling depth may be uneven or unable to reach the required depth, affecting the accuracy and representativeness of the sampling results. This phenomenon is more common in uneven terrain or when the technical level of the staff is not high. Therefore, the current operation method of the portable soil sampler has certain limitations.

[0027] See also Figure 1-5A portable soil sampler comprises a bottom plate 1, a connecting column 2 is arranged on the bottom plate 1, a stud 3 is arranged on the inner thread of the connecting column 2, a collecting tube 4 is arranged at the bottom end of the stud 3, a plurality of soil-breaking teeth 5 are arranged on the bottom surface of the collecting tube 4, a top plate 6 is rotatably arranged on the top end of the stud 3, a motor 7 is arranged on the top surface of the top plate 6 and the output end is fixedly connected to the stud 3, a connecting rod 8 is rotatably arranged on the outer wall of the bottom plate 1, a plurality of groups of connecting rods 8 are fixedly provided with screws 9 at the bottom ends, a plurality of groups of screws 9 are threadedly connected with adjusting rods 10 on the outer walls, a plurality of groups of adjusting rods 10 are provided with circular grooves 11 at the bottom ends, a plurality of groups of rotating balls 12 are rotatably arranged in the plurality of circular grooves 11, a plurality of supporting feet 13 are fixedly arranged at the bottom ends of the plurality of rotating balls 12, and a plurality of groups of ground nails 14 are arranged on the plurality of supporting feet 13.

[0028] In this embodiment, a top box 15 is provided on the top plate 6, and hinge seats 16 are provided on both sides of the top box 15. Abutment blocks 17 are fixedly provided at the bottom ends of the two groups of hinge seats 16. Connecting blocks 18 are hingedly provided on the two groups of hinge seats, and the base abuts on the abutment blocks 17. Armrests 19 are provided on the two groups of connecting blocks 18 to block the connecting blocks through the abutment blocks, so that the two groups of armrests 19 are horizontally parallel, which is convenient for the staff to press the armrests 19 to stabilize the device. When not in use, the armrests 19 are rotated to make them vertical in the longitudinal direction. The two groups of armrests 19 are bundled together with an external connecting rope, which can make the entire device more compact and convenient to carry and store.

[0029] In this embodiment, a plurality of groups of limit rods 20 are provided on the top surface of the base plate 1 and the top ends penetrate the top plate 6 and are slidably connected thereto. The limit rods 20 are slidably connected thereto and the top plate 6 is limited in vertical movement to prevent the top plate 6 from rotating when the motor 7 drives the stud 3 to rotate. This ensures that the top plate 6 always remains in a vertical state during the movement and does not accidentally rotate or tilt, thereby improving the stability of the equipment and the accuracy of operation.

[0030] In this embodiment, a through groove 21 is opened on the side wall of the collection tube 4, and an arc plate 22 is connected to the through groove 21. The arc plate 22 is connected in the through groove 21 by threads. After the sampling is completed, the arc plate 22 is disassembled, and the collected soil is taken out through the through groove 21, which is convenient for cleaning the collection tube 4.

[0031] In this embodiment, a measuring ruler 23 is fixedly provided on the bottom plate 1 and the top end thereof passes through the top plate 6, so that the user can directly observe the measurement result during use, which is convenient and quick, and reduces the extra time and energy consumed in reading the measurement result.

[0032] In this embodiment, the plurality of groups of ground nails 14 are configured as threaded ground nails. Compared with conventional non-threaded ground nails, threaded ground nails have better fixation and stability and can more firmly fix the soil sampler on the ground.

[0033] In this embodiment, the outer walls of the two sets of armrests 19 are both provided with anti-slip covers 24, which can provide additional friction and increase the comfort and stability of the user when holding the armrests.

[0034] In this embodiment, the side walls of the top plate 6 are provided with a plurality of groups of clips 25. When the sampler is not in use, the connecting rod 8 is clipped into the clip 25, which can effectively reduce the space occupied by the equipment, making it more compact and easy to carry, and convenient for users to carry and move when working in the field.

[0035] Embodiment 2:

[0036] In summary, when in use, multiple groups of support feet 13 are fitted to the ground, and multiple groups of ground nails 14 are screwed into the ground to support the sampler. When encountering rugged ground, the adjusting rod 10 is rotated to screw it on the screw rod 9, and then the length between the connecting rod 8 and the adjusting rod 10 is adjusted. The supporting foot 13 can be supported at a suitable location by rotating the ball 12 in the circular groove 11, and the motor 7 is started to drive the stud 3 to rotate, and the stud 3 drives the collection tube 4 to rotate. The stud 3 is threadedly connected to the connecting column 2, so that the stud 3 drives the top plate 6 to slide vertically along the limit rod 20, and the soil is broken by the rotation of the breaking teeth 5. When the motor 7 is working, the worker The operator holds the handrail 19 with both hands and presses down to facilitate the stable operation of the sampler. The soil depth can be observed during operation through the measuring ruler 23. As the collection tube 4 continues to go deeper into the ground, the soil enters the collection tube 4 to achieve soil sampling. The arc plate 22 is connected in the through groove 21 by a thread. After the sampling is completed, the arc plate 22 is disassembled and the collected soil is taken out through the through groove 21. At the same time, it is convenient to clean the collection tube 4. When the sampler is not in use, the connecting rod 8 is clamped in the clamp 25, which can effectively reduce the space occupied by the equipment, making it more compact and easy to carry, and convenient for users to carry and move when working in the field.

[0037] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
