Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil sampler. Background Technology

[0002] Against the backdrop of increasing global awareness of ecological and environmental protection and the in-depth promotion of the strategy of sustainable agricultural development, the quality status is related to food security and environmental quality. Soil samplers have become an urgent need in the fields of agriculture, environmental protection and geology for monitoring the fertility of arable land and assessing the remediation of polluted soil.

[0003] In the prior art, some soil samplers typically consist of a handle, a connecting rod, a sampling tube, and a sample collection device. By holding the handle and applying pressure, the connecting rod drives the sampling tube to cut into the soil. The hollow structure of the sampling tube grabs a portion of the soil sample, which is then poured out and collected into the sample collection device. This allows for the collection of soil samples from different soil layers for analysis of soil composition.

[0004] In some existing soil samplers, the sampling tube is difficult to disassemble quickly during practical application. The time loss and cumbersome operation caused by the inconvenience of disassembling the sampling tube restrict the progress of soil sampling. Therefore, a soil sampler is proposed to solve the above problems. Utility Model Content

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.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a soil sampler, including a handle 1 and a mounting base 3. The handle 1 facilitates stable force application by the operator, and the mounting base 3 provides a mounting foundation for the sampling cylinder 6. A disassembly mechanism 2 is fixedly connected inside the handle 1, and a soil loosening mechanism 4 is fixedly connected inside the mounting base 3. The disassembly mechanism 2 includes a connecting rod 21, which connects the handle 1 and a connecting rod 23. The connecting rod 21 is externally fixedly connected to the inside of the handle 1, and a spring a22 is sleeved on the outside of the connecting rod 21. The spring a22 provides elastic restoring force, which can drive the connecting rod 23 back to its initial position, realizing the reset of the mechanism. The bottom end of the spring a22 is fixedly connected to the connecting rod 23, which receives... The force from the connecting rod 21 is further transmitted to the internal push rod 24. The push rod 24 is fixedly connected to the bottom inner side of the connecting rod 23. The push rod 24 is used to undertake the axial pushing action and convert the force transmitted from the connecting rod 23 into the axial thrust on the connecting column 25. The bottom of the push rod 24 is fixedly connected to the connecting column 25. The connecting column 25 mainly plays the role of force convergence and redistribution. Two springs b26 are fixedly connected to the outside of the connecting column 25. The springs b26 are used to provide elastic support and reset power for the limiting column 27. The limiting column 27 is fixedly connected to the opposite side of the springs b26. The limiting column 27 mainly plays the role of locking and unlocking the mechanism. The sliding component 28 is fixedly connected to the outside of the connecting column 25.

[0034] The sliding assembly 28 includes a sliding ring 281, which provides guidance and support for the axial movement of the connecting column 25. The inside of the sliding ring 281 is fixedly connected to the outside of the connecting column 25. A sliding ball 282 is fixedly connected to the bottom of the connecting column 25. The sliding ball 282 plays a role in auxiliary guidance, support and reducing friction.

[0035] Reference Figures 1 to 3The soil loosening mechanism 4 includes a cylinder 41, which serves as a power source and provides power for the lifting and lowering of the connecting plate 42. The cylinder 41 is externally fixedly connected to the bottom inner side of the mounting base 3. The driving end of the cylinder 41 is fixedly connected to the connecting plate 42, which transmits the power of the cylinder 41 to the rotating shaft 45 and the support base 43. The top of the connecting plate 42 is fixedly connected to the support base 43, which is used to fix the motor 44 and provide a stable mounting support for the motor 44. The motor 44 is internally fixedly connected to the support base 43, providing power for the rotation of the rotating shaft 45. The internal rotating connection of 42 has two rotating shafts 45. The rotating shafts 45 transmit the rotational power of the motor 44 to the soil drill 47 and also serve as the mounting carrier for the transmission assembly 46. The transmission assembly 46 is fixedly connected to the outside of the rotating shafts 45. The soil drill 47 is a component that directly contacts the soil to perform soil loosening operations and cuts and loosens the soil. The bottom of the soil drill 47 is fixedly connected to the drill bit 48, which facilitates better soil loosening. The outside of the soil drill 47 is fixedly connected to the loosening blade 49, which is used to expand the loosening range.

[0036] The transmission assembly 46 includes two pulleys 461. The pulleys 461 rotate via a rotating shaft 45 driven by a motor 44. Through the friction of the transmission belt 462, the other pulley 461 and the corresponding rotating shaft 45 rotate synchronously. The two pulleys 461 are internally fixedly connected to the outside of the two rotating shafts 45. The transmission belt 462 is externally coupled to the two pulleys 461. The transmission belt 462 is used to transmit power between the two pulleys 461.

[0037] Reference Figures 2 to 4 One end of the spring a22 is fixedly connected to the bottom of the handle 1. The two limiting posts 27 are slidably connected to the inside of the mounting base 3. The bottom of the connecting rod 21 is fixedly connected to the inside of the connecting rod 23. The sliding ball 282 is slidably connected to the inside of the mounting base 3. One of the rotating shafts 45 is fixedly connected to the drive end of the motor 44. The other rotating shaft 45 is fixedly connected to the outside of the fixing block 5. The sampling cylinder 6 is fixedly connected to the inside of the connecting plate 42. The sampling cylinder 6 is provided with scale lines 7 on the outside.

[0038] Working principle: First, the operator presses the handle 1 by hand. Since one end of the spring a22 is connected to the handle 1, the handle 1 can squeeze the spring a22 on the connecting rod 21, so that the spring a22 is in a compressed state in the connecting rod 23. The connecting rod 23 can drive the push rod 24 to move downward, thereby deforming the spring b26 and causing the limiting post 27 to slide into the groove of the mounting base 3 for fixation. At the same time, the sliding ring 281 and the sliding ball 282 also slide into the groove of the mounting base 3, thereby installing the sampling cylinder 6.

[0039] The cylinder 41 in the mounting base 3 is started. The cylinder 41 drives the connecting plate 42 and all the structures connected to the connecting plate 42 to move downward. Then, the motor 44 is started. The motor 44 drives the rotating shaft 45 connected to the motor 44 to rotate. The rotating shaft 45 drives the pulley 461 and the transmission belt 462 to move, so that another rotating shaft 45 rotates. Finally, the soil drill 47, drill bit 48 and loosening blade 49 on the left and right sides of the sampling tube 6 rotate, and the soil is loosened before the sampling tube 6 collects soil.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
