[0002] A soil sampler is a tool used to obtain soil samples. It is widely used in agriculture, forestry, geological surveys, environmental protection, and scientific research units. After collecting soil, the soil sampler conducts testing and analysis to determine whether the sampled soil meets the conditions for crop growth, thereby increasing yields. China has authorized a utility model patent (Announcement No.: CN220960653U) that discloses a soil sampling device. By setting a sampling cylinder instead of a Luoyang shovel for soil sampling, the time required for soil sampling is reduced, the labor consumed by staff is reduced, and the degree of damage to the soil layer is reduced.
[0003] However, the above device still has some shortcomings when in use: specifically, in the prior art, the pedal is only fixedly connected to the connecting block, and its force point is concentrated at the connection point. In actual use, due to frequent use, stepping on it with different forces, and possible improper operation, the single-point force design can easily cause fatigue fracture of the pedal. Damage to the pedal not only affects the normal progress of the sampling work, but also may pose a safety hazard to the operator. Therefore, a soil detection sampling device is proposed to address the above situation. Utility Model Content

[0007] The pedal is provided with a screw hole which is matched with the external thread.
[0008] Slide grooves are provided on both sides of the outer wall of the sampling tube, with two slide grooves on each side, and a spring is fixedly connected to the inside of each slide groove.
[0009] The auxiliary support mechanism has a first connecting member, a slider is fixedly connected to the first connecting member, the slider slides in cooperation with the slide groove, the bottom of the slider is fixedly connected to the spring, a support rod is provided on the slider, and the end of the support rod away from the first connecting member is connected to the second connecting member, a rectangular frame is provided on the second connecting member, a positioning bolt is provided on the rectangular frame, and the positioning bolt passes through the rectangular frame and is connected to the bottom of the pedal.
[0010] Preferably, the number of auxiliary support mechanisms is four.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-4 A soil detection sampling device includes a sampling tube 1, a pedal 3 and an auxiliary support mechanism. The sampling tube 1 has a working chamber. Both sides of the outer wall of the sampling tube 1 are provided with through grooves 101, and the through grooves 101 are connected to the working chamber. A driving assembly is provided in the working chamber, and a connecting rod 2 is provided on the driving assembly. The connecting rod 2 passes through the through groove 101, and the passing end of the connecting rod 2 is provided with an external thread 201.
[0025] The driving assembly is the power source for the sampling operation. The components of the driving assembly include a driving block and other structures, which are the same as the relevant components used for sampling in the prior art (Announcement No.: CN220960653U), and will not be described in detail here.
[0026] The pedal 3 is provided with a screw hole 301, which is threadedly matched with the external thread 201, so that the pedal 3 can be installed as follows. Figure 1 As shown, it is in a horizontal state.
[0027] Slide grooves 4 are provided on both sides of the outer wall of the sampling tube 1 , with two slide grooves 4 on each side. A spring 8 is fixedly connected to the interior of each slide groove 4 .
[0028] The auxiliary support mechanism has a first connecting member 5, to which a slider 501 is fixedly connected. The slider 501 slides in cooperation with the slide groove 4. The bottom of the slider 501 is fixedly connected to the spring 8. A support rod 7 is provided on the slider 501. The end of the support rod 7 away from the first connecting member 5 is connected to a second connecting member 6. A rectangular frame 601 is provided on the second connecting member 6.

[0029] In this embodiment, when in use, the staff steps on the pedal 3 to make the pedal 3 descend to perform soil sampling operations. During this process, the pressure exerted on the pedal 3 will act on the slider 501 through the support rod 7, causing the slider 501 to slide and descend in the slide groove 4, and then the slide groove 4 squeezes the spring 8. In the process of stepping on the pedal 3, the concentration point of the pedal 3 during the force process is effectively dispersed, so that the force during the stepping process is more evenly distributed, which not only greatly reduces the burden on the connecting rod 2 and its connection point, but also improves the overall stability and durability of the pedal 3, effectively reduces the risk of the pedal 3 breaking, and extends the service life of the device.
[0030] When the pedal 3 needs to be replaced, the positioning bolt 602 is unscrewed from the rectangular frame 601 , and then the pedal 3 is rotated and removed from the connecting rod 2 .
[0031] In this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the number of auxiliary support mechanisms is four.
[0032] In this embodiment, an auxiliary supporting mechanism is provided in each chute 4 .
[0033] In this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the first connecting member 5 and the second connecting member 6 have the same structure, both including a rotating shaft and a fixed plate, a circular hole on the fixed plate, and two fixed plates. The rotating shaft rotates and fits in the circular hole. The two ends of the support rod 7 are respectively connected to the rotating shaft, and the slider 501 and the rectangular frame 601 are respectively fixedly connected to the two fixed plates.
[0034] In this embodiment, by connecting the support rod 7 to the rotating shaft, when the pedal 3 is stepped on, the slider 501 can slide down and then be auxiliary supported by the spring 8.
[0035] In this embodiment, Figure 4 As shown, there are two reserved holes on the rectangular frame 601 , and the reserved holes cooperate with the positioning bolts 602 .
[0036] In this embodiment, the reserved holes are provided for assembling the positioning bolts 602 .
[0037] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the top of the pedal 3 has anti-slip grooves, and the bottom of the pedal 3 has a bolt hole, which is threadedly matched with the positioning bolt 602.
[0038] In this embodiment, the provision of the anti-skid pattern can increase the friction with the soles of the staff's shoes to avoid slipping.
[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
