[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 7 The present invention describes the above technical solution in detail through the following embodiments:

[0026] A soil sampling device for agricultural engineering comprises: a sampler 1; a resistance-reducing groove 2 is provided on one side of the sampler 1; a sleeve 3 is fixedly connected to the top of the sampler 1; pedals 4 are provided on both sides of the sleeve 3; an end of the pedal 4 close to the sleeve 3 is fixedly connected to a rotating shaft 5; the outer surfaces of both ends of the rotating shaft 5 are rotatably connected to fixed blocks 6, and the fixed blocks 6 are fixedly connected to the sampler 1; a material return mechanism 7 is provided inside the sampler 1 to prevent the soil sample from being stuck inside the sampler 1; the user places the sampler 1 on the soil to be sampled, and then steps down on the pedal 4 to apply pressure to the pedal 4, the pedal 4 drives the rotating shaft 5, the rotating shaft 5 drives the fixed block 6, and the fixed block 6 drives the sampler The sampler 1 moves downward, so that the sampler 1 is inserted into the soil to take out the soil. The inclined surface at the bottom of the sampler 1 and the resistance reduction groove 2 can reduce the resistance between the sampler 1 and the soil when the sampler 1 is inserted into the soil, so that the sampler 1 can be quickly inserted into the soil for sampling. The material removal mechanism 7 includes: a material removal plate 8 is provided inside the sampler 1, and the material removal plate 8 is adapted to the sampler 1. A fixing rod 9 is fixedly connected to the top center of the material removal plate 8. The top end of the fixing rod 9 passes through the sleeve 3 and extends to the handle 10. The handle 10 is fixedly connected to the fixing rod 9; a first spring 1 is provided between the material removal plate 8 and the sampler 1. 1. The first spring 11 is sleeved on the outer surface of the fixing rod 9; the fixing rod 9 is provided with a locking mechanism 12 inside to prevent the stripping plate 8 from automatically ejecting the soil sample inside the sampler 1 after sampling. The user presses the locking mechanism 12 to separate the fixing rod 9 from the sleeve 3. At the same time of separation, the first spring 11 generates elastic recovery to push the stripping plate 8, and the stripping plate 8 drives the fixing rod 9, so that the fixing rod 9 slides downward inside the sleeve 3, thereby pushing out the soil sample inside the sampler 1. After the sampler 1 takes out the soil sample, the user can control the automatic discharge of the soil sample inside the sampler 1 by himself, which solves the problem that the existing soil sampling device does not have The function of returning the material causes the soil sample to be stuck inside the soil collection device, requiring the user to use tools to remove the soil inside the soil collection device, which is a problem of poor practicality. The locking mechanism 12 includes: a cavity 13 is opened inside the fixing rod 9, a latch 14 is arranged inside the cavity 13, a matching slot 15 is opened near the latch 14 at the sleeve 3, a second spring 16 is provided at one end of the latch 14 away from the slot 15, and the second spring 16 is arranged inside the cavity 13. Both sides of the latch 14 are fixedly connected to a limiting slider 17, and a first slide groove 18 is opened near the limiting slider 17 at the fixing rod 9, and the limiting slider 17 is slidably connected to the first slide groove 18;A pressing rod 19 is provided at the top of the latch 14. The top end of the pressing rod 19 passes through the fixed rod 9 and the handle 10 and extends to the outside of the handle 10. A matching inclined slot 20 is provided near the pressing rod 19 on the latch 14. The user can press the pressing rod 19, which slides downward inside the fixed rod 9 while squeezing the latch 14 through the inclined slot 20 on the latch 14. This causes the latch 14 to slide toward the second spring 16 through the cooperation of the limiting slider 17 and the first slide slot 18. The latch 14 separates from the slot 15 inside the sleeve 3, and the fixed rod 9 also separates from the sleeve 3.

[0027] like Figure 5 As shown, the outer surface of the pressing rod 19 located inside the fixed rod 9 is fixedly connected to a circular plate 21, and the fixed rod 9 is provided with a corresponding limiting groove 22 near the circular plate 21. The circular plate 21 is slidably connected to the limiting groove 22, which can limit the moving stroke of the pressing rod 19 and prevent the pressing rod 19 from separating and falling off from the inside of the fixed rod 9.

[0028] like Figure 2 and Figure 7 As shown, both sides of the inner wall of the sleeve 3 are fixedly connected with a limit strip 23, and the fixing rod 9 is provided with a second sliding groove 24 near the limit strip 23. The limit strip 23 is slidably connected to the second sliding groove 24, which can limit the fixing rod 9 and prevent the fixing rod 9 from rotating inside the sleeve 3.

[0029] like Figure 3 As shown, damping pads 25 are provided on the tops of the pedals 4 , and the damping pads 25 are fixedly connected to the pedals 4 , respectively, to increase the roughness of the surface of the pedals 4 and prevent the user from slipping when stepping on the pedals 4 .

[0030] like Figure 1 and Figure 4 As shown, silicone pads 26 are provided on both sides of the outer surface of the handle 10, and the silicone pads 26 are fixedly connected to the handle 10, thereby improving the comfort of the handle surface.

[0031] Working principle: The user places the sampler 1 on the soil to be sampled, and then steps down on the pedal 4 to apply pressure to the pedal 4. The pedal 4 drives the rotating shaft 5, the rotating shaft 5 drives the fixed block 6, and the fixed block 6 drives the sampler 1 to move downward, so that the sampler 1 is inserted into the interior of the soil to take out the soil. The inclined surface setting at the bottom of the sampler 1 and the setting of the resistance reduction groove 2 can reduce the resistance between the sampler 1 and the soil when the sampler 1 is inserted into the soil, so that the sampler 1 can be quickly inserted into the interior of the soil for sampling.

[0032] When the user needs to take out the soil sample, the user can press the pressing rod 19, and the pressing rod 19 drives the circular plate 21 to slide downward through the internal limiting sliding groove 22 of the fixing rod 9. At the same time, the latch 14 is squeezed by the inclined groove 20 on the latch 14, so that the latch 14 slides in the direction of the second spring 16 through the cooperation of the limiting slider 17 and the first sliding groove 18. The latch 14 is separated from the card slot 15 inside the sleeve 3, and the fixing rod 9 is also separated from the sleeve 3. When the fixing rod 9 is separated from the sleeve 3, the first spring 11 produces elastic recovery to push the stripping plate 8, and the stripping plate 8 drives the fixing rod 9, so that the fixing rod 9 slides downward inside the sleeve 3, thereby pushing out the soil sample inside the sampler 1. After the soil sample is taken out by the sampler 1, the soil sample inside the sampler 1 can be automatically discharged by the user himself, which solves the problem that the existing soil sampling device does not have the function of removing the material, resulting in the soil sample being stuck inside the soil collection device and requiring the user to use tools to remove the soil inside the soil collection device, which is less practical.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
