Subsequently, the mobile control assembly pushes the soil rod 33 to move the cone head 17 relative to the main cylinder 16 to achieve the separation of the two.

[0039] During this process, the scraper blade 36 and the support rod 34 rotate in a direction away from the soil sampling rod 33 under the restriction of the elastic telescopic rod 35 until one end of the scraper blade 36 is located outside the area between the main tube 16 and the cone head 17.

In the process of separation of the cone head 17 and the main tube 16, the soil picking rod 33 pulls the support rod 34, and the elastic telescopic rod 35 is first compressed and then stretched until it reaches Figure 5 It can be understood that the scraper blade 36, the support rod 34 and the elastic telescopic rod 35 can be specifically set, as long as the scraper blade 36 can be extended and retracted, without limitation, and the setting is until the end of the scraper blade 36 away from the support rod 34 is located outside the area between the main tube 16 and the cone head 17, so that the scraper blade 36 can scrape the soil and achieve the expected effect.

[0046] Preferably, in order to improve the stability of the motor 4 , a plurality of motor reinforcement plates 3 are fixed on the collar 1 5 , and the motor reinforcement plates 3 are also fixedly connected to the motor 4 .

[0047] Preferably, the input shaft 6 and the output shaft 10 are both arranged perpendicular to the transmission shaft 8; the arc-shaped telescopic cylinder 21 adopts an arc-shaped structure, and the center of the arc-shaped telescopic cylinder 21 is located on the axis of the transmission shaft 8. The angle between the input shaft 6 and the output shaft 10 can be adjusted by telescoping the arc-shaped telescopic cylinder 21, and no matter how it is adjusted, the bevel gear 2 23 and the bevel gear 3 24 are meshed and connected with the bevel gear 1 22, that is, stable and reliable transmission is maintained. In addition, the combined limit of the collar 1 5, the collar 2 11 and the arc-shaped telescopic cylinder 21 ensures the reliability of the transmission of the input shaft 6 to the output shaft 10.

[0048] like Figure 1 As shown, as a preferred embodiment of the present invention, the holding assembly includes a holding rod 1 and a gripping rod 2. A holding rod 1 is fixed on both sides of the ring 5, and the holding rod 1 is arranged parallel to the transmission shaft 8. A U-shaped gripping rod 2 is also fixed on the holding rod 1. Through the arrangement of the holding rod 1 and the gripping rod 2, it is convenient to hold the device stably, which is conducive to stable and reliable operation of the device for sampling.

[0049] like Figure 1-5As shown, as a preferred embodiment of the present invention, the mobile control assembly includes a linear telescopic cylinder 12, a fixed plate 13, a connecting rod 14, a rotating ring 19, a fixed ring 20, a fixed block 25, a movable plate 1 28, a spring 29, a guide rod 30, a movable plate 2 31 and an adjusting nut 32. The movable plate 1 28 and the movable plate 2 31 are slidably arranged in the cavity 27. The end of the soil-taking rod 33 away from the cone head 17 is fixedly connected to the movable plate 2 31. A plurality of guide rods 30 are circumferentially distributed and fixed on the outer side of the movable plate 1 28. The guide rods 30 slide through the movable plate 2 31. The side of the movable plate 2 31 away from the movable plate 1 28 is threadedly connected with an adjusting nut 32 on the guide rod 30. A spring 29 is also sleeved on the guide rod 30 between the movable plate 1 28 and the movable plate 2 31. A plurality of connecting rods 14 are fixedly distributed circumferentially on the side of the movable plate 1 28 away from the movable plate 2 31. The connecting rod 14 slides out from the end of the main tube 16 away from the cone head 17. The end of the connecting rod 14 away from the movable plate 1 28 is fixedly connected to a rotating ring 19 rotatably connected to the output shaft 10. A fixed ring 20 is also rotatably connected to the output shaft 10, and the fixed ring 20 is also rotatably connected to the rotating ring 19. A fixed plate 13 is also fixed to the sleeve ring 2 11, and a linear telescopic cylinder 12 is fixed to the fixed plate 13. The output end of the linear telescopic cylinder 12 is fixedly connected to the fixed ring 20 via a fixed block 25.

[0050] Preferably, the main cylinder 16 and the soil taking rod 33 are coaxially arranged, the connecting rod 14 is located outside the output shaft 10, and the linear telescopic cylinder 12 is arranged parallel to the output shaft 10. The structure of the rotating ring 19 and the fixed ring 20 can be conventionally arranged, so that when the linear telescopic cylinder 12 drives the fixed ring 20 and the rotating ring 19 to move as a whole, the rotation of the main cylinder 16 can also drive the multiple connecting rods 14 to rotate, so that the rotating ring 19 rotates synchronously with the output shaft 10.

[0051] Preferably, guide grooves (not shown) are provided on the outer sides of the movable plate 1 28 and the movable plate 2 31, and guide edges (not shown) slidably connected to the guide grooves are fixed on the wall of the cavity 2 27. Through the arrangement of the guide grooves and the guide edges, the movable plate 1 28 and the movable plate 2 31 can rotate synchronously with the main cylinder 16, thereby improving reliability.

[0052] In the embodiment of the present invention, the movement of the connecting rod 14 can be controlled by the extension and retraction of the linear telescopic cylinder 12, thereby driving the movable plate 1 28 to move. The setting of the spring 29, the guide rod 30 and the adjusting nut 32 has an elastic supporting effect on the movable plate 2 31, which can buffer the drilling when taking soil and improve the application effect. Moreover, the initial distance between the movable plate 1 28 and the movable plate 2 31 can be adjusted by rotating the adjusting nut 32, that is, the initial elastic supporting force can be adjusted, and the application is flexible and convenient.

[0053] In addition, there is no specific limitation on the power supply, control, model and circuit connection of the motor 4 and the linear telescopic cylinder 12, and they can be flexibly set in practical applications. The circuits, electronic components and modules involved are all prior art, and those skilled in the art can fully implement them. It is needless to say that the content protected by the present invention does not involve improvements to software and methods.

[0054] The above embodiment of the present invention provides a soil detection sampler, which has the following specific advantages:

[0055] Firstly, the design of the holding assembly is optimized, wherein the combination of the holding rod 1 and the gripping rod 2 enables the operator to hold the device stably and comfortably during the sampling process, thereby ensuring the stability and accuracy of the sampling operation.

[0056] Secondly, in the process of drilling and sampling, the close cooperation between the main cylinder 16 and the cone head 17 is the key. When the two are connected, the adjustable angle drive assembly can drive the main cylinder 16 to rotate, and realize the drilling function through the spiral plate 15. When the drilling reaches the specified depth, the mobile control assembly will play a role. Through the extension and contraction of the linear telescopic cylinder 12, the connecting rod 14 can be controlled to move, thereby driving the movable plate 1 28 to move. This design not only utilizes the elastic support effect of the spring 29, the guide rod 30 and the adjusting nut 32 to buffer the impact force during the drilling process and improve the application effect, but also through the adjustment of the adjusting nut 32, the initial distance between the movable plate 1 28 and the movable plate 2 31, that is, the initial elastic support force, can be flexibly adjusted, making the application more flexible and convenient.

[0057] In addition, the scraper blade 36 and the support rod 34 can rotate to the side away from the soil sampling rod 33 under the limiting action of the elastic telescopic rod 35. This design enables the scraper blade 36 to smoothly scrape the soil in the outer area between the main cylinder 16 and the cone head 17, so that the soil falls smoothly into the cavity 26, thereby completing soil sampling. After the sampling is completed, the mobile control component will control the soil sampling rod 33 to return to its original position, and the scraper blade 36 will return to its original position under the elastic force of the elastic telescopic rod 35, and the main cylinder 16 and the cone head 17 will be closed again. By controlling the main cylinder 16 to rotate in the opposite direction, the device can be smoothly exited.

[0058] It is worth mentioning that the adjustable angle drive assembly of the present invention not only has the function of driving the overall rotation of the main cylinder 16 and the cone head 17, but also can adjust the angle between the main cylinder 16 and the holding assembly. This function enables the sampler to adapt to the soil sampling needs under different environmental conditions, greatly broadening its scope of application. Specifically, the angle between the input shaft 6 and the output shaft 10 can be easily adjusted by the extension and contraction of the arc-shaped telescopic cylinder 21. Regardless of how the angle is adjusted, bevel gear two 23 and bevel gear three 24 always maintain meshing connection with bevel gear one 22, ensuring the stability and reliability of the transmission. In addition, the combined limiting design of collar one 5, collar two 11 and arc-shaped telescopic cylinder 21 further enhances the reliability of the transmission of the input shaft 6 to the output shaft 10, avoiding the problem of transmission failure that may occur during the sampling process.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
