Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, specifically a labor-saving soil sampling device. Background Technology

[0002] A soil sampling device is a tool used to obtain soil samples, mainly for soil testing and fertilizer recommendation, soil monitoring, and farmland quality evaluation.

[0003] Chinese patent CN210427078U discloses a soil sampling device. This utility model supports the sampling tube off the ground with a support frame, so that the sampling tube can be aligned with the sampling point before use. The outer wall of the sampling tube is threaded and connected to the ring thread, so that the sampling tube can move vertically after being aligned with the sampling point, which is conducive to the vertical insertion of the sampling tube into the sampling point for soil collection.

[0004] During use, the aforementioned equipment is supported by a sturdy and reliable support frame. This support frame is designed to ensure stability and accuracy during the sampling process. The inner sampling tube rotates vertically downwards to accurately enter the soil for sampling. As the sampling tube gradually penetrates deeper into the soil, its contact area with the soil increases accordingly. This increased contact area leads to increased friction during sampling. When a certain depth is reached, greater force is required to rotate the sampler in order to continue collecting samples effectively. This not only makes the entire operation less convenient and labor-saving but may also reduce work efficiency and speed due to the increased physical exertion. Optimization and improvement are needed. Utility Model Content

[0005] The purpose of this invention is to provide a labor-saving soil sampling device to solve the problem in the background art where, as the sampling tube gradually penetrates deeper into the soil, the contact area between the tube and the soil increases accordingly, and the friction also increases, making the entire operation process less convenient and labor-saving.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a labor-saving soil sampling device, comprising:

[0007] A support connecting plate is provided, with a hollow drill rod threadedly connected to its inner side, and a support mounting bracket is fixedly installed on its outer side.

[0008] The labor-saving sampling component is located at the top of the support connecting plate and includes a rotating bearing. A manual turntable is connected to the top of the rotating bearing, and a counterweight is provided at the top of the manual turntable. The labor-saving sampling component is used for labor-saving rotation of the hollow drill rod.

[0009] An adjustment and fixing assembly is provided at the bottom end of the support mounting frame. The adjustment and fixing assembly includes a telescopic adjustment rod, a bottom support block at the bottom end of the telescopic adjustment rod, a protective pad adhered to the bottom end of the bottom support block, and a plug-in rod on the inner side of the bottom support block. The adjustment and fixing assembly is used for multi-mode adjustment and fixing of the equipment.

[0010] Preferably, the top wall of the hollow drill rod is provided with an installation groove, and the installation groove is used for the fixed installation of the counterweight.

[0011] Preferably, the hollow drill rod is provided with an ejector rod on its inner side, and a pull ring is installed at the top of the ejector rod.

[0012] Preferably, a rotating connecting block one is installed on the inner bottom end of the support mounting frame, and a telescopic adjusting rod is connected to the bottom end of the rotating connecting block one, and a rotating connecting block two is fixedly connected to the bottom end of the telescopic adjusting rod.

[0013] Preferably, an adjustment plate is provided on the inner side of the bottom support block, and a reset elastic element is connected to the four corners of the bottom end of the adjustment plate.

[0014] Preferably, the top of the adjusting plate is slidably connected to a pressing slide plate, and the inner side of the pressing slide plate is threadedly connected to a bidirectional adjusting screw.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This utility model provides vertical support through a threaded connection between the hollow drill rod and the support connecting plate. Then, by rotating a manual turntable externally, which is threaded to the hollow drill rod and connected to a rotating bearing, the rotation of the manual turntable can be easily adjusted. The stable support connection improves the stability of drilling and sampling. Finally, a counterweight is installed at the top to increase the overall weight of the hollow drill rod, thereby increasing the downward pressure and achieving a labor-saving effect, thus improving the efficiency of sampling.

[0017] When placed on a flat surface, the bottom is protected and supported by a protective pad. On uneven ground, the sliding of the squeezing plate causes it to move downwards, causing the plug-in rod to pass through the bottom support block and directly plug into the ground. This setup allows for adjustment of the fixing method according to environmental needs, improving the applicability of the equipment and avoiding impact on sampling efficiency.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1-4 As shown, this application provides a labor-saving soil sampling device, including: a support connecting plate 1, a hollow drill rod 2 threadedly connected to the inner side of the support connecting plate 1, and a support mounting frame 3 fixedly installed on the outer side of the support connecting plate 1;

[0026] The top of the support connecting plate 1 is provided with a labor-saving sampling component, and the labor-saving sampling component includes a rotating bearing 4, and the top of the rotating bearing 4 is connected to a manual turntable 5.

[0027] Specifically, such as Figure 3 As shown, the top wall of the hollow drill rod 2 is provided with an installation groove 6, and the installation groove 6 is used for the fixed installation of the counterweight 7. The counterweight 7 is installed inside the installation groove 6 to increase the weight of the hollow drill rod 2, increase the downward pressure, and achieve the effect of saving effort.

[0028] Specifically, such as Figure 3As shown, a push rod 8 is provided on the inner side of the hollow drill rod 2, and a pull ring 9 is installed at the top of the push rod 8. After the hollow drill rod 2 has finished sampling, the pull ring 9 is grasped and the push rod 8 is squeezed to squeeze out the soil inside the hollow drill rod 2.

[0029] The top of the manual turntable 5 is equipped with a counterweight 7, and the labor-saving sampling component is used for the labor-saving rotation of the hollow drill rod 2;

[0030] The bottom end of the support mounting bracket 3 is provided with an adjustment and fixing component, which includes a telescopic adjustment rod 11. The bottom end of the telescopic adjustment rod 11 is provided with a bottom support block 13, and a protective pad 14 is glued to the bottom end of the bottom support block 13. A plug-in rod 16 is provided on the inner side of the bottom support block 13. The adjustment and fixing component is used for multi-mode adjustment and fixing of the equipment.

[0031] Specifically, such as Figure 2 As shown, a rotating connecting block 10 is installed on the inner bottom of the support mounting frame 3, and a telescopic adjusting rod 11 is connected to the bottom of the rotating connecting block 10. A rotating connecting block 2 12 is fixedly connected to the bottom of the telescopic adjusting rod 11. The telescopic adjusting rod 11 consists of a hollow rod and an internal moving rod. External adjustment is achieved by fixing with screws. The telescopic control controls the height between the rotating connecting block 10 and the rotating connecting block 2 12. The rotating connecting block 10 and the rotating connecting block 2 12 are respectively connected to the inner sides of the support mounting frame 3 and the bottom support block 13 for rotation at a certain angle.

[0032] Specifically, such as Figure 4 As shown, an adjustment plate 15 is provided on the inner side of the bottom support block 13, and a reset elastic member 17 is connected to the four corners of the bottom end of the adjustment plate 15. The adjustment plate 15 is located on the inner side of the bottom support block 13 and can slide up and down. After sliding down, the plug rod 16 can be pushed out. At this time, the reset elastic member 17 is squeezed, and the pressure is lost at the top of the adjustment plate 15. The reset elastic member 17 drives the adjustment plate 15 and the plug rod 16 to spring back to reset.

[0033] Specifically, such as Figure 4 As shown, the top of the adjusting plate 15 is slidably connected to the extrusion slide plate 18, and the inner side of the extrusion slide plate 18 is threadedly connected to the bidirectional adjusting screw 19. Under the rotation adjustment of the bidirectional adjusting screw 19, the extrusion slide plate 18 can slide and adjust at the top of the adjusting plate 15. By contacting the top wall of the bottom support block 13 at different positions of the inclined plane, the position of the adjusting plate 15 can be adjusted downward.

[0034] In this embodiment: vertical support is provided through the threaded connection between the hollow drill rod 2 and the support connecting plate 1. Then, the manual turntable 5 is rotated externally, and the manual turntable 5 is threadedly connected to the hollow drill rod 2. The connection of the rotating bearing 4 facilitates the adjustment of the rotation of the manual turntable 5. The stable support connection improves the stability of drilling and sampling. Then, the counterweight block 7 at the top is installed to increase the overall weight of the hollow drill rod 2, thereby increasing the downward pressure and achieving the effect of saving effort. When the bottom is placed on a flat surface, it is protected and supported by the protective pad 14. On uneven ground, the sliding of the extrusion plate 18 drives the extrusion plate 18 to move downward, causing the insertion rod 16 to pass through the bottom end of the bottom support block 13 and directly insert into the ground. The fixing method can be adjusted according to the environmental needs.

[0035] The specific solution is as follows: During use, the equipment can be stably fixed first. The fixing method can be selected according to the ground environment. On relatively flat ground, the protective pad 14 can be directly connected to the bottom support block 13 to contact the ground for anti-slip support. On uneven ground, the bidirectional adjusting screw 19 can be turned to move the extrusion plate 18 to both sides. Then, the adjusting plate 15 is extruded to push the plug rod 16 out from the bottom of the bottom support block 13. The bottom tip of the plug rod 16 can be directly inserted into the ground to complete the plugging and fixing. For uneven parts, the height can also be adjusted by the telescopic adjusting rod 11 to facilitate the adjustment of the level of the support connecting plate 1. Then, during the sampling process, the manual turntable 5 is rotated by hand, and the hollow drill rod 2 rotates and moves downward inside the support connecting plate 1. The counterweight block 7 is installed in the top mounting groove 6 of the hollow drill rod 2 to increase the gravity of the hollow drill rod 2 as it is turned downward, thus achieving the effect of saving effort. After the sampling is completed, the soil inside the hollow drill rod 2 is pushed out and collected by pushing the ejection rod 8.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
