Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a multi-degree-of-freedom robotic arm-type precise soil sampling point deployment device. Background Technology

[0002] Multi-degree-of-freedom robotic arms can achieve flexible and precise motion control in three-dimensional space. With a wide range of motion and high positioning accuracy, they can accurately reach designated soil sampling points according to a pre-set sampling plan. Whether in complex mountainous terrain or regular farmland areas, the robotic arm can overcome terrain obstacles and accurately place the sampling device at the target sampling point, avoiding sampling position deviations caused by manual operation or limitations of traditional sampling equipment. This ensures that the collected soil samples are representative and provides a reliable data foundation for subsequent soil analysis and research.

[0003] Currently, during soil sampling, it is necessary to remove surface impurities from the soil within the sampling area to ensure a flat surface. Existing methods typically involve manual cleaning, which can easily damage the soil, resulting in more impurities being mixed into the soil during subsequent sampling. Furthermore, for deeper soil samples (such as those more than 50cm below the surface), manual excavation can easily cause collapse due to uneven stress. Utility Model Content

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a multi-degree-of-freedom robotic arm-type soil sampling point precision placement device includes a bottom beam 1, which has a U-shaped structure. Two support plates 2 are slidably connected to the top surface of the bottom beam 1. A support rod 3 is fixedly connected between the two support plates 2. A limit plate 4 is slidably connected to the side wall of the support rod 3. An installation plate 5 is fixedly connected to the top surface of the limit plate 4. An electric push rod 6 is fixedly connected to the top surface of the installation plate 5. A circular shell 7 is fixedly connected to the output end of the electric push rod 6 through the installation plate 5.

[0026] A rotating shaft 8 is rotatably connected to the inner wall of the round shell 7. The bottom end of the rotating shaft 8 passes through the round shell 7 and is equipped with a grinding wheel 9. A partition component and a transmission component are provided inside the round shell 7.

[0027] The round shell 7 also contains a dust collection component.

[0028] The partitioning component includes an annular plate 14 fixedly connected to the bottom surface of the inner cavity of the circular shell 7. Two partitions 13 are fixedly connected between the side wall of the annular plate 14 and the inner wall of the circular shell 7. The inner cavity of the annular plate 14 is the transmission zone, and the side wall of the circular shell 7 has a through groove. The side of the annular plate 14 near the through groove is the dust collection zone, and the other side of the partitions 13 is the flow guiding zone. By dividing the interior of the circular shell 7 into multiple different working areas, they can work together when cleaning the sampling area.

[0029] like Figure 3 and Figure 5 As shown, the vacuuming assembly includes a collection box 21 disposed in the vacuuming area. The collection box 21 has an arc-shaped structure, a through groove, and an opening at the top. The annular plate 14 and the side wall of the circular shell 7 are respectively provided with several ventilation holes 23. The side of the collection box 21 near the annular plate 14 is a breathable layer, and several hoses 22 are fixedly connected to the side wall of the collection box 21.

[0030] The transmission assembly includes a first bevel gear 17 fixedly connected to the side wall of the rotating shaft 8, a first motor 15 fixedly installed on the top surface of the inner cavity of the round shell 7, and a second bevel gear 16 fixedly connected to the output end of the first motor 15 and meshing with the first bevel gear 17, for driving the grinding wheel 9 to rotate.

[0031] A support plate is fixedly connected to the bottom surface of the inner cavity of the round shell 7. A fan blade 25 is rotatably connected to the side wall of the support plate. A third bevel gear 24 is fixedly connected to one end of the fan blade 25. The third bevel gear 24 meshes with the first bevel gear 17.

[0032] Specifically, when the fan blade 25 is rotating at high speed, the external airflow needs to enter the collection box 21 through the hose 22 to provide airflow support for the fan blade 25. At this time, suction is generated in the hose 22 to absorb the debris and impurities generated during cleaning into the collection box 21. Since one side of the collection box 21 is a breathable layer, the airflow can pass through, while the particulate impurities are blocked in the collection box 21.

[0033] In addition, the wind generated by the rotating fan blades 25 blows towards the first motor 15, and the airflow is discharged from the circular shell 7 through the vent 23. The wind can also be used to cool down the first motor 15.

[0034] like Figure 4 As shown, a cylinder 18 is fixedly connected to the bottom end of the rotating shaft 8. A connecting rod 19 is installed inside the cylinder 18. The grinding wheel 9 is fixedly connected to the bottom end of the connecting rod 19. A bolt 20 is threadedly connected to the side wall of the cylinder 18, and the bolt 20 is threadedly connected to the connecting rod 19. Specifically, in this solution, the grinding wheel 9 is preferably used for cleaning. After the designated area is cleaned, the grinding wheel 9 can be disassembled and replaced with other tools such as a drill bit, which facilitates soil excavation and effectively saves fatigue and collapse caused by manual excavation.

[0035] like Figure 1 As shown, a second motor 11 is fixedly connected to the side wall of the bottom beam 1 and the support plate 2 respectively. A lead screw 10 is rotatably connected to the side wall of the bottom beam 1 and the support plate 2 respectively. A threaded sleeve is threaded to the side wall of the lead screw 10. The lower threaded sleeve is fixedly connected to the support plate 2, and the upper threaded sleeve is fixedly connected to the limiting plate 4. A positioning rod 12 is fixedly connected to the side wall of the bottom beam 1 and the support plate 2. The support plate 2 and the limiting plate 4 are slidably connected to the positioning rod 12 respectively.

[0036] The three-axis drive method and control principle are both existing mature technologies. In this solution, they are used to drive the grinding wheel 9 to move in three axes, thereby efficiently cleaning the soil sampling points. Therefore, they will not be described in detail.

[0037] The working principle of this utility model is as follows: First, the device is moved to the designated area. Then, a suitable grinding wheel 9 is selected and connected to the cylinder 18 through the connecting rod 19 and fixed with bolts 20. Next, the first motor 15 and the second motor 11 are started. The second motor 11 drives the lead screw 10 to rotate. The lead screw 10 controls the movement position of the cylindrical shell 7 through the screw sleeve. At the same time, the electric push rod 6 drives the grinding wheel 9 to descend through the cylindrical shell 7, so that it contacts the ground and grinds and cleans the impurities on the ground surface, making it easier to expose the soil.

[0038] At the same time, when the first motor 15 drives the first bevel gear 17 to rotate through the second bevel gear 16, the first bevel gear 17 simultaneously drives the rotating shaft 8 and the third bevel gear 24 to rotate. The third bevel gear 24 drives the fan blade 25 to rotate rapidly, which generates suction in the collection box 21 and the hose 22. The hose 22 facilitates the adsorption of dust and debris generated during grinding into the collection box 21, avoiding dust pollution of the environment and affecting the operator's vision.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
