Technical Field
[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device. Background Art
[0002] After sampling soil, it is usually difficult to remove the soil sample from the sampling tube of a traditional sampler. In addition, it is also difficult to clean the soil sample inside the sampling tube of a traditional sampler, which is not conducive to soil sampling.
[0003] To solve the above problems, there is a soil sampler (Announcement No. CN218067125U) that can easily remove the soil sample collected in the sampling tube and clean the sampling tube, and can also facilitate the sampler to better apply force for sampling.
[0004] However, the above solution applies force to the soil sampler by stepping on the pedal, which is more suitable for places with loose soil. When the soil is relatively dry and hard, the sampling process may require more time and force due to the resistance of the dry and hard soil, resulting in reduced sampling efficiency; and when it is necessary to collect deep soil, it will be even more troublesome. Due to the obstruction of the pedal, the collection depth of the soil sampler is limited, and its application is not flexible and convenient enough. Utility Model Content
[0005] The purpose of the present utility model is to provide a soil sampling device to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a soil sampling device, including a planetary reducer, which is connected to a first connecting shaft and a second connecting shaft; with the help of the planetary reducer to control the rotation of the drill rod, deep soil can be easily taken out even in hard soil.
[0007] Insert shaft, wherein several insert shafts are provided, and the insert shafts are connected to the drill rod and the extension rod. The first connecting shaft, the second connecting shaft and the extension rod are provided with a card slot inside, and an anti-drop bolt is installed inside the card slot. The extension rod can change the soil extraction depth, and is more flexible to use;
[0008] A spherical shell is installed inside the plug shaft and passes through the plug shaft. The inner wall of the plug shaft is provided with a spiral tube, and a spring is sleeved on the spiral tube. The spring is connected to the spherical shell to improve the stability of the connection between the drill rod and the extension rod;
[0009] A foot pedal is connected to a positioning rod, which is connected to a planetary reducer. The foot pedal can prevent the drill rod from tilting when taking soil.
[0010] Furthermore, a limiting ring is fixedly connected to the surface of the planetary reducer, and the positioning rod passes through the limiting ring, so the planetary reducer and the positioning rod can be disassembled, making it more convenient to carry.
[0011] Furthermore, a crank is inserted into the lower part of the surface of the first connecting shaft, and the rotation of the planetary reducer is controlled by means of the crank, which saves more effort during use.
[0012] Furthermore, the surfaces of the first connecting shaft, the second connecting shaft and the extension rod are all provided with receiving grooves, and the receiving grooves are used to accommodate anti-dropping bolts. The inner walls of the slots are provided with anti-loss grooves, and the anti-dropping bolts are connected to limiting columns. When the anti-dropping bolts are loosened, the anti-dropping bolts will not fall out of the slots, thereby avoiding the loss of the anti-dropping bolts.
[0013] Compared with the prior art, the beneficial effects of the present invention are: the plug shaft of the drill rod is plugged into the second connecting shaft of the planetary reducer, the foot pedal is placed on the ground, the planetary reducer is sleeved on the positioning rod through a limit ring, and the first connecting shaft is rotated using a crank.

The screw tube 17 is sleeved with a spring 18, and the spring 18 is connected to the spherical shell 9. The spherical shell 9 is clamped in the slot 16 to improve the stability of the connection between the drill rod 11 and the second connecting shaft 7 and prevent the drill rod 11 from being separated from the second connecting shaft 7. The plug shaft 8 is a quadrangular prism and the slot 16 is a quadrangular groove, so the power transmission is stable.
[0025] The foot pedal 2 is connected to a positioning rod 1, and the positioning rod 1 is connected to the planetary reducer 3. The foot pedal 2 is placed on the ground to support the planetary reducer 3 and prevent the planetary reducer 3 from shaking.
[0026] In this embodiment, if Figure 2 As shown, a sun gear 15 and a planet carrier 14 are rotatably installed inside the planetary reducer 3, the first connecting shaft 4 is connected to the sun gear 15, and the second connecting shaft 7 is fixedly connected to the planet carrier 14. The planet carrier 14 is rotatably connected to a planet gear 13 that meshes with the sun gear 15, and the planet gear 13 meshes with the ring gear 12 on the inner wall of the planetary reducer 3. The sun gear 15 drives the planet gear 13 to rotate, and the planet gear 13 drives the planet carrier 14 to rotate, and the planet carrier 14 drives the second connecting shaft 7 to rotate. When the drill rod 11 is connected to the second connecting shaft 7, drilling can be carried out.
[0027] In this embodiment, if Figure 1 As shown, the surface of the planetary reducer 3 is fixedly connected to a limiting ring 6, and the positioning rod 1 passes through the limiting ring 6. The planetary reducer 3 is slidably connected to the positioning rod 1 through the limiting ring 6, and can be disassembled, which is more convenient to carry.
[0028] In this embodiment, if Figure 1As shown, a crank 5 is inserted into the lower part of the surface of the first connecting shaft 4. The crank 5 is plug-in connected to the first connecting shaft 4, which makes it easy to remove the crank 5. It is more labor-saving to use the crank 5 to drive the first connecting shaft 4 to rotate.
[0029] In this embodiment, if Figure 3 As shown, the ball shell 9 is fixedly connected to the limiting cap 19, and the spring 18 is inserted into the limiting cap 19. The limiting cap 19 can limit the spring 18 and prevent the ball shell 9 from falling.

At this time, the ball shell 9 is pushed into the card slot 16 by the spring 18 to realize the connection between the drill rod 11 and the planetary reducer 3. Then, the anti-dropping bolt 23 is tightened with the hexagonal wrench so that the anti-dropping bolt 23 is screwed into the screw tube 17. The anti-dropping bolt 23 presses against the ball shell 9 to ensure that the ball shell 9 does not move, thereby preventing the drill rod 11 from falling off during the drilling process. The connection method of the extension rod 10 with the second connecting shaft 7 and the drill rod 11 is the same principle;
[0034] The positioning rod 1 passes through the limiting ring 6, and the foot pedal 2 is placed on the ground and stepped on. At this time, the drill rod 11 is in contact with the ground. The crank 5 is used to drive the first connecting shaft 4 to rotate, and the planetary reducer 3 amplifies the torque and outputs it to the drill rod 11. During the drilling process, the planetary reducer 3 moves down along the positioning rod 1 to realize drilling sampling of the land.
