Description

Technical Field

[0001] The utility model belongs to the technical field of soil loosening, and in particular relates to a soil loosening device. Background Art

[0002] The looseness of soil refers to the size of the gaps between its particles and the degree of porosity. Soil looseness is very important for plant growth because it directly affects the growth and development of the root system. Loose soil can provide more air and water to the root system, which helps plants absorb nutrients and water. Loose soil is also easier to be penetrated by the root system, allowing plants to take root better and grow steadily. Therefore, keeping the soil loose is an important way of soil management, which can be achieved by methods such as tillage, adding organic matter and improving soil structure. A soil quick loosening device is disclosed in the prior art. In order to solve the problem that when loosening the soil, the length of the drill bit is generally fixed, and soil samples of different depths cannot be collected, which affects the collection of soil data. By setting an electric telescopic rod, the soil of different depths is broken up during the operation of the drill bit, and the soil sampling of different depths is realized. However, the above technical solution needs to be handheld during the soil loosening process, and only the sliding rod is in contact with the ground. For the operator, the hand needs to continue to exert force for support, the stability of use is poor, and the drill bit is easy to deflect. Therefore, the inventor proposes a soil loosening device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific embodiment is a soil loosening device, and its structural schematic diagram is as follows Figure 1 , Figure 2As shown, it includes a fixed plate 1, a bottom ring 3, a pressing rod 7 and a supporting mechanism 4. The fixed plate 1 and the bottom ring 3 are spaced apart. A limiting tube 5 is installed vertically through the inside of the fixed plate 1. The limiting tube 5 is a hollow structure, and the pressing rod 7 slides vertically along the limiting tube 5. A plurality of guide rods 6 are installed between the bottom ring 3 and the fixed plate 1. The plurality of guide rods 6 are spaced apart around. A slip ring 2 is slidably installed outside the guide rod 6. A plurality of supporting mechanisms 4 are distributed around the outer circumferential surface of the slip ring 2. A limiting rod 8 is inserted on the upper part of the outer wall of the pressing rod 7, and a limiting hole 9 for matching the limiting rod 8 is provided on the upper end of the limiting tube 5.

[0024] Reference Figure 2 , Figure 3 The support mechanism 4 includes a support leg 10, an inner slide bar 12, and a fixed tube 11. The fixed tube 11 is fixedly connected to the outer wall of the slip ring 2. The inner slide bar 12 slides into the inside of the fixed tube 11. The support leg 10 is fixedly connected to the end of the inner slide bar 12 away from the fixed tube 11. The support leg 10 is vertically arranged and vertically distributed with the inner slide bar 12. A sliding groove is horizontally opened on the upper surface of the fixed tube 11. A moving block 15 sliding through the sliding groove is fixedly connected to the upper surface of the inner slide bar 12. An adjusting screw 14 is installed on the internal thread of the moving block 15. A fixed block 13 is fixed on the upper surface of the fixed tube 11. An adjusting screw 14 is rotatably installed in the fixed block 13. The adjusting screw 14 is horizontally arranged. A plug hole 19 is opened on the outer wall of the guide rod 6. A plug rod 20 is slidably installed on the outer wall of the slip ring 2. The plug rod 20 is adapted to be plugged into the plug hole 19.

[0025] Reference Figure 4 The interior of the pressing rod 7 is hollow, and a drill bit 18 is rotatably mounted at the bottom. A driving motor 17 is fixed inside the pressing rod 7, and the driving motor 17 is connected to the drill bit 18. A gripping rod 16 is fixedly connected to the outer wall of the top end of the pressing rod 7.

[0026] Working principle: When in use, the bottom of the bottom ring 3 is provided with a pulley, which can be pushed to move it to the position where the soil needs to be loosened, and then the adjusting screw 14 is turned, and the moving block 15 threadedly connected to the adjusting screw 14 slides along the fixed tube 11, driving the inner slide rod 12 to slide toward the outside of the fixed tube 11. At this time, the support leg 10 is forced to move gradually away from the slip ring 2, and then the insertion rod 20 is pulled out. After the insertion rod 20 leaves the socket 19, the slip ring 2 loses its supporting limiting force and can slide downward. After contacting the ground, the insertion rod 20 can be inserted into the socket 19 below again. The plug holes 19 are vertically spaced apart on the outer wall of the guide rod 6 to adapt to the fixation of the slip ring 2 at different heights. When the support leg 10 is fixed, the fixing ring and the bottom ring 3 have a stabilizing force. Then the limit rod 8 is pulled along the limit hole 9 to make the limit rod 8 leave the outer wall of the pressing rod 7. Then the pressing rod 7 is pressed by the grip rod 16, and the drive motor 17 is started. The drill bit 18 is lowered to loosen the soil. After completion, the pressing rod 7 is pulled up and the limit rod 8 is reset. Then the slide rod is pulled up and the support leg 10 is retracted to reduce space occupancy.
