[0002] The soil tiller mainly consists of an electric motor, reduction gears, a traveling mechanism, a tillering gear, a rotating shaft, and a depth adjustment mechanism. The electric motor provides power and connects to the reduction gear shaft via a coupling. The working parts consist of a cutter head and a vertical tillering gear, divided into two groups, driven by the reduction gears. The depth adjustment mechanism comprises a handle, sprockets, and a chain; the tillering depth is adjusted by changing the height of the frame.

[0003] Existing loosening gear discs are all fitted and fixed on the outer circumference of the rotating shaft, and the size of the loosening gear disc is relatively fixed, which makes it impossible to adjust the rotation radius of the loosening gear disc, making it unsuitable for loosening soil at different depths.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an agricultural soil loosening machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an agricultural soil loosening machine, comprising a rotating shaft and several soil loosening toothed discs, wherein the soil loosening toothed discs include several toothed discs 1 and 2 arranged at intervals, wherein each toothed disc 1 includes a wheel body 1 and several soil loosening teeth 1, and each toothed disc 2 includes a wheel body 2 and several soil loosening teeth 2. The wheel body 1 is fixedly connected to the outer peripheral wall of the rotating shaft, and the wheel body 2 is slidably connected to the outer peripheral wall of the rotating shaft. On the same side of the wheel body 1 and the soil loosening teeth 1, and on the same side of the wheel body 2 and the soil loosening teeth 2, a telescopic rod 1 is provided. The soil loosening teeth 1 and the soil loosening teeth 2 are respectively detachably connected to the side wall of the telescopic rod 1. Each wheel body 1 and the wheel 2 is fixedly connected to a telescopic rod 2 perpendicular to the telescopic rod 1.

[0007] The present invention is further configured such that: the telescopic rod includes a connecting pipe and a connecting rod arranged coaxially, the connecting pipe is fixedly connected to the side wall of the wheel body, and the loosening tooth is detachably connected to the side wall of the connecting rod.

[0008] The present invention is further configured such that: a fixing member is provided on the outer wall of the connecting pipe, the fixing member includes a wing bolt, and a threaded hole is provided on the outer wall of the connecting pipe, the threaded hole matching the wing bolt.

[0009] The present invention is further configured such that: a threaded column is fixedly connected to the side wall of the connecting rod one, and threaded grooves for threaded connection with the threaded column are provided on the side walls of the loosening teeth one and the loosening teeth two.

[0010] The present invention is further configured such that: the telescopic rod 2 includes a connecting pipe 2 and a connecting rod 2 arranged coaxially, the connecting pipe 2 is fixedly connected to the side wall of the wheel body 1, and the connecting rod 2 is fixedly connected to the side wall of the wheel body 2.

[0011] The present invention is further configured such that: a positioning element is provided on the outer wall of the second connecting pipe, the positioning element includes a second wing bolt, and a second threaded hole is provided on the outer wall of the second connecting pipe, the second threaded hole matching the second wing bolt.

[0012] The present invention is further configured such that: the first connecting pipe and the second connecting pipe are respectively welded to the first wheel body.

[0013] The present invention is further configured such that both the first and second loosening teeth are made of alloy steel.

[0014] In summary, this utility model has the following beneficial effects: When the telescopic rods on gear disc one and gear disc two are extended respectively, the extension of the telescopic rods drives the loosening teeth one or two to move. At this time, the loosening teeth one moves away from the wheel body one, and the loosening teeth two move together with the loosening teeth, thereby increasing the turning radius of gear disc one and gear disc two respectively. At this time, the loosening teeth one and loosening teeth two are used for loosening soil, which can be used in some situations where the loosening depth is relatively deep. Thus, by extending and retracting the telescopic rod one, it can be used to adjust gear disc one or the telescopic gear disc two. The rotation radius is adjusted so that either toothed disc one or toothed disc two can be used for different soil loosening depths. When one of the loosening teeth is damaged during the loosening process, it can be partially replaced by disassembling the damaged tooth, without the need for overall replacement. When the telescopic rod two is extended and retracted, it drives wheel two to slide on the outer circumference of the shaft. At this time, the distance between wheel one and wheel two can be adjusted, and the distance between toothed disc one and toothed disc two can be adjusted by extending and retracting the telescopic rod two.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] An agricultural soil loosening machine, such as Figure 1 , Figure 2 and Figure 4As shown, the device includes a motor, a reduction gear, a traveling mechanism, a depth adjustment mechanism, a rotating shaft 1, and several loosening gear discs. Each loosening gear disc includes several spaced-apart gear discs 21 and 22. The size and shape of gear disc 21 are the same as those of gear disc 22. Gear disc 21 includes a wheel body 211 and several loosening teeth 212. When the telescopic rod 1 is in the retracted state, the wheel body 211 and the loosening teeth 212 are in contact with each other. Gear disc 22 includes a wheel body 221 and several loosening teeth 222. The wheel body 221 and the several loosening teeth 222 are also spaced-apart. The design is detachable. Wheel body 1 211 is fixed to the outer peripheral wall of rotating shaft 1 by screws, while wheel body 221 is slidably connected to the outer peripheral wall of rotating shaft 1. A telescopic rod 1 is provided on the same side of wheel body 1 211 and soil loosening gear 1 212, and on the same side of wheel body 221 and soil loosening gear 222. Soil loosening gear 1 212 and soil loosening gear 222 are detachably connected to the side wall of telescopic rod 1. Both wheel body 1 211 and wheel body 221 are equipped with telescopic rod 2 perpendicular to telescopic rod 1. When the telescopic rod 1 on gear disc 1 21 and gear disc 2 22 is extended respectively, the telescopic rod 1... When extended, the first loosening tooth 212 or the second loosening tooth 222 moves. At this time, the first loosening tooth 212 moves away from the first wheel 211, while the second loosening tooth 222 moves in the same direction, increasing the rotation radius of the first and second gear discs 21 and 22 respectively. The first and second loosening teeth 212 and 222 are then used for loosening soil, suitable for situations requiring deeper loosening. The extension rod 1 can be used to adjust the rotation radius of the first or second gear disc 22, thus adapting the gear disc 21 or the second gear disc 22 to different applications. When used at different soil loosening depths, if one of the loosening teeth 212 or 222 is damaged during the loosening process, the damaged loosening tooth 212 or 222 can be disassembled to partially replace the tooth disc 21 or 222, without requiring a complete replacement. When the telescopic rod 2 is extended and retracted, the wheel 221 slides on the outer peripheral wall of the rotating shaft 1. At this time, the distance between the wheel 211 and the wheel 221 can be adjusted, and the distance between the tooth disc 21 and the tooth disc 22 can be adjusted by extending and retracting the telescopic rod 2.

[0023] like Figure 2 and Figure 3As shown, the telescopic rod includes a connecting pipe 31 and a connecting rod 32 arranged coaxially. The connecting pipe 31 is welded to the side wall of the wheel body 211, which can improve the connection strength and stability of the connecting pipe 31 to the wheel body 211. The loosening gear 212 is detachably connected to the side wall of the connecting rod 32. The outer wall of the connecting pipe 31 is provided with a fixing component, including a wing bolt 41. The outer wall of the connecting pipe 31 has a threaded hole 42, which matches the wing bolt 41. When it is necessary to increase the rotation radius of the gear 21 or the gear 22, the connecting rod 32 is slidable to make it slide inside the connecting pipe 31. When the connecting rod 32 slides, it drives the loosening gear 212 to move away from the wheel body 211. Then, the wing bolt 41 passes through the threaded hole 42, so that one end of the wing bolt 41 abuts against the connecting rod 32. The outer wall is fixed to increase the rotation radius of gear 21 or gear 22, which can be used for applications with deeper soil loosening. When it is necessary to reduce the rotation radius of gear 21 or gear 22, the connecting rod 32 is slidable within the connecting pipe 31. When the connecting rod 32 slides, it drives the loosening tooth 212 to move closer to the wheel body 211. Then, the wing bolt 41 passes through the threaded hole 42, and one end of the wing bolt 41 is pressed against the outer wall of the connecting rod 32 to fix it, thereby reducing the rotation radius of gear 21 or gear 22. This can be used for applications with shallower soil loosening. When one of the loosening teeth 212 or loosening tooth 222 is damaged, the damaged loosening tooth 212 or loosening tooth 222 can be disassembled to partially replace gear 21 or gear 22.

[0024] like Figure 2 and Figure 3 As shown, a threaded post 51 is welded to the side wall of connecting rod 32. Threaded grooves 52 for threaded connection with the threaded post 51 are provided on the side walls of loosening teeth 212 and 222. When gear discs 21 and 22 loosen soil, the threaded post 51 on the telescopic rod of gear disc 21 is threaded into the threaded groove 52 of loosening teeth 212, and the threaded post 51 on the telescopic rod of gear disc 22 is threaded into the threaded groove 52 of loosening teeth 222. When it is necessary to replace one of the loosening teeth 212 or 222, the loosening teeth 212 or 222 are rotated respectively, so that the threaded grooves 52 of loosening teeth 212 or 222 gradually detach from the outer peripheral wall of the threaded post 51, thereby completing the disassembly of loosening teeth 212 or 222.

[0025] like Figure 2 and Figure 4As shown, the telescopic rod 2 includes a connecting pipe 2 61 and a connecting rod 2 62 arranged coaxially. The connecting pipe 2 61 is welded to the side wall of the wheel body 1 211, improving the connection strength and stability of the connecting pipe 2 61 to the wheel body 1 211. The connecting rod 2 62 is welded to the side wall of the wheel body 2 221. A positioning component is provided on the outer wall of the connecting pipe 2 61, including a wing bolt 2 71. A threaded hole 2 72 is opened on the outer wall of the connecting pipe 2 61, and the threaded hole 2 72 matches the wing bolt 2 71. When it is necessary to adjust the distance between the gear disc 1 21 and the gear disc 2 22, the connecting rod 2 62 is slidable, causing it to slide within the connecting pipe 2 61. When the connecting rod 2 62 slides, it drives the gear disc 2 22 to move. Then, the wing bolt 71 passes through the threaded hole 72, so that one end of the wing bolt 71 abuts against the outer wall of the connecting rod 62, fixing the connecting rod 62 inside the connecting pipe 61. The telescopic rod 2 is then used to adjust the distance between the toothed disc 21 and the toothed disc 22, which can adapt to different soil conditions and operational needs. A smaller distance between the toothed disc 21 and the toothed disc 22 can loosen the soil better and improve the loosening effect, but may increase the load on the machine. A larger distance between the toothed disc 21 and the toothed disc 22 can reduce the load on the machine, but may reduce the loosening effect. Therefore, it is necessary to select an appropriate blade spacing according to the specific situation to achieve the best loosening effect.

[0026] like Figures 1 to 4 As shown, both loosening teeth 1 (212) and loosening teeth 2 (222) are made of alloy steel, while telescopic rods 1 and 2 are made of stainless steel. Alloy steel has the characteristics of high strength and wear resistance, which reduces the wear of loosening teeth 1 (212) and loosening teeth 2 (222) when they loosen the soil, and allows them to withstand greater loads, thus increasing their service life. Stainless steel has the characteristics of corrosion resistance and high strength, which reduces the corrosion of telescopic rods 1 and 2 by the soil when they enter the soil, thus increasing their service life.
