Description

Technical Field

[0001] This utility model relates to the field of soil loosening devices, specifically a soil loosening device for crop planting. Background Technology

[0002] In agricultural production, soil turning is usually done manually or by livestock using tools such as hoes and plows. Soil turning and loosening before planting breaks up and loosens the soil, which helps crops absorb nutrients and water better and promotes root and stem growth. It can be said to be a very important agricultural operation in crop planting.

[0003] In practical use, existing soil loosening devices for crop cultivation generally turn the soil using the rake teeth on the loosening frame. During the turning process, large clumps of soil easily stick to the rake teeth and are difficult to remove. Continuing to turn the soil will affect the turning effect, and the rake teeth need to be cleaned before operation, which is time-consuming, affects the use effect, and is inconvenient. Therefore, there is an urgent need to improve the technology of the structure of soil loosening devices for crop cultivation to improve this equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a soil loosening device for crop planting. By setting up a brush plate, when turning the soil, the controller controls the servo motor to work, and the transmission mechanism drives the brush plate to rotate. When loosening the soil as the rake teeth rotate, the brush plate can sweep the side ends of the rake teeth, which can remove large pieces of soil adhering to the rake teeth to a certain extent, thereby enhancing the soil loosening effect of the rake teeth during use and avoiding the obstruction of the work process due to excessive soil adhering to the rake teeth, thus solving the problems mentioned in the background art in the current market.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil loosening device for crop planting, comprising a connecting rod, a fixed frame fixedly connected to the bottom end of the connecting rod, a soil loosening frame at the bottom of the fixed frame, a moving mechanism within the fixed frame driving the soil loosening frame to move back and forth laterally, a protective plate fixedly connected to the inner end of the fixed frame near the soil loosening frame, an opening groove at the bottom end of the soil loosening frame, multiple grooves within the soil loosening frame near the top end of the opening groove, a drive shaft rotatably connected within the opening groove, multiple rake teeth fixedly connected to the outer end of the drive shaft, a servo motor fixedly connected to the right end of the drive shaft, a rotating shaft rotatably connected to the inside of each groove, multiple brush plates fixedly connected to the outer end of the rotating shaft, brush plates on both the left and right sides of each groove, and the drive shaft and rotating shaft rotating together within the soil loosening frame via a transmission mechanism.

[0006] Preferably, the bottom end of the fixing frame is provided with two sliding grooves, and a slider is slidably connected in each of the sliding grooves. The bottom end of the slider is fixedly connected to the soil loosening frame, and a threaded rod is threadedly connected to the slider. A drive motor is fixedly connected to the right end of the threaded rod.

[0007] Preferably, the threaded rod has a unidirectional pattern at its outer end, and the threaded rod extends to the outside of the fixing frame and forms a rotatable connection with the fixing frame.

[0008] Preferably, the brush plate is attached to the side end of the rake teeth, and the brush bristles are glued to the end of the brush plate near the rake teeth. The material of the brush bristles on the brush plate is polypropylene.

[0009] Preferably, the soil loosening frame has an internal mounting groove, in which a drive gear and a driven gear are rotatably connected. The drive shaft passes through the mounting groove and extends to the outside of the soil loosening frame, forming a rotatable connection with the soil loosening frame. The drive gear is fixedly connected to the outside of the drive shaft. The rotating shaft also has a mounting groove and extends to the outside of the soil loosening frame. The driven gear is fixedly connected to the outside of the rotating shaft. The outer ends of the drive gear and the driven gear are meshed with a toothed belt.

[0010] Preferably, the driving gear and the driven gear are the same size, and the tooth pitch at the outer ends of the driving gear and the driven gear is also equal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by incorporating a brush plate, utilizes a controller to operate a servo motor during soil turning. The servo motor drives a transmission shaft, which in turn rotates the drive gear and rake teeth to turn the soil. Simultaneously, the rotation of the drive gear drives the driven gear via a toothed belt, which in turn rotates the shaft, thus rotating the brush plate. As the rake teeth rotate to loosen the soil, the rotating brush plate brushes the sides of the rake teeth, effectively removing large clumps of soil adhering to them. This enhances the soil-loosening effect of the rake teeth and prevents them from becoming stuck with excessive soil, which could hinder the work process. Furthermore, the rotating brush plate further improves the cleaning effect compared to a stationary brush plate, making it convenient to use.

[0012] This invention features a moving mechanism that uses a controller to operate a drive motor. The drive motor rotates a threaded rod, which, through a threaded connection with a slider, causes the slider to slide laterally within a groove. This allows the loosening frame to move back and forth within a fixed frame, thus expanding the tilling area of ​​the rake teeth to some extent. A protective plate connected to the inner end of the fixed frame provides shock absorption and resilience, preventing strong impacts between the loosening frame and the fixed frame. Furthermore, the fixed frame, positioned above the loosening frame, effectively blocks the soil turned out by the rake teeth, preventing soil from splashing during operation and thus improving the overall performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 4This utility model provides a technical solution: a soil loosening device for crop planting, including a connecting rod 1, a fixed frame 2 fixedly connected to the bottom end of the connecting rod 1, a soil loosening frame 3 provided at the bottom of the fixed frame 2, a moving mechanism inside the fixed frame 2 driving the soil loosening frame 3 to move back and forth laterally, a protective plate 8 fixedly connected to the inner end of the fixed frame 2 near the soil loosening frame 3, an opening groove 9 opened at the bottom end of the soil loosening frame 3, a plurality of grooves 10 opened inside the soil loosening frame 3 near the top end of the opening groove 9, a drive shaft 11 rotatably connected inside the opening groove 9, a plurality of rake teeth 12 fixedly connected to the outer end of the drive shaft 11, a servo motor 17 fixedly connected to the right end of the drive shaft 11, a rotating shaft 13 rotatably connected inside each groove 10, a plurality of brush plates 14 fixedly connected to the outer end of the rotating shaft 13, a brush plate 14 provided on both the left and right sides of each groove 10, and the drive shaft 11 and the rotating shaft 13 rotating together inside the soil loosening frame 3 through a transmission mechanism.

[0017] By setting up the brush plate 14, during soil turning, the controller controls the servo motor 17 to work. The servo motor 17 drives the transmission shaft 11 to rotate, which in turn drives the drive gear 16 and the rake teeth 12 to rotate for soil turning. At the same time, the rotation of the drive gear 16 drives the driven gear 18 to rotate through the toothed belt 19, which in turn drives the rotating shaft 13 to rotate, thereby driving the brush plate 14 to rotate. When the rake teeth 12 rotate to loosen the soil, the rotating brush plate 14 can brush the side ends of the rake teeth 12, which can remove large pieces of soil adhering to the rake teeth 12 to a certain extent, enhancing the soil loosening effect of the rake teeth 12 during use, and preventing the work process from being hindered by too much soil adhering to the rake teeth 12. Moreover, the rotating brush plate 14 can further improve the cleaning effect compared to the stationary brush plate 14, and is convenient to use.

[0018] Please see Figures 2 to 3 The bottom of the fixed frame 2 is provided with two sliding grooves 4, and a slider 5 is slidably connected in each of the sliding grooves 4. The bottom of the slider 5 is fixedly connected to the soil loosening frame 3. A threaded rod 6 is threadedly connected inside the slider 5. A drive motor 7 is fixedly connected to the right end of the threaded rod 6. The texture of the outer end of the threaded rod 6 is unidirectional. The threaded rod 6 extends to the outside of the fixed frame 2 and forms a rotatable connection with the fixed frame 2. The brush plate 14 is attached to the side end of the rake tooth 12. The brush bristles are glued to the end of the brush plate 14 near the rake tooth 12. The material of the brush bristles on the brush plate 14 is polypropylene. By setting the material of the brush bristles on the brush plate 14 to polypropylene, polypropylene has high hardness, low absorption, and is resistant to acids and alkalis, which can effectively remove large pieces of soil adhering to the rake tooth 12.

[0019] Please see Figure 2 and Figure 4The soil loosening frame 3 has an installation groove 15 inside. A drive gear 16 and a driven gear 18 are rotatably connected in the installation groove 15. The drive shaft 11 passes through the installation groove 15 and extends to the outside of the soil loosening frame 3. The drive shaft 11 and the soil loosening frame 3 are rotatably connected. The drive gear 16 is fixedly connected to the outside of the drive shaft 11. The rotating shaft 13 is also installed in the installation groove 15 and extends to the outside of the soil loosening frame 3. The driven gear 18 is fixedly connected to the outside of the rotating shaft 13. The outer ends of the drive gear 16 and the driven gear 18 are meshed with a toothed belt 19. The drive gear 16 and the driven gear 18 are the same size, and the tooth pitch at the outer ends of the drive gear 16 and the driven gear 18 is also equal.

[0020] The servo motor 17 drives the transmission shaft 11 to rotate, which in turn drives the drive gear 16 and the rake teeth 12 to rotate. The rotation of the drive gear 16 can drive the driven gear 18 to rotate via the toothed belt 19, which in turn drives the rotating shaft 13 to rotate, thereby driving the brush plate 14 to rotate. This removes large pieces of soil adhering to the rake teeth 12, enhancing the soil loosening effect of the rake teeth 12 during use.

[0021] Working principle: When using this soil loosening device for crop planting, firstly, during soil turning, the servo motor 17 is controlled by the controller to work. The servo motor 17 drives the transmission shaft 11 to rotate, which in turn drives the drive gear 16 and the rake teeth 12 to rotate for soil turning. At the same time, the rotation of the drive gear 16 drives the driven gear 18 to rotate through the toothed belt 19, which in turn drives the rotating shaft 13 to rotate, thereby driving the brush plate 14 to rotate. When loosening the soil as the rake teeth 12 rotates, the brush plate 14 can rotate to brush the side of the rake teeth 12, which can remove large pieces of soil adhering to the rake teeth 12 to a certain extent, enhancing the soil loosening effect of the rake teeth 12 during use, and avoiding the obstruction of the work process due to excessive soil adhering to the rake teeth 12. Moreover, the rotating brush plate 14 can further improve the cleaning effect compared to the stationary brush plate 14. Meanwhile, the controller controls the drive motor 7 to work, and the moving mechanism drives the loosening frame 3 to move back and forth within the fixed frame 2, thereby widening the soil turning area of ​​the rake teeth 12 to a certain extent. Because the inner end of the fixed frame 2 is connected to the protective plate 8, the protective plate 8 has a certain shock absorption and resilience, avoiding a large impact between the loosening frame 3 and the fixed frame 2. Moreover, the fixed frame 2 is located above the loosening frame 3, which can block the soil turned out by the rake teeth 12, preventing soil from splashing when the rake teeth 12 are working and causing safety hazards, thus improving the use effect.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
