Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, and in particular to a quick corn planting soil loosening device. Background Technology

[0002] Over time, the soil used for corn planting tends to clump together, which reduces root aeration and effectively seals the roots. Loosening the soil increases the gaps between soil particles, allowing air to enter more easily and increasing root cell respiration.

[0003] According to the description in the patent application CN 218163479 U, a soil loosening device for corn planting, this utility model relates to the field of agricultural planting technology, specifically a soil loosening device for corn planting. It includes a horizontal plate and multiple rake teeth, with the rake teeth spaced apart directly below the horizontal plate. Multiple insertion holes are spaced apart on the horizontal plate. Insert plates are fixed above each of the rake teeth, with one end of each insert plate passing through a insertion hole and extending upwards. Each insert plate has a hole on one side. An inner cavity is formed inside the horizontal plate, penetrating the multiple insertion holes. A fixing mechanism is provided between the insertion holes and the inner cavity. An upper plate is provided above the horizontal plate, and adjustment mechanisms are connected to both sides of the upper plate and the horizontal plate. When using this soil loosening device, the mounting plate only needs to be installed on a tractor, and the tractor can then move the multiple rake teeth within the soil to loosen the soil.

[0004] Regarding the above description, the applicant believes the following problems exist: When the mounting plate is attached to the tractor, the tractor can drive multiple rake teeth to move through the soil to loosen it. The fixing mechanism can secure the rake teeth to the cross plate; if a rake tooth is damaged, it can be removed and replaced with a new one. However, because different soils have different physical and mechanical properties, the spacing between the rake teeth needs to be adjusted to adapt. But this device cannot quickly adjust the spacing between the rake teeth and cannot be adjusted according to specific soil conditions, resulting in uneven soil loosening. Utility Model Content

[0005] To overcome the problem of uneven soil loosening caused by the inability to quickly adjust the spacing between the rake teeth and the inability to adjust according to the specific soil conditions.

[0006] The technical solution of this utility model is as follows: a quick corn planting soil loosening device, including a mobile vehicle; it also includes an installation plate and an adjusting soil loosening component. The installation plate is provided on the right side of the mobile vehicle, and the installation plate has moving wheels on both sides. A motor is fixedly connected to the installation plate, and a rotating disk is fixedly connected to the output end of the motor. A connecting belt is driven to the rotating disk, and a rotating disk is driven to the end of the connecting belt away from the rotating disk. A threaded rod is fixedly connected to one end of the rotating disk, and a sliding block is threadedly connected to the threaded rod. A moving plate is fixedly connected to the sliding block. A limit rail is fixedly connected to the end of the installation plate away from the motor. A sliding plate is slidably connected to the installation plate, and an adjusting soil loosening component is provided on the sliding plate.

[0007] Preferably, the movable plate is provided with radial grooves, and the movable plate is slidably connected to the sliding block through the radial grooves.

[0008] Preferably, when the sliding block moves closer to the motor, the sliding plates inside the sliding block move closer to each other, and vice versa.

[0009] Preferably, the movable plate is provided with a sliding groove, and the movable plate is slidably connected to the limiting rail through the sliding groove.

[0010] Preferably, when the first rotating disk rotates, the connecting belt will provide power to the second rotating disk.

[0011] Preferably, the soil loosening and adjusting assembly includes a second motor, which is fixedly connected to the top of the mounting plate. A screw is fixedly connected to the output end of the second motor, and a limit rod is fixedly connected to the bottom of the mounting plate. A sliding plate is threaded onto the screw, and a sliding sleeve is fixedly connected to the upper end of the sliding plate away from the first motor. A sliding rod is slidably connected inside the sliding sleeve, and a rake tooth is fixedly connected to one end of the sliding rod. A protrusion is fixedly connected to the lower end of the sliding rod away from the rake tooth.

[0012] Preferably, the skateboard has a groove, and the protrusion is slidably connected to the inside of the skateboard through the groove.

[0013] The beneficial effects of this utility model are as follows: The device drives a rotating disk to rotate via a drive motor, which in turn causes the rotating disk to rotate via a connecting belt. This causes the sliding block on the threaded rod to move, ultimately allowing the sliding plate to move closer to the moving plate to adjust the spacing of the soil loosening components. On the one hand, the spacing of the rake teeth can be flexibly adjusted according to the actual soil conditions, making the rake teeth work more precisely and greatly improving the soil loosening effect. On the other hand, the rake tooth adjustment operation can be completed quickly, saving time and manpower, greatly enhancing the convenience of using the device and improving work efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a quick corn planting soil loosening device, including a mobile vehicle 1; it also includes a mounting plate 21 and an adjusting soil loosening component. The mounting plate 21 is located on the right side of the mobile vehicle 1, and moving wheels 22 are located on both sides of the mounting plate 21. A motor 23 is fixedly connected to the mounting plate 21, and a rotating disk 24 is fixedly connected to the output end of the motor 23. A connecting belt 25 is driven to the rotating disk 24, and a rotating disk 26 is driven to the end of the connecting belt 25 away from the rotating disk 24. A threaded rod 27 is fixedly connected to one end of the rotating disk 26, and a sliding block 28 is threadedly connected to the threaded rod 27. A moving plate 29 is fixedly connected to the sliding block 28. A limit rail 210 is fixedly connected to the end of the mounting plate 21 away from the motor 23, and a sliding plate 211 is slidably connected to the mounting plate 21. A soil loosening component is located on the sliding plate 211, which drives the connecting belt 25 on the rotating disk 24 via the motor 23. Rotating on the rotating disk 26, the rotating disk 26 will drive the sliding block 28 on the threaded rod 27 to move. When the sliding block 28 drives the moving plate 29 to move closer to the motor 23, the sliding plates 211 gradually move closer to each other as the moving plate 29 moves, thereby adjusting the distance between the soil loosening components.

[0022] Please see Figure 2-4In this embodiment, the movable plate 29 is provided with radial grooves, and the sliding plate 211 is slidably connected to the sliding block 28 through the radial grooves. The movable plate 29 facilitates the control of the sliding plates 211 moving closer or further apart. When the sliding block 28 moves closer to the motor 23, the sliding plates 211 in the sliding block 28 move closer together, and vice versa. The sliding plates 211 facilitate the adjustment of the distance between the rake teeth 37 on the sliding rod 36. The movable plate 29 is provided with grooves, and the movable plate 29 is slidably connected to the limiting rail 210 through the grooves. The limiting rail 210 facilitates the restriction of the sliding direction of the movable plate 29. When the rotating disk 24 rotates, the connecting belt 25 provides power to the rotating disk 26. The rotating disk 24 facilitates the provision of power to the rotation of the connecting belt 25.

[0023] Please see Figure 5 In this embodiment, the soil loosening adjustment assembly includes a second motor 31, which is fixedly connected to the top of the mounting plate 21. A screw 32 is fixedly connected to the output end of the second motor 31, and a limit rod 34 is fixedly connected to the bottom of the mounting plate 21. A sliding plate 33 is threaded onto the screw 32. A sliding sleeve 35 is fixedly connected to the upper end of the sliding plate 211 away from the first motor 23. A sliding rod 36 is slidably connected inside the sliding sleeve 35. A rake tooth 37 is fixedly connected to one end of the sliding rod 36, and a protrusion 38 is fixedly connected to the other end of the sliding rod 36 away from the rake tooth 37. The presence of the rake tooth 37 facilitates soil loosening. A groove is provided on the sliding plate 33, and the protrusion 38 is slidably connected inside the sliding plate 33 through the groove. The presence of the sliding plate 33 facilitates the sliding of the sliding rod 36 on the sliding block 28 within the sliding sleeve 35.

[0024] During operation, the drive motor 23 drives the connecting belt 25 on the rotating disk 24 to rotate on the rotating disk 26. The rotating disk 26 drives the sliding block 28 on the threaded rod 27 to move. When the sliding block 28 drives the moving plate 29 to move closer to the motor 23, the sliding plate 211 gradually moves closer to each other as the moving plate 29 moves. At this time, the sliding plate 211 drives the protrusion 38 on the sliding rod 36 inside the sliding sleeve 35 to slide in the sliding plate 33, thereby adjusting the distance between the rake teeth 37. The motor 21 drives the sliding plate 33 on the screw 32 to slide on the limiting rod 34, so that the sliding plate 33 drives the sliding rod 36 on the protrusion 38 to slide in the sliding sleeve 35, thereby adjusting the height of the rake teeth 37. The moving vehicle 1 drives the moving wheels 22 at both ends of the mounting plate 21 to move on the ground, so that the rake teeth 37 can loosen the soil.

[0025] Through the above steps, drive motor 23 drives rotating disk 24, causing the connecting belt 25 connected to rotating disk 24 to rotate on rotating disk 26, which in turn drives rotating disk 26 to rotate. The rotation of rotating disk 26 causes sliding block 28 on threaded rod 27 to move. When sliding block 28 moves moving plate 29 closer to motor 23, sliding plate 211 gradually moves closer to moving plate 29, thereby adjusting the distance between the soil loosening components. This allows for adjustment of the spacing of rake teeth 37 according to specific soil conditions, improving soil loosening effect, and also enables quick adjustment of rake teeth 37, enhancing the ease of use of the device.
