[0009] A guide rod is fixed on the frame through two ear seats, a guide block is slidably matched on the guide rod, the guide block is fixedly connected to the slide block, and the guide rod is arranged parallel to the slide rail.

[0010] Wherein, protective frames are fixed on both sides of the frame, and the outer sides of the protective frames are arranged in an arc shape.

[0011] The frame is U-shaped with an opening facing one side, support rods are fixed at both ends of the opening of the frame, and the driving structure is located in the opening of the frame.

[0012] Wherein, the diameter of the loosening teeth gradually decreases in the downward direction.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0018] like Figure 1-3 As shown, a garden soil loosening device comprises a frame 1, a walking wheel 2 is installed at the front end of the frame through a wheel frame, and a handle 3 is fixedly installed on the frame; three wheel axles 4 are rotatably installed on the frame through bearings, a disc 5 is fixedly installed at the lower end of the wheel axle, and a plurality of loosening teeth 6 are fixed at the lower end of the disc, and a driving structure for driving the three wheel axles to rotate synchronously is installed on the frame.

[0019] In this way, when in use, hold the handle and move the device to the position where it needs to be used. The three electric turntables of the driving structure rotate back and forth synchronously. Press the handle downward, and the loosening teeth enter the garden soil. When the turntable rotates, the loosening teeth are driven to swing back and forth to loosen the garden soil.

[0020] During the loosening process, due to the arrangement of the walking wheels, the device can be directly pushed to move, and the loosening teeth are located in the garden soil to continuously realize the loosening operation. Of course, a battery and a controller can be installed on the frame, and the controller is connected to the driving structure.

[0021] During implementation, the driving structure includes two gear shafts rotatably connected to the frame through bearings, a transmission gear 8 is fixedly mounted on the gear shaft, an end gear 9 is fixedly mounted on the upper end of the rotating shaft, and two adjacent end gears are meshed and transmitted through the transmission gears, an electric push rod 10 is fixedly mounted on the frame, the action end of the electric push rod is fixedly connected to a slider 12 through a connecting block 11, the slider is slidably matched with a slide rail 13, the slide rail is fixedly mounted on the frame, the slider is rotatably connected to a crank 14, and the crank is rotatably connected to the edge of the end gear located in the middle.

[0022] In this way, the push rod of the electric push rod is extended and retracted, and the end gear is driven by the crank to rotate less than 180 degrees, and then the power is transmitted through the meshing of the end gear and the transmission gear, so that the three discs rotate synchronously and drive the loosening teeth to loosen the soil.

[0023] The crank is rotatably connected to the edge of the end gear to form an eccentric wheel structure, which is easy to use.

[0024] During implementation, a guide rod 15 is fixed on the frame through two ear seats, a guide block 16 is slidably matched on the guide rod, the guide block is fixedly connected to the slide block, and the guide rod is arranged parallel to the slide rail, so as to guide the movement of the slide block.

[0025] During implementation, protective frames 17 are fixed on both sides of the frame, and the outer sides of the protective frames are arranged in an arc shape to avoid damage to the garden plants.

[0026] During implementation, the frame is U-shaped with an opening facing one side, support rods are fixed at both ends of the opening of the frame, and the driving structure is located in the opening of the frame, so as to shield the driving structure and avoid mechanical damage to personnel.

[0027] During implementation, the diameter of the loosening teeth gradually decreases in the downward direction, making it easier to insert the loosening teeth into the garden soil.

[0028] Specifically, it also includes a PLC controller, which is connected with a battery and an electric push rod on the frame for easy use.

[0029] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
