These weeding devices significantly improve the production efficiency of horticulture and agriculture through efficient and precise weeding technologies. However, there are still some deficiencies in the design and functions of existing weeding devices. For example, currently, the cutting tools on weeding devices are fixed and cannot be flexibly replaced, and the cutting tools can only be used for weeding, unable to simultaneously take into account tilling and weeding. The swinging direction of the cutting tools during weeding is single, resulting in a strong vibration feeling during the swinging process of the cutting tools, making the operation of the device unstable during weeding.

[0040] The driving device includes a motor 7, a transmission shaft 8, and a rotating shaft 9. The motor 7 is installed inside the driving box 6. A gear A 10 is sleeved and fixed on the output shaft of the motor 7. The transmission shaft 8 is arranged parallel and at intervals with the motor 7.

The inner ring of the positioning bearing C20 is fixedly connected to the rotating shaft 9, and the outer ring of the positioning bearing C20 is fixedly connected to the drive box 6.

[0043] The tool includes a blade A21 and two blades B22. There are four types of blade A21 in the present invention. First, the blade A21 is U-shaped, and the two corners of the U-shaped blade A21 are right angles. The left and right ends of the blade A21 are respectively detachably connected to the ends of the two rotating shafts 9 by bolts. The front and back sides of the middle part of the blade A21 are serrated, and the middle part of the blade A21 is parallel to the rotating shaft 9. Second, the blade A21 is U-shaped, and the two corners of the U-shaped blade A21 are acute angles. The left and right ends of the blade A21 are respectively detachably connected to the ends of the two rotating shafts 9 by bolts. The front and back sides of the middle part of the blade A21 are serrated, and the middle part of the blade A21 is parallel to the rotating shaft 9. Third, the blade A is V-shaped, and the left and right ends of the blade A are respectively detachably connected to the ends of the two rotating shafts by bolts. The front and back sides of the middle part of the blade A are serrated. Fourth, several right-angled corners are provided in the middle part of the blade A. The left and right ends of the blade A are respectively detachably connected to the ends of the two rotating shafts 9 by bolts. The front and back sides of one section of the blade A are serrated.

[0044] Among them, the first type of blade A21 is a general weeding tool, the second type of blade A21 is a widened weeding tool, the third type of blade A21 is a hard ground weeding tool, and the fourth type of blade A21 is a precision weeding tool.

[0045] The upper and lower ends of the blade B22 are both arc-shaped. The upper ends of the two blades B22 are respectively detachably connected to the ends of the two transmission shafts 8 by bolts. The lower ends of the two blades B22 face each other and are offset.

[0046] The blade B22 belongs to a tilling tool, which can till the land and can also perform weeding incidentally.

[0047] Working principle:

[0048] The power source 5 located at the handle 3 is connected to the motor 7 through an electric wire to provide power support for the motor 7. One end of the electric wire is connected to the power source 5, and the other end of the electric wire passes through the upper connecting cylinder 1, the lower connecting cylinder 2, the drive box 6 and is connected to the motor 7.

[0049] When weeding is mainly performed and soil loosening and tilling are performed incidentally, blade A21 is selected for use. When tilling is performed and weeding is performed incidentally, blade B22 is selected for use.

[0050] The cutter swings in the same direction: the eccentric wheel A15 and the eccentric wheel B17 are installed at the same angle to ensure that the two swing arms 12 swing synchronously. The ends of the two rotating shafts 9 are respectively connected and fixed to the left and right ends of the blade A21 by bolts. The motor 7 is started, and the output shaft of the motor 7 rotates, driving the gear A10 to rotate. Because of the meshing relationship between the gear A10 and the gear B11, the motor 7 can drive the transmission shaft 8 to rotate synchronously while rotating. When the transmission shaft 8 rotates, it drives the eccentric wheel A15 and the eccentric wheel B17 to do circular motion, thereby driving the two swing arms 12 to swing up and down. The two swing arms 12 drive the two rotating shafts 9 to swing synchronously. In this way, the motor 7 drives the blade A21 to swing in the same direction. During the up and down swinging process of the blade A21 in the same direction, the weeds are cut.

[0051] When the cutter is swinging in the same direction, the ends of the two rotating shafts 9 can also be connected and fixed to the upper ends of the two blades B22 respectively by bolts. The blade A21 can only swing in the same direction, while the blade B22 can swing synchronously or in different directions.

[0052] The tool swings in different directions: the eccentric wheel A15 and the eccentric wheel B17 are installed with a 180° gap, and the ends of the two rotating shafts 9 are respectively connected and fixed to the upper ends of the two blades B22 by bolts. The motor 7 is started, and the output shaft of the motor 7 rotates, driving the gear A10 to rotate. Because the gear A10 and the gear B11 are engaged, the motor 7 can drive the transmission shaft 8 to rotate synchronously while rotating. When the transmission shaft 8 rotates, it drives the eccentric wheel A15 and the eccentric wheel B17 to do circular motion. Because the installation angles of the eccentric wheel A15 and the eccentric wheel B17 differ by 180° at this time, the eccentric wheel A15 and the eccentric wheel B17 are in circular motion, which can drive the two blades B22 to swing in both the upward and downward directions at the same time, that is, one blade B22 swings upward and the other blade B22 swings downward, realizing the different direction swing of the two blades B22.
