[0014] Compared with existing technologies, the beneficial effects of this utility model's weeding machine are:

[0015] This utility model uses a frame as the main structure of the weed cutter, and a drive motor to move the frame. The forward direction of the frame is set towards the positive X-axis. A connecting plate is set on the front end of the frame, i.e., the end facing the positive X-axis. The weeding wheel is connected to the end of the connecting plate away from the frame. The connecting plate extends in the plane containing the X and Y axes, providing a mounting position for the weeding wheel. The axis of the weeding wheel extends in the plane containing the X and Y axes, and the axis of the weeding wheel is inclined at an angle to the X-axis, but the angle is not 90 degrees. That is, the axis of the weeding wheel is neither perpendicular nor parallel to the X-axis. The weeding wheel can also rotate around its axis. During operation, the drive mechanism drives the frame, bringing... As the weeding wheel moves in the positive X-axis direction, it inserts into the soil and rolls in contact with the ground, rotating around its axis. The digging part on the outer edge of the wheel contacts the weeds in the soil. The weeds are subjected to both the force in the plane of the X and Z axes caused by the movement of the wheel in the positive X-axis direction and the force of the wheel's tilt relative to the positive X-axis caused by its rotation around its axis. The combined force on the weeds makes them easier to dig out. Furthermore, because the wheel is tilted, its corresponding dimension in the Y-axis direction is larger, allowing for a larger area of ​​soil to be dug out in a single weeding operation, thus improving the weeding effect.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] Furthermore, although specific embodiments have been described herein with reference to them, it should be understood that these embodiments are merely examples of the principles and applications of the present invention. Therefore, it should be understood that many modifications can be made to the exemplary embodiments, and other arrangements can be designed without departing from the spirit and scope of the present invention as defined by the appended claims. It should be understood that different dependent claims and features herein can be combined in ways not used as described in the original claims. It is also understood that features described in conjunction with individual embodiments can be used in other embodiments.

[0026] To solve the above problems, such as Figure 1 and Figure 2As shown, this utility model provides a weed cutter, including a drive mechanism, a frame 1, a connecting plate 2, and a weeding wheel 3. The drive mechanism is used to drive the frame 1 to move. The connecting plate 2 is connected to the front end of the frame 1. The weeding wheel 3 is connected to the connecting plate 2. The axial direction of the weeding wheel 3 is set at an angle to the forward direction of the frame 1 in the horizontal plane, and the angle is not 90 degrees. The weeding wheel 3 is used to rotate around its axis.

[0027] In this embodiment, a frame 1 is set as the main structure of the weed cutter, and a drive motor drives the frame 1 to move. The forward direction of the frame 1 is set towards the positive X-axis. A connecting plate 2 is set on the front end of the frame 1, i.e., the end face facing the positive X-axis. The weeding wheel 3 is connected to the end of the connecting plate 2 away from the frame 1. The connecting plate 2 extends in the plane containing the X and Y axes, providing an installation position for the weeding wheel 3. The axis of the weeding wheel 3 extends in the plane containing the X and Y axes, and the axis of the weeding wheel 3 is inclined at an angle to the X-axis, but the angle is not 90 degrees. That is, the axis of the weeding wheel 3 is neither perpendicular nor parallel to the X-axis. The weeding wheel 3 can also rotate around its axis. During operation, the drive mechanism drives the frame 1. The frame 1 drives the weeding wheel 3 to move in the positive X-axis direction. During this process, the weeding wheel 3 inserts into the soil and rolls in contact with the ground, rotating around its axis. The digging part on the outer edge of the weeding wheel 3 contacts the weeds in the soil. The weeds are subjected to both the force in the plane of the X-axis and Z-axis caused by the movement of the weeding wheel 3 in the positive X-axis direction, and the force of the weeding wheel 3 tilting relative to the positive X-axis direction caused by its rotation around its axis. The two forces act on the weeds together, and the weeds are subjected to a greater force, making it easier to dig out the weeds. In addition, because the weeding wheel 3 is tilted, the corresponding size of the weeding wheel 3 in the Y-axis direction is larger, and a larger soil area can be dug in one weeding operation, improving the weeding effect.

[0028] Optionally, the weeding wheel 3 is configured such that its axial direction is adjustable in the horizontal plane.

[0029] In this embodiment, by setting the axis of the weeding wheel 3 to be adjustable in the horizontal plane, the tilt angle of the weeding wheel 3 can be adjusted, and the corresponding size of the weeding wheel 3 in the Y-axis direction can be adjusted to adjust the soil area that can be excavated in one weeding operation. The tilt angle of the weeding wheel 3 can be adjusted according to the actual land conditions to improve the weeding effect.

[0030] Specifically, the size of the weeding wheel 3 in the Y-axis direction can be set to be the same as the width of the furrow between two adjacent rows, so that weeds in a furrow can be dug out at once.

[0031] Optionally, such as Figure 3As shown, the weeder also includes a first bolt 22, a second bolt 23, and a connecting rod 31. One end of the connecting rod 31 is connected to the connecting plate 2, and the other end is perpendicularly connected to the center of the weeding wheel 3. The connecting plate 2 is horizontally arranged and has an arc-shaped through groove 21 and a first through hole. The first through hole is located at the center of the arc-shaped through groove 21. The first bolt 22 is used to press the connecting rod 31 and is connected in the first through hole. The second bolt 23 is used to press the connecting rod 31 and is connected in the arc-shaped through groove 21. The second bolt 23 is used to move within the arc-shaped through groove 21.

[0032] In this embodiment, the connecting rod 31 is perpendicularly connected to the center of the weeding wheel 3, meaning the connecting rod 31 and the weeding wheel 3 are coaxially connected. Therefore, the axial direction of the weeding wheel 3 can be adjusted by driving the connecting rod 31 to rotate in the horizontal plane. An arc-shaped through groove 21 is formed on the surface of the connecting plate 2, and a first through hole is formed at the center of the arc-shaped through groove 21. A first bolt 22 is placed in the first through hole, and a second bolt 23 is placed in the arc-shaped through groove 21. The position of the second bolt 23 can be moved arbitrarily within the arc-shaped through groove 21. Both the first bolt 22 and the second bolt 23 can press the connecting rod 31. By loosening the first bolt 22 until the connecting rod 31 can rotate around the first bolt 22, and then loosening the second bolt 23 and adjusting the position of the second bolt 23 within the arc-shaped through groove 21, the connecting rod 31 can rotate around the first bolt 22, thereby changing the tilt angle of the weeding wheel 3, making the tilt angle of the weeding wheel 3 adjustable.

[0033] Optionally, such as Figure 3 and Figure 4 As shown, the weeder also includes a fixing sleeve 41, which extends horizontally. The bottom of the fixing sleeve 41 is provided with a fixing plate 42 extending in the horizontal plane. The fixing plate 42 has a first bolt hole and a second bolt hole. The connecting rod 31 passes through the fixing sleeve 41. The first bolt 22 passes through the first bolt hole and the first through hole, and the second bolt 23 passes through the second bolt hole and the arc-shaped through groove 21.

[0034] In this embodiment, an integrated fixing sleeve 41 and fixing plate 42 are provided. The fixing plate 42 extends in the horizontal plane, and the fixing sleeve 41 is connected above the fixing plate 42 and extends in the horizontal plane. The fixing plate 42 has a first bolt hole and a second bolt hole. The first bolt 22 passes through the first bolt hole and the first through hole in sequence, and the second bolt 23 passes through the second bolt hole and the arc-shaped through groove 21 in sequence, connecting the fixing plate 42 and the fixing sleeve 41 to the connecting plate 2. The axial angle of the fixing sleeve 41 can be adjusted by adjusting the position of the second bolt 23 on the arc-shaped through groove 21. The connecting rod 31 is inserted into the fixing sleeve 41, connecting the weeding wheel 3 into the fixing sleeve 41, and then fixing it to the connecting plate 2, thereby improving the stability of the connection structure between the weeding wheel 3 and the connecting plate 2.

[0035] Specifically, a threaded hole can be opened at the top of the fixing sleeve 41, and a bolt can be screwed into the threaded hole and pressed onto the part of the connecting rod 31 located inside the fixing sleeve 41, thereby improving the stability of the connection structure between the connecting rod 31 and the fixing sleeve 41.

[0036] Optionally, such as Figure 3 As shown, the end of the connecting rod 31 away from the connecting plate 2 is provided with a rotating shaft seat 32, and the center of the weeding wheel 3 is provided with a rotating shaft. The rotating shaft is inserted into the shaft hole of the rotating shaft seat 32 and is rotatably connected to the rotating shaft seat 32.

[0037] In this embodiment, a pivot seat 32 is provided at the end of the connecting rod 31 away from the connecting plate 2. The pivot seat 32 has a shaft hole at the end facing the weeding wheel 3. The center of the weeding wheel 3 is vertically arranged on a pivot extending in the horizontal plane. The pivot is inserted into the pivot seat 32 and rotatably connected to the pivot seat 32, so that the weeding wheel 3 can rotate relative to the connecting rod 31 and the connecting plate 2 around the axis of the weeding wheel 3.

[0038] Optionally, such as Figure 2 As shown, the connecting plate 2 is provided with weeding wheels 3 on both sides in the horizontal plane.

[0039] In this embodiment, by setting weeding wheels 3 at both ends of the connecting plate 2 along the Y-axis, and both weeding wheels 3 being inclined, the two weeding wheels 3 working simultaneously expand the weeding area and improve the weeding effect.

[0040] Specifically, the connecting plate 2 is provided with two arc-shaped through grooves 21, and the concave surfaces of the two arc-shaped through grooves 21 face opposite directions. For example, the concave surfaces of the two arc-shaped through grooves 21 face the positive and negative directions of the Y-axis, respectively. The two arc-shaped through grooves 21 are arranged along the X-axis and can be connected to each other to form an S-shaped through groove, which is convenient for processing. A first through hole is opened at the center of each arc-shaped through groove 21. The two weeding wheels 3 are connected to the left and right sides of the connecting plate 2 respectively through the two arc-shaped through grooves 21 and the two first through holes.

[0041] Optionally, such as Figure 2 As shown, the front end of the frame 1 is provided with a plurality of connecting plates 2 and a plurality of weeding wheels 3 evenly distributed along its extension direction.

[0042] In this embodiment, by setting multiple connecting plates 2 and multiple weeding wheels 3 at the front end of the frame 1, the multiple connecting plates 2 are evenly distributed along the Y-axis direction, which facilitates the expansion of the weeding area of ​​the weeding machine and improves the weeding effect.

[0043] Optionally, such as Figure 1 As shown, the drive mechanism includes a motor and a wheel 5. The wheel 5 is connected to the rear end of the frame 1, and the motor is driven by the wheel 5.

[0044] In this embodiment, a wheel 5 is provided on the side of the frame 1 facing the negative direction of the X-axis. The two sides of the wheel 5 can be connected to the frame 1 by a connecting rod. A motor is provided to drive the wheel 5, which drives the wheel 5 and moves the frame 1 on the ground, so that the frame 1 can drive the weeding wheel 3 to move forward for weeding.

[0045] Optionally, such as Figure 1 As shown, an auxiliary wheel 61 is also provided below the frame 1.

[0046] In this embodiment, by setting an auxiliary wheel 61 under the frame 1, the auxiliary wheel 61 and the wheel 5 rotate together during operation, making the weed cutter move forward more smoothly.

[0047] Optionally, such as Figure 1 As shown, the lawn mower also includes a handle 62, which is connected above the frame 1 and extends to the rear of the frame 1.

[0048] In this embodiment, a handle 62 is provided on the frame 1, extending toward the negative X-axis and the positive Z-axis, making it easy for a person to grip the handle 62 and adjust the forward direction of the weed cutter.

[0049] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
