The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This utility model embodiment provides a convenient field weeding machine, such as Figure 1-3 As shown, the portable field weeder includes: a housing 1, a base plate fixedly installed at the bottom of the housing 1, and casters fixedly installed at the bottom of the base plate; a support column 2 rotatably mounted on the housing 1, a bracket 3 fixedly installed at the top of the support column 2, a cylinder 4 fixedly mounted on the bracket 3, a first electric push rod 5 fixedly mounted on the inner wall of the cylinder 4, a protective shell 6 fixedly mounted on the output rod of the first electric push rod 5, a motor 7 fixedly mounted on the top inner wall of the protective shell 6, a rotating shaft 8 fixedly mounted on the output shaft of the motor 7, and the rotating shaft 8 rotatably connected to the protective shell 6; a mounting sleeve 9 fixedly mounted on the rotating shaft 8 by bolts, and a blade 10 for field weeding fixedly mounted on the mounting sleeve 9; and an angle adjustment mechanism for swinging the blade 10 assembled on the housing 1.

[0019] In this embodiment, during use, the operator can easily move the device on the ground using the casters, thus conveniently moving it to the work area. When weeding is required, the first electric push rod 5 is activated to drive the protective shell 6 to move vertically. The protective shell 6 will drive the motor 7, the rotating shaft 8, the mounting sleeve 9, and the blade 10 to move vertically, allowing the blade 10 to move to a suitable working height. Then, the motor 7 is activated to drive the rotating shaft 8 to rotate, which in turn drives the blade 10 to rotate through the mounting sleeve 9, enabling the blade 10 to perform weeding work in the field. During the weeding process, the angle adjustment mechanism also needs to be activated. The angle adjustment mechanism will drive the support column 2 to rotate forward and backward on the shell 1, and the support column 2 will drive the bracket 3 to swing left and right, thus replacing the operator in swinging the rotating blade 10, effectively expanding the weeding range and effectively reducing the labor intensity of the operator.

[0020] In a further preferred embodiment of the present invention, the angle adjustment mechanism includes: a second electric push rod 11 fixedly installed on the inner wall of one side of the housing 1, a U-shaped plate 12 fixedly installed on the output rod of the second electric push rod 11, and a rack 13 fixedly installed on the U-shaped plate 12; and a gear 14 fixedly installed on the support column 2, the gear 14 meshing with the rack 13.

[0021] In this embodiment, the angle adjustment mechanism is used to swing the blade 10. When in use, the second electric push rod 11 is activated, which drives the U-shaped plate 12 to move left and right. The U-shaped plate 12 drives the rack 13 to move left and right, and the rack 13 drives the gear 14 to rotate forward and backward. The gear 14 drives the support column 2 to rotate forward and backward on the housing 1. The support column 2 drives the bracket 3 to swing left and right, and the bracket 3 drives the cylinder 4, the first electric push rod 5, the protective shell 6, the motor 7, the rotating shaft 8, the mounting sleeve 9, and the blade 10 to swing left and right. This can replace the operator in swinging the rotating blade 10, effectively expanding the weeding range and effectively reducing the labor intensity of the operator.

[0022] In a further preferred embodiment of the present invention, a limiting rod 15 is fixedly installed on the inner wall of the housing 1, and the limiting rod 15 is slidably connected to the U-shaped plate 12.

[0023] In this embodiment, the use of the limiting rod 15 can provide better support for the U-shaped plate 12, making the U-shaped plate 12 and the rack 13 more stable during horizontal movement.

[0024] In a further preferred embodiment of the present invention, a slider 16 is fixedly installed on the outer wall of the cylinder 4, and a support rod 17 is slidably installed on the slider 16. The bottom end of the support rod 17 is fixedly connected to the top of the protective shell 6.

[0025] In this embodiment, the combined use of slider 16 and support rod 17 can provide a certain support for protective shell 6. When the first electric push rod 5 drives the protective shell 6 to rise and fall vertically, the support rod 17 connected to the protective shell 6 will slide on slider 16 at the same time.

[0026] In a further preferred embodiment of the present invention, a ball bearing is provided at the bottom of the bracket 3, and the ball bearing is slidably connected to an annular groove on the housing 1.

[0027] In this embodiment, the use of the ball bearings and the annular groove together makes it less likely for the bracket 3 to wobble up and down during the swinging process. During the swinging process, the ball bearings will slide in the annular groove at the same time.

[0028] In a further preferred embodiment of the present invention, the protective shell 6 is provided with a first heat dissipation hole, and the housing 1 is provided with a second heat dissipation hole.

[0029] In this embodiment, the heat generated by the motor 7 and the second electric push rod 11 during operation can be dissipated by using the first heat dissipation hole and the second heat dissipation hole, respectively.

[0030] In a further preferred embodiment of the present invention, a handrail is fixedly installed on one side of the housing 1, and a counterweight is fixedly installed on the top of the base plate.

[0031] In this embodiment, the use of handrails makes it easy for personnel to move the weeding machine, and the use of counterweights improves the stability of the weeding machine on the ground, preventing it from tilting due to an unstable center of gravity.

[0032] In summary, compared with related technologies, this solution, through the use of casters, allows operators to easily move the weeder. The first electric push rod 5 allows for adjustment of the blade 10's height to perform different levels of weeding. The motor 7 drives the blade 10 to rotate, enabling it to remove weeds from the field. During weeding, the angle adjustment mechanism can be activated simultaneously, replacing the operator's manual swinging motion of the rotating blade 10, effectively expanding the weeding range. This solution effectively solves the technical problem of existing portable field weeders requiring continuous manual adjustment of the weeder's position, resulting in a physically demanding weeding process.

[0033] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
