[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. 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.

[0022] This utility model embodiment provides a lawnmower with a rotatable angle, such as Figure 1-5 As shown, the rotatable lawnmower includes: a base 1; a motor 2 mounted on the base 1; a mowing disc 3 fixedly mounted on the output shaft of the motor 2 for cutting weeds; and an adjustment mechanism mounted on the base 1 and the motor 2 for adjusting the angle of the mowing disc 3.

[0023] In this embodiment, when the worker is harvesting weeds, the motor 2 is started to drive the mowing disc 3 to rotate. The rotating mowing disc 3 can clear the weeds on the ground. When clearing weeds in some inclined positions, the worker can adjust the angle of the mowing disc 3 by operating the adjustment mechanism, which makes it easier to handle weeds in some special positions. In this way, the worker does not have to stand on the inclined position, avoiding the risk of falling and injury, thus improving the safety of the worker during operation. It can also continuously cut grass in inclined positions and keep the cutting height consistent, making it more flexible and better meeting actual use needs. The entire device can harvest weeds, and the angle of the mowing disc 3 can be adjusted according to actual operation needs, so that continuous grass cutting operations can be carried out in some inclined positions, better meeting actual use needs and making it more flexible in use.

[0024] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a mounting plate 4 disposed on the base 1, a connecting block 5 hingedly disposed on the mounting plate 4; a first telescopic rod 6 hingedly disposed on the connecting block 5, a third telescopic rod 8 fixedly mounted on the output shaft of the first telescopic rod 6, the output shaft of the third telescopic rod 8 being connected to the motor 2; and a second telescopic rod 7 fixedly mounted on the mounting plate 4, the output shaft of the second telescopic rod 7 being hinged to the first telescopic rod 6.

[0025] In this embodiment, when using the adjustment mechanism, the second telescopic rod 7 is activated to push the first telescopic rod 6 upward, thereby adjusting the angle of the mowing disc 3. After adjusting the angle of the mowing disc 3, the operator starts the motor 2 to rotate the mowing disc 3. The rotating mowing disc 3 can clear weeds on the sloping ground. During the mowing process, the operator, according to the actual working conditions, activates the first telescopic rod 6 to continuously move the sloping mowing disc 3 along the sloping ground, thus enabling continuous mowing operations on the sloping ground. This way, when mowing a sloping area, it is not... The angle of the mowing disc 3 needs to be adjusted repeatedly, which allows workers to avoid standing in an inclined position, thus preventing falls and injuries and improving worker safety. During operation, workers can move the entire device according to actual needs. The horizontal position of the mowing disc 3 can be adjusted by the first telescopic rod 6, and the vertical position can be adjusted by the third telescopic rod 8. This makes it easier for the mowing disc 3 to cut weeds at different heights, making it more flexible and better meeting actual needs.

[0026] In a further preferred embodiment of the present invention, an installation block 9 is fixedly installed on the output shaft of the third telescopic rod 8, and an installation shaft 10 is rotatably installed on the installation block 9 via a damping shaft. The installation shaft 10 is fixedly connected to the motor 2, and a fixing mechanism for fixing the use angle of the installation shaft 10 is provided on the installation block 9 and the installation shaft 10.

[0027] In this embodiment, when it is necessary to adjust the angle of the mowing disc 3 to a position perpendicular to the ground, the operating fixing mechanism is disengaged from the fixing of the mounting shaft 10, and then the mowing disc 3 is rotated 90 degrees. Then, the fixing mechanism is used to fix the mounting shaft 10 again, thereby adjusting the mowing disc 3 to a position perpendicular to the ground. This makes it easier to process weeds at a position perpendicular to the ground, making it more flexible to use and better meeting the actual needs.

[0028] In a further preferred embodiment of the present invention, the fixing mechanism includes: a mounting ring 11 fixedly sleeved on the mounting shaft 10; a lead screw 12 threaded on the mounting block 9, one end of the lead screw 12 being fixedly mounted with a locking block 13; and a plurality of locking grooves 14 formed on the mounting ring 11, all of which are adapted to the locking block 13.

[0029] In this embodiment, when using the fixing mechanism, rotating the two lead screws 12 respectively drives the two locking blocks 13 to move and the corresponding two locking slots 14 to disengage. Then, the mowing disc 3 is rotated 90 degrees. At this time, the mounting shaft 10 drives the mounting ring 11 to rotate, adjusting the corresponding two locking slots 14 to one side of the two locking blocks 13. Then, rotating the two lead screws 12 in the opposite direction drives the two locking blocks 13 to move and the corresponding two locking slots 14 to connect accordingly. This fixes the mounting shaft 10 after adjustment, and thus fixes the mowing disc 3 after adjustment.

[0030] In a further preferred embodiment of this utility model, a fourth telescopic rod 15 is fixedly installed on the base 1, the output shaft of the fourth telescopic rod 15 is fixedly connected to the mounting plate 4, the fourth telescopic rod 15 is used to adjust the height of the mowing disc 3, and the bottom of the base 1 is provided with wheels for moving the base 1.

[0031] In this embodiment, the height of the mowing disc 3 can also be adjusted by the fourth telescopic rod 15 to better meet the actual functional requirements.

[0032] In a further preferred embodiment of this utility model, an operating frame 16 is provided on the base 1. The operating frame 16 is used by the operator to operate the base 1. The operating frame 16 includes a support rod 17 and an adjusting frame 18. The support rod 17 is fixedly installed on the top of the base 1. The adjusting frame 18 is assembled on the support rod 17. The adjusting frame 18 and the support rod 17 are provided with a positioning mechanism for positioning the adjusting frame 18 on the support rod 17.

[0033] In this embodiment, the operating frame 16 is used by the operator to operate the base 1. When it is necessary to adjust the overall height of the operating frame 16, the position of the adjusting frame 18 on the support rod 17 is adjusted, and then the adjusting frame 18 is positioned and fixed on the support rod 17 by the positioning mechanism. This better meets the needs of operators of different heights and makes the operation more comfortable for the operators.

[0034] In a further preferred embodiment of this utility model, the positioning mechanism includes a placement shell 19, a positioning rod 20, multiple positioning grooves 21, a stop block 22, and a spring 23. The placement shell 19 is fixedly installed on the outer wall of the adjusting frame 18, the positioning rod 20 is slidably installed on the placement shell 19, the multiple positioning grooves 21 are all formed on the support rod 17, and the multiple positioning grooves 21 are all adapted to the positioning rod 20. The stop block 22 is fixedly sleeved on the positioning rod 20, and the spring 23 is sleeved on the positioning rod 20.

[0035] In this embodiment, when using the positioning mechanism, pulling the positioning rod 20 causes the stop block 22 to compress the spring 23. As the positioning rod 20 moves, it disengages from the corresponding positioning groove 21. Then, the approximate position of the adjustment frame 18 on the support rod 17 is adjusted. After adjustment, the position of the adjustment frame 18 on the support rod 17 is finely adjusted, that is, the corresponding positioning groove 21 is adjusted to one side of the positioning rod 20. Then, the positioning rod 20 is released, and the spring 23 returns to its original position, thereby connecting the positioning rod 20 and the corresponding positioning groove 21. This fixes the adjusted frame 18 on the support rod 17, thereby adjusting the overall height of the operating frame 16 to better meet the needs of workers of different heights and make their work more comfortable.

[0036] In summary, compared with related technologies, the entire device can harvest weeds, and the angle of the mowing disc 3 can be adjusted according to actual operational needs, thus enabling continuous mowing operations at some inclined positions, better meeting actual usage requirements, and offering greater flexibility in use.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
