[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] like Figure 1-3 As shown, the embodiment of the present invention provides an adjustable lawn mower head, including a hand-held rod 1, an adjustment component 2 is fixedly provided at one end of the hand-held rod 1, a connecting disk 3 is provided at the end of the adjustment component 2 away from the hand-held rod 1, a rotating disk 31 is rotatably provided at the lower end of the connecting disk 3, a plurality of mowing blades 32 are fixedly provided on the outer wall of the rotating disk 31, a plurality of arc grooves 33 are provided on the lower surface of the connecting disk 3, the arc grooves 33 are arranged around the rotating disk 31, and a slider 34 is slidably provided in the arc grooves 33, and a push rod 35 is fixedly provided at the end of the slider 34 away from the arc grooves 33;

[0026] A plurality of transmission rods 36 are further provided on the outer wall of the rotating disc 31 . The transmission rods 36 cooperate with the slider 34 and are located above the mowing blades 32 .

[0027] Among them, the adjustment component 2 is used to adjust the angle of the machine head, which is convenient for cutting grass at different angles. The lower end of the connecting disk 3 is used to set the rotating disk 31 and the mowing blade 32. An arc groove 33 is set on the lower surface of the connecting disk 3. A slider 34 is slidingly set in the arc groove 33. A push rod 35 is fixedly set at the end of the slider 34 away from the arc groove 33. A transmission rod 36 is set on the outer wall of the rotating disk 31. When the rotating disk 31 rotates and drives the mowing blade 32 to mow the grass, the rotating disk 31 drives the transmission rod 36 to rotate, so that the transmission rod 36 acts on the slider 34, and transmits the force to the slider 34 to enable it to move in the arc groove 33. The movement of the slider 34 drives the push rod 35 below the slider 34 to move, so that the push rod 35 is moved to clean hard objects on the ground to prevent the mowing blade 32 from hitting hard objects and causing damage to the machine.

[0028] like Figure 2 As shown, the adjustment assembly 2 includes a first fixing frame 21 and two second fixing frames 22 , and the two second fixing frames 22 are fixedly arranged on the upper surface of the connecting plate 3 .

[0029] The adjustment assembly 2 includes a first fixing frame 21 and two second fixing frames 22 , and the second fixing frames 22 are fixed on the upper surface of the connecting plate 3 to facilitate the adjustment of the machine head between different angles.

[0030] like Figure 2 As shown, the first fixing frame 21 is rotatably arranged on opposite surfaces of the two second fixing frames 22 via a screw rod 23 .

[0031] The first fixing frame 21 is fixed between the two second fixing frames 22 by means of a screw 23 , which is easy to operate and can quickly adjust the angle of the first fixing frame 21 relative to the second fixing frames 22 .

[0032] like Figure 2 As shown, a nut 24 is provided at one end of the screw rod 23 away from the first fixing frame 21 , and the nut 24 cooperates with the screw rod 23 .

[0033] A nut 24 is provided at one end of the screw rod 23 away from the first fixing frame 21 , and the nut 24 facilitates locking the first fixing frame 21 after adjusting the angle between the first fixing frame 21 and the second fixing frame 22 .

[0034] like Figure 1 As shown, a flexible shaft 4 is installed inside the hand-held rod 1, and one end of the flexible shaft 4 passes through the connecting disk 3 and is rotatably connected to the rotating disk 31.

[0035] Among them, through the use of the flexible shaft 4, when the angle of the head is adjusted, the flexible shaft 4 can still continue to transmit power and connect with the rotating disk 31, avoiding the situation where power transmission cannot be performed due to the adjustment of the head angle.

[0036] like Figure 1 As shown, the end of the flexible shaft 4 away from the rotating disc 31 is connected to the motor 5.

[0037] The motor 5 is used to provide power support for the rotation of the rotating disc 31 .

[0038] like Figure 1 As shown, the connecting disk 3 is a disk with a certain inclination.

[0039] Among them, the connecting disk 3 is set to a circular disk with a certain inclination. After the transmission rod 36 applies a force to the slider 34 to slide in the arc groove 33, due to the angle of inclination, the slider 34 will still return to its original position after sliding, so that the slider 34 can continue to slide in the arc groove 33 under the action of the transmission rod 36. At the same time, the connecting disk 3 is set to a circular disk with a certain inclination angle. When the transmission rod 36 acts on the slider 34, the transmission rod 36 can continue to rotate with the rotating disk 31, preventing the transmission rod 36 from getting stuck next to the slider 34.

[0040] like Figure 3 As shown, the diameter of the mowing blade 32 is smaller than the distance from the push rod 35 to the rotating disc 31 .

[0041] The diameter of the mowing blade 32 is set to be smaller than the distance between the push rod 35 and the rotating disc 31 to avoid the mowing blade 32 having an excessively long diameter acting on the push rod 35 and causing damage to the push rod 35 .

[0042] The working principle of this embodiment is as follows: when the angle of the machine head needs to be adjusted, the nut 24 is loosened to adjust the angle of the first fixing frame 21 relative to the second fixing frame 22, and then the nut 24 is tightened to complete the adjustment of the machine head angle, and the motor 5 is started. The motor 5 transmits power to the rotating disc 31 along the flexible shaft 4, so that the rotating disc 31 rotates. The rotation of the rotating disc 31 drives the mowing blade 32 to work and cut the grass and vegetation. At the same time, when the rotating disc 31 rotates, the transmission rod 36 on the outer wall will also rotate with the rotating disc 31, so that the transmission rod 36 acts on the slider 34, and transmits the force to the slider 34 to enable it to move in the arc groove 33. The movement of the slider 34 drives the push rod 35 under the slider 34 to move, so that the push rod 35 can be moved to clean hard objects on the ground to prevent the mowing blade 32 from hitting hard objects and causing damage to the machine.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
