[0036] The machine body 10 is also provided with a receiving cavity 104 opened towards the ground, and the cutting assembly 3 is received in the receiving cavity 104. That is, the cutting assembly 3 is located below the machine body 10.
[0037] In the embodiment, the height adjusting assembly 7 is used to adjust the height of the cutting assembly 3 relative to the ground to meet the height required by the user for cutting. In other words, when the height of the machine body 10 relative to the ground is adjusted, the height of the cutting assembly 3 relative to the ground is also adjusted, and at this time the height of the front wheel frame 11 does not change.
[0038] The height adjusting assembly 7 is provided with two height adjusting assemblies and is connected by a connecting rod 701. The two height adjusting assemblies 7 and the connecting rod 701 remain relatively stationary. That is, when one height adjusting assembly 7 moves, the other height adjusting assembly 7 will move synchronously under the driving of the connecting rod 701.
[0039] Specifically, please refer to Figure 2As shown, the height adjustment assembly 7 comprises a height adjustment operating frame 71, a height adjustment support 72, and a height adjustment connecting rod 73 connecting the height adjustment operating frame 71 and the height adjustment support 72, and the height adjustment support 72 is connected to the body 10 and the front wheel frame 11.
[0040] The height adjustment operating frame 71 is arranged between the second walking wheel 22 and the body 10. The height adjustment operating frame 71 is provided with a pair of and is respectively located on the left and right sides of the body 10, and two height adjustment operating frames 71 are connected by a connecting rod 701. Two second walking wheels 22 are respectively pivoted to the corresponding height adjustment operating frame 71, and the height adjustment operating frame 71 is connected to the body 10 through a connecting shaft 711, so that when one side of the height adjustment operating frame 71 rotates, the other side of the height adjustment operating frame 71 can be driven to rotate synchronously through the connecting rod 701, and then the body 10 is raised or lowered relative to the ground.
[0041] In this embodiment, no connecting rod 701 is arranged between the two first walking wheels 21, because the two first walking wheels 21 are both universal wheels and are independent of each other. In this way, the steering angle can be adjusted arbitrarily. Of course, in other embodiments, a connecting rod 701 can also be arranged between the two first walking wheels 21, which is not limited.
[0042] The axis of the height adjustment operating frame 71 is independently arranged with the connecting shaft 711 and the first connecting rod 701, so that when the height adjustment operating frame 71 rotates around the axis, the first connecting rod 701 and the connecting shaft 711 can be driven to rotate, and then the other side of the height adjustment operating frame 71 is driven to rotate synchronously and the body 10 is displaced.
[0043] That is, when the height adjustment operating frame 71 is rotated, the side of the body 10 connected to the height adjustment operating frame 71 will be raised or lowered, thereby adjusting the height of the body 10 from the ground. Preferably, the axis of the height adjustment operating frame 71 is the position pivoted to the second walking wheel 22.
[0044] The height adjustment operating frame 71 is also provided with an operating handle 712, which extends upward from the height adjustment operating frame 71 in the vertical direction perpendicular to the ground. Preferably, the operating handle 712 extends towards the operator, which is designed to be more convenient to use.
[0045] The height adjustment support 72 is arranged close to the first walking wheel 21 and connected to the body 10. The height adjustment support 72 is located between the first walking wheel 21 and the body 10, and the height adjustment support 72 is also provided with two and is respectively located on the left and right sides of the body 10, and two height adjustment supports 72 are respectively connected to the corresponding height adjustment operating frame 71 through the corresponding height adjustment connecting rod 73.
[0046] Preferably, the height adjustment link 73 can be displaced along the advancing direction of the grass mower 100 under the rotation of the height adjustment operating frame 71. Thus, when the height adjustment operating frame 71 rotates, the corresponding height adjustment support 72 can be rotated by the height adjustment link 73, so as to move together with the machine body 10 relative to the front wheel frame 11, thereby adjusting the height of the machine body 10 relative to the ground. In this way, different scene requirements can be met.
[0047] In the embodiment, the machine body 10 is provided with a fixed frame 102 fixedly connected with the height adjustment support 72. The height adjustment support 72 is substantially triangular and connected with the height adjustment link 73 and the front wheel frame 11 respectively. Thus, when the height adjustment operating frame 71 drives the height adjustment link 73 to move, the height adjustment support 72 can be rotated relative to the front wheel frame 11.
[0048] Please refer to Figure 4 the first positioning point 721 connected with the fixed frame 102, the second positioning point 722 connected with the height adjustment link 73, and the third positioning point 723 connected with the front wheel frame 11. During the movement of the height adjustment operating frame 71 driving the height adjustment link 73, the first positioning point 721 and the second positioning point 722 are displaced relative to the third positioning point 723. In other words, the third positioning point 723 serves as the fulcrum of the rotation of the height adjustment support 72, so the position of the third positioning point 723 remains unchanged, and the heights of the first positioning point 721 and the second positioning point 722 are raised or lowered with the driving of the height adjustment link 73.
[0049] The fixed frame 102 and the front wheel frame 11 are connected with a support frame 103. The extension direction of the support frame 103 is parallel to the line between the first positioning point 721 and the third positioning point 723, so as to support the fixed frame 102 and the height adjustment support 72 and maintain the overall balance between the fixed frame 102 and the front wheel frame 11. In other words, the support frame 103, the front wheel frame 11 and the height adjustment support 72 form a balance frame similar to a parallelogram, so as to maintain the balance between the machine body 10 and the front wheel frame 11 during the lifting or lowering process.
[0050] In the embodiment, the line between the first positioning point 721 and the second positioning point 722 has an included angle with the ground. The height of the machine body 10 from the ground is inversely proportional to the included angle.
[0051] Specifically, when the height adjustment handle 71 rotates clockwise, the connecting shaft 711 rotates towards the ground, the height of one side of the machine body 10 decreases, the height adjustment link 73 moves towards the front wheel frame 11, and pushes the height adjustment support 72 to rotate counterclockwise, at this time, the angle between the line connecting the first positioning point 721 and the second positioning point 722 and the ground gradually increases, and the height of the side of the machine body 10 close to the front wheel frame 11 also decreases to be flush with the other side, at this time, the height adjustment of the machine body 10 of the lawn mower 100 is completed to control the mowing height of the cutting assembly 3.
[0052] Similarly, when it is necessary to adjust the height of the machine body 10 from the ground, it is only necessary to rotate the height adjustment handle 71 counterclockwise, at this time, the connecting shaft 711 rotates away from the ground, the height of one side of the machine body 10 increases, the height adjustment link 73 pulls the height adjustment support 72 to rotate clockwise, at this time, the angle between the line connecting the first positioning point 721 and the second positioning point 722 and the ground gradually decreases, and the height of the side of the machine body 10 close to the front wheel frame 11 also increases to be flush with the other side, at this time, the height adjustment of the machine body 10 of the lawn mower 100 is completed to control the mowing height of the cutting assembly 3. Of course, in other embodiments, the relationship between the lifting and lowering of the machine body 10 and the clockwise or counterclockwise rotation of the height adjustment handle 71 is not limited, as long as the rotation direction of the height adjustment handle 71 is opposite to the rotation direction of the height adjustment support 72.
[0053] Please refer to Figure 6 As shown in the figure, the machine body 10 is provided with a plurality of through limiting holes 101 for inserting the pins 731, and the height adjustment link 73 is provided with a limiting groove 730 corresponding thereto, a plurality of limiting holes 101 are located on the movement path of the height adjustment link 73, and the limiting groove 730 can be aligned with the plurality of limiting holes 101 respectively with the movement of the height adjustment link 73, so as to fix the height adjustment link 73 after inserting the pins 731, so that the height adjustment link 73 cannot continue to move, thus, the limiting of the machine body 10 of the lawn mower 100 after completing the height adjustment is realized. Of course, the number and form of the limiting holes 101 can be adjusted according to the actual situation, which is not limited.
[0054] In summary, the lawn mower 100 of the utility model realizes the lifting or lowering of the machine body 1 by setting the height adjustment assembly 7 on the lawn mower 100, to meet the different use requirements of the operator, and expand the application.
[0055] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
