[0048] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 2 , the plurality of trimming blades 21 of the bearing plate 2 are divided into a plurality of columns, and the trimming blades 21 of adjacent two columns are arranged at intervals, in order to simplify the arrangement structure of the trimming blades 21, in combination with the accompanying drawings Figure 2As shown, only three trimmer blades 21 are displayed. The first column has two trimmer blades 21, and the line connecting the centers of the two trimmer blades 21 in the first column is perpendicular to the forward direction of the machine body 1. The second column has one trimmer blade 21, and the center of the second trimmer blade 21 lies on the perpendicular bisector of the line connecting the centers of the two nearest trimmer blades 21 in the first column. The minimum distance between the two trimmer blades 21 in the first column on their rotational trajectories is less than or equal to the diameter of the rotational trajectory of the trimmer blade 21 in the second column.

[0049] If there are untrimmed grass blades in the area traversed by the first row of trimming leaves 21, they can be trimmed by the subsequent rows of trimming leaves 21.

[0050] See attached document Figure 1 Appendix Figure 3 and appendix Figure 4 As shown, a rotating groove 11 for rotating a support plate 2 is provided inside the body 1. The portion of the support plate 2 with the trimming blades 21 is outside the body 1, while the portion without the trimming blades 21 is inside the body 1, i.e., inside the rotating groove 11.

[0051] See attached document Figure 1 Appendix Figure 3 and appendix Figure 4 As shown, a drive assembly 4 is provided inside the machine body 1. The drive assembly 4 is used to drive the drive block 3 to move in the vertical direction. The drive assembly 4 includes a lead screw 41, which is rotatably disposed inside the machine body 1 and is vertically disposed. The drive block 3 is threadedly connected to the lead screw 41. A drive source 5 is provided inside the machine body 1. The drive source 5 is used to drive the lead screw 41 to rotate. The drive source 5 is a motor 51, which is installed inside the machine body 1 and has its output shaft facing upward. The lead screw 41 is coaxially fixedly connected to the output shaft of the motor 51.

[0052] Before the operator trims the grass leaves on the lawn, first, the overall orientation of the grass leaves is observed, the body 1 is placed on the side where the grass leaves are oriented, then the operator starts the motor 51, the output shaft of the motor 51 drives the lead screw 41 to rotate, the lead screw 41 drives the driving block 3 to move downward, the driving block 3 drives the bearing plate 2 to rotate along the rotating shaft 22 through the driving shaft 31, so that the side exposed by the bearing plate 2 and the trimming blade 21 inside the bearing plate 2 rotate upward, so that the plane where the trimming blade 21 rotates can be opposite to the grass leaves (here, "opposite" is an ideal state, for ease of description), finally, the operator controls the driving wheel 141 and the trimming blade 21 to rotate, so that the body 1 drives on the lawn while trimming the grass leaves.

[0053] Referring to Figs. 1-3, Figure 1 , Figs. 4-6, Figure 3 and Figs. 7-9, Figure 4 it is shown that a closed groove 12 is formed in the body 1 in the vertical direction, the closed groove 12 is communicated with the rotating groove 11, a closing plate 6 is slidably installed in the closed groove 12 in the vertical direction, a through groove 61 is formed in the closing plate 6 in the horizontal direction, the through groove 61 is communicated with the rotating shaft 22, and the bottom wall of the side of the through groove 61 away from the rotating shaft 22 is in a circular arc shape or an inclined straight line shape (only the inclined state is shown in the figure) Figure 4 , so that the scattered grass leaves can slide downward. A lead screw 62 is rotatably installed in the body 1, the lead screw 62 is vertically arranged, the closing plate 6 is threadedly connected to the lead screw 62, the top end of the lead screw 62 is coaxially fixedly connected with a synchronous wheel 621, the top end of the lead screw 41 is coaxially fixedly connected with a synchronous wheel 411, and the synchronous wheel 411 and the synchronous wheel 621 are jointly sleeved with a synchronous belt 412.

[0054] Under the blocking effect of the closing plate 6, the scattered grass leaves entering the body 1 along the rotating groove 11 are reduced, and the influence of the scattered grass leaves on the normal operation of the body 1 is also reduced. After the operator starts the motor 51, on the one hand, the motor 51 can drive the bearing plate 2 to rotate through the lead screw, the driving block 3 and the driving shaft 31, so as to adjust the inclination angle of the trimming blade 21. On the other hand, the motor 51 drives the lead screw 62 to rotate through the lead screw 41, the synchronous wheel 411, the synchronous belt 412 and the synchronous wheel 621, so that the lead screw 62 drives the closing plate 6 to move in the vertical direction, so that the position of the through groove 61 follows the movement of the bearing plate 2, so as to reduce the interference of the closing plate 6 on the rotation of the bearing plate 2.

[0055] Referring to Figs. 10-12, Figure 3 and Figs. 13-15, Figure 4As shown, the top surface of the bearing plate 2 and the bottom surface of the bearing plate 2 are fixedly connected with arc-shaped plates 25, the center of the inner arc of the arc-shaped plate 25 is on the axis of the rotating shaft 22, and the two arc-shaped plates 25 are symmetrical about the bearing plate 2.

Due to the matching of the arc-shaped plates 25 and the inner walls of the arc-shaped grooves 63, the arc-shaped plates 25 hinder the entry of the splashed grass leaves into the inside of the machine body 1.

[0056] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 5 As shown, the front side of the machine body 1 is provided with a radar 101, that is, the radar 101 is located on the side of the machine body 1 close to the bearing plate 2, two motor threes 14 are arranged in the machine body 1, the motor threes 14 can adjust the rotating speed according to the electromagnetic waves fed back after the radar 101, and the two motor threes 14 and the two drive wheels 141 are one-to-one corresponding, and the drive wheels 141 are coaxially and fixedly connected to the output shafts of the corresponding motor threes 14.

[0057] The radar 101 emits electromagnetic waves in the forward direction of the machine body 1, which is used to detect whether the grass leaves in the forward direction of the machine body 1 are trimmed or not, that is, the reflected electromagnetic waves are received by the components in the machine body 1 and are analyzed and processed. If it is determined that the trimming is completed, the two motor threes 14 adjust the rotating speed respectively, so that the rotating speed of one of the motor threes 14 is faster than that of the other motor three 14, the steering and turning of the machine body 1 are completed, and the automatic operation of the machine body 1 is realized, without manual control by the operator, and the intelligent lawn trimming of the machine body 1 is realized (whether steering or turning can be obtained by the algorithm written in advance, and the electromagnetic waves fed back are analyzed).

[0058] If it is determined that the trimming is not completed, the two motor threes 14 continuously maintain the same rotating speed, so that the machine body 1 maintains straight-line driving and continuously trims the grass leaves.

[0060] Then, the motor one 51 is started, the motor one 51 indirectly drives the bearing plate 2 and the trimming blades 21 in the bearing plate 2 to rotate upward, so that the plane where the rotating track of the trimming blades 21 is located can be perpendicular to the grass leaves;

[0061] Finally, the motor two 26 and the motor three 14 are started, so that the trimming blades 21 and the step track 13 start to rotate, at this time, the machine body 1 can move forward while trimming the grass leaves.

[0062] In summary, the device can adjust the inclination angle of the trimming blade 21 according to the orientation of the grass leaves, so that the plane where the rotation track of the trimming blade 21 is located can be perpendicular to the grass leaves, and the trimming of the grass leaves is completed.
