At the same time, the radar detector is set with a height range threshold. When the detected data exceeds the height range, the alarm is triggered to remind the operator whether the trimming height range is exceeded. In this way, the weed trimming can be controlled to operate at the same height to avoid unevenness affecting the aesthetic effect.

[0010] Preferably, the telescopic mechanism also includes a connecting rod fixedly connected to one end of the screw rod, the connecting rod is installed on the inner wall of the shoulder rod through a bearing, and a dial is fixedly sleeved on the surface of the connecting rod, and the dial extends out of the outer surface of the shoulder rod.

[0011] According to the above technical solution, the connecting rod is rotated by rotating the dial, and the rotation of the connecting rod drives the screw rod to rotate.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-Figure 7 A shoulder-back brush cutter that can detect height includes a shoulder-back rod 1 and a hand rod 2 arranged on the surface of the shoulder-back rod 1. One end of the shoulder-back rod 1 is provided with a mounting column 3. The surface of the mounting column 3 is provided with a connecting plate 4 through a bearing. The outer surface of the connecting plate 4 is fixedly sleeved with a blade 5. A height monitoring mechanism is provided on the surface of the shoulder-back rod 1 near the blade 5. The height monitoring mechanism includes a radar detector 6. The radar detector 6 is used to detect its height from the ground. A telescopic mechanism is provided on the surface of the shoulder-back rod 1. The telescopic mechanism includes a screw 7. The length of the shoulder-back rod 1 is adjusted by rotating the screw 7.

[0031] In order to protect the radar detector 6, the height monitoring mechanism also includes a protective shell 61 fixedly mounted on the outer surface of the shoulder pole 1. The radar detector 6 is installed inside the protective shell 61. The protective shell 61 is convenient for blocking grass to prevent the blade 5 from obstructing the use of the radar detector 6 when cutting weeds.

[0032] In order to monitor the height, a control panel 62 and an alarm 63 are installed on the surface of the hand pole 2. The radar detector 6 is used to detect the height of the shoulder pole 1 from the ground. The detected data is displayed on the control panel 62. At the same time, the radar detector 6 is set with a height interval threshold. When the detected data exceeds the height interval, the alarm 63 triggers an alarm to remind the operator whether the trimming height interval is exceeded. In this way, the weed trimming can be controlled to operate at the same height to avoid unevenness affecting the aesthetic effect.

[0033] By setting up a height monitoring mechanism, a radar detector 6 is used to detect the height of the bottom of the shoulder pole 1 from the ground, and the detected data is displayed on the control panel 62. When the detected data exceeds the height range threshold preset by the radar detector 6, the alarm 63 is triggered to remind the operator, thereby controlling the weed trimming to operate at the same height to avoid uneven trimming shapes that affect the appearance.

[0034] In order to make the screw 7 rotate, the telescopic mechanism also includes a connecting rod 71 fixedly connected to one end of the screw 7. The connecting rod 71 is installed on the inner wall of the shoulder rod 1 through a bearing. A dial 72 is fixedly sleeved on the surface of the connecting rod 71. The dial 72 extends from the outer surface of the shoulder rod 1. By rotating the dial 72, the connecting rod 71 is rotated, and the rotation of the connecting rod 71 drives the screw 7 to rotate.

[0035] In order to adjust the length, the surface of the screw 7 is threadedly sleeved with a threaded block 73, and the outer surface of the threaded block 73 is symmetrically installed with a limit bar 74. The surface of the shoulder and back rod 1 is symmetrically distributed with a limit groove 75. The limit groove 75 extends from the opposite side surface of the two limit bars 74 and is fixedly connected with a movable sleeve 76. The inner wall of the movable sleeve 76 is slidably sleeved on the outer surface of the shoulder and back rod 1. The rotation of the screw 7 drives the threaded block 73 connected to it to move along the surface of the screw 7 under the action of the limit bar 74 and the limit groove 75, thereby driving the movable sleeve 76 to move along the surface of the shoulder and back rod 1.

[0036] In order to facilitate angle adjustment, a hinge seat 77 is fixedly installed at one end of the movable sleeve 76. The inner surface of the hinge seat 77 is hinged to the mounting column 3 through a pin shaft, so that the movement of the movable sleeve 76 drives the mounting column 3 to move, thereby adjusting the length of the shoulder rod 1.

[0037] In order to achieve the mowing action, a drive motor 8 is installed inside the mounting column 3. One end of the output shaft of the drive motor 8 is fixedly connected to the connecting disk 4. The rotation of the output shaft of the drive motor 8 drives the connecting disk 4 connected thereto to rotate, and the rotation of the connecting disk 4 drives the blade 5 connected thereto to rotate, thereby achieving the mowing action.

[0038] By providing a telescopic mechanism, the length of the shoulder pole 1 can be easily adjusted to accommodate workers of different heights, thereby improving user comfort.

[0039] Working Principle: Before use, turn the dial 72 as needed. The rotation of the dial 72 drives the connecting rod 71 to rotate, and the rotation of the connecting rod 71 drives the screw 7 to rotate. The rotation of the screw 7 drives the threaded block 73 connected to it to move along the surface of the screw 7 under the action of the limiting strip 74 and the limiting groove 75, thereby driving the movable sleeve 76 to move along the surface of the shoulder rod 1, and then select the appropriate length for shoulder carrying;

[0040] When in use, the radar detector 6 in the protective shell 61 is first activated to detect the height and distance, and the detection data on the control panel 62 is observed. Then, the drive motor 8 in the mounting column 3 is activated. The rotation of the output shaft of the drive motor 8 drives the connecting plate 4 connected thereto to rotate, and the rotation of the connecting plate 4 drives the blade 5 connected thereto to rotate, thereby achieving mowing;

[0041] When the detected data exceeds the altitude interval threshold preset by the radar detector 6, the alarm 63 is triggered to alert the operator.

[0042] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
