[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] See also Figures 1 to 5The embodiment of the present invention provides an understory weeding equipment for oil tea tree maintenance, including a frame side plate 1, wheels 2 and a ground mowing mechanism 9. A plurality of wheels 2 are installed at the bottom of the frame side plate 1. A cart handrail 3 is also installed on the frame side plate 1 for easy movement. The embodiment of the present invention also includes a stone detection part 7 for detecting whether there are stones and the height of the stones, and a roller cutting mechanism 8 for cutting the grass in the place without stones. The roller cutting mechanism 8 can uproot the grass and has a good weeding effect. The ground mowing mechanism 9 is used to cut the grass in the place with stones, and the grass is cut close to the top of the stones, so as to avoid the stones from causing damage to the roller cutting mechanism 8 and the ground mowing mechanism 9, and to ensure comprehensive weeding as much as possible. The frame side plate 1 is connected with a fixed frame 4, and the fixed frame 4 is equipped with a first linear drive element 5 and a second linear drive element 6. The first linear drive element 5 and the second linear drive element 6 are hydraulic cylinders or electric push rods. The stone detector 7 is installed at the telescopic end of the first linear drive element 5. The first linear drive element 5 enables the stone detector 7 to repeatedly insert into the ground to monitor whether there are stones. The telescopic end of the second linear drive element 6 is equipped with a lifting frame 11, and the roller cutting mechanism 8 is installed at the bottom of the lifting frame 11. A movable plate 12 is arranged above the lifting frame 11. The spacing distance between the top surface of the lifting frame 11 and the movable plate 12 is equal to the height difference between the bottom of the ground mowing mechanism 9 and the bottom of the roller cutting mechanism 8. It is easy to understand that the bottom of the roller cutting mechanism 8 is below the ground, and the bottom of the ground mowing mechanism 9 is above the ground, and the two will form a height difference. When encountering stones, in order to ensure that the roller cutting mechanism 8 and the ground mowing mechanism 9 can both synchronously cross the stones, a spacing distance is specially set. The ground mowing mechanism 9 is installed at the bottom of the movable plate 12, and a support plate 18 is fixedly connected to the frame side plate 1. The support plate 18 is used to support the movable plate 12. The support plate 18 and the movable plate 12 are both arranged horizontally. When the stone detector 7 detects that there are stones on the ground, the height value of the stone will be determined, and then the ground mowing mechanism 9 and the roller throwing mechanism 8 will be raised to the height value through the controller. The controller is electrically connected to the roller throwing mechanism 8 and the ground mowing mechanism 9. The stone detector 7 is located in front of the roller throwing mechanism 8 and the ground mowing mechanism 9. In addition, the stone detector 7 is inserted and pulled out of the ground to loosen the soil, which is convenient for subsequent throwing and cutting operations.

[0028] In the embodiment of the present invention, one of the roller cutting mechanisms 8 corresponds to one ground mowing mechanism 9, one ground mowing mechanism 9 corresponds to a plurality of stone detectors 7, the telescopic end of the first linear drive element 5 is fixedly connected to a lifting plate 10, a plurality of stone detectors 7 are mounted on the lifting plate 10, and a plurality of roller cutting mechanisms 8, ground mowing mechanisms 9 and lifting plates 10 are provided, so that the weeding range is larger and the efficiency is higher.

[0029] In the embodiment of the present invention, the support plate 18 is connected with a guide column 17, the movable plate 12 is provided with a guide hole, the guide column 17 penetrates the guide hole and is connected with the guide hole in a sliding manner, the frame side plate 1 is connected with a fixing seat 14, the fixing seat 14 is connected with the upper surface of the movable plate 12 through a tension spring 13, the side of the movable plate 12 is connected with a guide plate 15, the frame side plate 1 is provided with a guide groove 16, and the guide plate 15 is connected with the inner side surface of the guide groove 16 in a sliding manner. Through the arrangement of the guide column 17, the guide plate 15 and the tension spring 13, the lifting movement of the movable plate 12 is more stable.

[0030] See also Figures 1 to 8 In the embodiment of the present invention, the stone detection member 7 includes a fixed column 71 and a telescopic rod 72. One end of the fixed column 71 is connected to the lifting plate 10. The other end of the fixed column 71 is provided with a blind hole 73.

The pressure sensor 75 is connected to the telescopic rod 72 through a linear spring 74. The telescopic rod 72 is connected to the end surface of the blind hole 73 through a reset spring 76. A wedge-shaped groove is provided at the upper end of the side of the telescopic rod 72, and a mounting groove 77 is provided on the side of the blind hole 73. A wedge block 78 is installed in the mounting groove 77. The wedge block 78 cooperates with the wedge groove. A threaded through hole is provided on the bottom surface of the mounting groove 77. A threaded shaft 102 passes through the threaded through hole. A knob 103 is connected to the outer end of the threaded shaft 102. A telescopic piece 101 is rotatably connected to the inner end of the threaded shaft 102. The telescopic piece 101 is connected to the wedge block 78 by a compression spring 79. The compression spring 79 is always in a compressed state, wherein the top surface of the wedge block 78 is a horizontal surface, and the bottom surface of the wedge block 78 is provided with an inclined surface. When the telescopic rod 72 is inserted into the soil without encountering a stone, the wedge block 78 will not shrink inwards, and the wedge block 78 is stuck in the wedge groove. At this time, the linear spring 74 is at a normal length, and the pressure monitored by the pressure sensor 75 is zero; when the telescopic rod 72 encounters a stone, the wedge block 78 will shrink inwards, the wedge block 78 will be separated from the wedge groove, and the telescopic rod 72 will move upward relative to the fixed column 71. At this time, the linear spring 74 is in a compressed state, and the pressure sensor 75 will monitor the pressure value. The processor can determine the compressed length of the linear spring 74 according to the pressure value and the elastic coefficient of the linear spring 74, and then obtain the height of the stone. When the telescopic rod 72 is not in contact with the stone, the reset spring 76 can reset the telescopic rod 72. In addition, for grounds of different hardness, the compression amount of the compression spring 79 can be adjusted by the knob 103 to ensure that the wedge block 78 does not shrink inwards when the telescopic rod 72 is inserted into the soil.

When the stone detection element 7 detects a stone, the processor will obtain the height of the stone and send the stone height to the controller. The controller will start the second linear drive element 6 according to the height of the stone, so that the roller cutter mechanism 8 rises. When the lifting frame 11 contacts the movable plate 12, it will bring the ground mowing mechanism 9 up until the height of the ground mowing mechanism 9 and the roller cutter mechanism 8 is higher than the stone. At this time, the second motor 91 is started, and the ground mowing mechanism 9 will cut the weeds near the stone. After the set time, the second linear drive element 6 is started again, so that the ground mowing mechanism 9 and the roller cutter mechanism 8 return to their original positions.
