Description

Technical Field

[0001] This invention relates to the field of laser weeding machine technology, specifically an intelligent laser weeding machine. Background Technology

[0002] Manual weeding involves removing weeds using hand tools or manual labor. This method is suitable for small areas or places where machinery is difficult to use. Its advantage is that it can eradicate small weeds, but its disadvantages are low efficiency and high cost. Chemical weeding uses chemical agents to kill weeds. This method can quickly and effectively control weed growth, but it can have adverse effects on the environment and crops. To address this issue, an intelligent laser weeding robot has been developed. This innovative device uses AI to accurately identify weeds and precisely remove them using laser technology. Equipped with a laser head, lighting, and a high-resolution camera, it supports both automatic and manual modes. In automatic mode, no manual intervention is required. In manual mode, the robot's path can be actively controlled via a remote control panel, weed removal operations can be planned, and the machine's status can be monitored in real time. Through high-speed photography and artificial intelligence technology, it accurately identifies weeds and crops, and uses laser light to irradiate the weeds, causing the surface moisture of the weed blades to evaporate rapidly. The liquid inside the weed cells vaporizes and expands, causing the weed tissue to rupture, thus achieving the weeding effect.

[0003] However, when using a small intelligent laser weed cutter, the laser weed cutter moves in the field by means of rollers. Due to the unevenness of the field, the laser weed cutter is prone to a lot of shaking during the movement, which will affect the laser head's accurate targeting of the weeds.

The movable base 1 slides on the top of a slide rail 4, which is composed of a first crossbar 5 and a second crossbar 6. The first crossbar 5 and the second crossbar 6 are assembled by an assembly mechanism 7. The movable base 1 is slidably connected to the outer wall of the slide rail 4 by a displacement mechanism 8. The assembly mechanism 7 includes a connecting rod 701, and mounting seats 702 are fixedly connected to both ends of the connecting rod 701. A positioning rod 703 is fixedly connected to the bottom end of mounting base 702. A fixed shaft 706 is rotatably connected to the top end of mounting base 702. A second rotating block 705 is fixedly connected to the outer wall of fixed shaft 706. A second crossbar 6 is rotatably connected to one end of second rotating block 705. A first rotating block 704 is rotatably connected to the outer wall of fixed shaft 706. A first crossbar 5 is rotatably connected to one end of first rotating block 704. A rotating hole 707 for fixed shaft 706 to rotate is opened on the outer wall of first rotating block 704. The first crossbar 5 and the second crossbar 6 face the first rotating block 704 and the second rotating block 705. Each of the rotating blocks 705 has an arc-shaped surface 10 and a flat surface 11 at one end. The outer wall of the second rotating block 705 has a slot 708. An insert block 709 is slidably connected inside the first rotating block 704. A threaded rod 710 extending into the insert block 709 is rotatably connected inside the first rotating block 704. One end of the threaded rod 710 is fixedly connected to a rotating column 711. The assembly mechanism 7 also includes a slot 712, which is located on the outer wall of the mounting base 702 and below the second rotating block 705. An extension rod 710 is slidably connected inside the second rotating block 705. A locking block 713 extends out of the second rotating block 705 and extends to the inner wall of the slot 708. A first spring 714 is connected between the locking block 713 and the second rotating block 705. A connecting groove 715 is provided at one end of the first crossbar 5. A fixing groove 716 is provided on the inner wall of the connecting groove 715. A connecting seat 717 extending to one end of the second crossbar 6 is slidably connected inside the second crossbar 6. A fixing frame 718 extending out of the connecting seat 717 is slidably connected inside the connecting seat 717.

[0021] In this embodiment: when assembling the slide rail 4 (e.g. Figure 3(As shown), at this time, rotate the first rotating block 704 and the second rotating block 705 to separate the first horizontal bar 5 and the second horizontal bar 6. Rotate the first horizontal bar 5 and the second horizontal bar 6 respectively so that the second horizontal bar 6 and the second rotating block 705, as well as the first horizontal bar 5 and the first rotating block 704, form a 90-degree angle. Then rotate the second rotating block 705 and the first rotating block 704 to a vertical state. At this time, the locking block 713 is engaged into the locking groove 712 by the elastic force of the first spring 714. The planes 11 on the first horizontal bar 5 and the second horizontal bar 6 are in contact, thereby making the first horizontal bar 5 and the second horizontal bar 6 fit together. The second crossbar 6 cannot be rotated. Then, the rotating column 711 is rotated, causing the threaded rod 710 to rotate. The threaded rod 710 rotates, causing the insert block 709 to shift. The insert block 709 shifts and inserts into the slot 708, fixing the second rotating block 705 and the first rotating block 704. Simultaneously, the shifted insert block 709 contacts the locking block 713, eliminating any space for the locking block 713 to shift, thus fixing the second rotating block 705 and the first rotating block 704. This, in turn, fixes the first crossbar 5 and the second crossbar 6 (e.g., ...). Figure 4 (as shown) After completion, the positioning rod 703 is inserted into the ground, and the connecting rod 701 is installed. Multiple connecting rods 701 are installed in sequence. When one end of the first crossbar 5 and the second crossbar 6 are in contact, the connecting seat 717 is pushed and inserted into the connecting groove 715. The fixing bracket 718 is engaged into the fixing groove 716 by the elastic force of the second spring 719, thus fixing the first crossbar 5 and the second crossbar 6, thereby improving the stability of the slide rail 4, and thus completing the assembly of the slide rail 4.

One end of the displacement seat 802 is rotatably connected to a first spur gear 803, and the other end is rotatably connected to a second spur gear 805. The first spur gear 803 and the second spur gear 805 are fixedly connected by a connecting shaft 804. A reinforcing groove 806 is formed at the top of the displacement seat 802, and a movable groove 807 is formed at the top of the movable seat 1. A movable plate 808 is slidably connected to the inner wall of the movable groove 807, and a reinforcing rod 809 is fixedly connected to the bottom end of the movable plate 808. The displacement mechanism 8 also includes a motor 810, which is mounted on... At the top of the movable plate 808, the output end of the motor 810 is connected to a first bevel gear 811. Inside the movable plate 808, a second bevel gear 812 is rotatably connected to the outer wall of the first bevel gear 811. The inner wall of the second bevel gear 812 is fixedly connected to a mounting shaft 813. Both ends of the mounting shaft 813 are fixedly connected to a third spur gear 814.

At this time, the first spur gear 803 is located on one side of the slide groove 801, pushing the displacement seat 802 to move. The displacement of the displacement seat 802 drives the first spur gear 803 to move into the slide groove 801. The first spur gear 803 contacts the slide groove 801. At this time, the reinforcing groove 806 moves to the bottom end of the reinforcing rod 809, pushing the movable plate 808 downward in the movable groove 807. The displacement of the movable plate 808 drives the reinforcing rod 809 to move. The reinforcing rod 809 is inserted into the reinforcing groove 806, fixing the displacement seat 802. At the same time, the third spur gear 814 contacts the second spur gear 805. After completion, the reinforcing seat 816 is pushed to move.

At this time, C The frame 818 is engaged into the mounting groove 817 by the elastic force of the third spring 819, fixing the reinforcing seat 816. After completion, the motor 810 is started. The motor 810 drives the first bevel gear 811 to rotate, which in turn drives the second bevel gear 812 to rotate. The second bevel gear 812 drives the mounting shaft 813 to rotate, which in turn drives the third spur gear 814 to rotate. The third spur gear 814 drives the second spur gear 805 to rotate, which in turn drives the connecting shaft 804 to rotate. The connecting shaft 804 drives the first spur gear 803 to rotate, which then slides along the slide groove 801. The displacement of the first spur gear 803 causes the movable seat 1 to move, and the movable seat 1 slides at the top of the slide rail 4, facilitating the smooth movement of the laser weeder in the field.
