Description

Technical Field

[0001] This utility model relates to the field of laser weeding equipment technology, and in particular to a laser striking head position adjustment mechanism and a laser weeding device. Background Technology

[0002] In agricultural production and industrial site cleanup, weed growth can affect crop yields and equipment operation, making weeding a crucial step. With the development of laser technology, laser weeding equipment has gradually replaced traditional manual and chemical weeding methods, becoming the mainstream type of weeding equipment due to its advantages such as no chemical pollution, high efficiency, and strong targeting of specific weeds.

[0003] The core component of laser weeding equipment is the laser striking assembly, and its position adjustment accuracy directly determines the weeding effect. If the laser striking assembly cannot be precisely positioned to match the weed distribution area, it is easy to miss weeds or accidentally hit crops. However, most laser weeding equipment on the market currently uses a fixed installation design for its laser striking assembly, meaning the laser striking assembly is rigidly connected directly to the equipment frame. This makes it impossible to flexibly adjust its position according to the distribution and type of weeds. The striking range can only be adjusted by moving the entire weeding equipment, which greatly limits its operation. Especially in scenarios where weeds are scattered or crop row spacing is irregular, it is difficult to achieve precise weeding. Furthermore, due to the different heights of weeds, a fixed installation may not be able to remove shorter weeds, resulting in low weeding efficiency.

[0004] Therefore, it is necessary to design a laser striking head position adjustment mechanism and a laser weeding device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laser striking head position adjustment mechanism and a laser weeding device. This invention can adjust the height and position of the laser striking component, thereby improving the weed removal effect. Furthermore, through the setting of the positioning component, the threaded hole of the laser striking component can be quickly aligned with the threaded hole of the placement frame, facilitating the positioning and installation of the laser striking component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser strike head position adjustment mechanism includes a truss with a horizontally arranged slide groove, the slide groove being trapezoidal, and a trapezoidal block slidably connected within the slide groove; a movable frame with two vertically arranged strip openings, a locking mechanism passing through each strip opening connecting the movable frame and the trapezoidal block; a placement frame fixedly connected to the lower end of the movable frame, a laser strike assembly placed within the placement frame, and the laser strike assembly connected to the placement frame by multiple fixing bolts.

[0008] Preferably, the locking mechanism includes a locking bolt that is threaded through the trapezoidal block, the movable end of the locking bolt passing through the strip opening and the head being tightly fitted against the outer wall of the movable frame.

[0009] Preferably, each of the placement racks is provided with a positioning component, the positioning component including a fixing block fixedly connected to the left and right sides of the placement rack, two front baffles fixedly connected to the front side of the placement rack, a threaded rod rotatably connected through the fixing block on the right side, movable blocks provided on the left and right sides of the placement rack, the movable block on the right side being threadedly connected to the threaded rod, connecting rods fixedly connected to the rear sides of the two movable blocks, a rear push plate fixedly connected to the rear sides of the two connecting rods, and a knob fixedly connected to the front side of the threaded rod.

[0010] Preferably, a guide rod is fixedly connected through the fixed block on the left side, and the movable block on the left side is slidably connected to the guide rod.

[0011] Preferably, the inner wall of each groove is sandblasted to form a rough surface, and the surface roughness Ra value of the rough surface is 3.2-6.3 μm.

[0012] Preferably, each of the fixing bolts is fitted with an elastic washer on its outer side, the elastic washer being made of nitrile rubber, and the inner sidewall of the placement rack is provided with a buffer pad.

[0013] A laser weeding device includes: a vehicle body and a laser head position adjustment mechanism as described in any one of the above-mentioned methods, wherein the laser head position adjustment mechanism is fixedly mounted on the upper end of the vehicle body by a plurality of screws.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with existing technologies, by using the sliding groove of the truss strip steel and the strip opening of the mobile frame and the locking bolts, the laser striking component can be flexibly slidably adjusted along the sliding groove or vertical direction. Moreover, the horizontal and vertical position adjustments can be completed without disassembly and reassembly, which can effectively adapt to the operation scenario where weeds are scattered and crop row spacing is irregular, and greatly improve the accuracy of weeding and the efficiency of operation.

[0016] 2. Compared with the existing technology, this device greatly improves the installation convenience of the laser strike component through the positioning component: the positioning component on the placement frame drives the right moving block to slide through the rotation of the threaded rod, and with the left moving block sliding synchronously along the guide rod, it can push the rear push plate forward, which works with the front baffle to limit the laser strike component, quickly calibrate the position of the threaded hole of the laser strike component and the threaded hole of the placement frame, without the need for repeated alignment and adjustment, significantly shortening the installation time and improving the assembly efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A laser strike head position adjustment mechanism includes a truss 6, a horizontally provided slide groove 7 on the truss 6, the slide groove 7 is trapezoidal, and a trapezoidal block 15 is slidably connected in the slide groove 7.

[0025] The mobile frame 9 is made of aluminum alloy, which is lightweight and strong. The mobile frame 9 has two vertical strip openings 10. The mobile frame 9 and the trapezoidal block 15 are connected by a locking mechanism that passes through each strip opening 10. The lower end of the mobile frame 9 is fixedly connected to a placement frame 11. The placement frame 11 contains a laser attack component 12. The laser attack component 12 includes a laser emitter, a focusing lens and a protective shell. The protective shell is made of stainless steel and has a rust-proof coating. The power of the laser emitter can be adjusted according to the type of weed. The focusing lens can focus the laser beam into a spot with a diameter of 1-3mm to improve weeding efficiency. The laser attack component 12 is connected to the mobile frame 9 by multiple fixing bolts 13.

[0026] The locking mechanism includes a locking bolt 8 that is threaded through the trapezoidal block 15. The movable end of the locking bolt 8 passes through the strip opening 10 and its head is in close contact with the outer wall of the movable frame 9. The screw of the locking bolt 8 is provided with an anti-slip washer on the contact surface between the screw and the wall of the slide groove 7, which further enhances the friction with the rough inner wall of the slide groove 7.

[0027] Each placement frame 11 is equipped with a positioning component. The positioning component is used to quickly calibrate the installation position of the laser striking component 12, reduce assembly time, and avoid errors caused by manual alignment. The positioning component includes fixed blocks that are fixedly connected to the left and right sides of the placement frame 11. Two front baffles 14 are fixedly connected to the front side of the placement frame 11. A threaded rod 5 is rotatably connected through the fixed block on the right side. There are movable blocks 2 on both the left and right sides of the placement frame 11. The movable block 2 on the right side is threadedly connected to the threaded rod 5. A connecting rod is fixedly connected to the rear side of each of the two movable blocks 2. A rear push plate 3 is fixedly connected to the rear side of the two connecting rods. A knob 4 is fixedly connected to the front side of the threaded rod 5. A guide rod is fixedly connected through the fixed block on the left side. The movable block 2 on the left side is slidably connected to the guide rod.

[0028] The inner wall of each chute 7 is sandblasted to form a rough surface. Quartz sand is used as the abrasive for sandblasting, and the sandblasting pressure is controlled at 0.4-0.6MPa to ensure uniform surface roughness. The surface roughness Ra value of the rough surface is 3.2-6.3μm. Each fixing bolt 13 is fitted with an elastic washer on the outside. The elastic washer is made of nitrile rubber to prevent the fixing bolt 13 from loosening due to vibration. The inner wall of the placement frame 11 is provided with a buffer pad to protect the laser impact component 12 and prevent damage caused by collision with the placement frame 11 during installation or operation.

[0029] A laser weeding device includes a vehicle body 1 and the aforementioned laser head position adjustment mechanism, which is fixedly mounted on the upper end of the vehicle body 1 by a plurality of screws.

[0030] The functional principle of this utility model can be explained through the following operation: When adjusting the position of the laser strike component 12, the adjustment state needs to be unlocked first. When it is necessary to adjust the lateral or longitudinal position of the laser strike component 12, first loosen the locking bolt 8 in the strip opening 10 on the moving frame 9, so that the locking bolt 8 separates from the rough inner wall of the strip steel groove 7 of the truss 6. Since the moving frame 9 is pressed on the trapezoidal block by the locking bolt, when the locking bolt 8 is loosened, the pressure on the moving frame 9 is released, so that the moving frame 9 can move up and down; then, the position is adjusted by sliding, pushing the moving frame 9. The trapezoidal block 15 is slid along the slide 7 or the moving frame 9 is moved down. According to the distribution of weeds or the operation requirements, the laser striking component 12 is adjusted to the target horizontal / vertical position. During the process, the limiting blocks at both ends of the slide 7 can prevent the moving frame 9 from sliding out of the slide 7. Finally, the position is locked and fixed. After the adjustment is in place, the locking bolt 8 is tightened so that the tail of the locking bolt 8 is tightly abutted against the rough inner wall of the slide 7. At the same time, the locking bolt 8 tightly presses the moving frame 9 onto the truss 6. The increased friction of the rough surface is used to fix the moving frame 9 and ensure that the position of the laser striking component 12 does not shift.

[0031] In the positioning and installation operation of the laser strike component 12, the component is first initially placed into the placement frame 11, with the front side of the component adhering to the front baffle 14 of the placement frame 11, thus completing the initial positioning. Next, the positioning component is activated, and the threaded rod 5 on the right fixed block of the placement frame 11 is rotated. The threaded rod 5 drives the right moving block 2 to slide along its axis, while the left moving block 2 slides synchronously along the guide rod. The two moving blocks 2 drive the rear push plate 3 to move forward through the connecting rod. Then, the threaded holes are precisely aligned. At this time, the threaded holes of the laser strike component 12 and the threaded holes of the placement frame 11 are automatically aligned without repeated calibration. Finally, the fixed installation is completed. The laser strike component 12 is fixed to the placement frame 11 and the moving frame 9 by passing the fixed bolts 13 through the aligned threaded holes. The buffer pad can reduce the collision damage between the component and the placement frame 11, and the anti-slip texture on the surface of the buffer pad further prevents the component from shifting.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
