Description

Technical Field

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

[0002] In scenarios such as agricultural laser weeding and industrial equipment transportation, the transport mechanism, as a core load-bearing component, directly impacts the continuity of the overall operation due to its ease of assembly / disassembly and maintenance efficiency. If the transport mechanism malfunctions, rapid repair is crucial to minimize downtime losses. However, current mainstream transport mechanisms generally adopt an "integrated frame" design. While this design meets basic load-bearing requirements, it suffers from significant technical deficiencies in assembly / disassembly and maintenance, becoming a key bottleneck restricting the improvement of operational efficiency.

[0003] First, the integrated frame offers extremely poor flexibility in disassembly and assembly. Traditional transport mechanisms are often assembled by integral welding or with numerous fixed connectors (such as non-removable rivets and multiple sets of staggered bolts). If one side of the frame malfunctions (e.g., stuck wheels, frame deformation, axle wear), maintenance requires moving the entire transport mechanism from the work site to a dedicated maintenance area before disassembling the faulty section. This process is cumbersome, consuming significant manpower and time, and may also damage the connection precision of other non-faulty components due to frequent disassembly, increasing the risk of secondary malfunctions.

[0004] Therefore, it is necessary to design a transport mechanism and laser weeding equipment to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a transport mechanism and laser weeding equipment. This utility model is lighter overall and can be disassembled and transferred to a dedicated maintenance area for repair when one side of the frame malfunctions. At the same time, the mechanism uses positioning components and side baffles to align the connecting holes on the fixed seat and the longitudinal beam, making it easy to lock them in place using fixing bolts and nuts.

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

[0007] A transport mechanism includes two frames, two crossbeams, multiple mounting seats, casters, and two longitudinal beams. The two ends of the two crossbeams are connected to the two frames by multiple locking bolts. The multiple mounting seats are rotatably connected to the lower ends of the two frames. The multiple casters are rotatably mounted in the mounting seats via axles. Two fixed seats are installed at the upper ends of the two crossbeams. The two longitudinal beams are erected in the corresponding two fixed seats. Each fixed seat is provided with a fixing bolt, each fixing bolt passes through the longitudinal beam, and each fixing bolt is threaded with a nut.

[0008] Preferably, each of the crossbeams is provided with a positioning component, the positioning component including a positioning block fixedly connected to the crossbeam, each positioning block having a Y-shaped through groove, the inner top of the Y-shaped through groove being fixedly connected with a positioning pin, and each longitudinal beam having a positioning hole that mates with the positioning pin.

[0009] Preferably, each of the positioning blocks is fixedly connected to a side baffle on the side away from the crossbeam. The side baffle is integrally formed by an L-shaped plate and an inclined plate, with the inclined plate located above the L-shaped plate.

[0010] A laser weeding device includes a truss, an electrical box, and a transport mechanism as described in any one of the above, wherein a laser component is mounted on the truss.

[0011] Preferably, the electrical box is equipped with a water-cooling device, an optomechanical laser, and a power supply. The optomechanical laser is connected to multiple laser components via wires, and the power supply is electrically connected to the optomechanical laser and the water-cooling device via wires.

[0012] Preferably, the electrical box has multiple heat dissipation holes on the rear side; the top of the electrical box has a dust cover, which is rotatably connected to the box body via a hinge, and the lower surface of the dust cover has a sealing strip.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with the prior art, this utility model splits the transport mechanism into two independent frames, which are detachably connected to the crossbeam by multiple locking bolts. When a single frame fails, there is no need to remove other supporting components. Only the locking bolts between the corresponding frame and the crossbeam need to be loosened to remove the faulty frame separately and then transport it to the maintenance area for maintenance. There is no need to transport the entire equipment, which not only reduces the consumption of manpower, but also makes maintenance more convenient.

[0015] 2. Compared with existing technologies, this device significantly improves the assembly efficiency and hole alignment accuracy of the electrical box and crossbeam through the coordinated design of the positioning components and side baffles. The Y-shaped through slot on the positioning block can guide the longitudinal beam to be quickly placed into the preset position of the fixed seat. With the precise cooperation of the positioning pin and the positioning hole of the longitudinal beam, the connection hole between the longitudinal beam and the fixed seat can be automatically aligned without repeated manual calibration, avoiding the tedious manual adjustment operation in existing technologies. At the same time, the side baffle can effectively limit the lateral sliding and outward tilt of the longitudinal beam, preventing hole misalignment caused by longitudinal beam displacement during assembly.

[0016] 3. Compared with existing technologies, this device significantly improves the convenience of subsequent maintenance and the continuity of equipment operation. When it is necessary to inspect the internal components of the electrical box, after removing the fixing bolts, the longitudinal beam can be quickly removed along the Y-shaped through groove of the positioning block. When reinstalling, there is no need to readjust the hole position, which greatly shortens the equipment downtime for maintenance. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-2A transport mechanism includes two frames 1, two crossbeams 8, multiple mounting seats 2, casters 3, and two longitudinal beams 10. The two ends of the two crossbeams 8 are connected to the two frames 1 by multiple locking bolts. The locking bolts are made of high-strength stainless steel, and their number is set according to the connection length between the frame 1 and the crossbeams 8, with no less than two bolts at each end. A flat washer is fitted on the outer side of the bolt thread, located between the mating surfaces of the frame 1 and the crossbeams 8, enhancing the sealing and anti-slip properties of the connection. The multiple mounting seats 2 are rotatably connected to the lower ends of the two frames 1. The rotatable connection between the mounting seats 2 and the frame 1 is achieved through bearings. The bearings are embedded in pre-set mounting holes at the lower end of the frame 1. A connecting shaft extends from the upper end of the mounting seat 2, adapting to the inner ring of the bearing. The connecting shaft and the inner ring of the bearing are interference-fitted, ensuring that the mounting seat 2 can rotate flexibly and the connection is stable. The multiple casters 3 are rotatably mounted on the frame 1 via axles. Inside the mounting base 2, two fixing seats 9 are installed at the upper ends of the two crossbeams 8. The fixing seats 9 are fixed to the crossbeams 8 by welding. Before welding, the contact surfaces of the two are derusted to ensure the welding strength. The two fixing seats 9 on the same crossbeam 8 are symmetrically distributed along the length of the crossbeam 8. The inner side wall of the fixing seat 9 is provided with a groove that matches the longitudinal beam 10. The depth of the groove matches the height of the longitudinal beam 10, which can play a preliminary positioning role for the longitudinal beam 10. The two longitudinal beams 10 are set in the corresponding two fixing seats 9. Each fixing seat 9 is provided with a fixing bolt 12. Each fixing bolt 12 passes through the longitudinal beam 10. Each fixing bolt 12 is threaded with a nut 11. The fixing bolt 12 and the nut 11 are galvanized. A spring washer is provided between the nut 11 and the longitudinal beam 10. The spring washer is in a compressed state, which can effectively prevent the nut 11 from loosening due to vibration during equipment operation.

[0022] Each crossbeam 8 is equipped with a positioning component, which includes a positioning block 13 fixedly connected to the crossbeam 8. Each positioning block 13 is equipped with a Y-shaped through groove, and a positioning pin 14 is fixedly connected to the inner top of the Y-shaped through groove. Each longitudinal beam 10 is equipped with a positioning hole that mates with the positioning pin 14. The diameter of the positioning hole matches the diameter of the positioning pin 14. The position of the positioning hole corresponds exactly to the position of the positioning pin 14 when the longitudinal beam 10 is installed in the fixed seat 9. Each positioning block 13 is fixedly connected to a side baffle 6 on the side away from the crossbeam 8. The side baffle 6 is integrally formed by an L-shaped plate and an inclined plate, with the inclined plate located above the L-shaped plate.

[0023] A laser weeding device includes a truss 4, an electrical box 7, and the aforementioned transport mechanism. A laser component 5 is mounted on the truss 4, and the electrical box 7 is welded between two longitudinal beams 10.

[0024] The electrical box 7 houses a water-cooling system, an optomechanical laser, and a power supply. An internal partition divides the interior of the electrical box 7 into three independent chambers, each for a separate compartment. Ventilation holes on the partition facilitate airflow between the chambers. The optomechanical laser is connected to multiple laser components 5 via wires, and the power supply is electrically connected to the optomechanical laser and water-cooling system via wires. Multiple heat dissipation holes are located on the rear side of the electrical box 7. A dust cover is mounted on the top of the electrical box 7. Two stainless steel hinges are symmetrically installed on one side of the dust cover, allowing for flexible rotation up to 180° for easy access and maintenance. A sealing strip is located on the lower surface of the dust cover.

[0025] The functional principle of this utility model can be explained through the following operation: In the assembly and positioning stage, the primary task is to achieve precise and efficient assembly of the electrical box 7 and the carrying mechanism: When assembling the electrical box 7, the longitudinal beams 10 welded on its left and right sides are first placed along the Y-shaped through slots of the positioning blocks 13 on the cross beam 8. The inclined guide structure of the Y-shaped through slot can guide the longitudinal beams 10 to automatically slide to the preset position of the fixed seat 9 without repeated manual adjustment. When the longitudinal beams 10 slide to the target position, the positioning pins 14 at the top of the Y-shaped through slots of the positioning blocks 13 will accurately embed into the positioning holes on the longitudinal beams 10, completing the initial positioning of the longitudinal beams 10 and the fixed seat 9, ensuring that the connection holes on both are completely aligned; During the process, the side baffle 6 (integratedly formed by L-shaped plate and inclined plate) on the side of the positioning block 13 away from the crossbeam 8 will form a double limit from the outside of the longitudinal beam 10. The inclined plate assists the longitudinal beam 10 to slide smoothly into the limiting area of ​​the L-shaped plate, while the L-shaped plate restricts the lateral sliding and outward tilting of the longitudinal beam 10, preventing the longitudinal beam 10 from shifting during the subsequent locking operation, and further ensuring the alignment accuracy of the connecting holes. After the positioning is completed, the fixing bolt 12 is passed through the alignment hole of the fixing seat 9 and the longitudinal beam 10, and then the nut 11 is put on and tightened. Since the hole has been accurately aligned by the positioning component, the fixing bolt 12 can be smoothly inserted and the force is even, avoiding the bolt deformation or hole damage caused by forced insertion in the prior art.

[0026] During operation, the movable wheels 3 inside the mounting base 2 at the lower end of the frame 1 rotate through the axles, driving the entire transport mechanism to move in the field. The design of the mounting base 2 being rotatably connected to the frame 1 allows the movable wheels 3 to flexibly adjust their angle according to the uneven road conditions in the field, ensuring the smooth travel of the transport mechanism and preventing the components inside the electrical box 7 from shaking or the laser component 5 from shifting due to bumps. The electrical box 7, as the control core, houses the power supply for the optomechanical laser and the water-cooling equipment. The optomechanical laser is connected to the laser component 5 on the truss 4 via wires, providing energy for laser weeding. At the same time, the heat dissipation holes on the rear side of the electrical box 7 can help dissipate the heat generated by the optomechanical laser during operation. Combined with the water-cooling equipment, this achieves dual heat dissipation, preventing component failure due to high temperature. The dust cover and sealing strip can isolate dust and moisture in the field, preventing them from entering the box and damaging the internal electrical components, ensuring continuous operation of the equipment. The truss 4 is installed on the upper end of the transport mechanism, precisely aligning the laser component 5 with the weed area, and working in conjunction with the movement of the transport mechanism to achieve continuous and efficient weeding operations.

[0027] 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.
