Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a laser head for a laser weeding robot. Background Art

[0002] Weeding is an unavoidable process in agricultural planting. Traditional weeding methods typically involve manual and mechanical tillage to promptly control weeds growing in crop fields, but this can damage seedlings and consume significant labor. The latter involves spraying herbicides, which can pollute the soil. Given the shortcomings of these two methods, a new generation of weed control methods is currently using lasers. These methods utilize high-speed photography and artificial intelligence to accurately identify weeds and crops. Lasers are then used to illuminate the weeds, rapidly evaporating moisture from the blades and achieving effective weed control.

[0003] Current laser weeding robots usually use multiple laser transmitters lined up in a row and aimed at the soil below. As the robot moves, it irradiates the weeds directly below, which lacks flexibility. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a laser head for a laser weeding robot, which can be flexibly rotated to improve the flexibility of laser weeding.

[0005] To solve the above technical problems, a laser head for a laser weeding robot is provided, comprising a laser generator, a heat sink mount, and a lens mount. The characteristics of the invention are: a lens mount is provided below the heat sink mount, a heat sink is provided on the heat sink mount, a laser generator is provided below the heat sink, the lens mount is in a circular frame structure, and a convex lens is provided within the circular frame of the lens mount;

[0007] A second L-shaped bracket is provided outside the vertical side of the first L-shaped bracket. One side of the second L-shaped bracket is rotatably connected to the vertical side of the first L-shaped bracket, and the other side of the second L-shaped bracket is bent toward the radiator.

[0008] A first rotating shaft is provided on the outer side of the other side of the second L-shaped bracket, and the first rotating shaft is connected to the first servo motor through a coupling.

[0009] The output end of the first servo motor is provided with a first servo reducer, and the first servo motor is connected to the coupling and the first rotating shaft via the first servo reducer.

[0010] The coupling outer shell is provided with a servo motor mounting seat, and the bottom of the servo motor mounting seat is provided with a mounting seat.

[0011] A buffer is provided below the second rotating shaft.

[0012] A motor fixing seat is provided on the top of the vertical side of the first L-shaped bracket, and a second servo motor and a second servo reducer are provided above the radiator on one side of the motor fixing seat.

[0013] The output end of the second servo motor passes through the second servo reducer and the motor fixing seat in sequence. A synchronous wheel is provided on the second L-shaped bracket below the output end of the second servo motor. A synchronous belt is provided outside the second servo motor and the synchronous wheel. A second rotating shaft is provided inside the front of the synchronous wheel. The synchronous wheel is rotatably connected to the second L-shaped bracket through the second rotating shaft.

[0014] A waist-shaped limiting hole is provided on the second L-shaped bracket, and a limiting rod is provided on the outer side of the vertical side of the first L-shaped bracket, and the limiting rod is embedded in the limiting hole.

The laser head is characterized in that a lens mount 3 is provided below the heat sink mount 2, a heat sink 11 is provided on the heat sink mount 2, and a laser generator 1 is provided below the heat sink 11. The lens mount 3 is a circular frame structure, and a convex lens 15 is provided within the circular frame of the lens mount 3.

[0022] A first L-shaped bracket 5 is provided between the heat dissipation mounting seat 2 and the lens mounting seat 3. The horizontal side of the first L-shaped bracket 5 is provided between the heat dissipation mounting seat 2 and the lens mounting seat 3. The vertical side of the first L-shaped bracket 5 is rotatably connected to the radiator 11.

[0023] A second L-shaped bracket 17 is provided outside the vertical side of the first L-shaped bracket 5 . One side of the second L-shaped bracket 17 is rotatably connected to the vertical side of the first L-shaped bracket 5 , and the other side of the second L-shaped bracket 17 is bent toward the radiator 11 .

[0024] A first rotating shaft 8 is provided on the outer side of the other side of the second L-shaped bracket 17 . The first rotating shaft 8 is connected to the first servo motor 13 via a coupling 6 .

[0025] A first servo reducer 12 is provided at the output end of the first servo motor 13 , and the first servo motor 13 is connected to the coupling 6 and the first rotating shaft 8 via the first servo reducer 12 .

[0026] In this way, the first servo motor 13 drives the first rotating shaft 8 to rotate through the coupling 6. Since the first rotating shaft 8 is fixed to the second L-shaped bracket 17, the first servo motor 13 can drive the first L-shaped bracket 5 fixed to the second L-shaped bracket 17. Since the first L-shaped bracket 5 is fixedly connected to the laser emitter 1 and the radiator 11, the first servo motor 13 drives the first L-shaped bracket 5, the second L-shaped bracket 17, the laser emitter 1 and the radiator 11 to rotate as a whole around the first rotating shaft 8 through the coupling 6.

[0027] The coupling 6 is provided with a servo motor mounting seat 4 on its outer shell, and a mounting seat 10 is provided at the bottom of the servo motor mounting seat 4 .

[0028] At the same time, a plurality of threaded holes are provided on the mounting base 10 , so that the laser head of the present invention can be detachably mounted as a whole through the mounting base 10 and the plurality of threaded holes on the mounting base 10 .

A synchronous belt is provided outside the second servo motor 19 and the synchronous wheel 14. A second rotating shaft 9 is provided inside and in front of the synchronous wheel 14. The synchronous wheel 14 is rotatably connected to the second L-shaped bracket 17 through the second rotating shaft 9.

[0033] In this way, the output end of the second servo motor 19 drives the synchronous wheel 14 through the synchronous belt. Since the synchronous wheel 14 is rotationally connected to the second L-shaped bracket 17, the second servo motor 19 can drive the laser emitter 1 and the radiator 11 on the first L-shaped bracket 5 to swing back and forth relative to the second L-shaped bracket 17.

[0034] A waist-shaped limiting hole 20 is formed on the second L-shaped bracket 17 , and a limiting rod 21 is provided on the outer side of the vertical side of the first L-shaped bracket 5 . The limiting rod 21 is embedded in the limiting hole 20 .
