[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0033] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a laser weeding device that can accurately identify weeds includes a weeding machine main body 1, a scanning camera 2 and a cutting component 3. The scanning camera 2 is rotatably installed on the side of the weeding machine main body 1, and the cutting component 3 is fixedly installed on the bottom end of the side of the weeding machine main body 1. A blowing mechanism 4 is fixedly installed on the side of the cutting component 3. The blowing mechanism 4 includes an air outlet 41, an air supply pipe 42, a connecting block 43 and a fixing component 44. The connecting block 43 is fixedly installed on the side of the cutting component 3, and the fixing component 44 is fixedly installed on the side of the connecting block 43. The air outlet 41 is fixedly installed inside the fixing component 44, and the air supply pipe 42 is fixedly installed at the end of the air outlet 41. The air outlet 41 can move synchronously with the cutting component 3 to touch the crops and weeds in the target area, forcing the crops and weeds to expose their roots for quick cutting. A collecting mechanism 5 is fixedly installed inside the weeding machine main body 1.

[0034] During use, the main body 1 of the weeding machine is placed at the target position, and then the internal components of the main body 1 of the weeding machine are operated to drive the main body 1 of the weeding machine to move stably in the field. During the movement, the main body 1 of the weeding machine and the cutting component 3 are used to stably and accurately scan the impurities in the field, and then the internal components of the cutting component 3 are used to quickly cut the weeds. When the weeds and seedlings are too close to each other and the internal components of the cutting component 3 cannot cut the roots of the weeds, the internal components of the blowing mechanism 4 can be operated, and the air pipe 42 can transport a certain amount of air and spray it through the air outlet 41. The use of the connecting block 43 and the fixing component 44 can ensure that the aiming angle of the air outlet 41 is consistent with the aiming angle of the cutting component 3, and the part detected by the cutting component 3 can be blown to blow all the seedlings and weeds to the side away from the main body 1 of the weeding machine, so that the two appear in a tilted state. At this time, the roots of the weeds can be cut by using the cutting component 3, thereby ensuring the stability of the equipment during operation.

[0035] By the attached Figure 5 As shown, in this embodiment, the fixing assembly 44 also includes a bottom clamping plate 441, a side cover plate 442, a plug-in groove 443, a fixing screw 444 and a fixing nut 445.

The fixing nut 445 is continuously moved along the threaded outer wall of the fixing screw 444, so that the distance between the side cover plate 442 and the bottom clamp plate 441 can be adjusted, so that the position of the air outlet 41 itself is fixed, and the air outlet 41 can move synchronously with the cutting component 3, so as to facilitate the blowing of the weeds detected by the cutting component 3.

[0037] By the attached Figure 6 As shown, in this embodiment, the blowing mechanism 4 also includes a support seat 45, a suction pump body 46 and a suction assembly 47.

[0038] During use, the surrounding air can be sucked by using and running the suction pump body 46, and then input into the air outlet 41 through the air supply pipe 42. The target area can be blown through the air outlet 41 to facilitate the operation of the cutting component 3. The installation of the suction component 47 can suck the surrounding air, and when in use, it can suck the weeds after partial cutting, quickly complete the collection of waste, and then input the weeds into the collection mechanism 5, simplifying the overall operation steps.

[0042] During use, the mobile power source inside the component is used to provide power for the operation of the equipment. Through the use of the rotating seat 31 and the multi-directional rotating arm 32, the angle of the laser cutter 33 can be flexibly and multi-angle adjusted and changed. When in use, the weeds and crops in the target area are photographed through the optical shutter, and the photographed data is transmitted to the inside of the weeding machine body 1. The photographed images are analyzed and processed through the internal circuit elements to distinguish between weeds and crops. The laser can select weeds according to the analyzed data and cut the impurities, allowing the laser cutter 33 to cut the weeds in the field, and the auxiliary equipment completes the operation quickly and stably.

The mounting block 34 is fixedly mounted on the side of the laser cutter 33, and the laser scanner 35 is fixedly mounted inside the mounting block 34. The laser scanner 35 is electrically connected to the internal circuit of the main body 1 of the weeding machine.

[0044] During use, the laser scanner 35 can be used to comprehensively scan and analyze various weeds in the field, quickly and accurately identify the weeds, and provide calibration points for the subsequent operation of the laser cutter 33, so that the laser cutter 33 can aim at the roots of the weeds for cutting.

[0045] By the attached Figure 4 As shown, in this embodiment, the laser cutter 33 includes a laser emitter 331, a laser lens 332, an energy storage battery 333 and a shell 334.

[0046] By the attached Figure 7 As shown, in this embodiment, the collecting mechanism 5 also includes a protective shell 51, a filter baffle 52, a sliding groove 53 and a collecting assembly 54. The filter baffle 52 is fixedly installed on the side of the support seat 45. The filter baffle 52 can filter impurities entering the collecting mechanism 5. The protective shell 51 is fixedly installed inside the main body 1 of the weeding machine. A sliding groove 53 is opened inside the protective shell 51. The collecting assembly 54 is slidably installed inside the sliding groove 53.

[0047] During use, the operation of the suction pump body 46 can be used to suck the weeds at the end of the suction component 47, and then the weeds can be collected into the protective shell 51. The establishment of the filter baffle 52 fits the air inlet of the suction pump body 46 with the filter baffle 52. Through the cooperation of the filter baffle 52, the weeds sucked into the collection mechanism 5 can be filtered to prevent the weeds from entering the suction pump body 46 and the air pipe 42 and affecting the stability of the two components, so that the weeds automatically fall into the sliding groove 53.

[0049] During use, by using the collection bin 541 and the collection trough 542, the weeds collected by the upper part can be quickly concentrated and all collected into the collection bin 541. The presence of the extraction plate 543 can quickly move the entire collection component 54, making it convenient for the staff to extract the collection component 54 and collect the weeds inside the collection bin 541, thereby speeding up the work efficiency of the equipment itself.

[0050] By the attached Figure 8 As shown, in this embodiment, the weeding machine main body 1 also includes a robot frame 11, a photovoltaic panel 12 and a driving wheel 13.
