At the same time, it is difficult for mobile spraying machines to adapt to the flexible conversion between different widths of ridges, which easily causes damage to non-target areas (such as adjacent crops). For crops with different heights, there is a lack of an effective height adjustment function in the vertical direction, resulting in uneven and incomplete drug coverage. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0031] Referring to Figures 1 - 7 , a fully automatic weeding robot includes two relatively arranged automatic moving parts 1. The automatic moving part 1 can be remotely controlled under the cooperation of components such as electric drive, without manual pushing, saving manpower. The top of the automatic moving part 1 is bolted with a disassembly and assembly seat 2, and the disassembly and assembly seat 2 can be quickly disassembled and assembled, facilitating the disassembly, maintenance and repair of the liquid storage bin 3. The top of the disassembly and assembly seat 2 is fixedly connected with a liquid storage bin 3, and the liquid storage bin 3 is used to store pesticides required for spraying. A lifting seat 4 is arranged directly above the liquid storage bin 3, and a power pump 5 is fixed on the lifting seat 4. The power pump 5 provides power for spraying the spraying head 6. The power pump 5 pumps and sprays the pesticides in the liquid storage bin 3. A plurality of spraying heads 6 are fixed on the power pump 5. A second transverse moving main seat 12 and a pair of first transverse moving main seats 7 are arranged on the opposite sides of the two automatic moving parts 1. Transverse moving auxiliary plates 8 are slidably arranged on both the first transverse moving main seat 7 and the second transverse moving main seat 12, and the transverse moving auxiliary plates 8 are fixedly connected with the automatic moving part 1. A plurality of monitoring sensors 9 are fixedly installed on the automatic moving part 1; the monitoring sensors 9 are used to detect pests on crops and vegetation, and pests attached to the back of the leaves of the vegetation can also be detected. After the pests are detected, under a pre-set program, after the lifting seat 4 moves vertically, the spraying head 6 sprays pesticides to kill the pests and prevent them from harming the crops.
[0032] It further includes:
[0033] A driving component for adjusting the relative distance between the two automatic moving parts 1;
[0034] A lifting component for adjusting the height of the lifting seat 4;
[0035] The laser weeding assembly 19 is used to emit laser for burning and weeding operations. When the camera assembly detects pests, the laser weeding assembly 19 can emit laser for burning and weeding. The laser weeding assembly 19 generally consists of multiple key components, including a single-chip microcomputer control system, a laser emitter, and a power supply, etc. The single-chip microcomputer control system is responsible for receiving signals from sensors and judging whether to emit laser according to preset parameters. At the same time, it can also adjust parameters such as laser power, scanning angle, and scanning speed to meet the needs of different farmlands. The single-chip microcomputer control system, the laser emitter, and the power supply are existing mature technologies, so no more description will be given.
[0036] The camera assembly is convenient for accurately identifying weeds before the pesticide spraying head 6 sprays pesticides for weeding and the laser weeding assembly 19 emits laser for weeding.
[0037] A power supply group 10 and two moving wheels 11 are arranged on the automatic moving part 1. The power supply group 10 and the moving wheels 11 are electrically connected, and the power supply group 10 provides moving power for the moving wheels 11. The power supply group 10 includes components such as a battery, which is an existing mature technology. The main purpose is to realize the rotation of the moving wheels 11, so no more description will be given here.
[0038] The driving assembly includes a concave bottom plate 121 fixedly connected to the bottom of the second transverse moving main seat 12. An L-shaped rod 122 is fixedly connected to the bottom of the transverse moving sub-plate 8. A rack 123 is fixedly connected to the side wall of the L-shaped rod 122 opposite to the concave bottom plate 121. A transverse moving rocking wheel 124 is fixedly connected to the concave bottom plate 121. The output end of the transverse moving rocking wheel 124 is fixedly connected to a gear 125, and the gear 125 meshes with the rack 123. The transverse moving rocking wheel 124 drives the gear 125 to rotate, and the gear 125 drives the rack 123 to move horizontally. Two transverse moving rocking wheels 124 can be started simultaneously, or one of the transverse moving rocking wheels 124 can be started alone to achieve two different effects. The first is that the two automatic moving parts 1 move synchronously relatively or away from each other. The second is that one of the automatic moving parts 1 moves relative to the other automatic moving part 1, making the overall adjustment of the device more flexible.
[0039] Both of the two transverse moving rocking wheels 124 are arranged on the concave bottom plate 121, and the output ends of the two transverse moving rocking wheels 124 are arranged in opposite directions. The transverse moving sub-plates 8 on the first transverse moving main seat 7 and the second transverse moving main seat 12 are both arranged in pairs, and the L-shaped rod 122 is fixedly arranged on the bottom surface of one of the transverse moving sub-plates 8 in the same pair. Multiple bottom teeth 126 are arranged at the bottom of the L-shaped rod 122. The setting of the bottom teeth 126 is to prevent the rack 123 and the L-shaped rod 122 from touching weeds or vegetation when the automatic moving part 1 moves, making it difficult to move the whole device. The bottom teeth 126 are convenient for horizontally cutting weeds, etc., facilitating the smooth movement of the whole device.
[0040] Both the first horizontal movement main seat 7 and the second horizontal movement main seat 12 are provided with sliding openings facilitating the sliding of the horizontal movement auxiliary plate 8. A retaining opening 14 is arranged at the port of the sliding opening, and a protrusion 13 is arranged at the end of the horizontal movement auxiliary plate 8, and the protrusion 13 and the retaining opening 14 are arranged correspondingly. The retaining opening 14 and the protrusion 13 are arranged to prevent the horizontal movement auxiliary plate 8 from falling off relative to the first horizontal movement main seat 7 or the second horizontal movement main seat 12.
[0041] The lifting assembly includes grooves 16 formed on the opposite side walls of the automatic moving part 1 and the lifting seat 4, and the grooves 16 are arranged in pairs. A bidirectional lead screw 161 is rotatably connected in the groove 16 on the lifting seat 4, and a limiting slide bar 162 is fixedly connected in the remaining lifting grooves 16. The arrangement of the limiting slide bar 162 not only enables the moving seat 163 to stably move along the axial direction of the bidirectional lead screw 161, but also makes the whole lifting assembly more evenly stressed and the overall appearance more coordinated. A moving seat 163 slides in the groove 16, and the moving seats 163 are arranged in pairs. One pair of moving seats 163 is threadedly connected with the bidirectional lead screw 161, and the remaining three pairs of moving seats 163 are slidably connected with the limiting slide bar 162. A lifting handwheel 164 for driving the bidirectional lead screw 161 to rotate is fixedly connected to the lifting seat 4. A short shaft 165 is fixedly connected to the moving seat 163, and a traction rod 166 is rotatably connected to the short shaft 165, and the traction rods 166 are arranged in a cross shape.
[0042] Two cross - arranged traction rods 166 are rotatably connected to the same limiting column 167. Anti - detachment blocks are fixed at both ends of the limiting column 167. Two pairs of cross - arranged traction rods 166 are respectively arranged on both sides of the liquid storage bin 3. The arrangement of the limiting column 167 prevents the two cross - arranged traction rods 166 from deviating relatively.
[0043] The camera assembly includes a pair of vertical rods 20 fixedly connected to the top of the second horizontal movement main seat 12. A liquid - blocking plate 201 is fixedly connected to the top of the vertical rod 20. The liquid - blocking plate 201 is used to prevent impurities in the air or sprayed pesticides from adhering to the hemispherical camera 202, affecting the imaging operation of the hemispherical camera 202. The hemispherical camera 202 is fixedly connected to the liquid - blocking plate 201.
[0044] A fixing groove 17 facilitating the fixing of the power pump 5 is formed at the top of the lifting seat 4. A plurality of through - openings 18 are formed on the fixing groove 17. A liquid suction pipe 15 is fixedly and penetratingly installed at the bottom of the through - opening 18, and the bottom end of the liquid suction pipe 15 is arranged inside the liquid storage bin 3.
[0045] The functional principle of the present invention can be elaborated through the following operation modes:
[0046] First, add pesticides or herbicides to the liquid storage tank 3 according to the required ratio. Then, fix the disassembly and assembly seat 2 on the top of the automatic moving part 1 through bolts to ensure a stable structure. Next, install the power pump 5 on the lifting seat 4 and connect multiple spray heads 6 to the power pump 5. At the same time, check whether all monitoring sensors 9 are in normal working condition, including monitoring weeds, pests, and environmental conditions in the farmland, etc.
[0047] Turn on the power supply group 10 to provide power support for the two moving wheels 11, enabling the entire device to move freely.
[0048] After the hemispherical camera 202 observes and identifies weeds, the power pump 5 operates. It sprays the pesticides in the lifting seat 4 through the spray heads 6, and the pesticides are sprayed onto the weeds, thus achieving the removal of weeds. At the same time, laser weeding can also be carried out by starting the laser weeding component 19.
[0049] According to actual needs, use the driving component to adjust the relative distance between the two automatic moving parts 1; specifically: start the transverse movement handwheel 124, the transverse movement handwheel 124 drives the gear 125 to rotate, the gear 125 drives the rack 123 to move horizontally, the rack 123 drives the L-shaped rod 122 to move horizontally, the L-shaped rod 122 drives the transverse movement auxiliary plate 8 to slide horizontally on the transverse movement main seat 7, and the transverse movement auxiliary plate 8 drives the automatic moving part 1 to move horizontally, thereby flexibly adjusting the relative distance between the two automatic moving parts 1.
[0050] Use the lifting component to adjust the height of the lifting seat 4 to adapt to crops of different heights; specifically: start the lifting handwheel 164, the lifting handwheel 164 drives the bidirectional lead screw 161 to rotate, the bidirectional lead screw 161 drives the two moving seats 163 threadedly connected to it to move horizontally synchronously, drives the traction rod 166 to rotate, thereby adjusting the height of the lifting seat 4.
[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
