[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] See also Figures 1 to 9 A weeder for urban greening management in this embodiment includes a mounting plate 10, a weeding head 20 for weeding is fixedly connected to the bottom of the mounting plate 10, a telescopic mechanism 30 for extending the length of the weeding head 20 is provided on one side of the mounting plate 10, and collision avoidance mechanisms 40 for preventing the weeding head 20 from contacting with the roots of shrubs are also provided on both sides of the mounting plate 10, and a picking mechanism 50 for preventing the weeding head 20 from contacting with stones is also provided on the side of the mounting plate 10 away from the telescopic mechanism 30.

[0031] The telescopic mechanism 30 includes an outer shell 301 arranged on the side of the mounting plate 10, a sliding rod 302 is fixedly connected inside the outer shell 301, a moving block 304 is slidably connected outside the sliding rod 302, a screw rod 303 is also rotatably connected inside the outer shell 301, the screw rod 303 is threadedly connected to the moving block 304, a motor 310 is fixedly connected outside the outer shell 301, an output end of the motor 310 is fixedly connected to the screw rod 303, and a collecting mechanism 60 for cleaning weeds is arranged at the bottom of the outer shell 301.

[0032] The telescopic mechanism 30 further includes a connecting plate 305 fixedly connected to the top of the moving block 304. The connecting plate 305 extends from the side of the outer housing 301 to the outside of the outer housing 301. One end of the connecting plate 305 away from the moving block 304 is fixedly connected to a U-shaped plate 306. One end of the U-shaped plate 306 away from the connecting plate 305 is fixedly connected to an L-shaped plate 308. The front end of the L-shaped plate 308 is fixedly connected to the mounting plate 10.

[0033] A top cover 307 is snap-connected to the top of the outer housing 301, and the side of the top cover 307 enters the groove of the U-shaped plate 306. A supporting belt wheel 309 is fixedly connected to the side of the outer housing 301. The supporting belt wheel 309 is in rolling connection with the bottom of the L-shaped plate 308.

[0034] During specific operation, when removing weeds deep in the bushes, the motor 310 drives the screw 303 to rotate. The rotating screw 303 drives the moving block 304 to move in the outer housing 301. The moving block 304 drives the L-shaped plate 308 to move horizontally through the connecting plate 305 and the U-shaped plate 306. When the L-shaped plate 308 moves, it drives the weeding cutter head 20 on the mounting plate 10 to extend in length, so as to extend the weeding cutter head 20 deep into the bushes. By adjusting the position of the cutter head, it can easily enter the interior of the bushes, reducing the need for manual cleaning and greatly improving the work efficiency. When the L-shaped plate 308 moves, the L-shaped plate 308 rolls on the supporting belt wheel 309. At the same time, the top cover 307 and the U-shaped plate 306 cooperate with each other to prevent weeds from falling into the interior of the outer housing 301. By designing a mechanism to prevent foreign objects such as weeds from entering the equipment interior, the key components can be protected from wear and corrosion.

[0035] The collision avoidance mechanism 40 includes mounting rods 401 vertically and slidably connected to both sides of the mounting plate 10. Arc-shaped protective covers 402 are fixedly connected to both ends of the mounting rods 401. A tension spring 403 is also sleeved outside the mounting rods 401. The tension spring 403 is located above the mounting plate 10.

[0036] A connecting rod 404 is fixedly connected to the top of the protective cover 402. A roller 405 is rotatably connected to the middle of the connecting rod 404. A trapezoidal block 406 is fixedly connected to the top of the top cover 307 directly below the roller 405.

[0037] During specific operation, when the mounting plate 10 and the weeding cutter head 20 extend in length, the roller 405 slides off the trapezoidal block 406. At this time, under the pulling of the tension spring 403, the mounting rods 401 drive the protective covers 402 to move downward to both sides of the weeding cutter head 20, using the protective covers 402 to prevent the cutter head from contacting the roots of the bushes, thereby protecting the cutter head and avoiding damage to the cutter head.

[0038] The picking mechanism 50 includes a mounting frame 501 fixedly connected to the front of the protective cover 402 , a vertical plate 502 is fixedly connected to the outside of the mounting frame 501 , a collecting frame 503 is fixedly connected to the bottom of the vertical plate 502 , and a scraper 504 is fixedly connected to the front of the collecting frame 503 .

[0039] A round rod 505 is also fixedly connected to the front of the collection frame 503, and a plurality of baffle rods 506 are sleeved on the outside of the round rod 505. A limiting rod 508 is also fixedly connected to the outside of the collection frame 503, and a torsion spring 507 is sleeved inside each baffle rod 506. One end of the torsion spring 507 is fixedly connected to the baffle rod 506, and the other end of the torsion spring 507 is fixedly connected to the round rod 505.

[0040] During specific operation, when the protective cover 402 moves downward, the protective cover 402 drives the vertical plate 502 and the collection frame 503 to move downward synchronously. When the weeding cutter head 20 is extended, the shovel blade 504 at the front of the collection frame 503 contacts the stones on the ground and shovels the stones into the collection frame 503. When the stones contact the baffle rod 506, the baffle rod 506 deflects. At this time, the torsion spring 507 accumulates force. When the stones enter the collection frame 503, the torsion spring 507 drives the baffle rod 506 to reset, thereby preventing the stones in the collection frame 503 from returning to the ground, and also preventing the weeding cutter head 20 from contacting the stones and causing damage to the cutter head.

[0041] The collecting mechanism 60 includes a collecting bin 601 fixedly connected to the bottom of the outer shell 301, a bracket 602 fixedly connected to the front opening of the collecting bin 601, a rotating shaft 603 rotatably connected to the middle of the bracket 602, a shifting rod 604 is fixedly connected to the outer side of the rotating shaft 603 in a ring shape, and a shifting mechanism 70 for gathering the scattered weeds is provided at one end of the bracket 602 away from the collecting bin 601.

[0042] During operation, the weeds are harvested and the rotating shaft 603 drives the lever 604 to rotate synchronously. The rotating lever 604 throws the weeds into the collection bin 601 to prevent the weeds from piling up in the bushes and facilitate quick collection of the weeds.

[0043] The toggling mechanism 70 includes a connecting shaft 702 vertically rotatably connected to the bracket 602, a swing rod 701 is fixedly connected to the bottom of the connecting shaft 702, a push rod 703 is hinged to the top of the connecting shaft 702, a connecting rod 705 is hinged to the other end of the push rod 703, a disk 704 is fixedly connected to the end of the connecting rod 705 away from the push rod 703, the disk 704 is fixedly connected to the rotating shaft 603, and the rotating shaft 603 is concentrically connected to the disk 704, the disk 704 and the connecting rod 705 are eccentrically connected, and a servo mechanism 80 for unidirectional toggling weeds is arranged at the bottom of the swing rod 701.

[0044] During specific operation, when the rotating shaft 603 rotates, the rotating shaft 603 drives the disc 704 to rotate, and the rotating disc 704 drives the connecting rod 705 to rotate. The connecting rod 705 drives the swing rod 701 to swing back and forth through the push rod 703. When the swing rod 701 swings back and forth, the harvested weeds are concentrated at the center position of the rotating shaft 603, so that the weeds can be quickly collected.

[0045] The servo mechanism 80 includes a receiving groove 801 opened at the bottom of the swing rod 701. A mounting shaft 802 is fixedly connected inside the receiving groove 801 and is close to the side wall of the swing rod 701. A plurality of gear rods 803 are sleeved outside the mounting shaft 802 and extend to the outside of the receiving groove 801.

[0046] During specific operation, when the two swing arms 701 approach each other, the gear rod 803 is blocked by the side wall of the receiving groove 801, and the gear rod 803 rotates at a small angle. At this time, the gear rod 803 can move the weeds to the center position of the rotating shaft 603. When the two swing arms 701 move away from each other, the gear rod 803 is far away from the side wall of the other side of the receiving groove 801. At this time, the gear rod 803 rotates at a large angle, which makes it impossible for the gear rod 803 to move the weeds.

[0047] Working principle: When clearing weeds deep in the bushes, the telescopic mechanism 30 is used to extend the length of the weeding cutter head 20, and the collision avoidance mechanism 40 provides protection for the weeding cutter head 20 to prevent the cutter head from contacting the roots of the bushes. The picking mechanism 50 is used to collect stones to protect the cutter head. After harvesting the weeds, the toggle mechanism 70 first concentrates the weeds at the center of the rotating shaft 603, and then the collecting mechanism 60 collects the weeds into the collecting bin 601. When the toggle mechanism 70 is working, the servo mechanism 80 controls the swing rod 701 to only collect the weeds together.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
