[0044] The collecting mechanism 60 comprises a collecting bin 601 fixedly connected to the bottom of the outer shell 301, a support 602 fixedly connected to the front opening of the collecting bin 601, a rotating shaft 603 rotationally connected to the middle of the support 602, a pushing rod 604 fixedly connected in an annular shape outside the rotating shaft 603, and a pushing mechanism 70 arranged at the end of the support 602 away from the collecting bin 601 and used for concentrating the scattered weeds.

[0045] In specific work, the weeds after being cut are driven by the rotating shaft 603 to rotate synchronously, the weeds are thrown into the collecting bin 601 by the rotating pushing rod 604, the weeds are prevented from being accumulated in the shrubs, and the weeds are also conveniently and quickly collected.

[0046] The pushing mechanism 70 comprises a connecting shaft 702 vertically rotationally connected with the support 602, a swing rod 701 fixedly connected to the bottom of the connecting shaft 702, a push rod 703 hingedly connected to the top of the connecting shaft 702, a connecting rod 705 hingedly connected to the other end of the push rod 703, a disc 704 fixedly connected to the end of the connecting rod 705 away from the push rod 703, the disc 704 being fixedly connected with the rotating shaft 603 and being concentrically connected with the rotating shaft 603, the disc 704 and the connecting rod 705 being eccentrically connected, and a servo mechanism 80 arranged at the bottom of the swing rod 701 and used for unidirectionally pushing the weeds.

[0047] 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, thereby facilitating the rapid collection of the weeds.

[0048] 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 the mounting shaft 802 is close to the side wall of the swing rod 701. A plurality of gear rods 803 are sleeved on the outside of the mounting shaft 802, and the gear rods 803 extend to the outside of the receiving groove 801.

[0049] 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 rotation angle of the gear rod 803 is small. 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 other side wall of the receiving groove 801. At this time, the rotation angle of the gear rod 803 is large, which makes it impossible for the gear rod 803 to move the weeds.

[0050] Working principle:

[0051] When clearing weeds deep in the bushes, the telescopic mechanism 30 is used to extend the length of the weeding cutter head 20. At the same time, 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 arm 701 to only collect the weeds together.

[0052] 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, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these 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 various embodiments of the present invention.
