The telescopic assembly 2 also includes a plurality of guide connecting rods 22, one end of each of the plurality of guide connecting rods 22 is connected to the telescopic end 21. The tying claws 3 are hinged and distributed along the circumference of the telescopic end 21; the tying claws 3 group includes a plurality of tying claws 3, the tying claws 3 have a first end 31 and a second end 32, the first end 31 is hinged to the tying end 11 at one point, the first end 31 is hinged to the other end of the guide link 22 at another point, and the second end 32 extends outward, the plurality of tying claws 3 are distributed along the circumference of the tying end 11, the plurality of tying claws 3 form an annular enclosure, the elastic rope sleeve is arranged on the periphery of the annular enclosure, and the middle of the annular enclosure is used to place the plants to be tied;

[0050] The tying claw 3 can be placed in a retracted state or an open state. When the tying claw 3 is placed in the open state, the telescopic end 21 protrudes outward to drive the guide link 22, so that the second end 32 rotates outward relative to the first end 31, and the radial size of the annular enclosure circle gradually increases from the inside to the outside to limit the elastic rope at the connection between the first end 31 and the tying end 11. When the tying claw 3 is placed in a retracted state, the telescopic end 21 retracts inward to drive the guide link 22, so that the second end 32 rotates inward relative to the first end 31, and the radial size of the annular enclosure circle gradually decreases from the inside to the outside. The elastic rope detaches from the second end 32 under the action of elasticity to be tied to the plant.

[0051] In this embodiment, the movable seat 1 has a bundling end 11, and the bundling end 11 is a cylindrical structure with a cavity inside. Figure 3 and Figure 4 As shown, the cavity inside the tying end 11 is recorded as an active cavity 12, and the active cavity 12 has an opening facing outward. The telescopic end 21 is placed in the active cavity 12, and the telescopic end 21 is connected to the tying claw 3 through the opening facing outward. Specifically, the telescopic assembly 2 includes a plurality of guide links 22, each of which is used to connect a tying claw 3, and the tying claw 3 is also hinged to the tying end 11, that is, the tying claw 3 is distributed in the circumference of the active cavity 12, then when the telescopic end 21 retracts inward, the guide link 22 will drive the tying claw 3 to rotate toward the inside of the tying end 11, and when the telescopic end 21 protrudes outward, the guide link 22 will drive the tying claw 3 to rotate toward the outside of the tying end 11.

[0052] Specifically, the tying claw 3 includes a first end 31 and a second end 32, wherein the first end 31 is an end for being hinged with the tying end 11 and the guide link 22, and the second end 32 is an end hanging outward, that is, an end where the elastic rope needs to roll down in the end, and the tying claw 3 can be a sheet-like structure, which can be set according to actual needs. It should be noted that the point where the first end 31 is hinged with the tying end 11 does not overlap with the point where the first end 31 is hinged with the guide link 22, so that the guide link 22 can realize the rotational guidance of the tying claw 3.

[0053] Utilizing this structure, the present embodiment provides a plurality of tying claws 3 and a plurality of guide links 22. The plurality of tying claws 3 are provided along the circumference of the tying end 11. The guide links 22 correspond to the tying claws 3 and are provided on the circumference of the telescopic end 21. The plurality of tying claws 3 form a variable diameter annular enclosure ring, that is, when the elastic rope is sleeved on the outside of the tying claws 3, there is a connecting fulcrum between the elastic rope and the plurality of tying claws 3, and the plurality of connecting fulcrums form a virtual annular enclosure ring. By adjusting the position of the tying claws 3, the diameter of the annular enclosure ring can be changed, and the elastic force of the elastic rope can be reduced accordingly when the annular enclosure ring changes diameter, until the annular enclosure ring is smaller than the diameter of the elastic rope in the natural stretched state, and the elastic rope will fall off the annular enclosure ring. In this dynamic change state, the elastic rope will move forward under the action of inertia, and thus be sleeved on the end of the plant to be tied.

[0054] It is understandable that part of the plants to be bundled are placed in the annular enclosure, that is, the coverage area of ​​the bundling claws 3. This method allows the elastic rope to be tied above the end of the plant, preventing the elastic rope from falling off directly from the end of the plant after bundling, thereby improving the bundling efficiency.

[0055] This embodiment realizes automatic bundling of plants and rationally utilizes the tension change characteristics of the elastic rope, solving the problem that the elastic rope bundling of plants needs to rely on manual labor. The plant harvester extended from this embodiment can realize fully automatic harvesting and bundling of plants, thereby improving the harvesting efficiency of plants and saving manpower.

[0057] In this embodiment, the first protrusion 33 is arranged in the area of ​​the binding claw 3 close to the first end 31, and can be specifically as follows: Figure 3 As shown, when the tying claws 3 are in the open state, the first protrusion 33 abuts against the outer surface of the tying end 11 to prevent the tying claws 3 from being over-opened and causing the elastic rope to roll directly in a direction away from the second end 32 .

[0058] See also Figure 3 and Figure 4 In some embodiments, the telescopic assembly 2 further includes a first drive unit 23 and a push rod 24. The first drive unit 23 is arranged on the movable seat 1. The push rod 24 is connected to the output end of the first drive unit 23 by transmission. The end of the push rod 24 has a telescopic end 21. Specifically, the first drive unit 23 can be a cylinder, an electric cylinder, etc. with a telescopic function, or can achieve the function of reciprocating telescopic by means of a transmission connection between a servo motor and a screw rod. The push rod 24 is a slender rod, which is connected to the output end of the first drive unit 23 by transmission. The output end of the first drive unit 23 can drive the push rod 24 to telescope. The telescopic end 21 is provided at the end of the push rod 24 hanging outward. As a preferred embodiment, a disc can be set on the end of the push rod 24 hanging outward, and a plurality of guide connections are connected in the circumferential direction of the disc. The center point of the disc is connected to the end of the push rod 24, and the telescopic end 21 is also this disc structure. Optionally, the movable cavity 12 can pass through the movable seat 1 , and the output end of the first driving unit 23 reaches the bundling end 11 through the movable cavity 12 . This method can fully utilize the internal space of the movable seat 1 .

[0059] See also Figure 1 and Figure 4 In some embodiments, a first long groove is provided on the movable seat 1, and the first long groove extends along the axial direction of the movable seat 1. A plurality of elastic ropes are provided on the outer periphery of the movable seat 1.

[0060] In this embodiment, the movable seat 1 is provided with a first long groove. Specifically, the first long groove is provided on the outer surface of the movable seat 1, and the first long groove extends along the axial direction of the movable seat 1, preferably extending to the bundling end 11, but does not penetrate the bundling end 11, and the first conveying rod 5 is provided in the first long groove. Figure 1 and Figure 4 As shown, part of the first conveying rod 5 protrudes out of the outer surface of the movable seat 1, and when the elastic rope is sleeved on the outer periphery of the movable seat 1, there is a contact point with the outer surface of the first conveying rod 5. The second driving unit 4 can be a screw motor, a servo motor, etc., which is not limited in this embodiment. The second driving unit 4 is connected to the first conveying rod 5 in a transmission manner and can drive the first conveying rod 5 to rotate.

[0061] Furthermore, a spiral flange 51 is provided on the outer wall of the first conveying rod 5. The characteristics of the spiral flange 51 enable the outer wall of the first conveying rod 5 to have multiple single-turn and continuous annular protrusions, and a groove 52 is provided between two adjacent annular protrusions. When the elastic rope sleeve is arranged on the periphery of the movable seat 1, it can be placed in this groove 52. When the first conveying rod 5 rotates, it drives the groove 52 to be delivered forward, thereby realizing the dynamic operation of the elastic rope automatically approaching the bundling end 11, that is, after the elastic rope of the bundling end 11 is bundled, the next elastic rope can be timely supplemented to the connection between the bundling end 11 and the bundling claw 3, thereby realizing the automatic delivery effect of the elastic rope.

[0062] See also Figure 4 In some embodiments, there are two first long grooves, which are arranged on both sides of the movable seat 1, two second driving units 4, two first conveying rods 5, one second driving unit 4 is in transmission connection with one first conveying rod 5, and one first conveying rod 5 is placed in one first long groove. This method allows both ends of the elastic rope to be pushed forward evenly when the first conveying rod 5 is transferred, avoiding the problem that one end of the elastic rope is stuck on the movable seat 1 and entangled with other elastic ropes.

[0063] See also Figure 3 In some embodiments, the outer wall of the tying end 11 has a tapered guide surface 111 for guiding the elastic cord. In some preferred embodiments, the tapered guide surface 111 is slightly axially recessed toward the center of the movable seat 1, so that the elastic cord can more easily slide to the connection between the tying end 11 and the tying claw 3 under the action of inertia, and avoid being stuck on the tapered guide surface 111.

[0064] See also Figure 2 In some embodiments, the guide link 22 has a first hinged portion 221, a connecting portion 222, and a second hinged portion 223 connected in sequence.
