[0026] A rotating disk 2 is arranged on the rotating table 1, and the rotating disk 2 is rotatably connected to the rotating table 1, so that the rotating disk 2 can rotate freely along its central axis; an L-shaped sliding track 21 is arranged on the rotating disk 2, and the sliding track 21 is a through groove structure, which opens up the two sides of the rotating disk 2; a guide rod 3 is arranged in the sliding track 21, and the guide rod 3 is vertically arranged through the sliding track 21, so that when the guide rod 3 rotates around the central axis of the rotating disk 2, the rotating disk 2 will also rotate together under the limiting action of the sliding track 21, and when the rotating disk 2 does not rotate, the guide rod 3 can also slide horizontally within the range limited by the sliding track 21.

[0027] A wire groove is provided on one side of the rotating table 1, and a wire groove cover 11 is provided on the wire groove; a wire drum 15 can be installed in the wire groove, such as Figure 2 As shown, a binding wire 4 is wound around the wire drum 15 for binding vegetables; a rotating shaft is arranged on the wire drum 15 along the central axis in the length direction, and a through hole matching the rotating shaft is arranged on the rotating platform 1; a hand crank 14 is arranged through the through hole, and the hand crank 14 is fixedly connected to the rotating shaft, so that the wire drum can be rotated by rotating the hand crank 14, as shown in FIG. Figure 3 The inner side of the rotating table 1 is provided with a channel that cooperates with the wire groove, so that the binding wire 4 wound on the wire drum 15 can extend from the inner side of the rotating table 1, such as Figure 4 shown.

[0028] An elastic connector 5 is provided on the bottom surface of the rotating disk 2, and the elastic connector 5 is connected to the guide rod 3 to provide a certain elastic connection effect for the guide rod 3, so that the guide rod 3 can automatically return to a predetermined state when no external force is applied; the specific structure of the elastic connector 5 is as follows: Figure 4 As shown, it includes an elastic connector 5 body fixedly arranged at the bottom of the rotating disk 2, and two telescopic holes are arranged on one side surface of the body facing the guide rod 3, and a horizontal elastic connecting rod 51 and a vertical elastic connecting member 53 are respectively telescopically matched with the two telescopic holes.

[0029] A connecting tube 52 is provided at the end of the horizontal elastic connecting rod 51, and the guide rod 3 is arranged through the connecting tube 52, so that the horizontal elastic connecting rod 51 is connected to the guide rod 3 at a right angle and the guide rod 3 can be telescopically moved up and down; a spring 6 is provided between the horizontal elastic connecting rod 51 and the main body of the elastic connector 5, and the spring 6 is a contraction spring, which continuously applies a pulling force to the connecting tube 52 toward the direction of the main body of the elastic connector 5, that is, toward the central axis of the rotating disk 2; when not affected by external force, the guide rod 3 will slide and contract inward by itself under the action of the horizontal elastic connecting rod 51.

[0030] A vertical through hole is provided at the end of the vertical elastic connector 53, and the guide rod 3 can pass through the through hole and be arranged in cooperation with the vertical elastic connector 53; a spring 6 is sleeved around the through hole on the bottom surface of the vertical elastic connector 53, and the top of the spring 6 is fixedly connected to the bottom surface of the vertical elastic connector 53; an elastic connecting disk 31 is provided on the guide rod 3, and the elastic connecting disk 31 is fixedly connected to the bottom end of the spring 6. The spring 6 is a contraction spring. When not affected by external force, the spring 6 will pull up the guide rod 3 to slide upward; according to the height of the vertical elastic connector 53 and the minimum length of the spring 6, the maximum height of the guide rod 3 can be adjusted so that the maximum height of the guide turntable 33 at the bottom end of the guide rod 3 is the same as the most suitable binding height of the target vegetables.

[0031] A guide ring 32 is provided on the guide rod 3, and the guide ring 32 is located below the elastic connection plate 31; the guide ring 32 is rotatably connected to the guide rod 3, so that the guide ring 32 can rotate freely around the central axis of the guide rod 3; a groove is provided on the side of the guide ring 32, and an anti-friction rotating shaft is horizontally provided between the two inner side walls of the groove; the tying wire 4 passes through the inner side gap of the anti-friction rotating shaft from top to bottom, so that the tying wire is closely attached to the side wall of the guide rod 3, such as Figure 4 As shown; a guide rotary head 33 is provided at the bottom end of the guide rod 3, and the guide rotary head 33, like the guide ring 32, is also rotatably connected to the guide rod 3; an anti-friction rotating shaft is also provided on the guide rotary head 33, and the binding line 4 also passes through the inner gap of the anti-friction rotating shaft; through the guide ring 32 and the guide rotary head 33, the binding line 4 can be made to be close to the side wall of the guide rod 3 to avoid the binding line 4 being entangled on the vegetable leaves; because the guide ring 32 and the guide rotary head 33 are both freely rotating parts, therefore, under the traction of the binding line 4, no matter how the guide rod 3 rotates along the central axis of the rotating disk 2, the binding line 4 is arranged in the direction of the guide rod 3 facing the wire reel 15, to avoid the situation where the binding line 4 is entangled on the guide rod 3 when the guide rod 3 rotates.

[0032] When this embodiment is actually used, first open the wire trough cover 11 and put the wire reel 15 wrapped with the binding wire 4 into the wire trough, and fix the wire reel 15 to the hand crank 14 through the card slot structure; then pull out the binding wire 4 from the inner channel of the rotating table 1, pass through the anti-friction shaft gap of the guide ring 32, and then pass downward through the anti-friction shaft gap of the guide turntable 33; after the binding wire 4 is set, pull out its end and fix it to one end of the field ridge to be tied with a wooden stake, and then start the vegetable tying operation; move the device to the top of the vegetables to be tied, so that the rotating disk 2 is roughly coaxial with the vegetables, and then step on the pedal 17 to make the fixing cone penetrate into the ground to fix the device.

[0033] When starting the binding operation, first press the guide rod 3 to make the guide turntable 33 drop to the lowest point, and pull the guide rod 3 outward to move the guide turntable 33 to the outermost position; during the movement of the device, the position of the guide rod 3 can be fixed by pulling the guide rod 3 into the L-shaped short side groove of the sliding track 21; push the device to the vegetables to be bound, so that the rotating disk 2 is directly above the vegetables; for easy observation, the rotating disk 2 can be made of transparent material to facilitate visual positioning of the device.

[0034] After the device moves to its position, the guide rod 3 is kept pressed down and the guide rod 3 is rotated along the rotating disk 2 for a suitable number of circles. Since the end of the tying wire 4 is fixed, when the guide rod 3 rotates, the tying wire 4 moves with the guide rotating head 33 at the end of the guide rod 3. When the tying wire 4 contacts the vegetables, it will be wound around them. As the guide rod 3 continues to rotate, the tying wire 4 will be continuously drawn out from the wire drum 15 and tied to the vegetables. Figure 5 shown.

[0035] After turning several times to meet the binding requirements, just let go of the guide rod 3, and the guide rod 3 will slide inward under the action of the horizontal elastic connecting rod 51 in the elastic connector 5 to gather the scattered vegetable leaves; and at the same time, under the action of the vertical elastic connecting member 53, the binding line 4 is lifted to a suitable height to gather the vegetable leaves; then turn the hand crank 14 to make the wire drum 15 rotate in the opposite direction to tighten the binding line 4, such as Figure 6 As shown, the tying of the vegetables is completed, and the device can be pushed to the next vegetable to continue the tying operation.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that in this embodiment, a hand crank 14 is not used to connect the wire drum 15, but a winding motor is arranged on one side of the rotating table 1, and the output shaft of the winding motor is connected to the rotating shaft of the wire drum 15; the winding motor can be controlled to work by a button. In the last step of the binding process, only the button needs to be pressed to retract the binding wire 4 and tighten it without manual rotation, which can also save space and is more convenient to use.

[0038] Example 3

[0039] The difference between this embodiment and embodiment 2 is that an automatic wire winding and recovery system is used in this embodiment, including a wire winding motor, and a sensing system is arranged in cooperation with the wire winding motor; the sensing system monitors the tension applied to the binding wire 4 through sensors, and when the tension applied to the binding wire 4 is greater than a certain level, the sensing system will turn off the wire winding motor, so as to facilitate the movement of the device in the field or the tying of vegetables; when the sensor detects that the tension applied to the binding wire 4 is less than a certain level, the sensing system will determine that the binding wire 4 is in a state that needs to be tightened, and send a control signal to the wire winding motor, turning on the wire winding motor to automatically retract the binding wire 4, so that the binding wire 4 is tightened to tie the vegetables; in this embodiment, the binding wire 4 can be automatically tightened without manual operation, and the operation is more convenient. At the same time, since an automatic wire winding and recovery system that is controlled according to the force applied to the binding wire 4 is provided, the vegetables will not be damaged due to excessive tension of the automatic wire winding.
