[0035] The support frame 5 is rotatably disposed in the harvesting chamber 30. The rotating end of the support frame 5 is located at the outlet 2. The support frame 5 has a cutting space 31. A first winding box 6 is provided at the end of the support frame 5 near the outlet 2. The winding of the first winding box 6 is connected to a cutter 7. The cutter can slide along the cutting space 31 so that the winding of the first winding box 6 can cover the cutting space 31.

[0036] The second take-up box 8 is mounted on the support frame 5 and located at the end of the cutting space 31 away from the outlet 2. The roll of the second take-up box 8 is connected to the cutter 7. The roll of the second take-up box 8 is connected to the take-up operation mechanism through the transmission mechanism. The take-up operation mechanism is connected to the lifting operation mechanism, which is located at the end of the long support rod 3 away from the harvester box.

[0037] By holding the handle 4, the harvesting box 1 is placed over the milkvetch, placing the milkvetch inside the harvesting chamber 30 and the tender shoots above the cutting space 31. By operating the winding mechanism at the end of the long support rod 3, the cutter 7 slides, thereby cutting the stems of the milkvetch tender shoots located in the cutting space 31. At the same time, the winding tape of the first winding box 6 unfolds to catch the cut milkvetch tender shoots. Then, the harvesting box 1 is lifted so that the discharge port 2 is located outside the collection basket or other storage device. Then, the lifting mechanism is operated to rotate and tilt the support frame 5 around one end of the discharge port 2, discharging the milkvetch tender shoots on the winding tape of the first winding box 6 from the harvesting box 1, completing the harvesting of the milkvetch tender shoots. This method is suitable for standing harvesting, reducing frequent bending or squatting operations, alleviating back strain, and avoiding problems such as nail wear and skin scratches when harvesting by hand. It is especially protective for workers who work long hours, allowing for quick harvesting, convenient operation, and effectively improving harvesting efficiency.

[0038] In one embodiment of this utility model, the lifting mechanism includes:

[0039] A sliding groove 9 is formed on the side wall of the long support rod 3;

[0040] The slider 10 is slidably fitted in the sliding groove 9. A connecting plate 11 is fixedly connected to the slider 10, and a winding operation mechanism is provided on the connecting plate 11.

[0041] By pulling the connecting plate 11, the slider 10 slides along the sliding groove 9, which drives the winding operation mechanism to slide synchronously, thereby causing the entire support frame 5 to rotate and tilt.

[0042] In one embodiment of this utility model, the winding operation mechanism includes:

[0043] The rotating rod 12 is rotatably mounted on the connecting plate 11. The rotating rod 12 has a spiral groove 13 and is connected to the transmission mechanism.

[0044] The sliding ring 14 is slidably sleeved on the rotating rod 12. A mating block is fixedly connected to the sliding ring 14, and the mating block is slidably engaged with the spiral groove 13.

[0045] The transmission mechanism includes a pair of transmission wheels 20 and a transmission chain 21 connected to the pair of transmission wheels 20. The pair of transmission wheels 20 are fixedly connected to the rotating rod 12 and the reel of the second winding box 8, respectively.

[0046] By pulling the sliding ring 14, the mating block on the sliding ring 14 slides along the spiral groove 13. The transmission effect between the mating block and the spiral groove 13 causes the rotating rod 12 to rotate, which in turn drives the shaft of the second winding box 8 to rotate through the transmission wheel 20 and the transmission chain 21, thereby winding up the tape of the second winding box 8. The tape of the second winding box 8 pulls the cutter 7 to slide, so that the cutter 7 cuts the tender shoots of milkvetch. At the same time, the tape of the first winding box 6 gradually unfolds to cover the cutting space 31. The tape of the first winding box 6 is kept in the unfolded state until the inclined support frame 5 is lifted. After the tender shoots of milkvetch are discharged through the discharge port 2, the support frame 5 returns to its initial state.

[0047] In one embodiment of this utility model, a first guide rod 15 is fixedly connected in the sliding groove 9. The first guide rod 15 passes through the slider 10 and slides with the slider 10. A first spring 16 is sleeved on the first guide rod 15 and fixedly connected between the end of the sliding groove 9 and the slider 10.

[0048] The first guide rod 15 and the first spring 16 can both improve the sliding stability of the slider 10 and enable the slider 10 to automatically reset.

[0049] In one embodiment of this utility model, a pull plate 17 is fixedly connected to the sliding ring 14, a second guide rod 18 is slidably passed through the pull plate 17, the second guide rod 18 is fixedly connected to the connecting plate 11, and a second spring 19 is sleeved on the second guide rod 18 and fixedly connected between the pull plate 17 and the connecting plate 11.

[0050] By pulling the pull plate 17, the sliding ring 14 is driven to slide along the rotating rod 12. The second guide rod 18 and the second spring 19 can improve the sliding stability of the pull plate 17, prevent the sliding ring 14 from rotating, and enable the pull plate 17 to automatically reset.

[0051] In one embodiment of this utility model, the side wall of the harvester box 1 is provided with a first through groove 22 and a second through groove 23 that are connected to each other. A first connecting block 24 is slidably fitted in the first through groove 22. The first connecting block 24 is fixedly connected to the cutter 7 and the tape of the first winding box 6. A second connecting block 25 is slidably fitted in the second through groove 23. The second connecting block 25 is fixedly connected to the end of the support frame 5 away from the outlet 2 and the side wall of the second winding box 8.

[0052] When the transmission chain 21 is in a tensioned state, the second connecting block 25 can be slid along the second through groove 23 by lifting the second take-up box 8, which can realize the flipping of the support frame 5. By winding the tape of the second take-up box 8, the first connecting block 24 can be pulled to slide along the first through groove 22, which drives the cutter 7 to slide synchronously.

[0053] Furthermore, in order to improve the reset effect and sliding stability of the support frame 5, a third spring can be fixedly connected between the end of the second through groove 23 and the second connecting block 25, and a third guide rod that passes through the second connecting block 25 and slides in cooperation with the second connecting block 25 can be fixedly connected in the second through groove 23.

[0054] In one embodiment of this utility model, the first winding box 6 is a self-resetting winding box. The self-resetting winding box usually has a built-in torsion spring, such as a seat belt structure, which can realize the automatic reset of the winding of the first winding box 6 and the reset of the cutter 7.

[0055] In one embodiment of the present invention, a negative pressure device 26 is provided on the harvesting box 1. The negative pressure device 26 is connected to a negative pressure suction port 27 located above the cutting space 31 in the harvesting chamber 30. The negative pressure device 26 is connected to a switch button 28, which is located on the handle 4.

[0056] By activating the switch button 28, the negative pressure device 26 and the negative pressure suction port 27 can keep the milkvetch in the harvesting chamber 30 upright, which facilitates accurate cutting of the milkvetch shoots and improves the harvesting effect. After the milkvetch shoots are cut, the negative pressure device 26 is turned off to prevent the milkvetch shoots from being sucked by the negative pressure suction port 27.

[0057] In one embodiment of this utility model, a lifting bracket 29 is fixedly connected to the bottom of the harvesting box 1. After the lifting bracket 29 contacts the bottom surface, the top of the milkvetch is located inside the harvesting box 1, which makes it convenient for the operator to observe the height position of the covered milkvetch through the gap of the lifting bracket 29.
