[0002] At present, most of the planting of cut roses is small and medium-sized. With the continuous increase in the planting volume, the harvesting of cut roses has become a very worthy issue. When harvesting roses, the existing harvesting methods are as follows: 1. Manually embrace rose cut branches; 2. Put the rose cut branches on a cloth bag and slowly move them; 3. Put the picked rose cut branches on a picking car equipped with tracks.

[0039] After the second end of the traction rope 84 passes through the upper end of the compression spring 87, it passes through a plurality of pulleys 85 and is finally fixedly connected to the winding wheel 86. By tightening and releasing the traction rope 84 through the winding wheel 86, the third connecting rod 88 can drive the fourth connecting rod 811 to be lifted upward by the contraction force of the compression spring 87, thereby driving the two supporting legs 8 to be lifted upward synchronously. The tension of the compression spring 87 can also be used to limit the rotation of the rotating bearing 81 when the fourth connecting rod 811 falls, so that the fourth connecting rod 811 remains in a horizontal state.

[0040] The walking assembly is connected to the frame. In a preferred embodiment of the utility model, the walking assembly includes a walking wheel 7 and a walking wheel fixing frame 71. The walking wheel 7 is connected to the walking wheel fixing frame 71 by fixing bolts 72, and the walking wheel fixing frame 71 is fixedly connected to the fixing plate. The walking wheel 7 of the utility model is a universal wheel, the diameter of the walking wheel is greater than 80 cm and the width is less than 5 cm. By setting a walking wheel with a large diameter and narrow width, it can save effort and walk flexibly in the flowers, which is convenient for transportation.

[0041] The specific implementation of the utility model is further described below:

[0042] like Figure 1-5As shown, a cut branch flower harvesting vehicle of the utility model is provided with two sets of inverted isosceles frames and are symmetrically arranged, both ends of the push handle 1 are connected to the fixed rods of the telescopic rod 5, and the movable rod of the telescopic rod 5 is fixedly connected to the diagonal support 42 at the first end of the frame. The first cross bar 46, the first vertical rod 44 and the second vertical rod 45 are provided on both sets of frames to play a restraining role on the storage bag 3 containing the cut branches of flowers, so as to prevent the storage bag 3 from shaking left and right during the movement of the vehicle.

[0043] The storage bag 3 is detachable. When in use, the upper edges of both sides of the storage bag 3 are connected to the two top cross braces 41 of the frame through the hanging ears 411 and the hanging holes, which is convenient for disassembly and replacement.

[0044] The bundling net is detachable and is connected by three longitudinal bundling straps 2 and two transverse bundling straps 2. When in use, the hook on the first side of the bundling net is hung on the buckle hole on the first side of the storage bag 3, and the second end of the bundling net is passed over the top of the frame and hung on the buckle hole on the second side of the storage bag 3, and the cut flowers are bundled therein to prevent them from falling out of the vehicle during the movement of the vehicle. When not in use, the bundling net is placed inside the storage bag 3 and hung on the buckle hole of the storage bag 3 from the inside to prevent loss. In the utility model, the bundling straps 2 are connected using wide bundling straps, and the width of each bundling strap is preferably greater than 3 cm, which can better protect the original appearance of the cut flowers and prevent them from being strangled.

[0045] The telescopic rod 5 is connected to the push handle 1, and its movable rod can be extended and retracted up and down inside the fixed rod. The push handle 1 can have a certain telescopic space to achieve raising or lowering the height of the push handle 1 to adapt to users of different heights.

[0046] A third cross bar may be provided between the first end and the second end of the top cross brace 41 of the two symmetrically arranged vehicle frames, and a second cross bar may be provided between the first end and the second end of the first cross bar 46 of the two symmetrically arranged vehicle frames, so as to strengthen the stability of the vehicle frames. The two vehicle frames are connected as a whole by the second cross bar, the third cross bar and the first connecting rod 6. The fixing plate 61 is connected as a whole with the first connecting rod 6 and the second connecting rod 62, and the running wheel 7 is fixedly connected with the fixing plate 61 by welding through the running wheel fixing frame 71.

[0047] The support foot 8 is connected to the fourth connecting rod 811 through a sleeve bearing 82. The setting of the sleeve bearing 82 can ensure that the support foot 8 can only tilt forward after being folded to avoid hitting the foot. When the vehicle stops and the support foot is put down, if the vehicle moves slightly forward, the support foot can ensure that it stands vertically on the ground to stabilize the vehicle.

[0048] The fourth connecting rod 811 is rotatably connected to the bottom cross brace via a rotating bearing 81 , so that the supporting leg 8 can be retracted and extended under the drive of the fourth connecting rod 811 .

[0049] The first end of the traction rope 84 is fixed on the fourth connecting rod 811, and a compression spring 87 is arranged between the fourth connecting rod 811 and the third connecting rod 88. The second end of the traction rope 84 first passes through the compression spring 87, then passes around a plurality of pulleys 85 in sequence, and then is wound around a winding wheel 86 arranged on the telescopic rod 5. The traction rope 84 is contracted and extended by the rotation of the winding wheel 86.

[0050] In specific operation, when the vehicle is moving, the winding wheel 86 is rotated to the right, which drives the traction rope 84 to contract synchronously, drives the compression spring 87 to contract, and under the drive of the third connecting rod 88, the two supporting feet 8 are synchronously retracted upward, and the rotating handle of the winding wheel 86 is locked. When parking, the winding wheel 86 is rotated to the left, and the traction rope 84 is synchronously loosened. The tension of the compression spring 87 supports the fourth connecting rod 811 and the third connecting rod 88, so that the rotation of the rotating bearing 81 is synchronously limited. At this time, the supporting foot 8 is unfolded and perpendicular to the ground, and the supporting foot is stably standing on the ground through the sleeve bearing 82, and the rotating handle of the winding wheel 86 is synchronously locked. The supporting foot 8 and the running wheel 7 support the vehicle body together, which can make the vehicle more stable and convenient for harvesting flowers.
