[0002] One way of strawberry cultivation is potted cultivation. The advantages of potted cultivation are as follows: Potted strawberries are easy to manage, and compared with field strawberry cultivation, the resources consumed by single-plant strawberries are less. Some people regard potted strawberries as household ornamental and edible plants. However, large-scale agricultural potted strawberries can change the growth environment of strawberries to avoid the influence of cold currents and other airflows on strawberry growth, and at the same time avoid the influence on workers in all-weather greenhouse strawberry cultivation. Except for some potted strawberries supplied for household procurement and picking in farmhouses, the remaining strawberries need to be picked to meet market demand, so as to obtain strawberry cultivation profits.

[0040] One way of strawberry cultivation is potted cultivation. The advantages of potted cultivation are as follows: Potted strawberries are easy to manage, and compared with field strawberry cultivation, the resources consumed by single-plant strawberries are less. Some people regard potted strawberries as household ornamental and edible plants. However, large-scale agricultural potted strawberries can change the growth environment of strawberries to avoid the impact of cold currents and other airflows on strawberry growth, and at the same time avoid the impact on laborers in all-weather greenhouse strawberry cultivation. Except for some potted strawberries supplied for household procurement and picking in farmhouses, the remaining strawberries need to be picked to meet market demand, so as to obtain the profit of strawberry cultivation.

[0041] At present, potted strawberries are generally automatically picked by picking equipment. However, in the existing picking equipment, the transportation device uses a horizontally extending conveyor belt to sequentially transport multiple potted strawberries. Each potted strawberry is transported to the picking station and then picked by the picking device to achieve automatic picking of potted strawberries. However, the horizontally extending conveyor belt requires a large floor area and has certain requirements for the use space of the picking equipment.

[0042] In view of this, the present utility model provides a vertical strawberry transportation device 100 for transporting multiple strawberry planting pots 2000 in a strawberry picking equipment 1000. Figure 1 and Figure 2 This is an embodiment of the vertical strawberry transportation device 100 provided by the present utility model.

[0043] Please refer to Figure 1 and Figure 2 As shown, the vertical strawberry transportation device 100 includes a frame 1, two sprocket drive mechanisms 2, and multiple carrier frames 3. The frame 1 is arranged to extend in the vertical direction; the two sprocket drive mechanisms 2 are arranged on the frame 1 and are spaced apart in a first direction. Each sprocket drive mechanism 2 includes a driving wheel 21, a driven wheel 22, and a chain 23. The driving wheel 21 and the driven wheel 22 are spaced apart in the vertical direction and can rotate relative to the frame 1 around an axis extending in the first direction. The chain 23 is sleeved on the outer circumferences of the driving wheel 21 and the driven wheel 22 to rotate relative to the frame 1 under the drive of the driving wheel 21; multiple carrier frames 3 are rotatably arranged on the chain 23 and are spaced apart in the circumferential direction of the chain 23. At least one strawberry planting pot 2000 is placed on each carrier frame 3; wherein, the first direction is vertically arranged in the horizontal plane with respect to the vertical direction.

[0044] In the technical solution of the present utility model, the frame 1 is arranged to extend in the vertical direction, the driving wheel 21 and the driven wheel 22 are spaced apart in the vertical direction, and the chain 23 is driven to rotate, so that the chain 23 drives multiple carrier frames 3 to rotate cyclically in the vertical direction, thereby realizing the transportation of multiple strawberry planting pots 2000; compared with the existing transportation device, the vertical strawberry transportation device 100 provided by the present utility model greatly reduces the floor area, reduces the requirement for the use space, expands the applicable range, and improves the transportation efficiency.

[0045] Further, please refer to Figure 1 and Figure 2, each of the sprocket drive mechanisms 2 further includes a plurality of connecting plates 24. The plurality of connecting plates 24 are spaced apart on the chain 23 and are rotatably connected to the plurality of carrier frames 3 one by one. When the connecting plates 24 rotate with the chain 23, the carrier frames 3 can rotate under the action of gravity to be parallel to the frame 1. In this way, during the rotation of the chain 23, each of the carrier frames 3 is always parallel to the frame 1, thereby ensuring the stability of the strawberry planting pots 2000 placed on the carrier frames 3 and preventing the strawberry planting pots 2000 from falling off the carrier frames 3.

[0046] More specifically, please refer to Figure 1 , in an embodiment of the present invention, the connecting plate 24 is trapezoidally arranged and is threadedly connected to the chain 23.

One of the two ends of each transmission shaft 25 is inserted into a connecting plate 24 of one sprocket drive mechanism 2, and the other is inserted into a connecting plate 24 of the other sprocket drive mechanism 2. In this way, the carrier frame 3 is rotatably connected to the connecting plate 24 through the transmission shaft 25, so that the carrier frame 3 can rotate relative to the transmission shaft 25 under the action of gravity; at the same time, the two sprocket drive mechanisms 2 are connected through the transmission shaft 25, improving the movement stability of the carrier frame 3.

[0048] Further, please refer to Figure 1 and Figure 2 , each of the transmission shafts 25 is limited by at least two nuts 26; in this way, the transmission shaft 25 is prevented from shifting and disengaging from the connecting plate 24, ensuring the movement stability of the carrier frame 3.

In this way, the structure is compact, and the occupied space of the vertical strawberry transportation device 100 can be further reduced.

[0054] Further, please refer to Figure 1 and Figure 2 , the frame 1 further includes a second support assembly 13, including two second support frames 131 spaced apart along the first direction. The two second support frames 131 are respectively arranged at the lower ends of the two first support frames 111. In this way, through the arrangement of the second support frames 131, a space below one of the driving wheel 21 and the driven wheel 22 located below can accommodate a load-bearing rack 3, avoiding interference between the load-bearing rack 3 rotating to below the chain 23 and the ground during the rotation of the chain 23, which affects the cyclic transportation.

[0055] More specifically, please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the driven wheel 22 and the driving wheel 21 are spaced apart at intervals in the vertical direction.
