Description

Technical Field

[0001] This utility model relates to the field of greenhouse three-dimensional cultivation technology, and in particular to a greenhouse three-dimensional cultivation device. Background Technology

[0002] Vertical farming systems are agricultural facilities that utilize a multi-layered, rack-like structure within a greenhouse to achieve vertical planting. By constructing multiple planting racks, they make full use of the vertical dimension of space, allowing more crops to be grown within a limited area. They are commonly used for cultivating vegetables, flowers, and fruits.

[0003] When growing watermelons, cantaloupes, and other melons in greenhouses, trellises are typically erected to allow the plants to climb upwards, maximizing yield and increasing seed density within the limited space. This also prevents the melons from coming into contact with soil, which can negatively impact their taste. However, most existing trellises are not easily adjustable in height. If the vines grow too long, the fruit may be too high off the ground, making later management and harvesting difficult. Furthermore, to prevent the fruits from becoming too heavy, netting is often added to the trellises for support. Once ripe, this netting is difficult to remove, further complicating harvesting.

[0004] Therefore, it is necessary to provide a new greenhouse vertical cultivation device to solve the above-mentioned technical problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5A greenhouse vertical cultivation device includes: a base 1 with symmetrically fixed columns 2 to ensure no shaking or displacement during subsequent use; a threaded rod 3 rotatably connected to the top of the fixed column 2 to ensure smooth rotation; a drive assembly installed on the inner wall of the base 1, wherein the bottom end of the threaded rod 3 is fixedly connected to the inner wall of the first bevel gear 4 by a key connection to ensure stable power transmission; a second bevel gear 5 rotatably connected to the left inner wall of the base 1, the first bevel gear 4 and the second bevel gear 5 being meshed for efficient power transmission; and a motor fixedly connected to the top left side of the base 1. 6. The external drive end of the motor 6 is fixedly connected to the inner wall of the second bevel gear 5 by means of a coupling to ensure the accuracy of power transmission. The bottom end of the threaded rod 3 is fixedly connected to a rotating wheel 7. The external part of the rotating wheel 7 is rotatably connected to the inside of the base 1. The two rotating wheels 7 are fitted with pulleys 8. The pulleys 8 can realize the synchronous rotation between the two rotating wheels 7. Two sliding holes 9 are opened on the adjacent side of the two fixed columns 2. Multiple concave sliding blocks 10 are slidably connected to the outside of the fixed columns 2. A first crossbar 11 is fixedly connected to the adjacent side of every two concave sliding blocks 10. The first crossbar 11 can bear the weight of the vines and fruits.

[0027] The external threaded connection of the fixed column 2 has multiple threaded rings 12 to ensure stability during movement. The external fixed connection of the threaded rings 12 is a limit ring 13, which limits the axial movement range of the threaded rings 12 on the fixed column 2. The external rotatable connection of the limit ring 13 is a connecting ring 14. The external of the threaded ring 12 is rotatably connected to the inner ring of the connecting ring 14 to ensure smooth relative rotation between the two. Two connecting blocks 15 are fixedly connected to one side of the connecting ring 14. The external of the connecting block 15 is slidably connected to the inner wall of the sliding hole 9 to ensure that there is no jamming during movement.

[0028] A locking assembly is installed on the front side of the concave sliding block 10 to fix the position of the concave sliding block 10 on the fixing post 2. The locking assembly includes a C-shaped connecting block 16. The rear side of the C-shaped connecting block 16 is fixedly connected to the front side of the concave sliding block 10. A bolt 17 is threadedly connected to the inner wall of the C-shaped connecting block 16. A friction block 18 is rotatably connected to one end of the bolt 17. The side of the friction block 18 away from the bolt 17 is in close contact with the outside of the concave sliding block 10, and the concave sliding block 10 is firmly fixed to the fixing post 2 by friction. When unlocking, the side of the friction block 18 near the bolt 17 contacts the side of the C-shaped connecting block 16 near the concave sliding block 10 to realize the unlocking operation. A turning disc 19 is fixedly connected to the other end of the bolt 17. The surface of the turning disc 19 is designed with anti-slip texture to facilitate manual rotation by the operator.

[0029] A second crossbar 20 is fixedly connected to the top outer wall of the base 1. Multiple locking blocks 21 are inserted into the outside of the second crossbar 20, and these locking blocks 21 also match the first crossbar 11. The fit between the locking blocks 21 and the second crossbar 20 ensures that there will be no loosening during use. A support plate 22 is fixedly connected to the top of every two locking blocks 21. The bottom end of the support plate 22 is in close contact with the top of the second crossbar 20. A net bag 23 is provided at the top of the support plate 22. When the net bag 23 is placed over the fruit, its expansion force can be used to support the fruit. The net bag 23 is attached to the first crossbar 11 by a rope. The bottom of the net bag 23 can contact the support plate 22 to provide additional support and prevent the net bag 23 from being subjected to excessive force, which would affect the normal growth of the melons and fruits. The top of the net bag 23 is equipped with two sets of zippers 24. The top of the net bag 23 has a vine hole 25 on the side close to the two sets of zippers 24. The net bag 23 is lined with a fruit protective sleeve made of foam plastic. When placing small fruits, they are placed in the protective sleeve. The fruit protective sleeve is made of soft and cushioning foam plastic, which can effectively protect the fruits from damage.

[0030] The working principle of the greenhouse three-dimensional cultivation device provided by this utility model is as follows:

[0031] When motor 6 is turned on, it transmits power to the second bevel gear 5 through the motor shaft. The second bevel gear 5 rotates with the rotation of the motor shaft. Since the first bevel gear 4 and the second bevel gear 5 mesh with each other, the rotation of the second bevel gear 5 drives the first bevel gear 4 to rotate. The first bevel gear 4 is fixedly connected to the threaded rod 3, thereby causing the threaded rod 3 to start rotating. When the threaded rod 3 rotates, the threaded ring 12, which is threaded to the threaded rod 3, will move along the axial direction of the threaded rod 3 due to the transmission action of the thread. During the movement, the threaded ring 12 drives the connecting ring 14 to move through the limiting ring 13. The connecting ring 14 is connected to the concave sliding block 10 through the connecting block 15, thereby causing the concave sliding block 10 to slide in the sliding hole 9 of the fixed column 2. According to the initial growth height of the vine, the operator adjusts the position of the first horizontal bar 11 by controlling the running time and direction of motor 6.

[0032] Once the first crossbar 11 reaches the appropriate height, a fixing operation is performed by rotating the turning disc 19, which is fixedly connected to the bolt 17. As the turning disc 19 rotates, the bolt 17 rotates and advances in the inner thread of the C-shaped connecting block 16. One end of the bolt 17 is rotatably connected to the friction block 18. During the advance of the bolt 17, it pushes the friction block 18 towards the concave sliding block 10. When the friction block 18 and the concave sliding block 10 are in close contact, the friction force is used to fix the concave sliding block 10 to the fixing post 2, thereby fixing the position of the first crossbar 11. After fixing, when the threaded rod 3 rotates again, it will not cause the fixed first crossbar 11 to move. This is because only the fixed first crossbar 11 is locked, while the threaded ring 12 and the connecting ring 14 are rotatably connected, so the threaded ring 12 can still move and is not locked by the threaded rod 3.

[0033] Vines are secured: The vines are secured to the first horizontal bar 11 at regular intervals to guide the vines to grow in an orderly manner along the direction of the first horizontal bar 11.

[0034] mid-growth

[0035] Fruit support preparation: When the vine grows and the first row of melons grows below, the fruit needs to be supported. First, observe the position and growth of the fruit to determine the installation position of the support plate 22. Adjust the locking block 21 on the second horizontal bar 20 as needed so that the locking block 21 can accurately correspond to the position of the fruit. When the bottom fruit is ripe and removed, the locking block 21 can be removed and installed on the first horizontal bar 11. The locking block 21 and the first horizontal bar 11 also match.

[0036] Fruit Placement in Net Bag: Install the support plate 22 onto the locking block 21, ensuring a secure connection. Then, lift the fruit from the vine and slowly place it into the net bag 23. The foam plastic fruit protective sleeve lining the net bag 23 provides cushioning and protection, preventing direct collision between the fruit and the net bag during placement and thus avoiding damage to the skin. The net bag 23 then contacts the support plate 22, providing additional support. The top of the net bag 23 is then tied to the nearest first horizontal bar 11 using a rope. When the fruit is small, the tension of the rope provides support to the net bag 23, stabilizing its position. As the fruit continues to grow, the bottom of the net bag 23 contacts the support plate 22, providing additional support, reducing stress on the net bag 23, and ensuring normal fruit growth.

[0037] Management and harvesting stages

[0038] Preparation for adjusting the position of the crossbar: When the fruits below have been harvested and the fruits above have grown to a high position, it is necessary to move the fruit position down for easier management later. First, operate the locking component on the concave sliding block 10 whose position needs to be adjusted. Rotate the turning plate 19 so that the turning plate 19 drives the bolt 17 to rotate in the opposite direction. During the rotation, the bolt 17 drives the friction block 18 to move away from the concave sliding block 10 until the friction block 18 separates from the concave sliding block 10, thus releasing the fixation of the concave sliding block 10.

[0039] Adjusting the position of the crossbar: Turn on the motor 6, so that the motor 6 drives the threaded rod 3 to rotate in the opposite direction. The reverse rotation of the threaded rod 3 causes the threaded ring 12 to move downward along the threaded rod 3. Through the connecting ring 14 and the connecting block 15, the concave sliding block 10 slides downward in the sliding hole 9 of the fixed column 2, thereby causing the first crossbar 11 to move downward. In order from top to bottom, the position of each crossbar is adjusted in turn, and the resulting position is gradually moved downward.

[0040] Fruit picking: When picking fruits, first open the zipper 24 at the top of the net bag 23. Ensure that the zipper 24 is pulled smoothly to avoid jamming and damaging the net bag. After opening the zipper 24, carefully take out the fruits through the vine hole 25. Since the net bag 23 is lined with a fruit protective sleeve, the fruits can be taken out together with the protective sleeve when taking out the fruits. There is no need to remove and install the protective sleeve separately, which is convenient and quick.
