Description

Technical Field

[0001] This invention belongs to the field of vertical planting technology, specifically relating to an automatic spraying device for vertical planting. Background Technology

[0002] Multi-layer vertical farming technology is a technical system that, based on vertical farming, utilizes multi-layer structures (such as trellises, troughs, and hanging structures) to fully utilize vertical space and achieve multi-dimensional, multi-level crop cultivation. It maximizes the use of resources such as light, temperature, and air, and is particularly suitable for facility agriculture (greenhouses, sheds) or scenarios with limited space. To ensure the healthy growth of vertically grown plants, a scientifically designed automatic spraying device is needed to spray water, nutrient solutions, etc.

[0003] Chinese patent CN222982184U discloses a water storage structure and planting tower for a three-dimensional planting tower. This invention uses a rotating component that simultaneously rotates the planting tower body and the spraying component inside the tower. The different rotation speeds of the planting tower body and the spraying component allow the spraying component to more evenly spray nutrient solution onto the plants inside the planting tower, resulting in better spraying effect and higher nutrient solution utilization. However, because the planting pots are tilted downwards and inwards towards the planting tower body, and the spraying component is located inside the tower body, the sprayed nutrient solution does not easily penetrate the soil and may even erode the potting soil, leading to poor spraying effect and difficulty in observing and controlling the spraying angle.

[0004] Chinese patent CN108718802B discloses a three-dimensional vegetable planting device and its planting method. A water pump sprays water from the top of the device, which then leaks downwards through drainage holes at the bottom of each layer to ensure each layer absorbs water. This operation inevitably leads to uneven liquid spraying; the upper layers may be over-sprayed while the lower layers are under-sprayed. Furthermore, to ensure sufficient water absorption in the lower layers, the soil in the upper layers may become excessively waterlogged, causing the plant roots and stems to rot and die.

[0005] To address the problem that existing spraying structures cannot adequately guarantee the spray volume of each layer and control the spraying angle to achieve the best spraying effect, it is necessary to improve the structure of the automatic spraying device to solve the current technical problems.

[0011] To better realize the present invention, the guide tube is fixedly connected to the mounting head.

[0012] To better realize the present invention, the guide rail is integrally formed into a ring structure by two linear guide rails parallel to the guide rod and two semi-circular guide rails.

[0017] Beneficial effects: This invention uses a drive motor to move a slider along a guide rail, causing the guide tube to make a circular or linear reciprocating motion, which in turn drives multiple nozzles to achieve automatic watering of multi-layered plants in a three-dimensional planting system. This is time-saving, labor-saving, efficient, and convenient. The nozzles can also be rotated to adjust their orientation for more accurate watering. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figure 1 - Figure 4 As shown, an automatic spraying device for vertical planting includes a support frame 1, which is a horizontally placed triangular prism structure. A guide rail 2 is fixedly connected to the bottom of the support frame 1. The cross section of the guide rail 2 is a T-shaped structure, including a first vertical plate 21 and a first horizontal plate 22 fixedly connected to the middle of the first vertical plate 21.

[0022] The guide rail 2 is movably connected to the slider 3, which has a U-shaped structure and includes two second horizontal plates 32 and a second vertical plate 31 fixedly connected between the two second horizontal plates 32.

[0023] A first rotating shaft 33 is rotatably provided between the two second horizontal plates 32, away from the first horizontal plate 22. The first rotating shaft 33 is fixedly connected to a drive wheel 34, which rolls against the surface of the first vertical plate 21. The top end of the first rotating shaft 33 passes through the second horizontal plate 32 and is connected to a drive motor 35.

[0024] Two second horizontal plates 32 are symmetrically provided with two second rotating shafts 36 near the first horizontal plate 22. Both second rotating shafts 36 are fixedly connected with driven wheels 37, which roll against the surface of the first vertical plate 21.

[0025] The slider 3 is fixedly connected to the guide tube 4, and the guide tube 4 is connected to the mounting head 5 away from the slider 3. The top of the support frame 1 is fixedly provided with a guide rod 8, which is located directly above the support frame 1 and extends in a direction parallel to the extension direction of the support frame 1. The mounting head 5 is slidably connected to the guide rod 8.

[0026] The guide rail 2 includes two linear guide rails 23 parallel to the guide rod 8. The two linear guide rails 23 are symmetrically fixed on both sides of the support frame 1. Correspondingly, two sets of structures such as the guide pipe 4, nozzle 6, and slider 3 are symmetrically arranged, which are for watering and fertilizing the plants on both sides of the support frame 1. The two guide pipes 4 are symmetrically fixed and connected to the mounting head 5.

[0027] The guide pipe 4 is adjustablely connected to multiple nozzles 6. Multiple threaded connecting pipes 41 are spaced apart on the guide pipe 4, each threaded connecting pipe 41 having a sealing insert 42. Each nozzle 6 has a threaded sleeve 61 adapted to the threaded connecting pipe 41, and the threaded sleeve 61 contains an elastic sealing sleeve 62 adapted to the sealing insert 42. The guide pipe 4 is connected to a water supply pipe 7 located near the mounting head 5.

[0028] The working principle of this embodiment can be summarized as follows: The drive motor 35 is started, which drives the drive wheel 34 to rotate. Under the friction between the drive wheel 34 and the first vertical plate 21 and the limiting action of the driven wheel 37, the slider 3 moves along the linear guide rail 23. By controlling the forward and reverse rotation of the motor, the slider 3 reciprocates. During the reciprocating motion of the slider 3, the guide pipe 4 and the mounting head 5 move reciprocally along the guide rod 8, which passes water through the water supply pipe 7. The water enters the nozzle 6 through the water supply pipe 7, the guide pipe 4, the threaded connecting pipe 41, and the sealing insert 42, and is sprayed onto the plants cultivated on the support frame 1. The motor can drive multiple nozzles 6 to achieve automatic watering of multi-layered plants in a three-dimensional planting system, which is time-saving, labor-saving, efficient and convenient. The orientation of the nozzle 6 can be adjusted by rotating it for more accurate watering.

[0029] Example 2 like Figure 5 - Figure 6 As shown, an automatic spraying device for vertical planting differs from Embodiment 1 in that: the guide rail 2 is integrally formed into a ring structure by two linear guide rails 24 parallel to the guide rod 8 and two semi-circular guide rails 25. The guide pipe 4 is rotatably connected to the mounting head 5. Correspondingly, a set of structures such as the guide pipe 4 and the slider 3 is arranged to rotate around the support frame 1 for circulating watering and fertilization.

[0030] The working principle of this embodiment can be summarized as follows: Start the drive motor 35, which drives the drive wheel 34 to rotate. Under the friction between the drive wheel 34 and the first vertical plate 21 and the limiting action of the driven wheel 37, the slider 3 moves cyclically along the annular guide rail 2. During the movement, the slider 3 drives the guide pipe 4 to move cyclically as well. The mounting head 5 first moves in a straight line. When the mounting head 5 moves to one end of the guide rod 8, the slider 3 moves in a circular motion around the semi-circular guide rail 25. At this time, the mounting head 5 stops moving in a straight line and temporarily stops moving. The guide pipe 4, driven by the slider 3, moves in a circular motion around the mounting head 5 until it moves to the other side of the linear guide rail 24, which opens the water supply pipe 7. The water enters the nozzle 6 through the water supply pipe 7, the guide pipe 4, the threaded connecting pipe 41, and the sealing insert 42, and is sprayed onto the plants cultivated on the support frame 1 through the nozzle 6. The motor can drive multiple nozzles 6 to automatically water multi-layered plants in a three-dimensional planting system, saving time and effort, and is highly efficient and convenient. The direction of the nozzles 6 can be adjusted by rotating them for more accurate watering.

[0031] Example 3 like Figure 7 As shown, an automatic spraying device for vertical planting differs from Embodiment 1 in that: the support frame 1 is a conical structure, the guide rail 2 is a circular guide rail 26 fixed to the bottom of the support frame 1, the mounting head 5 is rotatably connected to the top of the support frame 1, and the guide pipe 4 is fixedly connected to the mounting head 5. Accordingly, a set of structures such as the guide pipe 4 and the slider 3 are arranged to rotate around the support frame 1 for circulating watering and fertilization.

[0032] The working principle of this embodiment can be summarized as follows: The drive motor 35 is started, which drives the drive wheel 34 to rotate. Under the friction between the drive wheel 34 and the first vertical plate 21 and the limiting action of the driven wheel 37, the slider 3 moves cyclically along the circular guide rail 26. During the movement of the slider 3, the guide pipe 4 moves cyclically along with it. Driven by the slider 3, the guide pipe 4 moves in a circular motion around the top of the mounting frame, driving the mounting head 5 to move in a circular motion, thus passing water through the water supply pipe 7. The water flows sequentially through the water supply pipe 7, the guide pipe 4, the threaded connecting pipe 41, and the sealing insert 42 into the nozzle 6, and is sprayed onto the plants cultivated on the support frame 1 through the nozzle 6. The motor drive can drive multiple nozzles 6 to achieve automatic watering of multi-layered plants in three-dimensional planting, saving time and effort, and is highly efficient and convenient. The orientation of the nozzle 6 can be adjusted by rotating it for more accurate watering.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
