Description

Technical Field

[0001] This utility model relates to the field of agricultural cultivation equipment, and in particular to a device for tiered strawberry cultivation. Background Technology

[0002] Sunlight plays a crucial role in the growth cycle, fruit quality, and yield of strawberries. Strawberries require at least 8 hours of sunlight daily for normal growth and development, and 12-15 hours of long-day sunlight during the flowering and structural development stage to promote sugar accumulation and increase yield. Prolonged low light can lead to excessive vegetative growth, pale leaves, poor flower bud differentiation, poor fruit coloring, and reduced yield. However, continuous strong sunlight can inhibit growth, triggering a semi-dormant mechanism in strawberries, slowing plant growth, resulting in smaller fruits with reduced sweetness. Excessive direct sunlight can also cause sunscald on leaves, leading to drying and discoloration, resulting in sour and astringent fruits and insufficient sugar accumulation.

[0003] Elevated strawberry cultivation is an agricultural technique that uses cultivation racks to lift strawberry plants off the ground, offering advantages such as labor saving, increased land utilization, and optimized fruit quality. Elevated cultivation creates a vertically elevated growing environment for strawberries, changing the traditional squatting posture and reducing labor intensity, while also facilitating visitor picking experiences. However, because the strawberries in elevated cultivation hang outside the planting troughs, a problem arises: insufficient light between adjacent rows of strawberries, leading to poor fruit coloring, reduced sweetness, and lower yield. For example, in a multi-functional three-dimensional strawberry cultivation rack as described in patent CN213881034U, strawberries between adjacent planting boxes suffer from insufficient sunlight, affecting their shape, taste, and yield. Some elevated cultivation methods also install hanging ropes on the roof to suspend the planting boxes in the air; these hanging structures also affect the amount of light entering the greenhouse, further reducing the amount of sunlight the strawberries receive.

[0004] Patent CN 115777384 B discloses a multifunctional strawberry planting rack. This rack features a rotating planting box and a reflective film attached to the support frame to increase light exposure through the reflective film and the rotating frame. However, this structure is overly complex and costly to manufacture. Furthermore, the method of using half the area for natural light and supplementing with reflective film is unreasonable and impractical. Moreover, this equipment is difficult to implement for large-scale cultivation.

[0005] How to increase sunlight exposure while improving land utilization through elevated planting has become an urgent problem to be solved. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a device for tiered strawberry cultivation. This device improves land utilization while ensuring that all strawberries receive equal sunlight, reducing variability and increasing yield.

[0007] A device for tiered strawberry cultivation includes a horizontally arranged lead screw. The left and right halves of the lead screw are provided with threads in opposite directions. Each thread is equipped with a nut. Each nut is rotatably connected to a vertical support rod extending into the air. Each vertical support rod is connected to multiple sets of strawberry planting boxes. The strawberry planting boxes are arranged sequentially at intervals along the axis of the vertical support rod. The middle part of the vertical support rod is connected to a support column.

[0008] Preferably, the support column is a gas spring.

[0009] Preferably, the other end of the strawberry planting box is connected to an auxiliary support rod, and the lower end of the auxiliary support rod is slidably connected to a guide rail, which is arranged parallel to the lead screw.

[0010] Preferably, there are multiple sets of lead screws and guide rails, and adjacent sets of lead screws and guide rails are coaxially connected by couplings.

[0011] Preferably, each vertical strut is equipped with a photosensitive sensor on both the left and right sides, and the photosensitive sensor is connected to a control system, which is used to drive the lead screw to rotate.

[0012] Preferably, the strawberry planting box and the support column are located on opposite sides of the vertical support rod.

[0013] Preferably, both ends of the strawberry planting box are rotatably connected to the vertical support rod and the auxiliary support rod.

[0014] Preferably, the portion between the lead screw and the guide rail is covered with a reflective film.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model uses the rotation of the lead screw to drive the two nuts to move relative to or away from each other, so that the upper ends of the vertical support rods connected by the two nuts move away from or closer to each other. The two vertical support rods and the lead screw form a structure with an inverted triangle or an upright triangle cross section, so that the left and right sides of the strawberry planting box are alternately exposed to the outside to receive sufficient sunlight, effectively coordinating the problem of uneven light intensity in different planting areas, and achieving stable and high-yield high-quality results.

[0016] 2. The photosensitive sensor is connected to the control system to achieve automated control without human intervention, and the adjustment is precise and efficient. Attached Figure Description

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] like Figure 1-4 As shown, this utility model discloses a device for tiered strawberry planting. The device uses a horizontally installed lead screw 3 on the ground. The lead screw has two opposite threads, one left-handed and one right-handed. Each thread is equipped with a nut of the corresponding direction. The upper end of the left nut 1 is rotatably connected to the left vertical support rod 4 via a rotating pin, and the upper end of the right nut 5 is rotatably connected to the right vertical support rod 5 via a rotating pin. Multiple sets of strawberry planting boxes 7 are arranged at intervals from top to bottom along the axis of each vertical support rod on its rear side. A support column 2 is rotatably connected to the middle of the front side of each vertical support rod. The support column is a gas spring that can rise and fall under pressure.

[0022] The right end of the lead screw 3 is connected to the drive motor 8. The drive motor drives the lead screw 3 to rotate in the forward or reverse direction. The left nut 1 and the right nut 6 move to the middle or both sides respectively under the limiting action of the vertical support rod, thereby driving the two vertical support rods to rotate clockwise or counterclockwise around the upper end of the gas spring, so that the strawberries on both sides of the strawberry planting box 7 have the opportunity to be exposed to the outside and receive sufficient sunlight.

[0023] To improve the stability of the device, an auxiliary support rod 9 is connected to the rear end of the strawberry planting box 7. A sliding sleeve is installed at the lower end of this auxiliary support rod, which is fitted onto the outside of the guide rail and can slide left and right along the rail. The guide rail and the lead screw are arranged parallel to each other. To ensure that the strawberry planting box 7 is always vertically aligned, both the front and rear ends of the strawberry planting box are rotatably connected to the vertical support rod and the auxiliary support rod. With this configuration, when the vertical support rod tilts to the left or right, the strawberry planting box 7 maintains self-adjusting balance under gravity, and the left and right sides of the strawberry planting box remain stably positioned at the outer ends of the vertical support rod.

[0024] To achieve automatic adjustment and free up labor, photosensitive sensors are installed on both sides of each vertical support rod. The light parameters detected by the photosensitive sensors reflect the light conditions on the surface of the strawberries inside the strawberry planting box 7 on that side. The photosensitive sensors are connected to the control system, which stores a standard value in advance. When the light signal sent by the photosensitive sensors to the control system deviates from the standard value, the system determines whether to supplement light or block light, and then sends a command to the drive motor 8 to drive the lead screw to rotate forward or reverse, thereby adjusting the light in each part of the strawberry planting box in real time.

[0025] like Figure 5 and Figure 6 As shown, when applied to large-scale greenhouse planting, the two adjacent sets of lead screws 3 and guide rails can be connected to each other through couplings, so that one drive motor can control the movement of multiple sets of vertical support rods, thereby driving multiple sets of strawberry planting boxes to adjust the light conditions and form a large-scale management mode.

[0026] Meanwhile, this application also lays a reflective film between the lead screw 3 and the guide rail. For the sunlight that is partially blocked by the strawberry planting box above but shines on the ground, the reflective film can also supplement the light for the strawberries.

[0027] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention.
