Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, specifically a sweet potato seedling cultivation device. Background Technology

[0002] Sweet potatoes originated in South America and the Greater and Lesser Antilles. They are now widely cultivated in tropical and subtropical regions around the world, but have also been successfully grown in some northern regions such as Heilongjiang Province. They are commonly cultivated in most parts of China. Sweet potatoes are highly adaptable, prefer warm and sunny conditions but are not frost-resistant. They are drought-resistant and alkali-tolerant, and are suitable for planting in fertile and well-drained sandy loam soil. They are an easy crop to harvest.

[0003] Chinese utility model patent CN217160706U, published on August 12, 2022, discloses a movable soilless seedbed for virus-free sweet potatoes. The seedbed includes a partition that divides the interior into a seedling chamber and a liquid storage chamber from top to bottom. Multiple thin tubes pass through the partition, with open lower ends communicating with the liquid storage chamber and closed upper ends extending into the seedling chamber. Multiple drainage holes are located on the walls of the tubes extending into the seedling chamber. A floating plate that can slide up and down is installed within the liquid storage chamber and is connected to a driving device. As the floating plate moves upward, water in the liquid storage chamber is squeezed into the thin tubes and overflows from the drainage holes, achieving uniform irrigation of the planting substrate in the seedbed and reducing irrigation blind spots. The driving device uses an electromagnet to generate magnetism, thereby driving the floating plate upward. This invention features a compact structure and convenient operation, eliminating the need for manual watering, saving significant labor costs, and improving the cultivation quality of sweet potato seedlings.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the seedling beds of the existing technology are placed horizontally on the ground and the height is adapted to the operating height of human hands, which results in a large area occupied and a small number of devices placed in the same space, making it difficult to maximize the use of the area in the jade factory. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of existing seedling beds, which are placed horizontally on the ground and are at a height that is adapted to the operating height of human hands, resulting in a large area occupied and a small number of devices that can be placed in the same space, making it difficult to maximize the use of the space in the factory. This invention provides a sweet potato seedling cultivation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a sweet potato seedling cultivation device, comprising an elevated frame; a plurality of fourth connecting pins are inserted into the elevated frame through openings; seedling pots are sleeved on the fourth connecting pins; an inclined plate is fixedly connected to the lower end of the elevated frame; first connecting pins are symmetrically inserted into the lower end of the elevated frame; a fixed base is sleeved on the first connecting pin; and a hydraulic drive unit is provided between the fixed base and the inclined plate.

[0008] Furthermore, the hydraulic drive unit includes a third connecting pin inserted into the inclined plate; a hydraulic rod is sleeved on the third connecting pin; a second connecting pin is inserted into the lower end of the hydraulic rod; the second connecting pin is inserted into the array hole; the array hole is formed on the fixed base.

[0009] The sweet potato seedling cultivation device provided by this utility model has the following beneficial effects:

[0010] 1. This utility model uses a fixed base to stably fix the frame to the ground. Then, driven by a hydraulic drive unit, the raised frame can change from a vertical state to a horizontal state, thereby transforming multiple vertically arranged seedling pots into a horizontal state at a low height from the ground. This facilitates seedling cultivation operations within the multiple seedling pots. After the operation is completed, the hydraulic drive unit changes the raised frame from a horizontal state to a vertical state, thereby reducing the projected area on the ground. This allows for the simultaneous cultivation of a large number of sweet potato seedlings within the same area of ​​the factory. At the same time, the vertically arranged seedling pots can receive ample sunlight and air, reducing adverse factors in seedling cultivation.

[0011] 2. This utility model utilizes an energized hydraulic rod to pull the third connecting pin and the inclined plate to rotate around the first connecting pin, thereby slowly tilting the vertical support frame to a horizontal position. This lowers the height of the seedling pots, facilitating seedling cultivation. After operation, the hydraulic rod is activated, pushing the third connecting pin and the inclined plate to rotate around the first connecting pin, changing the position from horizontal to vertical. This reduces the space occupied on the ground, allowing for the simultaneous cultivation of a large number of sweet potato seedlings within the same area. During the tilting motion, the seedling pots remain vertical due to gravity and the spacing between them, preventing them from tipping over. The combination of multiple array holes at various heights with the first connecting pin allows for adjustment of the horizontal height of the support frame, accommodating sweet potato seedling cultivators of different heights.

[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0020] Please see Figure 1-3 As shown, a sweet potato seedling cultivation device includes an elevated frame 1; multiple fourth connecting pins 11 are inserted into the elevated frame 1 through openings; seedling pots 12 are sleeved on the fourth connecting pins 11; an inclined plate 6 is fixedly connected to the lower end of the elevated frame 1; first connecting pins 2 are symmetrically inserted into the lower end of the elevated frame 1; a fixed base 3 is sleeved on the first connecting pin 2; a hydraulic drive unit is provided between the fixed base 3 and the inclined plate 6; the device is stably fixed to the ground by the fixed base 3, and then, driven by the hydraulic drive unit, the elevated frame 1 can change from a vertical state to a horizontal state, thereby changing the multiple vertically arranged seedling pots 12 to a horizontal state at a low height from the ground, thus facilitating seedling cultivation operations within the multiple seedling pots 12. After the operation is completed, the hydraulic drive unit changes the elevated frame 1 from a horizontal state to a vertical state, thereby reducing the projected area on the ground, allowing a large number of sweet potato seedlings to be cultivated simultaneously in a factory of the same area; at the same time, the vertically arranged seedling pots 12 can fully receive sunlight and air, reducing unfavorable factors for seedling cultivation.

[0021] See Figure 2 and 3 The hydraulic drive unit includes a third connecting pin 7 inserted into the inclined plate 6; a hydraulic rod 8 is sleeved on the third connecting pin 7; a second connecting pin 5 is inserted into the lower end of the hydraulic rod 8; the second connecting pin 5 is inserted into the array hole 4; the array hole 4 is opened on the fixed base 3. When the hydraulic rod 8 is energized, it pulls the third connecting pin 7 and the inclined plate 6 to rotate around the first connecting pin 2, thereby slowly tilting the vertical elevated frame 1 to a horizontal state, thus lowering the height of the seedling pot 12 to facilitate seedling operation. After the operation is completed, the hydraulic rod 8 is activated, thereby pushing... The third connecting pin 7 and the inclined plate 6 rotate around the first connecting pin 2, changing from a horizontal state to a vertical state, thereby reducing the space occupied on the ground. Thus, a large number of sweet potato seedlings can be raised simultaneously in the same area. During the tilting motion, the seedling pot 12 can always remain vertical under the action of gravity and the spacing between the seedling pots 12, so as not to tip over. The combination of the array holes 4 at multiple heights and the first connecting pin 2 can adjust the horizontal height of the frame 1, thereby adapting to sweet potato seedling raisers of different heights.

[0022] See Figure 3 The fixed base 3 has holes for inserting multiple fasteners 9. By inserting the anchor rod or pre-embedded nut into the fasteners 9, it can be stably fixed to the ground.

[0023] See Figure 3 The fixed base 3 is provided with an alignment hole 10. The alignment hole 10 allows for easy insertion of a straight shaft into the alignment hole 10 during the installation of the fixed base 3 to achieve alignment and parallelism.

[0024] See Figure 1 The seedling trays 12 are made of plastic, which makes the overall weight of multiple seedling trays 12 low and the hydraulic requirements of the hydraulic rods 8 low, so that they can be miniaturized and accommodated in the gap of the fixed base 3.

[0025] See Figure 1 The seedling tray 12 has multiple drainage holes 13, which can drain the water that cannot be retained in the seedling tray 12 in time, so as to prevent the sweet potato seedlings from being suffocated by waterlogging.
