Description

Technical Field

[0001] This utility model relates to the field of potato sprouting technology, and in particular to a sprouting device for potato cultivation. Background Technology

[0002] Potato seedling cultivation is a planting technique aimed at improving potato planting efficiency and yield through specific methods and steps. Seed potatoes are selected to remove frozen, damaged, diseased, rotten, wilted, and deformed tubers. Then, the seed potatoes are sprouted and placed inside a sprouting device. The sprouting device provides a stable temperature and moisture environment for the seed potatoes to sprout, thereby improving the sprouting rate.

[0003] In potato cultivation, the sprouting stage has a significant impact on seedling survival rate and growth quality. Existing sprouting devices mostly use fixed cultivation pot structures, which suffer from problems such as cumbersome seedling removal, easy damage to seedling roots, inconvenient water management, and difficult cleaning and maintenance. Although some improved designs have been developed, such as detachable cultivation pots or lifting tray structures, these still do not systematically solve the pain points of low efficiency in batch seedling removal, unstable transplant survival rates, and inconvenient impurity removal. Some devices have complex structures but lack practicality, or fail to balance automated operation with cost control, making it difficult to meet the needs of large-scale planting.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Reference Figures 1 to 8 In a preferred embodiment, a sprouting device for potato cultivation includes a cultivation unit 1, a water collection unit 2, a triggering mechanism, and a receiving mechanism 3. The cultivation unit 1 includes a frame 11 and a plurality of flexible sprouting bags 12. The flexible sprouting bags 12 are containers with an open top and a sealed bottom, and a fixing part is provided along the upper edge of the opening. The frame 11 is provided with a hanging mechanism adapted to the fixing part. The flexible sprouting bags 12 are detachably connected to the hanging mechanism through their fixing parts. The water collection unit 2 is located below the cultivation unit 1. The bottom of the flexible sprouting bags 12 is provided with an easy-tear sealing structure 13. The triggering mechanism is fixedly installed on the frame 11 and located below all the flexible sprouting bags 12. The receiving mechanism 3 can be placed inside the water collection unit 2.

[0033] In some embodiments, the frame 11 is a grid structure, which includes a peripheral frame 111 and a plurality of horizontal and vertical beams 112 connected to the peripheral frame 111; the triggering mechanism is one or more rigid rods, which are mounted on the horizontal and vertical beams 112.

[0034] The suspension mechanism is a device for detachably securing the flexible germination bag 12, and it has various implementations to adapt to different application requirements:

[0035] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the fixing part is a bag lip 121 formed by folding the upper edge of the flexible germination bag 12 outwards. The suspension mechanism consists of suspension holes 14 on two corresponding sides of the upper surface of the horizontal and vertical beams 112. The outer dimensions of the bag lip 121 are larger than the diameter of the suspension hole 14. The bag lip 121 passes through the suspension hole 14 and is snapped onto the edge of the hole through its folding structure. In some embodiments, the edge of the suspension hole 14 is provided with an upwardly extending flange 141. This method has a simple structure, low cost, and is suitable for standardized production.

[0036] like Figure 5 and Figure 6As shown, as another more flexible implementation, the suspension mechanism consists of multiple parallel slide rails 17 arranged on the frame 11, each slide rail 17 having a T-slot; the fixing part is a slider 122 located on the upper edge of the flexible germination bag 12, and the slider 122 has a locking nut that cooperates with the T-slot. This method is suitable for scientific research or scenarios where frequent adjustments to planting density are required.

[0037] like Figure 7 and Figure 8 As shown, as a compromise implementation, the suspension mechanism consists of hanging rods 18 arranged in an array on the frame 11; the fixing part is a hanging ear 123 provided on the upper edge of the flexible germination bag 12, which is sleeved on the hanging rod 18. This method achieves a good balance between flexibility and cost.

[0038] In some embodiments, the flexible germination bag 12 is made of non-woven fabric or biodegradable flexible material, and its sidewalls are provided with uniformly distributed breathable micropores.

[0039] like Figure 2 As shown, in some embodiments, the easy-tear sealing structure 13 is a pre-indentation line, an easy-tear seam, or an opening sealed with a water-soluble adhesive.

[0040] See also Figure 1 In some embodiments, two handles are provided opposite to each other on the frame 11.

[0041] Specifically, the peripheral frame 111 is a rectangular frame forming the four sides of the outer frame, usually made of square tubing or profiles, and is the main load-bearing structure. The horizontal and vertical beams 112 are reinforcing ribs that are connected inside the peripheral frame and intersect each other perpendicularly. They divide the entire frame into several uniformly sized grids. The grid structure of the frame 11 provides suspension points for all the flexible germination bags 12. It bears the total weight of all the flexible germination bags 12 filled with soil, as well as the frame itself, and transfers it to the water collection unit 2. It ensures that all the flexible germination bags 12 remain in a neat array during movement and operation, and do not scatter. Through the handle, the user can operate all the flexible germination bags 12 in the entire cultivation unit 1 at the same time. The flexible germination bag 12 is usually cylindrical or square-pyramidal (larger at the top and smaller at the bottom, for easy demolding and removal). During installation, the bag lip 121 is pinched together by hand, passed through the hanging hole 14 from below, and then released. The bag lip 121 will spring back to its original shape and lock onto the edge of the hole. During disassembly, simply pinch the bag lip 121 closed again by hand to remove it from the hanging hole 14. As an independent unit, it holds soil and a single seed potato, preventing root entanglement. The design of the easy-tear seal structure 13 at the bottom of the flexible sprouting bag 12 allows the root ball to be completely and undamagedly removed from the container when taking the seedlings. The hanging hole 14, in conjunction with the bag lip 121, enables quick, tool-free connection and separation between the flexible sprouting bag 12 and the frame 11. The greater the weight of the flexible sprouting bag 12 and the soil, the greater the static friction between the bag lip 121 and the edge of the hanging hole 14, resulting in a more secure connection. The easy-tear seal structure 13 is a pre-fabricated weak line machined into the bottom material of the flexible sprouting bag 12. The easy-tear sealing structure 13 can take the form of a pre-indentation line (thinning the material locally through hot or cold pressing with a mold), a micro-perforation line (densely piercing a row of micro-holes with a needle), a laser-etched line (using a laser to ablate shallow marks on biodegradable material), or a sealing sheet glued with a water-soluble adhesive. The easy-tear sealing structure 13 is integrally formed or post-processed with the flexible germination bag 12, located in the center or a specific area of ​​the bag bottom. During the seedling stage, its strength is sufficient to reliably support the weight of the moist soil inside the flexible germination bag 12, preventing leakage. Because its strength is much lower than other parts of the flexible germination bag 12, when subjected to the scraping force of the triggering mechanism, stress will concentrate here, causing the easy-tear sealing structure 13 to open neatly and completely along a predetermined trajectory, without causing irregular tearing of other parts of the bag. It also ensures that the opening size is sufficient to allow the root ball to pass smoothly and completely, avoiding jamming or scattering due to obstructed opening. The handle is an arc-shaped handle installed on the perimeter frame 111 along the long side of the frame 11, which provides the operator with a clear point of force application, making it easy to lift and move the entire cultivation unit 1 smoothly.The triggering mechanism, typically one or more straight rigid rods (such as round rods or flat steel), has a length matching the width of the easy-tear sealing structure 13. Its cutting edge is not sharp like a knife, but rather designed with a smooth but angular edge (such as the edge of a rectangular cross-section rod) to avoid cutting unintended areas of the bag. It is rigidly fixed to the corresponding horizontal and vertical beams 112 of each flexible germination bag 12 via brackets and using bolts or welding, located directly below all flexible germination bags 12 and above the top of the receiving mechanism 3. Its installation height is precisely calculated to ensure a gap of several millimeters between the bottom of the flexible germination bag 12 and the triggering mechanism when the bag is filled with soil. This triggering mechanism converts the vertical upward movement of the cultivation unit 1 into a horizontal shearing force on the bottom of the flexible germination bag 12. A single rigid rod acts simultaneously on all the flexible germination bags 12 in a row, ensuring that the bottoms of all bags are cut open instantaneously.

[0042] In some embodiments, the water collection unit 2 is a shallow dish or low box with an open top, a drain valve 21 at the bottom, and a retractable filter cake box 22 inside. Specifically, the water collection unit 2 is rectangular, and its planar dimensions match or are slightly larger than the cultivation unit 1 above it. It is used to collect excess water and nutrient solution seeping from the flexible germination bag 12, preventing environmental pollution. The drain valve 21 is a normally closed valve, vertically installed on the opening at the lowest point of the bottom plate of the water collection unit 2, used to orderly discharge the waste liquid collected at the bottom of the water collection unit 2, which can be directly connected to a hose to lead to the sewer. The filter cake box 22 is a drawer-type or basket-type mesh container with a handle. It is placed inside the water collection unit 2, usually on the side or front end near the drain valve 21, and is used to intercept solid impurities such as soil particles, substrate debris, and algae that seep out from the flexible germination bag 12 with the water, protecting the drain valve 21 and its downstream pipes from being blocked by impurities. Simply remove the filter cake box 22 periodically, empty and rinse the impurities; there is no need to clean the entire water collection unit 2, making maintenance extremely convenient.

[0043] In some embodiments, the receiving mechanism 3 is an open-top collection basket, the depth of which is greater than the length of the flexible germination bag 12. The inner bottom surface of the collection basket is provided with a cushioning pad 31; the surface of the cushioning pad 31 is provided with limiting recesses 32 corresponding to the array distribution at the bottom of the flexible germination bag 12. Specifically, the receiving mechanism 3 is an open-top, solid-bottom or meshless basket or tray, its size adapted to the internal space of the water collection unit; during seedling collection, it is temporarily placed inside the water collection unit 2, located directly below the triggering mechanism; it is separable from the water collection unit and has no fixed connection. During seedling collection, the receiving mechanism 3 receives all root clumps falling from the flexible germination bag 12. After collection, it can be directly used as a transport tool to transport the entire batch of seedlings to the field for transplanting, realizing the integration of "collection" and "transportation" functions. The cushioning pad 31 is a soft padding layer laid at the bottom of the collection basket, made of materials such as sponge, EVA foam, non-woven fabric, or rubber. It can be permanently attached or placed inside as a replaceable consumable. It effectively absorbs the impact of the root ball falling, preventing the soil ball from breaking apart or the seedling roots from being damaged. Some materials (such as moistened non-woven fabric) can also provide moisture retention for the root ball in a short time. The positioning recesses 32 are an array of recesses pressed or molded on the surface of the cushioning pad 31. Their distribution, size, and shape correspond perfectly to the array of the flexible germination bag 12 above. They are used to ensure that each falling root ball lands in a fixed recess, preventing seedlings from colliding and piling up. The sides of the positioning recesses 32 provide additional lateral support and protection for the root ball.

[0044] Working principle:

[0045] Before operation: Place the cultivation unit 1 above the water collection unit 2, ensuring that the bottom of the flexible sprouting bag 12 is at an appropriate distance from the triggering mechanism. Fill the flexible sprouting bag 12 with cultivation substrate and seed potatoes, and proceed with normal seedling cultivation. During irrigation, excess water seeps into the water collection unit 2 and is discharged through the drain valve 21, while impurities are intercepted by the filter residue box 22.

[0046] During operation: When seedling cultivation is complete and seedlings need to be removed, the receiving mechanism 3 is placed inside the water collection unit 2, located below the triggering mechanism. The operator holds the handle and lifts the cultivation unit 1 upwards, causing the flexible germination bag 12 to rise synchronously with the frame 11. During the ascent, the easy-tear sealing structure 13 at the bottom of the flexible germination bag 12 comes into contact with and is torn by the fixed triggering mechanism. Under the action of gravity, the root ball inside the bag falls intact into the limiting recess 32 of the receiving mechanism 3, and the cushioning pad 31 effectively prevents the impact of the fall.

[0047] After the work is completed: Remove the receiving mechanism 3 from the water collection unit 2 to obtain neatly arranged seedlings, which can be directly transported to the field for transplanting. Empty the filter residue box 22 in the water collection unit 2 to prepare for the next seedling cultivation operation.
