Description

Technical Field

[0001] This utility model relates to the field of drainage technology for crop planting, and in particular to a drainage structure for a sprout seedling basket. Background Technology

[0002] The drainage structure of the sprout seedling basket is a functional component set at the bottom and sides of the basket to drain excess water from the basket. It includes drainage holes, guide channels, filter screens and matching water collection devices. The drainage holes are the channels for water to flow out, the guide channels guide the water flow to converge at the drainage holes, and the filter screen covers the inside of the drainage holes to intercept the seedling substrate and sprout roots, preventing them from clogging the drainage channels as they are discharged with the water.

[0003] This drainage structure plays a crucial role in the quick and convenient drainage after a seedling cultivation cycle. When the seedling cultivation cycle ends and the seedling baskets need to be cleaned, the drainage structure can quickly drain the residual irrigation and washing water from the baskets without the need for manual dumping, reducing operational steps. For multi-layered stacked seedling baskets, a reasonable drainage structure allows the drainage from the upper baskets to be directly guided into the lower water collection device, preventing water overflow and contaminating the operating environment, improving cleaning efficiency, and making it suitable for batch processing in large-scale cultivation scenarios.

[0004] Currently, the drainage structure of sprout seedling baskets on the market has limitations. In terms of filtration structure and debris interception, existing filters are mostly flat meshes with a single aperture, which cannot effectively distinguish and intercept substrate particles and small roots. Either the substrate is lost due to the aperture being too large, or the root system is entangled and blocked due to the aperture being too small. In terms of anti-clogging and cleaning efficiency, the substrate often accumulates on the surface of the filter due to water flow, forming silt and reducing the drainage speed. Moreover, cleaning the filter structure requires multiple steps of disassembly to clean the filter itself and its internal structure, which affects the overall drainage efficiency.

The output end of the rotating motor 393 passes through the bottom of the drain pump housing 391 and is fixedly connected to the bottom center of the front internally engaged gear 394, so that the rotating motor 393 can drive the front internally engaged gear 394 to rotate when it is working.

[0053] Working principle: The drainage structure of this sprout seedling basket, through the coordinated operation of the filter drainage mechanism 3 and the bottom cleaning mechanism 4, realizes the drainage of excess water during the sprout seedling process and the cleaning of residual water at the bottom of the basket, ensuring that the sprouts grow in a suitable humidity environment.

[0054] During the filtration and drainage process, excess water in the cultivation basket 31 first flows into the main drain pipe 34 through the two drain openings 32 at the bottom right side. The main drain pipe 34 guides the water into the filter housing 35. The two inner filter screens 36 inside the housing filter impurities in the water. The filtered water enters the drainage pump assembly 39 through the connecting water pipe 38.

[0055] In the drainage pump assembly 39, the rotating motor 393 starts and drives the front inner engaging gear 394 to rotate. Because the two inner engaging gears 394 mesh with each other, the rear inner engaging gear 394 rotates accordingly. Under the action of gear rotation, water is pumped out and discharged. When it is necessary to clean the impurities inside the filter, the filter opening 37 can be slid to operate. The culture plate 3101 in the culture assembly 310 is placed in the culture basket 31. The culture slot 3102 on the top is used to cultivate sprouts. The sprouts can be easily picked up and put in by sliding the culture plate 3101. The frame handle assembly 311 makes it easy to move the culture basket 31.

[0056] The working process of the bottom cleaning mechanism 4 is as follows: the bottom connecting piece 41 is fixed to the outer wall of the main support frame 2 to provide support for the entire mechanism; when it is necessary to clean the residual moisture at the bottom of the cultivation basket 31, the hydraulic device 43 is activated, and the hydraulic rod extension 44 on the left side works in conjunction with the hydraulic front push rod 45 on the right side to push the cleaning absorbent sponge 46 to the right; the cleaning absorbent sponge 46 enters the bottom of the basket through the bottom opening 47 on the left side of the cultivation basket 31 to absorb the remaining moisture; after cleaning is completed, the hydraulic device 43 drives the hydraulic front push rod 45 to retract, removing the cleaning absorbent sponge 46 from the bottom of the basket; the side connecting key 42 is used to fix the hydraulic device 43 to ensure its stable position during operation;

[0057] Through the sequential action of components such as the drain opening 32, main drain pipe 34, filter housing 35, inner filter screen 36, and drain pump assembly 39 in the filtration and drainage mechanism 3, excess water in the cultivation basket 31 is efficiently filtered and discharged, preventing water accumulation that could lead to the rotting of the sprouts. At the same time, the hydraulic device 43 and hydraulic push rod 45 in the bottom cleaning mechanism 4 drive the cleaning and water-absorbing sponge 46 to absorb residual water at the bottom of the basket, further ensuring that the basket remains dry.
