Description

Technical Field

[0001] This utility model belongs to the technical field of seedling equipment, and more specifically, relates to an automatic cleaning device for seedling trays. Background Technology

[0002] Seedling cultivation is a method of raising seedlings in specially designed seedbeds for transplanting into production fields. It is a method capable of large-scale seedling cultivation, applicable to crops such as rice, sweet potatoes, vegetables, fruit trees, and flowers. Compared to direct seeding, its advantages lie in creating the necessary environmental conditions based on the characteristics of crop seedling growth and development, employing advanced seedling techniques, and implementing centralized management to cultivate high-quality and abundant seedlings. Seedling cultivation allows for earlier sowing in unsuitable growing seasons, extending the crop's growing period and promoting earlier maturity. Furthermore, this method facilitates meticulous management, promoting robust seedling growth and strong vitality, laying a solid foundation for high-yield and high-quality production.

[0003] Seedling trays, a common tool in seedling cultivation, serve the core function of providing a suitable environment for seed germination and seedling growth, while facilitating large-scale management and transplanting. Seedling trays typically include multiple independent cells, each allowing for individual sowing to avoid interference between seeds and prevent seedling roots from intertwining. During transplanting, seedlings can be removed intact, reducing root breakage and improving transplant survival rates.

[0004] After seedling cultivation, the seedling trays generally need to be cleaned and reused. Traditional cleaning mainly relies on manual labor, which is not only labor-intensive but also inefficient, clearly failing to meet the needs of modern production. Therefore, a series of automatic cleaning devices for seedling trays have emerged on the market.

[0005] For example, patent CN202824041U discloses a seedling tray cleaning device. This application uses a water spray nozzle on the placement side of the floating tray on a cleaning bed. As water is sprayed from the nozzle, it pushes the floating tray towards the other side of the cleaning bed. A water spray pipe is installed on the side of the cleaning bed, with its opening suspended above the bed. The water outlet of the pipe is directed towards the seedling tray removal side of the cleaning bed. Thus, the water sprayed from the pipe can both rinse and disinfect the surface of the floating tray and continue to exert a force on the floating tray, causing it to move towards the seedling tray removal side, completing a continuous motion.

[0006] For example, patent CN222268149U discloses an automatic cleaning device for seedling trays. This application cleans each tray individually, efficiently removing impurities and residues, significantly improving cleaning quality and efficiency. The drying device ensures the trays dry quickly after cleaning, preventing bacterial growth or disease caused by moisture retention during subsequent storage. The pressure roller assembly presses the trays firmly during cleaning, effectively preventing them from flipping or shifting under high-pressure water flow, ensuring the stability and reliability of the cleaning process. This device achieves an automated and continuous cleaning process, reducing labor intensity and improving operational efficiency.

[0007] The aforementioned applications all design technical improvements to seedling tray cleaning devices. However, due to the unique structure of seedling trays, which are generally porous, conventional rinsing methods are not very effective when plant roots become entangled in the holes, easily leading to incomplete cleaning. Therefore, the industry still needs more diverse and sophisticated designs to further improve the cleaning effect of seedling trays. Utility Model Content

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 As shown, an automatic cleaning device for seedling trays in this embodiment includes a frame 100 and a cleaning box 200 mounted on the frame 100; the cleaning box 200 is provided with a conveying mechanism 300 and a high-pressure rinsing component 400 and a low-pressure rinsing component 500 arranged sequentially along the conveying direction of the conveying mechanism 300.

[0027] The frame 100 serves as the mounting base for the entire cleaning device; the conveying mechanism 300 is used to support and transport the seedling trays; the high-pressure rinsing component 400 is mainly used to perform high-pressure rinsing on hard-to-clean areas of the seedling trays (e.g., inside the holes); while the low-pressure rinsing component 500 is used to rinse the seedling trays in all directions.

[0028] In some embodiments, since the frame 100 needs to support the weight of the entire cleaning device, it is made of steel and can be welded from 45# steel or I-beams. The surface of the frame 100 can also be coated with anti-corrosion paint. Alternatively, the frame 100 can be made of cast iron, which not only has good corrosion resistance but also good stability.

[0029] In other embodiments, the cleaning tank 200 includes a tank body 210 and a cover 220. The tank body 210 has a tapered bottom to facilitate water collection. The bottom of the tank body 210 also has a drain hole for drainage. The cover 220 covers the area where the high-pressure rinsing assembly 400 and the low-pressure rinsing assembly 500 are located, preventing water from splashing everywhere during rinsing.

[0030] Preferably, the cover 220 and the housing 210 are detachably connected to facilitate maintenance of the flushing components inside the housing 210. The detachable connection can be any existing technology, such as snap-fit, plug-in, or hinge connection, and is not specifically limited herein.

[0031] For ease of description below, the conveying direction of the conveying mechanism 300, that is, the length direction of the conveying mechanism 300, is defined as longitudinal, and the width direction of the conveying mechanism 300 is defined as transverse.

[0032] refer to Figure 2 , Figure 3 , Figure 4 As shown, in one embodiment of the high-pressure rinsing assembly 400, the high-pressure rinsing assembly 400 includes a first water spray pipe 410 and a plurality of first nozzles 420 disposed on the first water spray pipe 410. The first water spray pipe 410 is horizontally positioned above the conveying mechanism 300, and is connected to a first water pump 450 via a pipe. The first water pump 450 is disposed in a clean water tank 460 located below the cleaning tank 200.

[0033] Preferably, the first water pump 450 can be a high-pressure water pump from the prior art to further increase the rinsing pressure of the first nozzle 420 to ensure the rinsing effect.

[0034] In some embodiments, the first water spray pipe 410 is provided with a plurality of mounting holes along its axial direction, and the mounting holes are equipped with first nozzles 420 or plugs 430. This design allows for adjustment of the flushing position and pressure by adjusting the number and position of the first nozzles 420, which can effectively improve the flushing accuracy and flushing intensity of the cavities, thereby further enhancing the flushing effect on the cavities.

[0035] In other embodiments, two first water spray pipes 410 are arranged longitudinally, and the first nozzles 420 on the two first water spray pipes 410 are staggered and their spraying directions are far apart. The deviation angle α of the first nozzles 420 is 10-30°, for example, 12°, 18°, 26°, etc. In this embodiment, by optimizing the orientation and relative position of the first nozzles 420, the rinsing area can be effectively increased, thereby further improving the rinsing effect.

[0036] Meanwhile, brushes 600 can be provided on both sides of the conveyor line 310 to improve the cleaning effect on both sides of the seedling trays. Preferably, the brushes 600 are rotating. That is, the brushes 600 rotate as the seedling trays move to reduce the obstruction effect on the seedling trays in the conveying state.

[0037] Furthermore, both ends of the first water spray pipe 410 can be supported by telescopic brackets 440 to facilitate height adjustment of the first water spray pipe 410. The telescopic brackets 440 can be fixed inside the cleaning tank 200, and these telescopic brackets 440 are existing technologies, such as telescopic rods.

[0038] refer to Figure 2 , Figure 5 As shown, in one specific embodiment of the low-pressure flushing assembly 500, the low-pressure flushing assembly 500 includes a second water spray pipe 510 and several second nozzles 520. The second water spray pipe 510 has an overall annular structure and multiple pipes are arranged along the moving direction of the conveyor line 310, for example, two, three, or even more. Simultaneously, the multiple second water spray pipes 510 are connected to a second water pump 530 via pipes, and the second water pump 530 is disposed within a circulating water tank 540.

[0039] Multiple second nozzles 520 are distributed around the second water pipe 510, so that the seedling trays being transported will pass through the annular channel formed by several second nozzles 520, so as to achieve all-round rinsing of the seedling trays.

[0040] In some embodiments, the circulating water tank 540 is connected to the cleaning tank 200 via a pipe, allowing for the recycling of the rinsing water within the cleaning tank 200. Of course, to ensure the cleanliness of the circulating water, a filter screen can be installed at the inlet of the circulating water tank 540.

[0041] Furthermore, a heating rod can be installed in the circulating water tank 540 to heat the rinsing water (especially when the air temperature is low) to further improve the rinsing effect. Simultaneously, a temperature sensor can be installed in the circulating water tank 540 for real-time monitoring of the water temperature. Alternatively, a heating rod and temperature sensor can also be installed in the clean water tank 460.

[0042] Furthermore, some stubborn impurities within the pores have already been dislodged or loosened under the high-pressure rinsing of the first nozzle 420. The second nozzle 520 only needs to ensure thorough rinsing and does not require high pressure. Therefore, the rinsing pressure of the second nozzle 520 can be set lower than that of the first nozzle 420. Consequently, a conventional circulating water pump can be used for the second water pump 530.

[0043] It should also be noted that the flushing pressure of the first nozzle 420 is greater than that of the second nozzle 520, mainly due to two factors: firstly, the first water pump 450 connected to the first nozzle 420 has greater power; secondly, compared to the second water pipe (510) which has a ring of second nozzles 520, the first water pipe (410) has fewer first nozzles 420; therefore, the flushing pressure of the first nozzle 420 is also greater.

[0044] like Figure 2 , Figure 6 As shown, in this embodiment, as a specific implementation of the conveying mechanism 300, the conveying mechanism 300 includes a conveying line 310 for carrying seedling trays and a drive assembly 320 for driving the conveying line 310 to rotate. The drive assembly 320 includes a pair of drive shafts 321 arranged opposite to each other, and two sprockets 322 are provided on the drive shafts 321. The drive shafts 321 are rotatably mounted on the housing 210 through bearing seats 323 at both ends, and at least one drive shaft 321 is connected to a motor. The conveying line 310 includes two sets of transmission chains 311 and a connecting rod 312 disposed between the two sets of transmission chains 311. The transmission chains 311 mesh with the corresponding sprockets 322 to achieve meshing transmission.

[0045] In other embodiments, a plurality of protrusions may be provided at intervals along the conveying direction on the surface of the conveyor line 310 for pushing the seedling trays to move. Of course, the distance between adjacent protrusions must be greater than the dimension of the seedling tray along the conveying direction. At the same time, guide rods may also be provided on both sides of the conveyor line 310, which can be used to guide the movement of the seedling trays and to prevent the seedling trays from detaching from the conveyor line 310 due to the flushing pressure.

[0046] This embodiment presents an automatic cleaning device for seedling trays. Considering the unique structure of the seedling trays, the front side has holes for seedling cultivation, where stubborn impurities easily remain and are difficult to clean. Therefore, a more targeted high-pressure rinsing method is used for precise cleaning. The back and sides are relatively flat and easier to clean, so a ring-shaped, fully enclosed low-pressure rinsing method is used. Simultaneously, both high-pressure and low-pressure rinsing are performed multiple times to effectively ensure the rinsing effect.

[0047] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
