Description

Technical Field

[0001] This utility model is a sowing auxiliary mechanism for seedling cultivation in nutrient cups, belonging to the field of agriculture. Background Technology

[0002] Nutrient cup seedling cultivation is a method that uses specially designed nutrient cups to provide seedlings with an independent growth environment. It is widely used in the cultivation of vegetables, flowers, and trees due to its advantages such as excellent water and fertilizer retention, effective root protection, and high transplant survival rate. During sowing, the prepared culture medium is first filled into the nutrient cup. Then, a hole is poked in the medium with a pestle, and the seed is placed into the hole. Because the culture medium itself has a certain degree of moisture, a small amount of medium will adhere to the surface of the pestle after it is inserted. When this pestle with residual medium is used to poke a hole in the culture medium of another nutrient cup, on the one hand, the adhered medium will cause the newly poked hole to be irregular in shape, affecting the seed burial effect; on the other hand, to avoid this situation, the residual medium on the surface of the pestle needs to be cleaned frequently by hand, which undoubtedly slows down the overall sowing progress and reduces work efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sowing auxiliary mechanism for nutrient cup seedling cultivation, so as to solve the problems mentioned in the background technology. This utility model enables convenient removal of the culture medium attached to the tamping rod.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sowing auxiliary mechanism for seedling cultivation in nutrient cups, comprising: The cup body has an open top. The tray is fitted onto the lower end of the cup. The bottom plate is located on the underside of the pallet and is connected to the pallet via an adjusting mechanism; The lower end of the vertical part of the L-shaped frame is mounted on the upper surface of the base plate, and a lower ring is installed at the end of the horizontal part of the L-shaped frame. A tamping rod is inserted into the lower ring and is arranged concentrically with the tray. An upper ring is fitted on the upper end of the tamping rod and is connected and fixed to the tamping rod. A spring is provided between the upper ring and the lower ring and is fitted on the tamping rod. The shovel sleeve is located on the lower side of the lower ring and is fitted onto the lower end of the tamping rod. The shovel sleeve is connected and fixed to the L-shaped frame.

[0005] Furthermore, the adjusting component includes a column rod, which is installed at the center of the lower surface of the tray. A column cylinder is sleeved at the lower end of the column rod, and the lower end of the column cylinder is connected and fixed to the base plate. A positioning screw for limiting the relative position of the column rod and the column cylinder is threadedly connected to the outer surface of the upper end of the column cylinder.

[0006] Furthermore, a shaft hole is provided at the upper part of the outer surface of the column, and a threaded sleeve is provided on the outer side of the shaft hole, which is concentrically arranged with the shaft hole. One end of the threaded sleeve is connected and fixed to the column, and the positioning screw is threadedly connected inside the threaded sleeve. One end of the positioning screw passes through the shaft hole and contacts the column rod.

[0007] Furthermore, two fixing holes are provided on the upper surface of the base plate, and the two fixing holes are located on both sides of the vertical part of the L-shaped frame along the length direction of the base plate.

[0008] Furthermore, a conical cover that is wider at the top and narrower at the bottom is fixed to the upper end of the shovel sleeve. The conical cover is fitted onto the tamping rod. A ring pipe is provided in the upper part of the conical cover. The ring pipe is fitted onto the tamping rod. Multiple seepage holes are evenly opened on the lower part of the outer surface of the ring pipe. The ring pipe is connected to a reducing pipe through a thin pipe. A valve is installed at the end of the reducing pipe away from the thin pipe. A water storage cylinder is installed on the upper surface of the horizontal part of the L-shaped frame. The upper end of the water storage cylinder is open. The valve is installed at the bottom of the water storage cylinder.

[0009] Furthermore, a connecting plate is installed at the bottom of the water storage tank, and a support plate is installed on the lower surface of the connecting plate. The lower end of the support plate is connected and fixed to the horizontal part of the L-shaped frame.

[0010] Furthermore, a horizontal plate is installed on the vertical part of the L-shaped frame, and the end of the horizontal plate away from the L-shaped frame is connected and fixed to the soil shovel sleeve.

[0011] Furthermore, a strip-shaped opening is provided on one side of the vertical part of the L-shaped frame, and the strip-shaped opening is arranged vertically.

[0012] The beneficial effects of this utility model are: 1. After the tamping rod descends and pokes the hole, it automatically resets under the action of the spring. During the reset process, the shovel sleeve fixed on the L-shaped frame scrapes against the surface of the tamping rod, thoroughly removing the adhering culture medium. Compared with the traditional manual cleaning method, this eliminates the step of cleaning each hole, shortens the sowing time per cup, and avoids the problem of irregular hole shapes caused by residual culture medium.

[0013] 2. By loosening the positioning screw, the insertion depth of the rod in the column cylinder can be adjusted. At this time, the initial distance between the tray and the tamping rod changes, which can be adapted to cups of different heights. At the same time, for cups of the same specification, by adjusting the height of the tray, it is easy to adjust the depth of the tamping rod inserted into the cup, and to adjust the depth of the tamping rod forming cavities in the culture medium as needed.

[0014] 3. Control the opening degree of the valve so that the water in the water storage tank slowly drips into the conical hood through the channel formed by the thin tube, the ring tube and the seepage hole. Then the water dripping into the conical hood flows into the space between the shovel cover and the tamping rod, so as to moisten the surface of the tamping rod and make it easier for the shovel cover to scrape off the culture medium attached to the tamping rod.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1-4This utility model provides a technical solution: a seeding auxiliary mechanism for nutrient cup seedling cultivation, including a cup body 1 with an open upper end, a tray 2 fitted onto the lower end of the cup body 1, a base plate 3 set on the lower side of the tray 2, a column rod 21 installed at the middle of the lower surface of the tray 2, a column cylinder 23 fitted onto the lower end of the column rod 21, the lower end of the column cylinder 23 being connected and fixed to the base plate 3, and two fixing holes 31 opened on the upper surface of the base plate 3, the two fixing holes 31 being located on both sides of the vertical part of the L-shaped frame 4 along the length direction of the base plate 3. A shaft hole is provided at the upper part of the outer surface of the column 23. A threaded sleeve 22 is provided on the outside of the shaft hole, concentrically arranged with the shaft hole. One end of the threaded sleeve 22 is connected and fixed to the column 23. A positioning screw 24 is threaded into the threaded sleeve 22. One end of the positioning screw 24 passes through the shaft hole and contacts the column rod 21. The threaded sleeve 22 achieves a stable connection between the positioning screw 24 and the column 23. After loosening the positioning screw 24, the column rod 21 can freely extend and retract within the column 23, thereby changing the initial distance between the tray 2 and the tamping rod 6. This design can flexibly adapt to nutrient cups of different heights. For nutrient cups of the same size, the depth of the tamping rod 6 inserted into the cup body 1 can be precisely controlled by adjusting the height of the tray 2. This allows for flexible adjustment of the depth of the cavity formation in the culture medium according to seed type, cultivation needs, etc., ensuring that the cavity depth meets the sowing standard. For example, shallow seeds correspond to shallow cavities, and deep seeds correspond to deep cavities, improving the adaptability and accuracy of sowing operations.

[0018] See Figures 1-4 The lower end of the vertical part of the L-shaped frame 4 is mounted on the upper surface of the base plate 3. A strip-shaped opening 41 is provided on one side of the vertical part of the L-shaped frame 4. The strip-shaped opening 41 is arranged vertically, reducing the material cost of the L-shaped frame 4. A lower ring 42 is installed at the end of the horizontal part of the L-shaped frame 4. The tamping rod 6 is inserted into the lower ring 42, and the tamping rod 6 is concentrically arranged with the tray 2. An upper ring 61 is fitted onto the upper end of the tamping rod 6, and the upper ring 61 is connected and fixed to the tamping rod 6. The upper ring 61 and the lower ring 42... A spring 62 is installed in the middle, and the spring 62 is sleeved on the tamping rod 6. A soil scraper sleeve 5 is set on the lower side of the lower ring 42 and sleeved on the lower end of the tamping rod 6. A horizontal plate 55 is installed on the vertical part of the L-shaped frame 4. The end of the horizontal plate 55 away from the L-shaped frame 4 is connected and fixed to the soil scraper sleeve 5. The horizontal plate 55 serves to connect the soil scraper sleeve 5 and the L-shaped frame 4. When the tamping rod 6 moves downward to complete the hole excavation, the spring 62 sleeved on the tamping rod 6 will release its elasticity, causing the tamping rod 6 to automatically rise and return to its original position. During this process, the soil scraper sleeve 5 fixed on the L-shaped frame 4 will slide relative to the surface of the tamping rod 6, thereby scraping off the culture medium attached to the tamping rod 6. Compared with the traditional method of manually cleaning the tamping rod 6 hole by hole, this design eliminates the extra cleaning step, shortens the sowing time of a single nutrient cup, and effectively avoids the problem of irregular hole shape caused by culture medium residue on the tamping rod 6, ensuring the standardization and consistency of the sowing operation.

[0019] See Figures 1-4The upper end of the shovel sleeve 5 is connected and fixed with a conical cover 53 that is wider at the top and narrower at the bottom. The conical cover 53 is fitted onto the tamping rod 6. A ring pipe 58 is provided in the upper part of the conical cover 53. The ring pipe 58 is fitted onto the tamping rod 6. Multiple seepage holes are evenly opened on the lower part of the outer surface of the ring pipe 58. The ring pipe 58 is connected to a reducing pipe 56 through a thin pipe 57. A valve 51 is installed at the end of the reducing pipe 56 away from the thin pipe 57. A water storage cylinder 54 is installed on the upper surface of the horizontal part of the L-shaped frame 4. A connecting plate 59 is installed at the bottom of the water storage cylinder 54. A support plate 52 is installed on the lower surface of the connecting plate 59. The lower end of the support plate 52 is connected and fixed to the horizontal part of the L-shaped frame 4. The connecting plate 59 increases the connection range between the support plate 52 and the water storage cylinder 54. The upper end of the water storage cylinder 54 is open. The valve 51 is installed at the bottom of the water storage cylinder 54. By adjusting the opening and closing degree of valve 51, the water in the water storage cylinder 54 can be controlled to flow through the passage composed of thin pipe 57, annular pipe 58 and seepage holes, and slowly drip into the conical shroud 53. This dripping water then flows into the gap between the shovel sleeve 5 and the tamping rod 6, creating a moistening effect on the surface of the tamping rod 6. This allows the shovel sleeve 5 to more easily and thoroughly scrape off the attached culture medium when scraping the tamping rod 6, further improving cleaning efficiency and preventing the cultured genes from drying and clumping and leaving residue.
