Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically a precision fertilization sleeve for Bletilla striata tubers. Background Technology

[0002] Bletilla striata tuber is the dried tuber of the orchid Bletilla striata, a commonly used traditional Chinese medicine. Its appearance is irregularly flattened round or rhomboid, often with 2-3 claw-like branches, 1.5-5 cm long and 0.5-1.5 cm thick. The surface is grayish-white or yellowish-white, with raised stem scars on the upper surface and traces of connection to another tuber on the lower surface. Around the stem scar, there are several concentric rings and brown dot-like rootlet scars. It is hard and not easily broken; the cross-section is off-white, translucent, and horny. Its medicinal properties include astringency, hemostasis, swelling reduction, and tissue regeneration. Its medicinal properties include treating hemoptysis, hematemesis, external bleeding, carbuncles, boils, and chapped skin. The cultivation of Bletilla striata has strict requirements regarding environmental conditions, soil, and cultivation techniques, directly affecting the yield and quality of its tubers. Bletilla striata prefers a warm, humid, and semi-shaded climate and is intolerant of cold, drought, and direct sunlight. It is suitable for cultivation in subtropical to temperate humid mountainous areas. Strict control of the five core conditions of temperature, light, water, soil, and fertilizer, combined with meticulous field management and pest and disease control, is necessary to achieve high-quality and high-yield tubers.

[0003] Currently, in the cultivation of Bletilla striata, fertilizer sleeves are mostly used to accurately control the amount of fertilizer applied and increase the yield. Although fertilizer sleeves can control the amount of fertilizer applied, they cannot be precisely positioned near the Bletilla striata rhizome when inserted into the soil. They may be inserted above or below the rhizome. Most people rely on personal experience to determine the approximate depth of the fertilizer sleeve, which reduces its practicality. Therefore, we provide a precision fertilizer sleeve for Bletilla striata tubers to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a precision fertilization sleeve for Bletilla striata tubers, including a tube body 1 and a through hole 2 inside the tube body 1. One end of the tube body 1 located at the through hole 2 is connected to a pointed tip 3, and the other end of the tube body 1 is connected to a funnel 4. The outer surface of the tube body 1 contacts a sliding sleeve 5, and one end of the sliding sleeve 5 is connected to a positioning plate 6. The space inside the tube body 1 is used to provide storage space for fertilizer. The funnel 4 facilitates filling fertilizer into the interior of the tube body 1. The pointed tip 3 acts as a soil-breaking tool, making it easy to insert the tube body 1 into the soil. The sliding sleeve 5 supports the positioning plate 6, maintaining the stability of the positioning plate 6. The positioning plate 6 provides resistance to the tube body 1, limiting the movement of the tube body 1, thereby achieving the set depth of insertion of the tube body 1 into the soil.

[0028] The inner side of the tube body 1 is provided with an installation groove 7, and a retaining plate 8 is installed on the inner wall of the installation groove 7. The inside of the sliding sleeve 5 is provided with a retaining claw 9, and the outer surface of the retaining claw 9 is in contact with the retaining plate 8. The tube body 1 provides space for the retaining plate 8 through the installation groove 7. The retaining plate 8 and the retaining claw 9 each have multiple protrusions on opposite sides. Through the staggered contact between the protrusions on the retaining plate 8 and the retaining claw 9, they provide resistance to each other, thereby maintaining the stability of the sliding sleeve 5.

[0029] A lead screw 10 is rotatably connected to one side of the chuck 9. The outer surface of the lead screw 10 is threaded to the inner wall of the sliding sleeve 5. A knob 11 is connected to the end of the lead screw 10 located outside the sliding sleeve 5. The knob 11 increases the contact area between the hand and the lead screw 10, making it easier for the hand to rotate the lead screw 10. After the lead screw 10 rotates, it generates a pushing force, which provides power for the chuck 9 to move. The chuck 9 moves to contact or disengage from the chuck plate 8.

[0030] The inner side of the sliding sleeve 5 is provided with a sliding groove 12. The inner wall of the sliding groove 12 slides in contact with the outer surface of the claw 9. The sliding groove 12 supports the claw 9 and maintains the stability of the claw 9 when it moves.

[0031] There are multiple through holes 2, and the multiple through holes 2 are arranged at equal intervals. The fertilizer inside the tube 1 is released into the soil through the through holes 2, and the fertilizer is accurately released to the rhizome of Bletilla striata.

[0032] A pivot 13 is hinged to the inner wall of the funnel 4, and a cover plate 14 is connected to the outer surface of the pivot 13. A swing arm 15 is connected to one end of the pivot 13 located outside the funnel 4. The pivot 13 provides support for the cover plate 14, enabling the cover plate 14 to flip and move. The cover plate 14 flips to open the opening of the funnel 4, allowing fertilizer to be filled into the inside of the tube 1. The swing arm 15 facilitates the flipping of the cover plate 14. A sealing ring 16 is connected to the upper surface of the funnel 4, and the sealing ring 16 is made of rubber. The outer surface of the sealing ring 16 contacts the lower surface of the cover plate 14, filling the gap between the funnel 4 and the cover plate 14 to prevent moisture or foreign objects from entering the inside of the tube 1.

[0033] The lower surface of the cover plate 14 is connected to a first magnetic block 17, and the upper surface of the funnel 4 is connected to a second magnetic block 18. The first magnetic block 17 and the second magnetic block 18 are attracted by magnetic force and are attracted together by the first magnetic block 17 and the second magnetic block 18, thus maintaining the stability of the cover plate 14 and keeping the cover plate 14 in a closed position on the funnel 4 when there is no external force interference.

[0034] Working principle: First, measure the depth of the Bletilla striata rhizome in the ground. Then, move the positioning plate 6 to the appropriate depth for the Bletilla striata rhizome. Next, rotate the screw 10 by the knob 11. After the screw 10 rotates, it pushes the claw 9 to move. Then, the claw 9 contacts the plate 8, restricting the movement of the sliding sleeve 5 and the positioning plate 6, and maintaining the stability of the positioning plate 6. Then, insert the tube 1 into the soil until the positioning plate 6 contacts the ground. Open the cover plate 14 and fill the tube 1 with fertilizer. Release the fertilizer to the Bletilla striata rhizome through the through hole 2.
