Description

Technical Field

[0001] This utility model relates to the field of evening primrose seeders, and particularly to a detachable evening primrose seeder. Background Technology

[0002] Evening primrose: A biennial herbaceous plant belonging to the genus *Oenothera* of the family Onagraceae. It can grow to 1-1.5 meters tall, with an erect stem. The basal leaves are oblanceolate, while the stem leaves are lanceolate. The flowers are large, yellow, and open in the evening, emitting a fragrance. Flowering occurs from June to September. It prefers sunny, well-drained sandy loam soil, is drought-tolerant, cold-hardy, and highly adaptable. It has ornamental value (beautiful flowers, suitable for gardens and flower borders), medicinal value (the seeds contain gamma-linolenic acid, which can regulate endocrine function and improve skin texture), and ecological value (attracting pollinating insects).

[0003] Seeder: A tool used for precise sowing of evening primrose seeds, available in manual and automatic types. Manual seeders (such as handheld funnel type or hand-push roller type) are suitable for small-area planting, with a simple structure. The sowing amount (single seed or small amount) is controlled by adjusting the settings, and the sowing depth can be set to 0.5-1 cm (to avoid affecting germination due to the small size of the seeds). Automatic seeders (electric or mechanically driven) are suitable for large-area planting, offering high efficiency and simultaneously completing furrowing, sowing, and covering with soil. When using an automatic seeder, first select plump seeds, prepare a loose and level seedbed, adjust the seeder parameters according to the seed size, lightly cover with a thin layer of soil after sowing, and water to retain moisture. Note the sowing time (spring sowing March-April or autumn sowing September-October), keep the soil moist after sowing, and clean the seeder after use to avoid seed residue clogging.

[0004] Evening primrose seeders are prone to clogging of the seed dispensing channel due to seed residue, accumulated impurities (such as soil and debris), and the characteristics of evening primrose seeds (uneven size, surface fuzz / sticky substances). This results in uneven seeding, missed sowing, reduced sowing efficiency and quality, and in severe cases, damage to components. Cleaning requires disassembling the mechanism, which has a complex structure involving multiple connectors (screws, clips). Disassembly requires specialized tools, is difficult for non-professionals, and is time-consuming, affecting agricultural progress. Frequent disassembly can cause wear and loosening of components, and improper reassembly may cause secondary blockages or malfunctions. The overall cleaning process is tedious and inconvenient.

[0014] like Figure 1 - Figure 5 As shown, the detachable evening primrose seeder includes a storage box 1 and a compartment 2. The upper end of the storage box 1 has a compartment 2, which is used to store evening primrose seeds. The top of the compartment 2 is equipped with an openable and closable sealing cover, which facilitates the addition and sealing of seeds and prevents moisture and impurities from entering. The storage box 1 has quick-release seats 3 welded to both sides of its lower end, and a U-shaped support frame 4 is detachably connected to the quick-release seats 3. Multiple mounting brackets 13 are bolted to the lower end of the U-shaped support frame 4. Each mounting bracket 13 is connected to a plow head 11 and a side plate 12 at its lower end. The plow head 11 is made of wear-resistant alloy material, and the side plate 12 has an arc-shaped structure. The plow head 11 breaks the soil, and the side plate 12 shapes the trench, thus achieving stable and continuous trenching operations. One side of the U-shaped support frame 4 is connected to an air outlet fan 6 via a mounting base 5. The outlet of the air outlet fan 6 is connected to a main pipe 9. The side wall of the storage box 1 is equipped with a quick-release connector 7. The lower end of the quick-release connector 7 is connected to a docking seeding pipe 8 via a clamp. The lower outlet of the docking seeding pipe 8 is precisely positioned behind the plow head 11, in the gap between the plow head 11 and the side plate 12, for the purpose of achieving fixed-point sowing of Kapok seeds. The docking seeding pipe 8 is connected to the main pipe 9 by a branch hose 10. The airflow generated by the exhaust fan 6 is transported to the docking seeding pipe 8 through the main pipe 9 and the branch hose 10, forming a directional airflow to assist seed discharge and effectively prevent seeds from getting stuck or blocked in the pipe. The quick-release base 3 includes a base body and quick-release bolts. The quick-release bolts are symmetrically arranged at both ends of the base body. Their specifications are M6 and M8, which meet the requirements of high-strength assembly. The quick-release base 3 achieves quick locking connection with the protrusion reserved at the lower end of the storage box 1 and the mounting hole at the upper end of the U-shaped support frame 4 through the quick-release bolts. The front view of the U-shaped support frame 4 is a "U" shaped structure, made of cold-rolled steel plate, which has high structural strength and resistance to deformation. The U-shaped support frame 4 and the mounting base 5 are fastened together by four sets of bolts. Anti-slip buffer pads are added between the connecting surfaces, which can increase friction, prevent displacement, and reduce the impact of operation vibration. The exhaust fan 6 is bolted to the mounting base 5. Its exhaust port is a circular tubular structure with a standard flange at the port. The main pipe 9 is connected to the exhaust fan 6 through this flange, and a pressure-resistant sealing ring is embedded at the connection to ensure the air circuit is sealed. The branch hose 10 is fixed to the corresponding interface of the main pipe 9 by heat fusion process. The main pipe 9 body is fastened to the inside of the U-shaped support frame 4 by clamps to keep the pipeline neat and free from external interference. The branch hose 10 is connected to the docking seeding pipe 8 by flanges and bolts. The connection port is also equipped with a sealing ring to prevent air leakage from affecting the stability of the seeding airflow. The branch hose 10 is bent in a "C" shape and has a certain degree of flexibility, which can adapt to small-amplitude position adjustments and vibration shifts. The butt-joint seeding pipe 8 and the quick-release connector 7 are connected by a compression seal through a stainless steel clamp. The connecting section is embedded with a rubber sealing ring to further improve the sealing performance. The lower end of the butt-joint seeding pipe 8 extends to the gap between the plow head 11 and the side plate 12 to ensure that the seeds can fall accurately into the prepared seed furrow and complete the seeding process.

[0015] Storage box 1 is connected to U-shaped support frame 4: The quick-release bolts (M6, M8) on quick-release seat 3 are used to lock the storage box 1 to the pre-drilled protrusion at the lower end and the U-shaped support frame 4 to the mounting holes at the upper end, achieving a quick connection. Mounting bracket 13, plow head 11, and side plate 12 are installed: Multiple mounting brackets 13 are bolted to the lower end of the U-shaped support frame 4, with each mounting bracket 13 connected to the plow head 11 and side plate 12 at its lower end. Mounting seat 5 is connected to U-shaped support frame 4: U-shaped support frame 4 and mounting seat 5 are fastened with four sets of bolts, and anti-slip buffer pads are added to the connection surface. The exhaust fan 6 is bolted to mounting seat 5, and its standard flange for the circular tubular exhaust port is connected to the main pipe 9, with a pressure-resistant sealing ring embedded at the connection. After the main pipe 9 is connected to the exhaust fan 6 via the flange, it is secured to the inside of the U-shaped support frame 4 with clamps. The branch hose 10 is fixed to the corresponding interface of the main pipe 9 using a heat-fusion process, forming a "C"-shaped bend. The branch hose 10 is connected to the docking seeding pipe 8 via flanges and bolts, with a sealing ring at the port. The upper end of the docking seeding pipe 8 is connected to the quick-release connector 7 (side wall of storage box 1) via a stainless steel clamp, with a rubber sealing ring embedded in the connecting section, and the lower outlet extends to the gap between the plow head 11 and the side plate 12. The top of the box 2 is covered with an openable and closable sealing cover.

[0016] Open the sealed cover of chamber 2, place the evening primrose seeds into chamber 2, and tighten the sealed cover to prevent moisture and impurities from entering. Start the exhaust fan 6; the airflow is delivered through the main pipe 9 and branch hoses 10 to the docking seeding pipe 8, forming a directional assisted seed discharge airflow. As the equipment moves, the plow head 11 breaks up the soil, and the side plate 12 shapes the furrow, working together to form a stable seed furrow. The seeds enter the docking seeding pipe 8 from chamber 2 through the quick-release connector 7, and with the assistance of the airflow, they fall precisely into the seed furrow from its lower outlet (located behind the plow head 11, in the gap between the plow head 11 and the side plate 12), completing the sowing.
