Description

Technical Field

[0001] The utility model belongs to the technical field of plant seedling cultivation, and particularly relates to a chain shifting structure for unfolding a paper chain in seedling cultivation. Background Art

[0002] Vegetables are an integral part of our daily lives. They are not only delicious but also nutritious. To increase the survival rate of vegetables when growing them on a large scale, vegetable growers first raise seedlings. When the seedlings grow to 15 to 20 centimeters tall, they are transplanted.

[0003] Traditional seedling raising methods include the following: 1. Sowing seeds in a protected area to raise seedlings. This method is simple and easy to operate, but is significantly affected by environmental and weather conditions. It can also damage roots during transplanting, reducing survival rates. 2. Plug tray seedling raising. Whether for flowers or vegetables, using seed trays is a fundamental innovation in modern horticulture. This method saves seed, ensures uniform seedling emergence, prevents soil-borne diseases, and protects against root damage during transplanting, allowing for rapid seedling establishment and high survival rates. However, plug trays are typically made of materials such as polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene, which are difficult to degrade and environmentally unfriendly. 3. Paper chain seedling raising. While inheriting the advantages of plug tray seedling raising, paper chain seedling raising also offers several significant advantages: it can be used with various manual and automatic seeding machines, facilitating centralized management and improving work efficiency. The paper chains are biodegradable and environmentally friendly. Furthermore, they generally have good air permeability and drainage, promoting root growth and preventing overwatering, making them more advantageous for seedling raising. Therefore, paper chain seedling raising offers significant advantages over conventional seedling raising methods.

[0004] The process of raising vegetable seedlings using paper chains involves the following steps: ① Pull open the long paper chain, and the honeycomb-shaped seedling paper will immediately unfold. ② Secure the unfolded seedling paper in a seedling tray, allowing the tray to support the paper chain. ③ Pour culture soil into the honeycomb paper chain and spread it flat, covering it with soil once. ④ Proceed to the sowing stage. First, use a perforated tray to press holes in the covered nutrient soil. Then pour the seeds into a double-layer sowing tray for screening, ensuring that there are seeds in every hole in the lower layer. Finally, push the seeding sheet on the bottom layer out of place and drop the seeds. ⑤ Cover the soil again and wait for the seeds to germinate.

[0005] While paper chain seedling cultivation offers significant advantages over other seedling cultivation methods, its operation currently relies entirely on manual labor, which is time-consuming and labor-intensive for large-scale planting. Three key issues stand out: labor costs are high, at approximately 500 yuan per acre; individual differences in labor lead to varying seedling quality, resulting in poor quality; and it takes 25 hours of manual labor to cultivate the seeds per acre, resulting in extremely low planting efficiency. Therefore, to effectively improve the efficiency of paper chain seedling cultivation and save costs, a fully automatic, efficient, economical, and environmentally friendly vegetable seedling raising machine holds great promise.

[0006] The commonly used paper pot shape, also known as a paper chain, has a regular hexagonal cross-section, with the cross-sectional dimensions determined by the crop variety. Paper chains are primarily made from wood pulp and straw fibers, processed using a special formula to create specialized paper chain seedling paper. Individual paper chains are then mechanically assembled and assembled into bundles.

[0007] Manual paper chain seedling cultivation, which requires manual unrolling of paper chains, has long been a common method for raising vegetable and flower seedlings. This process consumes significant labor, increasing breeding costs. In an era of rising labor costs and rapid mechanization, combining paper chains with automated machinery is needed to free farmers' hands and address the research gap in seedling machinery both domestically and internationally. Existing equipment often damages the paper chain due to its large expansion range and rapid speed. Incomplete unrolling compromises its usability and subsequent breeding efforts.
