Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to an automatic transplanting machine for the traditional Chinese medicine Salvia miltiorrhiza. Background Technology

[0002] In agricultural planting, especially for the cultivation of the traditional Chinese medicinal herb Salvia miltiorrhiza, transplanting is a crucial step in ensuring crop growth quality and yield. Traditional Salvia miltiorrhiza transplanting relies primarily on manual labor, which is not only labor-intensive and inefficient but also makes it difficult to guarantee the uniformity and survival rate of transplanted seedlings, severely hindering the large-scale and modern development of the Salvia miltiorrhiza planting industry. Currently, Salvia miltiorrhiza cultivation in Shaanxi Province mainly adopts a three-row staggered transplanting pattern. The design of existing transplanting equipment's seedling placement mechanism cannot meet the requirements of this agronomical method. Furthermore, due to continuous manual seedling placement, operator negligence and fatigue are inevitable, leading to problems such as missed or overlapping seedlings.

[0003] Chinese Patent No. CN201878525U discloses a seedling feeding device for a transplanter, including a support base, a central cylinder, a horizontal fixing plate, a feeding cup rotating shaft, a feeding turntable, a feeding cup, a transmission device, a guide rail device, and a cup door device. The front of the horizontal fixing plate has a feeding opening and is equipped with a guide rail device. The feeding cup rotating shaft is installed inside the central cylinder. A feeding turntable that can rotate around the central cylinder with the feeding cup rotating shaft is fixedly installed on the upper part of the feeding cup rotating shaft. At least one feeding cup is fixedly installed on the feeding turntable. Each feeding cup has a cup door device that can be opened by the guide rail device at its lower part.

[0004] However, the above-mentioned transplanter seedling feeding device has the following drawbacks: the setting and distribution of the seedling feeding cups cannot adapt to the planting pattern of three rows of alternating transplanting in one ridge, resulting in uneven seedling feeding and failing to meet the agronomic requirements of Salvia miltiorrhiza planting; during the seedling feeding process, the opening and closing of the cup door device is not flexible and accurate enough, which easily leads to seedling jamming, affecting the smoothness and efficiency of seedling feeding. Summary of the Invention

[0005] To address the shortcomings of existing technologies and in response to the requirements of Salvia miltiorrhiza transplanting agronomy and mechanized transplanting in Shaanxi Province, this utility model provides a three-row seedling turntable for Salvia miltiorrhiza transplanting. This turntable allows one person to simultaneously place seedlings and transplant three rows of Salvia miltiorrhiza into the turntable, making it suitable for the planting agronomy of three rows per ridge for Salvia miltiorrhiza transplanting in Shaanxi Province. This reduces labor consumption and improves transplanting efficiency.
