TECHNICAL FIELD
[0001] The present application relates to the technical field of agricultural transplanting machinery, in particular to a pepper pot seedling taking device. BACKGROUND
[0002] Pepper is an important economic crop and is widely planted worldwide. Its production efficiency and quality are directly related to farmers' income and market supply. Traditional pepper planting relies on manual seedling and transplanting, which is labor-intensive and inefficient, making it difficult to meet the development needs of modern agricultural scale and mechanization. With the advancement of agricultural technology, pot seedling transplanting technology has emerged. This technology cultivates healthy and robust seedlings in advance under greenhouse or protected land conditions, and then transplants these seedlings together with nutrient soil blocks (i.e., pot seedlings) to the field. This not only improves seedling survival rate but also promotes early growth, enabling crops to enter the fruiting stage more quickly, thereby achieving the purpose of increasing yield and income. In addition, pot seedling transplanting can effectively prevent soil-borne diseases and reduce pesticide use, which is beneficial to environmental protection and agricultural product safety. However, existing pot seedling taking equipment has problems such as unstable taking and low efficiency in actual application, which limits the further promotion of pot seedling transplanting technology.
[0003] In the prior art, patent CN 222337064 U provides a mechanism for taking seedlings through a three-axis mechanism. In this mechanism, the three axes cooperate to move for seedling taking operation, which is very low in efficiency. Therefore, many schemes use multiple clamping jaws to take seedlings in a row. However, the efficiency of translation is still low when taking seedlings in a row. Therefore, in some schemes, all clamping jaws are installed on a cantilever beam rotating arm. However, the structure of the rotating arm has the problems of poor stability and uneven force on the pepper seedlings grabbed by each seedling taking clamping jaw. The farther the clamping jaw is from the center of rotation, the greater the centrifugal force it receives, which can easily throw away the pepper seedlings or cause damage to the seedlings. SUMMARY
