Description

Technical field [0001] The invention relates to a fully automatic rice seedling throwing device. Background technique [0002] At present, paddy rice seedling cultivation is to be finished on the seedling tray, and the seedling tray has evenly distributed hole holes, and the nutrient mud and grain seeds are placed in the hole holes, and after growing into seedlings, the rice shoots on the seedling tray are pulled out (the roots of the rice shoots Bring out the nutrient mud) and throw it into the paddy field. [0003] Known rice seedling throwing method: one is that the farmers use their hands to pull out the seedlings from the seedling tray and throw them into the field. In this method of throwing seedlings, the distribution of the seedlings in the field is extremely uneven, and it is necessary to manually replant and adjust the seedlings thrown into the field. , resulting in low work efficiency and high labor intensity for farmers. Another kind is to use rice seedling thr...

AI Technical Summary

Problems solved by technology

There are several disadvantages in this rice seedling throwing device: the one is that the farmers' workload is relatively large

Because it is necessary to manually pull out the seedlings on the seedling tray and put them on the seedling transport belt, the farmers have a large workload

Second, there are many people engaged in throwing rice seedlings

The third is that when the seedling hook is working, it hooks the roots of the seedlings and hooks the seedlings out of the seedling bucket. The sharp and hard seedling hooks are easy to damage the roots of the seedlings. During work, the roots of some seedlings are damaged, and the roots are damaged. After the damaged seedlings are thrown into the paddy field, they cannot survive, and it will take a few days before the dead seedlings can be found. For the dead seedlings, it is necessary to manually replant the seedlings

The fourth is that the hook bar is working, sometimes it does not hook the seedlings, sometimes it hooks two or more rice shoots, resulting in rice shoots thrown into the paddy field, some places have no rice shoots, and some places have more than one bunch of rice shoots. Manual adjustment and replanting of seedlings are required
