Description

Technical Field

[0001] The invention relates to the technical field of tobacco seedling film breaking and soil sealing machinery, and in particular to a film breaking, seedling digging and soil sealing device. Background Art

[0002] In the early stage of tobacco seedling planting, mulching technology is often used. Mulching can increase the ground temperature of tobacco fields, retain soil moisture, and inhibit the growth of weeds. It can promote the early growth of tobacco, reduce nutrient loss in tobacco fields, and reduce the damage of weeds and pests. However, the root system of tobacco plants in tobacco fields covered with mulch is shallow, and the drought resistance is poor. The tobacco plants are prone to premature aging in the later stage of growth. Therefore, after the mulch has been covered for a certain period of time, it is necessary to release the seedlings and surround the soil in time, that is, the film should be broken just above the tobacco seedlings to leak out the tobacco seedlings, and then the soil should be surrounded at the roots of the tobacco seedlings. The general time for releasing the seedlings is from the time when the tobacco plants enter the tray to the group stage (under normal circumstances, 30-35 days after transplanting). At present, when tobacco farmers plant tobacco seedlings, due to the lack of professional tools, they often need at least two people to squat on both sides of the ridges between the rows of tobacco plants. One person uses two hands to gather the tobacco leaves from both sides of the tobacco seedlings upward and fix them, that is, to gather the horizontally spread tobacco leaves into a vertical upward state. The other person breaks a hole of appropriate size in the mulch film under the tobacco seedlings, and then uses the soil in the ridges between the rows of tobacco plants to cover the stem base of the lower part of the tobacco seedlings, which is conducive to the formation of a more developed root system of the tobacco plants, and is convenient for irrigation and fertilization, etc., creating a good environment for the early growth of tobacco plants. However, since all operations are manually performed, and because the height of the tobacco plants is relatively low, manual squatting is required for operation, and the tobacco field planting area is large, the labor intensity is high, and the operation efficiency is low. Summary of the invention
