Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, in particular to a tobacco planting seedling raising device. Background Art

[0002] In the agricultural field, tobacco, as an important economic crop, has always received widespread attention for its planting and seedling cultivation technology. Although existing seedling cultivation devices can replenish the seedlings with fluid when in use, they require manual mixing of the nutrient solution with water during the replenishment process, which increases the workers' operating steps and thus increases their working time. In addition, when the nutrient solution is stored for a long time, stratification may occur, affecting the effectiveness of the nutrient solution.

[0003] A Chinese patent discloses a tobacco planting and seedling raising device (authorization announcement number CN220108751U). This patented technology uses a stirring tank, a sealing plate, a driving motor, a rotating rod, a stirring shaft and a drainage pipe in combination. When infusing tobacco seedlings, workers only need to put water and nutrients into the stirring tank together, which can reduce the time and labor intensity of manually mixing nutrients. Moreover, when the nutrient solution inside the stirring tank is stored for a long time, stratification will occur inside. When in use, the nutrient solution inside can be mixed again by rotating the rotating rod and the stirring shaft, thereby improving the practicality of the device. Furthermore, by using the mounting plate, the planting box, the movable plate and the collection box in combination, the excess nutrient solution can be discharged when the tobacco is infused, avoiding the situation of excessive nutrient solution. After discharge, the nutrient solution can also be collected through the collection box for subsequent reuse.

[0004] However, it has certain disadvantages: it collects excess nutrient solution through a collection box, and the nutrient solution flows down after passing through the tobacco seedlings and soil, which will be mixed with a lot of dust and impurities. It is unable to filter the dust and impurities mixed in the nutrient solution, and requires manual filtration later, which is more troublesome. Utility Model Content
