Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic seedling soil filling device. Background Art

[0002] Container seedling cultivation technology has been widely used in forestry, agriculture, and other fields due to its advantages, such as improving the survival rate of transplanted seedlings and facilitating transportation and management. As the scale of container seedling cultivation continues to expand, automatic seedling soil filling technology, a key link in agricultural production, has placed higher demands on the efficiency and quality of seedling soil filling.

[0003] In the related technology, after searching, it was found that a solution of a nutrient pot soil filling device (publication number CN107593171A) includes a soil crushing part, a soil conveying part, a soil filling part, a nutrient pot transportation part, and a control part, realizing an integrated device for crushing soil, conveying soil, filling soil and transporting nutrient pots.

[0004] There is also a solution for a nutrient soil degassing and potting machine (publication number CN110720331A). Through the setting of a filter mechanism, a crushing mechanism and a stirring element, it will effectively prevent foreign matter such as stones in the nutrient soil, and can fully diffuse the nutrient soil through crushing and stirring. When the material inside the storage hole is full, the limit detector detects it in time, thereby sending a signal to the wireless signal transceiver, and the wireless signal transceiver then sends a signal to the switch, and the switch closes the discharge port.

[0005] The above two schemes can both achieve the functions of crushing, transporting and loading soil. However, after the nutrient pots are filled with soil, they need to be sown. The above schemes all require manual labor or additional equipment to sow in the nutrient pots. There are deficiencies in the degree of connection between container seedlings. In large-scale seedling production, after loading the soil, it is necessary to wait for manual labor or equipment to complete sowing, which reduces the seedling yield. The nutrient pots may also be overturned during the connection process of the nutrient pots. Summary of the Invention
