Description

Technical Field

[0001] The utility model relates to the technical field of pit digging devices, in particular to a pit digging device for navel orange cultivation. Background Art

[0002] Navel oranges are rich in nutrients, containing a large amount of vitamin C and carotene, which helps inhibit the formation of carcinogens. They can also soften and protect blood vessels to promote blood circulation, help lower cholesterol and blood lipids, reduce the possibility of heart disease, and prevent gallbladder disease. Navel oranges are best eaten fresh, but fresh fruits can also be squeezed into juice. Navel oranges have a large number of flowers, and their flowers can be smoked to make rue tea; essential oils can be extracted from the peel, leaves and young branches. Navel oranges and peaches can be used to make wine, which is often used as gifts for relatives and friends.

[0003] The main method of propagation of navel oranges is grafting. After the rootstock is grafted, it needs to be buried in the soil for cultivation. Workers are required to dig holes and bury them, which is time-consuming and laborious. The existing large-scale pit-digging equipment on the market is too expensive, and small and medium-sized pit-digging equipment also requires repeated bending. Long-term and repeated bending will cause lumbar muscle strain for workers. For this reason, we have developed a pit-digging device for navel orange cultivation. Utility Model Content
