Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0056] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0057] The planting device 1 of the utility model comprises a soil covering component 5, such as Figure 3 , 5Aand 5B, comprising a mounting frame 61, a fourth linear drive 53 and a covering plate 55, wherein outer brackets 613 are respectively arranged on both sides of the mounting frame 61, the fourth linear drive 53 is arranged on the outer bracket 613 inwardly inclined, and the driving end of the fourth linear drive 53 is connected to the covering plate 55; the output ends of the two fourth linear drives (53) on both sides are respectively inclined toward the lower side of the mounting frame 61, and the upper side of the covering plate 55 is arranged horizontally.

[0058] Under the inclined push of the fourth linear drive 53 and the covering plate 55, the sand or soft soil makes a compound movement toward the tree hole and downward, so that the sand is squeezed toward the tree roots and the floating sand or floating soil is pushed into the tree pit, thereby stabilizing the roots of the saplings in the tree pit.

[0059] The horizontal angle of the fourth linear drive 53 is 45-70 degrees, preferably 50-60 degrees.

[0060] like Figure 5A and 5B The driving end of the fourth linear actuator 53 is connected to the soil covering plate 55 through the second connecting member 54, and an arc-shaped scraper 56 is provided on the lower side of the soil covering plate 55. The soil is scraped toward the tree pit by the scraper 56.
