[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, a sweet potato seedling covering device comprises: a driving mechanism and a covering mechanism arranged on a frame 1, the driving mechanism comprising: a driving shaft 2 arranged at the front end of the frame 1, front wheels 3 symmetrically arranged at both ends of the driving shaft 2, the front wheels 3 connected to the driving shaft 2 through a positioning sleeve 5, a driving device 20 is arranged on the top of the frame 1, and an internal combustion engine is preferably used as the driving device 20, a first pulley is arranged at the output end of the driving device 20, a second pulley is arranged in the middle part of the driving shaft 2, the first pulley and the second pulley are connected through a transmission belt 21, a strip slide groove 15 is arranged on the outer peripheral side of the driving shaft 2, pre-tightening bolts are arranged at both ends of the positioning sleeve 5, the pre-tightening bolts and the strip slide groove 15 cooperate with each other, and the spacing between the two front wheels 3 is changed by adjusting the positions of the two positioning sleeves 5 on the driving shaft 2.

[0024] like Figure 2 and Figure 3As shown, the film covering mechanism includes: a first mounting tube 6 arranged in the middle of the frame 1, a first fixed tube 7 symmetrically arranged at both ends of the first mounting tube 6, a fixed rod 8 arranged at the bottom of the first fixed tube 7, a rotating rod 9 arranged in the middle of the fixed rod 8, a ground film rolling roller 10 arranged on the rotating rod 9, an assembly rod 12 arranged on one side of the fixed rod 8, a guide roller 16 arranged on one side of the assembly rod 12, a first soil-cutting plate 13 arranged at the bottom of the fixed rod 8, a second mounting tube 17 arranged at the rear end of the frame 1, a second fixed tube 18 symmetrically arranged at both ends of the second mounting tube 17, a rear wheel 19 arranged at the bottom of the second fixed tube 18, a support rod arranged outside the rear wheel 19, and a second soil-cutting plate 14 arranged at the bottom of the support rod. The positions of the first fixed tube 7 and the second fixed tube 18 are adjusted so that the spacing between the two front wheels 3 and the spacing between the two rear wheels 19 can be flexibly adjusted according to the distance between two adjacent ridges, so as to adapt to ground film rolling rollers 10 of different widths, avoid the excessive spacing between the two front wheels 3 and the two rear wheels 19 from scratching and damaging the adjacent ground film 11, and achieve better film covering effect.

[0025] In a preferred embodiment of the utility model, the distance between the two front wheels 3 is greater than the distance between the two rear wheels 19, and the rear wheels 19 press the top surface of the ground film 11, and the distance between the two first soil-cutting plates 13 is less than the distance between the two second soil-cutting plates 14. The first soil-cutting plates 13 and the second soil-cutting plates 14 on the same side of the frame 1 are arranged in opposite directions. The first soil-cutting plates 13 are used for trenching and turning the soil to the outside of the first soil-cutting plates 13. After the ground film 11 is laid on the bottom surface, the rear wheels 19 will first press the ground film 11 in the trench, and the second soil-cutting plates 14 will turn the soil on the outside of the first soil-cutting plates 13 to the upper surface of the edge of the ground film 11 to compact the ground film 11 while trenching, thereby effectively improving the soil turning and covering effect of the ground film 11 and ensuring that the ground film 11 is stably compacted.

[0026] In a preferred embodiment of the utility model, since the ridge has a certain inclination angle, the guide roller 16 is inclined, and the outer peripheral side of the guide roller 16 is in contact with the upper surface of the ground film 11, so that the ground film 11 is better covered on the surface of the ridge. On the other hand, a plurality of scraping plates 4 are arranged in an array on the outer peripheral side of the front wheel 3 to effectively prevent the front wheel 3 from slipping during travel.

[0027] The working principle of the utility model is as follows: according to the distance between two adjacent ridges, the positions of the two positioning sleeves 5 on the driving shaft 2 are adjusted to change the spacing between the two front wheels 3, the positioning sleeves 5 are locked by the pre-tightening bolts, and the positions of the first fixing cylinder 7 and the second fixing cylinder 18 are adjusted at the same time to adjust the spacing between the two rear wheels 19. The ground film roller 10 is installed on the rotating rod 9, and the driving device 20 is started. The driving device 20 drives the driving shaft 2 to rotate through the transmission belt 21, and the driving shaft 2 drives the front wheel 3 to rotate, thereby driving the entire device to move forward along the ridge furrow. The ground film roller 10 continuously unwinds the ground film 11, and the first soil-cutting plate 13 is used to make furrows and turn the soil to the outside of the first soil-cutting plate 13. After the ground film 11 is laid on the bottom surface, the rear wheel 19 will first press the ground film 11 into the furrow, and the second soil-cutting plate 14, while making furrows, turns the soil on the outside of the first soil-cutting plate 13 to the upper surface of the edge of the ground film 11 to compact the ground film 11 until the laying of the ground film 11 is completed.

[0028] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
