[0019] See also Figures 1 to 3 , this embodiment provides a rotary mud film covering device, including a power mechanism and a film covering mechanism.

[0020] The power mechanism adopts the power device of the handheld electric punch, including a gasoline engine 1, a handheld rod 2, a flexible shaft 3 and a transmission component. The transmission component is installed in the handheld rod 2. The gasoline engine 1 is connected to one end of the transmission component through the flexible shaft 3. The gasoline engine 1 drives the flexible shaft 3 to rotate, thereby driving the rotation of the transmission component. The transmission component can be a transmission shaft. The handheld electric punch is a commonly used instrument in tobacco transplanting and drilling. It is composed of the aforementioned power mechanism and a drilling bit. The drilling bit is installed on the transmission component at the end of the handheld rod 2. The gasoline engine 1 drives the flexible shaft 3, the transmission component and the drilling bit to rotate, thereby realizing rotary drilling.

[0021] The film covering mechanism comprises a housing 4, a worm gear mechanism, a rotary tiller 6, a mud guide plate 7 and a film pressing wheel 8. The housing 4 is mounted at the end of the hand-held rod 2, and the worm gear mechanism is mounted in the housing 4, and the housing 4 is T-shaped. The worm gear mechanism comprises a worm, a worm wheel and a rotating shaft 5, wherein the worm is used to be connected to the other end of the transmission component, the rotating shaft 5 is fixed on the worm wheel and can rotate with the worm wheel, the two ends of the rotating shaft 5 extend to the two sides of the hand-held rod 2, and the rotary tiller 6 is mounted at the two ends of the rotating shaft 5. The number of soil blades can be determined according to actual conditions, for example, it can be three or four. A base plate 73 is installed on the top of the shell 4, and the mud guide plate 7 includes a vertical plate portion 71 and a horizontal plate portion 72. The vertical plate portion 71 is connected to the base plate 73, and the horizontal plate portion 72 is connected to the top of the vertical plate portion 71, so as to cover the rotary blade 6. The front and rear sections of the vertical plate portion 71 gradually bend outward, and the horizontal plate portion 72 is in an arc shape. The part of the horizontal plate portion 72 located above the rotary blade 6 is at the highest point, and the part located on the outside of the rotary blade 6 is bent downward to the middle and upper part of the rotary blade 6, so that the horizontal plate portion 72 can guide the soil rotated by the rotary blade 6 to its outside, and under the obstruction of the arc-shaped horizontal plate portion 72, most of it will fall on the outside of the rotary blade 6, and the mud splashed front and back will also fall on the front and rear positions of the outside of the rotary blade 6 under the guiding action of the vertical plate portion 71. The front and rear parts of the mud guide plate 7 are provided with a film pressing wheel 8 that can move up and down elastically at a certain distance from the rotary tiller 6. The film pressing wheel 8 is pressed on the ground film during operation to prevent the ground film from being opened, thereby improving the film covering effect. At the same time, due to its elasticity, it will not affect the soil turning effect of the rotary tiller 6. Specifically, the front and rear sections of the transverse plate portion 72 are provided with an adjustment rod 9, and the film pressing wheel 8 is adjustably installed on the adjustment rod 9 through a support rod 10. The support rod 10 includes an upper support rod 101, a lower support rod 102 and a spring 103. The upper support rod 101 is movably sleeved outside the lower support rod 102, and the two ends of the spring 103 are respectively connected to the upper support rod 101 and the lower support rod 102.

[0023] First, the device is placed in the furrow, the rotary tiller 6 is close to the ground film, the film pressing wheel 8 is adjusted to press the edge of the ground film on both sides, and then the gasoline engine 1 is started. The gasoline engine 1 drives the transmission component to rotate through the flexible shaft 3, and then drives the worm gear mechanism to drive the rotary tiller 6 to roll forward. The rotary tiller 6 can rotate the soil, and under the action of the mud guide plate 7, the rotated soil can be guided to the ground film on both sides, thereby improving the quality of the film covering. Compared with the prior art, the utility model can press the ground film to prevent it from being lifted when the rotary tiller 6 rotates the soil by installing an elastic film pressing wheel 8 on the existing rotary tillage mud guide film covering device, thereby improving the film covering effect. In addition, the utility model designs the front and rear sections of the vertical plate portion 71 to gradually bend outward, and the portion of the transverse plate portion 72 located on the outside of the rotary blade 6 is designed to bend downward to the middle and upper part of the rotary blade 6, so that the transverse plate portion 72 can guide the soil turned up by the rotary blade 6 to the outside thereof, and most of the soil will fall on the outside of the rotary blade 6 under the obstruction of the arc-shaped transverse plate portion 72, and the soil splashed forward and backward will also fall on the front and rear positions of the outside of the rotary blade 6 under the guidance of the vertical plate portion 71, and most of the soil will fall on the ground film, thereby improving the film covering effect.
