Finally, the film pressing roller 303 continuously provides ground film, and under the action of the soil covering and film pressing mechanism 301, the ground film is covered on the ridge, and the soil is covered on both sides of the laid ground film, that is, when the ground film is laid on the ridge, the film pressing wheel 3013 located below presses on the ground film, the soil covering knife 3012 covers the soil on the ground film, the film pressing rod 304 presses on both sides of the ground film, and the film pressing roller 303 presses on the middle position of the ground film, so that the ground film is unfolded and the film is continuously fed.

[0040] The utility model drives two spline sleeves 203 and the knife shaft tube 205 to rotate simultaneously by setting the output shaft of the rear transmission box 202, so that the inner blade and the outer blade on the ground break the soil and then turn the ground, so as to realize ridge formation after rotary tillage of the ground, and ensure that the ridge furrow is flat after ridge formation; the film pressing roller 303 is provided to provide the ground film, and under the action of the soil covering and film pressing mechanism 301, the ground film is covered on the ridge furrow, and the soil is smoothly covered on both sides of the laid ground film; by setting the traction device 1, when the driving motor works, it drives the driving wheel 1024 thereon to work, and the crawler 1026 moves forward with it, and the guide wheel 1022, The upper support wheel 1025 and the lower support wheel 1023 rotate accordingly to guide the walking direction and support the crawler track 1026 to ensure the stable walking of the walking mechanism 102; by setting the lower support wheel 1023 on the lower right side of the guide wheel 1022, the guide wheel 1022 is located at the front, forming a pointed structure to reduce resistance and facilitate smooth progress; through the transmission mechanism 103 set on the frame 101, when the front transmission box 1031 is working, while ensuring the smooth operation of the driver, the power is transmitted to the front universal joint outer fork, and the power is transmitted to the sliding universal joint fork through the front cross shaft 1032, the sliding universal joint fork 1032 can rotate around the front cross axis to reduce the transmitted torque and ensure smooth transmission of power; the setting of the sliding universal joint fork 1032 and the rear universal joint outer fork 1034 can adjust the position between the two to meet the working needs; through the two parallel lower suspension arms set at the rear end of the frame 101 and the crank arm seat installed at the upper end, the ridging cover bracket 201 and the frame 101 are connected by three points to ensure a stable connection; by setting an angle between the inner knife seat and the outer knife seat 206, the angle is an obtuse angle to ensure that the impact is reduced when breaking the soil. force, protecting the blade and making it easy to enter the soil; by setting the film pressing wheel 3013 and the soil covering knife 3012, and setting the two soil covering knives 3012 correspondingly and tilting the rear ends toward each other, so as to cover the soil on the ground film; by setting the ground film roller 305, to provide the ground film; by setting the film pressing roller 303 between the two film pressing wheels 3013 and the film pressing rod 304 located on both sides of the film pressing roller 303 and bending downward, so as to smoothly flatten the ground film; by setting the limit column on the support arm 3011 and being able to abut on the ridging cover support 201, the downward movement distance of the support arm 3011 can be limited. The utility model can ensure that the soil surface on the ridge ditch is flat after ridging and the film is flattened during film covering, thereby improving the efficiency of ridging and film covering.
