The transmission ratio of the steering gear 21 to the film laying auxiliary gear shaft 20 is 1:2.

[0077] Embodiment 2

[0078] In this embodiment, a specific use method of the ridging and film covering device is also provided. When the ridging and film covering device is used, the hand wheel 32 is adjusted according to the width of the ground film used, so that the rotation of the gear drives the worm 7 to rotate, so that the worm wheel 8 moves left and right on the crossbeam 24, and the movement of the worm wheel 8 drives the film storage device 2 to move left and right through the column 14 and the sliding buckle 29 so that the width conforms to the width of the ground film. Since the mold changing mechanism 6 uses a connecting rod 18, the connecting rod is a parallel four-bar mechanism, which is connected to the load-bearing crossbeam 19, and there is a "T"-shaped groove in the load-bearing crossbeam 19. There is a spring in the groove. When the film storage device 2 moves, the spring is forced to push the parallel four-bar to move, ensuring that the relative position of the film changing mechanism remains unchanged. In the worm gear, the worm wheel 8 cannot drive the worm 7 to rotate, thereby realizing the self-locking of the mechanism. Put all the required amount of ground film into the film storage device 2. Under the action of gravity, the ground film will roll to the film changing wheel 3. There is a designed groove in the film changing wheel 3. When the film changing wheel 3 is in the state of receiving the ground film, the ground film will enter the film changing wheel 3 due to gravity, and then the film changing wheel 3 will rotate to the normal working position. When a roll of ground film is used up, the film changing wheel 3 will continue to rotate and pass through the stick storage device 5. At this time, the used ground film enters the stick storage device 5 under the action of gravity. The stick storage device 5 is composed of 4 stick storage chambers. A certain slope is provided at the connection between each film storage chamber and the next film storage chamber, so that when one stick storage chamber is full, the central stick supporting the ground film can automatically enter the next stick storage chamber until it is full. When the film-changing wheel 3 is in the working position, the film-changing mechanism 6 starts to work first, and the cam 1-1 rotates to drive the rocker 1-2 and the long rocker 1-3 to swing. The swing of the long rocker 1-3 causes the piston 1-7 to move in the pressure transmitter 1-8, and the pressure oil in the pressure transmitter 1-8 is compressed. The pressure increase drives the driven rack 1-5 to move linearly. The movement of the driven rack 1-5 causes the film-absorbing rod gear 1-4 to rotate, and the long rocker 1-3 swings through the key connection and stays at the position of the film for a period of time, during which the suction cup 1-9 absorbs the film. After the film is absorbed, the cam 1-1 continues to rotate and stays for a period of time when the long rocker hits the limit plate 6. At this time, the film will be tightened by the film pressing rod 15 and transported to the holding mechanism 10. After the clamping mechanism 10 is clamped, the driving motor of the slider 9 drives the clamping mechanism 10 and the steering gear 21 to move in the groove of the film-laying column 27. The steering gear 21 first contacts the auxiliary film laying gear shaft 20, with a transmission ratio of 1:2. Due to the existence of the steering gear 21, the clamping mechanism 10 will not collide with the auxiliary film laying rod 11 and the film covering rod 12 on the auxiliary film laying gear shaft 20. When the slider completes a circle, the film laying is completed. When the work reaches the end of the field, the ground film is cut by the film cutting mechanism 23. Automatic film cutting and automatic replacement of ground film are realized, which reduces manual operations and further improves the efficiency of ground film laying.
