Description

Technical Field

[0001] The utility model belongs to the technical field of land planting, and specifically relates to a ground film covering device. Background Art

[0002] Film covering is usually the process of recycling the plastic film covering the soil surface. When the crops are cleared, the waste film needs to be recycled in time to facilitate the subsequent tillage and planting of the soil. By covering the soil surface with film, it can keep the soil warm, moisturize it, and inhibit the growth of weeds. It is a commonly used method in modern planting.

[0003] Many of the existing mulch film collecting devices utilize a winding roller for winding. The winding roller is connected to a tractor and moves with the tractor to achieve the recovery of the waste mulch film. However, this type of mulch film collecting method often relies on the pulling force of the winding roller to pull the mulch film out of the soil, and the mulch film is often torn. Therefore, the continuity of the mulch film collecting operation is affected, and the mulch film cannot be recovered continuously and effectively. Utility Model Content

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-Figure 5 As shown, a ground film covering device comprises a support frame 1, a connecting frame 2 is movably connected to the side wall of the support frame 1, three film turning components are installed near the right side of the bottom of the support frame 1, two rotating shafts 9 are connected to the bottom of the support frame 1 for symmetrical rotation front and back, a movable wheel 8 is fixedly connected to the side wall of the rotating shaft 9, the other end of the rotating shaft 9 passes through the support frame 1 and is provided with a guide component, two mounting plates 12 are fixedly connected to the top surface of the support frame 1 near the left side, motors 13 are installed on the side walls of the mounting plates 12, the output shafts of the motors 13 are fixedly connected to the connecting cylinders 14, and a winding component is installed at one end of the connecting cylinder 14;

[0024] A first sprocket 20 is fixedly connected to the side wall of the connecting cylinder 14 , a second sprocket 21 is fixedly connected to the side wall of the rotating shaft 9 , and a chain 22 is transmission-connected between the first sprocket 20 and the second sprocket 21 .

[0025] like Figure 1 and Figure 4 As shown, the film turning assembly includes an adjusting cylinder 3 assembled at the bottom of the supporting frame 1, and a turning shovel 4 is arranged in the adjusting cylinder 3. The turning shovels 4 are all curved, and a cutting knife 5 is fixedly connected to the side wall of the middle turning shovel 4, and film loosening shovels 6 are fixedly connected to the side walls of the turning shovels 4 on both sides. Bolts are threadedly connected to the side walls of the adjusting cylinder 3, and a plurality of screw holes 7 are opened on the side walls of the turning shovel 4, and the bolts are adapted to the screw holes 7.

[0026] Among them, the connection between the adjustment cylinder 3 and the support frame 1 is connected by screws, which is convenient for subsequent replacement or cleaning, and the spacing between the turning shovels 4 can also be adjusted according to the width of the ground film; the turning shovel 4 with film loosening shovels 6 on both sides is mainly used to turn up the positions where the two sides of the ground film are attached to the soil, reduce the adhesion between the ground film and the soil, and facilitate shaking off the soil; the cutting knife 5 in the middle is used to cut the ground film and roll it into two strands to prevent the ground film from being too thick and affecting the rolling effect.

[0027] like Figure 2 and Figure 3 As shown, the guide assembly includes a guide roller 10 fixedly connected to the end face of the rotating shaft 9, and limited circular plates are fixedly connected at both ends of the guide roller 10. A plurality of protrusions 11 are fixedly connected to the side wall of the guide roller 10, and the protrusions 11 are conical. Four guide wheels 24 are rotatably connected to the inner wall of the support frame 1.

[0028] Specifically, by providing a plurality of protrusions 11 on the guide roller 10, on the one hand, a plurality of holes can be pierced on the surface of the ground film to facilitate the shedding of fine soil, and on the other hand, the adhesion between the ground film and the guide roller 10 can be increased to improve the guiding stability.

[0029] like Figure 2 and Figure 3 As shown, the winding assembly includes a round rod 16 disposed in the connecting cylinder 14 , two baffles 18 are respectively disposed on one side of the round rod 16 , a plurality of cross bars 19 are fixedly connected between the two baffles 18 , and the round rod 16 is fixedly connected to one of the baffles 18 .

[0030] Among them, when starting to roll up, the head end of the ground film needs to be wrapped or tied to the cross bar 19 so that the ground film can be pulled closer to be rolled up during the rotation process. This rolling method adopts existing mature technology, so it will not be described in detail in this solution.

[0031] like Figure 5 As shown, the side wall of the connecting tube 14 is threadedly connected with a screw 15, and the side wall of the round rod 16 is provided with a thread hole 17 adapted to the screw 15. When the ground film on the cross bar 19 is rolled up to a relatively full state, it can be removed by the screw 15, and the cross bar 19 can be replaced for continued rolling.

[0032] like Figure 2 As shown, the bottom surface of the support frame 1 near the right side is equipped with an auxiliary wheel 23. It can play an auxiliary role in the winding process and can keep the support frame 1 in a horizontal position when not winding.

[0033] The working principle of the utility model is as follows: firstly, the connection frame 2 is connected with the external traction device, and then the shoveling depth of the soil turning shovel 4 is adjusted according to the covering depth of the ground film, the bolts are loosened, and then the soil turning shovel 4 is pulled down to a suitable depth, and then the bolts are tightened to insert it into a suitable screw hole 7 to fix the soil turning shovel 4, and then the traction device first pulls the support frame 1 to move a certain position, so that the soil turning shovel 4 reaches a suitable depth of the soil, and then the ground film passes between the guide wheels 24, bypasses from the lower side of the guide roller 10, and then wraps around the cross bar 19;

[0034] Then the traction equipment drives the support frame 1 to move, and starts the motor 13 at the same time. The output shaft of the motor 13 drives the cross bar 19 to rotate through the connecting cylinder 14 to reel in the ground film. At the same time, the connecting cylinder 14 drives the first sprocket 20 to rotate, and the first sprocket 20 drives the rotating shaft 9 to rotate through the chain 22 and the second sprocket 21. The rotating shaft 9 drives the guide roller 10 to rotate, which is used for guiding and conveying the waste ground film. By shoveling up the soil and the ground film, the adhesion between the ground film and the soil can be reduced, the probability of tearing during reeling can be reduced, and the continuity of the operation can be improved.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
