[0032] The present application provides an agricultural planting film covering device, which is mainly used to solve the problem in the prior art that the film covering operation cannot be carried out smoothly due to the uneven terrain in the hilly area, and may even damage the equipment or affect the film covering quality, and provides the following technical solutions. Figure 1-Figure 5 Make a detailed description:

[0033] An agricultural planting film covering device, comprising:

[0034] There are two mounting plates 1, and a support plate 2 is fixed at the bottom of the mounting plates 1;

[0035] The telescopic plate 3 is spaced between the inner side walls of the two mounting plates 1, and the length of the telescopic plate 3 is adjustable;

[0036] A winding roller 4 is rotatably arranged between the middle parts of the two mounting plates 1, and a ground film 5 is wound on the surface of the winding roller 4;

[0037] A connecting member 6 is provided on the mounting plate 1 and is used for installing and removing the winding roller 4;

[0038] The compression ropes 7 are arranged on both sides of the top of the ground film 5, and the compression ropes 7 are used to compress the ground film 5;

[0039] A winding mechanism 8 is arranged above the winding roller 4, and is used for winding and pressing the rope 7;

[0040] The traction rod 9 is used for traction of the ground film 5 and the compression rope 7 . The free ends of the ground film 5 and the compression rope 7 are both connected to the traction rod 9 .

[0041] The agricultural planting film covering process description:

[0042] The first step is to first stably place the support plate 2 on the ground, and then adjust the length of the telescopic plate 3 according to the width of the working terrain to adapt to different working width requirements;

[0043] The second step is to install the winding roller 4 between the two mounting plates 1 through the connecting piece 6 to ensure that the ground film 5 can be freely unfolded;

[0044] The third step is to connect the free ends of the ground film 5 and the compression rope 7 to the traction rod 9, which is used to pull the entire device forward while maintaining the tension of the ground film 5 and the compression rope 7;

[0045] In the fourth step, the operator holds the traction rod 9 and moves forward along the predetermined path. The device automatically unfolds the ground film 5 during the moving process and presses it on the ground through the pressing rope 7;

[0046] In the fifth step, after the ground film 5 is unfolded to an appropriate length and soil is covered on both sides of the ground film 5, the reeling mechanism 8 is operated to reel in the pressing rope 7, thereby completing the film covering operation of a section of the area.

[0047] The agricultural planting film covering device adapts to working terrains of different widths by adjusting the length of the telescopic plate 3. The ground film 5 is unrolled from the winding roller 4, and the tension is maintained by the traction rod 9. As the traction rod 9 moves forward, it is evenly laid on the ground. The compression rope 7 applies pressure to both sides of the ground film 5 to ensure that the ground film 5 is firmly pressed on the ground. The setting of the winding mechanism 8 can facilitate the winding or release of the compression rope 7.

[0048] like Figure 4 As shown, in some embodiments, the telescopic plate 3 includes a hollow plate 301 arranged between two mounting plates 1, the inner side wall of the mounting plate 1 is connected to an extension plate 302, and the end of the extension plate 302 away from the mounting plate 1 slides and is inserted into the hollow plate 301, and one side of the hollow plate 301 is structured with strip-shaped through holes 3011 at intervals, and a connecting rod 3021 is fixedly provided on one side of the extension plate 302 located inside the hollow plate 301, and the connecting rod 3021 slides and is inserted into the strip-shaped through hole 3011. More specifically, according to the width of the field, the operator pushes or pulls the extension plate 302 to slide along the length direction of the hollow plate 301. When the extension plate 302 slides to the appropriate position, the connecting rod 3021 stops moving in the corresponding strip-shaped through hole 3011. At this time, the support plate 2 is fixed to ensure that the telescopic plate 3 is at an appropriate length.

[0049] like Figure 4 As shown, in some embodiments, the connecting member 6 includes an adjusting rod 601 threadedly connected to the side wall of the mounting plate 1, one end of the adjusting rod 601 is rotatably connected to a conical slider 602 through a bearing, and both ends of the winding roller 4 are constructed with conical grooves 401 that are compatible with the conical slider 602. More specifically, the adjusting rod 601 is connected to the side wall of the mounting plate 1 through a thread, and its extended length can be adjusted by rotating the adjusting rod 601 to adapt to winding rollers 4 of different sizes or to perform fine-tuning according to operating requirements. When the winding roller 4 needs to be installed, the operator unscrews the adjusting rod 601 to an appropriate length, then aligns the conical slider 602 with the conical groove 401 at the end of the winding roller 4, and gently pushes it in. Once the conical slider 602 is fully inserted into the conical groove 401, the mechanical locking between them ensures that the winding roller 4 will not accidentally fall off or shift during operation, thereby maintaining the stability and continuity of the laminating operation.

[0050] like Figure 3 As shown, in some embodiments, the winding mechanism 8 includes an installation box 801 fixedly embedded in the middle of the telescopic plate 3, the bottom side of the installation box 801 is rotatably connected to a rotating rod 802, both ends of the rotating rod 802 are fixedly provided with winding disks 803, the compression rope 7 is wound on the winding disks 803, and a driving member for driving the rotating rod 802 to rotate is provided inside the installation box 801, the driving member includes a driven bevel gear 804 fixedly provided in the middle of the rotating rod 802, and the top of the installation box 801 is rotatably connected to a driving rod 805, the driving An active bevel gear 806 is fixedly provided at the bottom end of the rod 805, and the active bevel gear 806 is meshed with the driven bevel gear 804. More specifically, when it is necessary to reel in the compression rope 7, the operator rotates the driving rod 805. Since the active bevel gear 806 is meshed with the driven bevel gear 804, the rotation of the driving rod 805 drives the active bevel gear 806 to rotate, and then the driven bevel gear 804 and the rotating rod 802 are rotated together through gear transmission, thereby driving the winding drum 803 to rotate, and then realizing the rotation of the compression rope 7.

[0051] like Figure 5 As shown, in some embodiments, a rectangular channel 901 is constructed in the middle of the traction rod 9, and the free end of the ground film 5 is inserted into the interior of the rectangular channel 901. A locking bolt 10 is threadedly connected to the position of the surface of the traction rod 9 corresponding to the rectangular channel 901. More specifically, when the ground film 5 needs to be installed on the traction rod 9, the operator passes the free end of the ground film 5 through the rectangular channel 901 in the middle of the traction rod 9. In order to ensure that the ground film 5 does not move during the traction process, the operator tightens the locking bolt 10. As the bolt is gradually screwed in, it will apply pressure to the ground film 5 and lock it firmly in the rectangular channel 901. This design is simple and reliable, and can ensure that the ground film 5 will not slip out of the traction rod 9 under various conditions.

[0052] like Figure 5 As shown, in some embodiments, a ring is fixedly provided at one end of the locking bolt 10 located outside the rectangular channel 901, and the free end of the compression rope 7 is connected to the ring. More specifically, the free end of the compression rope 7 is connected to the ring. This connection method can be knotting, buckling or other quick connection mechanisms, which ensures that the compression rope 7 can maintain a stable tension during the traction process, and is convenient for the operator to adjust or disassemble it as needed.

[0053] like Figure 4 As shown, in some embodiments, stakes 201 are fixed at the four corners of the bottom surface of the support plate 2, and the bottom of the stakes 201 is conical. More specifically, before the film covering operation begins, the operator places the support plate 2 at a predetermined position, and then uses force to insert the stakes 201 into the soil from the four corners. Due to the conical design of the bottom of the stakes 201, they can easily penetrate the soil surface and penetrate to a certain depth, thereby providing stable support for the support plate 2.

[0054] like Figure 4 As shown, in some embodiments, an L-shaped notch 101 is constructed on one side of the bottom of the mounting plate 1, and the L-shaped notch 101 is adapted to the size of the traction rod 9. More specifically, the design of the L-shaped notch 101 allows the traction rod 9 to be conveniently stored on the mounting plate 1 when not in use, thereby reducing the space occupied by the device and facilitating transportation and storage. When the traction rod 9 is needed, the operator can take the traction rod 9 out of the L-shaped notch 101.

[0055] like Figure 4 As shown, in some embodiments, a handle 11 is hinged on the top of the telescopic plate 3. More specifically, the handle 11 can be provided to facilitate staff to move the device, making it more portable.

[0056] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
