Figure 2 Figure 3 As shown, the sliding grooves 13 are through groove structures, and the sliding blocks are also arranged through the sliding grooves 13; on the outer side of the outer frame 1, a pair of connecting rods 8 are arranged; the connecting rods 8 fix the sliding grooves of the two kneading rollers 4 and the self-adjusting wheel 5 together, so that they can be lifted synchronously; the lowest end of the self-adjusting wheel 5 is slightly lower than the lowest ends of the two kneading rollers 4, and the two kneading rollers 4 are arranged at the same height.
[0029] As shown, at the ends of the connecting rods 8, two connecting rods 8 on the two sides are connected into one through a flattening cross bar 61, and the height of the flattening cross bar 61 is higher than the height of the rotating shafts of the kneading rollers 4 and the self-adjusting wheel 5; a plurality of elastic flattening wheels are arranged on the bottom surface of the flattening cross bar 61, and the plurality of elastic flattening wheels are vertically arranged at equal intervals; the elastic flattening wheel comprises an extension rod, which is vertically arranged, and the top end is fixedly connected with the bottom surface of the flattening cross bar 61, and the bottom end is connected with a roller 62; a spring 63 is arranged between the roller 62 and the bottom surface of the flattening cross bar 61, and the spring 63 is sleeved on the outside of the extension rod; the spring 63 is a compression spring, which can continuously provide a downward thrust to the roller 62, so that the roller 62 is always at the lowest end. Figure 3 As shown, in actual use, first, the ground film is sleeved on the two ground film installation rollers, and then the free ends of the upper ground film 21 and the lower ground film 31 are pulled out and passed through the gap between the two kneading rollers 4; the two kneading rollers 4 are gap-fitted, so that the ground film can pass through and the multiple layers of ground film can be rolled and kneaded, so that they are tightly connected together; after the multiple layers of ground film are kneaded by the kneading rollers 4, the free ends are pulled out and fixed at one end of the field ridge by covering soil or the like, and then the ground film laying work can be started.
[0030] Figure 2 As shown, in actual use, first, the ground film is sleeved on the two ground film installation rollers, and then the free ends of the upper ground film 21 and the lower ground film 31 are pulled out and passed through the gap between the two kneading rollers 4; the two kneading rollers 4 are gap-fitted, so that the ground film can pass through and the multiple layers of ground film can be rolled and kneaded, so that they are tightly connected together; after the multiple layers of ground film are kneaded by the kneading rollers 4, the free ends are pulled out and fixed at one end of the field ridge by covering soil or the like, and then the ground film laying work can be started.
[0031] As shown, in actual use, first, the ground film is sleeved on the two ground film installation rollers, and then the free ends of the upper ground film 21 and the lower ground film 31 are pulled out and passed through the gap between the two kneading rollers 4; the two kneading rollers 4 are gap-fitted, so that the ground film can pass through and the multiple layers of ground film can be rolled and kneaded, so that they are tightly connected together; after the multiple layers of ground film are kneaded by the kneading rollers 4, the free ends are pulled out and fixed at one end of the field ridge by covering soil or the like, and then the ground film laying work can be started. Figure 4
[0032] The outer frame 1 can be attached to various sizes of agricultural machinery via the hooking mechanism 12, or it can be manually dragged by the handle 11. The outer frame 1 is placed across the ridge, with the wheels 7 on both sides positioned at the two ends of the ridge. Then, the outer frame 1 is pulled forward. Since the free end of the multi-layer mulch film is fixed at one end of the ridge, pulling the outer frame 1 will also pull the remaining mulch film on the mulch film installation roller to lay it outward. After the two layers of mulch film are kneaded by the kneading roller 4, they form a tightly connected multi-layer mulch film, which is then tightly flattened and placed on the ridge by the flattening mechanism 6, completing the mulch film laying work. During the laying process, the height of the kneading roller 4 is automatically adjusted by the self-adjusting wheel 5. Since the lowest end of the self-adjusting wheel 5 is slightly lower than the lowest end of the kneading roller 4, when the self-adjusting wheel 5 is in contact with the top surface of the ridge, the kneading roller 4 will be kept at a height slightly higher than the top surface of the ridge, so that the kneading roller 4 is neither too high, causing the kneaded mulch film to loosen, nor too low, causing direct contact with the ridge.
[0033] Example 2
[0034] The difference between this embodiment and Embodiment 1 is that, as Figure 5 As shown, in this embodiment, a pair of automatic soil cover plates 9 are provided at the bottom rear end of the outer frame 1.
[0035] The front end of the automatic soil cover plate 9 is slightly lower than the lowest end of the wheel 7. When the device is used in the field, the front end of the automatic soil cover plate 9 extends into the ground, thereby shoveling the soil on the ground into the automatic soil cover plate 9. A baffle is set on the inner side of the automatic soil cover plate 9 to prevent the soil from spilling before reaching the highest point. The rear end of the automatic soil cover plate 9 is set as an inclined plate, and an extension plate is set inward from the highest point. The extension plate extends inward to intersect with the two edges of the mulch film. No baffle is set on the inner edge of the extension plate, so that the soil in the automatic soil cover plate 9 can be spilled from the extension plate onto the two edges of the mulch film. During the mulch film laying process, as the outer frame 1 moves forward, the automatic soil cover plate 9 will automatically shovel soil and throw it onto the two edges of the mulch film, realizing the automation of mulch film covering and fixing, saving a lot of manpower.
[0036] Example 3
[0037] The difference between this embodiment and embodiment 2 is that, as Figure 6 As shown, in this embodiment, an additional middle layer mulch film installation roller 22 is provided between the upper mulch film installation roller 2 and the lower mulch film installation roller 3, and three layers of mulch film are respectively provided on the mulch film installation roller; by expanding the number of mulch film installation rollers, the types and range of mulch films applicable to this utility model can be expanded, making it applicable to multi-layer mulch film laying work with more layers.
[0038] The above merely makes further explanation and description of the utility model in combination with specific embodiments, and all the description does not represent that the protection scope of the utility model is limited, any change or alternative scheme that can be easily thought of by any person skilled in the art within the technical range disclosed by the utility model should be covered in the protection scope of the utility model, therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
