[0028] The utility model discloses adopt hydraulic cylinder 23 drive adjustment arm 22, and further make furrower 21 rotate around connecting shaft 24, can flexibly adjust the soil -entering angle of furrower 21, make it can better adapt to different hardness and type's soil, to meet the planting demand of different crops, has improved the application range of mulch machine in a variety of crop planting, convenient and practical.

[0029] Among them, the connecting shaft 24 and the rack 1, the connecting shaft 24 and the furrower 21 and the adjustment arm 22 and the connecting shaft 24 are all hinged, and this connection mode makes the furrower 21 can flexibly adjust the soil -entering angle, under different soil conditions, the telescopic hydraulic cylinder 23 drives the adjustment arm 22 to rotate, and then makes the furrower 21 rotate around the connecting shaft 24, realizes the adjustment of the soil -entering angle.

[0030] In one of the embodiments, the mulch bracket 4 includes a support frame 41 and a connecting frame 42, the support frame 41 is arranged on the rack 1, the two ends of the support frame 41 are provided with the connecting frame 42, the end of each connecting frame 42 away from the support frame 41 is provided with a connecting hole, the opposite surfaces of the two connecting frames 42 are provided with the mulch roll 8, the combined design of the support frame 41 and the connecting frame 42 can provide a stable support environment for the mulch roll 8, the operator can easily place the mulch roll 8 between the two connecting frames 42 and fix it through the connecting hole, when the mulch roll 8 is used up, it can be quickly replaced, improving the efficiency of mulching operation.

[0031] Further, the support frame 41 is provided with at least one first mounting hole, and the connecting frame 42 is provided with a second mounting hole at the end away from the connecting hole. When the second mounting hole is aligned with any of the first mounting holes, the connecting frame 42 and the support frame 41 are connected by bolts and nuts 53. When facing a larger size of mulch roll 8, the first mounting hole and the second mounting hole with wider spacing can be selected to align, and vice versa. Through this flexible adjustment method, the adaptability of the mulch bracket 4 to mulch rolls 8 of different sizes is enhanced, and the installation difficulties caused by the size mismatch of the mulch roll 8 are reduced.

[0032] In one embodiment, the film burying and compacting assembly 5 further comprises a screw rod 52 and a nut 53, the nut 53 is arranged on the frame 1, one end of the screw rod 52 penetrates through the nut 53 and is connected with the compacting wheel 51, due to the threaded cooperation between the screw rod 52 and the nut 53, the screw rod 52 will produce axial movement, thereby pushing the compacting wheel 51 to move up and down, that is, the operator can accurately control the distance between the compacting wheel 51 and the ground, that is, adjust the film burying depth according to the actual soil condition and film laying requirement, so that the film burying machine can quickly adapt to diversified agricultural production needs, whether it is shallow burying film for shallow-rooted crops or deep burying film for deep-rooted crops, it can be easily coped with, and the versatility and practicality of the film burying machine are enhanced.

[0033] Further, the surface of the compacting wheel 51 is provided with staggered grooves, which can increase the friction between the compacting wheel 51 and the film and the soil surface, when the film is laid on the ground and the compacting wheel 51 rolls, the grooves are embedded in the soil, so that the compacting wheel 51 is not easy to slip, ensuring the stability of its movement, and the film edge can be more smoothly and continuously pressed into the soil, improving the efficiency and quality of film burying.

[0034] In one embodiment, the ditching device 6 comprises a connecting rod 61, a roller 62 and an inclined rod 63, one end of the connecting rod 61 is connected with the frame 1, the other end of the connecting rod 61 is connected with the roller 62, and the two ends of the inclined rod 63 are connected with the connecting rod 61 and the roller 62 respectively, when the film burying machine works, the roller 62 rolls along the ridge and furrow, and the ridge and furrow surface that may be not flat after ditching and film burying is trimmed to make it more flat, creating good conditions for subsequent planting or other agricultural operations. Moreover, the inclined rod 63 can connect the connecting rod 61 and the roller 62 into a stable triangular structure (or a similar triangular structure), so that even if the film burying machine encounters uneven ground or large resistance during movement, the roller 62 can always be in the appropriate position, ensuring the normal work of the ditching device 6 and avoiding poor leveling effect or component damage due to unstable structure.

[0035] In one embodiment, a towing hook 7 is further included, and the frame 1 is provided with the towing hook 7, in actual agricultural operation scenarios, the film burying machine itself has no power system and needs to rely on external traction equipment such as a tractor to drive work. The towing hook 7 serves as a key connection hub between the two, smoothly transmitting the traction force of the tractor to the film burying machine, so that the film burying machine can carry out film burying operation according to the predetermined route and speed.

[0036] The working principle of the film burying machine is as follows:

[0037] 1. ditching operation: after starting the mulching machine, the hydraulic system supplies oil to the hydraulic cylinder 23, the piston rod of the hydraulic cylinder 23 starts to stretch and retract, and the ditching plow 21 is driven to rotate around the connecting shaft 24 by the adjusting arm 22; when facing hard soil, the hydraulic cylinder 23 is stretched, so that the soil entering angle of the ditching plow 21 is increased, and the ditching plow 21 cuts into the soil more powerfully; when encountering soft soil, the hydraulic cylinder 23 is retracted, the soil entering angle of the ditching plow 21 is reduced, and the ditching plow 21 opens a ditch suitable for laying mulch on the land according to the soil condition, laying the foundation for subsequent mulch laying.

[0038] 2. land leveling: after the ditching plow 21 finishes ditching, the leveling plate 3 immediately levels the soil turned over by the ditching, pushes and compacts the irregular soil on both sides and the bottom of the ditch to create a relatively flat surface, facilitates mulch adhesion, and reduces the risk of mulch suspension and wrinkles.

[0039] 3. mulch laying: the mulch roll 8 placed on the mulch bracket 4 starts to release mulch, and the support frame 41 and the connecting frame 42 of the mulch bracket 4 stably support the mulch roll 8, ensuring that it can rotate smoothly, so that the mulch is smoothly and continuously laid on the leveled land.

[0040] 4. burying and compacting the film: as the mulch laying machine moves forward, the burying and compacting assembly 5 starts to work, the compacting wheel 51 rolls and presses the edge of the just-laid mulch under the action of gravity and the forward pushing force of the mulch laying machine, and the mulch is tightly pressed into the soil; if it is necessary to adjust the burying depth, the rotating screw 52 moves up and down due to the screw transmission between the screw 52 and the nut 53, so as to adapt to the requirements of different soil and crops for the burying depth; the staggered grooves on the surface of the compacting wheel 51 enhance the friction between the compacting wheel 51 and the mulch and the soil, making the compaction more stable, and also improving the soil permeability and preventing the mulch from sticking.

[0041] 5. ridge and furrow leveling: finally, the roller 62 rolls along the ridge and furrow, and the inclined rod 63 ensures the stability of the structure of the roller 62; the roller 62 rolls while further flattening the irregular ridge and furrow after ditching and burying the film, thus completing a complete and high-quality mulch laying process.

[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
