Description

Technical Field

[0001] This utility model belongs to the field of agricultural mulch film laying technology, and in particular relates to an agricultural mulch film laying mechanism. Background Technology

[0002] Agricultural mulch film laying mechanisms are indispensable tools in modern agricultural production. They greatly improve the efficiency and quality of farmland operations, providing strong support for the healthy growth of crops. These mechanisms were originally designed to solve problems such as high labor consumption, uneven laying, and low efficiency in traditional mulch film laying processes. Through mechanized operations, they achieve automation and precision in mulch film laying. With their high efficiency, precision, and labor-saving characteristics, agricultural mulch film laying mechanisms play an increasingly important role in modern agricultural production. With the continuous advancement of agricultural technology and the improvement of intelligent technology, these mechanisms will become even more intelligent and automated in the future, bringing even more significant benefits to agricultural production.

[0003] Comparing with Chinese Patent No. CN222216636U, an agricultural mulch film laying mechanism is disclosed, including a movable frame. A support block is fixedly connected to the bottom of the movable frame, and a guide roller is rotatably connected inside the support block. A replacement mechanism is provided at the bottom of the movable frame, and a storage roller is provided on one side of the replacement mechanism. An adjustment mechanism is also provided at the bottom of the movable frame. The replacement mechanism includes a fixed groove, which is rotatably connected to one end of the storage roller. An insert block is movably connected inside the fixed groove. A sliding shaft is fixedly connected to one side of the fixed groove, and a support plate is fixedly connected to the end of the sliding shaft away from the fixed groove. A threaded shaft is rotatably connected inside the support plate. The replacement mechanism allows for the disassembly of the storage roller, facilitating easy assembly and disassembly by workers, achieving good disassembly efficiency, further improving the convenience of disassembly, and saving workers' operating time.

[0004] However, the aforementioned patents require alignment of the shaft end for disassembly and assembly, which is time-consuming and labor-intensive, and are only applicable to mulch film rolls with a core shaft, greatly limiting their applicability. Therefore, a new device needs to be designed. Utility Model Content

A flow guide protrusion 107 is provided on the bottom surface of the walking frame 101 near the first through groove 104. The cross-sectional shape of the flow guide protrusion 107 is semi-circular. The walking frame 101 is pulled by the traction frame 102 and moves under the support of the walking wheels 103. The mulch film passes through the first through groove 104, the guide roller 106 and the pressure roller 105 in sequence and is released, so that the mulch film is tightly attached to the ground under the rolling pressure of the pressure roller 105. The flow guide protrusion 107 is used to increase the smoothness of the ground flowing out of the first through groove 104.

[0028] In this embodiment: the box device includes a storage box 201, a storage cavity 202 is provided in the middle of the storage box 201, the bottom of the storage cavity 202 is arc-shaped, a second through groove 203 is provided at the bottom end of the storage cavity 202, and two latches 205 are symmetrically installed at both ends of the storage box 201; two limiting grooves 204 are symmetrically provided in the middle of the storage box 201, and the limiting grooves 204 penetrate the storage box 201; when the mulch film roll is placed into the storage cavity 202 in the storage box 201, the storage cavity 202 supports the mulch film roll to rotate and release the mulch film, which is released through the second through groove 203 and out of the storage box 201; the latches 205 are fixed in place with the locking plate 303; and the limiting grooves 204 are used to limit the up and down movement of the slide 304.

Then, the end of the plastic film is passed through the second through groove 203, the first through groove 104, the guide roller 106 and the pressure roller 105 in sequence and fixed on the ground. Then, the upper box cover 301 is placed on the storage box 201 and the locking plate 303 is inserted into the locking buckle 205 to fix it. The upper box cover 301 pushes the lower limit plate 305 through the spring 306, which drives the slide 304 to move down along the limit slide groove 204 and presses on the top of the plastic film roll to prevent the plastic film roll from jumping when rotating. Then, the traction frame 102 pulls the walking frame 101 to move under the support of the walking wheels 103. The storage cavity 202 supports the rotation of the plastic film roll to release the plastic film, so that the plastic film is pressed tightly against the ground under the rolling of the pressure roller 105.
