Description

Technical Field

[0001] This application relates to the field of laying device technology, and in particular to a laying device. Background Technology

[0002] During crop cultivation, mulch film is often laid on the ground to increase soil temperature, retain moisture, prevent soil compaction and fertilizer loss, control weeds and pests, improve soil physical properties, increase photosynthesis, and control soil salinization. Currently, to improve the efficiency of mulch film laying, tractor-trailers are used to move the film rolls, allowing them to unroll automatically and achieve automatic mulch laying. However, when laying mulch film on cultivated ridges, the film needs to be bent on both sides. Since the inclination angles of different ridges are inconsistent, existing mulch film laying machines have low applicability and cannot bend the film according to the shape of the ridges. Therefore, a laying device is provided. Utility Model Content

[0005] A laying device includes a connecting roller, with side rollers on both sides of the connecting roller via a rotating mechanism. The rotating mechanism allows the angle between the side rollers and the connecting roller to be adjusted. The rotating mechanism includes grooves formed at both ends of the connecting roller. A connecting plate is fixedly connected to the end of each side roller near the connecting roller. A rotating shaft is fixedly connected to one end of each connecting plate. The rotating shaft is rotatably mounted inside the groove. A gear is fixedly connected to the middle of the rotating shaft. An electric cylinder is fixedly connected to the closed end of the inner surface of the groove. A push plate is fixedly connected to the telescopic end of each electric cylinder. A toothed plate is fixedly connected to the surface of the push plate, and the toothed plate meshes with the gear.

[0006] Preferably, an elastic membrane is fixedly connected to the open end of the tank, an installation port is provided in the middle of the elastic membrane, and the connecting plate is fixedly connected to the elastic membrane through the installation port.

[0007] Preferably, the surface of the connecting roller is provided with a connecting frame, which is mounted on the surface of the mobile device by bolts.

[0008] Preferably, the middle part of the connecting roller is a telescopic structure, the middle part of the connecting roller includes an inner cylinder and an outer cylinder, and the inner cylinder and the outer cylinder are slidably inserted into each other. An electric telescopic rod is fixedly connected inside the outer cylinder, and the telescopic end of the electric telescopic rod is fixedly connected to the inner cylinder.

The connecting roller 1 and the side roller 2 can make the mulch film bend according to the shape of the ridge. Specifically, the electric cylinder 6 is driven to move, which drives the push plate 7 and the toothed plate 10 to move, thereby driving the gear 9, the connecting plate 11 and the side roller 2 to rotate, thereby adjusting the angle between the side roller 2 and the connecting roller 1.
