Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology, and in particular to a mulching machine for tobacco planting. Background Technology

[0002] Tobacco is an important economic crop in my country. During its cultivation, mulching technology is widely used to achieve the purposes of heat preservation, moisture retention, fertilizer retention, weed control, and promoting early and rapid growth of tobacco seedlings. Mulching is a key link in tobacco production, and its quality directly affects the growth environment of tobacco seedlings and the final yield.

[0003] Currently, in agricultural production, the mulching machines commonly used require operators to manually rotate the screw to adjust the film rollers when changing or installing them. This process is time-consuming, labor-intensive, and particularly detrimental to continuous operation, severely impacting production efficiency. Furthermore, the tightness of manual operation relies entirely on personal experience, easily leading to uneven clamping force. Insufficient clamping force causes the film roller to loosen due to inertia during rotation, resulting in loose and wrinkled mulch. Excessive clamping force increases rotational resistance, potentially causing the mulch to deform or break. Additionally, manual alignment is not precise, easily leading to mulching path deviation. Moreover, traditional mulching machines typically lack rapid overall lifting mechanisms, making it difficult to quickly adjust to different ridge heights in tobacco fields. Furthermore, the film pressing and soil covering components are often fixed or have limited adjustment ranges, failing to accurately adapt to different mulch widths and soil conditions, resulting in inadequate film pressing and soil covering, affecting windbreak and moisture retention. Therefore, these machines are inconvenient for mulching use and cannot meet customer needs.

[0004] Therefore, those skilled in the art have provided a mulching machine for tobacco planting to solve the problems mentioned in the background art. Summary of the Invention

[0027] In this embodiment: By setting up a concave frame 1, an electric cylinder 2, a drive box 3, a dual-shaft motor 4, a screw 5, a rectangular plate 6, a convex plate 7, an L-shaped plate 8, and a convex clamping plate 9, this utility model can conveniently clamp, limit, rotate, and cover mulch films of different sizes.

[0028] Reference Figure 1 and Figure 4 The film pressing assembly 12 includes a film pressing roller 121, a movable plate 122 is fixedly connected to the top of the film pressing roller 121, a slide frame 123 is embedded in the top of the horizontal plate 11, the inner surface of the slide frame 123 is slidably connected to the outer surface of the movable plate 122, the top of the movable plate 122 extends above the slide frame 123 and is fixedly connected to a limiting plate 124, and the outer surface of the limiting plate 124 is tightly fitted to the connection point of the horizontal plate 11.

[0029] In this embodiment: By setting up a film pressing roller 121, a movable plate 122, a sliding frame 123 and a limiting plate 124, the present invention can conveniently compact the mulch film.

[0030] The implementation principle of this utility model is as follows: In use, the device is firmly installed or hung on the rear of a tractor such as a micro-tiller or tractor by the two mounting brackets on the top of the concave frame 1. Then, the rolled film roller is placed between the two convex clamping plates 9, so that the two ends of the core shaft of the film roller are initially aligned with the grooves of the two convex clamping plates 9. Then, the external controller of the dual-axis motor 4 is started, so that the output end of the dual-axis motor 4 drives the screws 5 on the left and right sides to rotate synchronously. Since the screws 5 and the rectangular plate 6 are connected by threads, and the rectangular plate 6 slides with the guide groove 14 on the top of the drive box 3 through the guide plate 13 on its top, the two rectangular plates 6 move precisely towards each other along the guide groove 14 under the drive of the screws 5. The movement of the rectangular plates 6 drives the convex plate 7 to slide along the slide rail 15 through the connection, so that the two L-shaped plates 8 fixed at the bottom of the convex plate 7 and the convex clamping plates 9 move closer to each other synchronously until the two ends of the core shaft of the film roller are firmly clamped. This process realizes the rapid and automatic centering and clamping limit of the film roller. Next, based on the actual height of the tobacco ridge to be covered with film, the electric cylinder 2 is controlled to move, so that the extension end of the electric cylinder 2 pushes or pulls the drive box 3 to rise and fall smoothly along the limiting groove 17 on the inner side of the concave frame 1. This adjustment makes the entire clamping and covering mechanism reach a suitable height from the ground, ensuring that the film can be accurately laid in the best position on the ridge surface. The cooperation between the limiting block 16 and the limiting groove 17 ensures the stability of the lifting process. Then, the tractor drives the device forward at a constant speed. The clamped film roller rotates under the action of friction, and the film is pulled out and spread on the surface of the tobacco ridge. The spread film first passes through the film pressing component 12, so that the film pressing roller 121 rolls tightly against the ridge surface under its own weight and the sliding guide of the movable plate 122 in the sliding frame 123, and performs the initial rolling of the film to make it initially adhere to the soil and prevent it from being blown away by the wind. Next, the soil turning plate 10, which is fixedly connected to the L-shaped plate 8, cuts into the bottom of the furrow on both sides of the ridge. As the machine moves forward, the soil turning plate 10 turns up the soil and guides it to the two sides of the film, thereby completing the soil covering and edge pressing operation, and firmly sealing the film on the ridge, thus realizing the covering of the film. The device is simple to operate and easy to use for covering, thus meeting the needs of customers.
