Description

Technical Field

[0001] This utility model relates to the field of agricultural mulching device technology, specifically to a mulching device for seed sowing. Background Technology

[0002] In agricultural production, mulching technology is widely used for purposes such as heat preservation, moisture retention, and weed suppression. Traditional mulching devices typically employ a fixed structure, using mechanical or manual traction to lay the film on the soil surface, followed by covering it with soil to secure it. However, existing technologies have the following shortcomings:

[0003] The film is not firmly fixed: After the film is covered, it is easily blown up by the wind before the soil is covered, making it difficult to cover with soil. It is necessary to manually press the film with soil before covering with soil. However, this is inefficient and cannot evenly press the film across the entire width, so the effect is not ideal.

[0004] Poor adaptability: The soil covering mechanism has a fixed angle and cannot be flexibly adjusted according to the terrain or crop row spacing;

[0005] Therefore, there is an urgent need for a seed sowing mulching device to address the technical problems described above. Utility Model Content

[0020] 1. The film pressing mechanism is located at the rear end of the bottom frame and in the middle of the adjustable film covering mechanism. When the adjustable film covering mechanism is covering the film, the rollers and rubber sleeves on the film pressing mechanism will press down on the film covering the ground, thus holding the film down and preventing it from being blown away by the wind. This makes it easier for the soil covering mechanism to cover the soil, and prevents the film from being blown away by the wind, which would hinder the frequent soil covering. Moreover, the rollers and rubber sleeves will roll on the film with the device, so they will not damage the film. Furthermore, due to the spring setting, a downward force is applied to the rear support rod, which keeps the rollers and rubber sleeves rolling on the film. At the same time, if there are large clods of soil, they will also lift the rollers and drive the rear support rod to rotate upward, so as not to damage the film.
