Description

Technical Field

[0001] The present invention relates to the technical field of saline-alkali soil film mulching, and particularly to a novel saline-alkali soil film mulching machine. Background Art

[0002] Saline-alkali soil film mulching is an effective improvement technology. Its core advantage lies in significantly improving the soil environment of saline-alkali land through physical barrier and ecological regulation. Specifically, the film mulch can inhibit soil water evaporation, reduce the rise of salt with water to the ground surface, thereby reducing the salt concentration in the surface soil and alleviating the salinization problem; at the same time, the film mulch can also increase the soil temperature, promote seed germination and seedling growth, especially suitable for crops planted in early spring or late autumn. In addition, the film mulch has a good water retention effect, reduces water loss, and improves water resource utilization efficiency, especially suitable for arid and less rainy areas. It can also inhibit weed growth, reduce the use of herbicides, lower production costs and environmental pollution. Long-term film mulching can also improve the soil structure, prevent soil compaction, enhance soil air permeability and water permeability, and promote microbial activities, improving soil fertility. Traditional film mulching machines are difficult to adapt to the characteristics of saline-alkali soil such as soil compaction and viscosity, and are prone to problems such as uneven film mulching and film damage. Existing film mulching machines generally use tractors as the power source to carry out film mulching operations, but tractors have limitations on the operating environment. In some relatively concave plots, tractors often cannot go down for operation. Moreover, existing film mulching machines often cannot perfectly complete the soil covering operation step. The reason is that there will be incomplete soil covering after the film is laid, and manual inspection and filling are often required; for example, Chinese Patent No. 202411632149.1 discloses a rice and wheat saline-alkali soil film mulching machine and its use method: including: a support cylinder, with symmetrical outer shells fixedly and penetratingly connected at both ends, one end of a film roller frame is fixedly connected to the middle side wall of the outer shell, and a traction frame is rotatably installed on the cross bar of the film roller frame; also including: a support frame, the connecting plate at the top of which is fixedly installed on the outer wall of the outer shell, a wheel ring is coaxially and rotatably sleeved on the disk at the bottom of the support frame, and a coaxially arranged toothed ring is fixedly installed on the inner wall of the wheel ring; although the above technical solution can ensure a certain amount of soil collection through the soil collection mechanism, due to the movement mode of the soil collection mechanism and the uneven floating soil on the working site, it may lead to the situation that the soil collection mechanism cannot collect soil, resulting in a reduction in the subsequent soil covering amount of the film and requiring manual intervention.
