Description

Technical Field

[0001] The utility model belongs to the technical field of film spraying devices, in particular to a film spraying device for degradable ground film. Background Art

[0002] Biodegradable liquid mulch is commonly known as liquid mulch. It is made from crop straw and is a polymer material formed by special processing of natural polymer substances such as lignin, collagen, surfactants, and soil water-retaining agents. When used, herbicides can be mixed into it and added with 20 to 30 times the amount of water. It can be sprayed directly on the surface of the farmland. It can immediately form an insulating film that is combined with the soil surface. It will be 100% degraded in about 90 days. This biodegradable film can maintain soil moisture and protect field moisture conditions. It can also raise the temperature of the 5 to 15 cm soil layer by 1 to 6 degrees.

[0003] According to a liquid ground film spraying device disclosed in the patent application number CN218834852U, by setting a protective mechanism, when ink is sprayed on the edge of the field, two motors drive the cranks to rotate, and the two connecting rods rotate immediately, thereby causing the two second rods to rotate and unfold, and the two shielding cloths unfold accordingly, which can achieve a good protective effect during film spraying. However, there are still the following shortcomings, such as:

[0004] The device cannot adjust the spacing between the wheels and cannot flexibly change the spacing between the wheels according to the actual conditions of different cultivated land. If the spacing between the furrows in the cultivated land is large or small, the wheels may press on the plants or the soil around the plants, causing adverse effects on plant growth. Therefore, we proposed a spraying device for degradable mulch. Utility Model Content
