Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a film-laying and hole-seeding device. Background Art

[0002] my country is a mountainous country, and many arable lands are located in hilly and mountainous areas. The land is relatively small and not suitable for large agricultural machinery operations. In the past, cattle and horses were used for field cultivation and planting. In recent years, fewer and fewer farmers have raised livestock and cultivated fields. Everyone thinks that it is not cost-effective to raise a livestock on a few acres of land, which is only used for a few days a year and needs to be fed all year round.

[0003] In order to solve the above problems, micro-tillage machines have emerged to solve the problem of field farming. Due to the continuous development of science and technology, electric vehicles have replaced bicycles as the means of transportation for farmers, and rack carts have also been eliminated. At present, electric vehicles have been widely used in rural areas of my country, and electricity is more convenient than oil. By adding satellite navigation systems, spraying, fertilizing, drip irrigation tape laying, film laying, hole sowing and other mechanisms to electric four-wheelers, spraying, fertilizing, film laying, drip irrigation, hole sowing and other combined operations can be completed at one time.
