Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a hemp film and lawn cutter. Background Art

[0002] Raising seedlings is an important part of mechanical transplanting of rice. In the traditional raising seedling process, there have always been problems such as weak root system of seedlings, easy scattering of seedlings, and high rate of missed planting, which has become a bottleneck restricting the application of mechanical transplanting. However, with the help of hemp seedling raising film (hemp film) for raising seedlings, the roots of rice seeds can be naturally intertwined, and the root system of seedlings has strong intertwining force. The use of hemp seedling raising film is generally to cut it into the size of seedling raising trays, and then manually spread it piece by piece on the bottom of the seedling raising tray, and then fill it with seedling raising soil, and finally sow and raise seedlings, but this will consume a large number of seedling raising trays, thereby increasing the cost of raising seedlings. Directly spreading a large piece of hemp seedling raising film on the seedbed, spreading seedling raising soil on it, and finally sowing and raising seedlings will greatly reduce the cost of raising seedlings, but before transplanting, the raised seedlings need to be divided into rectangular blocks of the size of the seedling raising tray to meet the transplanting requirements. The transplanting of other seedlings and lawns needs to meet the same requirements. Therefore, the research and development of cutting equipment with simple structure and stable operation is a problem that needs to be solved at present. Utility Model Content
