Topic: Design and Development of Cuttage and Film Covering Multi-functional Machine for Low Tunnels
Abstract: In order to adapt to the vegetable and fruit arches planting mode in some areas, to solve the traditional arches rely on manual construction, labor intensity and low efficiency of the problem. We have designed a cuttage and film covering multi-functional machine for low tunnels. It is composed of automatic rod feeding device, double inserting device, film covering device and marching device. The working parameters such as insertion spacing and number of insertion frames are set. Through the walking mechanism to complete the fixed distance walking and auxiliary walking straight function. Automatic rod feeding device is used to achieve automatic feeding of the shed rod. Using double inserting device to complete the work of bending and inserting poles. Automatic mulching operation is realized by the mulching device. The field test shows that the machine operates at a maximum speed of 1.2 km/h. The average accuracy rate of navigation line extraction is 96.2%. The success rate of entering the pole was 94.1%. The success rate of inserting frames was 89.3%. The arch mulching rate was 100%, and the film breakage rate was 1.1%. It effectively improves the working efficiency of the cuttage and film covering multi-functional machine for low tunnels and the stability of arches construction.
