Design of cutting clamping mechanism of melon grafting machine
Using watermelon and gourd as scion and rootstock respectively,the grafting method was adopted,and the cutting problems of rootstock and scion and the clamping device were studied by rotary cutting.In order to make the cutting and clamping device cooperate effectively,the melon grafting cutting clamping mechanism scheme using cross-type intermittent cutting could complete the clamping and cutting work of seedlings.The device fixed the center and the radius of the cutter,taking the scion and rootstock cutting arc ratio as the lamination rate to measure the cutting quality.After calculation,to cut by the long axis,the scion cutting angle was 30°,the rootstock cutting angle was 40°,the lamination rate reached 99.05%;to cut by the short shaft,the scion cutting angle was 30°,the rootstock cutting angle was 45°,the lamination rate reached 99.14%,meeting the design requirements.In order to make the clamping device and the cutting device cooperate to obtain the cutting angle,the cutting angle matching was carried out by rotating the angle of the cutting tool holder,which was convenient and fast.The structural feasibility was verified by simulating the mechanism.
