Outline
Most of the existing solanaceous vegetable grafting machines are semi-automatic models. Due to the significant differences in the growth morphology of seedlings, the automatic seedling picking process is difficult to achieve. Based on the working requirements of the fully automatic row grafting equipment for solanaceous vegetables, an automatic scion seedling picking device was designed. This device adopted flexible gripper hands, which had strong adaptability to the growth form of seedlings. It can automatically supply, clamp, cut and transfer the scion trays, achieving the automation of seedling extraction for grafting operations, thereby promoting the upgrading of the grafting machine from semi-automatic to fully automatic operation. In order to verify the working performance of the scion picking device, taking chili seedlings in the grafting period as the object, the success rate of picking as the test index, and the thickness of the elastic piece, the structure of the clamping hand, and the scion growth offset as factors, a three-factor and three-level orthogonal test for scion picking was carried out. The test results showed that the influence degrees of the three factors on the success rate of picking, from large to small, were as follows: gripper structure, growth offset, and elastic piece thickness. The optimal combination was gripper structureⅢ, growth offset of 0~14 mm, and elastic piece thickness of 0.3 mm. The scion picking test was conducted under the optimal combination conditions. A total of 150 scions from three tray seedlings were selected as the seedlings, after experimental verification, the success rate of picking was 98.7%, meeting the performance requirements of the scion picking operation of the grafting machine.
