Rice pot seedling planting machine planting arm

Abstract

The invention discloses a planting arm of a rice pot seedling planting machine. A planting arm shell and a planting arm cover are fixed together to form an installing chamber; a pushing rod, a shifting fork and a radial cam are arranged in the installing chamber, the stretching end of the pushing rod is fixedly provided with a hole digger, and the radial cam is installed in the planting arm shell through a rotation shaft; a left axial cam and a right axial cam are fixed to the rotation shaft and arranged on the two sides of the radial cam; the planting arm cover is rotatably provided with a left swing arm and a right swing arm, the corresponding swing arms are matched with the cam surfaces of the corresponding axial cams in the installing chamber, and the corresponding swing arms are fixedly connected with corresponding seedling taking clamps outside the installing chamber. When power is input into the rotation shaft, the pushing rod returns back at the seedling taking point, and the seedling taking clamps grab seedlings from a pot tray from an opened state to a closed state; at seedling planting points, the hole digger stretches out to dig holes in soil and then returns back, at the moment, the seedling taking clamps loosen, the seedlings are planted in the holes, therefore, the seedlings cannot be damaged in the whole seedling planting process, and the planting arm can be widely applied to the rice pot seedling planting machine.

Description

technical field [0001] The invention relates to the technical field of potted rice seedling planting machines, in particular to a planting arm for potted rice seedlings. Background technique [0002] Rice pot seedling raising technology is a new technology that has emerged in recent years. Rice pot seedling raising can save seeds, pesticides, fertilizers and water resources. When transplanting, there is no need to slow down seedlings and early tillering, and can achieve high rice yields and increased income. . [0003] The transplanting of rice pot seedlings is realized by a planting machine, and its core component is the planting arm. Chinese invention patent application CN103125188A discloses a pot seedling planting arm for rice. Its working process is to first take out the seedlings from the pot tray with the seedling picker, and then use the seedling pusher to plant the pot seedlings in the mud field, and take the seedling clip The opening and closing of the seedling p...

AI Technical Summary

Problems solved by technology

Yet ideal transplanting agronomy is, dig a pit earlier in the mud, then plant the seedlings in the mud pit, so as not to damage the seedlings in the process of planting seedlings, and the above-mentioned known planting arms are due to the opening and closing of the seedling clips and The expansion and contraction of the seedling pusher are interrelated. The seedlings are pushed into the mud by the pusher. It is impossible to dig a hole first and then plant the seedlings.
