Pneumatic automatic transplanting device for transplanter

Abstract

The invention discloses a pneumatic automatic transplanting device for a transplanter. The pneumatic automatic transplanting device for the rice transplanter comprises a horizontal sliding rail, a longitudinal sliding rail, a seedling supporting pallet, a positioning plate and an transplanting component; the longitudinal sliding rail is arranged on a transplanter frame, the horizontal sliding railis slidably connected to the longitudinal sliding rail, and the seedling supporting pallet is slidably connected to the horizontal sliding rail; the positioning plate is fixedly disposed on the transplanter frame; the transplanting component comprises a first hollow tube, a second hollow tube, a support net, a third hollow tube, a first fixed plate, a movable plate, a spring assembly, an annularair bag, an intake pipe, an exhaust pipe, a second fixed plate, a first push button switch, a third fixed plate, a second push button switch, a cylinder, a push rod, a connecting piece, a first connecting rod, a ring ferrule, a rotating shaft, a digging assembly and a earth covering assembly. The pneumatic automatic transplanting device in the invention automatically transplanting seedlings into the rice field from the bottom by means of pneumatic suction, has simple structure and convenient operation, greatly reduces the damaged seedling rate and improves the survival rate of the seedling.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a pneumatic automatic rice transplanting device for a rice transplanter. Background technique [0002] The rice transplanter is a kind of agricultural machinery that implants rice seedlings into the rice fields. With the start of the domestic market demand for rice transplanters, the future development prospects are broad. Many companies in my country are involved in the development and production of rice transplanters, and foreign rice transplanter companies have also changed. In the past, the single product export method has established sole proprietorship or joint ventures to produce rice transplanters in my country. The domestic rice transplanter market has formed an international competition situation. [0003] The current common rice transplanter usually uses a mechanical interpolation head. The disadvantage is that the damage rate is high, and the needles are...

Problems solved by technology

[0003] At present, the common rice transplanter usually uses a mechanical interpolation head. The disadvantage is that the rate of damage to the seedlings is high, and the needles are easy to catch and damage the seedlings, reducing the survival rate of the seedlings. Therefore, the interpolation structure needs to be improved to enhance the competitiveness of enterprises.
