Double-crank pot clamping type transplanting mechanism for rice pot seedling transplanting machine

Abstract

The invention relates to a double-crank pot clamping type transplanting mechanism for a rice pot seedling transplanting machine and belongs to agricultural machinery. A second oval gear, a first oval gear, a driven cylindrical gear, a driving cylindrical gear and a driving chain wheel are assembled and arranged in a gear box body, wherein the driven cylindrical gear is in coaxial and fixed arrangement with the first oval gear, the driving cylindrical gear is in coaxial and fixed arrangement with the driving chain wheel, the driving cylindrical gear is engaged with the driven cylindrical gear, the first oval gear and the second oval gear are assembled, installed and engaged according to the set angle, the rotating center position parts of the first oval gear and the second oval gear are respectively and fixedly provided with a driving crank shaft and a driven crank shaft, two ends of a driving crank are respectively and fixedly connected with the driving crank shaft and a cam of a planting arm assembly according to the set angle, one end of a driven crank is fixedly installed with the driven crank shaft, the other end of the driven crank is hinged and connected with one end of a connecting rod, and the other end of the connecting rod is hinged and connected with the crank of the planting arm assembly. The double-crank pot clamping type transplanting mechanism has the advantages that the structure is simple and reasonable, the manufacture cost is low, the pot tray seedling taking and planting operation requirements are met, the operation effect is good, and the production efficiency is high.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a double-crank bowl-clamping type inserting mechanism with elliptical gears on a rice bowl seedling transplanting machine with non-uniform speed transmission. Background technique [0002] At present, my country's rice transplanter research and development level has been in the leading position in the world, but there are still problems such as root damage and long seedling delay period. The transplanting of rice pot seedlings has the characteristics of not slowing down seedlings, early tillering, increasing yield, and outstanding effects. It is the best planting method for rice. [0003] The existing transplanting mechanism of the rice pot seedling transplanting machine mainly has two modes of ejection and seedling clamping. The ejecting operation adopts the method of swinging or orderly throwing seedlings, which has high requirements for field preparation, otherwise the quality o...

AI Technical Summary

Problems solved by technology

The ejecting operation adopts the method of swinging or orderly throwing seedlings, which has high requirements for field preparation, otherwise the quality of planting operation is not easy to guarantee; the clamping operation requires the seedlings to be upright, which is difficult to transport, without a pusher device, and the production efficiency is low
