Sweet potato seedling transplanter

Abstract

The sweet potato seedling transplanter comprises a rack, a sweet potato seedling conveying device and a sweet potato seedling clamping and transplanting device, the sweet potato seedling conveying device comprises a conveying belt, and the conveying belt is wound on the rack in a closed path; the sweet potato seedling clamping and inserting device comprises a driving mechanism, a clamping mechanism and a guide swing rod, the driving mechanism comprises a driving shaft, a rocker arm and a planet shaft, the driving shaft is arranged on the portion, on the front side of the rear edge of the conveying belt, of the rack, the clamping mechanism is hinged to the planet shaft, and the clamping adjusting end of the clamping mechanism makes contact with the driving shaft; a clamping part of the clamping mechanism is located on the rear side of the conveying belt, the fixed hinge end of the guide swing rod is hinged to the portion, on the rear side of the conveying belt, of the rack, and the swing end of the guide swing rod is hinged to the position, close to the clamping part, of the clamping mechanism. The transplanting machine is short in sweet potato seedling clamping and transferring time and distance, the sweet potato seedlings cannot be bent in the transferring process, and the transplanting machine has the advantages that the transplanting efficiency is high, and the transplanting survival rate of the sweet potato seedlings is high.

Description

technical field [0001] The invention relates to a sweet potato seedling transplanting machine, which belongs to the technical field of sweet potato automatic planting equipment. Background technique [0002] The transplanting mechanism of the existing sweet potato seedling transplanting machine is such as the Chinese utility model patent "authorized announcement number: CN211861070U; authorized announcement date: November 06, 2020; name: a new type of sweet potato seedling wheel-type seedling delivery mechanism". It shows that after the clamping part of the clamping mechanism clamps the front end of the sweet potato seedlings, it needs to move backward horizontally for a long distance, and then move downwards to realize the planting operation of the sweet potato seedlings. The action has defects such as long clamping time of sweet potato seedlings, long transfer distance, and easy bending damage of sweet potato seedlings, which will greatly reduce the survival rate of sweet ...

[0002] The transplanting mechanism of the existing sweet potato seedling transplanting machine is such as the Chinese utility model patent "authorized announcement number: CN211861070U; authorized announcement date: November 06, 2020; name: a new type of sweet potato seedling wheel-type seedling delivery mechanism". It shows that after the clamping part of the clamping mechanism clamps the front end of the sweet potato seedlings, it needs to move backward horizontally for a long distance, and then move downwards to realize the planting operation of the sweet potato seedlings. The action has defects such as long clamping time of sweet potato seedlings, long transfer distance, and easy bending damage of sweet potato seedlings, which will greatly reduce the survival rate of sweet potato seedlings

In addition, the clamping mechanism is driven by a four-bar mechanism, and the four-bar mechanism for driving the clamping mechanism is set on one side of the clamping part. , the four-bar mechanism needs to use point D as the rotating shaft to drive the rod body between point C and point D to make a circular swing. The four-bar mechanism can only be driven by the driving force of the rotating shaft at point D, and there is a required drive Disadvantages of large load and high energy consumption
