Seedling transportation linkage mechanism of a core trough transplanter

Abstract

The invention relates to a seedling transport linkage mechanism of a core trough type transplanter, which belongs to the technical field of pot seedling transplanting equipment. It consists of a pot seedling carrying plate, a seedling drop tube, a telescopic device, a linkage shaft A and a linkage shaft B; one side of a plurality of seedling drop tubes is installed with a pot seedling carrying plate in an inclined shape through a support rod, and the pot seedling carrying plate and the falling seedling cylinder contact connection; the other side of the falling seedling cylinder is equipped with a linkage shaft A through the bearing seat, one end of the linkage shaft A is equipped with an incomplete gear, and the linkage shaft A inside the incomplete gear is equipped with a cam, and one side of the linkage shaft A passes through The bearing seat is equipped with a linkage shaft B, and one end of the linkage shaft B is equipped with a complete gear, and the complete gear is meshed with the incomplete gear; a telescopic device is installed between the linkage shaft A and the seedling tube through the installation frame A and the installation frame B . The seedling transport linkage mechanism works synchronously with the transplanting device of the transplanting machine, and can continuously transport the pot seedlings to the transplanting device to complete the transplanting of the pot seedlings, reduce the amount of manual labor, and improve the work efficiency of seedling throwing.

Description

technical field [0001] The invention relates to a seedling transport linkage mechanism of a core trough type transplanter, which belongs to the technical field of pot seedling transplanting equipment. Background technique [0002] my country is a large agricultural country. In agricultural production, compared with conventional seedling raising methods, pot seedlings have the characteristics of no root damage, high survival rate, and high yield. They have been widely used in cotton, rapeseed, tobacco and other crops. The pot seedling transplanting machine is mainly semi-automatic. In some existing transplanting equipment, the seedling throwing link cannot realize automatic seedling throwing, and the seedling throwing is usually done manually, that is, by sitting on the workbench of the equipment manually.

Problems solved by technology

[0002] my country is a large agricultural country. In agricultural production, compared with conventional seedling raising methods, pot seedlings have the characteristics of no root damage, high survival rate, and high yield. They have been widely used in cotton, rapeseed, tobacco and other crops. The pot seedling transplanting machine is mainly semi-automatic. In some existing transplanting equipment, the seedling throwing link cannot realize automatic seedling throwing, and the seedling throwing is usually done manually, that is, by sitting on the workbench of the equipment manually. Put the potted seedlings into the seedling tube one by one. This method has the problems of high labor intensity and low efficiency of seedling throwing operation; at the same time, the working method of manual seedling throwing often leads to seedling leakage due to unfixed time. Occurs, it needs to be artificially replenished in the later stage, and it is difficult to apply to the seedling operation of large-scale transplanting, so it is necessary to improve it
