Abstract

The invention provides a tensioning mechanism for a seedling clamping convey chain. In the mechanism, two U-shaped frames, two tension springs, two tension shafts, two tension shaft sleeves, two tension adjusting nuts, a tension wheel support plate and two tension wheels are arranged on a movable frame in sequence. The tensioning mechanism is characterized in that each set of the tensioning mechanism consists of two U-shaped frames, two tension springs, two tension shafts, two tension shaft sleeves, two tension adjusting nuts, a tension wheel support plate, two tension wheels and the like which are sequentially arranged on the movable frame; and a process for adjusting the tensile force and tension stroke is that: the two tension adjusting nuts are rotated clockwise or counterclockwise along the direction of the tension shaft sleeves, wherein clockwise rotation means increase, while counterclockwise rotation means reduction.

Description

technical field [0001] The invention belongs to the technical field of peanut combine harvester accessories, and relates to a tensioning mechanism for seedling-clamping and transporting chains. Background technique [0002] The traditional tensioning mechanism has large volume, small tensioning force, small tensioning stroke and inconvenient installation. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a new type of tensioning mechanism, which has the advantages of compact structure, small volume, convenient installation, large tension force and large tension stroke. [0004] The technical solution adopted by the present invention to solve the technical problem is: on the movable frame of the peanut combine harvester, the tensioning part of the seedling-clamping conveying chain is installed to set and install two sets of left-right symmetrical tensioning mechanisms separated by a certain distance. T...
