Forward-tilting prevention device of high-plant crop divider

Abstract

The invention provides a forward-tilting prevention device of a high-plant crop divider. The forward-tilting prevention device is arranged on the upper end face of the divider, wherein a driving chain wheel is connected to a cross beam, close to one side of the divider, at the front end of a rack through a chain wheel frame, and double-effect anti-winding covers are symmetrically arranged on the two sides of the driving chain wheel; a driven chain wheel is arranged at the position, close to the tip end, of the upper end face of the divider, and double-effect anti-winding covers are symmetrically arranged on the two sides of the driven chain wheel; a hemp clearing needle is arranged at the tip end of the divider through a hemp clearing needle fixing sleeve, and the needle tip faces the driven chain wheel; and a hemp pulling chain is installed between the driving chain wheel and the driven chain wheel, a tensioning wheel is arranged on the hemp pulling chain, hemp supporting pulling teeth are riveted to the hemp pulling chain, and hemp pulling chain anti-winding protection plates are arranged on the two sides of the hemp pulling chain. The forward-tilting prevention device solves the problem that when existing harvesting equipment is used for harvesting high-plant crops such as industrial hemp for fibers, in the dividing process of the divider, due to the fact that the plant height of the crops is high, the planting density is large in agriculture, tillers at the upper end are mutually hung and pulled, and crop stalks tilt forwards, the harvesting efficiency is improved, and the laying quality is improved.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to an anti-tilt device for a tall crop crop divider. Background technique [0002] For tall crops such as industrial hemp for fiber, the plant height is about 1-3 meters when harvested, and the planting density is 450 grains / m 2 , when existing harvesting equipment harvests tall crops such as industrial hemp for fiber, the crops to be harvested are separated from unharvested crops by the dividing device, and the tall crops to be harvested are pushed forward during the process of dividing Due to the high plant height of the crops and the relatively high planting density in agronomy, the tillers at the upper end hang on each other, making the crop stalks lean forward, which is not conducive to entering the cutter, affecting the cutting and laying effect, resulting in missed cutting and random cutting. shop and so on. Contents of the invention [0003] In view of the above-menti...
