Description

Technical Field

[0001] This utility model relates to the technical field of anti-grass entanglement device for corn header boxes, and in particular to an anti-grass entanglement device for corn header boxes. Background Technology

[0002] Corn stalks are highly resilient and often grow alongside weeds (such as grasses) in the field. During harvesting, the high-speed rotation of the stalk-pulling rollers can easily cause weeds and stems to get caught in the joint between the rollers and the gearbox. This entanglement can then compress bearings, gears, and other components, leading to blockages, deformation, or even breakage. Therefore, anti-entanglement devices are urgently needed to prevent weeds from getting tangled in the corn.

[0003] For example, in a class of prior art represented by application number CN201520754809.3, the main structure includes a frame, a stem-pulling roller, a gearbox, and an anti-tangle device. The anti-tangle device is a symmetrically arranged arc-shaped baffle located at the junction of the stem-pulling roller and the gearbox, and is installed and connected to the gearbox. This device can prevent damage to gearbox parts caused by weeds and stems, eliminate failures in the stem-pulling roller transmission parts, reduce the overall machine failure rate, lower maintenance costs, and improve the machine's economic efficiency.

[0004] During use, it was found that existing anti-weed entanglement devices may still allow weeds to enter during harvesting, and these weeds cannot be dealt with, causing the header box to become entangled with weeds. Therefore, there is an urgent need for an anti-weed entanglement device for corn header boxes. Utility Model Content
