Description

Technical Field

[0001] The utility model relates to the technical field of material lifting, in particular to a miscellaneous lifting device. Background Art

[0002] The debris elevator is a device that transports the unthreshed grain debris during the harvesting process. It is a key component of the combine harvester in agricultural machinery and can reduce the grain threshing loss rate. The debris elevator usually includes a closed cylinder, in which a scraper chain conveyor belt is installed. The scraper chain conveyor belt conveys the grain debris and other materials vertically. This structural design enables the debris elevator to form an effective material circulation system inside the harvester, minimizing grain loss.

[0003] In order to facilitate transportation, the existing cylinder body is usually designed as a split structure, with the upper cylinder sleeved on the outside of the lower cylinder or the lower cylinder sleeved on the outside of the upper cylinder. However, this type of structural form of the miscellaneous elevator has the following problems: during the circulation and lifting of the scraper chain conveyor belt in the cylinder body, the edge of the scraper chain is easy to collide with the inner wall of the upper cylinder or the lower cylinder located inside according to the running direction, causing the chain to easily wear at the connection between the upper and lower cylinders, which not only generates noise but also shortens the life of the chain. Summary of the invention

[0004] The utility model aims to solve the problem that during the use of the existing debris elevator, the scraper chain is prone to hit the cylinder wall at the connection between the upper and lower cylinder sections, causing wear. A debris elevator is provided to avoid severe collision between the scraper chain and the cylinder wall while ensuring the connection strength between the upper and lower cylinder sections, thereby reducing the damage to the scraper chain.
