Description

Technical Field

[0001] This utility model relates to the field of tensioner structure technology, and in particular to a tensioner structure for agricultural machinery belts. Background Technology

[0002] In the field of agricultural machinery, belt drive systems are widely used in various agricultural equipment, such as tractors and harvesters, to transmit power and motion. As a key component in belt drive, the tensioner pulley's main function is to maintain the proper tension of the belt, prevent slippage, detachment, or excessive wear, thereby ensuring transmission efficiency and operational reliability.

[0003] Existing agricultural machinery belt tensioner structures mostly adopt traditional fixed or simple adjustable designs. Common solutions include support plate structures fixed by bolts or manual fine-tuning mechanisms based on screws. For example, fixed tensioners mount the support plate to the frame by welding or rigid connection. The structure is simple and low-cost, but it lacks flexibility and cannot adapt to changes in belt thickness or width. When changing belts of different specifications, the machine must be stopped to disassemble and reinstall the tensioner. This is not only cumbersome, time-consuming, and labor-intensive, but also prone to uneven belt tension due to improper adjustment, leading to slippage, increased noise, or premature wear. It also increases maintenance costs and may even affect the overall performance of the machine. Therefore, improvements are needed. Utility Model Content
