Description

Technical Field

[0001] This utility model belongs to the technical field of weed control fabric laying, and specifically relates to a weed control fabric laying device for tobacco furrows. Background Technology

[0002] In tobacco cultivation, laying weed control fabric (also known as ground cover or ground cover) is a widely used physical weed control and soil management method. This technology can effectively suppress weed growth, retain soil moisture, regulate soil temperature, and reduce soil erosion.

[0003] When encountering fields that are difficult for machinery to access or are small in size, the industry commonly uses a purely manual method for laying weed control fabric. The typical operating procedure is as follows: A worker (usually called the "roller") maintains a bent-over posture, holding the two ends of the weed control fabric roll with both hands. The worker walks backward to slowly rotate the roll, gradually releasing and unfolding the weed control fabric from its rolled state into a flat shape, thus achieving the purpose of laying the weed control fabric. However, this laying method requires the worker to maintain a bent-over posture for a long time, and the hands also need to apply rotational force for a long time, which can easily cause damage to the worker's waist and hands, and the labor intensity is high. Utility Model Content
