Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, specifically a lifting-type sunshade for rice transplanters. Background Technology

[0002] In agricultural production, rice transplanters are key pieces of equipment in the rice planting process. However, transplanting operations usually take place in open paddy fields during the hot season, exposing operators to intense direct sunlight for extended periods. This continuous exposure not only easily leads to health risks such as heatstroke and sunburn, but also accelerates physical exhaustion and mental fatigue, severely impacting the comfort, continuity, and overall work efficiency of the operation. Therefore, to ensure operator health and improve the working experience, installing effective sunshades on rice transplanters to provide sun protection has become a common and necessary requirement.

[0003] Currently, most sunshade devices on rice transplanters are fixed structures, and their height and angle are usually not adjustable to meet actual needs. For example, they cannot adapt to changes in operator height or the sun's altitude at different times, resulting in poor shading or obstructed visibility. More importantly, existing sunshade designs primarily focus on blocking direct sunlight from above, lacking effective lateral protection against low-angle sunlight in the early morning and evening, as well as strong glare from the paddy field surface. This limited protection leaves the operator's sides, especially the face, neck, and arms, exposed to harmful ultraviolet radiation and strong light, failing to provide comprehensive sun protection and meet the practical needs for all-weather, multi-angle shading.

[0004] Based on this, a lifting-type rice transplanter sunshade is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
