Description

Technical Field

[0001] This utility model relates to the field of cotton harvesting technology, specifically to a portable handheld cotton harvester. Background Technology

[0002] The existing portable cotton harvester works by using a continuously rotating, spiked conveyor belt at the collection port of the handheld harvesting unit to hook cotton near the collection port, pulling it off the cotton plant and rolling it into the harvesting unit. An internal baffle then removes the cotton ball from the conveyor belt, causing it to fall into a channel connected to a collection bag below, completing the automatic and easy collection process. Another type of portable handheld cotton harvester uses solar power, requiring the user to carry a backpack equipped with solar panels and a solar-to-electricity converter to address the inconvenience of a lack of stable charging infrastructure in the area.

[0003] Existing handheld cotton harvesters are mostly basic applications with simple structures, lacking attention to user experience. With the handle angled towards the ground and internal components and center of gravity concentrated at the front, users must exert force similar to activities like fishing, requiring wrist strength to pry the weight of the head, which can cause wrist damage with prolonged use. Furthermore, existing products are primarily powered by either large rechargeable batteries or solar panels. The former is too heavy, making prolonged bending and harvesting difficult; the latter is also bulky and highly dependent on weather conditions, resulting in unstable power supply, and also requires carrying heavy batteries to store the collected solar energy. Therefore, existing portable handheld cotton harvesters fail to consider the impact of user posture, usage time on comfort, and portability. Utility Model Content
