Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a ground-mounted cotton picking roller. Background Technology
[0002] In cotton harvesting machinery, the ground-level cotton pickup roller is one of the core components, and its pickup brush structure directly affects pickup efficiency and work quality. Existing pickup rollers typically use a metal roller body with mounting grooves on its surface, into which a strip-shaped pickup brush is then fixed with bolts or clips. However, this structure has the following problems:
[0003] 1. The picking brush strips need to be aligned with the mounting slot one by one and tightened with bolts, which is inefficient and prone to loosening under vibration conditions, causing the picking brush to fall off or become misaligned.
[0004] 2. Replacing a damaged pickup brush requires disassembling multiple fasteners, which is time-consuming and labor-intensive, affecting the continuity of operations.
[0005] 3. Traditional mounting slot design restricts the fixing strength and arrangement density of the pickup brush, making it difficult to balance high durability and efficient pickup requirements.
[0006] To address the aforementioned issues, this technology proposes a novel pickup roller structure. By optimizing the pickup brush installation method and employing a modular quick-installation design or flexible interlocking groove, the pickup brush can be quickly installed and securely fixed, significantly improving assembly efficiency and reliability while reducing maintenance costs. This solution provides a more efficient and durable solution for picking up fallen cotton. Utility Model Content

[0009] As a preferred embodiment of the present invention, the pickup brush assembly includes a mounting base installed inside the mounting groove assembly, and the pickup brush is fixedly mounted on the upper end face of the mounting base.
[0010] As a preferred embodiment of this utility model, the mounting base is provided with a groove that mates with guide block A and guide block B, and a hole that mates with a pin.
[0011] As a preferred technical solution of this utility model, the mounting groove comprises a mounting groove fixedly installed on the periphery of the roller shaft, and the mounting groove is provided with guide block A and guide block B for fixing and guiding the mounting seat.
[0012] As a preferred technical solution of this utility model, the pickup brush is used to fix the position between the mounting base and the guide block B.
[0013] As a preferred embodiment of this utility model, the mounting base and the mounting groove are provided with mounting holes for fixing at the same positions.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model achieves precise positioning and rapid locking of the pickup brush through the cooperation structure of the guide block and pin shaft of the mounting base and the mounting groove, which greatly improves the assembly efficiency, facilitates maintenance and replacement, and reduces downtime.
[0016] 2.
