Description

Technical Field

[0001] This utility model relates to the field of harvesters, specifically to an advanced harvesting and drying platform device. Background Technology

[0002] In agricultural harvesting machinery, the cutting and drying platform is a key component, and its performance directly affects harvesting efficiency and work quality. Existing cutting and drying platforms have significant shortcomings in their canvas belt tensioning devices and reel structures: traditional canvas belt tensioning methods are rigid and lack cushioning design, resulting in high resistance during operation. When grass is caught, the canvas belt is prone to excessive wear, shortening its service life and causing frequent malfunctions. Meanwhile, during operation, the reel's teeth easily become entangled in weeds, affecting reeling efficiency. Furthermore, some structural components lack strength, and maintenance and disassembly are inconvenient, restricting the stability and practicality of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide an advanced drying platform device.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An advanced harvesting and drying platform device includes a canvas belt stretching device and a reel tipping device. The reel tipping device includes a reel, which comprises an eccentric disc, a transmission device, long and short swing arms, a main disc assembly line, a toothed rake tube, a reel sub-disc, a reel main tube, and an end shaft. The toothed rake tube is equipped with main steel spring teeth, secondary steel spring teeth, and several spring teeth. The eccentric disc and the reel sub-disc are rotatably connected. The transmission device is rotatably connected to the eccentric disc. The toothed rake tube and the reel sub-disc are fixedly connected. The main reel and the auxiliary reel are fixedly connected; the end shaft is fixedly connected to the main reel; the canvas belt stretching device includes a conveying frame, an arc-shaped support plate, a stretching roller, a connecting support plate, a drive roller, a support plate, and a stretching triangle plate; the conveying frame, the arc-shaped support plate, the connecting support plate, the support plate, the stretching triangle plate, and the stretching roller support arm are all fixedly connected; the stretching roller is rotatably connected to the stretching roller support arm, the drive roller is rotatably connected to the stretching roller support arm, and the drive roller is also provided with a drive roller shaft head.

[0006] Preferably, the transmission device is further provided with a sprocket or a gear.

[0007] Preferably, the spring teeth are nylon spring teeth or steel spring teeth. Beneficial effects

[0008] This device utilizes the elasticity of the spring bow plate to effectively address the resistance of the canvas belt during operation and the cushioning effect when it catches grass, thereby increasing the service life of the canvas belt. This extends the service life of the canvas belt and reduces the failure rate. It uses the principle of long and short swing arms rotating within an elliptical eccentric disc to change the angle of the spring teeth. Each spring tooth flips when it returns to the top, throwing off the grass tangled on the rake tube and ensuring that the rake tube is always free of weeds. Attached Figure Description
