Description

Technical Field

[0001] This utility model relates to a high-strength, wear-resistant agricultural machinery door hinge, belonging to the technical field of agricultural machinery components. Background Technology

[0002] Agricultural machinery operates in harsh environments, frequently exposed to mud, dust, and vibration. As a crucial component of agricultural machinery, the reliability of the hinges directly impacts the machinery's lifespan and safety.

[0003] Currently, most common agricultural machinery door hinges use traditional welding or riveting structures, which have the following shortcomings: 1. Insufficient strength: Welded or riveted joints are easily broken by external impacts, especially during agricultural machinery operations, when doors are frequently subjected to vibration and impact, leading to hinge damage.

[0004] 2. Poor wear resistance: During use, frequent opening and closing of the hinge will cause wear between the hinge shaft and the hinge seat, reducing the life of the hinge.

[0005] 3. Poor sealing: Traditional hinges have a simple structure and cannot effectively prevent mud, dust, etc. from entering the interior of agricultural machinery, affecting the normal operation of the machinery.

[0006] 4. Difficult to adjust: It is usually not adjustable after installation. If the door frame is deformed or the hinges are misaligned, it is difficult to adjust. Utility Model Content

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a high-strength and wear-resistant agricultural machinery door hinge, comprising a first hinge arm, a second hinge arm, and a hinge shaft; The first hinge arm includes a fixing part and a connecting part. The fixing part is used to fix it to the agricultural machinery door frame. The connecting part is connected to the fixing part through a rounded transition and is used to form a rotatable connection with the second hinge arm. The fixing part is provided with at least two countersunk holes for installing fixing bolts. The design of the countersunk holes allows the bolt heads to be embedded inside the hinge arm to avoid interference with external components. The second hinge arm includes a fixing part and a connecting part. The fixing part is used to fix it to the agricultural machinery door, and the connecting part is connected to the fixing part through a rounded transition to form a rotatable connection with the first hinge arm. The fixing part is provided with a reinforcing rib structure to improve the overall strength. The hinge shaft connects the first hinge arm and the second hinge arm to achieve rotation. Wear-resistant sleeves are provided at the connection points of the first hinge arm and the second hinge arm.

[0009] Furthermore, sealing rings are provided at both ends of the hinge shaft.

[0010] Furthermore, the first hinge arm and the second hinge arm are made of high-strength alloy steel, and their connection parts are designed as cylindrical hinge structures.

[0011] Furthermore, both the fixing part of the first hinge arm and the fixing part of the second hinge arm are provided with at least two fixing holes, which can ensure the fixing effect in multiple directions.

[0012] Furthermore, the fixing hole is an eccentric bolt hole.

[0013] The beneficial effects of this utility model are: 1. High strength: Made of high-strength alloy steel and using a one-piece molding process, the hinge strength is significantly improved, enabling it to withstand vibrations and impacts during agricultural machinery operation.

[0014] 2. Wear resistance: The use of cylindrical hinge structure, carburized and quenched hinge shaft, self-lubricating wear-resistant sleeve and other measures effectively reduces hinge wear and extends service life.

[0015] 3. Good sealing performance: The use of sealing rings prevents dirt, dust and other contaminants from entering the hinge, ensuring the normal operation of the agricultural machinery.

[0016] 4. Easy to adjust: The position and gap of the door can be easily adjusted through the eccentric bolt holes to achieve precise alignment, facilitating installation and maintenance.

[0017] 5. The countersunk hole design ensures the embedding effect of the fixing bolts and reduces the risk of external force interference. Attached Figure Description
