However, during the assembly process, the gasket sleeve has no effective centering positioning on the thread and the assembly is easily biased by the action of gravity. After the bias, the contact surface between the oil bolt, the joint ball head and the oil bottom is not sealed, resulting in oil leakage
[0003] During the assembly process, the gasket sleeve has no effective centering positioning on the thread and the assembly is easily biased by the action of gravity. After the bias, the contact surface between the oil bolt and the joint ball head and the oil bottom is not sealed, so it is easy to cause oil leakage. According to the results of feedback from the market, the current structural failure rate has reached 0.2%, and our goal is ≤0.1%

The invention relates to an engine oil draining rubber tube and oil pan sealing structure for a grain combine. The engine oil draining rubber tube and oil pan sealing structure comprises an oil draining rubber tube assembly, a clamping-sleeve type direction-adjustable end elbow pipe joint assembly and an oil pan, wherein the oil draining rubber tube assembly comprises a rubber tube, a sleeve, a lining tube, a steel tube, a nut and a clamping sleeve, the nut and the clamping sleeve are arranged on the steel tube in a sleeving mode, the steel tube is welded to the lining tube, and the rubber tube and the lining tube are fastened through the sleeve; the clamping-sleeve type direction-adjustable end elbow pipe joint assembly comprises a joint body, a nut, a gasket and an O-shaped ring, and the direction-adjusting end of the joint body is sleeved with the gasket and the O-shaped ring and fastened through the nut; the oil draining rubber tube is connected with the joint, and the joint is connected with the oil pan; and the oil draining rubber tube and the joint body are sealed through the clamping sleeve, and the joint body and the oil pan are sealed through the O-shaped ring. Compared with traditional structures, an oil passing bolt, a sphere oil passing joint and a composite gasket are omitted, and the problem that the composite gasket deflects due to gravity and non-effective center-aligning positioning of a threaded section in the assembling process, a sealing face has no sealing effect, and oil leaks is solved.
Description
technical field [0001] The invention belongs to the technical field of grain combine harvester design, in particular to an oil drain hose and oil pan sealing structure for a grain combine harvester. Background technique [0002] At present, due to the structural limitation of the grain combine harvester, a long rubber hose needs to be added to the oil drain of the engine oil pan to facilitate the user to change the engine oil. In the current structure, the oil discharge hose passes through the ball head oil joint and the oil bolt, and composite gaskets are added at both ends for sealing. However, during the assembly process, the gasket sleeve has no effective centering positioning on the thread and the assembly is easily biased by the action of gravity. After the bias, the contact surface between the oil bolt, the joint ball head and the oil bottom is not sealed, resulting in oil leakage. [0003] During the assembly process, the gasket sleeve has no effective centering pos...
