[0002] Tractor is the key mechanical equipment indispensable to modern agriculture, through introducing tractor and other modernization machinery, agricultural production changes from traditional, dependent on manpower mode to mechanization, automation mode. This change reduces manpower investment, improves operation speed and quality, promotes the development of agriculture to modernization, scientific and technological direction. It not only represents the improvement of agricultural mechanization level, also greatly improves the efficiency and yield of agricultural production.

[0003] Tractor hoist is the key mechanism of tractor operation, is the key mechanism of controlling agricultural implements (such as plough, seeding machine, harvester etc.). Its normal operation is crucial for ensuring the contact of agricultural implements and ground, adjusting operation depth, realizing automatic operation etc.

[0004] Tractor hoist is mainly composed of oil cylinder and pull rod two parts, oil cylinder is the power supply component, realizes reciprocating motion through the pressure change of internal hydraulic oil, and pull rod is connected with oil cylinder and agricultural implement, when the hydraulic oil in oil cylinder is subjected to pressure, push rod moves forward or backward, thereby driving pull rod to ascend or descend, and the motion of oil cylinder is converted into the lifting action of agricultural implement, and this reciprocating motion enables agricultural implement to be adjusted according to operation demand.

[0005] Tractor hoist is installed on tractor through mounting seat, and the existing mounting seat is generally composed of a plurality of fixed plates welded, and the welding seam is relatively concentrated, and due to the fact that tractor often needs to be operated in various complex operations, such as starting, accelerating, turning, climbing, etc., these operations will bring huge impact and vibration to oil cylinder mounting seat. Under the action of impact and vibration, stress concentration phenomenon is prone to occur at the welding seam on the oil cylinder mounting seat, if cracking occurs at the welding seam, not only the normal work of tractor hoist will be affected, but also the agricultural implement may be dropped or out of control, thereby causing security risks to agricultural production.
