[0002] An agricultural drive shaft is an important power transmission component in agricultural machinery, mainly used to connect a tractor and agricultural implements (such as a rotary tiller, a seeder, a harvester, etc.), and efficiently and stably transmit the power of the engine to the working device. It is characterized by being made of high-strength steel, having good torsional resistance and wear resistance, and usually being equipped with a telescopic protective sleeve on the outer layer to prevent dust and debris from entering. The agricultural drive shaft is flexibly designed to adapt to different working angles and terrains, and some models are also equipped with a safety clutch that automatically disconnects during overload to protect the equipment. It significantly improves the operation efficiency and reliability of agricultural machinery and is an indispensable key component in modern farm tillage.

[0003] The existing surface decarburization system and process for agricultural drive shafts with high torsional stiffness can specifically refer to the decarburization furnace with the publication number CN214840859U, which includes an upper furnace body, a middle section, and a lower cone body connected from top to bottom.

[0016] Preferably, based on the surface decarburization process of the high torsional stiffness agricultural transmission shaft, this process includes the following steps:

[0017] S1: Start the motor to drive the first driving roller and the conveyor belt to rotate. The conveyor belt drives the second driving wheel and the third rotating rod to rotate.

[0060] S3: The outer main body 18 of the gear pump is transported to the inside of the atomizing nozzle 31 through the first connecting pipe 29, so as to spray the surface of the transmission shaft to remove the oil film, and then the transmission shaft is transported to the inside of the decarburization device 41 through the conveyor belt 34 for decarburization.

[0061] S4: The collection hood 30 can collect the waste water and transport it to the inside of the collection box 44 through the collection pipe 42. When the waste water passes through the collection pipe 42, it will be filtered by the filter disk 51 and then flow into the collection box 44.

[0062] S5: The thrust of the second return spring 40 itself always applies a thrust to the sleeve block 37 and the third rotating rod 36 to the right. When the conveyor belt 34 is loose, the second return spring 40 will push the sleeve block 37 and the third rotating rod 36 to move to the right, and at the same time drive the slider 38 to move along the outside of the second guide rod 39, so as to ensure that the conveyor belt 34 is always in a taut state;

[0063] During operation, when the conveyor belt 34 is taut, the second return spring 40 is in a tightened state. When the conveyor belt 34 is loose, the second return spring 40 automatically rebounds and extends, and pushes the sleeve block 37 to move. When the sleeve block 37 moves, it drives the third rotating rod 36 to move at the same time, and the movement of the third rotating rod 36 drives the second transmission wheel 35 to move synchronously, so as to tighten the conveyor belt 34 again. At the same time, when the sleeve block 37 moves, it drives the slider 38 to move along the outside of the second guide rod 39.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.

The conveyor belt (34) drives the second driving wheel (35) and the third rotating rod (36) to rotate. The third rotating rod (36) rotates along the inside of the sleeve block (37). At the same time, the first driving roller (11) rotates to drive the first rotating rod (12) and the second driving disc (52) to rotate.

S5: The thrust of the second return spring (40) itself always applies a thrust to the sleeve block (37) and the third rotating rod (36) to the right. If the conveyor belt (34) is loose, the second return spring (40) will push the sleeve block (37) and the third rotating rod (36) to move to the right, and at the same time drive the sliding block (38) to move along the outside of the second guide rod (39), so as to ensure that the conveyor belt (34) is always in a taut state.
