[0002] The flexible agricultural machinery drive shaft is a high-speed, low-support rotating body in agricultural machinery and equipment. After the cutting process is completed, the flexible agricultural machinery drive shaft needs to be medium-frequency quenched to improve the structural strength and toughness of the drive shaft, and improve its service life and wear resistance.

[0003] For example, CN109609748A discloses an automatic feeding device for heat treatment of a transmission shaft, the main points of its technical solution are: it includes a medium frequency quenching machine, an arm-type robot for clamping the transmission shaft is arranged next to the medium frequency quenching machine, and an automatic feeder and a material box are arranged in the working area of ​​the arm-type robot; it mainly arranges a material box positioning device, which is convenient for the robot to discharge the material after the processing is completed, and the accuracy of the discharge is guaranteed by automatically moving the position, so as to prevent the transmission shaft from rolling and colliding, thereby preventing the transmission shaft from being damaged.

[0004] The above-mentioned heat treatment device for processing flexible agricultural machinery drive shafts still has certain shortcomings: since high temperature will be generated inside the heat treatment device, once the staff takes and places the drive shaft, they will come into contact with the generated hot steam, which will cause the staff to be scalded, thereby posing a safety hazard to the device.

[0007] Among them, the bottom end of the quenching furnace body is fixedly connected with four supporting legs in a rectangular array, and the top end of the quenching furnace body is fixedly connected with two protective strips symmetrically along the center, and the material of the protective strips is a rubber component.

[0008] Among them, two hinges are detachably installed on one side of the front side of the quenching furnace body in a symmetrical manner along the center, and a box door is detachably installed on the side wall of the hinge.

[0009] A door handle is welded on one side of the front of the box door, and the cross-sectional area of ​​the box door is larger than the cross-sectional area of ​​the containing box.

[0010] There are two stabilizing plates, which are respectively located at the upper and lower ends of the containing box.

[0011] The pressure-resistant component includes a connecting base and a limiting telescopic rod, the upper surface of the connecting base is fixedly connected to the limiting telescopic rod, and the lower surface of the connecting base is connected to one side of the upper surface of the control box.

When the top of the control box is about to be squeezed by external force, the pressure-resistant component arranged on the top of the control box will work, and then the protective plate will contact the object instead of the top of the control box, and transfer the external force to the buffer spring and the limiting telescopic rod. When the buffer spring is acted on, the buffer spring will reduce the external force, thereby ensuring that the top of the control box will not be deformed. BRIEF DESCRIPTION OF THE DRAWINGS

The side wall of the hinge 12 is detachably installed with a box door 13, and a door handle 14 is welded on one side of the front of the box door 13. The cross-sectional area of ​​the box door 13 is larger than the cross-sectional area of ​​the containing box 5. There are two stabilizing plates 4, and the two stabilizing plates 4 are respectively located at the upper and lower ends of the containing box 5. The pressure-resistant component 9 includes a connecting base 91 and a limiting telescopic rod 92. The upper surface of the connecting base 91 is fixedly connected with the limiting telescopic rod 92, and the lower surface of the connecting base 91 is connected to one side of the upper surface of the control box 6.
