[0002] In order to save resources, old steel drums used in the fields of chemical and petroleum need to be refurbished before being reused. The residues in the steel drums are toxic and hazardous substances. Currently, the end caps of the drums are cut manually, which is inefficient and poses great safety hazards. Even if mechanical cutting machines are used for cutting, the efficiency and quality of cutting the end caps of the drums cannot meet the actual production needs due to the uneven force between the blade and the drum and the poor cutting stability. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a cutting head for a cutting machine tool of a steel barrel cutting and dumping line.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A cutting head for a cutting machine tool of a steel barrel cutting and dumping line comprises a cutting assembly fixed on the machine tool, the cutting assembly comprising a motor, a turntable and a cutter head body, the turntable being mounted at one end of the motor, the cutter head body being mounted at one side of the turntable, the cutter head body comprising a base plate, a blade and a push rod, the base plate being fixed at one end of the turntable, a through hole being provided on the base plate for the push rod to move, a mounting sleeve being fixed at the periphery of the push rod, a plurality of sixth brackets being provided at the periphery of the mounting sleeve, a second movable cavity being provided on the sixth bracket, a plurality of first connecting rods being rotatably connected to the periphery of the base plate, an end of the first connecting rod being rotatably connected to a second connecting rod away from the base plate, the second connecting rod being arranged to pass through the second movable cavity and a tool holder being mounted at an end away from the first connecting rod, and the blade being fixed on the tool holder.

[0006] In the embodiment of the present invention, a first movable cavity is provided in the installation sleeve, a spring is provided in the second movable cavity, and the spring is sleeved on the outer circumference of the ejector rod.

[0007] In the embodiment of the present invention, the sixth bracket is provided with a third movable cavity, a side of the tool holder close to the sixth bracket is rotatably connected to a third connecting rod, and the third connecting rod is rotatably connected to the sixth bracket in the third movable cavity.

[0008] In an embodiment of the present invention, a striker is provided at one end of the push rod away from the mounting sleeve.

[0009] In the embodiment of the present invention, a bearing surface is provided on a side of the sixth bracket away from the mounting sleeve.

[0010] In the embodiment of the present invention, a side of the sixth bracket close to the top rod is provided with a surrounding surface.

[0011] The beneficial effects of the present invention are as follows: when in use, the motor drives the turntable to rotate, and the rotation of the turntable drives the base plate to rotate. After the base plate rotates, it drives the first connecting rod and the second connecting rod connected to the base plate to rotate, and then drives the tool holder to rotate.

[0022] The cutter head body 501 is installed on one side of the turntable 505, and the cutter head body 501 includes a base plate 5011, a blade 5022 and a push rod 5023. The base plate 5011 is fixed to one end of the turntable 505, and a through hole is provided on the base plate 5011 for the push rod 5023 to move. A mounting sleeve 5015 is fixed to the outer periphery of the push rod 5023, and a plurality of sixth brackets 5018 are provided on the outer periphery of the mounting sleeve 5015. A second movable cavity 5017 is provided on the sixth bracket 5018.
