Among them, the cutter head connecting shaft 115 is used for fixedly connecting with one end of the cutter bar 3, and one end of the cutter bar 3 is used for fixedly connecting with the cutter head 2.

The second eccentric turntable includes a second turntable bearing 109 and a second eccentric disk 108, and the second turntable bearing 109 and the second eccentric disk 108 are connected; a second eccentric shaft is provided on the second eccentric disk 108. Among them, a double-row cylindrical roller bearing 106 is provided between the first eccentric shaft and the second eccentric shaft. The first eccentric shaft and the second eccentric shaft are connected by the double-row cylindrical roller bearing 106. The suction pipe 118 passes through the axes of the first eccentric shaft, the second eccentric shaft, and the gear ring 111. The cutter head connecting shaft 115 is of a hollow structure (i.e., a suction cavity 119), and the suction pipe 118 is communicated with the cutter head connecting shaft 115.

[0032] More specifically, the first turntable bearing 104 adopts an external-tooth turntable bearing; the second turntable bearing 109 adopts a toothless turntable bearing.

[0033] More specifically, it further includes a driver seat; the driver seat includes a fixed bottom plate 113, a box body 110, a box cover 103, and an eccentric cover plate 114; the first eccentric turntable, the second eccentric turntable, and the planetary gear set are all arranged in the box body 110; one side of the fixed bottom plate 113 is fixedly connected with the box body 110 and the gear ring 111; the other side is provided with a connecting bearing; the fixed bottom plate 113 is connected with the eccentric cover plate 114 through the connecting bearing; the box cover 103 is fixedly connected with the box body 110; the driving motor 101 is connected with a driving gear 102, and the driving gear 102 is meshed and connected with the first eccentric turntable. Among them, the driving motor 101 is fixedly installed on the box cover 103; the rotating shaft of the driving motor 101 passes through the box cover 103 and is shaft-connected with the driving gear 102.

[0034] A material suction joint 120 and a joint mounting seat 116 are also fixedly installed on the box cover 103; the joint mounting seat 116 includes a connecting cavity 121; the material suction joint 120 is fixedly connected to the joint mounting seat 116, and both ends of the connecting cavity 121 are respectively communicated with the material suction joint 120 and the material suction pipe 118. Among them, the material suction joint 120 is used to connect an external aggregate device, so that a negative pressure for sucking remaining materials is generated in the connecting cavity 121, the material suction pipe 118 and the material suction cavity 119.

[0035] More specifically, it further includes: a material suction pipe mounting seat 117; the connecting cavity 121 is cylindrical; the material suction pipe mounting seat 117 is arranged in the connecting cavity 121, and the outer contour of the material suction pipe mounting seat 117 matches that of the connecting cavity 121; the material suction pipe mounting seat 117 is provided with a connecting hole 122; the material suction pipe 118 is fixedly connected to the material suction pipe mounting seat 117 and is communicated with the connecting cavity 121 through the connecting hole 122.

[0037] During operation, the driving motor 101 rotates, successively driving the first eccentric turntable, the second eccentric turntable, the planetary gear pair and the tool head connecting shaft 115 to rotate; among them, the second eccentric turntable drives the planetary gear pair to revolve. When the planetary gear pair revolves, the self-rotating gear 112 revolves along the gear ring 111. At the same time, since the gear ring 111 is meshed with the self-rotating gear 112, the self-rotating gear 112 is simultaneously driven to rotate in the direction opposite to the revolution, thereby driving the tool head connecting shaft 115 to perform a revolution and simultaneously complete a self-rotation, so that the tool head 2 connected to the tool head connecting shaft 115 forms a square cutting trajectory. On the other hand, the first eccentric turntable and the second eccentric turntable also simultaneously drive the material suction pipe 118 to revolve, and at the same time drive the material suction pipe mounting seat 117 to rotate in the connecting cavity 121. This structure can enable the material suction pipe 118 to still maintain communication with the material suction joint 120 during revolution, and continuously obtain the negative pressure for sucking remaining materials from the external aggregate device.

[0038] Further, in order to make the tool head 2 form a square cutting trajectory and realize full-section cutting of the material in the square crucible, the pitch circle diameter of the self-rotating gear 112 is 6 / 13 of the side length dimension of the inner cavity of the crucible; the eccentricity of each eccentric disc is 2.5 times the pitch circle radius of the self-rotating gear 112.

[0039] Furthermore, there are several driving motors 101; each driving motor 101 is provided with a corresponding driving gear 102; each driving gear 102 is respectively meshed with the first eccentric turntable, which can realize that multiple driving motors 101 provide power simultaneously to meet the need for large torque of various quality materials.
