DETAILED DESCRIPTION

[0027] Refer to Figures 1-4The utility model provides a kind of heading machine pick tooth seat, including tooth seat body 1, the inner wall sliding connection of tooth seat body 1 has pick tooth body 2, the lower surface of tooth seat body 1 is fixedly connected with baffle ring 3, the inner wall sliding connection of baffle ring 3 has two control blocks 5, two control blocks 5 mutually close one side is fixedly connected with pull rod 6, the end of pull rod 6 away from control block 5 is fixedly connected with limit block 4, limit block 4 is slidingly connected in the inner wall of pick tooth body 2, the lower surface of tooth seat body 1 is fixedly connected with mounting post 11, the surface of mounting post 11 is rotatably connected with mainboard 12, the lower surface of mainboard 12 is rotatably connected with first board 10, the lower surface of mainboard 12 is rotatably connected with second board 16. By setting mounting post 11, mainboard 12 can be connected to tooth seat body 1, mainboard 12 rotatably connected on the surface of mounting post 11, by setting mainboard 12, first board 10 and second board 16, two control blocks 5 synchronous movement can be conveniently controlled.

[0028] The overall specific setting and effect will be described below.

[0029] Referring to Figures 1-5 In the embodiment, the side of the two control blocks 5 away from each other is fixedly connected with a first bent rod 7 and a second bent rod 13, respectively. By setting the first bent rod 7 and the second bent rod 13, the position of the control block 5 can be adjusted conveniently. The side of the first bent rod 7 close to the first board 10 is fixedly connected with a first moving rod 8, and the side of the second bent rod 13 close to the second board 16 is fixedly connected with a second moving rod 14. By setting the first moving rod 8 and the second moving rod 14, the first board 10 and the first bent rod 7 and the second board 16 and the second bent rod 13 can be connected, so that the first board 10 or the second board 16 can be driven to rotate by the movement of the first bent rod 7 or the second bent rod 13.

[0030] The side of the first moving rod 8 close to the first board 10 is fixedly connected with a first fixed column 9, and the first fixed column 9 is slidingly connected to the inner wall of the first board 10. By setting the first fixed column 9, the first board 10 and the first moving rod 8 can be connected without affecting the rotation of the first board 10. The side of the second moving rod 14 close to the first fixed column 9 is fixedly connected with a second fixed column 15, and the second fixed column 15 is slidingly connected to the inner wall of the second board 16. By setting the second fixed column 15, the second board 16 and the second moving rod 14 can be connected without affecting the rotation of the second board 16. The surface of the first fixed column 9 and the second fixed column 15 is fixedly connected with two limit rings 17, and the four limit rings 17 are tightly attached to the first board 10 and the second board 16, respectively. By setting the limit ring 17, the first board 10 and the second board 16 can be stably connected with the first fixed column 9 and the second fixed column 15.

[0031] The working principle is that when the cutting tooth body 2 needs to be removed from the tooth seat body 1, the first bending rod 7 is pulled to drive the limiting block 4 to move away from the cutting tooth body 2 through the control block 5 and the pull rod 6, and the movement of the first bending rod 7 drives the first moving rod 8 to move, at this time, under the limitation of the mounting column 11 and the main plate 12, the first plate 10 rotates on the surface of the first fixed column 9, drives the main plate 12 to rotate, the rotation of the main plate 12 drives the second plate 16 to rotate on the surface of the second fixed column 15, and at the same time, the second moving rod 14 and the second bending rod 13 are moved through the second plate 16 and the second fixed column 15, so that the movement of the first bending rod 7 controls the two limiting blocks 4 to move away from the cutting tooth body 2 at the same time, the limitation of the cutting tooth body 2 is released, the cutting tooth body 2 is moved away from the blocking ring 3, and the disassembly of the cutting tooth body 2 is completed. By arranging the limiting ring 17, the stable connection between the first plate 10 and the second plate 16 and the first fixed column 9 and the second fixed column 15 can be ensured. By arranging the mounting column 11 and the main plate 12, the rotation and movement of the first plate 10 or the second plate 16 can drive the synchronous rotation and movement of the second plate 16 or the first plate 10, and then the first bending rod 7 and the second bending rod 13 are used to complete the simultaneous movement of the two control blocks 5, the complexity of disassembling and replacing the cutting tooth body 2 is reduced, and the efficiency of disassembling and replacing the cutting tooth body 2 is improved.
