Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0019] See also Figure 1-4 A movable conveying device for steel fiber casting material includes a hanging plate 1, the middle part of which is rotatably connected to a center hopper 3 through a slewing bearing 2, and the center hopper 3 can rotate around its own axis through the slewing bearing 2, and the outer side of the bottom end of the center hopper 3 is rotatably connected to a swing chute 4, and the top of the hanging plate 1 is provided with a casting material anti-blocking mechanism 5 located on one side of the center hopper 3, and three annular equidistantly distributed limiting mechanisms 6 are fixedly installed on the top of the hanging plate 1.

[0020] The limiting mechanism 6 includes a fixed seat 61 and an electric telescopic rod 62 fixedly mounted on the top of the hanging plate 1. The outer fixed sleeve of one end of the electric telescopic rod 62 is provided with a slide seat 63. The inner movable sleeve of the slide seat 63 has one end movably sleeved inside the fixed seat 61 and a push rod 64 with a handle on the outer side of the other end. The handle is used to manually push the push rod 64 and to adjust the length of the push rod 64 extending out of the slide seat 63. The inner rotation of the top of the slide seat 63 is connected to a screw rod 65 located on the inner side of the outer side of the push rod 64. By loosening the screw rod 65, the device can extend the push rod 64 according to the inner diameter of the furnace wall. The length of the slide 63 is adjusted so that the push rod 64 can be moved by the drive of the electric telescopic rod 62, and the limit mechanism 6 can be limited and fixed by the contact between the buffer pad 68 and the inner wall of the furnace wall. The bottom of the slide 63 is provided with a limit boss 66 adapted to the hanging plate 1. The slide 63 can be limited by the limit boss 66, so that the push rod 64 will not be offset during the movement, reducing the force acting on the telescopic rod of the electric telescopic rod 62. A limit plate 67 is provided at one end of the push rod 64 extending out of the fixed seat 61, and a buffer pad 68 is provided on one side of the limit plate 67.

Through the cooperation of the first spring 55 and the second spring 56, the vibration of the first fixed plate 53 can be buffered while ensuring that the first fixed plate 53 can reciprocate along the axial direction of the first fixed rod 51 and the second fixed rod 52 under the drive of the vibrator 57.

[0022] Among them, a limiting groove 7 adapted to the outer side of the bottom end of the screw rod 65 is opened on the outer side of the push rod 64. The push rod 64 can be limited by the cooperation between the screw rod 65 and the limiting groove 7, so that the push rod 64 will not rotate after the screw rod 65 is loosened, so that the push rod 64 can be pushed by the handle.

[0023] When the device is in use, the limit on the push rod 64 can be released by loosening the screw rod 65, and the push rod 64 is pushed by the handle while the length of the push rod 64 extending out of the slide 63 is adjusted according to the inner diameter of the furnace wall. The push rod 64 can be driven by the electric telescopic rod 62 to move through the slide 63, and the hanging plate 1 can be limited and fixed through the contact between the buffer pad 68 and the inner wall of the furnace wall, so that the hanging plate 1 can be stably suspended inside the furnace wall by the wire rope.
