[0029] At least two guide wheels 4, the guide wheels 4 are arranged at intervals, and an annular guide groove is arranged on the guide wheels 4, and the steel is only connected to the inner wall of the guide groove.

[0030] Specifically, the steel is limited in the lower, left and right directions during transportation through the guide groove on the guide wheel 4, thereby restricting the shaking of the steel during shearing, reducing the knocking of the steel, and ensuring the smoothness of the outer surface of the steel. At the same time, the trough body 1 is hung and installed through the hanging mechanism, and the fixed connection structure is above, which has little influence on the base and track structure below, is convenient to adjust, effectively bridges the gap between the conveying track and the shearing machine, and reduces the bending of the steel.

[0031] In this embodiment, a gap for passing the steel is arranged between the guide wheel 4 and the bottom of the trough body 1, and the cross section of the guide groove is trapezoidal.

[0032] Specifically, the steel only contacts the inner side surface of the guide groove, avoiding friction and scratching with the trough body 1. The trapezoidal cross section is suitable for using round steel and square steel of different specifications.

[0033] Furthermore, the trapezoidal cross section has rounded corners to avoid scratching by sharp corners.

[0034] In this embodiment, the guide wheel 4 includes a 45# steel guide wheel or a tungsten carbide guide wheel.

[0035] Specifically, the material of the guide wheel 4 is 45# steel or tungsten carbide, which has a wear-resistant effect and avoids frequent replacement due to excessive wear.

[0037] A guide rail 2, the guide rail 2 is axially arranged at the upper end of the trough body 1;

[0038] A slider 3, the lower end of the slider 3 is slidably connected to the guide rail 2, and a telescopic rod is arranged at the upper end of the slider 3, and a clamp is arranged on the telescopic rod.

[0039] Specifically, it is connected and fixed through a clamp or other structures. The telescopic rod is convenient for adjusting the height of the trough body 1, so that the axes of steel of different specifications coincide with the shearing surface of the shearing machine. The guide rail 2 cooperates with the slider 3 to adjust the distance from the cutting edge, adapting to the use of steel with different cross-sectional sizes.

[0040] In this embodiment, the guide rail 2 is sheet-shaped, with both ends exposed outside the trough body 1, and a T-shaped groove matching the guide rail 2 is arranged on the slider 3.
