[0017] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] To facilitate understanding of this embodiment, Figure 1 , Figure 2 , Figure 3 An ultra-high-speed crop shear disclosed in an embodiment of the utility model is introduced in detail.

[0019] Embodiment 1:

[0020] An ultra-high-speed crop shear comprises: a motor 1, a drum-type gear coupling 2, a flying shear box assembly 3, a flying shear 4, an electric swing arm 5, and a guide groove 6;

[0021] The motor 1 is provided with a drum-type gear coupling 2, which is pin-connected to the flying shear 4 through a flying shear box assembly 3. An electric swing arm 5 is installed on the front side of the flying shear 4, and a guide groove 6 is installed on the rear side of the flying shear 4. The flying shear 4 includes an upper shear head 401 and a lower shear head 402, and a shear blade 403 is installed between the upper shear head 401 and the lower shear head 402.

[0022] In this embodiment, if Figure 2 As shown, the front side of the shear is the left side of the flying shear 4, and the rear side of the shear is the right side of the flying shear 4; the flying shear box assembly 3 and the electric swing arm 5 are both arranged on a base.

[0023] Preferably, the maximum shearing section of the ultra-high-speed crop shear is φ22 mm, and the rolling speed v≤75 m / s.

[0024] In this embodiment, the drum-type gear coupling 2 is provided with two gears, including an upper shaft gear and a lower shaft gear. The upper shaft gear and the lower shaft gear are respectively provided with an upper shaft and a lower shaft. The upper shaft is connected to the upper shear head 401, and the lower shaft is connected to the lower shear head 402.

[0025] The working principle of the ultra-high speed crop shears provided in this embodiment is as follows:

[0026] The motor 1 drives the lower shaft gear through the drum-type gear coupling 2, and the lower shaft gear meshes with the upper shaft gear to drive the upper shaft and the lower shaft to rotate, thereby driving the upper shear head 401 and the lower shear head 402, and then driving the shear blade 403 to shear the rolled piece, the material of the rolled piece includes but is not limited to ordinary carbon steel, high-quality carbon structural steel, and low-alloy steel.

[0027] When the workpiece is trimmed, the electric swing arm 5 stops at the trimming position in advance. When the continuously operating flying shear 4 cuts off the head of the workpiece, the electric swing arm 5 quickly swings to the normal working position, so that the workpiece will enter the finishing mill along the guide groove 6.

[0028] When the tail of the rolled piece is to be cut, the electric swing arm 5 swings quickly to pull the rolled piece that has passed the steel position normally to the shearing position of the flying shear 4. After the continuously operating flying shear 4 shears the rolled piece, the electric swing arm 5 returns to the shearing position of the flying shear 4 and waits until the next cut of the rolled piece; when an accident occurs after the finishing mill, the electric swing arm 5 swings quickly and pulls the rolled piece to the breaking position of the flying shear 4, and the broken waste falls into the chute and is collected in the waste storage area; when the breaking work of the flying shear 4 is completed, the electric swing arm 5 waits at the shearing position of the flying shear 4 until the next cut of the rolled piece. Finally, it should be noted that the above-described embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited thereto. Although the utility model is described in detail with reference to the above-mentioned embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above-mentioned embodiments within the technical scope disclosed by the utility model, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the utility model, and should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
