Description

FIELD OF THE INVENTION[0001]The present invention belongs to the field of machinery, is especially suitable for the field of digging machinery or engineering machinery, and particularly relates to an efficient impact blanking digging method without material clamping and an efficient impact blanking digging machine without material clamping.BACKGROUND OF THE INVENTION[0002]The existing impact type digging impact mechanisms as punching and cutting digging equipment, impact heading equipment, bucket excavating equipment and the like is generally a double-layer impact mechanism or a multilayer impact mechanism. For the structural form of the double-layer or multilayer impact mechanism on the digging equipment, the structural forms of an inner-layer impact mechanism and an outer-layer impact mechanism are generally uniform structures or similar structures. Therefore, in a material impacting process of the impact mechanisms, a material clamped between the impact mechanisms cannot be disch...

AI Technical Summary

Benefits of technology

This patent describes a device for impacting a material wall to break its strength or to create a step shape. The device includes inner and outer layers of impact teeth that are designed to impact the material wall at certain angles. The device also includes a power box body and a breakage-proof impact actuator to prevent damage to the device during impact. The device also includes guiding rods to ensure proper alignment and stability during use. The technical effect of the patent is to provide a more efficient and precise device for impacting materials.

Problems solved by technology

Therefore, in a material impacting process of the impact mechanisms, a material clamped between the impact mechanisms cannot be discharged.

Namely, after being dug by the inner-layer impact mechanism close to a material layer, the material is clamped between the inner and outer-layer impact mechanisms and cannot be discharged, a material block failing to be discharged is extruded into broken materials, thus reducing the lump material rate of the produced material and increasing the operation resistance of the impact mechanisms, and the material block failing to be discharged causes break-off of the impact mechanisms to damage the application performance of the equipment and even prevent continuous production if the case is serious.
