A Breaking Pick for Municipal Roads Using Internal Expansion to Produce Extensible Cracks

Abstract

The invention discloses a crushing pick for municipal roads, being able to generate extensible cracks by means of internal expansion. The crushing pick structure comprises a body, a generator, an on-off switch, a handle, a pick head and a diameter-enlarging crushing device, and has the advantages that through the anti-splashing mechanism and the pick head counter-rotating action, the part of scattered stones produced when the pick head collides with the pavement are bounced from the four sides, unnecessary damage to the face of the operator in the first place can be avoided; at the same time,under the action of the thread lines arranged on the surface of the vertebral body of the barrier, the stones at the bottom of the road are quickly rubbed by the external force in the reverse direction to change from the stone slab with cracks to the broken stones; by using the mutual cooperation of the ejector bar and the pattern cam, cracking of the rock blocks in the bottom of the road is accelerated, and the cracks of the rock blocks in the bottom of the road are extended by using the triangular vertebrae of different sizes, and the crushing area is enlarged, and the crushing of the upperstone slab is easier by enlarging the crushing cracks of the stone slab in the bottom of the road; and the crushing of the rock blocks in the upper stone slab can be well carried out when the holes onthe sides are cut, and the time effectiveness of the road crushing is improved.

Description

technical field [0001] The invention relates to the field of tools for breaking municipal roads, more precisely, it relates to a breaking pick for municipal roads that uses internal expansion to generate extensible cracks. Background technique [0002] In the process of municipal road renovation, it is usually necessary to use crushing tools to break and repair the road section that needs to be repaired. For the situation where the road section is small and the surrounding road surface is narrow and large crushers cannot enter the site, municipal personnel need to hold a breaker pick Break the road surface to complete the repair of the entire road surface. However, during the crushing process, the operator needs to bend over and hold the breaker pick to complete the breakage of the road because the breaker pick is lower than 1.2m. Higher, when it collides with the road surface, it is easy to collide and bounce the broken stones on the road surface and cause damage to the ope...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a breaker for municipal roads that utilizes internal expansion to generate ductile cracks, so as to solve the problem of the prior art that the breaker is less than 1.2m in the process of breaking. The operator needs to bend over and hold the breaking pick to complete the breaking of the road surface. When the breaking pick is started, its speed is high, and the moment it hits the road surface, it is easy to collide with the broken stones on the road surface and cause damage to the operator's face. In addition, after the pavement is broken, its surface is more comprehensively broken and its inner bottom is still a whole, requiring the user to carry out multiple deep crushing, resulting in relatively low work efficiency and the defect that the inner bottom of the pavement is not completely broken
