Abstract

The invention relates to a new chipper machine which features that: square framework made up of vertical pole and cross beam covering with dust shed, air driller is fixed on back beam by bar clasp, driller pole connecting sleeve is perpendicular to ground and inserted with chipper pole, chipper plate, chipper plate made of hardening alloy layer of which the alloy layer surface contacts with ground, horizontal pneumatic cooling water tank is fixed on the top of framework by bar clasp with water inlet port on the top, air inlet port, safety valve, and water supply valve on the bottom stretching to back of framework top beam forming a handle, rubber damping tube is set at the end of the handle, fore rolling wheel is installed at the base of fore vertical pole in correspond to a universal wheel landing chassis hinged on back vertical pole consisting of landing chassis, spring, support pork and universal wheel. The invention is of rational structure, light and high efficiency without mill dust pollution and very convenience.

Description

technical field [0001] The invention relates to a roughening device for concrete surfaces in construction machinery, and is particularly suitable for a kind of roughening machine which replaces heavy manual work with machinery. Background technique [0002] In the construction of construction projects, especially in high and low-speed highways, bridges, overpasses, culverts, and slab projects, it is often necessary to pour again on the smooth surface of concrete products that have been poured. In order to improve the attachment of new and old concrete surfaces Focus on, first of all, gouging the smooth surface of the concrete that has been poured. In layman's terms, it is to roughen the smooth surface of the concrete to improve the grip of the concrete surface, especially in recent years. The formwork is easy to form the surface slurry, and the surface of the concrete product is smoother; at present, in the construction industry, the rough treatment of the concrete surface i...

[0002] In the construction of construction projects, especially in high and low-speed highways, bridges, overpasses, culverts, and slab projects, it is often necessary to pour again on the smooth surface of concrete products that have been poured. In order to improve the attachment of new and old concrete surfaces Focus on, first of all, gouging the smooth surface of the concrete that has been poured. In layman's terms, it is to roughen the smooth surface of the concrete to improve the grip of the concrete surface, especially in recent years. The formwork is easy to form the surface slurry, and the surface of the concrete product is smoother; at present, in the construction industry, the rough treatment of the concrete surface is still done manually, and the operator usually uses a steel drill and a hand hammer to grind the concrete surface. The surface is hammered and chiseled, and pits of different sizes and sizes are chiseled to make the surface rough. Each person can only chisel a few square meters per day. The technology is backward, dust pollution, labor intensity is high, production efficiency is low, and the quality of chiseling Irregularity, it is difficult to meet the rough treatment requirements for the smooth surface of the concrete; in order to reduce the weight of benzene, manual labor or chiseling with picks or sandblasting, but the effect is not great; Hair, but brushing cannot fundamentally eliminate the hazards caused by the concrete surface slurry, nor can it guarantee the quality of construction
