Automatic control cutter with overload protection function

Abstract

The invention discloses an automatic control cutter with an overload protection function. The problems of incapability of a cutter in complete cutting of concrete, no overload protection function of the cutter and the like are effectively solved. The automatic control cutter comprises a rack, and is characterized in that a bottom plate is hinged to the lower end of the rack, wherein electric pushrods are connected between the bottom plate and the rack; a first fixed frame and a second fixed frame are fixedly arranged on the inner lower part of the rack; a rotating shaft is arranged in the first and second fixed frames in a penetration manner; a mounting section of the which the diameter is smaller than that of the rotating shaft is arranged on the middle section of the rotating shaft; a shaft sleeve is arranged on the mounting section in a sleeving manner; a chain wheel is fixedly arranged outside the shaft sleeve, and is connected with an engine through a chain; a reset spring pressed against one end of the shaft sleeve is connected to the rotating shaft in the sleeving manner; a first groove is formed in the other end of the shaft sleeve; a steel ball is connected in the first groove through a spring; a second groove capable of accommodating the steel ball is formed in the rotating shaft. The automatic control cutter is simple and reasonable in structure, a cut road can be completely separated from an earth foundation to avoid secondary construction, and overload protection is added at the same time of cutting to prevent a cutting disk from being stressed, deformed and damaged.

Description

technical field [0001] The invention relates to the technical field of building and road construction equipment, in particular to an automatic control cutting machine with overload protection. Background technique [0002] With the development of transportation, concrete roads have been vigorously constructed in road construction, but the damage of concrete roads is quite serious, and the road management department needs to repair the roads. Usually, an impact hammer is used to divide the damaged pavement into a small piece of concrete, and then re-pour new concrete. This repair method is laborious, unevenly divided, and inefficient; there is also a cutting machine that sets the cutting depth at the rear of the machine frame. Adjust the screw rod, but the depth is not easy to grasp. The depth is preset each time, and it needs to be reset for different cutting depths next time, which is not convenient. However, the depth of the road is different. Using the preset depth may o...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an automatic control cutting machine with overload protection, which effectively solves the problem of overcutting of roads caused by the artificially set depth of the cutting machine during the cutting process. Problems such as incomplete cutting and cutting machine not equipped with overload protection can save construction time, speed up the construction progress, reduce the technical requirements of operators, protect the operators and the cutting machine itself, and make it more popular
