The utility model relates to a concrete joint cutter, which adopts a hydraulic cylinder lifting mechanism, does not need to cut an oblique frame, and the cutting disc automatically descends to cut when starting; the frame is provided with the direction adjusting mechanism, the direction of the front guide wheel of the frame can be adjusted through the handle, and the steering angle can be adjusted by utilizing the dial, so that the steering is more accurate, and the construction precision is favorably improved.

Description of the drawings:

fig. 1 is a schematic structural view relating to the present invention;

fig. 2 is a correlation diagram of the direction handle and the dial in the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model relates to a concrete joint cutter mainly has frame 1, cutting disc 2, frame 1 facial make-up is equipped with hoist mechanism 3, the cutting disc 2 is connected through bearing 31 to hoist mechanism 3 lower part, and hoist mechanism 3 is the preferred pneumatic cylinder. The cutting disc 2 is connected with the motor 21, the motor 21 is fixed below the lifting mechanism 3, namely, a frame plate extends to the side face below the lifting mechanism 3, the motor 21 is fixed on the frame plate, and the motor 21 can be connected with the speed reducing mechanism and passes through the bearing 31 through a shaft to be linked with the cutting disc 2.

The front end of the frame 1 is provided with a guide wheel 11, two sides of the rear end of the frame 1 are provided with pulleys 12 to form a three-wheel structure, the guide wheel 11 is provided with a guide wheel frame 4, the upper part of the guide wheel frame 4 can be connected with the frame 1 through a bearing, and the guide wheel frame 4 is linked with the guide wheel 11 through a shaft.

The rear end of the frame 1 is provided with a rotating ring 5, the lower part of the rotating ring 5 is respectively connected with the two sides of the guide wheel frame 4 through two sections of guide ropes 51, the rear end of the rotating ring 5 also comprises a direction handle 6, the lower end of the direction handle 6 is inserted into the rotating ring 5, when the direction handle 6 is rotated, the rotating ring 5 rotates towards one direction, and therefore the guide ropes 51 on the side are pulled, the guide wheel frame 4 is pulled, and the guide wheels 11 swing by corresponding angles. I.e. how many degrees the direction handle 6 is turned, the guide wheel 11 is turned the same angle.
