All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1 and 2, the utility model discloses a joint cutter for road construction, which comprises a cutting box 1, wherein the lower end of the cutting box 1 is provided with a roller 2, and the left side of the cutting box 1 is provided with a push rod 3; the cutting assembly is used for cutting a seam on a road surface and comprises a cutting blade 4 and a cutting motor 5 for controlling the cutting blade 4 to rotate; the lifting component controls the cutting component to lift; the lifting assembly comprises a first motor 6 which is arranged at the top of the cutting box 1; the threaded rod 7 is vertically arranged in the cutting box 1 and is controlled to rotate by the first motor 6, and the bottom of the threaded rod 7 is rotationally connected with the cutting box 1 through a bearing; the screw sleeve 8 is sleeved on the threaded rod 7 and is in threaded connection with the threaded rod 7; the limiting rod 9 is arranged in parallel with the threaded rod 7 and penetrates through the threaded sleeve 8 to be in sliding connection with the threaded sleeve 8; the mounting rack 10 is fixedly connected with the threaded sleeve 8, and the cutting blade 4 and the cutting motor 5 are both mounted on the mounting rack 10; the bottom of the cutting box 1 is provided with a cutting opening 11 for the bottom of the cutting blade 4 to pass through; the device also comprises an air blowing mechanism, wherein the air blowing mechanism comprises a pressing plate 12 which is horizontally arranged, and one end of the air blowing mechanism is fixed on the right side of the mounting rack 10; the corrugated pipe 13 is provided with an air cavity 14, the top of the corrugated pipe is fixedly connected with the pressing plate 12, and the bottom of the corrugated pipe is fixedly connected with the bottom wall of the cutting box 1; and the air nozzle 16 is fixed on the right side of the cutting box 1 and is communicated with the air cavity of the corrugated pipe 13 through an air flow pipe 15, and the air nozzle 16 is arranged in a downward inclined mode.

When using, promote the push rod and will cut the case and push away to treating joint-cutting department, then start first motor, it rotates to drive the threaded rod, because the restriction swivel nut that receives the gag lever post can't rotate along with the threaded rod, so the swivel nut descends along with the rotation of threaded rod, drive the cutting blade decline on mounting bracket and the mounting bracket, and start cutting motor and rotate drive cutting blade, along with cutting blade's decline cuts the road surface, and will promote certain distance forward, accomplish joint-cutting work, first motor reversal drives swivel nut and cutting area rise partially after the joint-cutting is accomplished, it carries out the joint-cutting to next joint-cutting department to move.

Meanwhile, the clamp plate rises along with one when the mounting bracket rises, drive the bellows extension, the air enters into the air cavity through the air current pipe from the air cock, the gaseous increase of air cavity in the bellows, when the cutting, swivel nut and mounting bracket descend, the clamp plate descends along with it and pushes the bellows downwards, the gas in the air cavity is pushed out and is followed the nozzle blowout through the air current pipe, the spun gas blows the road surface on cutting box right side, will treat that the dust sand grain on the road surface of joint cutting department blows away, then promote the cutting box again and carry out joint cutting work to the road surface after the clearance, because nozzle spun gas can't blow away the impurity in the distance, so this joint cutting machine is comparatively fit for the joint cutting work of short distance, of course this joint cutting machine also can carry out long distance joint cutting, still have the cleaning effect, it is relatively poor only to clean up the joint cutting work of the short distance of effect.

Through above-mentioned technical scheme, through the lift work of the transmission control cutting blade of threaded rod and swivel nut, the transmission is stable, improves the stability of joint-cutting work, through the setting of the mechanism of blowing, when control cutting blade goes up and down to carry out the joint-cutting, treats the road surface of joint-cutting and blows the clearance, blows away the impurity of treating joint-cutting department, guarantees the stability of joint-cutting work, extension cutting blade's life.

In this embodiment, the one end that mounting bracket 10 was kept away from to swivel nut 8 is fixed with sighting rod 17, sighting rod 17 wears out cutting case 1, the spout that supplies the sighting rod to reciprocate is seted up to the correspondence on the 1 lateral wall of cutting case.

In this embodiment, the side wall of the cutting box 1 is provided with a scale on one side of the chute.

Through above-mentioned technical scheme, when the swivel nut drove cutting blade and descends when cutting, the sighting rod descends along with cutting blade in the lump, and the cutting depth of understanding cutting blade that can be directly perceived conveniently reads the lift distance through the scale simultaneously, is convenient for control cutting height, the stability of packing joint-cutting work.

Example 2

As shown in fig. 3, the present embodiment is different from the above embodiments in that: in the embodiment, a cleaning mechanism is arranged on the right side of the cutting box 1, and the cleaning mechanism comprises a cleaning box 18 fixed on the right side of the cutting box 1; a second motor 19 mounted on the rights case; a rotating drum 20 which is arranged in the cleaning box 18 and is controlled by a second motor 19 to rotate; the drum 20 is provided with bristles 21.

Through above-mentioned technical scheme, at the during operation, start the second motor and drive the rotation and rotate, the stone impurity that the joint-cutting department will be treated to the pivoted brush hair promotes to the right side, clears up and falls to treat the great impurity of joint-cutting department, further improves the clearance effect, guarantees cutting blade's stable joint-cutting work.

In this embodiment, an illumination lamp 22 is installed at the right side of the cleaning box 18, and the cleaning box can work in a dark environment through the arrangement of the illumination lamp.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
