Each first sliding block 6 is provided with a sliding groove 14 in the front-back direction, a second sliding block 15 is arranged in the sliding groove 14, a second pressure spring 16 is arranged between the second sliding block 15 and the rear end of the sliding groove 14, a vertical rod 17 penetrates through the second sliding block 15, the cutting blade 7 is fixed at the lower end of the vertical rod 17, an annular sleeve 18 is arranged on the vertical rod 17, a first locking screw 19 is arranged on the annular sleeve 18, a cross rod 20 is fixed at the rear side of the annular sleeve 18, an arc-shaped groove 21 positioned at the rear side of the sliding groove 14 is arranged on the first sliding block 6, the rear end of the cross rod 20 is arranged in the arc-shaped groove 21, when the cutting blade 7 is blocked by a hard object, the cutting blade 7 pushes the second slide block 15 to move backwards against the action of the second compression spring 16, thereby driving the rear end of the cross rod 20 to move backwards along the arc-shaped groove 21 and deflect to one side, and driving the vertical rod 17 and the cutting blade 7 to rotate for a certain angle to avoid hard objects.
The cutting blade 7 is wedge-shaped, and when the cutting blade 7 is blocked by a hard object, the blocking object can be pushed to one side more smoothly by matching with the rotation of the cutting blade 7.
Two cutting blade 7 in the outside all articulate at the montant 17 lower extreme that corresponds, and a second locking screw 22 is respectively installed to these two montant 17 lower extremes to make two cutting blade 7 in the outside all can rotate to the inboard and can lock at arbitrary angle, shovel board 12 be equipped with two kinds of types flat and trapezoidal cross sectional shape, cutting blade 7 in the outside rotates to the inboard and changes into the shovel board 12 back of trapezoidal cross section, can carry out the cutting and the excavation of trapezoidal slot.
The box 11 in install the cylinder 23 of a left and right directions, the circumference equipartition has a plurality of page or leaf boards 25 along the axial arrangement on the outer wall of cylinder 23, all be equipped with one row of spike tooth 24 of arranging on the outer wall of cylinder 23 along the axial between every two adjacent page or leaf boards 25, when cylinder 23 rotated, spike tooth 24 can smash the soil block that is big on shovel 12, page or leaf board 25 can stir the soil on shovel 12 to auger 10 lower port department to guarantee smooth soil discharging.
For guaranteeing cutting blade 7's stability, slide bar 5 around arranged two side by side, two slide bars 5 all pass a plurality of first sliders 6 and all fix on crane 3.
The box 11 be equipped with multiple model, box 111 installs at the auger 10 lower extreme through flange detachably to can follow the box 11 of changing different width models according to the fluting width.
Threaded rod 4, spiral auger 10 and cylinder 23 by driving motor drive, the construction car can be driven by driving motor drive also can be driven by the diesel engine.
When the invention is used, the nuts 9 at the two ends of the sliding rod 5 are adjusted according to the width of the ditch so as to adjust the span of the two outermost cutting blades 7, the span of the nuts 9 screwed inwards is reduced, otherwise, the span is increased, the span of the two outermost cutting blades 7 is equal to the width of the ditch, and the box body 11 is replaced by the same type as the width of the ditch.
The adjustment of cutting blade 7 is accomplished and box 11 is changed and is accomplished the back, make the construction car stride in the both sides of treating the ditch, two cutting blade 7 in the outside aim at the both sides wall position of ditch respectively, then start threaded rod 4's driving motor, threaded rod 4 drives crane 3 and descends, thereby make a plurality of cutting blade 7 insert underground to the bottom position of slot, then start the construction car and make the construction car form along the ditch trend, start simultaneously and draw pneumatic cylinder 13 to upwards promote the shovel board 12 rear end gradually to one side, thereby make shovel board 12 front end descend gradually and cut into underground to the ditch groove bottom degree of depth.
After the cutting blade 7 and the shovel plate 12 are both cut into the ground, when a construction vehicle runs forwards, the cutting blade 7 can firstly divide soil in the groove into a plurality of smaller parts, then the shovel plate 12 shovels the divided soil, and resistance of the shovel plate 12 can be greatly reduced after the soil is divided; soil in the groove enters the box body 11 along the shovel plate 12 and is conveyed to one side of the groove by the auger 10, and the spike teeth 24 and the page plates 25 on the roller 23 can stir the soil to an inlet of the auger 10 while crushing the bulk soil, so that the soil is discharged smoothly.
When cutting blade 7 runs into the stone, when hard things such as fragment of brick blockked, cutting blade 7 is hindered to promote second slider 15 and overcomes the effect rearward movement of second pressure spring 16, second slider 15 promotes horizontal pole 20 rearward movement, horizontal pole 20 rear end slides along arc wall 21 and can drive montant 17 through annular cover 18 and deflect, thereby make cutting blade 7 deflect, and cutting blade 7 is the wedge, as long as cutting blade 7 just can squeeze out the obstacle smoothly after deflecting, thereby make cutting blade 7 cross the obstacle, including connect by first pressure spring 8 between the first slider 6, the elasticity of first pressure spring 8 makes cutting blade 7 have certain activity allowance about, thereby can be better cross the obstacle.
When the trapezoidal groove needs to be excavated, the second locking screws 22 are loosened, the two outermost cutting blades 7 are rotated inwards to a required angle and then locked, the first locking screws 19 on the vertical rods 17 of the two outermost cutting blades 7 are loosened, the two outermost cutting blades 7 are adjusted downwards to enable the lower ends of the two outermost cutting blades 7 to be flush with the lower ends of the rest cutting blades 7, and then the first locking screws 19 are locked; after the cutting blade 7 is adjusted, the shovel plate 12 is replaced by the shovel plate 12 with the trapezoidal section with the corresponding width, and the groove can be excavated according to the construction steps.
The side wall of the groove body after excavation is cut by the cutting blade 7, the groove bottom is formed by scraping by the shovel plate 12, and the shovel plate 12 collects excavation, leveling and soil cleaning, so that the flatness of the side wall and the bottom of the groove body is good, soil materials in the groove body are completely discharged, the floating soil in the groove body is very little, leveling and soil cleaning are not needed, and the construction efficiency is greatly improved; in addition, the rotary grooving tool is not adopted, dust is not easy to raise, the noise is low, and the green construction concept is better met.
