The specific working process of the invention is as follows: the device is integrally placed in a groove to be leveled when in use, so that an extending part and an inclined plate 19 of an edge part of a U-shaped scraper 9 are respectively contacted with the side wall of the groove and the ground and are extruded, at the moment, a motor is turned on, the motor drives two second gears 13 positioned at the rear side to rotate through a second chain wheel 15 and a first chain wheel 14, the synchronous rotation of the two second gears 13 is meshed with a first gear 12 to rotate so as to drive two vertical shafts 3 along the length direction of a support frame 1 to synchronously rotate, the two vertical shafts 3 arranged along the width direction of the support frame 1 are synchronously and reversely rotated by the rotation of the other second gear 13 meshed with the first gear 12 after the other second gear 13 is turned backwards, meanwhile, because the far rest ends of the cams 4 on the two vertical shafts 3 which synchronously and reversely rotate are symmetrical front and back, the far rest ends of the cams 4 on the two vertical shafts 3 arranged along the length direction are opposite in direction, when the cams 4 on the two vertical shafts 3 on the left side simultaneously press vertical shafts 5, the tight stop ends of the two cams 4 on the right side correspond to the vertical plate 5, so that the two pressing plates on the left side and the right side are alternately pressed and released, when the cams 4 rotate to press the vertical plate 5, the push stroke of the cams contacts with the vertical plate 5 to press the groove wall outwards by the vertical plate 5, at the moment, the telescopic rods 6 extend outwards and stretch the second tension springs 16 to enable the second tension springs to have a rebound tendency, the telescopic rods 6 provide support for the outward movement of the vertical plate 5, the push stroke extrusion enables the vertical plate 5 to contact and press the groove wall, at the moment, the far stop ends of the cams 4 press the vertical plate 5, as the far stop ends of the cams 4 are semicircular, at the moment, the vertical plate is extruded and cannot move, as the far stop ends of the semicircular cams 4 are pressed on a plane like driving wheels, at the support frame 1 moves forwards, at the moment, and as the vertical plate 5 is pressed and cannot move in the process, the movement of the support frame 1 can realize that the first tension springs 8 are stretched, when the return stroke of the cam 4 corresponds to the vertical plate 5, the vertical plate 5 is reset forwards under the reset action of the first tension spring 8 to catch up with the support frame 1, the left and right two groups of cams 4 are alternately compressed and loosened with the vertical plate 5, and the support frame 1 is provided with power at intervals so that the support frame 1 can move forwards uninterruptedly.

Support frame 1 drives runner 2 through the removal and rotates, simultaneously for U-shaped scraper blade 9 provides power, this power can effectual realization extension board and swash plate 19 scrape the dregs of slot lateral wall and bottom and through the deflector, swash plate 19 carries to conveyer belt 10 on, support frame 1's removal begins work through gyro wheel 20 drive conveyer belt 10, the L shaped plate of fixing on the conveyer belt 10 transports the dregs to the slot top, thereby dregs fall on falling V-shaped plate 11 and along the clear-out of the both sides realization dregs of slot when falling V-shaped plate 11 landing on falling V-shaped plate 11.

Compared with the traditional equipment, the device has the following advantages:

1. this device is through the end of stopping far away of cam 4 and the end of nearly stopping is alternative and extrusion riser 5, when the end extrusion contact riser 5 of far away stopping, cam 4 becomes the drive wheel, it directly changes the drive power of support frame 1 to rotate, realize the drive of support frame 1, when the return stroke of cam 4 corresponds with riser 5, riser 5 can not compress tightly the cell wall so the return stroke corresponds when riser 5, cam 4 idles on riser 5, realize under the reset action of first extension spring 8 that riser 5 is quick with support frame 1, two sets of cams 4 of extrusion riser 5 have alternately realized the continuous drive of support frame 1, also reset for riser 5 simultaneously and provide the essential time, make this device design reasonable high-efficient more.

2. This device passes through cam 4 extrusion riser 5, the riser 5 of both sides compresses tightly corresponding slot side wall, replace traditional drive wheel direct compression tank bottom to provide power, want to drive support frame 1 and remove and need very big torsion, if directly make the drive wheel effect at the tank bottom, support frame 1 must enough be heavy just be difficult to skid, there is the possibility that the slot was destroyed to the secondary like this, slot itself is narrow and dark simultaneously, it is difficult to realize to increase the counter weight, this device compresses tightly the tank wall from both sides, the necessary packing force when having satisfied for the drive wheel provides the drive, make it can not appear skidding in the drive process, this packing force implementation process need not be equipped with the counter weight simultaneously, effectual equipment loading that alleviates, convenient transport.

3. Uneven muck is scraped by the U-shaped scraper 9 and is conveyed to the upper part of the groove through the conveying belt 10, the inverted V-shaped plates 11 are dispersed to the two sides of the groove in the free falling process, muck removal is realized, and other power sources do not need to be installed for moving the power source supporting frame 1 in the removing process, so that the whole ditch leveling process is more complete and efficient.
