The push stroke of the cam 9 is larger than the stroke of the connecting rod shaft diameter on the crankshaft 7 for driving the first connecting rod 8 to move, and meanwhile, the long gear 13 cannot be separated from the incomplete gear 12 when moving up and down.

The specific working process of the invention is as follows: when the device is used, the device is arranged at the bottom of a trench which is dug to be leveled, so that two polishing rollers 16 are arranged along the flow direction of the trench, the bottoms of two side plates 11 are close to two sides of the trench, the driving device is described by taking motor driving as an example in the using process, a driving motor is turned on at the moment, the motor drives a rotating shaft 2 to rotate through speed reduction, the rotation drives an incomplete gear 12 fixed on the motor and drives a crankshaft 7 to rotate through a first bevel gear 17 and a second bevel gear 18, and the crankshaft 7 drives a cam 9 to rotate while rotating.

When the rotating shaft 2 drives the crankshaft 7 to rotate, the rotation of the crankshaft 7 drives the two connecting rod shaft diameters on the crankshaft 7 to rotate, the first connecting rod 8 hinged on the connecting rod shaft diameters moves up and down when the connecting rod shaft diameters rotate, the up-and-down movement of the first connecting rod 8 drives the lower end of the piston rod 6 to move up and down through the piston cylinder 5, and the driving pressing plate 3 is driven to move up and down when the crankshaft 7 rotates in the process.

When the rotating shaft 2 drives the crankshaft 7 to rotate and simultaneously drives the cam 9 fixed on the crankshaft to rotate, the pushing range of the cam 9 is larger than the stroke of the first connecting rod 8, when the pushing range of the cam 9 moves to contact with the upper end baffle 27, the baffle 27 extrudes the upright post 26 to realize that the upright post 26 extrudes the inverted V-shaped structure through the lower end baffle 27, so that the inverted V-shaped structure is driven to push the two pressing plates 3 to move back to the two sides, at the moment, the two pressing plates 3 move back to back, the tension spring 19 is stretched, the two pressing plates have the tendency of resetting and the elastic potential energy, meanwhile, the second pressure spring 28 is extruded and has the tendency of rebounding and the elastic potential energy, in the process, the back movement of the pressing plates 3 can realize that the hinging position of the first connecting rod 8 and the connecting rod shaft diameter slides along the connecting rod shaft diameter, the sliding mode can be realized through a traditional lantern ring, meanwhile, the piston cylinder 5 can slide in the through groove 20, and, however, the pushing stroke of the cam 9 is larger than that of the first connecting rod 8, so that in the process, the downward extrusion effect of the inverted-V-shaped structure on the pressing plates 3 does not influence the pressing plates 3 towards two sides, when the return stroke of the cam 9 is contacted with the upper end baffle 27, the two pressing plates 3 can be reset towards the middle under the resetting effect of the tension spring 19, the upper end baffle 27 can be always attached to the cam 9 under the resetting effect of the second compression spring 28, the lower end baffle 27 can be always attached to the hinged position of the inverted-V-shaped structure, and the inverted-V-shaped structure is stressed to expand and contract to realize the left and right movement of the pressing plates 3.

When the rotating shaft 2 rotates to drive the incomplete gear 12 to rotate, the toothed part of the incomplete gear 12 is respectively meshed with the long gears 13 on the corresponding sides, at the moment, the incomplete gear 12 drives the two long gears 13 to rotate simultaneously, the rotation of the long gears 13 drives the coaxial winding wheel 14 to rotate, the rotation of the winding wheel 14 realizes the tightening of the rope 15, the tightening of the rope 15 realizes the approach of the upper end of the side plate 11 to the winding wheel 14, in the process, the first pressure spring 23 is compressed and enables the side plate to have a rebound trend and elastic potential energy, when the non-toothed part corresponds to the long gears 13 when the incomplete gear 12 moves, the outward turning of the side plate 11 is realized under the resetting action of the first pressure spring 23, and therefore the flapping action of the side plate 11 to the side wall of the ditch is.

The movement sequence of the device is that the shaft diameter of a connecting rod of a crankshaft 7 drives a piston rod 6 to move downwards through a first connecting rod 8, so that a pressing plate 3 moves downwards, after the pressing plate moves for a certain distance, a cam 9 is used for extruding an upright post 26 and a baffle 27 is driven through the upright post 26 to press a reversed V-shaped structure, so that a second connecting rod 10 is used for extruding the pressing plate 3 to move towards two sides, when the pressing plate 3 moves to the lowest end position, the pressing plate 3 moves to the outermost side position, at the moment, the meshed long gear 13 moves to correspond to the non-toothed part of an incomplete gear 12, at the moment, a pressed first pressure spring 23 is loosened, the side wall of a ditch is flapped, so that the whole ditch is vibrated and compacted, and at the middle position of the bottom of the ditch is leveled by moving a grinding roller.

The device has the following advantages compared with the leveling and compacting device:

1. according to the device, the crankshaft 7 rotates to drive the piston rod 6 to extrude the pressing plate 3 through the shaft diameter of the connecting rod to achieve downward movement of the pressing plate 3, at the moment, the pressing plate 3 gradually touches the bottom of a ditch and compresses the bottom of the ditch, meanwhile, the pressing plate 3 which moves downward gradually moves towards two sides under the action of the cam 9 extruding the inverted V-shaped structure through the upright post 26 and moves towards the outer side while compressing, the movement has the functions of compressing and leveling, the middle position of the ditch is slightly higher, two sides of the ditch are slightly lower, and leveling and compacting of the bottom of the ditch are achieved through repeated rolling of the grinding roller 16.

2. The device realizes that the long gear 13 is driven by the incomplete gear 12 when moving downwards and outwards, and the rope 15 is tightened by driving the winding wheel 14 by the long gear 13, so that the side plates 11 extrude the first compression spring 23 to realize the force storage of the side plates 11, and when the gear toothless part is not completely corresponding to the long gear 13, under the condition of being separated from the constraint of the incomplete gear 12, the side plates 11 at two sides can slap the side walls of the ditch under the self-resetting of the first compression spring 23, thereby realizing the leveling and compaction of the side walls.

3. This device clamp plate 3 and the 11 articulated position of curb plate that this device clamp plate 3 and the outside motion of the simultaneous cooperation of the up-and-down motion of clamp plate 3 realized to the side motion can contact and extrude the position of combining of irrigation canals and ditches bottom and side, and the motion trail of clamp plate 3 and the 11 articulated position of curb plate is the slope downwards, and this position is the difficult arrangement position of irrigation canals and ditches leveling device, and this device extrudees in the lump in the motion process to realize that this device function is more comprehensive.
