Specific work process of the invention: when in use, the present apparatus is placed in has dug irrigation canals and ditches bottom to be flattened to the present apparatus
Portion, so that two are driven away roller 17 and flowed to along irrigation canals and ditches and arranged and two 10 bottoms of side plate making are in irrigation canals and ditches two sides, use process
Driving device is described by taking motor driven as an example, opens driving motor at this time, so that motor is rotated through deceleration shaft 2, at this time
Rotation will drive the rotation of cam 7, disk 8 and turntable 11 fixed thereon.
When shaft 2 is rotated with moving cam 7, the cam 7 when the rise of cam 7 is contacted with corresponding 3 end face of side plate
Two pressing plates 3 can be headed on to two sides backwards to movement, tension spring 18 can be made to be stretched when two pressing plates 3 are mobile backwards at this time, and make
It has the trend and elastic potential energy resetted, can be real under the reset response of tension spring 18 when the backhaul of cam 7 is contacted with pressing plate 3
For existing two pressing plates 3 to intermediate reset, whens two 3 side-to-side movements of pressing plate, can realize that column 6 follows its side-to-side movement, be covered at this time vertical
Through slot 19 of the meeting of sliding block 5 in transverse slat 4 on column 6 horizontally slips to realize the side-to-side movement of the present apparatus along sliding slot 20.
When shaft 2 drives disk 8 to rotate, two on 8 lower end surface of disk are about the symmetrical arc of 8 axis centre of disk
Protrusion block 9 rotates, and both ends and the disk 8 of arc-shaped protrusions block 9 are to be smoothly connected, when disk 8 turns to and 6 upper-end contact of column
When, moving downward for column 6 can be realized under the extruding of arc-shaped protrusions block 9, column 6 moves downward at this time, and column 6 moves downward
It can realize that column 6 is moved downward with 3 entirety of dynamic pressure plate, the second pressure spring 24 being cased on column 6 at this time is compressed, and is made it have
The trend and elastic potential energy of rebound, this process are to realize the up and down motion of pressing plate 3.
When shaft 2 rotates, and turntable 11 is driven to rotate, the sleeve 14 that the rotation of turntable 11 will drive in its T-slot 12 is followed
It is moved, and rope 16 is tightened at this time, as the ball 26 that rope 16 tightens 15 upper and lower ends of wedge block contacts the slot of T-slot 12
Wall is simultaneously rolled along the cell wall of T-slot 12, so that turntable 11 rotates, sleeve 14 is motionless, is transported as turntable 11 turns to sleeve 14
When moving to 13 position of deep gouge, two sliding blocks 5 in sleeve 14 pop up under the reset response of third pressure spring 25 and squeeze deep gouge 13
Cell wall, wedge block 15 stretches out at this time, and with the rotation of turntable 11, sleeve 14 drives wedge block 15 gradually to slide into deep gouge 13 and T
On the cell wall of 12 junction of shape slot, it is extruded with inwardly with two wedge blocks 15 of the rotation of turntable 11 by 13 cell wall of deep gouge at this time
The trend of movement, sleeve 14 starts that turntable 11 is followed to move again at this time, and rope 16 is tightened, and side plate 10 is pulled up, side plate 10
The first pressure spring 22 is squeezed when pull-up and make the first pressure spring 22 have rebound trend and elastic potential energy, with the first pressure spring 22 by
Pulling force increases, and third pressure spring 25 is squeezed power and is gradually increased, the extruding force that two wedge blocks 15 are subject at this time make enough its to
Contract, the and when width after the contraction allow is moved in T-slot 12, sleeve 14 enters T-slot 12, at this time ball 26 with
The cell wall contact of T-slot 12 is rolling friction, and barrier force moment reduces, and the first pressure spring 22, which resets, realizes stirring outward for plate,
To realize the movement that side plate 10 is patted to trench sidewall.
The present apparatus can be each to realize by adjusting cam 7, the relative positional relationship of disk 8 and turntable 11 in shaft 2
Position movement successively in proper order, present apparatus optimal motion sequence is first to realize that arc-shaped protrusions block 9 squeezes column 6, to realize pressure
Plate 3 moves downward, after moving a distance realize cam 7 push pressing plate 3 moved to two sides, when pressing plate 3 move to it is most lower
It realizes that pressing plate 3 moves to outermost locations simultaneously when end position, has stretched rope 16 with moving sleeve 14 by deep gouge 13 at this time
It reaches stress critical value and realizes that sleeve 14 leaves deep gouge 13, the first pressure spring 22 being compacted at this time is released, and is realized to irrigation canals and ditches
The slap of side wall, to realize that the vibration to irrigation canals and ditches entirety is compacted, trench bottom middle position passes through back-and-forth motion at the same time
The realization of roller 17 is driven away to flatten it.
Present apparatus comparison leveling compaction apparatus has following benefit:
1, the present apparatus first passes through arc-shaped protrusions block 9 there are following movement and squeezes column 6 to realizing moving down for pressing plate 3, this
When during pressing plate 3 gradually touch trench bottom and realize to trench bottom compress at the same time under the extruding of cam 7
The pressing plate 3 moved downward is gradually moved to two sides, is realized while compressing and is moved outward, this movement, which not only has, to be compressed
There is also floating functions for journey, while can realize that the slightly higher two sides in the middle position of irrigation canals and ditches are slightly lower, by driving rolling repeatedly for roller 17 away
To realize that the leveling to trench bottom is compacted.
2, the present apparatus is realized while moving downward and moving out hauls 16 through sleeve 14 through turntable 11, from
And realize that side plate 10 squeezes the storage power that the first pressure spring 22 realizes side plate 10, after wedge block 15 is detached from out of deep gouge 13, first
Under 22 reset itself of pressure spring, realizes that two sides side plate 10 flops trench sidewall, realize the leveling and compacting of side wall.
3, the present apparatus moves up and down in pressing plate 3 while the present apparatus pressing plate 3 for moving realization outward and side plate 10 being cooperated to cut with scissors
Connecing position can contact and squeeze the binding site of trench bottom and side, and the motion profile of 10 articulated position of pressing plate 3 and side plate is
Diagonally downward, this position is the more difficult justification of irrigation canals and ditches apparatus for leveling, and the present apparatus squeezes together during the motion, to realize
Present apparatus function is more comprehensive.
Present inventive concept is novel, and clever structure is practical, realizes side-to-side movement simultaneously by the up and down motion of pressing plate,
And cooperate side plate to the slap of trench sidewall to realize that irrigation canals and ditches leveling compacting is more efficient and rational.
