Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
A kind of ground apparatus for leveling, as depicted in figs. 1 and 2, including rack 1 and the hydraulic telescopic rod being connected in rack 1
2,2 end of hydraulic telescopic rod is fixedly connected with horizontally disposed connection frame 3, and the both ends of connection frame 3 have been respectively fixedly connected with hydraulic
The piston rod of cylinder 4, hydraulic cylinder 4 is vertically arranged and piston-rod end is fixed with horizontally disposed auger frame 5, and auger frame 5 is equipped with
Hydraulic motor 6, hydraulic motor 6 are sequentially connected with the auger 7 along the setting of 5 length direction of auger frame, are fixed on front side of auger frame 5 whole
Plate 9 is provided with the cleaning mechanism 8 cleared up 9 bottom surface of screed on screed 9.When being flattened to concrete, leveling
Device is mobile using retrusive, and behind the position that auger frame 5 and screed 9 are adjusted by hydraulic cylinder 4, hydraulic motor 6 drives auger 7
After concrete is tentatively shakeout, pass through 9 screeding concrete of screed.
Cleaning mechanism 8 includes the support frame 81 for sliding vertically connection and screed 9, along 9 width direction of screed sliding company
Support frame 81 is connected to slide vertically with scraper plate 82, the driving support frame 81 for clearing up 9 bottom surface of screed relative to screed 9
Drive scraper plate 82 along 9 width direction of screed when second driving mechanism 84 and 82 upper surface of scraper plate are flushed with 9 bottom surface of screed
First driving mechanism 83 of sliding；Scraper plate 82 is arranged along 9 length direction of screed and 82 length of scraper plate is greater than 9 length of screed,
82 bottom surface of scraper plate is higher than screed bottom surface when 9 bottom surface of screed is bonded with concrete surface, prevents support frame 81 and scraper plate 82 from interfering
The normal work of screed 9.
Second driving mechanism 84 includes the first driving section being fixed on connection frame 3, is provided with leveling on screed 9
Moved on to after being detached from concrete surface on plate 9 cooperates driving support frame 81 with respect to the second transmission that screed 9 moves down with the first driving section
Portion.
Second driving section includes that the screw rod 841 being threaded through on support frame 81 vertically and first be fixed on screw rod 841 are bored
Gear 842, screw rod 841 are threadedly coupled with support frame 81, and screw rod 841 is rotationally connected with screed 9；First driving section includes fixing
On connection frame 3 and the first rack gear 843 for being vertically arranged, supporting element 844, the company of rotation on supporting element 844 are fixed on screed 9
It is connected to horizontally disposed shaft 845, the second bevel gear 846 engaged with first bevel gear 842, shaft are fixed in shaft 845
The first gear 847 for moving on on screed 9 and being detached from and engaging after concrete surface with the first rack gear 843 is fixed on 845.Leveling is completed
Afterwards, first gear 847 after being detached from concrete surface is moved on on the driving of hydraulic cylinder 4 screed 9 to engage with the first rack gear 843, the first tooth
843 position of item is constant, and screed 9 continues first gear 847 during moving up and rotates, and drives screw rod by double bear gear transmission
841 rotations, so that support frame 81 and scraper plate 82 be driven to move down with respect to screed 9, support frame 81 move down into 82 upper surface of scraper plate with
When screed 9 flushes, scraper plate 82 slides the concrete of adhesion on cleaning 9 bottom surface of screed along 9 width direction of screed, prevents from mixing
It is inconvenient to clear up after solidifying soil solidification.
The first gear 847 is engaged with the first rack gear 843 when moving on to predetermined altitude on screed 9, predetermined altitude be from
20~60cm of ground.It avoids carrying out screed 9 support frame 81 and scraper plate 82 when height adjusts by a small margin to move down with respect to screed 9,
Prevent scraper plate 82 and support frame 81 from causing to hinder to the normal work of screed 9.
Support frame 81 and scraper plate 82 are located at 9 front side of screed, and the first driving mechanism 83 includes the cunning being fixed on scraper plate 82

832, the front side of the second rack gear 832 is the flank of tooth；The second gear engaged with sliding rack 831 is rotatably connected on support frame 81
833, the third gear 834 engaged with second gear 833 is rotatably connected on support frame 81, is moved on in first gear 847 and the
82 upper surface of scraper plate is flushed with 9 lower end surface of screed when one rack gear 843 separates, and is moved on in first gear 847 and the first rack gear 843
Third gear 834 is engaged with the second rack gear 832 when separation.It moves on in first gear 847 and moves on to and the first rack gear on screed 9
After 843 separation, the position of support frame 81 is remained unchanged, and third gear 834 is engaged with the second rack gear 832 at this time, and screed 9 continues
Third gear 834 rotates during moving up, to drive second gear 833 to rotate, to drive sliding rack 831 and scraper plate
82, to the concrete for striking off 9 bottom surface of screed close to the sliding of 9 direction of screed, clear up without artificial, convenient and efficient, while will be whole
Plate 9 moves up the sliding for being converted into scraper plate 82, without increasing additional power source for scraper plate 82, reduces production cost.
Scraper plate 82 is equipped with close to the side of screed 9 to the inclined-plane 10 tilted upward close to 9 direction of screed.Convenient for scraper plate
82 remove the stronger concrete of adhesive.
Scraper plate 82 is located at 81 lower part of support frame.Reduce support frame 81 with respect to screed 9 move down into 82 upper surface of scraper plate with it is whole
The displacement stroke that 9 bottom surface of plate flushes reduces the load and energy consumption of hydraulic cylinder 4.
82 both ends of scraper plate are fixedly installed the auxiliary formation plate 11 outside 9 travel path of screed, and the leveling of screed 9 is mixed
Auxiliary 11 bottom surface of formation plate is flushed with 9 bottom surface of screed when solidifying soil.When apparatus for leveling falls back formula walking, by assisting screed 11
82 both ends of finishing smoother concrete outstanding.
Specific work process: as shown in Figures 1 to 4, by screed 9 to concrete carry out it is smooth after, hydraulic cylinder 4 drive
It moves on to first gear 847 after being detached from concrete surface on screed 9 to engage with the first rack gear 843, screed 9 continues the process moved up
Middle first gear 847 rotates, and drives screw rod 841 to rotate by double bear gear transmission, to drive 82 phase of support frame 81 and scraper plate
Screed 9 is moved down, is moved on on screed 9 in first gear 847 after moving on to and being separated with the first rack gear 843, the position of support frame 81
It sets and remains unchanged, third gear 834 is engaged with the second rack gear 832 at this time, and screed 9 continues third gear during moving up
834 rotations, to drive second gear 833 to rotate, to drive sliding rack 831 and scraper plate 82 to close to 9 direction of screed
The concrete of 9 bottom surface of screed is struck off in sliding, clears up inconvenience after preventing concrete setting, convenient and efficient without artificial cleaning.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present invention after reading this specification, but as long as in this hair
All by the protection of Patent Law in bright scope of the claims.
