Abstract
The utility model provides a perching knife chute gap adjusting mechanism, which comprises a traverse table, a guide groove, a baffle, a right-angled copper bush, a set screw, a thin nut, a bolt, an angular position device and the like. The guide groove and the traverse table are installed on the angular position device through the bolt, the lower end of the set screw on the vertical direction of the guide groove is pressed against the baffle, wherein the baffle tightly compresses the right-angled copper bush, the set screw at the rear side of the guide slot is pressed against the side of the angular position device horizontal block, and the set screw is locked by the thin nut after tightened. The perching knife chute gap adjusting mechanism has a simple structure, when the relative movement of the right-angled copper bush and the perching knife guide rail causes wear to produce large gap, the locked thin nut and the fixed bolt are loosened, the underside (or the superface) set screw is twisted, and the baffle presses the right-angled copper bush in order to adjoin the bottom (or the superface) of the perching knife guide rail; the rear set screw is twisted, and the guide slot and the outboard right-angled copper bush move to the back side together to allow the right-angled copper bush to adjoin the side surface of the perching knife guide rail. The gap of the right-angled copper bush and the perching knife guide rail in the guide slot can be eliminated by the adjustment in order to allow the perching knife to keep steady when working.
Description
Technical field the utility model relates to the perching knife chute clearance adjustment mechanism that a kind of land leveller is used.
Background technology
Perching knife often will be done the flexible adjustment of side direction as the main equipment of land leveller when carrying out smooth operation.In order to realize this function, the land leveller perching knife is generally all made the structure of band chute.The influence of perching knife vibrations when rubbing for a long time and working, the gap between chute and the guide rail is strengthened gradually, can cause perching knife work not steady.Just anti-wearing liner slows down wearing and tearing to land leveller or increase pad quantity is offset the gap through increasing at present, lacks effective guiding mechanism for the gap between perching knife chute and the guide rail.
Summary of the invention can not effectively be adjusted the deficiency in gap between perching knife chute and the guide rail in order to overcome existing land leveller, and the utility model provides a kind of perching knife chute clearance adjustment mechanism.
The purpose of the utility model is achieved in that this perching knife chute clearance adjustment mechanism is made up of tablet, guide groove, dividing plate, right angle copper bush, holding screw, thin nut, bolt and position, angle device etc.Wherein, the upper and lower side of position, angle device respectively is welded with a horizontal piece, and the rear side of guide groove has notch; Translation before and after can be on the device of position, angle, tablet and guide groove are installed to two ends about the device of position, angle through set bolt, and the holding screw lower end on the guide groove vertical direction withstands on the dividing plate; Dividing plate compresses the right angle copper bush; The right angle copper bush directly contacts with the perching knife guide rail, and the holding screw of guide groove rear side withstands on the side of the horizontal piece of position, angle device, all pins with thin nut after holding screw is tightened.When between right angle copper bush and the perching knife guide rail because relative motion when causing wearing and tearing to produce big gap; Unclamp the thin nut and the set bolt of locking; Be screwed into the holding screw of guide groove vertical direction, dividing plate will compress the right angle copper bush, make it the end face of perching knife guide rail; Be screwed into the holding screw of guide groove rear side, the lateral movement backward together of the right angle copper bush in the guide groove and the outside makes the right angle copper bush press close to the side of perching knife guide rail; After regulating completion, fastening again thin nut and set bolt.Through with adjusted, can eliminate the gap between interior right angle copper bush of guide groove and the perching knife guide rail.
Its installing hole of said guide groove is a slotted hole, and rear side has notch, can front and back translation on the device of position, angle.
Position, said angle device upper and lower side respectively is welded with a horizontal piece, forms T type structure.
The beneficial effect of the utility model is: can adjust the gap between perching knife chute and the guide rail respectively in the vertical direction and the side of perching knife guide rail, make perching knife held stationary when work, improve the smooth precision of land leveller.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structure chart of present embodiment.
Fig. 2 is the vertical view of guide groove among Fig. 1 (3).
Fig. 3 is the vertical view of position, angle device (8) among Fig. 1.
1. right angle copper bush among the figure, 2. dividing plate, 3. guide groove, 4. holding screw, 5. thin nut, 6. set bolt, 7. tablet, 8. position, angle device, 9. perching knife guide rail.
The specific embodiment
Guide groove (3) and tablet (7) are installed on position, the angle device (8) through set bolt (6); Holding screw (4) lower end on guide groove (3) vertical direction withstands on the dividing plate (2); Dividing plate (2) compresses right angle copper bush (1); The holding screw (4) of guide groove (3) rear side withstands on the horizontal piece side of position, angle device (8), and holding screw (4) is tightened the back and pinned with thin nut (5).Through above installation, accomplish present embodiment.
Claims (4)
1. perching knife chute clearance adjustment mechanism; Be made up of tablet, guide groove, dividing plate, right angle copper bush, holding screw, thin nut, bolt and position, angle device etc., it is characterized in that: tablet and guide groove are installed to position, angle device two ends up and down through set bolt, and the holding screw lower end on the guide groove vertical direction withstands on the dividing plate; Dividing plate compresses the right angle copper bush; The right angle copper bush directly contacts with the perching knife guide rail, and the holding screw of guide groove rear side withstands on the side of the horizontal piece of position, angle device, all pins with thin nut after holding screw is tightened; Be screwed into holding screw, can eliminate the gap between interior right angle copper bush of guide groove and the perching knife guide rail.
