Abstract
The utility model relates to a cushion damping mechanism for a land scraper work device, which is composed of a spherical hinge holder, a fixing big nut, a ball head pin, a butterfly-shaped spring group, etc., wherein the spherical hinge holder, the fixing big nut, the butterfly-shaped spring group, a frame ring, a slotting nut and a split pin are orderly installed on the ball head pin. The spherical hinge holder is linked and fixed on a front frame via a double-head stud. The fixing big nut is connected to a traction frame via the external thread of the fixing big nut. Wallop acting on a perching knife is transferred to the traction frame to compress a butterfly-shaped spring via the fixing big nut, and the wallop is transferred on a ball head of the ball head pin and the front frame after cushioned by the butterfly-shaped spring group, so that the impact from the ground on the frame, the shaft neck of the ball head pin, etc. is reduced. Meanwhile, when the butterfly-shaped spring group is compressed and deformed, the friction between springs is generated by relative slide, which can attenuate fleetly vibration. The cushion damping mechanism of a land scraper work device is simple in structure, and has functions of easing up impact and attenuating vibration in work.
Description
Technical field the utility model relates to the buffer damping mechanism that a kind of land leveller equipment is used.
Background technology
Equipment is one of critical component of land leveller, and its effect is to finish the most basic level land function of land leveller.The equipment of present homemade land leveller all is to adopt to be rigidly connected to the structural member between the forebay, because ground effects had certain impact sometimes in the power of perching knife when land leveller carried out level land work, and the stress of the impact stress that produces when impacting during much larger than smooth working, the member that causes land leveller is because of the destruction often that is hit.
The summary of the invention the purpose of this utility model provides the buffer damping mechanism that a kind of land leveller equipment is used.
The purpose of this utility model is achieved in that this buffer damping mechanism is by ball stud, ball pivot seat, fixedly big nut, butterfly spring group, Supporting ring, slotted nut, cottor pin etc. are formed, ball pivot seat, fixedly big nut, butterfly spring group, Supporting ring, slotted nut, cottor pin are housed on the ball stud successively, the ball pivot seat is fixed on the forebay by studs, and fixedly big nut is connected on the hitch frame by its external screw thread.The impact force that acts on perching knife is delivered to behind the hitch frame by fixing big nut compresses the butterfly spring group, could finally be delivered on ball stud bulb and the forebay after the buffering through the butterfly spring group, so just relaxed from the impact on the ground influence to positions such as frame and ball stud axle journals, sliding between each sheet during butterfly spring group compressive strain simultaneously produces frictional force and can impel vibrations decay fast.The utility model is simple in structure, and it can reach the purpose that shock attenuation is impacted and impelled in effective mitigation by using the butterfly spring group.
Described ball stud one side is a bulb, opposite side band external screw thread, and the middle part is a multidiameter.
Described fixedly big nut hollow, a side band external screw thread.
The section of described butterfly spring group medi-spring is the butterfly section.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structure chart of present embodiment.
1. forebaies among the figure, 2. ball stud, 3. ball pivot seat, 4. lubricating cup, 5. studs, 6. nut, 7. thin nut, 8. fixing big nut, 9. holding screw, 10. butterfly spring group, 11. hitch frames, 12. Supporting rings, 13. slotted nuts, 14. cottor pins.
The specific embodiment
Ball pivot seat (3), fixedly big nut (8), butterfly spring group (10), Supporting ring (12), slotted nut (13) are enclosed within on the ball stud (2) successively, ball pivot seat (3) is fixed on the forebay (1) by studs (5), nut (6), thin nut (7), fixedly big nut (8) and hitch frame (11) spiral marking connection, lubricating cup (4) is installed in fixedly on the big nut (8) and ball pivot seat (3), holding screw (9) positioning towed (11) and fixing big nut (8).By above installation, finish present embodiment.
Claims (4)
1. buffer damping mechanism, ball pivot seat, fixedly big nut, butterfly spring group, Supporting ring, slotted nut, cottor pin are housed on the ball stud successively, the ball pivot seat is fixed on the forebay by studs, fixedly big nut is connected on the hitch frame by its external screw thread, it is characterized in that: the impact force that acts on perching knife is delivered to behind the hitch frame by fixing big nut compression butterfly spring, could finally be delivered on ball stud bulb and the forebay after passing through the buffering of butterfly spring group.
