Abstract
The utility model discloses a cutting knife drive damping device for a harvester, which comprises a movable knife bar, a cutting knife drive bar, a connecting block, a swing arm, a damping ring and blocking plates, wherein one end of the cutting knife drive bar is fixedly connected with the movable knife bar, the blocking plates are symmetrically arranged on two sides of the damping ring, one end of the connecting block is fixedly connected with the other end of the cutting knife drive bar, the other end of the connecting block is arranged in a notch at the lower end of the swing arm and is in hinged connection with the lower end of the swing arm through a connecting bolt, a bearing is sleeved on the connecting bolt, two sides of the bearing are axially positioned through spacer bushes respectively, the damping ring is sleeved on the bearing, and two sides of the damping ring are axially positioned in inner holes at the other end of the connecting block through the blocking plates and a blocking ring respectively. According to the cutting knife drive damping device for the harvester, the damping ring is additionally arranged between the inner holes of the connecting block and the bearing, so that the impact and shock of the movable knife bar to the cutting knife drive damping device are remarkably reduced, a normal work of the cutting knife drive damping device can be guaranteed, the reliability is high, and the service life is long.
Description
Technical field
The utility model relates to a kind of grain header cutter drive unit, and especially a kind of damping of grain header cutter drive unit belongs to agricultural machinery technological field.
Background technology
Grain header is in harvesting during operation, and the cutter drive unit moves back and forth about through linkage, drives swing arm and press the certain angle reciprocally swinging, moves back and forth and gathers in cereal thereby drive knife section through the moving knife bar.Because when the moving knife bar moves back and forth, inertia force produces greater impact and vibrations to the cutter drive unit during high-frequency direction transformation, has influenced the operate as normal of cutter drive unit, has reduced its service life, and the reliability of cutter drive unit is relatively poor.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, reliability is higher and the grain header cutter that can reduce moving knife pole pair cutter drive unit impulsive force drives damping device.
The utility model is achieved through following technical scheme:
A kind of grain header cutter drives damping device; Comprise cutter driving rod, contiguous block, swing arm that moving knife bar, an end are fixedly connected with the moving knife bar; Contiguous block one end is fixedly connected with the cutter driving rod other end; The contiguous block other end is arranged in the notch of swing arm lower end, and is hinged through connecting bolt and swing arm lower end.Bearing holder (housing, cover) is contained on the connecting bolt, and said bearing both sides are respectively through the spacer axial location.Also comprise shock absorbing ring, be symmetricly set on the baffle plate of shock absorbing ring both sides, said shock absorbing ring is sleeved on the bearing, the shock absorbing ring both sides respectively through baffle plate, back-up ring axial location in contiguous block other end endoporus.
The purpose of the utility model can also further realize through following technical measures.
Aforesaid grain header cutter drives damping device, and wherein said bearing is a needle bearing.
Aforesaid grain header cutter drives damping device, is provided with radial clearance S between wherein said spacer and the baffle plate, and radial clearance S is 3mm～4mm.
Aforesaid grain header cutter drives damping device, and the material of wherein said shock absorbing ring is the yielding rubber of hardness greater than Shao Shi 80 degree.
The utility model is set up shock absorbing ring between contiguous block endoporus and bearing; Making cutter drive unit and being connected of moving knife bar change elasticity into by being rigidly connected connects; Greatly reduce the impact and the vibrations of moving knife pole pair cutter drive unit; Guaranteed the operate as normal of cutter drive unit, reliability is high, long service life.
Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2; The utility model comprises cutter driving rod 2, contiguous block 3, swing arm 4, shock absorbing ring 5, the baffle plate 6 that is symmetricly set on shock absorbing ring 5 both sides, the back-up ring 7 that moving knife bar 1, left end are fixedly connected with moving knife bar 1 through a plurality of rivets; Contiguous block 3 left ends are fixedly connected with cutter driving rod 2 right-hand members through securing member; Contiguous block 3 right-hand members are arranged in the swing arm 4 lower end notches, are sleeved on the connecting bolt 8, and are hinged through connecting bolt 8 and swing arm 4 lower ends; Shock absorbing ring 5 is sleeved on the needle bearing 9, and needle bearing 9 both sides are respectively through spacer 10 axial location.Baffle plate 6 is symmetricly set on shock absorbing ring 5 both sides, and shock absorbing ring 5 is embedded between contiguous block 3 other end endoporus and needle bearing 9 cylindricals, and its both sides are passed through baffle plate 6, back-up ring 7 axial location respectively in contiguous block 3 endoporus.Be provided with radial clearance S between spacer 10 and the baffle plate 6, radial clearance S is 3mm～4mm, and S is 3.5mm in the present embodiment, and the material of shock absorbing ring 5 is the yielding rubber of hardness greater than Shao Shi 80 degree.Be provided with 3mm～4mm radial clearance S between spacer 10 and the baffle plate 6; The S of present embodiment is 3.5mm; Radial clearance S is used for shock absorbing ring 5 when receiving blastic deformation, and the effect of protection connecting bolt 8 is played with respect to the left and right sides offset in contiguous block 3 endoporus axle center in connecting bolt 8 axle center.
Except that the foregoing description, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
