Abstract
A shock absorbing device prevents the suspended agricultural machinery from damaging by the vibrating force during operation, comprising a three-point suspending means (1) and a frame (6), between which a lower spring seat (7), an upper spring seat (10), a guide shaft (8), a guide shaft bush (9) and a spring (4) are positioned. The device can absorb and reduce the vibrating force generated by the machinery during operation through compression of the spring (4) and telescoping of the guide shaft (8) , thus avoiding breakage of the machinery due to vibration.
Description
Affiliated technical field
The utility model relates to a kind of device that can play damping and protective effect when the attached farm implement operation.
Background technology
At present, known suspension operation farm machinery are when carrying out operation, because the complexity of soil condition, to produce vibrations inevitably, this vibrations are harmful to farm machinery, often cause the damage of farm machinery parts and the craze and transfiguration of frame, have increased the maintenance capacity of farm machinery, reduced the service life of farm machinery, made the farm machinery can't normal operation when serious.
Summary of the invention
To hanging the destruction of farm machinery, the utility model provides a kind of shock-absorbing protecting device for fear of vibrations, after adding this device on the farm machinery that hang operation, can eliminate the destruction of vibrations to farm machinery substantially.
The technical scheme that the utility model technical solution problem is adopted is: increase spring vibration damper between trifilar suspension and frame, trifilar suspension is not directly to connect frame, but be connected simultaneously with frame with the damping spring seat by flexibly connecting pin, when frame produces vibrations, shaking force does not directly act on frame and hanger bracket, but by the compression of damping spring and guide shaft and flexible absorption of guide shaft cover stroke, thereby eliminated the impact of vibrations to farm machinery.
The beneficial effects of the utility model are: reduce the maintenance capacity of farm machinery, prolonged the service life of farm machinery.
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is a front view of the present utility model
Fig. 2 is a vertical view of the present utility model
Among the figure, 1, three-point hitch; 2, connecting pin; 3, connecting pin; 4, spring; 5, connecting pin; 6, frame; 7, lower spring cup; 8, guide shaft; 9, guide shaft cover; 10, upper spring seat;
Embodiment:
Three-point hitch (1) is connected by connecting pin (3) with frame (6), frame (6) is landed or fixedly the time, three-point hitch (1) can be that round spot is done garden arc motion up and down with connecting pin (3), when three-point hitch (1) fixedly the time, frame (6) can be that round spot is done garden arc motion up and down with connecting pin (3).Upper spring seat (10) is connected with three-point hitch (1) by connecting pin (2), on the lower spring cup (7), is connected with frame (6) by connecting pin (5).Guide shaft (8) is fixed on the lower spring cup (7), guide shaft cover (9) is fixed on that upper spring seat (10) upper leading axle (8) inserts in the guide shaft cover (9) but is not to insert fully, in guide shaft cover (10), in leave the space and can make guide shaft (8) in guide shaft cover (9), do stretching motion.Between upper spring seat (10) and the lower spring cup (7) spring (4) is arranged, can select the spring (4) of the different number of turns and intensity as required.When three-point hitch (1) is connected with dynamic power machine simultaneously that frame (6) places ground and when remaining static, spring (4) is in mild compression state while guide shaft (8) part and inserts in the guide shaft cover (9), farm machinery are under the operation travel condition, it is that round dot is done garden arc motion up and down and shaking force is conducted to guide shaft (8) and spring (4) by connecting pin (5) and lower spring cup (7) with connecting pin (3) that the shaking force that frame (6) produces makes frame (6), compression spring (4) also inserts in the guide shaft cover (9) guide shaft (8) more, after shaking force was eliminated, spring (4) and guide shaft (8) returned to static connection status.
Claims (4)
1, a kind of suspension farm machinery damping device that is used to hang on the operation farm machinery, between three-point hitch (1) and frame (6), lower spring cup (7) is housed, guide shaft (8), guide shaft cover (9), upper spring seat (10) and spring (4), frame (6) is connected with lower spring cup (7) by connecting pin (5) when being connected with three-point hitch (1) by connecting pin (3), three-point hitch (1) is connected with upper spring seat (10) by connecting pin (2) when being connected with frame (6) by connecting pin (3), it is that arc motion in garden was compressed spring (4) simultaneously to eliminate shaking force about round spot was done with connecting pin (3) that the vibrations that frame (6) produces when farm machinery are worked can make frame (6), makes farm machinery not be subjected to the destruction of shaking force.
2, suspension farm machinery damping device according to claim 1 is characterized in that: guide shaft (8), guide shaft cover (9) and spring (4) are arranged between lower spring cup (7) and the upper spring seat (10).
3, suspension farm machinery damping device according to claim 1 is characterized in that: guide shaft (8) inserts in the guide shaft cover (9) and can do stretching motion.
4, suspension farm machinery damping device according to claim 1, it is characterized in that: frame (6) is connected by connecting pin (3) with three-point hitch (1), and making frame (6) and three-point hitch (1) can be that round dot is done circular motion with connecting pin (3) all.
