Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are clearly and completely described below, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, are also within the scope of the present application based on the embodiments herein. In addition, the embodiments and features in the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a vibration damping device for an agricultural engine according to an embodiment of the present application. As shown in fig. 1, 2 and 3, the damping device for the agricultural engine comprises an engine 1, a bracket 2, a damping mechanism and a jacket 5;
the two opposite edges of the lower surface of the engine 1 are fixedly provided with the brackets 2 respectively, and the lower end of each bracket 2 is fixedly connected with the damping mechanism;
the damping mechanism includes: base 301, hydraulic cylinder 302, piston 303, first connecting rod 304, first spring 306, first mount 305;
the hydraulic cylinder 302 is fixed on the upper surface of the base 301;
the piston 303 is arranged in the inner cavity of the hydraulic cylinder 302, and the piston 303 can move up and down in the hydraulic cylinder 302;
an opening is formed in the upper surface of the hydraulic cylinder 302, one end of the first connecting rod 304 passes through the opening and is fixed on the upper surface of the piston 303, and the other end is fixed on the lower surface of the first mounting seat 305; the first spring 306 is sleeved on the first connecting rod 304, the upper end of the first spring 306 is fixedly connected with the lower surface of the first mounting seat 305, and the lower end is fixedly connected with the upper surface of the hydraulic cylinder 302;
the first mounting seat 305 is fixedly connected with the lower end of the bracket 2;
the outside of pneumatic cylinder 302 sets up and presss from both sides cover 5, press from both sides cover 5 with the cavity is formed between the pneumatic cylinder 302 surface, press from both sides the lower extreme of cover 5 with the lower surface parallel and level of pneumatic cylinder 302, the upper end is higher than the pneumatic cylinder 302 upper surface.
It should be noted that, the number of the damping mechanisms at the lower end of the support 2 is related to the shape and structure of the support 2, for example, as shown in fig. 1, 2 and 3, a damping mechanism may be disposed at two lower corners of the trapezoid, and two damping mechanisms are one group.
Because the external vibration is uncertain, the piston 303 can move up and down, back and forth or left and right in the hydraulic cylinder 302, during the movement, hydraulic oil in the hydraulic cylinder 302 is extruded, and during the extrusion, the hydraulic oil is inevitably splashed out from an opening of the hydraulic cylinder 302, so that the environment is polluted, and the hydraulic oil is wasted. Therefore, the oil splashed out after the jacket 5 is arranged can be directly sprinkled into a cavity formed by the jacket 5, so that the splashed oil is recovered, and the waste of the oil is reduced.
In addition, the piston 303 moves in the hydraulic cylinder, and inevitably rubs against the side wall of the hydraulic cylinder 302, and after long-term friction, the wall of the hydraulic cylinder 302 is likely to be broken, so that the hydraulic cylinder 302 needs to be replaced immediately. After the jacket 5 is arranged, if the hydraulic cylinder 302 is damaged, hydraulic oil in the hydraulic cylinder can also infiltrate into the jacket 5, so that the oil is recovered, and the waste is reduced; further, since the hydraulic oil is recovered by the jacket 5, there is no need to consider the problem of waste of the hydraulic oil, and therefore, the damper mechanism can be used continuously without the replacement of the hydraulic cylinder 302, and the service life of the damper mechanism can be prolonged.
The upper end of the jacket 5 is higher than the upper surface of the hydraulic cylinder 302, so that more splashed oil can be received, and when the side wall of the hydraulic cylinder 302 is broken, the piston 303 presses the hydraulic oil downwards, and when the hydraulic oil is higher than the upper surface of the hydraulic cylinder 302, the hydraulic oil flows into the hydraulic cylinder 302 again through the opening to form circulation.
Here, after the side wall of the hydraulic cylinder 302 is damaged, the damping effect of the hydraulic cylinder 302 is necessarily affected, and of course, the damage is small, the damage is also small, the damage is large, and the impact is also large, but the damping mechanism can still damp the shock through the first spring 306.
The working principle of the damping device of the agricultural engine is as follows:
when the agricultural machine works, the engine 1 can vibrate up and down, when the downward force is generated by vibration, the engine 1 body can transmit the force to the first mounting seat 305 through the bracket 2, and then the first mounting seat 305 can drive the first connecting rod 304 connected with the first mounting seat to move downwards, so that the first spring 306 can be compressed, and the downward force is buffered. Meanwhile, the first connecting rod 304 also drives the piston 303 to move downwards, hydraulic oil under the piston 303 generates an upward force on the piston 303, and further slows down the downward movement of the piston 303, so that the downward movement speed of the first connecting rod 304 is also slowed down, and the vibration amplitude is further relieved.
When the upward force is generated by vibration, the body of the engine 1 transmits the force to the first mounting seat 305 through the bracket 2, then the first mounting seat 305 drives the first connecting rod 304 connected with the first mounting seat to move upward, so that the piston 303 is driven to move upward, the hydraulic oil on the upper part of the piston 303 can generate downward force on the piston 303, the upward force and speed of the piston 303 are further weakened, and the upward movement speed of the first connecting rod 304 is further reduced, so that the vibration is reduced.
At the same time, the oil splashed from the hydraulic cylinder 302 by the damper mechanism is scattered into the jacket 5 during vibration, and recovered by the jacket 5.
Further, in the use process, when the side wall of the hydraulic cylinder 302 is worn out, hydraulic oil is added into the jacket 5, the liquid level of the hydraulic oil in the jacket 5 is the same as the liquid level of the hydraulic cylinder 302, when the side wall of the hydraulic cylinder 302 is worn out, the hydraulic cylinder 302 is communicated with the jacket 5, and because the hydraulic oil is also in the jacket 5, the liquid level of the hydraulic oil in the hydraulic cylinder 302 cannot be reduced, when the piston 303 presses the hydraulic oil downwards, a part of the hydraulic oil in the hydraulic cylinder 302 moves upwards, and a part of the hydraulic oil flows into the jacket 5 through the broken side wall, and if the liquid level in the jacket 5 is higher than the height of the hydraulic cylinder 302, the hydraulic oil flows into the hydraulic cylinder through an opening at the upper part of the hydraulic cylinder, so that a certain damping effect is still achieved, the service life of the hydraulic cylinder 302 is prolonged, and the service life of the damping mechanism is prolonged.
From the above, it can be seen that the vibration reduction device for the agricultural engine provided by the embodiment of the application is additionally provided with the vibration reduction mechanism, wherein the vibration reduction mechanism comprises spring vibration reduction and hydraulic cylinder vibration reduction, and the vibration reduction effect is obvious through superposition of the spring and the hydraulic cylinder, so that the vibration condition of the agricultural engine in the use process can be effectively reduced, the abrasion is reduced, and the service life of the agricultural engine is prolonged; further, jacket 5 is arranged outside hydraulic cylinder 302, so that splashed oil can be recovered through jacket 5, waste is reduced, hydraulic cylinder 302 can continue to work, service life of hydraulic cylinder 302 is prolonged, and service life of the damping mechanism is prolonged.
Of course, three or more shock absorbing mechanisms may be uniformly arranged at the lower surface of the bottom side of the ladder frame 2, which is not limited in the embodiment of the present application.
Alternatively, the structure of the bracket 2 is not limited to the trapezoid structure shown in the drawings, but may be a rectangular structure, which is not limited in this embodiment of the present application.
Alternatively, the engine 1 and the bracket 2 may be connected by welding, threads, or the like, which is not limited in the embodiment of the present application.
Alternatively, the jacket 5 is fixed on the outer side of the hydraulic cylinder 302 by welding, or the like, and of course, other manners may be used to fix the jacket on the outer side of the hydraulic cylinder 302, which is not limited in this application, as long as it is ensured that the jacket 5 does not leak oil after fixing.
Optionally, a second spring 6 is disposed on the lower surface of the piston 303, one end of the second spring 6 is fixedly connected with the lower surface of the piston 303, and the other end is fixedly connected with the bottom surface of the inner cavity of the hydraulic cylinder 302.
When the agricultural engine 1 vibrates up and down, the piston 303 is driven by the first connecting rod 304 to move up or down, and at this time, the second spring 6 is also stretched or extruded, so as to play a role in buffering, and further achieve a damping effect.
Optionally, a fourth spring (not shown in the figure) is sleeved on the lower end portion of the first connecting rod 304, the upper end of the fourth spring is fixedly connected with the inner top surface of the hydraulic cylinder 302, and the lower end of the fourth spring is fixedly connected with the upper surface of the piston 303.
When the agricultural engine 1 vibrates up and down, the piston 303 is driven by the first connecting rod 304 to move up or down, and at this time, the fourth spring is also extruded or stretched, so as to play a role in buffering, and further achieve a damping effect.
Optionally, referring to fig. 3, a plurality of through holes are provided on the piston 303.
If the tightness between the side wall of the piston 303 and the side wall of the hydraulic cylinder 302 is too good, so that the velocity of the hydraulic oil flowing up and down is very small, the piston 303 cannot move basically when receiving downward force, so that the damping effect is very small, and therefore, a plurality of through holes are formed in the piston 303, which can enable the hydraulic oil in the hydraulic cylinder 302 to flow up and down, play a certain role in blocking the piston 303, but cannot completely block the movement of the piston 303, and the velocity of the back and forth movement of the piston 303 is gentle, so that the velocity of the movement of the first connecting rod 304 is also gentle, and the vibration amplitude is weakened.
Of course, it is noted here that the through hole is generally small, and can be determined based on empirical values, so that it is possible to make the piston 303 run slowly.
Optionally, referring to fig. 3, the shock absorbing device further includes an auxiliary shock absorbing mechanism, the auxiliary shock absorbing mechanism including: a second mount 307, a cross bar 308, a third spring 310, a connecting ring 309, a second connecting rod 313, a third mount 311, a fourth mount 312;
two second mounting seats 307 are symmetrically and fixedly connected to the upper surface of the base 301, a cross rod 308 is fixedly mounted between the two second mounting seats 307, the surface of the cross rod 308 is sleeved with a third spring 310, two ends of the third spring 310 are respectively and fixedly connected with two connecting rings 309, and the side wall of each connecting ring 309 is fixedly connected with a third mounting seat 311;
the fourth mounting seats 312 are symmetrically and fixedly arranged on the lower surface of the bracket 2;
the two ends of the second connecting rod 313 are respectively mechanically connected with the third mounting seat 311 and the fourth mounting seat 312.
The working principle of the auxiliary damping mechanism is as follows:
when the agricultural machine works, the engine 1 can vibrate up and down, when the engine 1 vibrates, the engine 1 body can push the second connecting rod 313 through the bracket 2, the inclination angle of the second connecting rod 313 is changed, then the second connecting rod 313 pushes the connecting ring 309 to extrude or stretch the third spring 310, so that the third spring 310 is used for buffering vibration, and the damping effect is improved.
Optionally, referring to fig. 3, a plurality of dampers 4 are disposed between the base 301 and the support 2, the upper ends of the dampers 4 are fixedly connected to the lower surface of the support 2, and the lower ends of the dampers 4 are fixedly connected to the upper surface of the base 301.
The damper 4 may play a role in buffering vibration of the engine 1.
Optionally, a hydraulic cylinder port and a hydraulic cylinder cover are arranged at the upper end of the side wall of the hydraulic cylinder 302.
The cylinder port is used to inject hydraulic oil into the cylinder 302 or to take out waste oil in the cylinder 302, and the cylinder head is used to prevent hydraulic oil from oozing out. The quality of the hydraulic oil in the hydraulic cylinder 302 is reduced along with the lengthening of the service time, the fluidity of the hydraulic oil is weakened, and the shock absorption effect of the engine 1 is affected, so that the hydraulic oil needs to be replaced for a certain time. The hydraulic cylinder port is added to conveniently replace hydraulic oil, so that the damping effect is improved, and the abrasion of the engine 1 is reduced.
Here, the cylinder port is different from the opening described above.
Optionally, a buffer block is disposed on the lower surface of the base 301.
The base 301 is generally used for fixing the shock absorbing device of the engine 1 on the agricultural machine, so that the base 301 can inevitably collide with the agricultural machine, the impact force between the base 301 and the agricultural machine is reduced through the buffer block, the shock of the engine can be weakened, and the service lives of the agricultural machine, the engine and the shock absorbing device are prolonged.
Further, the buffer block may be a block structure having elasticity, such as a rubber block, a sponge block, or the like.
