By setting up a vibration damping mechanism one and a vibration damping mechanism two, the engine is first fixedly installed on the upper surface of the lower pressure plate. During operation, the engine vibrates, and the lower pressure plate vibrates along with the engine. The vibration generated by the lower pressure plate in the vertical direction is buffered and damped by the cooperation of spring one and the hydraulic cylinder assembly, thereby buffering and damping the vibration generated by the engine in the vertical direction, improving the vibration damping effect of the device. The vibration generated by the lower pressure plate in the horizontal direction is buffered and damped by the cooperation of spring two on both sides and movable plate one, and the vibration generated by the lower pressure plate in the horizontal direction is buffered and damped by the cooperation of spring three on both sides and movable plate two, thereby buffering and damping the vibration generated by the engine in the horizontal direction, further improving the vibration damping effect of the device.

[0016] 2. The present invention provides a vibration damping device and installation process for a micro-tiller engine and frame. By setting up a detection unit 1 and a detection unit 2, when the vibration amplitude generated by the engine in the horizontal direction is too large, the through groove on the sealing plate can be moved into the interior of the liquid storage tank 2, so that the liquid in the liquid storage tank 2 flows down into the observation box 2 through the through groove.

[0026] The housing 51 is a hollow structure with an open top and a closed bottom. A groove 58 is provided on the inner wall of the housing 51.

The bottom of the fourth connecting block 76 is fixedly connected to the straight plate 77, and the bottom of the straight plate 77 is fixedly connected to the slider 78. The slider 78 is slidably installed in the slide groove 58, ensuring that the second housing 71 can slide stably up and down on the outside of the first housing 51.

[0035] Four connecting plates 72 are fixedly connected to the outer side of housing 71. A spring 73 is connected to the lower surface of each connecting plate 72.

A push rod 75 is fixedly connected to the lower surface of each connecting plate 72. The push rod 75 is vertically positioned and movably passes through the connecting plate 74, with its lower end located below the connecting plate 74. A handrail 11 is provided on the frame 10.

[0036] The present invention also includes an installation process for a vibration damping device for a micro-tiller engine and frame. Based on the above-mentioned vibration damping device for a micro-tiller engine and frame, the installation process includes an engine 9, a frame 10, and the following steps: First, the bottom of housing 1 51 is fixedly installed on the frame 10. Then, the lower pressure plate 21 is placed on the top of housing 2 71. Then, the threaded rod 2 36 is aligned with the threaded hole 2 65. Then, the adjusting knob 37 is rotated to make the threaded rod 2 36 spirally inserted into the threaded hole 2 65. Then, the engine 9 is fixedly installed on the upper surface of the lower pressure plate 21 so that the engine 9 and the lower pressure plate 21 become a whole.

[0037] Working principle of this invention embodiment: When the engine 9 is operating, it will vibrate, and the lower pressure plate 21 will vibrate along with the engine 9. When the engine 9 vibrates vertically, the lower pressure plate 21 will press the housing 2 71 downwards repeatedly. The spring 4 73 can buffer and dampen the vibration generated by the lower pressure plate 21 in the vertical direction. At the same time, the cooperation between the spring 1 32 and the hydraulic cylinder assembly 34 can also buffer and dampen the vibration generated by the lower pressure plate 21 in the vertical direction, thereby buffering and damping the vibration generated by the engine 9 in the vertical direction, improving the vibration reduction effect of this device.

[0038] Since the threaded rod 36 is threaded into the threaded hole 65, when the engine 9 vibrates horizontally, the lower pressure plate 21 will cause the moving plate 63 to vibrate horizontally as well. The two movable plates 52 clamp the moving plate 63 tightly through the compression ball 69, and the two movable plates 55 clamp the moving plate 63 tightly through the compression ball 610. The vibration generated by the lower pressure plate 21 in the horizontal direction is buffered and damped by the cooperation of the two springs 53 on both sides and the movable plate 52, thereby buffering and damping the vibration generated by the engine 9 in the horizontal direction. The vibration generated by the lower pressure plate 21 in the horizontal direction is buffered and damped by the cooperation of the two springs 56 on both sides and the movable plate 55, thereby buffering and damping the vibration generated by the engine 9 in the horizontal direction. This further improves the vibration damping effect of the device.

[0039] When the engine 9 is fixedly installed on the upper surface of the lower pressure plate 21, due to the weight of the engine 9, the engine 9 will compress the spring 32 and the spring 73 downward through the lower pressure plate 21. The spring 73 can reduce the compression of the spring 32.

[0040] By rotating the adjustment knob 37, the threaded rod 36 is pulled out from the threaded hole 65, and then the lower pressure plate 21 can be removed from the top of the housing 71. This allows for checking whether there is hydraulic oil leakage in the hydraulic cylinder assembly 34, and also facilitates the replacement of the hydraulic cylinder assembly 34 with a new one, thus ensuring that the device can always maintain a good shock absorption effect.

[0041] In summary, by setting up vibration damping mechanism 1 2 and vibration damping mechanism 2 4, the engine 9 is first fixedly installed on the upper surface of the lower pressure plate 21. During operation, the engine 9 vibrates, and the lower pressure plate 21 vibrates along with it. The vibration generated by the lower pressure plate 21 in the vertical direction is buffered and damped by the cooperation of spring 1 32 and hydraulic cylinder assembly 34, thereby buffering and damping the vibration generated by the engine 9 in the vertical direction, improving the vibration damping effect of this device. Furthermore, the vibration generated by the lower pressure plate 21 in the horizontal direction is buffered and damped by the cooperation of spring 2 53 on both sides and movable plate 1 52, and the vibration generated by the lower pressure plate 21 in the horizontal direction is buffered and damped by the cooperation of spring 3 56 on both sides and movable plate 2 55, thereby buffering and damping the vibration generated by the engine 9 in the horizontal direction, further improving the vibration damping effect of this device. This effectively solves the technical problem in the prior art where the shock absorber installed at the connection between the engine and the frame can only dampen vibration in the vertical direction, resulting in poor vibration damping effect.

[0051] The outer side of the casing 841 is fixedly connected to the support plate 82. The inner wall of the casing 841 is fixedly connected to the liquid storage tank 842 and the observation box 843. The liquid storage tank 842 stores a liquid with good fluidity (such as water). The bottom of the liquid storage tank 842 is fixedly connected to the top of the observation box 843, and the liquid storage tank 842 and the observation box 843 are interconnected.

[0052] The top of observation box 2 843 is located inside shell 4 841, and observation box 2 843 penetrates shell 4 841. Most of the structure of observation box 2 843 is located on the outside of shell 4 841. Observation box 2 843 is made of transparent plastic to facilitate observation of its internal contents. Observation box 2 843 is equipped with a volume scale to facilitate observation of the amount of liquid inside.

[0053] A sealing tube 844 is fixedly connected to one outer side of the liquid storage tank 2 842. The sealing tube 844 is horizontally set and penetrates the housing 4 841. The end of the sealing tube 844 away from the liquid storage tank 2 842 is fixedly connected to the outer surface of the housing 1 51.

[0054] A limiting tube 845 is fixedly connected to the other outer side of the liquid storage tank 842. A delivery pipe 846 is fixedly connected to the top of the liquid storage tank 842, and the delivery pipe 846 is interconnected with the liquid storage tank 842. The end of the delivery pipe 846 away from the liquid storage tank 842 is fixedly connected to the bottom of the observation box 843, and the delivery pipe 846 is interconnected with the observation box 843. The delivery pipe 846 penetrates the housing 841. A delivery pump and an electric valve can be installed inside the delivery pipe 846. Only when the electric valve is opened to open the delivery pipe 846 and the delivery pump is started can the liquid in the observation box 843 flow into the liquid storage tank 842 through the delivery pipe 846.

[0055] A sealing plate 847 is slidably connected to the inner side of the sealing tube 844. The sealing plate 847 passes through the sealing tube 844 and is horizontally set. A through groove 848 is provided on the sealing plate 847. The sealing plate 847 movably passes through the housing 51.

[0056] A vertical plate 849 is fixedly connected to the end of the sealing plate 847 away from the sealing tube 844. The vertical plate 849 is located inside the housing 51. One of the two vertical plates 849 is fixedly connected to one of the two movable plates 52, and the other vertical plate 849 is fixedly connected to one of the two movable plates 55.

[0057] Working principle of this invention embodiment: When the engine 9 does not produce horizontal vibration, the through groove 848 on the sealing plate 847 is located inside the sealing tube 844, and the sealing plate 847 is horizontally blocked inside the liquid storage tank 842, so that the liquid in the liquid storage tank 842 cannot flow into the observation box 843.

[0058] When the engine 9 vibrates in the horizontal direction, ball 69 reciprocates to press movable plate 52, and ball 610 reciprocates to press movable plate 55. This causes movable plate 52 to move one sealing plate 847, which in turn causes movable plate 55 to move the other sealing plate 847. Therefore, when the vibration amplitude of the engine 9 in the horizontal direction is too large, the through groove 848 on the sealing plate 847 can be moved into the liquid storage tank 842. This allows the liquid in the liquid storage tank 842 to flow downward into the observation box 843 through the through groove 848. Therefore, when the vibration amplitude of the engine 9 in the horizontal direction is too large multiple times, the liquid in the observation box 843 will increase. By observing how much liquid is in the observation box 843, the user can easily detect whether the engine 9 is vibrating abnormally and perform timely maintenance, thus improving safety.

[0059] When the engine 9 does not produce vertical vibration, piston rod 3 838 will block the connection between hollow tube 833 and inclined tube 1 836. At the same time, piston rod 3 838 will also block the connection between hollow tube 833 and inclined tube 2 837, preventing the liquid in storage tank 1 832 from flowing into observation box 1 834.

[0060] When the engine 9 vibrates vertically, the lower pressure plate 21 presses the housing 71 downwards repeatedly, causing the push rod 75 to move up and down repeatedly, which in turn causes the push plate 839 to move up and down repeatedly, and the piston rod 838 to move up and down repeatedly. Therefore, when the vibration amplitude of the engine 9 in the vertical direction is too large, the piston rod 838 will move downwards to the lower side of the connection between the hollow tube 833 and the inclined tube 836, causing the liquid in the reservoir 832 to flow down into the observation box 834 through the inclined tube 836 and the inclined tube 837. Therefore, when the vibration amplitude of the engine 9 in the vertical direction is too large repeatedly, the liquid in the observation box 834 will increase. By observing how much liquid is in the observation box 834, the user can easily detect whether the engine 9 is vibrating abnormally and repair the engine 9 in a timely manner, further improving safety.

[0061] In summary, by setting up detection unit 1 83 and detection unit 2 84, when the vibration amplitude generated by the engine 9 in the horizontal direction is too large, the through groove 848 on the sealing plate 847 can be moved into the interior of the liquid storage tank 2 842, thereby allowing the liquid in the liquid storage tank 2 842 to flow downward into the observation box 2 843 through the through groove 848. By observing how much liquid is in the observation box 2 843, the user can promptly detect whether the engine 9 is vibrating abnormally, facilitating timely maintenance of the engine 9 and improving safety. When the vibration amplitude generated by the engine 9 in the vertical direction is too large, the piston rod 3 838 will move downward to the lower side of the connection between the hollow tube 833 and the inclined tube 1 836, thereby allowing the liquid in the liquid storage tank 1 832 to flow downward into the observation box 1 834 through the inclined tube 1 836 and the inclined tube 2 837. By observing how much liquid is in the observation box 1 834, the user can promptly detect whether the engine 9 is vibrating abnormally, facilitating timely maintenance of the engine 9 and further improving safety.
