[0030] Example 1, as Figures 1-5 shown, a bottom sealing plate assembly includes a plate body 1. A plurality of mounting blocks 4 are fixedly connected to the outer surface of the plate body 1. Mounting holes are formed in the outer surface of the mounting blocks 4. A buffer assembly 2 is arranged on one side of the plate body 1. The buffer assembly 2 includes a collar 21. The collar 21 is made of rubber. The top end of the collar 21 is fixedly connected to the bottom end of the plate body 1. A circular plate 22 is fixedly connected to the inner wall of the collar 21. A plurality of through holes 26 are formed in the outer surface of the circular plate 22. A round rod 23 is slidably connected to the inner wall of the through hole 26. The bottom end of the round rod 23 is fixedly connected to a round block 24. One side of the round block 24 is fixedly connected to one side of the inner wall of the collar 21. A first spring 25 is arranged on one side of the round block 24. The upper and lower ends of the first spring 25 are respectively fixedly connected to the top end of the round block 24 and the bottom end of the circular plate 22. By providing the collar 21, when installing the plate body 1, the plate body 1 is installed at the bottom of the excavator through the mounting blocks 4. During the walking process of the excavator, when stones and other sundries hit the surface of the rubber collar 21, the rubber collar 21 will deform inward, pushing the round block 24 on one side of the inner wall of the collar 21 to make the round rod 23 slide upward on the inner wall of the through hole 26 and compress the first spring 25 on the outer surface of the round rod 23, buffering and weakening the impact force received on the outside of the collar 21. By providing the buffer assembly 2, by arranging the rubber collar 21 below the plate body 1, it is possible to avoid direct collision on the surface of the plate body 1. When the rubber collar 21 is hit, it will deform inward, and the outward thrust of the first spring 25 on the outer surface of the round rod 23 will further buffer the impact force, as much as possible to prevent the plate body 1 from deforming due to external force and affecting the normal use of the plate body 1.
[0031] Referring to Figures 2-5 shown, in this implementation: a rectangular groove 28 is formed in the outer surface of the round rod 23. Two convex blocks 27 are fixedly connected to the inner wall of the through hole 26. When the round rod 23 slides on the inner wall of the through hole 26, the two convex blocks 27 on the inner wall of the through hole 26 will slide inside the rectangular groove 28 on the outer surface of the round rod 23, further restricting the angle between the round rod 23 and the through hole 26 and the collar 21, as much as possible to prevent the reset position of the round rod 23 from deviating after moving. The top end of the round rod 23 is fixedly connected to a top block 29. The top block 29 is a rubber block made of rubber. When the round rod 23 moves upward, the top block 29 will contact the bottom end of the circular plate 22. The rubber top block 29 can further buffer when the round rod 23 contacts the circular plate 22, improving the buffering effect of the buffer assembly 2.
[0032] Referring to Figures 2-5As shown in the figure, in this embodiment: A reinforcing edge 210 is fixedly connected to the bottom end of the collar 21. The reinforcing edge 210 is made of nylon material. By setting the nylon reinforcing edge 210, the edge surface of the bottom end of the collar 21 can be strengthened, and as much as possible, the wear and breakage of the edge of the collar 21 can be avoided, which affects the normal use of the buffer assembly 2. A number of reinforcing rings 211 are fixedly connected to the bottom end of the collar 21. The reinforcing rings 211 are made of metal iron. By setting the reinforcing rings 211, the outer surface shape of the collar 21 can be further strengthened, and the stability of the outer surface structure of the collar 21 when stressed can be improved.
[0033] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in the figure, in this embodiment: A positioning assembly 3 is arranged on the outer surface of the mounting block 4. The positioning assembly 3 includes a groove block 31. One side of the groove block 31 is fixedly connected to one side of the mounting block 4. A clamping groove is provided on one side of the groove block 31. A rotating block 32 is rotatably connected to one side of the mounting block 4. A second spring 33 is arranged inside the rotating block 32. A slider 34 is slidably connected to the inner wall of the rotating block 32. Two ends of the second spring 33 are respectively fixedly connected to one side of the slider 34 and one side of the inner wall of the rotating block 32. After connecting the plate body 1 to the excavator base through a bolt passing through the mounting hole on the outer surface of the mounting block 4, the rotating block 32 can be pushed to rotate towards the groove block 31. The slider 34 is pressed to retract the slider 34 into the rotating block 32 and compress the second spring 33. When the rotating block 32 rotates to one side of the groove block 31, the slider 34 is released to enable the second spring 33 to return to its original state and push the slider 34 to move outwards and insert into the clamping groove on the outer surface of the groove block 31, clamping the rotating block 32 at the bottom end of the bolt, strengthening the connection between the bolt, the mounting block 4 and the excavator base, and as much as possible, avoiding the loosening of the installation of the bolt and the plate body 1 caused by the vibration during the operation of the excavator.
[0034] Referring to Figure 2 , Figure 3 and Figure 6 As shown in the figure, in this embodiment: A number of convex strips 35 are fixedly connected to the top end of the slider 34. The convex strips 35 are rubber strips made of rubber material. The convex strips 35 are linearly distributed on the outer surface of the slider 34. By setting the rubber convex strips 35, the friction force when the slider 34 is inserted into the groove block 31 and contacts the inner wall of the groove block 31 can be increased, making it difficult for the rotating block 32 to slide out of the groove block 31. A sliding groove 36 is provided at the top end of the rotating block 32. A convex rod 37 is fixedly connected to the top end of the slider 34. The outer surface of the convex rod 37 slides on the inner wall of the sliding groove 36. When removing the plate body 1, the convex rod 37 can be pushed to slide on the inner wall of the sliding groove 36 to drive the slider 34 to retract into the rotating block 32, facilitating the rotation of the rotating block 32 to remove the bolt.
[0035] Working principle: When installing the bottom sealing plate of the excavator, the plate body 1 is attached to the bottom of the excavator, so that the mounting holes on the outer surface of the mounting block 4 are aligned with the threaded holes on the excavator base. Multiple bolts are passed through the mounting holes on the outer surface of the mounting block 4 to connect the plate body 1 and the buffer assembly 2 to the excavator. Then, the rotating blocks 32 on the outer surface of each mounting block 4 are respectively pushed to rotate towards the slot block 31. The slider 34 is pressed to retract the slider 34 into the interior of the rotating block 32 and compress the second spring 33. When the rotating block 32 rotates to one side of the slot block 31, the slider 34 is released to enable the second spring 33 to return to its original state and push the slider 34 to move outwards and insert into the card slot on the outer surface of the slot block 31, clamping the rotating block 32 at the bottom end of the bolt to reinforce the connection between the bolt and the mounting block 4 and the excavator base. During the walking of the excavator, when stones and other sundries impact the surface of the rubber sleeve ring 21, the rubber sleeve ring 21 will deform inwards, pushing the round block 24 on one side of the inner wall of the sleeve ring 21 to make the round rod 23 slide upwards on the inner wall of the through hole 26 and compress the first spring 25 on the outer surface of the round rod 23, buffering and weakening the impact force received on the outside of the sleeve ring 21.
