If it is not cleaned in time, when the concrete is dry, it will affect the flatness of the vibration table, affect the stability of the concrete formwork during subsequent vibration operations and the horizontality of the vibration liquid level.

[0007] Preferably, four fixedly mounted vibration motors are arranged in a rectangle below the upper support seat, vibration table springs are arranged between the four corners below the upper support seat and the upper end of the support seat, and a shock-absorbing pad is arranged below the fixed seat.

[0008] Preferably, a first bubble level is fixedly installed at the middle position of one side of the lower support seat, a second bubble level is fixedly installed at the middle position of one side of the upper support seat, a first electric telescopic cylinder is arranged between the four corners below the support seat and the upper end of the fixed seat, and the upper and lower ends of the first electric telescopic cylinder are respectively rotatably connected to the fixed seat and the lower support seat through a universal shaft.

[0009] Preferably, a scraper mechanism transmission seat is provided below the scraper screw, and the scraper mechanism transmission seat is an L-shaped structure, a second electric telescopic cylinder is fixedly installed above one end of the scraper mechanism transmission seat, and a scraper mechanism fixed seat is fixedly installed above two of the second electric telescopic cylinders, and the scraper mechanism fixed seat is a U-shaped structure.

[0010] Preferably, a scraper fan is provided at the middle position above the scraper mechanism fixed seat, the air outlet end of the scraper fan is sealedly connected to the main air pipe, and the lower end of the main air pipe passes through the bottom of the scraper mechanism fixed seat and is sealedly connected to three branch air pipes, and the lower end of the branch air pipe is sealedly connected to a nozzle.

[0011] Preferably, two first scrapers and one second scraper are fixedly installed at the lower end of the inner side of the scraper mechanism fixing seat, and the second scraper is located between the two first scrapers, the first scraper and the second scraper are located on one side of the air distribution pipe, the upper ends of the first scraper and the second scraper are provided with a scraper fixing seat, and the scraper fixing seat is fixedly connected to the scraper mechanism fixing seat, and the lower ends of the first scraper and the second scraper are provided with a silicone plate, the silicone plate of the first scraper is an arc-shaped structure, and the middle position of the silicone plate is inclined away from the air distribution pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is cleaning, the second electric telescopic cylinder is extended, and the second electric telescopic cylinder drives the fixed seat of the scraper mechanism to move upward, so that the lower end surface of the silicone plate of the first scraper and the second scraper is at the same horizontal line with the upper end surface of the vibration placing table, and the scraper fan above the scraper mechanism is started, and the scraper fan absorbs air and blows it out through the main air pipe. The air enters the air distribution pipe through the main air pipe and then blows out from the nozzle. The ejected air blows to one side of the upper surface of the vibration placing table, and the scraper mechanism transmission seat is driven to move to the other side of the vibration placing table through the scraper screw rod. The nozzle blows the concrete on the upper surface of the vibration placing table, and the first scraper and the second scraper are moved. The silicone plate scrapes the concrete in turn. Due to the inclined setting of the silicone plate, the concrete is pushed to the middle position of the silicone plate while scraping. When the first scraper and the second scraper move to above the aggregate box, the concrete is pushed into the aggregate box, which solves the problem that the existing concrete vibration table can limit the vibration direction and prevent it from shaking horizontally. However, when vibrating in the up and down directions, some concrete will splash out and fall on the surface of the concrete vibration table. If it is not cleaned in time, when the concrete is dry, it will affect the flatness of the vibration table, the stability of the concrete formwork and the horizontality of the vibration liquid level during subsequent vibration operations.

[0014] 2. The horizontal state of the vibration placing table directly affects the horizontality of the concrete liquid surface after vibration. The utility model checks whether the first bubble level on the lower support seat and the second bubble level on the upper support seat are kept horizontal. When the lower support seat is not in a horizontal state, the height of the four corners of the lower support seat is adjusted by respectively extending and retracting the four first electric telescopic cylinders to keep the lower support seat in a horizontal state. When the first bubble level shows that it is horizontal but the second bubble level on the upper support seat shows that it is not horizontal, it means that the elastic force of the vibration table spring is uneven. The vibration table spring is replaced to keep the first bubble level and the second bubble level in a horizontal state, thereby ensuring the horizontal setting of the vibration placing table.

[0029] Working principle: When in use, first check whether the first bubble level 13 on the lower support seat 3 and the second bubble level 14 on the upper support seat 4 are kept horizontal. When the lower support seat 3 is not in a horizontal state, the four corner heights of the lower support seat 3 are adjusted by respectively extending and retracting the four first electric telescopic cylinders 11 to keep the lower support seat 3 in a horizontal state. When the first bubble level 13 shows horizontal but the second bubble level 14 on the upper support seat 4 shows uneven horizontality, it means that the elastic force of the vibration table spring 10 is uneven. The vibration table spring 10 is replaced to keep the first bubble level 13 and the second bubble level 14 both in a horizontal state, thereby keeping the vibration display table 5 level. During the vibration operation, the concrete mold to be vibrated is placed above the vibration display table 5, and the vibration motor 9 is started. The vibration motor 9 drives the vibration display table 5 to vibrate under the support of the vibration table spring 10. The vibrating vibration display table 5 discharges the air in the concrete in the upper concrete mold to make the concrete tighter. After the vibration is completed, the concrete mold is removed and the extension The second electric telescopic cylinder 17 drives the scraper mechanism fixing seat 18 to move upward, so that the lower end surface of the silicone plate 25 of the first scraper 19 and the second scraper 20 is at the same horizontal line with the upper end surface of the vibration placing table 5, and the scraper fan 12 above the scraper mechanism 7 is started. The scraper fan 12 absorbs air and blows it out through the main air pipe 22. The air enters the air distribution pipe 21 through the main air pipe 22 and then blows it out from the nozzle 23. The ejected air blows to one side of the upper surface of the vibration placing table 5, and drives the scraper mechanism transmission through the scraper screw 6. The seat 16 moves to the other side of the vibration placing table 5, and the nozzle 23 blows the concrete on the upper surface of the vibration placing table 5. The silicone plates 25 of the first scraper 19 and the second scraper 20 scrape the concrete in turn. Due to the inclined setting of the silicone plates 25, the concrete is pushed to the middle position of the silicone plates 25 while scraping. When the first scraper 19 and the second scraper 20 move to above the aggregate box 8, the concrete is pushed into the aggregate box 8, and the driving of the scraper screw 6 and the contraction of the second electric telescopic cylinder 17 realize the resetting of the scraper mechanism 7.
