[0031] In the present invention, the second shock absorbing mechanism includes: a connecting block 8, four first connecting columns 9, four connecting rods 10, four second connecting columns 11, eight sliding blocks 12 and eight first shock absorbing springs 13;

[0032] The connecting block 8 is arranged between the four dampers 5 and is fixedly connected to the supporting platform 3. A first cross-shaped groove is provided on the supporting platform 3. The four first connecting columns 9 are all rotatably arranged in the first cross-shaped groove.

[0034] It should be noted that the specific type of damper 5 to be used is selected by relevant technicians familiar with this field, and the above-mentioned damper 5 belongs to the existing technology and will not be described in detail in this solution.

[0035] The working principle of this utility model:

[0036] The mixing mechanism used in the present invention is the existing technology, which includes a mixing tank, a motor, a transmission belt, a transmission wheel, a transmission shaft, and a support block. The support block is fixedly connected to the upper end of the support frame 1. The connection methods of the above-mentioned other structures are connection methods known to those skilled in the art. This solution will not be repeated. First, the equipment that needs electricity is externally connected to the power supply, and the concrete is placed in the mixing mechanism for mixing. At this time, the mixing mechanism is in operation, generating vibration and transmitting it downward through the support frame 1. The support frame 1 transmits the vibration force to the support platform 3, and transmits it downward through the vibration platform 3. Finally, the vibration force is distributed and damped by the volute spring 7, the first shock-absorbing spring 13 and the second shock-absorbing spring. The vibration force is transmitted to the volute spring 7. Because it is arranged in a small upper and large lower shape, it can better dissipate the impact force. When the four corners of the support platform 3 are unevenly stressed, it will not produce too much deformation, and can better perform shock absorption. When the volute spring 7 and the second shock-absorbing spring 14 are subjected to the vibration force, they will first be compressed. When the volute spring 7 and the second shock-absorbing spring 14 rebound, the damper 5 plays a role, so that The rebound force of the spiral spring 7 and the second shock-absorbing spring 14 is used to restore the resetting force of the damper 5, so that the spiral spring 7 and the second shock-absorbing spring 14 rebound smoothly. When the first shock-absorbing spring 13 is affected by the vibration force, the first shock-absorbing spring 13 will be compressed along with the shape of the sliding groove, thereby changing the direction of the vibration force and dispersing the vibration force. The retraction of the first shock-absorbing spring 13 drives the sliding block 12 to move, and the movement of the sliding block 12 drives the second connecting column 12 to move together. One end of the second connecting column moves, causing the connecting rod 10 to move at a certain angle. The degree of displacement causes the connecting block 8 to move downward. When the first shock-absorbing spring 13 rebounds, the connecting block 8 moves upward. When the supporting platform 3 is affected by the vibration force, the damper 5, base 6, spiral spring 7, connecting block 8, first connecting column 9, connecting rod 10, second connecting column 11, sliding block 12, first shock-absorbing spring 13 and second shock-absorbing spring 14 cooperate with each other to share the vibration force and reduce the impact of the vibration, thereby reducing the loosening of parts on the mixer, extending the service life of the equipment and reducing the cost of using the equipment.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
