Description

Technical Field

[0001] The utility model relates to the technical field of sand and stone separators, in particular to a shock-absorbing and noise-reducing mechanism for a sand and stone separator used for concrete processing. Background Art

[0002] The concrete sand and gravel separator is the core equipment of the concrete recycling system. It is mainly used to clean, separate and recycle the sewage from the tank truck and the sand and gravel in the residual concrete. The working reliability is its core screening system adopts the mixing principle of the mixer. The raw materials are tumbled and pushed by the continuous spiral blades and the friction between the materials in the mixing drum. The action is strong and natural, and the reliability is high. It has a high degree of integrity: except for the finished material stacking belt conveyor, all systems are integrated in an overall framework, which not only ensures the integrity of the equipment but also leaves appropriate maintenance and inspection space. The high degree of integrity facilitates storage or transfer transportation at the construction site, which is convenient and safe. When the machine is running, if any abnormal vibration or sound is found, the feeding should be stopped immediately. After the material in the box is drained, the motor should be stopped immediately, and the machine should be shut down for inspection. Only after the fault is eliminated can it continue to operate.

[0003] Before starting the machine, rotate the rotor by hand to check whether there are any abnormalities in the various parts of the machine. The user unit should install protective equipment on the V-belt according to the specific conditions on site before it can be operated. Repairs and cleaning work cannot be carried out during operation. It is strictly forbidden to start the machine for maintenance.

The user unit should install protective equipment on the V-belt according to the specific conditions on site before it can be operated. Repairs and cleaning work cannot be carried out during operation. It is strictly forbidden to start the machine for maintenance. The existing sand and stone separators are very noisy when working. Working in such a noisy environment for a long time will bring great harm to the physical and mental health of workers. Since the existing centrifuges do not have shock absorbing devices, the stability of the centrifuges is insufficient. In response to this phenomenon, we propose a shock absorbing and noise reduction mechanism for sand and stone separators for concrete processing. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock-absorbing and noise-reducing mechanism for a sand and stone separator for concrete processing, comprising a separator, a conveying cylinder is fixedly installed on the left side of the separator, an output shaft is inserted inside the conveying cylinder, a driving motor is fixedly connected to the left side of the output shaft, a sponge pad is fixedly installed inside the conveying cylinder, a conveyor belt is fixedly installed inside the conveying cylinder, a support seat is fixedly installed on the inner bottom wall of the conveying cylinder and located inside the conveyor belt, two supporting feet are fixedly installed on the bottom of the support seat, two first springs are fixedly installed on the top of the support seat, two connecting blocks are fixedly installed on the top of the two first springs, a shock-absorbing mechanism is arranged inside the conveyor belt, mounting blocks are movably installed on the tops of the two connecting blocks, and a gear is movably installed inside the conveying cylinder and located on the inner side of the conveyor belt;

[0006] The shock absorbing mechanism includes a limit block, two limit blocks are fixedly installed on the top of the support seat, limit grooves are provided on the left and right sides of the two limit blocks, support rods are inserted into the opposite sides of the two limit grooves, and clamping blocks are fixedly installed on the opposite sides of the two limit blocks, clamping blocks are fixedly installed on the tops of the two clamping blocks, mounting rods are inserted into the insides of the two clamping blocks, two second springs are sleeved on the outer surface of the support rod, and a push-pull block is fixedly installed on the outer surface of the support rod.

[0007] Furthermore, gears are movably installed on both left and right sides of the interior of the conveyor belt, and the second spring is located on the side opposite to the two clamping blocks and the push-pull block.

[0008] Furthermore, a clamping rod is fixedly installed at the bottom of the push-pull block, and the two mounting rods both penetrate the clamping block and extend to the interior of the clamping block.

[0009] Furthermore, the clamping rod at the bottom of the push-pull block passes through the support seat and extends to the inside of the support seat, and the left side of the conveying cylinder passes through the separator and extends to the inside of the separator.

[0010] Furthermore, the output shaft of the driving motor is connected to the gear transmission, and the width of the limiting groove is greater than the diameter of the supporting rod.

[0011] Furthermore, the tops of the two mounting blocks are in contact with the inner top wall of the conveyor belt, and a buffer groove is provided on the top of the support seat.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The shock-absorbing and noise-reducing mechanism of the sand and stone separator for concrete processing is provided with a shock-absorbing mechanism. When the conveying cylinder is subjected to pressure during transportation, the push-pull block moves up and down to drive the support rod. When the support rod moves upward, the space in the limit groove becomes smaller, so that the block is squeezed, and the mounting rod drives the second spring to perform reciprocating motion under the action of the spring torsion, thereby achieving a shock-absorbing effect. The existing separator does not have a shock-absorbing mechanism, so the stability of the centrifuge is insufficient. The design is simple to operate and has a clear principle. It can effectively solve the problem of insufficient stability of the centrifuge, thereby greatly improving the construction quality.

[0014] 2. By setting the sponge pad, when the separator makes noise during operation, the internal sponge pad is wrapped around the outer surface of the shock absorbing mechanism, which can better isolate the noise. The existing sand and gravel separator makes a lot of noise during operation. Working in such a noisy environment for a long time will cause great harm to the physical and mental health of workers. In order to effectively improve this situation, we have designed this sand and gravel separator for concrete processing. Shock-absorbing and noise reduction mechanism.

[0022] When implementing, follow these steps:

[0023] 1) First, by setting the shock absorbing mechanism 11, when the conveying cylinder 2 is under pressure during transportation, the push-pull block 119 moves up and down to drive the support rod 113;

[0024] 2) Then, when the support rod 113 moves upward, the space in the limiting groove 112 becomes smaller, so that the block 115 is squeezed;
