Description

TECHNICAL FIELD

[0001] The utility model relates to concrete processing technical field especially is related to a concrete anti -setting device. BACKGROUND

[0002] In the construction process, concrete as an important building material is widely used in various engineering. In order to ensure the quality and performance of concrete, it is very critical to prevent concrete from premature setting during transportation or storage. The existing concrete anti-setting method mainly includes regular stirring, adding anti-setting agent and other means, but these methods often have certain limitations.

[0003] The common concrete mixing equipment in the market at present adopts the mode of motor driving stirring shaft. Although this design can meet the basic stirring demand, in the long-time use process, single motor is easy to be damaged due to excessive load, leading to the maintenance of the whole equipment, which affects the construction progress.

[0004] Another commonly used method is to add anti-setting agent in concrete. Although this method can delay the setting time of concrete to a certain extent, the addition amount of anti-setting agent is difficult to control accurately, and too much or too little will affect the final performance of concrete. In addition, the use of anti-setting agent also increases the construction cost.

[0005] Chinese patent CN221659666U discloses a concrete anti-setting device, the top surface of the U-shaped frame is provided with an arc-shaped plate, the arc-shaped plate is provided with guide plates at both ends, the bottom surface of the storage tank is provided with an electromagnetic valve, the top surface of the support table is provided with a water tank, the top surface of the water tank is provided with a through pipe, the top surface of the through pipe is provided with a mounting seat, the mounting seat is provided with water guide pipes at both ends, and the front surface of the water tank is provided with a rubber plug. The concrete anti-setting device, through the sealing door at the back of the storage tank, the concrete enters the storage tank, and the heat preservation cotton inside the storage tank can keep the concrete fresh, and the concrete stored in the tank is in a sealed state, which can prevent excess air from entering the tank, thereby avoiding the setting of the concrete inside the storage tank. It can be seen that the above-mentioned prior art is to avoid the setting of concrete by stirring in the horizontal direction, but in actual use, water will gradually precipitate to the bottom of the storage tank, causing the concrete slurry in the storage tank to appear stratification, resulting in insufficient water content in the upper layer, which easily affects the later use of concrete SUMMARY

Increase torque, two motors working together can provide greater total torque, suitable for applications that require higher torque. In the case of needing to accelerate or decelerate quickly, two motors can reach the required speed and torque faster; 3. Improve accuracy, by synchronously controlling two motors, the position and speed of the rotating shaft 6 can be more accurately controlled, and the errors of the two motors can be offset, thereby improving the overall accuracy of the system.
