However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an accelerating agent adding device, comprising a conveying mechanism 1, and a screening mechanism 2 is fixedly installed on the top of the conveying mechanism 1;

A belt 110 is movably sleeved between the outer walls of 07, two slide grooves 111 are provided on the top of the support frame 102, a movable plate 112 is movably embedded between the inner walls of the two slide grooves 111, two telescopic rods 113 are provided on one side of the outer wall of the movable plate 112, a weighing device 114 is movably inserted between the inner walls of the movable plate 112, a first gear 115 is fixedly sleeved on the outer wall of the weighing device 114, a second motor 116 is fixedly installed on one side of the outer wall of the movable plate 112, a second gear 117 is fixedly sleeved on the output end of the second motor 116, and the outer wall of the second gear 117 is meshingly connected with the outer wall of the first gear 115.

[0027] The effect achieved by the entire embodiment 1 is that when the quick-setting agent needs to be transported, the quick-setting agent first enters the inside of the conveying pipe 104 from the feeding pipe 105, and then, under the action of the first motor 108, the second transmission wheel 109 is driven to rotate, and at the same time, under the action of the belt 110 and the first transmission wheel 107, the spiral blade 106 is driven to rotate, so that the quick-setting agent is subjected to the force of rotation and extrusion and moves forward, and is sent out from the discharge pipe to the top of the weighing device 114, and the quick-setting agent is weighed by the weighing device 114, and then the data is transmitted to the signal processor, and the received signal is converted by the signal processor and transmitted to the inside of the controller, and then the data is transmitted to the signal processor.

By accurately controlling the mass of the accelerator added, the solidification effect of the concrete is greatly improved.

[0028] Embodiment 2, as Figure 2-Figure 4As shown, the screening mechanism 2 includes a mounting frame 201, a screening box 202 is fixedly mounted on the top of the mounting frame 201, two insertion grooves 203 are provided on the outer wall of the screening box 202, a round shaft 204 is movably inserted between the inner walls of the two insertion grooves 203, two convex blocks 205 are fixedly sleeved on the outer wall of the round shaft 204, a third motor 206 is fixedly mounted on one side of the outer wall of the screening box 202, and the output end of the third motor 206 is fixedly connected to the outer wall of the round shaft 204, four limit springs 207 are fixedly mounted on the bottom of the inner wall of the screening box 202, a filter plate 208 is fixedly mounted between the tops of the four limit springs 207, the top of the support frame 102 is fixedly connected to the bottom of the mounting frame 201, and the outer wall of the feed pipe 105 is fixedly inserted on the inner wall of the screening box 202.

[0029] The effect achieved by the entire embodiment 2 is that when the accelerating setting agent needs to be screened, the accelerating setting agent is first sent into the screening box 202 under the operation of the staff, and then the circular shaft 204 and the convex block 205 are driven to rotate under the action of the third motor 206, and the filter plate 208 is driven to vibrate up and down under the action of the limit spring 207 to screen the accelerating setting agent and prevent impurities from following the accelerating setting agent into the concrete, thereby greatly improving the practicability of the equipment.

[0030] Working principle: when it is necessary to add accelerator to the concrete, first send the accelerator into the screening box 202, and then under the operation of the staff, control the third motor 206 to drive the round shaft 204 to rotate, and drive the convex block 205 to rotate, and at the same time, under the action of the limit spring 207, drive the filter plate 208 to vibrate up and down inside the screening box 202, so as to vibrate and screen the accelerator to prevent impurities from entering the concrete. The screened accelerator reaches the inside of the conveying pipe 104 from the feed pipe 105, and then under the action of the first motor 108, drives the second transmission wheel 109 to rotate, and at the same time, under the action of the belt 110 and the first transmission wheel 107, drives the spiral blade 106 to rotate, so that the accelerator inside the conveying pipe 104 is subjected to the rotating extrusion force and moves forward, and then is sent out from the discharge pipe and reaches the top of the weighing device 114, and the accelerator is weighed by the weighing device 114, and the data is transmitted at the same time. The signal processor converts the received signal and transmits it to the controller. The required mass of the accelerating agent can be calculated by the algorithm preset in the controller. Finally, the control instruction is transmitted to the actuator, and the first motor 108 is controlled to stop working, thereby stopping the delivery of the accelerating agent. Then the telescopic rod 113 is controlled to drive the movable plate 112 to move to a suitable position in the slide groove 111, and then the second motor 116 is controlled to drive the second gear 117 to rotate. At the same time, under the action of the first gear 115, the weighing device 114 is driven to rotate 90 degrees counterclockwise, so that the weighed accelerating agent is sent into the concrete mixing device for mixing. After the addition of the accelerating agent is completed, the weighing device 114 is returned to the initial position under the cooperation of the weighing device 114, the signal processor, the controller and the actuator, and the first motor 108 is controlled to start moving, so as to deliver the accelerating agent again.
