[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1-4As shown, a device for crushing raw materials of autoclaved aerated blocks comprises a support frame 1, a crushing box 2 is provided on the support frame 1, two crushing rollers 3 are provided inside the crushing box 2, the two crushing rollers 3 are provided with crushing teeth 4 that mesh with each other, and one end of the two crushing rollers 3 is provided with gears 5 that mesh with each other, a reducer 6 is provided on the support frame 1, and a motor 7 is also provided on the support frame 1. The motor 7 and the input end of the reducer 6 are driven by a belt, and the output end of the reducer 6 is fixedly connected to one of the crushing rollers 3. A feeding box 8 is provided on the crushing box 2, and a pressing plate 9 is provided inside the feeding box 8. One end of the pressure plate 9 is rotatably connected to the feeding box 8, and the other end of the feeding box 8 is provided with a side rod 10. The outer surface of the feeding box 8 is provided with an arc groove for the movement of the side rod 10. The lower surface of the pressure plate 9 is evenly provided with pressure teeth 11. The shortest distance between the lowermost pressure tooth 11 and the inner bottom surface of the feeding box 8 is smaller than the shortest distance between the uppermost pressure tooth 11 and the inner bottom surface of the feeding box 8. A cylinder 12 is provided on the support frame 1, and the output end of the cylinder 12 is provided with a slider 13 slidably connected to the support frame 1, and also includes a connecting rod 14, and the two ends of the connecting rod 14 are rotatably connected to the side rod 10 and the slider 13 respectively.
[0018] When the slag material is crushed, the slag material is put into the feeding box 8, which is tilted. The smaller slag materials entering the feeding box 8 can directly pass through the feeding box 8 and enter the crushing box 2. At the same time, the motor 7 is started, and the motor 7 drives the reducer 6 to operate through the belt transmission. The output end of the reducer 6 drives one of the crushing rollers 3 to rotate, and drives the crushing teeth 4 on the crushing roller 3 to engage through the gears 5 on the two crushing rollers 3 to crush the slag material in the crushing box 2. As for the larger slag material, it is stuck between the pressing teeth 11 and the inner bottom surface of the feeding box 8. When it is necessary to crush the large pieces of slag in this part, During crushing, it is first necessary to crush it into smaller pieces of slag. Specifically, the cylinder 12 is started, the output end of the cylinder 12 retracts and drives the slider 13 to move downward, and the slider 13 drives the side rod 10 to move along the arc groove on the feeding box 8 through the connecting rod 14, and at the same time drives the pressure plate 9 to rotate. When the pressure plate 9 rotates, the large pieces of slag on the bottom of the feeding box 8 are crushed into smaller pieces of slag material through the pressure teeth 11, and then the output end of the cylinder 12 is controlled to extend, so that the pressure plate 9 rotates upward, and the distance between the pressure plate 9 and the bottom of the feeding box 8 increases. The slag crushed by the pressure teeth 11 continues to enter the crushing box 2 along the bottom of the feeding box 8 for further crushing.
[0019] Furthermore, vertical rods 15 are arranged at intervals on the inner top wall of the feeding box 8, and through grooves for the vertical rods 15 to pass through are evenly opened on the pressure plate 9. When the pressure plate 9 rotates, the pressure plate 9 does not contact the vertical rods 15. The vertical rods 15 can intercept the slag blocks that pass through the pressing teeth 11 but are still large in volume, so that the volume of part of the slag can be further reduced by the extrusion of the pressing teeth 11, which is beneficial to improving the subsequent crushing efficiency and crushing efficiency.
[0020] Furthermore, when the pressing teeth 11 contact the inner bottom surface of the feeding box 8, the lower surface of the pressing plate 9 is parallel to the inner bottom surface of the feeding box 8, so that the slag blocks between the pressing plate 9 and the inner bottom surface of the feeding box 8 can be crushed into roughly the same state, so that the size of the slag material fed from the feeding box 8 into the crushing box 2 is roughly equal.
[0021] Furthermore, the vertical rod 15 is made of rubber. As the slag material is continuously added, when a collision occurs with the vertical rod 15, the vertical rod 15 can return to its original shape, so that the vertical rod 15 can play a blocking role for a long time.
[0022] Furthermore, a vibration motor 16 is provided on the lower surface of the feeding box 8 to accelerate the speed at which the slag material in the feeding box 8 enters the crushing box 2 and prevent the slag material from accumulating in the feeding box 8 .
[0023] When the device is in use, it can crush larger pieces of slag material into smaller pieces of slag in advance to avoid the larger pieces of slag existing in the crushing box 2 for a long time and occupying the crushing channel, thereby improving the crushing efficiency of the slag and having a good use effect.
[0024] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
