As shown in fig. 4, two sliding blocks 14 and two sliding rails 15 are arranged in the shell 1, the sliding blocks 14 are slidably connected to the sliding rails 15, the length direction of the sliding rails 15 is perpendicular to the axial direction of the variable roller two 4, and the two sliding rails 15 are arranged at two ends of the variable roller two 4 in parallel. The slide block 14 is provided with a slide bar 16, the axis of the slide bar 16 extends along the up-down direction, and the mounting frame 13 is connected to the slide bar 16 in an up-down sliding manner.
As shown in fig. 2 and 4, the housing 1 is provided with two linear drives 17, and the linear drives 17 are air cylinders or hydraulic cylinders. The two linear drivers 17 respectively drive the two sliding blocks 14 to slide back and forth in the two sliding rails 15, so as to drive the mounting frame 13 and the variable roller two 4 to slide back and forth, namely the variable roller two 4 moves to one side far away from or close to the variable roller one 3.
As shown in fig. 2 and 4, the linear driver 17 drives the slider 14 to reciprocate, so as to drive the variable roller two 4 to swing left and right, thereby adjusting the width of the blanking channel. The swing of the variable roller II 4 with small amplitude is beneficial to breaking the stress balance among the concrete test blocks 6, so that the test block groups which may form an arch shape originally are separated in a loose way, and the blockage of a discharging channel is reduced. In addition, the swing of the second variable roller 4 is beneficial to applying a downward impact force to the contacted concrete test block 6, endowing the concrete test block with initial kinetic energy, and enabling the concrete test block 6 to smoothly enter the gap between the first roller tooth 32 and the second roller tooth 45, thereby being beneficial to improving the feeding speed and the crushing efficiency.
As shown in fig. 2 and 4, the roller shafts of the first variable roller 3 and the auxiliary roller 5 are both rotatably connected to the first connecting member 51, the roller shaft of the auxiliary roller 5 and the roller shaft of the crushing roller 2 are both rotatably connected to the second connecting member 52, and the roller shaft of the crushing roller 2 and the roller shaft of the second variable roller 4 are both rotatably connected to the third connecting member 53. The first connecting piece 51, the second connecting piece 52 and the third connecting piece 53 are all plate-shaped structures.
As shown in fig. 4, a sliding groove 73 is formed in a position, close to the second synchronous belt 722, of the housing 1, an adjusting block 74 is slidably provided in the sliding groove 73, and the sliding direction of the adjusting block 74 is identical to the sliding direction of the sliding block 14. The adjusting block 74 is rotatably connected with a tensioning wheel 75, the tensioning wheel 75 is in transmission connection with a synchronous belt II 722, and the adjusting block 74 and the sliding groove 73 are connected with a reset spring III 76.
As shown in fig. 2 and fig. 4, the tensioning wheel 75 is in transmission connection with the second synchronous belt 722, and when the second variable roller 4 moves to cause the second synchronous belt 722 to loosen, the third return spring 76 pushes the adjusting block 74 to slide, so as to drive the tensioning wheel 75 to jack the second synchronous belt 722, and automatically compensate the loosening amount of the second synchronous belt 722. When the second variable roller 4 moves reversely to tighten the second synchronous belt transmission structure 72, the tensioning wheel 75 is pushed by the second synchronous belt 722, and the third return spring 76 is compressed by the adjusting block 74, so that the belt body is prevented from being broken due to excessive stretching.
As shown in fig. 1 and 5, the auxiliary roller 5 and the crushing roller 2 are driven by a driving assembly 8, and the driving assembly 8 includes a driving motor three 81, a driving gear 82, a driven gear one 83 and a driven gear two 84.
As shown in fig. 1 and 5, a third driving motor 81 is provided in the housing 1, a driving gear 82 is mounted on an output shaft of the third driving motor 81, a first driven gear 83 is mounted on a roller shaft of the auxiliary roller 5, and a second driven gear 84 is mounted on a roller shaft of the crushing roller 2. The driving gear 82, the driven gear two 84 and the driven gear one 83 are sequentially in driving engagement.
As shown in fig. 1 and 5, the driving motor three 81 drives the driving gear 82 to rotate, and the driving gear 82, the driven gear two 84 and the driven gear one 83 are sequentially meshed in a transmission manner, so that the driven gear one 83 and the driven gear two 84 are driven to rotate, and the rotation of the auxiliary roller 5 and the crushing roller 2 is realized.
As shown in fig. 2 and 3, a first discharge channel is reserved between the auxiliary roller 5 and the crushing roller 2, and a second discharge channel is reserved between the crushing roller 2 and the variable roller 4. The first discharging channel is positioned below the second discharging channel and is far to the left. The variable roller two 4 is also provided with a plurality of crushing teeth 21 on its peripheral side.
As shown in fig. 2 and 3, after the concrete test block 6 is primarily crushed by the variable roller one 3 and the variable roller two 4, the sizes of the concrete test block 6 are different, and the concrete test block 6 with a smaller size can directly enter the subsequent process through the discharge channel one, so that the energy consumption waste caused by excessive crushing is avoided. The larger-sized concrete test block 6 cannot enter the first discharging channel, and is guided to the second discharging channel along with the accumulation of the larger-sized concrete test block 6 and the rotation of the crushing roller 2, and targeted secondary crushing is performed through the extrusion and shearing actions of the crushing roller 2 and the second variable roller 4, so that the crushed concrete test block 6 has uniform granularity. In addition, the first discharging channel and the second discharging channel are arranged, so that the invasion of the concrete test block 6 with a smaller size to the discharging channel can be reduced, the speed of feeding the concrete test block 6 with a larger size into the clamping area between the rollers can be increased, and the crushing efficiency can be improved.
The method for recycling waste building detection materials, which uses the waste building detection material recycling device of the embodiment, comprises the following steps:
The first step is that the concrete test block 6 falls into the blanking channel from the feed hopper 11, the first driving part 35 drives the first variable roller 3 to rotate, the convex part of the first cam 34 intermittently pushes the first roller teeth 32 on the first variable roller 3 to extend out, and the concrete test block 6 falling from the blanking channel is hit and crushed.
And secondly, the driving part II 7 drives the variable roller II 4 to rotate, the convex part of the cam II 46 pushes the stop block 43 on the variable roller II 4 to rotate around the hinge shaft 42, the stop block 43 stretches out, the concrete test block 6 hit by the roller tooth I32 impacts the roller tooth II 45, the crushing effect is improved, the concrete test block 6 is primarily crushed to a size suitable for efficient feeding and fine crushing, the crushing efficiency is improved, and meanwhile, the stretched stop block 43 can block the splashed concrete test block 6.
And thirdly, the linear driver 17 drives the sliding block 14 to reciprocate, so as to drive the variable roller II 4 to swing left and right, thereby adjusting the width of the blanking channel, being beneficial to reducing the blockage of the blanking channel, improving the feeding speed and improving the crushing efficiency.
And fourthly, the driving component 8 drives the crushing roller 2 and the auxiliary roller 5 to rotate, after the concrete test block 6 is primarily crushed by the variable roller I3 and the variable roller II 4, the concrete test block 6 with smaller size can directly enter the subsequent flow through the discharging channel I, and the concrete test block 6 with larger size can not enter the discharging channel I, and is guided to the discharging channel II along with the accumulation of the concrete test block 6 with larger size and the rotation of the crushing roller 2, the crushing roller 2 carries out secondary crushing on the concrete test block, and the crushed concrete test block 6 is discharged from the discharging hopper 12.
