When a mixture formed by new asphalt, old asphalt and reclaimed liquid is poured into the crushing cavity 102, the mixture falls on the sieving net 124 at the moment, the output shaft of the first driving motor 92 rotates and drives the cam 126 to rotate, the convex part of the cam 126 rotates to be contacted with the contact rod 125 and continues to rotate, the contact rod 125 can be driven to move backwards, the contact rod 125 moves backwards to drive the sieving net 124 to move backwards, the return spring 123 is stretched, when the cam 126 rotates to be not contacted with the contact rod 125, the contact rod 125 and the sieving net 124 can move forwards under the action of the return spring 123, so that the sieving net 124 can move forwards and backwards, the mixture capable of passing through the sieving net 124 can fall on the crushing cutter 108 to be crushed, and the mixture capable of passing through can stay on the sieving net 124, so that the sieved mixture can be sieved, and the time for melting the new and old asphalt is prevented from being influenced, also can avoid having the bold mixture to smash the back still great, when dropping and carrying in crushing chamber 102 bottom, can cause the jam to charge-in pipeline 41, when new and old pitch melts and finishes, when the device is no longer in operation, the staff to the residue on screening net 124 clear up can.

Still including regenerant input mechanism 13, regenerant input mechanism 13 is including installing support 131, place jar 132, first sealed spiral cover 133, pipeline 134, connecting rod 135, stifled post 136 and buffer spring 137, the symmetry is equipped with installing support 131 through the mode of screw installation around the middle of machine case 1 top, be connected with through the mode of screw installation between the installing support 131 upper portion and place jar 132, it is equipped with first sealed spiral cover 133 to place jar 132 upside rotary type, it is connected with pipeline 134 to place between jar 132 bottom front side and the mixing chamber 4, sifting net 124 right side is equipped with connecting rod 135 through the welded mode, connecting rod 135 upper portion is equipped with stifled post 136, it is connected with pipeline 134 to block up post 136 and pipeline 134 sliding type, be connected with buffer spring 137 between blockking post 136 front side and pipeline 134, buffer spring 137 winds on stifled post 136.

The worker can rotate the first sealing cap 133 to separate from the placing tank 132, and can pour the regenerated liquid into the placing tank 132, so that the regenerated liquid is not required to be directly poured onto the un-crushed new and old asphalt, then the first sealing cap 133 is rotated back to the placing tank 132, the sieving net 124 moves backwards to drive the connecting rod 135 to move backwards, the connecting rod 135 moves backwards to drive the blocking column 136 to move backwards, the buffer spring 137 is compressed, the blocking column 136 moves backwards to stop the conveying pipeline 134, the regenerated liquid in the placing tank 132 can flow into the mixing cavity 4 through the conveying pipeline 134 so as to be mixed with the new and old asphalt, when the sieving net 124 moves forwards to drive the connecting rod 135 and the blocking column 136 to move forwards, the buffer spring 137 resets, the blocking column 136 moves forwards to stop the conveying pipeline 134 again, the regenerated liquid does not flow out any more, and the regenerated liquid can intermittently flow onto the new and old asphalt, avoid directly pouring the reclaimed liquid on new and old pitch, the volume of pouring is too much and causes the waste, and the volume of pouring is too little makes the mixed pitch result of use not good.

The device is characterized by further comprising a control box 2, the control box 2 is arranged on the left front side of the top of the case 1, a switching power supply, a control module and a power supply module are arranged in the control box 2, the switching power supply supplies power to a petroleum asphalt regenerating device capable of monitoring temperature, the output end of the switching power supply is electrically connected with the power supply module, the power supply module is connected with a power supply main switch through a circuit, the control module is electrically connected with the power supply module, and the control module is connected with a DS1302 clock circuit and a 24C02 circuit; the LCD display screen 8, the control switch 7, the first temperature sensor 94, the second temperature sensor 109 and the dust sensor 144 are electrically connected with the control module, and the heating plate 6, the first driving motor 92, the second driving motor 105 and the fan 143 are connected with the control module through peripheral circuits.

Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
