[0030] The back of mounting bracket 1 is provided with a cleaning mechanism, the bottom of mounting bracket 1 is fixedly provided with a bottom mounting plate 11, the both ends of mounting bracket 1 are fixedly provided with side mounting plates 12, the bottom mounting plate 11 and the side mounting plates 12 are connected with the heat conducting bucket 2 through a driving mechanism, a controller is arranged on the mounting bracket 1, and the controller is electrically connected with the heating tubes 21, wherein the heating tubes 21 are copper heating tubes 21, the copper heating tubes 21 have excellent thermal conductivity and can rapidly conduct heat energy;

[0031] Since the side mounting plates 12 and the bottom mounting plate 11 are fixedly installed on the mounting bracket 1, the driving mechanism is connected with the bottom mounting plate 11, the side mounting plates 12 and the heat conducting bucket 2 respectively, the mounting bracket 1 can be driven to move forward through the driving mechanism, and the heat conducting bucket 2 can be driven to rotate synchronously; after the controller controls the plurality of heating tubes 21 to heat, the heating tubes 21 can transmit heat to the side wall of the heat conducting bucket 2, the heat conducting bucket 2 synchronously conducts heat to the asphalt overlay pavement layer, delays heat loss, enables an external paving vehicle to perform paving operation while the heat conducting bucket 2 transmits heat to the asphalt overlay pavement layer, and enables the bonding layer to be bonded with the old pavement;

[0032] As Figure 4 The driving mechanism includes a motor 31, a transmission rod 32 fixedly arranged in the middle of the heat conducting bucket 2 and a first guide wheel 33 arranged between the bottom mounting plate 11 and the side mounting plates 12, the motor 31 is electrically connected with the controller, the motor 31 is arranged on the outer side wall of one side mounting plate 12, and the output shaft of the motor 31 penetrates through the side mounting plate 12; the both ends of the transmission rod 32 penetrate out of the heat conducting bucket 2 and are connected with a first connecting rod 34 and a second connecting rod respectively;

[0033] A bearing is arranged on the inner side wall of the side mounting plate 12 close to the first connecting rod 34, one end of the first connecting rod 34 penetrates through the bottom mounting plate 11 and the first guide wheel 33 and is movably connected with the side mounting plate 12 through the bearing, and one end of the second connecting rod penetrates through the bottom mounting plate 11 and the first guide wheel 33 and is connected with the output shaft of the motor 31; one side of the first connecting rod 34 and the second connecting rod is fixedly connected with the inner cavity of the first guide wheel 33;

[0034] Specifically, the motor 31 is driven to rotate by the controller, and the output shaft of the motor 31 is fixedly connected to the second connecting rod through the side mounting plate 12, so as to drive the second connecting rod to rotate. The second connecting rod is fixedly connected to the inner cavity of the first guide wheel 33 and the transmission rod 32, so that the second connecting rod synchronously drives the first guide wheel 33 and the transmission rod 32 close to the motor 31 to rotate. The other end of the transmission rod 32 is connected to the first connecting rod 34, and the first connecting rod 34 is connected to the bearing of the first guide wheel 33, thereby driving the first connecting rod 34 and the first guide wheel 33 away from the motor 31 to rotate.
