It should be noted that, above-mentioned dead man and the operation of smashing in advance only adopted a power supply promptly driving motor, design benefit, not only realized energy-conserving effect, but also reduced the utility model discloses a structural complexity, the shape design of triangle-shaped bat pole moreover can be patted all positions of cigarette rod basically, has still reduced the space that the bat pole occupied simultaneously.

4) The tobacco stems are crushed again, the inclined plates in the collecting box guide the tobacco stems to enable the tobacco stems to enter a discharge pipe at a discharge port and enter a conveying pipe from a first feed hopper of the conveying pipe, a conveying shaft in the conveying pipe is driven by a crushing motor to rotate and push and transfer the tobacco stems to a compression box, the tobacco stems are mutually extruded by a first spiral blade on the conveying shaft and a second spiral blade on the inner wall of the conveying pipe in the process, efficient crushing is realized, and meanwhile, a heating electric coil on the conveying pipe generates heat after being electrified, so that the tobacco stems can be dried;

it should also be noted that the second feed hopper arranged on the conveying pipe is used for introducing plastics, the plastics adopt waste mulching films uncovered before the tobacco leaves are harvested, and meanwhile, crushed plastic leatheroid, such as beverage bottles, pesticide bottles and the like, can be placed, and the plastics can be in full contact with the tobacco stems;

5) compressing, after a certain amount of mixture of the plastic and the tobacco rod scraps enters a compression box, starting a compression motor, driving an internal thread cylinder to rotate through a belt by the compression motor, enabling a screw rod to move linearly and pushing a fixing plate and a shifting plate to push the mixture to realize extrusion compression by the rotation of the internal thread cylinder, enabling a heating electric coil on the compression box to be electrified and heated to enable the interior of the compression box to be in a high-temperature state, melting the plastic in the mixture after double heating of a conveying pipe and the compression box sequentially, filling the plastic in the tobacco rod scraps, stopping heating the heating electric coil after compressing for a certain time, reducing the temperature of the compressed mixture, reshaping the melted plastic, and effectively bonding the powder and keeping the compressed mixture in a block shape; the door is then opened and the block falls onto a receiving station where it is collected. Then the compression motor reversal for the screw rod drives fixed plate and switch-plate and resets, because the conveyer pipe is still being pay-off in to the compression box at this moment, so meet the mixture that newly gets into in the compression box when the switch-plate and block the back, can take place to rotate around the pin joint, and then avoid the mixture. But when fixed plate and switch plate cooperation extrusion mixture, the setting of limiting plate on the fixed plate for the switch plate can't rotate towards the sleeve, can only realize the compression operation.

It should be noted that the compression process also realizes the packing operation, and simultaneously abandons the wrapping, thread rope winding and other modes in the prior art, thereby not only greatly simplifying the structure, but also because the finally obtained mixture is used as biomass fuel, the performance of the mixture cannot be influenced because the plastic in the mixture is also a combustible material, and the torn mulching film can be recycled, thereby achieving multiple purposes.
