Principle of operation

After the main motor 11 is started, the fan motor 61 positioned at the lower bottom surface of the equipment shell 10 is started, the fan shaft 18 positioned above the fan motor 61 is rotated, the rotation of the fan shaft 18 rotates the fan blades 19 to generate wind power, the air suction holes 27 positioned below the fan blades 19 begin to suck air inside the upper part of the equipment shell 10 through the main air suction channel 46 due to the action of the fan blades 19, and at the moment, the nylon hook plate 33 is placed, and the suction cups 30 positioned above the nylon hook plate 33 are sucked;

the operator puts the stem of hemp which finishes retting treatment into the taper mouth 16, the two drying rollers 15 extrude to discharge the waste retting liquid, the waste retting liquid drops under the extrusion of the drying rollers 15 and flows into the waste liquid tank 14 to be collected, and the heat generated by the main motor 11 during working enters the drying roller cavity 58 through the heat discharging pipe 60, enters the drying inner pipe 55 through the drying roller cavity 58 and then is discharged to the surface of the sponge 53 to achieve the drying effect;

after the hemp stalks are extruded, drained and dried by the drying roller 15, the hemp stalks enter the equipment shell 10, at the moment, the pressure-bearing roller 44 in the equipment shell 10 continuously rotates under the action of the main motor 11, the first extrusion roller 65 and the pressure-bearing roller 44 are connected by a gear to rotate, and then crushing is started, and meanwhile, due to the rotation of the extrusion roller shaft 36, the inclined bulges at the two sides of the first extrusion roller 65 and the pressure-bearing roller 44 are in contact with the first extrusion roller 65 and the top post 49 at the outer side of the pressure-bearing roller 44, so that horizontal displacement is repeatedly generated, and a finer crushing effect is achieved;

at this time, the fan shaft 18 at the bottom of the device continuously rotates under the action of the fan motor 61 and conveys small wind upwards, wood chips generated by the upper hemp stems under the action of the first squeezing roller 65 and the pressure-bearing roller 44 fall above the fine-hole sieve plate 62 to be collected, and fine short fibers generated by hemp beating are blown by wind to fly above the device shell 10 and are hooked and collected by the nylon hook plate 33;

because the air suction holes 27 inside the fan cover 20 continuously draw air through the main air suction passage 46 under the action of the fan blades 19, the cavity between the sliding sleeve 37 and the intermittent sleeve 38 is short of air, the extrusion roller air suction passage 64 and the intermittent sleeve air suction passage 41 are intermittently aligned to generate a slightly large suction force along with the rotation of the extrusion roller shaft 36, and simultaneously, the crushed hemp stems cannot immediately droop under the combined action of the lower fan blades 19, so that the hemp stems can smoothly enter between the second extrusion roller 42 and the pressure-bearing roller 44 for secondary crushing;

the fibrilia which is scutched finally falls into the upper part of the transmission belt 26 and is conveyed out of the device to enter the collecting barrel 21 to be collected under the action of the transmission belt 26, and an operator can open the collecting box door 22 at regular time to replace the collecting barrel 21;

after enough short fibers are collected by the nylon hook plate 33 located above the inside of the equipment shell 10, the nylon hook plate will gradually sink under the action of gravity, the compression head 50 is pressed to enable the compression spring 51 located behind the compression head 50 to gradually contract, the compression head 50 retreats to drive the linkage rod 66 to move, the air baffle plate 32 is pulled to squeeze the air suction branch pipe 29 to reduce the suction force of the suction cup 30, finally, the nylon hook plate 33 falls off and slides out of the equipment shell 10 due to the slope action part located below the nylon hook plate 33, at the moment, the detection sensor 67 located on the surface of the nylon hook plate opening 17 detects the nylon hook plate 33 and sends a signal to halt the operation of the main motor 11, and an operator waits for the nylon hook plate 33 to be replaced so as to continue to operate.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
