Initial state: the slide block 20 closes the inner vent hole 15, the oblique head pin 18 is inserted into the first positioning hole 38 of the first rotating shaft 6, and the second rotating shaft 7 and the second turnover plate 10 are locked.
The working principle is as follows: when the spiral screw shaft 4 and the spiral blades 5 are driven by the motor 1 to rotate, air which is blown in by the air blower 14 and is heated by the air heating device 13 enters the inner cavities of the spiral screw shaft 4 and the spiral blades 5, and is blown out of the inner air vents 15 when the inner air vents are opened, so that the biomass is dried, and corresponding moisture is taken away by the outer air vents 12.
When the whole gravity control mechanism, i.e. the slider 20, the slanting head pin 18, etc. are located at the lower half portion of the machine body 11, the slider 20 will overcome the pulling force of the spring 21 under the action of gravity to drive the slanting head pin 18 to insert into the first positioning hole 38 of the first rotating shaft 6 along the guiding groove of the first rotating shaft 6. The sealing of the internal air vent 15 is realized, and the biomass materials between the hollow helical blades 5 are prevented from entering the hollow cavities in the hollow helical blades 5. Meanwhile, the control of the positioning locking of the first rotating shaft 6 is realized, and meanwhile, the first rotating shaft 6, the scraper 8 and the first turning plate 9 are fixedly connected, so that the control of the fixing locking of the scraper 8 and the first turning plate 9 is realized. With the insertion of the slant-end pin 18, the first round-head slider 22 is helped to slide in the first sliding groove 28 against the resistance of the first return spring 23, and the first push rod 24 is driven to press the first hydraulic push plate 26 into the first hydraulic groove 27 and into the oil path 25 through hydraulic oil. The hydraulic oil in the oil way 25 flows into the second hydraulic groove 37, and the second hydraulic push plate 36 is pushed to drive the second push rod 35 to push the second round-head slider 32 to be clamped into the second positioning hole 31 of the second rotating shaft 7 along the guide groove 30, and the second rotating shaft 7 is fixedly connected with the second turning plate 10, so that the locking control of the second turning plate 10 is realized. An angle is formed between the first flap 9 and the second flap 10, which can be a small chamber for transporting biomass material. With the rotation of the helical blade 5 driven by the hollow helical shaft 4, the gravity mechanism tilts continuously, the slide block 20 overcomes the resistance of the spring 21 continuously, the oblique head pin 18 is driven to be pulled out of the first positioning hole 38 of the first helical shaft 6, and finally the unlocking of the mechanism is realized. Meanwhile, due to the existence of the torsion spring 17 between the wall of the hollow helical blade 5 and the first rotating shaft 6, the first rotating shaft 6 is influenced by the rotating torque of the torsion spring 17, and the purpose of turning is achieved. Meanwhile, along with the extraction of the oblique head pin 18, the first round-head slider 22 starts to reset under the influence of the elastic force of the first return spring 23, at the moment, under the influence of the gravity of the biomass material between the first turning plate 9 and the second turning plate 10, the second turning plate 10 starts to drive the second rotating shaft 7 to rotate, the second rotating shaft 7 extrudes the second round-head slider 31 out of the second positioning hole 31 and extrudes the second round-head slider into the guide groove 30, and the second round-head slider 32 pushes the second push rod 38 to drive the second hydraulic push plate 36 to extrude hydraulic oil towards the direction of the machine body 11. Under the influence of the first return spring 23 and the pressure of hydraulic oil, the second rotating shaft 7 and the first turning plate 9 are unlocked completely, and because the second rotating shaft 7 and the second turning plate 10 are fixedly connected, the unlocking between the second turning plate 10 and the first turning plate 9 is also realized. At this time, under the influence of the rotation and twisting of the torsion spring 17 between the wall of the helical blade 5 and the first rotating shaft 6, the unlocked second turning plate 10 realizes a turning action, and the biomass material originally existing between the first turning plate 9 and the second turning plate 10 is turned over and scattered into the cavity space formed between the hollow helical blade 5 and the hollow helical blade. At this time, since the inner vent holes 15 of the sliders 20 are opened by the gravity, the air heated by the air heating device 13 blown by the blower 14 is blown out from the inner vent holes 15 through the hollow helical screw shaft 4 and the hollow helical blades 5, and the biomass material particles just turning up between the helical blades 5 are subjected to blowing drying. While the associated water vapor is carried out of the housing 11 via the outer vent 12.
Along with the rotation of the hollow helical blade 5, the slider 20 drives the oblique head pin 18 to be inserted into the first positioning hole 38 of the first rotating shaft 6 under the action of gravity and the spring 21, so that the locking and positioning of the first rotating shaft are realized, because the first rotating shaft 6, the scraper 8 and the first turning plate 9 are fixedly connected, the positioning and locking control of the first turning plate 9 and the scraper 8 is realized at the same time, at the moment, because the oblique head pin 18 is inserted, the first round head slider 22 is extruded by the oblique head pin 18, the first push rod 24 is pushed to drive the first hydraulic push plate 26 to extrude hydraulic oil into the oil path 25, the hydraulic oil enters the second hydraulic groove 37 where the second hydraulic push plate 36 is located through the first rotating shaft 6 and the first turning plate 9 in the oil path 25, the second push rod 35 is pushed to drive the second round head slider 32 to overcome the resistance of the second return spring 33, and the second round head slider 32 is clamped into the second positioning hole 31 of the second rotating shaft 7 along the guide groove 30, so that the second rotating shaft 7 is fixedly connected with the second turning plate 10. A fixed locking of the second flap 10 is thus also achieved.
