Principle of operation
Before the waste mulching film recovery pretreatment system is used for carrying out recovery pretreatment on the waste mulching film, the system is checked. Firstly, whether each component of the system is intact or not is checked, the connection between the components is ensured to be intact and effective, and the system can be ensured to normally operate and work.
Waste mulching films are put into the feeding opening 13, the first motor 11 is turned on, the first motor 11 drives the first transmission belt 116 and drives the first belt wheel 115 to rotate, and meanwhile, the crushing toothed cutter 113 on the first transmission shaft 114 is driven to crush the waste mulching films.
The switch of the priming pump 15 is turned on, the power of the priming pump 15 is increased, so that water flows into the second water through pipe 131 quickly, the water entering the first water inlet pipe 118 presses the first water control valve 201 to the second shell 120, the upper water inlet 214 is opened, the lower water inlet 216 is closed, and the water flows into the upper water through pipe 215 and enters the sprayer 312 through the first water through pipe 311. At the same time, the first water control valve 201 presses down the movable pressing piece 221, so that the upper movable bead 223 presses down the connecting rod 224, and presses out the separating plate 319 through the lower movable bead 316. The shredded mulching film enters the cleaning and separating module 3, and the sprayed water hits the wall of the second casing 120, wherein the soil particles flow down onto the separating plate 319 along with the water flow direction, and flow into the first casing 111, and enter the water filtering standing groove 5 through the water outlet pipe 132.
Reducing the power of priming pump 15 reduces the water flow, first water control valve 201 is pushed back by the spring, so that lower water inlet 216 is opened, upper water inlet 214 is closed, and movable pressing block 221 is restored to enable separating plate 319 to be restored to close separating port 317. At this time, the water entering the lower water pipe 217 flows out from the first water outlet 220 to wash the chopped mulching film to the bottom of the second housing 120, the water flows into the water filtering static tank 5 through the water filtering net 135 and the second water outlet 134, and the chopped waste mulching film is sent to the drying chamber 14 by the screw propeller 130.
When the waste mulching film fragments pass through the discharge pipe 322, the discharge pipe 322 rotates to enable the scattering rod 323 to scatter and scatter the waste mulching film fragments, and meanwhile, the heating motor 16 blows hot air into the drying chamber 14 through the ventilation pipe 138 through the air blowing port 141 to dry the waste mulching film fragments.
After the waste mulching film recycling and pretreating system finishes the waste mulching film pretreating work, dried waste mulching film fragments are taken out from the first discharge hole 7, and all working parts are cleaned.
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.
