When the original wood Cheng Wuliao separating and mashing device is used, materials are conveyed into the feed inlet 3 through a conveying belt once, the materials can fall onto the two mashing rollers 5 in sequence, the driving motor 6 can drive the two rotating shafts 4 and the two mashing rollers 5 to rotate through the two transmission gears 7, the two mashing rollers 5 can crush the materials, the crushed materials can fall to the inner bottom of the circular screen 12, the circular screen 12 can separate large particles in the materials, the rotating shaft 4 can drive the second rotating rod 14 to rotate through the chain transmission 17, the second rotating rod 14 can drive the large gear 16 and the rotating disc 9 to rotate through the small gear 15, the rotating disc 9 can drive the circular screen 12 to synchronously rotate, the rotating circular screen 12 can enable the materials positioned at the inner bottom to continuously overturn, and accordingly the efficiency of separating the materials can be improved, the round screen 12 rotating to the top of the processing box 1 can reversely pour out the materials blocked on the meshes and pour back to the two mashing rollers 5, so that the separation efficiency is prevented from being influenced by the fact that the round screen 12 is blocked by the materials for a long time, the automatic dredging work of the round screen 12 is completed, the two mashing rollers 5 can crush the materials which are easy to block the meshes again, so that the blocked materials are automatically recycled, and when the round screen 12 rotates, the round screen 12 can drive the large-particle materials to drive the inner top of the processing box 1 through the inclined plate 33 and pour back to the space between the two mashing rollers 5 to crush again, so that the large-particle materials are automatically recovered and crushed, and the materials which penetrate through the round screen 12 are finally discharged from the discharge port 2 at the bottom of the processing box 1, and in practice, the inclined plate 33 inclines towards the rotating direction of the round screen 12;
in practice, the materials are generally different in size, and some materials are heavier in weight, when the materials are fed, the materials can cause great impact force to the mashing rollers 5, then when the materials continuously enter the feed inlet 3, the materials can firstly fall into the guide pipes 19, then fall onto the two mashing rollers 5 from the guide pipes 19, the buffer springs 20 at the lower ends of the guide pipes 19 can buffer the impact force when the materials fall, so that the impact force of the materials to the mashing rollers 5 is reduced, the service life of the mashing rollers 5 is prolonged, when the guide pipes 19 are impacted by the materials, the guide pipes 19 can intermittently shake up and down, the knocking plates 22 are driven by the L-shaped plates 21 to shake up and down, the knocking plates 22 indirectly knock the upper ends of the circular screen 12, so that the rotating circular screen 12 can vibrate at the same time, the blocking materials at the inner tops can fall off from the meshes more easily, thereby improving the effect of the circular screen 12, the circular screen 12 can also enable the materials at the inner bottoms to separate more efficiently, when the air bag 22 is knocked down, the air bag 22 is blown down, the air bag 25 is blown down to the air bag 25, the air bag 30 is sucked up and sucked into the air bag 30, the air bag 30 is blown down by the air bag 25, and the air bag 30 is blown down by the air bag 30, and the air bag 30 is blown down by the air bag 25, and the air bag 26 is blown into the air bag 30, and the air bag 26, and the air bag is blown into the air bag, and the air bag. The air suction pipe 28 takes away part of heat on the mashing roller 5, so that heat dissipation is carried out on the mashing roller 5, and the service life of the mashing roller 5 is ensured.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art who is skilled in the art to which the present invention pertains should make equivalent substitutions or modifications according to the technical scheme and the inventive concept disclosed herein, and should be covered by the scope of the present invention.
