Claims

[Claims for Utility Model Registration] (1) A first device having a frame means, a stand means attached to the frame means and having a shearing space, and a rotating shearer rotatably attached to cross the shearing space of the stand means. a first hopper having a chamber attached to the platform means and communicating with the shearing space of the platform means below, and a rotary cutter rotatably fitted into the chipping chamber and the chipping chamber; a second chipping means attached to the frame means below the first chipping means; and a second chipping means fixed between the first chipping means and the second chipping means interconnecting the shearing space and the chipping chamber. a second hopper having a chamber for scraping plastic; and a second hopper drivingly connected to a rotary cutter of the second chipping means and a rotary shear of the first chipping means for passing the scrap plastic through the cutter and the shears. A chipper comprising a drive means for rotating the chips so that they are chipped, a grating means located at the bottom or outlet end of the chipping chamber of the second chipping means, and a receiver located below the grating means. (2) The rotary shear of the first chipping means has a plurality of sets of hook-shaped shear members oriented circumferentially and longitudinally about the shaft. Chitzpah. 3. The chipper of claim 2, wherein each set of shear members of the rotary shear comprises three shear members that are similarly bent and aligned on the shaft 120 degrees apart in the circumferential direction. (4) The chipper according to claim 2, wherein the front end of the shearing member of the rotary shearer has a sharp tip. (5) The chipper according to claim 3, wherein the sets of shearing members are distributed longitudinally at the same distance on the shaft and are sequentially retracted by 15 degrees in the circumferential direction. 6. The chipper according to claim 1, wherein the plurality of pawls fixedly attached to the base means extend perpendicularly to the shaft into the spacing between adjacent sets of shearing members of the rotary shearer. 7. A chipper according to claim 1, wherein the rotary cutter of the second chipping means has a series of hubs correspondingly mounted on its shaft. (8) Each hub of the rotary cutter has 12
Chipper according to claim 7, characterized in that it has three inclined flat sections on which are fixedly mounted three blades having sharp leading edges located at 0 degree intervals. (9) The rotational speed of the rotary shear of the first chipping means is set to 1/30 of the rotational speed of the rotary cutter of the second chipping means by means of a gearbox mechanism between the drive means and the first chipping means. The chipper according to claim 1, wherein the chipper is decelerated to .
