At present, produce the appliance shell and other waste or used plastics etc. in the block glue head and waste household appliances produced in plastic rubber product process, before recovery and reusing and recycling, need leading fragmentation, and hand breaking is wasted time and energy, efficiency is very low.More satisfactory mechanical crushing appliance is also not yet noticed.
Utility model content
In order to strengthen the recycling to waste or used plastics rubber, improve degree of fragmentation and the crushing efficiency of waste or used plastics rubber, alleviate labor strength, the utility model provides a kind of single-shaft shredder.
For achieving the above object, the technical scheme that the utility model adopts for its technical problem of solution is: single-shaft shredder comprises frame 15, casing 1, cutter shaft 12, push pedal 5, push pedal guide rail 6, hydraulic push rod 2, hydraulic jack 3, fixed head 7, feed hopper 4, discharge bucket 14; Be fixedly connected with by bolt 24 between frame 15 with casing 1, hydraulic jack 3 and motor 17 are installed below frame; Casing 1 is equipped with cutter shaft 12, have on the surface of cutter shaft 12 some parallel to each other and be parallel to the triangle teeth groove of the diameter of axle, weld moving knife seat 9 in triangle teeth groove, moving knife seat 9 bolt is connected and installed cutting blade 8; With the both sides box plate of cutter shaft 12 axial line degree in a vertical angle on pair of push plates guide rail 6 is fixedly housed, push pedal guide rail 6 is above provided with push pedal 5; Push pedal 5 connects the push rod termination of hydraulic push rod 2 by pin, and one piece of fixed head 7 slided for push pedal 5 is fixedly equipped with in the below of push pedal 5 between box side; Fixed head 7 is equipped with stationary knife seat two in the one end near cutter shaft 12, and stationary knife seat dual-purpose bolt connects ledger-plate two, and ledger-plate two offers triangle teeth groove; In the middle of casing 1, stationary knife seat one is fixedly housed, stationary knife seat one bolt connects ledger-plate one, and ledger-plate one offers triangle teeth groove; Casing 1 is built with screen cloth 13; Feed hopper 4 is equipped with in the top of casing 1, and discharge bucket 14 is equipped with in the below of casing 1.
The beneficial effects of the utility model are: strengthen the recycling to waste or used plastics rubber, be conducive to environmental protection, greatly reduce the labour intensity that hand breaking method is brought to workman simultaneously.

Detailed description of the invention
Accompanying drawing 1 to accompanying drawing 25 indicates the detailed description of the invention of the same embodiment of the utility model jointly.
, in conjunction with the course of work of single-shaft shredder detailed description of the invention of the present utility model to be described further below in conjunction with accompanying drawing.
Starter motor 17, cutter shaft 12 rotates; Primer fluid pressing system, makes the push rod termination of hydraulic push rod 2 drive push pedal 5 to against push pedal guide rail 6 and moves to hydraulic cylinder cylinder sleeve direction, open to make the charging aperture of feed hopper 4; Glue head or waste plastics is poured into from feed hopper 4; Operation hydraulic push rod 2, make push rod 2 promote push pedal 5 to move to cutter axis orientation, because between the rectangular plate in bottom of push pedal 5 and fixed head 7, gap is less, the material be introduced into into is just unlikely to hide leakage from gap, waste material, when being pushed to cutter shaft 12 direction, is just extruded and fragmentation; Broken material is discharged from discharge bucket 14 through screen cloth 13.
Cutting blade 6 of the present utility model is provided with four nose angles protruded in cambered surface forward, very sharp; Evenly install three in every bar triangle teeth groove of cutter shaft 12 cutting blade 8, cutting blade 8 offset angular often in adjacent two triangle teeth groove is installed.The broken great efforts of the utility model, crushing efficiency are high.
