Detailed Description

The technical solution provided by the invention is explained in more detail below with reference to fig. 1-3.

As shown in fig. 1-3, an embodiment of the present invention provides a durable dual-shaft shredder, which includes a shredding roller shaft 1, wherein the shredding roller shaft 1 includes a rotating shaft 2 and a plurality of blades, the blades are disposed on the rotating shaft 2, the blades are detachably disposed between the rotating shaft 2, and the blades are disposed in a manner of gradually reducing in size from the middle of the rotating shaft 2 to the two sides of the rotating shaft 2. Through setting the blade to different sizes, the blade that is located 2 middle parts of pivot can be bigger, the size of blade reduces the setting gradually in the direction from 2 middle parts of pivot to 2 both sides of pivot, because equipment is at the in-process of shredding the material, mainly the blade at 2 middle parts of pivot is shredding, so the blade wearing and tearing that are located 2 middle parts of pivot can be faster, the blade receives wearing and tearing back and will diminish, blade after diminishing can dismantle and get off and install 2 positions in the pivot of this blade size of adaptation, make the blade after receiving wearing and tearing to diminish can continue to use, the durability of blade has been improved.

Durable biax shredder includes casing 3 and a plurality of stationary knife, and on the stationary knife set up casing 3, for dismantling the setting between stationary knife and the casing 3, the size of stationary knife dwindles the setting gradually in the direction that the stationary knife that is located the middle part is to the stationary knife that is located both sides. Through being provided with the stationary knife, pivot 2 drives the blade and rotates and cooperate the stationary knife again for the shredding effect of material is better. Through setting the stationary knife to different sizes, the stationary knife that is located the middle part can be bigger, the size of stationary knife reduces the setting gradually in the direction that the stationary knife that is located both sides from the stationary knife that is located the middle part is to the stationary knife that is located both sides, because equipment is at the in-process of shredding the material, the material mainly concentrates on middle part shredding, so the stationary knife that is located the middle part can wear and tear sooner than the stationary knife of both sides, will diminish after the stationary knife receives wearing and tearing, the stationary knife after diminishing can be dismantled and get off and install the position that is fit for this stationary knife size, make the stationary knife after receiving wearing and tearing to diminish to continue to use, the durability of stationary knife has been improved.

Be provided with a plurality of annular blade holder 4 on the shredding roller 1, the blade setting is on annular blade holder 4, and annular blade holder 4 interval distribution is in pivot 2, and annular blade holder 4 reduces the setting from the direction of middle part to both sides interval gradually, and the stationary knife stretches into in the interval that corresponds. By adopting the structure, the shredding effect of the equipment on the materials is improved under the matching arrangement of the blades and the fixed knives.

The shredding roll shaft 1 is provided with two, namely a first shredding roll shaft 5 and a second shredding roll shaft 6, blades of the first shredding roll shaft 5 extend into the interval of the annular cutter holder 4 of the second shredding roll shaft 6, and blades of the second shredding roll shaft 6 extend into the interval of the annular cutter holder 4 of the first shredding roll shaft 5. Adopt above-mentioned structure, set up down in the cooperation of first shredding roller 5 and second shredding roller 6, promoted the shredding effect of equipment to the material.

Be provided with feed inlet 7 on casing 3, shredding roller 1 is located the inside of casing 3, and feed inlet 7 is located directly over between first shredding roller 5 and the second shredding roller 6. Through setting up feed inlet 7 directly over between first shredding roller 5 and second shredding roller 6, the material that gets into from feed inlet 7 can mostly reach the shredding position between first shredding roller 5 and second shredding roller 6 to improve equipment is to the shredding effect of material.

Be provided with discharge gate 8 on casing 3, shredding roller 1 is located the inside of casing 3, and discharge gate 8 is located first shredding roller 5 and second shredding roller 6 between under. Because the material after being shredded mostly is from the whereabouts between first shredding roller 5 and the second shredding roller 6, after the tire is shredded through first shredding roller 5 and second shredding roller 6, the tire can follow and fall to discharge gate 8 department between first shredding roller 5 and the second shredding roller 6, more is favorable to being discharged from discharge gate 8 by the material after being shredded, has accelerated ejection of compact time, prevents that the condition of jam from taking place.

First roller 5 and the second of tearing up tears are torn up roller 6 and are located same high department, adopt above-mentioned structure, more are favorable to tearing up the material and are favorable to the material whereabouts after tearing up to discharge.

Be provided with a plurality of blade holder 9 on the 3 inner walls of casing, the top and the below of blade holder 9 all are provided with stationary knife installation position 10, and the stationary knife sets up on stationary knife installation position 10, and the stationary knife sets up for the slope, and the cutting edge orientation of stationary knife tears the setting of roller 1. Adopt above-mentioned structure, promoted the shredding effect of stationary knife to the material.

The blade holders 9 are disposed at the side of the first shredder roller 5 and the side of the second shredder roller 6, respectively. Adopt above-mentioned structure, promoted the shredding effect of stationary knife to the material.

Each annular cutter holder 4 is provided with a plurality of blade mounting positions 11, blades are arranged on the blade mounting positions 11, and the blade mounting positions 11 are distributed in an array mode around the central axis of the annular cutter holder 4. By adopting the structure, the distribution of the blades is more uniform, and the shredding effect of the equipment on the materials is better.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
