Abstract

The utility model relates to an improved structure of a smashing machine, wherein the improved structure of the smashing machine is labor-saving in shearing, simple and convenient to maintain and rapid in cutter replacement. The improved structure of the smashing machine is mainly characterized in that a smashing cutter set is disposed in a body, a hollow tubular rotary shaft of the smashing cutter is provided with a plurality of through grooves which are arrayed on the rotary shaft in a rifling spiral form, and a fixing seat is arranged in the rear of each through groove and allows a diamond movable blade to abut against. The bottom end of each diamond movable blade is sleeved into the corresponding through groove, and each diamond movable blade is provided with a through hole and penetratingly arranged on and in thread joint with a thread hole of the corresponding fixing seat through a thread joint element. The axial maximum width of each through groove is smaller than the diamond diagonal width of each movable blade to enable the diamond movable blade to be sleeved into the through grooves and directly positioned by the through grooves. Further, since the diamond movable blades are arrayed on the rotary shaft in the rifling spiral form, the improved structure of the smashing machine is labor-saving in shearing.

The specific embodiment

Below, now with regard to structure, characteristic and the use effect thereof of the utility model, cooperate graphic and preferred embodiment detailed description as back:

See also Fig. 1～shown in Figure 5, wherein, the utility model mainly is that a material bin 11 is set on a body 1; And both sides are provided with the fixed cutting tool 12 that is the dentation incisxal edge in the body 1, are the relative shear position with fixed cutting tool 12 in this body 1 and then are provided with crushing knife tool group 2, and this crushing knife tool group 2 is sheathed axles 22 in the rotating shaft 21 with a hollow tubular; The two ends of this axle 22 and rotating shaft 21 are established fixed through the weldering of a stator 23, this axle 22 can supply the drive motor transmission, and are provided with a plurality of dead slots 24 thoroughly in this rotating shaft 21; These a plurality of dead slots 24 are the setting of rifling helical arrangement respectively in rotating shaft 21; And should pass through dead slot 24 holder 25 was set in the relative rear of rotating shaft 21 rotation directions, and established a screw 251 on the holder 25, the rear of this holder 25 then is provided with reinforcing block 26; And this holder 25 can supply a rhombus movable blades 27 against; And the apparent size of this holder 25 is less than the apparent size of rhombus movable blades 27, and the bottom of this rhombus movable blades 27 then is sheathed in the dead slot 24, and an open-work 271 is set on this rhombus movable blades 27; And wear and spiral shell is tied the screw 251 in holder 25 through spiral shell knot element 28; And the axial Breadth Maximum of dead slot 24 is less than the cornerwise width of movable blades 27 rhombuses thoroughly, and when making rhombus movable blades 27 be sheathed on dead slot 24, the open-work 271 of this rhombus movable blades 27 can be positioned at the upper limb of dead slot 24; And can not hinder spiral shell to tie wearing of element 28; And should pass through on the dead slot 24 and axially be the thickness that vertical Breadth Maximum equals or be slightly larger than rhombus movable blades 27, rhombus movable blades 27 can accurately be sheathed in the dead slot 24, not rock and can not produce.

In this way, rhombus movable blades 27 is inserted in the dead slot 24, again spiral shell is tied open-work 271 and the spiral shell that element 28 wears rhombus movable blades 27 and tie screw 251 in holder 25; Can accomplish the group of single rhombus movable blades 27 establishes; Axial Breadth Maximum through passing through dead slot 24 makes when rhombus movable blades 27 is inserted in dead slot 24 less than the cornerwise width of movable blades 27 rhombuses, can directly receive the spacing of dead slot 24 axial edge and locatees; The operator need not to adjust rhombus movable blades 27 in the position of passing through on the dead slot 24 again; Only need that spiral shell is tied element 28 locks and establish, can locate rhombus movable blades 27, letter is changed or the operation of maintenance rhombus movable blades 27 to reach.

And when rhombus movable blades 27 is sheared with the fixed cutting tool that is the dentation incisxal edge 12 each other; The support of the reinforcing block 26 that is provided with through holder 25 and rear thereof; And make rhombus movable blades 27 be able to bear bigger stressed; And can reduce the damage of breaking of rhombus movable blades 27, to reduce the expenditure of cost.

Moreover; Be the setting of rifling helical arrangement because of passing through in dead slot 24 rotating shafts 21; Make sheathed rhombus movable blades 27 on it in rotating shaft 21, also be the setting of rifling helical arrangement, the shearing that makes every single rhombus movable blades 27 and fixed cutting tool 12 appear respectively and stagger, but not whole row's rhombus movable blades 27 is done shear action simultaneously with fixed cutting tool 12; And can reach the labour-saving cut mode, to reduce the output of power.

So, when 27 damages of rhombus movable blades or sharpness reduction, can only change with regard to single rhombus movable blades 27; And need not this cutter shaft by pulling down in the cell body, then with each cutter by separating on the main shaft, and change whole group cutter; With the expenditure of the minimizing cost of charp tool, and, take out rhombus movable blades 27 as long as spiral shell is tied element 28 to be unscrewed; Again that another is new rhombus movable blades 27 is inserted in the dead slot 24 again, and locking screw knot element 28 can reach the replacing of rhombus movable blades 27; So structure can reach laborsaving shearing, easy maintenance and change cutter fast, and the pulverizer structure-improved of escapable cost expenditure.

In addition, see also shown in Figure 6ly, it be the preferred embodiment of the utility model, wherein, in this fixed cutting tool 12, can be provided with the crushing knife tool group 2 more than two or two, with the crush efficiency of increase pulverizer.

Above-mentioned the utility model only illustrates with most preferred embodiment, to being familiar with the personnel of this skill, change enforcement when carrying out each, but this changes enforcement, all should be included in the spirit and category of the utility model.

In sum, the utility model then is sheathed in the dead slot through the bottom of rhombus movable blades, on this rhombus movable blades an open-work is set; And wear and spiral shell is tied the screw in holder through spiral shell knot element, and the axial Breadth Maximum that passes through dead slot makes when the rhombus movable blades is inserted in dead slot less than the cornerwise width of movable blades rhombus; Can directly receive the location of dead slot, and because of each rhombus movable blades is the setting of rifling helical arrangement in rotating shaft, and can reach laborsaving shearing; No matter it is the change of structure and the enhancement of effect; Unquestionable all, and the utility model is not shown in publication, also unexposed use before application; Meet the patent application requirement in fact, proposed patent application in accordance with the law.
