Detailed description of the invention
See Fig. 1 to Fig. 3, full casting welding mine crushing groove comprises middle plate 10, base plate 20, riser 30, riser 30 is symmetrical along the groove width direction of breaking tank, be parallel to each other two pieces of risers 30 of vertical setting, middle plate 10 and base plate 20 are horizontally fixed between two pieces of risers 30, middle plate 10 and base plate 20 are parallel to each other, base plate 20 is arranged on the below of middle plate 10, middle plate 10 comprises middle thick section 101 and plate parallel-segment 102 in being connected with middle thick section 101 head and the tail, the thickness of middle thick section 101 is greater than the thickness of middle plate parallel-segment 102, the lower surface of middle thick section 101 is for datum level is to downward-extension 10mm with the lower surface of middle plate parallel-segment 102, to form plate arcwall face in downward protrusion, be connected smoothly between the lower surface of middle plate arcwall face and middle plate parallel-segment 102, the base plate parallel-segment 202 that base plate 20 comprises central concave section 201 and is connected with central concave section 201 head and the tail, the thickness of central concave section 201 is less than the thickness of base plate parallel-segment 202, the upper surface of central concave section 201 is for datum level is to downward-extension 10mm with the upper surface of base plate parallel-segment 202, to form the base plate arcwall face to lower recess, be connected smoothly between the upper surface of base plate arcwall face and base plate parallel-segment 202, the middle thick section 101 of middle plate 10 is just right up and down in vertical direction with the central concave section 201 of base plate 20, the length of central concave section 201 is not less than the length of middle thick section 101, such as, the length of central concave section 201 is greater than the length of middle thick section 101.
Above-mentioned full casting welding mine crushing groove operationally, the broken shaft group of disintegrating machine is across being overlapped on two pieces of risers 30, broken shaft group comprises broken cutter tooth, therefrom plate parallel-segment 102 carries the bulk coal cinder of coming to be knocked fragmentation through the below of broken cutter tooth, so the position of middle plate 10 just right below broken cutter tooth bears the maximum position of impact, the namely middle thick section 101 of middle plate 10, in the ratio done by thickness herein, the thickness of plate parallel-segment 102 is thicker, exactly in order to increase its intensity.
On the upper surface of middle plate 10, to walk between middle plate 10 and base plate 20 and carry the flight chain of coal cinder, pass through smoothly from the distance between middle thick section 101 and base plate 20 to make flight chain, base plate 20 also corresponding making becomes the shape with central concave section 201, when the length of middle thick section 101 is equal with the length of central concave section 201, flight chain can be normal through, but flight chain can rub the central concave section 201 of base plate 20 be connected with base plate parallel-segment 202 transition flex point place, in the course of time, the concentrated wear of base plate 20 can be caused again serious, in order to reduce the wearing and tearing of flight chain to base plate 20 flex point place, so the length of the central concave section 201 of base plate 20 to be accomplished the length of the middle thick section 101 being greater than middle plate 10.
See Fig. 4, further, due to the upper surface of flight chain and chain direct friction base plate 20, especially the vertical chain link 70 of chain is little with the contact area of base plate 20, to the upper surface serious wear of base plate 20, often to wear and tear in the upper surface of base plate 20 elongated channels, base plate 20 is made to there will be crackle at this groove place, crack, the intensity of base plate 20 is obviously reduced, the lower surface of base plate 20 arranges bottom surface reinforcement 203 along the length direction of base plate 20 and width, bottom surface reinforcement 203 is alongst just to the position that the vertical chain link for flight chain on the upper surface of base plate 20 is walked, to strengthen the intensity of base plate 20 herein.
Further, form grid groove 204 between bottom surface reinforcement 203 and bottom surface reinforcement 203, the groove depth of grid groove 204 is 1/8 ~ 1/5 of the thickness of base plate 20.The design of grid groove 204 not only increases the frictional force on base plate 20 and ground, and reduces the weight of base plate 20 and whole breaking tank.
Wherein, because this breaking tank adopts casting manufacture, conveniently Foundry Production, the drift angle of grid groove 204 is fillet, and fillet can also reduce the stress of edge, the formation in Crack prevention crack.
Further, full casting welding mine crushing groove also comprises drawing and moves plate 40, draws to move plate 40 and be fixedly installed on the sidewall of riser 30, and drawing and moving plate 40 is two, is symmetricly set on the position that two pieces of risers 30 are symmetrical respectively, offers connecting hole drawing to move on plate 40.When breaking tank needs mobile, the cylinder head of the hydraulic jack in disintegrating machine is connected to this draw move plate 40 connecting hole on, namely whole breaking tank can be driven to move by the flexible of hydraulic jack.
Further, full casting welding mine crushing groove also comprise be fixedly installed on riser 30 top on along 50, on along 50 width be greater than the width of riser 30, and on direction between along 50 to two pieces of risers 30 extend.On can retrain flight chain along 50 and the coal cinder that is transferred moves along in the space between 50 and middle plate 10 upper.
Further, full casting welding mine crushing groove also comprises two for connecting the Connection Block 60 of external equipment, and Connection Block 60 is separately positioned on two ends of riser 30, for forward and backward connection elevating conveyor.
Full casting welding mine crushing groove adopts composite abrasion resistance material to make, and the chemical analysis of described composite abrasion resistance material is C0.3%, Mn1%, Si0.85%, Cr1.32%, Ni0.53%, Mo0.3%, V0.45%, Cu0.8%, and all the other are Fe.
Manufacture an evaporative pattern integral casting method for above-mentioned full casting welding mine crushing groove, comprise the following steps:
Use polyurethane vinyl particle prefoam manufacture entirely to cast welding mine crushing groove mould, foam density is 16g/cm3;
Mould swabbing obtains casting mold: stir as first pass, the sprayed coating of second time using the sub-aluminium spar powder of 90% mass ratio and the mixed mixture of milky white adhesive of 10% mass ratio and water according to the ratio of 3:7, when first pass coating is brushed to described full casting welding mine crushing groove mould, along the length direction sprayed coating of full casting welding mine crushing groove mould, coating thickness is 0.7mm ~ 1.2mm, then be placed in the drying chamber baking 5h of 50 DEG C, then repeat above-mentioned spraying method and spray second time; The composite coating mixed in the ratio of 1:10 by glue plant powder and water through etherificate process is as the sprayed coating of the 3rd time, the 4th time, 3rd time, the 4th time spraying method is same as first pass spraying method, the gross thickness of the coating after spraying is 4mm ~ 5mm, after spraying to casting mold.
