Detailed description of the invention
In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
A kind of mill thorax device of detonation machine as shown in Figure 1-2 for the present invention relates to, comprises mill thorax body 1 and bit mechanism.
Mill thorax body 1 is connected with between coal bunker 5 and discharging chamber (band rotary blade 6), and mill thorax body 1 is in hollow cylinder tubular, and it has feed end 11 and discharge end (not shown), and the madial wall milling of this mill thorax body 1 is sawtooth coil structures 12.
Described bit mechanism is arranged in mill thorax body 1, and it comprises corase grind bit mechanism 3 and fine grinding bit mechanism 4, and this corase grind bit mechanism 3 and fine grinding bit mechanism 4 all axle are located on same rotating shaft 2.Described corase grind bit mechanism 3 is arranged near the feed end 11 of described mill thorax body 1, this corase grind bit mechanism 3 comprises tool rest 31 and around the equally distributed some groups of sharpening portions 32 of this tool rest 31, often organize sharpening portion 32 and comprise the head 322 being fixed on the arm 321 on described tool rest and being connected with at this arm 321 free end in one end, the arm 321 in the concrete sharpening portion 32 that often organizes establishes one, forms " T " font structure with the corresponding head 322 be connected with.As shown in Figure 1, the axial direction of described head 322 in strip and along mill thorax body 1 is extended, head 322 is being isosceles trapezoid shape along grinding thorax body 1 cross section in the radial direction, and a side of this isosceles trapezoidal structure upper base arranges (leaving the gap of 3-5mm between the two) near the madial wall of mill thorax body 1.
Described fine grinding bit mechanism 4 is arranged away from the feed end 11 of described mill thorax body 1, this fine grinding bit mechanism 4 includes tool rest 41 and around the equally distributed some groups of sharpening portions 42 of this tool rest 41, the group number in the sharpening portion 32 of described corase grind bit mechanism 3 is less than the group number in the sharpening portion 42 of fine grinding bit mechanism 4, the group number in the sharpening portion 32 of further corase grind bit mechanism 3 is 1/2nd of the group number in the sharpening portion 42 of fine grinding bit mechanism 4, a concrete embodiment is that 32 groups, the sharpening portion number of corase grind bit mechanism 3 is provided with 3 groups, and 42 groups, the sharpening portion number of fine grinding bit mechanism 4 is provided with 6 groups.The head 422 that described sharpening portion 42 comprises arm 421 and is connected with at this arm 421 free end, the arm 422 preferably often organizing sharpening portion 42 is provided with two, forms isosceles triangular structure with the corresponding head 421 be connected with.The head 322 of the structure of described head 422 and set-up mode and described corase grind bit mechanism 3 in like manner, tires out no longer in detail here and states.
When the mill thorax device of detonation machine of the present invention grinds solid coal, solid coal is via coal bunker 5, send into from the feed end 11 of mill thorax body 1, first rough lapping is carried out through corase grind bit mechanism 3, importing fine grinding bit mechanism 4 of taking advantage of a situation afterwards carries out fine lapping, is finally blown out by the rotary blade 6 of mill thorax body 1 discharge end.Corase grind bit mechanism 3 and fine grinding bit mechanism 4 axle are located on same rotating shaft 2, and the group number in the sharpening portion 32 of this corase grind bit mechanism 3 is less than the group number in the sharpening portion 42 of this fine grinding bit mechanism 4, thus under the common rotary actuation of rotating shaft 2, the severity of grind of fine grinding bit mechanism 4 is higher than the severity of grind roughly grinding bit mechanism 4, and the often sharpening portion 42 of certain fine grinding bit mechanism 4 also by establishing the number of arm 422 to strengthen its severity of grind more; The cross section of the head 321,421 of this case corase grind bit mechanism 3 and fine grinding bit mechanism 4 adopts isosceles trapezoid shape design, corase grind bit mechanism 3 and fine grinding bit mechanism 4 rotating, more crucial is that the inclined design of waist portions makes to be formed to hold between this waist portions and mill thorax body 1 to expect space, in grinding, solid coal smooth and easyly can to enter in this appearance material space and to be divided by upper bottom portion and effectively grind, compared to existing technology, this case mill thorax device to the grinding of solid coal more effectively fully, grinding efficiency is also higher, substantially increases the overall performance of detonation machine thus.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present invention.
