Description
Technical field
The utility model relates to the Novel sieve plate being applicable to hammer mill, belongs to hammer mill technical field.
Background technology
Hammer mill mainly completes broken material operation by impact energy.During hammer mill work, High Rotation Speed made by driven by motor rotor, material enters in disintegrating machine chamber uniformly, the pivotal tup of high speed impacts, shearing splitting material causes material and is broken, simultaneously, the Action of Gravity Field of material self makes material rush at support body Internal baffle, grating from the tup of High Rotation Speed, and broken material granularity is finally by outside sieve plate discharge machine.But the easy detention of the material slightly larger than screen size is on sieve plate, need tup strike repeatedly and grinding, sometimes broken material grain is just just stuck on sieve plate then can not smooth and easy discharging, secondly, due to the gap between tup and casing, sieve plate end positions is hit relatively smaller, material grain easily accumulates on this, and the two ends, aperture of existing sieve plate are the same with centre, easily there is detention in the material grain at two ends, screening effect is poor.
Summary of the invention
The purpose of this utility model is to provide the Novel sieve plate being applicable to hammer mill, can overcome the deficiencies in the prior art, makes the smooth and easy discharging of material grain, improves screening effect.
The purpose of this utility model is achieved through the following technical solutions: the Novel sieve plate being applicable to hammer mill, comprise sieve plate main body, the cross section of sieve plate main body is curved, sieve plate main body is provided with the some bar shaped screen holes be evenly distributed in the middle part of sieve plate main body and the trapezoidal sieve being distributed in bar shaped screen hole two ends, the cross section of bar shaped screen hole and trapezoidal sieve is the large bell mouth shape in little outside, inner side, the length on the narrow limit of trapezoidal sieve is D1, the length on the narrow limit of bar shaped screen hole is D2, wherein, D1 >=D2.
The length of described trapezoidal sieve is no more than the half of bar shaped screen hole length.
Spacing between described trapezoidal sieve and bar shaped screen hole, between adjacent bar sieve aperture is 50mm
-100mm.
The radian of described sieve plate main body is 20 °
-35 °.
On described trapezoidal sieve, the length of broadside is W1, and the spacing between adjacent bar sieve aperture is M, W1≤D2+M.
The beneficial effects of the utility model are: by changing the arrangement form of sieve aperture and the shape of sieve aperture, make pellet discharging smooth and easy, can not cause the detention of material grain, improve screening effect, and have structure feature simple, easy to use.

Fig. 4 be in Fig. 1 B-B to schematic diagram;
Fig. 5 is the second structural representation of the present utility model.
Wherein, 1-sieve plate main body, 2-bar shaped screen hole, 3-trapezoidal sieve.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As Fig. 1, Fig. 2, be applicable to the Novel sieve plate of hammer mill, comprise sieve plate main body 1, the cross section of sieve plate main body 1 is curved, sieve plate main body 1 is provided with the some bar shaped screen holes 2 be evenly distributed in the middle part of sieve plate main body 1 and the trapezoidal sieve 3 being distributed in bar shaped screen hole 2 two ends, as Fig. 3, Fig. 4, the cross section of bar shaped screen hole 2 and trapezoidal sieve 3 is the large bell mouth shape in little outside, inner side, be convenient to pellet discharging here, under the impact of tup, the easier discharge sieve plate of pellet pulverized, the length on the narrow limit of trapezoidal sieve 3 is D1, the length on the narrow limit of bar shaped screen hole 2 is D2, wherein, D1 >=D2.
The length of described trapezoidal sieve 3 is no more than the half of bar shaped screen hole 2 length.
Spacing between described trapezoidal sieve 3 and bar shaped screen hole 2, between adjacent bar sieve aperture 2 is 50mm
-100mm.
The radian of described sieve plate main body 1 is 20 °
-35 °.
On described trapezoidal sieve 3, the length of broadside is W1, and the spacing between adjacent bar sieve aperture 2 is M, W1≤D2+M, and the aperture of such discharging aperture, sieve plate 1 two ends and middle discharging is more or less the same, and manufacture and also facilitate, the pellet that ensure that out is comparatively even.
As Fig. 5, another kind of structural representation of the present utility model, sieve plate main body 1 is longer due to length, is provided with the equally distributed bar shaped screen hole 2 of two rows in the middle part of it, and high order end and the low order end of this two rows bar shaped screen hole 2 are provided with trapezoidal sieve 3.
