Abstract
The utility model relates to a roll structure in a double-toothed-roll screening crusher. A breaker roll in the double-toothed-roll screening crusher comprises a main shaft, wherein a plurality of toothholders are sleeved on the main shaft, and each toothholder is radially provided with tooth caps in identical number. The projections of the corresponding tooth caps of all toothholders on a circle which is vertical to the main shaft rotate in one direction, and the projections of the corresponding tooth caps on two adjacent toothholders on the circle form an angle of 18 to 25 DEG. According to the breaker roll, the tooth caps are arranged in a staggered way in different angles of 18 to 25 DEG according to the feeding granularity and the productivity, so that the corresponding tooth caps on different toothholders form a spiral structure along the main shaft, not only can the engagement performance of the double-toothed-roll screening crusher be improved, but also the productivity can be greatly improved, and the performance and the efficacy of the double-toothed-roll screening crusher can be effectively improved.
Description
Technical field
The utility model relates to a kind of structure of disintegrating machine middle roller.

Disclose a kind of toothing of double teeth roller screening crusher in the prior art, each crushing teeth on each roller of this disintegrating machine is by axially being arranged in order, the adjacent crushing teeth alternate 15 degree layout that staggers that makes progress in the same footpath of main shaft.Its discaling roll is stung incessantly the large scale material, can cause the putty phenomenon, and its breaking capacity is less, is not suitable for the action need of having relatively high expectations to breaking capacity in large-scale colliery etc.
Summary of the invention
It is strong that the utility model aims to provide a kind of broken dynamics, breaker roll in the double teeth roller screening formula disintegrating machine of pan feeding great efforts.
Breaker roll in the double teeth roller screening formula disintegrating machine described in the utility model, comprise main shaft, on the main shaft socket several toothholders, the tooth cap of equal number radially has been installed on each toothholder, respective teeth cap on all toothholders rotates to a direction perpendicular to the projection on the circle of main shaft successively same, and the projection of the respective teeth cap on the adjacent toothholder on this circle forms 18-25 degree angle.
Preferably, four tooth caps towards radial direction have been installed equably on each toothholder, the top of these four tooth caps is positioned on the same circle, and the center of circle of this circle is positioned on the axis of main shaft.
More preferably, described tooth cap comprises crown and the body that is connected with toothholder, and its mesostyle is hammer shape, and the crown bottom links to each other with body and forms acute angle.
Further preferably, crown is by tangent and continuous successively top straight line, four arcs and tail rectilinear(-al), spacing between top straight line, tail straight line and the tie point that body links to each other is 60mm, the four arcs radius is followed successively by 60mm, 22.5 mm, 60mm and 10mm, the spacing between second section circular arc and the body is 52.5mm.
Perhaps preferably, described tooth cap is to be removably mounted on the toothholder.
More preferably, described tooth cap is removably mounted on the toothholder by bolt.
The dislocation that the utility model is selected the tooth cap to be carried out different angles such as 18-25 ° according to material size and production capacity is arranged, make the respective teeth shade main shaft on the different toothholders form helical structure, both can improve " engaging-in " performance of screening formula disintegrating machine, can increase production capacity significantly again, improve performance and the usefulness of double teeth roller screening formula disintegrating machine effectively.

The specific embodiment
Embodiment one.
Breaker roll in the double teeth roller screening formula disintegrating machine described in the utility model, comprise main shaft 1, the socket of main shaft 1 equal intervals ground 12 toothholders 2, wherein be provided with 4 teeth that extend radially equably on each toothholder 2, on the tooth socket tooth cap 3, they are respectively, down, a left side, right tooth cap 3, last tooth cap 3 on each toothholder 2 is around 1 one-tenth helical arrangement of main shaft of breaker roll, lower tooth cap 3 on each toothholder 2 is around 1 one-tenth helical arrangement of main shaft of breaker roll, left tooth cap 3 on each toothholder 2 is around 1 one-tenth helical arrangement of main shaft of breaker roll, and the right tooth cap 3 on each toothholder 2 is around 1 one-tenth helical arrangement of main shaft of breaker roll.
Particularly, the respective teeth cap 3 on all toothholders 2 rotates to a direction perpendicular to the projection on the circle of main shaft 1 successively same, and the projection of the respective teeth cap 3 on the adjacent toothholder 2 on this circle forms 18-25 degree angle.
All tooth caps 3 are removably mounted on the toothholder 2 by bolt 6.When needs are replaced or keep in repair, can dismantle simply, and then install simply.
Described tooth cap 3 comprises crown 4 and the body 5 that links to each other with toothholder 2, and its mesostyle 4 is hammer shape, and crown 4 bottoms link to each other with body 5 and form acute angle.Its mesostyle 4 is by tangent and continuous successively top straight line, four arcs and tail rectilinear(-al), spacing between top straight line, tail straight line and the tie point that body 5 links to each other is 60mm, the four arcs radius is followed successively by 60mm, 22.5 mm, 60mm and 10mm, the spacing between second section circular arc and the body 5 is 52.5mm.
Embodiment two.
Have two in the present embodiment as breaker roll in the embodiment one described double teeth roller screening formula disintegrating machine, during installation, two breaker rolls are to arrange abreast.And in two projections of breaker roll on same vertical plane, first toothholder 2 is arranged in the gap of the right second and third breaker roll of breaker roll in the breaker roll of the left side, the gap of third and fourth breaker roll of breaker roll on the right of second toothholder 2 is arranged in the breaker roll of the left side, the toothholder 2 of back is so method setting successively.
Wherein in the breaker roll on the left side, tooth cap 3 is right-hand screws; In the breaker roll on the right, tooth cap 3 is left-hand screws.
After machine started, because the toothholder 2 of two breaker rolls is alternate settings, making did not have the dead angle in the shattering process, and all materials can both obtain the active force of tooth cap 3 in dropping process.And the spiral of tooth cap 3 is relative, and the suppressing action time of the tooth cap 3 that is subjected in dropping process of the material at the diverse location place staggers like this, makes the material can be at one time to the inner extruding of breaker roll, thereby improves broken efficient.Marker size just can be controlled in the gap of two relative tooth caps 3 in addition.Need control between 150-300mm as the raw meal particle size of last discharge, only the gap of two relative tooth caps 3 need be adjusted into 150-300mm and get final product.
