Abstract
The utility model discloses a kind of coal mining machine roller cylinder bottom outer ring and loads inclined plate, including cylinder, it is characterized in that, the outside of the cylinder is equipped with several helical blades, one end of the helical blade is equipped with toothholder, tooth set and pick successively, the other end is equipped with cylinder circle, and the toothholder is fixed on the end of helical blade, and the pick is mounted on by tooth set on toothholder；The bottom of the cylinder circle and the angle of cylinder outer ledge are a, wherein, 0 45 ° of ＜ a ＜, the cylinder circle is fixed by the supporting rack being arranged in angle a.The utility model adds cylinder circle by the region between conventional tumble cylinder body bottom and adjacent blades, when so that the coal is flow to blade afterbody, have and raise upward hydrodynamic effect, the effect that coal stream is thrown into chute by rocking arm upper and lower is greatly improved, so as to improve Cutting Performance, reduces the vibrations of coal machine and spare parts consumption, extend the coalcutter service life, meanwhile reduce and lose coal rate, reduce the waste of resource.
Description
Technical field
The utility model is related to a kind of coal mining machine roller, specifically a kind of coal mining machine roller cylinder bottom outer ring loads inclined plate, belongs to
In the technical field of coal mine machinery.
Background technology
It mines, is exactly no matter valuable coal is revealed from underground or earth's surface separation and shipped off-site, coal mining technology
It or underground on the basis of the high mechanization reached at present, are just developed towards the remote control of production process, automation direction,
By improving design, type selecting, material, manufacturing process, the method for inspection and the maintenance of fully-mechanized mining equipment, its production capacity will be improved
And utilization rate of equipment and installations, it needs to use a kind of coalcutter during common coal mining, then due to technical problem, common coal mining
Machine abrasion is severe, and service life is short, not only affects production efficiency, also increases maintenance cost.In the big production of coal mine machineryization
Background under, effect of loading coal well become coal mining machine roller basic demand.The mechanism of conventional coal mining machine roller is as shown in Figure 1, adopt
With optimization helical blade lift angle, cutting can not be taken into account sometimes with loading effect, to ensure the Cutting Performance of roller, can only sacrifice dress
Effect is carried, the coal being scattered is not easily recycled, increases and lose coal rate, causes the significant wastage of the energy.
Invention content
It is loaded tiltedly in view of the above-mentioned problems of the prior art, the utility model provides a kind of coal mining machine roller cylinder bottom outer ring
Plate can effectively solve the problem that the cutting technical barrier undesirable with loading effect.
To achieve these goals, a kind of coal mining machine roller cylinder bottom outer ring that the utility model uses loads inclined plate, including
Cylinder, which is characterized in that the outside of the cylinder is equipped with several helical blades, and one end of the helical blade is equipped with tooth successively
Seat, tooth set and pick, the other end are equipped with cylinder circle, and the toothholder is fixed on the end of helical blade, and the pick is covered by tooth pacifies
On toothholder；The bottom of the cylinder circle and the angle of cylinder outer ledge are a, wherein, 0 45 ° of ＜ a ＜, the cylinder circle passes through
The supporting rack being arranged in angle a is fixed.
Preferably, support frame as described above may be used the gusset of tilting, and gusset is fixed on the outside of cylinder, gradient with
The angle of angle a matches.
Preferably, the cylinder circle is segmented flared structure.
Preferably, the cylinder circle is formed by stainless steel welded.
Preferably, the pick includes ratch and the tooth head for being set to ratch one end, and the tooth head is conical structure,
And the front end of tooth head is fixed with conical alloy head.
Compared with prior art, the utility model is increased by the region between conventional tumble cylinder body bottom and adjacent blades
If cylinder circle, when so that the coal is flow to blade afterbody, have and raise upward hydrodynamic effect, greatly improve coal stream by rocking arm upper and lower
The effect of chute is thrown into, so as to improve Cutting Performance, the vibrations of coal machine and spare parts consumption is reduced, extends the coalcutter service life,
Meanwhile reduce and lose coal rate, reduce the waste of resource.
