Abstract
The utility model discloses a spindle type impact crusher, the material entrance of which can center to a flexible charging hopper. Two flexible push-pull plates are arranged under the bottom plate of the charging hopper. The push-pull rods which push the push-pull plates can be one or two silk pole (s) or one or two hydraulic pole (s). The notches of the left and the right push-pull plates can be straight lines which present a certain angle, or can be arc shapes. If the straight lines present a right angle, the notches combined by the left and the right push-pull plates can be a square, no matter how the push-pull plates stretch, the notches can always keep the square, as long as the distances stretched by the push-pull plates are the same, the center of the square can be remained; therefore the material flow can be ensured to center and drop in the center of an axisymmetric body, and eccentric weight cannot be engendered due to the un-centering of the material flow. One silk pole can be used for pushing and pull the left and the right push-pull plates at the same time, and two silk poles or hydraulic poles can be used for realizing the left-right movement of the left and the right push-pull plates. The utility model has the advantages that the material flows can all be centered to the center of the axisymmetric body according to the different material amounts, no eccentric weight engenders due to the un-centering of the material flow, the service lives of the machine and the bearing can be prolonged, and the structure is simple.
Description
Affiliated technical field
The utility model relates to a kind of vertical shaft type impact crusher material bin, and particularly its feeding mouth can centering stretch.
Background technology
At present, vertical shaft type impact crusher material bin, material enter the feeding mouth of revolving body, have plenty of fixed size, can not regulate size, the design that has monolateral retractor device, can change the feeding that enters revolving body, but because of being monolateral flexible, when its feeding mouth dwindles, its material flow is not over against the revolving body center, and revolving body is rotation at a high speed, and is very responsive to eccentric weight, eccentric weight makes revolving body produce eccentric force, make body vibration, bearing is subjected to alternate stress, the lost of life.
Summary of the invention
In order to overcome the deficiency of existing monolateral retractor device material bin, the utility model provides a kind of feeding mouth centering material bin that stretches, not only can be according to working condition requirement, adjusting center blanking how much, and under different feeding operating modes, can both, materials flow not produce eccentric weight with material flow over against the revolving body center because of misaligning.
The technical scheme that its technical problem that solves the utility model adopts is: two telescopic draw back plates of installation below the material bin base plate.The pull bar that promotes draw back plate can be one or two screw mandrel, hydraulic stem.The breach of left and right sides draw back plate is angled straight line, also arc.If rectangular straight line, the breach that left and right sides draw back plate is combined into will be a square, and, no matter left and right sides draw back plate is stretched or is contracted, and its breach remains square always, as long as flexible distance is identical about the draw back plate of the left and right sides, its foursquare center will remain unchanged, like this, just can guarantee that material flow centering falls into the revolving body center, not produce eccentric weight because of materials flow misaligns.The breach of other shape also can guarantee materials flow centering.But symmetry is poor slightly.Can also can realize left and right sides draw back plate side-to-side movement with rhizoid bar push-and-pull simultaneously left and right sides draw back plate with two rhizoid bars or hydraulic stem.
The beneficial effects of the utility model are, the feeding mouth centering material bin that stretches can be according to different feedings, all with material flow over against the revolving body center, do not produce eccentric weight because of materials flow misaligns, prolong body, bearing life, simple in structure.
