Abstract

The utility model relates to a cone crusher, composed of a frame, a cone crushing chamber arranged in the frame and a drive pulley. The utility model is characterized in that the upper end of a moving cone is hung in a central bearing sleeve of the frame beam through a minor shaft and a bearing; the lower end of the moving cone is plugged in the eccentric crankshaft section of a transmission shaft through bearings. When the transmission shaft is rotating, the moving cone does conic surface screw pendulum movement around the center line of the transmission shaft, taking the fixed point of the shaft center of the minor shaft as the center. Accordingly, the clearance variation between the moving cone and a conical curve surface is realized and the goal of crushing material is achieved. The utility model has novel structure, and the crushing efficiency is raised by 5-10 percents.

Description

Gyratory crusher

The utility model relates to disintegrating machine, especially a kind of gyratory crusher.

Cone crusher belongs to the extrusion type disintegrating machine, has characteristics such as the few and operating cost of metal consumption is lower, so the employing gyratory crusher carries out the more of material pulverizing.The transmission system that the various gyratory crushers of domestic production at present adopt mostly be by motor through V belt wheel drive bevel gear pair and excentric sleeve, thereby drive mode, mantle and watt supporting of employing bowl-type of awl main axis rotation.Make the structure of existing gyratory crusher complicated thus, body is huge, and cost is higher, thereby has influenced selecting for use of equipment.

The purpose of this utility model is the deficiency that exists on the above-mentioned gyratory crusher structure, provide a kind of simple in structure, body is little and the gyratory crusher that is easy to make.

Gyratory crusher of the present utility model comprises: lower framework, middle part frame, upper stand, constitute crusher chamber by the mantle liner plate that is arranged on the fixedly liner plate in the upper stand and be arranged on the mantle body, it is characterized in that: upper stand is provided with a cross beam frame for the lifting of mantle body, minor axis is equipped with in the upper end of mantle body, and hangs in cross beam frame central shaft bearing sleeve by bearing; The lower end of mantle body is plugged on the eccentric crankshaft section of power transmission shaft by bearing.

The operation principle of gyratory crusher of the present utility model is: rely on from the heavy material cross beam frame charging aperture from upper stand to enter by mantle liner plate and the fixing crusher chamber that constitutes of liner plate, the mantle body that is arranged on the power transmission shaft rotates under the driving of belt wheel.Because the mantle body is mounted on the eccentric crankshaft section of power transmission shaft, so during the power transmission shaft rotation, the mantle body is to be the center with fixing point 0, centers on the center transmission shaft line and does conical surface swing campaign.Because the mantle body rotatablely moves as off-centre along the cone-shaped inner surface of fixing liner plate formation, the mantle body and the fixing a certain side of cone-shaped inner surface, the time and close, the time and leave.When the mantle body is drawn close fixedly cone-shaped inner surface, the material that enters crusher chamber is squeezed and flecition and being broken.In like manner, when the mantle body left fixedly cone-shaped inner surface, the material that is broken was freely discharged from the crusher chamber bottom by deadweight, finishes whole shattering process.

Gyratory crusher structural design novelty of the present utility model, compact and reasonable adopts belt wheel directly to drive the mode of power transmission shaft, has saved bevel gear pair of the prior art and excentric sleeve; Adopt underslung bearing to replace the mounting means of bowl-type of the prior art watt supporting mantle body, structure is simplified, and is easy to make, thereby makes body volume and weight reduce 30～50%.Because this gyratory crusher has adopted supporting and the installation connector of rolling bearing as the mantle body, has improved the equipment operation characteristic effectively, has improved mantle body number of oscillations, has reduced power consumption, has increased breaking capacity, can improve crushing efficiency 5～10%.This gyratory crusher can be used for metallurgy, the mine, and chemical industry and building materials etc. are the operation in small, broken bits of the various brittle materials of industry department mutually.

Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.

Fig. 1 is the structural representation of gyratory crusher.

Embodiment: can be clear that from Fig. 1, gyratory crusher of the present utility model is formed the frame of disintegrating machine by lower framework 1, middle part frame 4, upper stand 7, and the cone-shaped inner surface that the fixedly liner plates 8 that are provided with in the upper stand 7 constitute is formed crusher chamber with the mantle liner plate 6 that is arranged on the mantle body 5.Upper stand 7 is provided with one and supplies mantle body 5 to hang the cross beam frame 11 of installation, and the upper end of mantle body 5 is installed on the minor axis 9, and an end of minor axis 9 is equipped with bearing 10, and mantle body 5 is hung in the central shaft bearing sleeve 12 of cross beam frame 11 by minor axis 9 and bearing 10.The lower end of mantle body 5 is installed in the eccentric crankshaft section 14 of power transmission shaft 3 by bearing 13, and the d-axis section of power transmission shaft 3 is fixed on the frame 4 of middle part by bearing 15, and an end of power transmission shaft 3 is installed belt wheel 2.

Claims

1, a kind of gyratory crusher, comprise: lower framework, middle part frame, upper stand, the cone-shaped inner surface that forms by the fixedly liner plate that is arranged in the upper stand and be arranged on the crusher chamber that the mantle liner plate on the mantle body constitutes, it is characterized in that: upper stand is provided with a cross beam frame for the lifting of mantle body, minor axis is equipped with in the upper end of mantle body, and the mantle body relies on the bearing on the minor axis to hang in cross beam frame central shaft bearing sleeve; The other end of mantle body is plugged on the eccentric crankshaft section of a power transmission shaft by bearing.
