Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, and as shown in fig. 1-2, a roller shell of a roller crusher with a welded structure comprises a hollow shaft, an air inlet flange is fixed at one end of the hollow shaft, a speed reducer is installed at the other end of the hollow shaft, and an integrated working roller shell is fixedly sleeved on a shaft body of the hollow shaft; sealing roller sleeves are fixed at two ends of the integrated working roller sleeve, and a wear-resistant layer is welded on the outer surface of the integrated working roller sleeve in a covering manner and is at least 6 mm; an air collecting barrel is arranged at one end of the sealing roller sleeve, which is far away from the integrated working roller sleeve, and a pressing device is fixed at one end of the air collecting barrel, which is far away from the sealing roller sleeve; a support shaft is arranged at one end, located on the air inlet flange, of the hollow shaft, a drive shaft is arranged at one end, located on the speed reducer, of the hollow shaft, bearing seat groups are arranged on the support shaft and the drive shaft, and positioning blocks are arranged on the drive shaft and the support shaft; the pressing device comprises a pressing block and a top plate, the pressing block is embedded at the tail end of the wind collecting barrel, one side of the top plate is fixed on the positioning block through a screw, and the other side of the top plate is fixed on the pressing block through a screw.

This does the utility model discloses well roller crusher's overall structure, the operating temperature of roller crusher when broken material is higher, and simultaneously, roller crusher passes through two broken objects of relative pivoted round roll, consequently presss from both sides the dress roller shell and can effectively protect the round roll, prolongs the life of breaker, reduces working cost.

As shown in fig. 3, a support plate is welded on the inner surface of the integrated working roll sleeve, a fixed plate is welded on the inner surface of the integrated working roll sleeve, and a ventilation groove is formed in a gap between each adjacent support plate and the corresponding fixed plate; the total number of the supporting plates is 10, the total number of the fixing plates is 4, the supporting plates and the fixing plates are uniformly arranged on the inner surface of the integrated working roll sleeve, and the total number of the formed ventilation grooves is 12.

The utility model discloses in, through the mode of welding backup pad and fixed plate, form the ventilation groove, cooperation hollow shaft and air inlet flange, at roll crusher during operation, cold air gets into from the tip of hollow shaft, forms high-speed cold air stream through the ventilation groove, cools off the cooling to the hollow shaft.

The outer surface of the hollow shaft is provided with a flat key which is clamped between the fixing plates; the roller sleeve is positioned by the flat key and the fixing plate, so that the roller sleeve is prevented from sliding relatively in work.

Roll crusher passes through the broken material of relative rotation between the round roller, consequently, the round roller must have this very big wearing and tearing in work, behind the suit roller shell, can the preferential wearing and tearing roller shell the utility model discloses in, at the roller shell surface of installing additional, the welding has at least 6 mm's wearing layer, when carrying out the material breakage, can consume the wearing layer earlier, after the wearing layer wearing and tearing, also need not to dismantle the roller shell, directly weld the benefit in wearing and tearing station can, labour saving and time saving, material saving, through this kind of welded structure's roller shell, expensive high temperature resistant wear-resisting alloy steel casting roller shell has been replaced, in cost, the roller shell of this structure compares alloy casting roller shell and has reduced more than 50%, very big saving the fund.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
