Problems solved by technology

Since the contact surface between the substrate and the dovetail chuck is flat, and the two ends are the same size, the friction surfaces are many and large, and the friction force is also large, so it is not easy to disassemble and install.

Embodiment Construction

[0007] The embodiment is described in detail in conjunction with the accompanying drawings, which includes a roller crusher roller. The main improvement point is to change the dovetail groove substrate 3 on the roller from the same size at both ends to one side with an angle of 3-6 degrees from one end to the other end. the excessive slope; also change the dovetail chuck 1 at the bottom of the tooth plate to the slope corresponding to the transition slope on the base plate of the dovetail groove, and weld a fixed slope in the transition slope of the substrate, one side is a plane and the other side corresponds to the excessive slope Iron 2, an installation oblique iron 6 is reversely inserted between the contact surface between the fixed oblique iron and the dovetail chuck. Keep the arc-shaped pressing plate 4 and its fixing bolt 5 unchanged. Through the improvement of the dovetail groove between the base plates, the present invention makes the dovetail groove between the base...

Abstract

The invention discloses a toothed-plate connection structure of a roller of a crusher. The toothed-plate connection structure comprises the roller of the roller-type crusher, wherein one side of a dovetail-groove base plate on the roller is an inclined transitional surface which inclines from one end to the other end at an inclination angle of 3-6 degrees; a dovetail-groove clamping head at the bottom of a toothed plate is changed into an inclined surface oppositely corresponding to the inclined transitional surface of the dovetail-groove base plate, a piece of inclined fixing iron is welded to the inside of the inclined transitional surface of the base plate, one side of the inclined fixing iron is a plane, the other side of the inclined fixing iron corresponds to the inclined transitional surface, and a piece of inclined installation iron is oppositely inserted into a contact surface between the inclined fixing iron and the dovetail-groove clamping head. A planar dovetail groove in the roller is changed into a trapezoid dovetail groove, the dovetail-groove clamping head on the toothed plate is correspondingly improved, and the aim that the toothed plate can be assembled and disassembled quickly with less effort is achieved.

Description

Technical field: [0001] The invention is a roller tooth plate connection structure installed and used on a roller crusher, which can facilitate the rapid installation and disassembly of the tooth plate. Background technique: [0002] In the current roller crusher, the installation and fixation between the roller base plate and the tooth plate is carried out through the dovetail groove on the roller base plate and the dovetail chuck on the tooth plate. Since the contact surfaces between the base plate and the dovetail chuck are flat, and the two ends have the same size, the friction surfaces are many and large, and the friction force generated is also large, so it is difficult to disassemble and install. Invention content: [0003] The purpose of the present invention is to provide a crusher roller tooth plate connection structure which can facilitate the rapid installation and disassembly of the tooth plates. [0004] The technical solution of the present invention is...
