Description

Easy-to-assemble on-site single-drive double-roller crusher for use in long and narrow spaces

Technical field

The invention relates to the field of crushers, and in particular to a single-drive double-toothed roller crusher suitable for use in narrow and long spaces and convenient for on-site assembly.

Background technique

At present, double-toothed roller crushers are widely used in the fields of ore and coal crushing. Usually a double-toothed roller crusher includes a base, a box, a driving part and a pair of crushing toothed rollers. Double-toothed roller crushers are divided into double drive and single drive according to the number of drive motors. Among them, the two toothed rollers of the double-drive double-toothed roller crusher are driven by an independent driving part to rotate relative to each other. In the single-drive double-toothed roller crusher, only one toothed roller is driven by the driving part, and a gear transmission is used between the two toothed rollers. To ensure synchronous relative rotation. The drive part usually consists of a motor and a reducer, or a motor and a belt drive reduction mechanism. The latter generally occupies a larger width space. Normally, a double-drive double-tooth roller crusher has two sets of drive parts arranged symmetrically in the width direction, so the width of the double-drive crusher is larger. In order to ensure a certain strength, the base and the box are designed and manufactured as one body, such as welded into a whole box. The left and right baffles of the box and the bearing seat supporting the crushing tooth roller are designed to be integrated. With this design, the base and box components of the crusher are larger in size and weight.

The Chinese patent-double-tooth roller crusher with publication number CN104069913B has two sets of drive units symmetrically arranged side by side at one end of the crusher. Each set of drive units includes a motor and a reducer; as can be seen from the attached figure, the crusher The width of the driving part of the machine exceeds the size of the crushing part.

The Chinese patent application with the announcement number CN102921499A - a new toothed roller coal crusher, and the Chinese patent application with the announcement number CN213825049U - a double-roller crusher. Both patents use two sets of transmission parts, which are respectively arranged in the crusher. At both ends of the crusher, each transmission system transmits the power of the motor to one of the crushing tooth rollers through a belt drive; in this arrangement, there is a transmission part at both ends of the crusher, which does not reduce the length of the crusher, but increases the length of the crusher to a certain extent. The width of the crusher is increased.

Under normal circumstances, after the double-tooth roller crusher is assembled and debugged in the production workshop, the complete machine is transported to the work site and installed and used. In this case, the overall dimensions of the crusher and the structure and weight of each component are not greatly restricted. However, in some use cases, the crusher is installed in a narrow and long space, with limited width and height, and heavy equipment cannot be used for overall hoisting. Therefore, it is required that the design of the crusher should meet the long and narrow working space and be modularized to facilitate on-site assembly, as well as later maintenance and repair.
