Problems solved by technology

At present, the method of installing a shock-absorbing spring directly under the screen frame is generally used for vibrating and flipping curved screens. On the one hand, this method has uneven shock absorption; on the other hand, for large-scale curved screens, in order to achieve the shock-absorbing effect, The size of the shock absorbing spring will be very large, which not only increases the manufacturing cost, but also greatly increases the difficulty of installation

Abstract

The invention discloses a shock absorbing device of an arc-shaped sieve and the arc-shaped sieve comprising the shock absorbing device. The shock absorbing device comprises a connecting shaft, a shock absorbing assembly, an upper spring connecting piece, a lower spring connecting piece and a buffer assembly, wherein the shock absorbing assembly is arranged between the upper spring connecting piece and the lower spring connecting piece, the buffer assembly is arranged below the lower spring connecting piece, and the connecting shaft penetrates through the upper spring connecting piece, the shock absorbing assembly, the lower spring connecting piece and the buffer assembly sequentially and then is fastened. The shock absorbing device of the arc-shaped sieve and the arc-shaped sieve comprising the shock absorbing device are simple in structure, high in stability, low in fault rate, long in service life and very high in practicability.

Description

technical field [0001] The invention relates to the field of shock absorbing devices, in particular to a shock absorbing device for a curved screen and a curved screen containing the shock absorbing device. Background technique [0002] Vibrating overturning curved screen is mainly used for dehydration, desliming, and impurity removal of selected products in wet coal preparation plants. Because the vibration motor drives the vibration of the screen frame, the material can pass through the screen surface continuously and evenly. At present, the method of installing a shock-absorbing spring directly under the screen frame is generally used for vibrating and flipping curved screens. On the one hand, this method has uneven shock absorption; on the other hand, for large-scale curved screens, in order to achieve the shock-absorbing effect, The size of the damping spring will be very large, which not only increases the manufacturing cost, but also greatly increases the difficulty o...
