Problems solved by technology

In order to overcome the difficulty of spring replacement, some technicians have improved the installation structure of the rubber spring of the vibrating screen. The rubber spring is installed on the side of the screen box, and the lower support plate and the screen box are connected by bolts. However, in this improved technology, there are There are serious problems, such as during the operation of the vibrating screen, there are serious impacts, which generate a lot of noise, and the rubber spring can only be compressed but not stretched. The new spring cannot automatically deform during the replacement process. Does not fit smoothly between the screen boxes, so the practicality of this invention is questionable

Abstract

The invention discloses a novel mounting structure of a rubber spring of a vibration screen and a method for replacing the rubber spring. The novel mounting structure has the characteristics of variable stiffness and easy replacement. The structure mainly comprises an upper supporting plate, a lower supporting plate, main rubber springs, secondary rubber springs, pressing plates and first high-strength bolts, wherein the upper supporting plate is fixed to a screen box; the main rubber springs are positioned between the upper supporting plate and the lower supporting plate; the secondary rubber springs are positioned above the upper supporting plate and corresponding to the main rubber springs, and the pressing plates are positioned above the secondary rubber springs; the pressing plates, the secondary rubber springs, the main rubber springs, the upper supporting plate and the lower supporting plate are integrally connected through the first high-strength bolts. The novel mounting structure is reasonable, and convenient to dismount and replace, facilitates equipment repair, and can prolong the service life and improve the usage efficiency of equipment; meanwhile, the supporting stiffness of the screen box can be adjusted by changing the stiffness of the secondary rubber springs, so as to meet the amplitude requirements of different working conditions.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a rubber spring installation structure of a vibrating screen and a rubber spring replacement method capable of realizing variable stiffness functions and simple spring replacement. Background technique [0002] Vibrating screen is a kind of mechanical equipment widely used in various industries such as mining, oil extraction, agriculture, construction, etc. It can realize functions such as screening, dehydration, and de-intermediation. The screen box of the vibrating screen and the installation base are connected by a damping spring. Commonly used damping springs include metal springs, rubber springs, and composite springs. Due to the low cost of rubber springs, good vibration damping effect, and good cold resistance, air tightness, waterproof, electrical insulation and other advantages, rubber springs have become the first choice for vibration damping springs in vibrating screen equipment. ...
