Problems solved by technology

[0010] 2. Power consumption and force reduction
[0011] 3. Make noise
During the rapid movement of the toggle plate mechanism, the toggle plate and the toggle plate groove will have an instant separation phenomenon, resulting in impact sound, coupled with the creaking sound of spring expansion and contraction, which is the main noise source of the jaw crusher polluting the environment. At the same time, it also aggravates the wear and tear of parts;
[0012] 4. Limit speed
Because it is a one-way thrust, the "return" is realized by the external spring pull rod mechanism. If the speed is too high, the inertia will be large, and there will be an instant separation between the toggle plate and the toggle plate groove, so the "butting" structure is only suitable for low speed. Cannot achieve high speed operation

Abstract

The invention discloses a three-connecting rod articulating mechanism, and relates to a toggle plate mechanism of a jaw crusher. The three-connecting rod articulating mechanism comprises a driving connecting rod and two driven connecting rods; and one end of each of the two driven connecting rods is connected to the end portion of the driving connecting rod through an articulating mechanism. According to the three-connecting rod articulating mechanism, 'toggle plate structure' design of the prior art is replaced by 'connecting rod structure' design, and a previous bulky plate mechanism is changed into a rigid and light rod structure; 'collision structure' design of the prior art is replaced by innovative 'articulating structure' design, and unidirectional thrust crushing acting is changed into bidirectional push-pull crushing acting, so that the crushing functions of the jaw crusher is improved; and the jaw crusher is free of the traditional spring pull rod mechanism, and the structure of the jaw crusher is simplified.

Description

technical field [0001] The invention relates to the technical field of jaw crushers, in particular to a three-link hinge mechanism applied to jaw crushers. Background technique [0002] Jaw crusher, commonly known as jaw crusher, is one of the oldest and most widely used crushing equipment. [0003] The prior art jaw crusher has a typical structure: a set of spring pull rod mechanism is arranged at the lower end of the movable jaw. [0004] The function of setting the spring rod mechanism is to help the movable jaw to "return" after the work of crushing; [0005] The reason for setting the spring pull rod mechanism is: the jaw breaking toggle plate under the prior art is a "butting" structure (such as figure 1 shown), that is, the connection between the movable jaw and the toggle plate (marked 111 in the figure) is a "butting" movement; this "butting" structure has only "pushing force" but no "pull force". The purpose of setting the spring pull rod It is to make up for th...
