Jaw breaker for concrete production

Abstract

The invention discloses a jaw breaker for concrete production. The jaw breaker for concrete production comprises a machine frame. A first edge plate is fixedly connected with the side wall of the machine frame, a conical channel is formed between the first edge plate and a second edge plate, and a fixed jaw plate is fixedly connected with the side wall of the first edge plate. A flywheel is connected with the side wall of the machine frame in a rotating mode, and an output shaft of the flywheel penetrates through the outer wall of the machine frame and is connected with the second edge plate in a rotating mode. According to the jaw breaker for concrete production, a detachable movable jaw is adopted, and therefore a new jaw plate can be conveniently replaced when the movable jaw is worn; due to the fact that an adjusting mechanism is arranged, the included angle between the fixed jaw plate and the movable jaw can be reduced according to the usage requirement, the requirement that the included angle between the fixed jaw plate and the movable jaw is smaller than the double friction angles can be met, and the material return phenomenon is eliminated; and due to the fact that a hooking claw is arranged, the hooking claw can turn over materials in the conical channel, the materials can be more easily broken, and the hooking claw can also avoid the phenomenon that the materials flyout of a feeding inlet to endanger the personal safety of an operator.

Description

technical field [0001] The invention relates to the technical field of concrete production equipment, in particular to a jaw crusher for concrete production. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials, and is widely used in civil engineering. In the processing of concrete raw materials, stones need to be crushed to obtain the fine stone aggregates required for production. The more common way is to use jaw crushers to crush stones. [0003] The existing jaw crushers have the following deficiencies during work: [0004] 1. When the jaw plate is worn, there will be a phenomenon of material return, and the jaw plate is not easy to replace; [0005] 2. The material flying out of the feed port endangers the personal safety of the operator; [0006] 3. Due to the irregularity of the material, it is easy to return the material.
