A jaw crusher for concrete production

Abstract

The invention discloses a jaw crusher for concrete production, which comprises a frame, the side wall of the frame is fixedly connected with a first side plate, and a gap is formed between the first side plate and the second side plate. The side wall of the first side plate is fixedly connected with a fixed jaw plate, the side wall of the frame is rotatably connected with a flywheel, and the output shaft of the flywheel passes through the outer wall of the frame and is rotatably connected with a second side plate. The invention adopts a detachable movable jaw, which can conveniently replace a new jaw plate when the movable jaw is worn; by setting an adjustment mechanism, the angle between the fixed jaw plate and the movable jaw can be reduced according to the use requirements, so that it meets the requirements of the fixed jaw. The included angle between the plate and the movable jaw is less than twice the friction angle to eliminate the phenomenon of material return; by setting the claws, the claws can not only turn over the materials in the tapered channel, making the materials easier to be broken, but also prevent the Material flying out of the feed port endangers the personal safety of the 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.
