Feeding buffer device of jaw crusher

Abstract

The invention provides a jaw crusher feeding buffer device, which includes a frame, an upper guard plate, a lower guard plate, a fixed jaw assembly, a movable jaw assembly, an eccentric wheel, a toggle plate, an adjustment seat and a spring rod, and the movable jaw There is a buffer structure between the plate and the movable jaw assembly, teeth are arranged in parallel on the fixed jaw plate and the movable jaw plate, and a screening device is installed above the movable jaw assembly and the fixed jaw assembly. The screening device includes material Box, material receiving box, transmission screen and conveyor belt, the material box and transmission screen are all set above the material receiving box, the lower part of the conveyor belt near the end of the upper guard plate is equipped with a feeding buffer device, the feeding buffer device and the upper guard plate Fixedly connected, the feeding buffer device includes a buffer bucket body, a wear-resistant plate and two buffer components. The buffer components are respectively fixed on the two inner plates of the buffer bucket body. The buffer component includes a sloping plate, a wear-resistant plate, a rubber body and a support plate. The inclined plate is connected with the rubber body through a connecting shaft, and the rubber body is arranged on the side away from the inner plate of the buffer bucket; the invention has low cost and long life.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a feeding buffer device for jaw crushers. Background technique [0002] The feeding buffer device of the jaw crusher consists of two jaw plates, the movable jaw and the static jaw, to form a crushing cavity, which simulates the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] However, the fixed jaws and movable jaws of the traditional jaw crusher feeding buffer device are mostly flat or stepped structures, and the feed is not screened, and most of the crushed materials are various ores and bulk materials. During the conveying process, large materials collide with each other, and there will be gravel and residual materials, which meet the process standards without being cr...
