Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a feeding mechanism of a jaw crusher. Background Art

[0002] Jaw crusher is a commonly used equipment in traditional brick and tile industry and mining machinery industry. When feeding the jaw crusher, the material needs to be put into the jaw crusher through the feed port. The feed port is usually connected to the jaw crusher. When the staff feeds too much material, the jaw crusher may be stuck. Due to its integral structure, it is troublesome to maintain. Therefore, the prior art provides a device for feeding the jaw crusher.

[0003] For example, the utility model patent with application number CN202311721246.3 discloses a continuous feeding type jaw crusher, including a body and an auxiliary device. A movable jaw body is arranged on the surface of the body, a movable jaw plate body is arranged on the inner wall of the body, a fixed seat is fixedly connected to one side of the body, a motor is arranged above the fixed seat, the output end of the motor is connected to the movable jaw body through a belt transmission, and the auxiliary device is arranged on the surface of the body. The auxiliary device includes a stabilizer bar. There are four stabilizer bars, and the four stabilizer bars are fixedly connected to the surface of the body. This continuous feeding type jaw crusher is convenient for auxiliary equipment to load and crush by arranging the auxiliary device, which can effectively reduce the existing continuous feeding type jaw crusher which mainly carries out continuous feeding through a conveyor belt. However, during feeding, due to the small capacity of the body feed port, long-term continuous feeding is likely to cause material overflow, and excessive feeding is likely to cause poor crushing effect of the equipment, thereby improving the overall practicality of the equipment.

[0004] Although the continuous feeding jaw crusher can expand the capacity of the feed port by setting auxiliary devices, the jaw crusher may also get stuck during operation due to excessive material feeding. The above-mentioned device does not have the effect of buffering the feeding. When too much material is fed, it is easy to cause the jaw crusher to get stuck. Further improvement is needed.
