TECHNICAL FIELD
[0001] The utility model relates to the technical field of jaw crusher, especially to a conveying device with a protection mechanism for jaw crusher. BACKGROUND
[0002] The jaw crusher has the characteristics of large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance, and economic operation cost. It is widely used in mining, smelting, building materials, highways, railways, water conservancy, and chemical industry, etc. It can crush various materials with a compressive strength of not more than 320 MPa. The existing jaw crusher may add too much material at one time on the conveying device, causing the jaw crusher to be blocked and worn out. The accumulation of material may also damage the conveying mechanism and prevent the material from being added evenly to the inside of the jaw crusher.
[0003] For example, in the patent document with the publication number CN218796460U, a bulletproof jaw crusher is provided with a bulletproof mechanism on the upper side of the feeding port. The inclined baffle and the turnover baffle can prevent the broken material from being ejected upward. The rear baffle, the front baffle, and the two transparent side plates can effectively prevent the material from rolling down from above the feeding port and prevent the broken material from being ejected from the surrounding area above the feeding port. However, when the bulletproof jaw crusher is in use, the material may be added through the conveying device, which may cause the inside of the jaw crusher to be blocked and damaged, and the conveying mechanism to be worn out, resulting in a decrease in work efficiency.
