Detailed Description

Examples

Fig. 1 is a schematic structural view of an embodiment of a buffering and blanking device of a jaw crusher. As shown in the figure, the buffering and blanking device of the jaw crusher comprises a shell 2 arranged above a crushing cavity 1, and the bottom end of the shell 2 is fixedly connected with the jaw crusher body. The top of shell 2 is provided with feed inlet 3, and feed inlet 3 is funnel-shaped structure. Feed inlet 3 and shell 2 structure as an organic whole, feed inlet 3 is located the below of conveyer belt, and the material on the conveyer belt enters into in the shell 2 through feed inlet 3.

A dust blocking structure is arranged between the shell 2 and the feed inlet 3 and comprises two semicircular baffles 4, and the diameter of each baffle 4 is slightly smaller than the inner diameter of the shell 2. A gap is provided between the two baffle plates 4 to allow the baffle plates 4 to rotate freely. One end of the baffle 4 is rotatably connected with the inner surface of the shell 2, and an inclined spring 5 is arranged between the lower surface of the baffle 4 and the inner surface of the shell 2. When the baffle 4 is positioned at the horizontal position, the spring 5 is in a natural state; when the material in the feeding hole 3 passes through, the baffle plates 4 rotate downwards under the pressure of the material, and a feeding channel is opened between the two baffle plates 4; when stopping the feeding, baffle 4 resumes the horizontality under the effect of spring 5, can play the effect that blocks to the dust in broken chamber 1, reduces the dust in broken chamber 1 and overflows through feed inlet 3. Can set up dust collector in broken chamber 1, remove dust among the dust collector who draws forth the dust in broken chamber 1 to more effective reduction dust is to the pollution of environment. The dust removing device can adopt the existing structure.

The inside of shell 2 is provided with buffer structure one and buffer structure two, and buffer structure two is located the below of buffer structure one. The buffer structure one comprises a spiral buffer groove 6, and the buffer groove 6 is fixed inside the shell 2 through a connecting plate 7.
