DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-3 As shown, in the present embodiment, a crusher discharging buffer device comprises a discharge pipe 1, and four mounting frames 2 are fixedly connected to the inner side walls of the discharge pipe 1, and the four mounting frames 2 are staggered. A No. 1 connecting rod 3 is rotatably connected to the inner side walls of the mounting frame 2 near the upper edge, and one end of the two No. 1 connecting rods 3 is rotatably connected to a buffer plate 4, and an elastic pull rod 6 is rotatably installed on the inner side walls of the mounting frame 2, and the telescopic ends of the two elastic pull rods 6 are rotatably connected to a No. 2 connecting rod 5, and the other ends of the two No. 2 connecting rods 5 are rotatably connected to one end of the two No. 1 connecting rods 3 respectively. Among them, by arranging the elastic pull rod 6, the buffer plate 4 can be reset and shock-absorbing, so that the collision between the buffer plate 4 and the material becomes a flexible collision, reducing the direct impact of the material on the buffer plate 4, and improving the service life of the buffer plate 4, by arranging the No. 2 connecting rod 5, the elastic pull rod 6 can be pulled to extend during the rotation of the No. 1 connecting rod 3, and by arranging the buffer plate 4, the material can be blocked and guided to prevent the material from falling all the time, thereby effectively reducing the falling speed of the material.

[0022] like Figure 2 and Figure 4 As shown, a guide pipe 13 is fixedly connected to the bottom end of the feed pipe 1, and a baffle 14 is hingedly connected to the other end of the guide pipe 13. A square groove 15 is opened on one side of the baffle 14, and a plurality of buffer springs 16 are fixedly connected to one side wall inside the square groove 15, and a force-bearing plate 17 is fixedly connected to the other end of the plurality of buffer springs 16. By arranging the buffer springs 16, when the material hits the baffle 14, it can be flexibly blocked, and a reaction force can be applied to the material, thereby accelerating the stopping of the material. By arranging the guide pipe 13, the friction between the wall of the guide pipe 13 and the material can be used to reduce the movement speed of the material.

[0023] like Figure 1 and Figure 2As shown, a connecting plate 21 is fixedly connected to the top of the feed pipe 1, and a buffer pad 18 is fixedly connected to one side of the force plate 17. By setting the connecting plate 21, the feed pipe 1 can be easily fixed to the crusher body 19. By setting the buffer pad 18, the impact resistance of the baffle 14 can be improved and its service life can be improved.

[0024] like Figure 2 and Figure 3 As shown, positioning columns 8 are fixedly connected on both sides of the four buffer plates 4, and positioning grooves 9 are provided on the inner side walls of the discharge tube 1 at the positions of the eight positioning columns 8. One end of the eight positioning columns 8 are respectively slidably connected to the inside of the eight positioning grooves 9. By setting the positioning columns 8 and the positioning grooves 9, the buffer plates 4 can be positioned to prevent them from being skewed during the collision.

[0025] like Figure 2 As shown, the inner bottom surfaces of the eight positioning grooves 9 are fixedly connected with return springs 10, and the other ends of the eight return springs 10 are respectively in contact with the outer surfaces of the eight positioning columns 8, and the inner side walls of the mounting frame 2 are rotatably connected with No. 3 connecting rods 7 near the lower edge, and the other ends of the two No. 3 connecting rods 7 are respectively rotatably connected with the telescopic ends of the two elastic pull rods 6. By setting the return spring 10, the buffer plate 4 can be buffered and reset, and by setting the No. 3 connecting rod 7, the direction of the elastic pull rod 6 can be guided.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a material guide plate 11 is fixedly connected inside the discharge pipe 1 and near the upper edge, and a guide plate 12 is fixedly connected to the two side walls inside the discharge pipe 1 and above the four buffer plates 4. By setting the material guide plate 11, all materials can fall onto the adjacent buffer plates 4, and by setting the guide plate 12, it can prevent the materials from getting stuck in the gap between the mounting frame 2 and the buffer plate 4.

[0027] like Figure 2 As shown, the top of the connecting plate 21 is fixedly connected with a crusher body 19, and a conveyor belt 20 is arranged below the material guide pipe 13. The crusher body 19 is arranged to crush the material, and the conveyor belt 20 is arranged to transport the crushed material.

[0028] The utility model provides a crusher discharging buffer device, and the specific working principle is as follows:

[0029] The crusher body 19 crushes the material and then drops it into the discharge pipe 1 from the discharge port. The material accurately falls onto the buffer plate 4 under the action of the guide plate 11. The buffer plate 4 moves downward under the impact force of the material. During the movement of the buffer plate 4, the No. 1 connecting rod 3 and the No. 2 connecting rod 5 are driven to rotate. During the rotation of the No. 2 connecting rod 5, the elastic pull rod 6 is pulled to extend. During the extension of the elastic pull rod 6, the impact force generated by the material on the buffer plate 4 is converted into elastic potential energy, and the buffer plate 4 is reset by the tension generated by the release of the elastic potential energy, and during the reset process, A reaction force is applied to the material to offset the kinetic energy generated by the falling material, so that when the material completely leaves the four buffer plates 4, its falling speed is relatively small. The material then falls into the guide tube 13 and rolls obliquely in the guide tube 13, so that the material generates friction with the inclined surface of the guide tube 13 during the rolling process, thereby reducing the moving speed. When the material collides with the baffle 14, the kinetic energy generated by the material is converted into the force required to open the baffle 14, so that the initial speed of the material when it falls off the guide tube 13 is zero, further reducing the impact force of the material on the conveyor belt 20.
