[0022] A jaw crusher unloading buffer device includes a shell 1, an upper end face of the shell 1 is provided with a feed port 2, a lower end face of the shell 1 is provided with a discharge port 3, a plurality of guide plates 5 are fixedly installed on the left and right end faces of the interior of the shell 1, and the plurality of guide plates 5 are all inclined. A fixed shaft 6 is fixedly installed inside the shell 1, and the fixed shaft 6 is arranged below the guide plate 5. A buffer plate 7 is arranged below the guide plate 5, and the buffer plate 7 is arranged corresponding to the guide plate 5, and one end of the buffer plate 7 is rotatably connected to the fixed shaft 6. A spring 8 is fixedly installed between the buffer plate 7 and the inner wall of the shell 1, and a plurality of buffer plates 7, fixed shafts 6 and springs 8 are provided corresponding to the plurality of guide blocks, and are symmetrically arranged. The shell 1 is trapezoidal.

[0023] The gravel enters the shell 1 through the feed port 2, is diverted by the limit block 4, and contacts the buffer plates 7 on both sides respectively to buffer the falling potential energy of the gravel. The gravel contacts the buffer plates 7, causing the buffer plates 7 to deflect around the fixed axis 6 and squeeze the spring 8, which deforms to buffer the falling potential energy. After buffering, the gravel continues to fall and contacts another set of buffer plates 7, and is buffered again. The last buffer plate 7 will return to its original position under the action of the spring 8.

[0024] The utility model provides a buffer plate 7, which diverts the crushed stones through the limit block 4 and drops onto the buffer plate 7, where it is buffered by the spring 8, thereby buffering the falling potential energy of the crushed stones.

[0025] A limit block 4 is fixedly installed inside the feed port 2, and the limit block 4 divides the feed port 2 into two groups.

[0026] Slide blocks 9 are fixedly mounted on both sides of the upper end surface of the buffer plate 7 , and slide rails 10 are slidably connected to the outer surfaces of the slide blocks 9 .

[0027] A cleaning plate 11 is fixedly installed between the two sets of slide rails 10 , and the cleaning plate 11 is arranged close to the buffer plate 7 .

[0028] A support rod 12 is provided on the lower side of the fixed shaft 6 , and the support rod 12 is fixedly connected to the housing 1 .

[0029] At the same time, when the buffer plate 7 deflects, under the action of gravity, the cleaning plate 11 will slide down close to the buffer plate 7 to clean the gravel left on the buffer plate 7. When the buffer plate 7 returns to its original position, under the pulling force of the pull rope 13, the cleaning plate 11 will return to its original position and perform a secondary cleaning process.

[0030] A pull rope 13 is connected to the outer surface of the support rod 12 . One end of the pull rope 13 is fixedly connected to the cleaning plate 11 , and the other end is fixedly connected to the lower end of the buffer plate 7 .

[0031] The utility model provides a cleaning plate 11. When the buffer plate 7 buffers the gravel, the cleaning plate 11 simultaneously cleans the upper end surface of the buffer plate 7, thereby preventing the gravel from accumulating on the buffer plate 7 and affecting the normal operation of the equipment.

[0032] Working principle: The gravel enters the shell 1 through the feed port 2, is diverted by the limit block 4, and contacts the buffer plates 7 on both sides respectively to buffer the falling potential energy of the gravel. The gravel contacts the buffer plates 7, causing the buffer plates 7 to deflect around the fixed axis 6 and squeeze the spring 8. The spring 8 is deformed to buffer the falling potential energy. After the buffering is completed, the gravel continues to fall and contacts another set of buffer plates 7, and then is buffered again. The last buffer plate 7 will return to its original position under the action of the spring 8. At the same time, when the buffer plate 7 deflects, under the action of gravity, the cleaning plate 11 will slide down close to the buffer plate 7 to clean the gravel left on the buffer plate 7. When the buffer plate 7 returns to its original position, under the tension of the pull rope 13, the cleaning plate 11 will return to its original position and perform a secondary cleaning process.
