It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Combine the following Figure 1-5 The specific implementation mode of the utility model is described.

[0024] The present embodiment provides a discharging buffer system of an impact crusher, the discharging buffer system comprises a lower buffer device 10, an upper buffer device 20, and a base buffer device 30; the lower buffer device 10 comprises a lower buffer fixing seat 11 and a lower buffer frame 12, the lower buffer frame 12 comprises a reinforcing rib 13, a lower buffer plate 14, a wear-resistant plate 15, a connecting hook 16, and a lower buffer main board 17; the upper buffer device 20 comprises an upper buffer fixing seat 21 and an upper buffer plate 22, preferably, the upper buffer plate 22 is connected to the upper buffer fixing seat 21 by bolts; the base buffer device 30 comprises a base wear-resistant plate 31, preferably, the base wear-resistant plate 31 is connected to the impact crusher base by bolts.

[0025] The lower buffer device 10 is arranged at the lower side of the material discharging direction of the impact crusher, and can play a role in buffering the impact of the material discharging from the lower side.

[0026] The upper buffer device 20 is arranged on the upper side of the material discharging direction of the impact crusher, and can play a role in buffering the impact of the material discharging on the upper side.

[0027] The base buffer device 30 is arranged on the conveyor of the impact crusher, and can buffer the impact of the discharged material falling into the conveyor.

[0028] The lower buffer device 10, the upper buffer device 20 and the base buffer device 30 are respectively located in each direction of the material discharge of the impact crusher, and work together to mitigate the high-speed impact of the material discharge.

[0029] The connecting hook 16 is arranged on the upper side of the lower buffer main plate 17 , the reinforcing rib 13 is arranged on the side of the lower buffer main plate 17 , and the lower buffer plate 14 and the wear-resistant plate 15 are arranged on the other side of the lower buffer main plate 17 .

[0030] The lower buffer frame 12 is connected to the lower buffer fixing seat 11 through a connecting hook 16. The lower buffer frame 12 is connected by a movable hook. On the one hand, it is convenient for the installation and replacement of the lower buffer frame 12; on the other hand, due to the hinged effect of the movable hook connection, the impact resistance of the lower buffer device 10 can be improved.

[0031] The lower buffer frame 12 is provided with reinforcing ribs 13 to improve the strength of the lower buffer device 10 .

[0032] A plurality of lower buffer plates 14 are arranged on the side of the lower buffer main plate 17, and a wear-resistant plate 15 is arranged corresponding to each lower buffer plate 14. Figure 3 and Figure 4 As shown, the wear resistance of the lower buffer device 10 is improved; preferably, the wear-resistant plate 15 is connected to the lower buffer plate 14 by bolts. Since the upper lower buffer plate 14 is subjected to much more high-speed impact than the lower lower buffer plate 14, each lower buffer plate 14 is installed in the same manner as the lower buffer main board 17, and each wear-resistant plate 15 is installed in the same manner as the lower buffer plate 14.

[0033] When the upper lower buffer plate 14 is worn and needs to be replaced, the lower lower buffer plate 14 can be replaced to the upper side, and a new lower buffer plate 14 can be replaced to the lower side, thereby improving the utilization rate of the lower buffer plate 14 and reducing costs.

[0034] Optionally, when the lower buffer plate 14 on the upper side is worn to a certain extent but can still be used, for example, when the lower buffer plate 14 on the upper side is worn to 70%, the lower buffer plate 14 on the lower side (for example, when the lower buffer plate 14 on the lower side with the same usage time is worn to 20%) can be replaced to the upper side, and the upper lower buffer plate 14 can be replaced to the lower side, thereby improving the utilization rate of the lower buffer plate 14 and reducing the cost.

[0035] Optionally, the lower buffer plate 14 may be interchanged between left and right or between the upper left and lower right.

[0036] When the upper wear-resistant plate 15 is worn to the point where it needs to be replaced, the lower wear-resistant plate 15 can be replaced to the upper side, and a new wear-resistant plate 15 can be replaced to the lower side, thereby improving the utilization rate of the wear-resistant plate 15 and reducing costs.

[0037] Optionally, when the upper wear-resistant plate 15 is worn but can still be used, for example, when the upper wear-resistant plate 15 is worn to 70%, the lower wear-resistant plate 15 (for example, when the lower wear-resistant plate 14 with the same usage time is worn to 20%) can be replaced to the upper side, and the upper wear-resistant plate 15 can be replaced to the lower side, thereby improving the utilization rate of the wear-resistant plate 15 and reducing the cost.

[0038] Optionally, the lower wear-resistant plate 15 may be interchanged between left and right or between upper left and lower right.

[0039] The working principle of the utility model is:

[0040] After the material is crushed by the impact crusher, it will be thrown out at high speed along with the main rotor of the impact crusher. The discharge buffer system provided by the utility model is provided with corresponding buffer devices in the upper, lower and bottom directions of the discharge, which fully slows down the high-speed impact of the discharge of the impact crusher. Among them, the impact of the crushed material on the lower buffer device 10 is the most obvious, that is, the lower buffer plate 14 and the wear plate 15 of the lower buffer device 10 are the vulnerable parts of the utility model, and the lower buffer frame 12 is connected by a movable hook. When the lower buffer plate 14 and the wear plate 15 need to be replaced, the lower buffer frame 12 can be easily disassembled by hanging the lower buffer frame 12 on the hook hole, so as to replace the lower buffer plate 14 and the wear plate 15, thereby improving the efficiency of installation and replacement.

[0041] When all the crushed materials finally fall onto the conveyor, there is also a strong impact force. The discharge buffer system provided by the utility model is provided with a base buffer device 30 on the impact crusher base, which reduces the impact and wear of the crushed materials on the conveyor.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
