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.

[0019] 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.

[0020] Combine the following Figure 1-3 The specific implementation mode of the utility model is described.

[0021] The present embodiment provides a feeding device of an impact crusher main machine, which includes a feed port assembly 1, a lifting cylinder 2, a wear-resistant plate 3, a dust-proof pressure plate 4, a rotating pin 6, a movable cover plate 7, a chain 8, and a baffle plate 9; the movable cover plate 7 is located above the feed port assembly 1, the feed port assembly 1 is fixedly connected to the impact crusher main machine, the movable cover plate 7 is connected to the impact crusher main machine through the rotating pin 6, and the two ends of the lifting cylinder 2 are respectively connected to the side of the feed port assembly 1 and the movable cover plate 7; the wear-resistant plate 3 is located on the inner side of the feed port assembly 1, and the dust-proof pressure plate 4 is located on the outer side of the feed port assembly 1, which can effectively improve the wear resistance of the feeding device and thus improve the service life of the feeding device; the chain 8 and the baffle plate 9 are located at the inlet of the feed port assembly 1, and the chain 8 and the baffle plate 9 are respectively connected to the movable cover plate 7.

[0022] Optionally, the chain 8 is connected to the movable cover plate 7 via round steel, and the baffle plate 9 is fixedly connected to the movable cover plate 7 via bolts.

[0023] Optionally, the dustproof pressure plate 4 and the material blocking plate 9 are both made of rubber material.

[0024] Optionally, a lifting cylinder 2 is respectively arranged on both sides of the feed port assembly 1; wherein, the piston end of each lifting cylinder 2 is respectively connected to the movable cover plate 7, and the cylinder end of each lifting cylinder 2 is respectively connected to the side of the feed port assembly 1; optionally, the piston end of each lifting cylinder 2 can also be respectively connected to the side of the feed port assembly 1, and the cylinder end of each lifting cylinder 2 can also be respectively connected to the movable cover plate 7.

[0025] The extension and retraction of the lifting cylinder 2 can drive the movable cover plate 7 to flip, and the flipping of the movable cover plate 7 can drive the baffle plate 9 to flip. When the baffle plate 9 flips, the distance between the baffle plate 9 and the inner side of the feed port assembly 1 can be changed, that is, the inlet size of the feed port assembly 1 can be changed.

[0026] The chain 8 and the baffle plate 9 are arranged at the inlet of the feed inlet assembly 1 to effectively prevent the splashing of fine materials after the material is crushed. When the inlet size of the feed inlet assembly 1 is small, the chain 8 and the baffle plate 9 jointly block the splashing of fine materials.

[0027] When the inlet size of the feed port assembly 1 is large, that is, the distance between the baffle plate 9 and the inner side of the feed port assembly 1 becomes larger, the baffle plate 9 cannot prevent the fine material from splashing at the lower side of the feed port assembly 1. However, due to the effect of gravity, the distance between the chain 8 and the inner side of the feed port assembly 1 does not change, that is, the chain 8 can still prevent the fine material from splashing at the lower side of the feed port assembly 1.

[0028] Optionally, the feeding device further comprises a spray assembly 5 arranged on the upper side of the movable cover plate 7, and the spray assembly 5 is fixedly connected to the movable cover plate 7 by bolts.

[0029] The spray assembly 5 is arranged on the movable cover plate 7, so that the dust can be controlled at the dust generating point, and the dust suppression effect of the impact crusher main unit is effectively improved.

[0030] The working principle of the utility model is:

[0031] The material enters the feed port assembly 1 through the feeder, and the piston extension of the lifting cylinder 2 is adjusted according to the volume of the material.

[0032] When a small volume of material enters the feed inlet assembly 1 through the feeder, Figure 1 As shown, the piston of the regulating lifting cylinder 2 is retracted. In this state, the smaller materials can smoothly enter the feed inlet assembly 1, thereby avoiding the problem of material blockage at the inlet of the feed inlet assembly 1. When the impact crusher is operating, the internal materials move at high speed driven by the rotor, while the chain 8 and the baffle plate 9 are located at the inlet of the feed inlet assembly 1 and are in a naturally drooping state, which can effectively prevent the splashing of fine materials after being crushed.

[0033] When a large volume of material enters the feed inlet assembly 1 through the feeder, Figure 3 As shown, the piston of the regulating lifting oil cylinder 2 is extended, so that the movable cover plate 7 turns upward around the rotating pin 6 and drives the baffle plate 9 to turn upward, that is, the distance between the baffle plate 9 and the inner side of the feed port assembly 1 is increased, thereby increasing the inlet size of the feed port assembly 1. In this state, larger materials can smoothly enter the feed port assembly 1, thereby avoiding the problem of material blockage at the inlet of the feed port assembly 1.

[0034] When the impact crusher is in operation, the internal materials move at high speed driven by the rotor, and when the distance between the baffle plate 9 and the inner side of the feed inlet assembly 1 increases, the baffle plate 9 cannot block the splashing of fine materials on the lower side of the feed inlet assembly 1. However, since the chain 8 is connected to the movable cover plate 7 through round steel, the chain 8 will naturally sag under the action of gravity, that is, the distance from the inner side of the feed inlet assembly 1 will not change, so the chain 8 can still block the splashing of fine materials on the lower side of the feed inlet assembly 1.

[0035] A spray assembly 5 is arranged on the movable cover plate 7, that is, the dust suppression device is arranged in the dust generating area, and water mist is generated through a plurality of spray nozzles to control the dust at the dust generating point and prevent it from spreading to the surroundings, thereby effectively improving the dust suppression effect of the impact crusher main unit.

[0036] 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.

[0037] 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.
