[0001] The utility model relates to the technical field of crushing equipment, in particular to an impact-type high-efficiency fine crusher. Background Art

[0002] The impact crusher is also called the impact crusher. It is a type of crusher that adopts the production principle of impact crushing. It has a good crushing effect on materials with low brittleness and hardness. When working, the materials in the crushing chamber are hit by the impact hammer and collide with the impact plate, and the materials will collide, strike, impact, shear and squeeze with each other, thereby achieving the purpose of crushing the stone raw materials.

[0003] The existing impact crusher has a simple internal structure. During the crushing process, the raw materials bounce inside the casing. However, during the bouncing process, the impact force between the impacted crushed stones and the newly entered crushed stones is relatively small.

[0004] Therefore, the present application provides an impact-type high-efficiency fine crusher to meet the needs. Utility Model Content

[0008] The force storage component also includes a jacket, a slide rod and an elastic part. The jacket is arranged on the outer wall of the casing, and the jacket is provided with an inner cavity connected to the outside. The slide rod is slidably connected in the inner cavity. The slide rod is hinged to the upper impact plate through the connecting component, and an elastic part is pressed between the slide rod and the inner cavity. The force storage component provides the upper impact plate with a force storage function. When the material collides with the upper impact plate, it can be rebounded, thereby accelerating the crushing of the materials.

[0009] Preferably, the elastic part includes a No. 1 spring and a No. 2 spring, the slide rod is a T-shaped part, and the No. 1 spring is pressed between the slide rod and the bottom of the inner cavity, the top of the outer sleeve is threadedly connected to a cover plate, and the No. 2 spring is pressed between the cover plate and the slide rod.

[0010] Preferably, the connecting assembly includes a connecting plate, an adjustment hole and a connecting rod. The connecting plate is arranged on the outer wall of the upper impact plate and is symmetrically arranged. The upper impact plate is provided with an adjustment hole. The end of the sliding rod is provided with a through hole. The through hole and the adjustment hole are adapted to each other, and the two are connected by a connecting rod. The end of the connecting rod is threaded with a nut.

[0011] Preferably, the drainage mechanism includes a drainage plate and a telescopic rod, one end of the drainage plate is hinged to one end of the upper impact plate, and the free end of the drainage plate is slidably connected to the telescopic rod provided on the outer wall of the casing.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-5 The shown high-efficiency impact crusher includes a casing 1 and a rotor 2. The rotor 2 driven by a motor is provided in the bottom space inside the casing 1. Its function is to cooperate with the lower impact plate 4, upper impact plate 6, and front impact plate 5 set up in the internal space of the casing 1 to crush the material so that it can pass through the screen frame 3 below the rotor 2.

[0024] In order to accelerate the crushing process of the material and make it crushed more fully, a force storage component 7 connected to the upper impact plate 6 is provided on the casing 1. The main function of the force storage component 7 is that after the rotor 2 throws out the material, when the thrown material contacts the upper impact plate 6, since the bottom end of the upper impact plate 6 is hinged to the inside of the casing 1 and its outer wall is hinged to the force storage component 7, the upper impact plate 6 flips with the hinge point as the center of the circle and accumulates force through the force storage component 7. Then, the stored potential energy is released, so that the gravel quickly collides with the material below, and the two collide to accelerate the crushing effect.

[0025] The drainage mechanism set up at the end of the upper impact plate 6 cooperates with the sliding upper impact plate 6 to always keep the feed port position of the casing 1 in an expanded state so that the material can still be put in normally during the use of the upper impact plate 6.

[0026] Force storage component 7: The outer sleeve 71 is a cylindrical structure, and its end face is provided with an inner cavity 72 that communicates with each other from top to bottom (its structural cross-section is T-shaped). A cover plate is threadedly connected to the top of the inner cavity 72, and a T-shaped slide rod 73 is slidably connected inside the inner cavity 72. The slide rod 73 is connected to the upper impact plate 6 through a connecting component, and two groups of springs are provided inside the inner cavity 72, namely No. 1 spring 74 and No. 2 spring 75. The No. 1 spring 74 is sleeved on the slide rod 73, and the No. 2 spring is pressed between the slide rod 73 and the cover plate. The cooperation of the two groups of springs makes the slide rod 73 in a balanced state under normal conditions. After use, the two groups of springs cooperate with each other to make the upper impact plate 6 reciprocate.

[0027] Connecting assembly: Two groups of symmetrically arranged connecting plates 61 are provided on the outer wall of the upper impact plate 6, and both groups of connecting plates 61 are provided with waist-shaped adjustment holes 62, and a through-hole adapted to the adjustment hole 62 is provided at the end of the sliding rod 73. The adjustment hole 62 and the through-hole are connected by a connecting rod 8 to realize the connection between the two, and the structure is locked by a nut threadedly connected to the end of the connecting rod 8 to prevent the connecting rod 8 from falling off from the hole.

[0028] Drainage mechanism: A drainage plate 9 is hinged on the upper impact plate 6 near the feed port, and the drainage plate 9 extends out of the feed port, and a guide rail 91 is provided on its outer wall. Two groups of guide rails 91 are symmetrically arranged, and a T-shaped connector 11 is slidably connected in the guide groove 92 provided on the opposite surface. The connector 11 cooperates with the telescopic rod 10 set on the outer wall of the casing 1, so as to match the impact plate 6 and the force storage assembly 7 for adjustment, so as to ensure that the feed port is always in a flared state to avoid affecting the input of materials.

[0029] The working principle of this utility model is as follows: by feeding the material from the feed port of the casing 1, the rotor 2 is controlled to rotate inside the casing 1 under the drive of the motor to crush the input material. During the rotation of the rotor 2, the material is thrown onto the lower impact plate 4, the front impact plate 5, and the upper impact plate 6. Under the action of the impact plate, the materials collide with each other to assist in crushing, and finally pass through the screen frame 3 under the rotor 2 to realize the crushing and screening of the material.

[0030] After the material has been loaded, the feed container 7 is turned back to the feed container 7 by turning the feed container 7 so that the feed container 7 can be turned back to the feed container 7 by turning the feed container 7 into the feed container 7.

[0031] The electromechanical connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, which belongs to common knowledge.

[0032] Components not described in detail herein are prior art.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
