[0024] Embodiment:

[0025] Please refer to Figures 1-5 The present application provides the following technical scheme: a multi-stage gravel impact device, comprising a material throwing impact device and a conveyor 40.

[0026] The material throwing impact device is composed of an impact cylinder 10, a material throwing device 20 and a lower hopper 30, the material throwing device 20 is arranged in the inner cavity of the impact cylinder 10, and the inner cavity of the impact cylinder 10 is composed of multiple impact cavities 101;

[0027] The inner wall of each impact cavity 101 is distributed with crushing teeth 102, and the crushing teeth 102 of each impact cavity 101 correspond to one specification respectively, the crushing teeth 102 of the uppermost layer have the largest specification, and the crushing teeth 102 of the lowermost layer have the smallest specification, so as to process the crushing work of large particles to small particles;

[0028] The material throwing device 20 is composed of a feeding port 201, a material throwing cylinder 202 and a material throwing motor 203, a guide plate is arranged in the material throwing cylinder 202, and through grooves are equidistantly formed on the material throwing cylinder 202, and the gravel is injected into the material throwing cylinder 202 from the feeding port 201; the bottom of the material throwing cylinder 202 is provided with the material throwing motor 203, the material throwing motor 203 drives the material throwing cylinder 202 to rotate, the gravel in the material throwing cylinder 202 is thrown out through the through grooves, and then the gravel is thrown onto the crushing teeth 102 on the inner wall of the impact cavity 101 to complete the gravel work;

[0029] A material leakage disc 204 is arranged below the lowermost impact cavity 101, a through material leakage groove 205 is formed on the material leakage disc 204, the crushed fine gravel falls into the lower hopper 30 through the material leakage groove 205, and then falls on the conveyor 40 through the lower hopper 30 and is conveyed outward;

[0030] The middle of the leakage disc 204 is provided with a sliding hole, the bottom of the throwing material motor 203 is provided with a telescopic base 207, and the telescopic base 207 is inserted into the sliding hole of the leakage disc 204, the bottom of the telescopic base 207 is connected with a telescopic cylinder 206, the telescopic cylinder 206 drives the telescopic base 207 to move up and down, so as to drive the throwing material cylinder 202 to move up and down, the relative position between the throwing material cylinder 202 and the impact chamber 101 is adjusted through displacement, so that the throwing material cylinder 202 corresponds to different crushing teeth 102;

[0031] The outer side of the telescopic cylinder 206 is sleeved with a protective cylinder 208, the top of the protective cylinder 208 is installed on the bottom of the leakage disc 204, and the telescopic cylinder 206 is fixed in the inner cavity of the protective cylinder 208, which plays a protective role on the telescopic cylinder 206 when the leakage groove 205 is used for stone leakage;

[0032] The bottom outer side of the protective cylinder 208 is provided with symmetrically arranged extension rods 209, the other ends of the extension rods 209 extend to the inner wall of the impact cylinder 10 and are fixed by welding; the radius of the protective cylinder 208 is half of the radius of the leakage disc 204, and the installation of the protective cylinder 208 does not affect the stone leakage of the leakage groove 205;

[0033] The scheme proposes a multi-level impact crushing device to meet different crushing requirements. When the work starts, the stones enter the throwing material cylinder 202 through the feeding port 201. The horn shape of the feeding port 201 and the sealing device at the connection with the conveying equipment ensure that the stones can smoothly and centrally enter the throwing material cylinder 202. The throwing material cylinder 202 is provided with a guide plate to guide and disperse the stones, so that the stones are uniformly distributed in the cylinder. Due to the rotating movement of the throwing material cylinder 202, the stones are thrown out through the equidistant grooves on the cylinder wall under the action of centrifugal force, so that the stones collide with the crushing teeth 102 on the inner wall of the impact chamber 101;

[0034] The stones are subjected to concentrated impact force at the collision point of the crushing teeth 102, so that the particle stones produce cracks along the weak surface inside and are crushed, completing the crushing work. At the same time, different specifications of the crushing teeth 102 are arranged at different positions of the impact chamber 101, and different specifications of the crushing teeth 102 can cope with stones of different diameters, so that the crushing is more thorough;

[0035] The fine stones after the last stage impact chamber 101 crushing fall on the leakage disc 204 below the lowermost impact chamber 101. The leakage disc 204 is provided with a through leakage groove 205, and the fine stones fall into the discharge hopper 30 through the leakage grooves 205. The fine stones finally fall on the conveyor 40. The conveyor 40 conveys the fine stones outward through the movement of the conveying belt;

[0036] The telescopic cylinder 206 can drive the telescopic base 207 to move up and down. The telescopic base 207 is installed at the bottom of the material throwing motor 203 and is inserted into the sliding hole of the material leakage disc 204. The up and down movement of the telescopic base 207 drives the material throwing cylinder 202 to move up and down. In this way, the relative position of the material throwing cylinder 202 and the impact cavities 101 of different levels can be adjusted, so that the material throwing cylinder 202 can correspond to the crushing teeth 102 of different specifications;

[0037] For example, when coarse crushing of large-particle gravel is required, the telescopic cylinder 206 can lift the material throwing cylinder 202, so that the gravel is mainly thrown to the crushing teeth 102 of the uppermost impact cavity 101; when finer crushing of medium-particle gravel is required, the telescopic cylinder 206 can lower the material throwing cylinder 202, so that the gravel is thrown to the crushing teeth 102 of smaller specifications in the lower impact cavities 101, which is very convenient;

[0038] At the same time, the protective cylinder 208 sleeved outside the telescopic cylinder 206 can protect the telescopic cylinder 206 when the material leakage groove 205 leaks material, so as to ensure the stable operation of the whole device.

[0039] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
