[0002] In many industrial fields such as construction, road construction, and mining, large amounts of stone and ore often need to be processed. The stones mined from quarries are usually too large to be used directly. Stone crushers can break these large stones into smaller particles for easier processing, transportation, and use.

[0003] Currently, traditional stone crushers typically use a high-speed rotating drum to crush and pulverize stones. However, there are some shortcomings during the crushing and maintenance processes. First, the stone is not fully crushed, and the stone crusher cannot be effectively crushed multiple times within the crusher. The output particle size is uneven and cannot be adjusted and controlled. At the same time, during the crushing process, the stone will hit the inner wall of the machine in a certain direction with the high-speed rotation of the drum. After long-term high-intensity operation, it will cause severe wear and tear on the machine, shortening its service life. Finally, the high-intensity operation of the stone crusher requires frequent maintenance. Replacement requires the entire casing to be dismantled, which is time-consuming and labor-intensive.

[0034] 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.

[0035] See also Figure 1-5In the embodiment of the utility model, a stone crushing device with a protective mechanism is provided. After the stone enters the crushing chamber, it is struck and impacted back and forth between the high-speed rotating crushing component and the impact component, so that the stone is crushed and refined multiple times, and finally reaches the required particle size requirement and is discharged, effectively improving the crushing efficiency.

[0036] Specifically, the stone crushing device in the preferred embodiment of the present invention includes a body 1, an impact assembly 2, a crushing assembly 3, and a drive assembly 4. The body 1 includes a crushing chamber 101, which is arranged inside the body 1. A feed port 102 and a discharge port 103 are formed at the top and bottom of the crushing chamber 101, respectively, and are connected to the crushing chamber 101. The feed port 102 is arranged at an angle. Stones slide into the crushing chamber 101 through the feed port 102 for crushing. After the crushing is completed, they slide out from the discharge port 103.

[0037] The crushing assembly 3 is arranged in the crushing chamber 101 and is used to crush the stone; the impact assembly 2 is arranged on the inner wall of the body 1 and on the side opposite to the feed port 102, and is used for the impact plate to crush the stone again after the stone collides with the impact plate after high-speed rotation; the driving assembly 4 is arranged on one side of the body 1 and is connected to the crushing assembly 3, and the driving assembly 4 drives the two ends of the crushing assembly 3 to operate.

[0038] The counterattack assembly 2 includes a counterattack plate 201, a base 202 and a handle 203; the base 202 is detachably connected to the inner wall of the body 1; the counterattack plate 201 is detachably connected to one side of the base 202 and matches the notch formed on the inner wall of the body 1; a handle 203 is also provided on the other side of the base 202 for conveniently taking the counterattack plate 201 when replacing it.

[0039] During the actual setting process, the new preferred feed port 102 of the present invention is inclined. The inclined design allows the stone to slide smoothly by its own gravity, reducing the residence time of the stone at the feed port 102. The stone can be evenly dispersed before entering the crushing chamber 101, reducing the risk of blockage. At the same time, the stone has a longer crushing path in the crushing chamber 101, and the stone can be crushed more fully, thereby improving the crushing effect.

[0040] In actual use, if the gap between the impact plate and the crushing assembly is large, the stone particle size produced by the device is large, and if the gap between the impact plate and the crushing assembly is small, the stone particle size produced by the device is small. Based on this, the impact plate 201 of the present invention is provided with specifications of different thicknesses. By replacing the impact plate 201 of different thicknesses, the gap between the crushing assembly 3 and the impact plate 201 can be adjusted, thereby controlling the size of the crushed particles to meet actual crushing needs.

[0041] More specifically, the utility model preferably has an inner wall of the machine body 1 corresponding to one side of the impact assembly 2 in an arc shape; and the direction of the arc corresponds to the tilt direction of the feed port 102 .

[0042] In the actual setting process, if Figure 2 As shown in the figure, the preferred impact plate 201 of the present invention is inclined serrated. The serrated impact plate causes the material to generate a larger local specific pressure when it hits the serrated tooth edge. Compared with the flat serrated structure, it can provide a more concentrated impact point, thereby more effectively crushing the material. At the same time, the serrated impact plate forms a certain inclination angle with the bottom surface, which can increase the residence time of the stone in the crushing chamber, and the stone has more opportunities to be repeatedly impacted, thereby further refining and crushing.

[0043] In a preferred embodiment, Figure 3 As shown in the figure, the outer surface of the body 1 is also provided with an opening and closing door 104, which corresponds to the position of the counterattack assembly 2. When the counterattack plate 201 is worn or needs to be replaced as needed, the operator opens the opening and closing door 104, takes the counterattack assembly 2 through the handle 203, and disassembles and reassembles the counterattack plate 201.

[0044] Furthermore, if Figure 4 As shown in the figure, the preferred crushing assembly 3 of the present invention includes a main shaft 302, a hammer 301 and two bearing bases 303; the main shaft 302 runs through the body 1, and the two bearing bases 303 are respectively arranged on both sides of the body 1. The two bearing bases 303 are connected to the two ends of the main shaft 302 to support the main shaft 302 and ensure the stability of the main shaft 302 when rotating; at the same time, a hammer 301 is provided on the outer surface of the main shaft 302 for impacting and crushing stones.

[0045] In the actual setting process, it is preferred that there are several hammer pieces 301, which are evenly distributed along the length direction of the main shaft 302. The side of the hammer piece 301 that contacts the stone is arc-shaped, so that the hammer piece 301 and the stone have a larger contact area and are in full contact, thereby improving the working efficiency of the crusher.

[0046] Furthermore, the preferred drive assembly 4 of the present invention includes a drive wheel 403, a belt 402 and a motor 401; wherein the drive wheel 403 is arranged on one side of the body 1 and is connected to one end of the main shaft 302 in the crushing assembly 3, and the motor 401 is arranged on one side of the body 1 and is connected to the drive wheel 403 through the belt 402. When the motor 401 is running, the drive wheel 403 is driven to rotate through the belt 402, thereby driving the main shaft 302 to operate.

[0047] Furthermore, the new preferred stone crusher of the present utility model also includes a accommodating box 5, which is arranged below the crushing chamber 101 and corresponds to the position of the discharge port 103, and is used to collect the crushed stones discharged from the discharge port 103.

[0048] Furthermore, if Figure 5 As shown in the figure, the body 1 of the present invention further includes a safety window 105, a latch 106, and a hook 107. The safety window 105 is provided on the outer surface of the body 1 for operators to observe the internal state of the body 1, which helps to detect abnormal conditions in a timely manner; the latch 106 is provided on one side of the safety window 105 and is used to open and close the safety window 105, which helps to prevent the safety window 105 from being accidentally opened when the crusher is in operation; the hook 107 is provided on the upper surface of the body 1 for hoisting the crushing device by a steel rope through the hook 107 when the crushing device needs to be operated at a height.

[0049] Working principle: The stone slides from the feed port into the crushing chamber for crushing, and the hammer hits the stone for initial crushing, and then is thrown to and hits the impact plate for further crushing, and then bounces back from the impact plate to the crushing area of ​​the hammer head for further crushing. The stone collides back and forth between the crushing component and the impact component until it reaches the crushing particle size requirement, and the stone can be discharged from the discharge port to the containing box through the gap between the crushing component and the impact component.

[0050] The stone crushing device of the utility model has an impact plate installed on the inner wall of the machine body, and the worn impact plate can be replaced through the opening and closing door on the machine body. The operation is simple and convenient, which avoids direct contact between the machine body and the stone, reduces the wear of the stone crusher, improves the crushing efficiency and extends the service life.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
