[0001] The present application relates to the technical field of stone processing, and in particular to a stone crusher. Background Art
[0002] Stone crushing equipment refers to a crushing machine that can crush stones to a certain degree in proportion, and the content of particles larger than three millimeters in the discharge accounts for more than 50% of the total discharge volume. Generally, we call crushing machinery that can crush stones stone crushing equipment, which is widely used in mining, smelting, building materials, roads, railways, water conservancy and other departments. The most commonly used stone crushing equipment are: jaw crusher (roller crusher), impact crusher, impact crusher, compound crusher, cone crusher, mobile crushing station, hammer crusher and the like. When the existing stone crusher is in use, a conveyor belt is usually used to transport the stone directly into the equipment. However, when the stone is injected, due to its own weight and injection height, it will cause a large impact on the crushing roller inside the crushing equipment, which is very likely to cause damage to the crushing roller. Therefore, a stone crusher is proposed to solve the problems described in the above background technology.
[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0005] The present application provides a stone crusher adopting the following technical solution:
[0006] A stone crusher comprises a box body, a feed hopper is fixedly connected to the top of the box body, a discharge hopper is fixedly connected to the bottom of one side of the box body, a partition is installed inside the discharge hopper, a drive box is fixedly connected to the rear side of the box body, crushing rollers are symmetrically arranged inside the box body, a buffer assembly is arranged inside the box body, the buffer assembly comprises a buffer frame, the buffer frame is arranged at the bottom of the feed hopper, a plurality of slide grooves are symmetrically arranged on the inner wall of the box body, a guide rod is fixedly connected inside the slide groove, a spring is sleeved on the outer side of the guide rod, a baffle is fixedly connected to the top of the inner side of the box body, a flip plate is rotatably connected to the inner bottom of the buffer frame, a vertical rod is fixedly connected to the inner wall of the box body, and a through hole is opened at the bottom of the buffer frame.
[0007] Preferably, a motor is installed inside the drive box, and a driving gear is fixedly connected to the output end of the motor. Two rotating shafts are symmetrically arranged inside the drive box, and driven gears are fixedly connected to the ends of the two rotating shafts. The driving gear meshes with the two driven gears.
[0008] Preferably, the rotating shafts on both sides are rotatably connected inside the box, and the crushing rollers are fixedly connected to the rotating shafts.
[0009] Preferably, the buffer frame is sleeved on a plurality of guide rods, and the baffle is arranged on one side of the buffer frame.
[0010] Preferably, the through hole passes through the buffer frame, and the vertical rod is arranged at the bottom of the through hole.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] By designing a buffer component, when the stone is crushed and injected, the stone is injected through the feed hopper. When the stone is injected, it is injected into the buffer frame through the feed hopper. At this time, the material is blocked by the baffle. When the material inside the buffer frame becomes more and more, the spring on the guide rod cannot support the overall weight of the buffer frame, so that the buffer frame moves downward. At this time, the vertical rod is inserted from the through hole, so that the vertical rod lifts the flip plate, so that the flip plate flips. At this time, the baffle cannot block the movement of the stone, thereby injecting the stone into the box body. Compared with the prior art, this design can avoid the stone from being directly injected into the box body, thereby reducing the impact on the crushing roller when the stone is injected, and effectively extending the service life of the crushing roller.

When the stone is injected, it is injected into the buffer frame 11 through the feed hopper 2. At this time, the material is blocked by the baffle 15. When the material inside the buffer frame 11 becomes more and more, the spring 14 on the guide rod 13 cannot support the overall weight of the buffer frame 11, so that the buffer frame 11 moves downward. At this time, the vertical rod 17 is inserted from the through hole 18, so that the vertical rod 17 lifts the flip plate 16, so that the flip plate 16 flips. At this time, the baffle 15 cannot block the movement of the stone, so that the stone is injected into the box body 1, and finally the two crushing rollers 10 are driven to rotate by the rotating shafts 8 on both sides, so that the stone is crushed by the crushing rollers 10.
