[0026] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0027] This embodiment introduces the specific structure of a roller crusher with a protective structure. Figure 1-Figure 3 As shown, a roller crusher with a protective structure includes:
[0028] The roller crusher body 1 has a feed opening 15 at the top thereof;
[0029] A protective box 3 is provided on the top of the roller crusher body 1 and is provided with a protective mechanism to prevent large pieces of material from entering the roller crusher body 1;
[0030] When the material enters the protective box 3, the protective mechanism includes a shaft rod 10 that passes through the box body. Both ends of the shaft rod 10 are rotatably connected to the inner wall of the protective box 3. A rotatable cylinder 11 is fixed to the outside of the shaft rod 10, and several rotating rods 9 are fixed on the cylinder 11. A fixed plate 13 is fixed on one side of the inside of the box body, and an inclined plate 7 for unloading is fixed on the other side of the inside of the box body. A motor 4 that can drive the shaft rod 10 is installed on the outside of the protective box 3. The output end of the motor 4 passes through the protective box 3 and is fixedly connected to the shaft rod 10. The motor 4 drives the shaft rod 10 to rotate, the shaft rod 10 drives the cylinder 11 to rotate, and the cylinder 11 drives the rotating rod 9 to rotate. The gap between the rotating rods 9 is adjusted, and large pieces of material that cannot pass through the gap between the rotating rods 9 will rotate with the rotating rod 9, and finally fall on the inclined plate 7 and be discharged.
[0031] When the bulk material is driven onto the inclined plate 7 by the rotating rod 9, the protective box 3 is provided with a discharge port 8 on one side of the inclined plate 7 for discharging the bulk material, and the protective box 3 is provided with a feed port 15 on one side of the fixed plate 13 for entering the material.
[0032] After the small pieces of material pass through the gap between the rotating rods 9, the bottom of the protective box 3 is open, the bottom of the protective box 3 is fixedly connected to the top of the roller crusher body 1, and the bottom of the protective box 3 is connected to the discharge port 6. The small pieces of material passing through the gap between the rotating rods 9 can directly fall into the roller crusher body 1 from the discharge port 6 and be crushed.
[0033] When large pieces of material are discharged from the discharge port 8, a rotating plate 2 is provided on one side of the discharge port 8 of the protective box 3. The rotating plate 2 is hinged to the outer wall of the protective box 3. Only when large pieces of material are discharged from the discharge port 8 will the rotating plate be driven to rotate. The discharge port 8 will be sealed at other times to prevent dust generated during crushing from leaking out and causing harm to the human body.
[0034] When the cylinder 11 drives the rotating rod 9 to rotate, the fixed plate 13 is arranged in an arc shape on the side facing the cylinder 11, so that the rotating rod 9 can rotate close to the fixed plate 13. A rectangular opening 14 is opened on the fixed plate 13, and the rectangular opening 14 is connected to the feed port 15 to facilitate the material to enter the protective box 3.
[0035] When the material slides in the fixed frame 5, a fixed frame 5 is fixed at the feed port 15 on the outside of the protective box 3, and a rotating plate 2 12 is hinged on the top of the fixed frame 5. Only when the material is added will the material push the rotating plate 2 12 to open, and the fixed frame 5 will be sealed at other times to prevent dust leakage.
[0036] In addition, the inclined plate 7 is arranged obliquely, and one side of the inclined plate 7 fixed to the inner wall of the protection box 3 is lower than the other side, so that stones falling on the inclined plate 7 are automatically discharged from the discharge port 8.
[0037] It is worth noting that the fixing frame 5 is arranged obliquely, and one side of the fixing frame 5 fixed to the protective box 3 is lower than the other side, so that the material can roll on the fixing frame 5 into the protective box 3.
[0038] Among them, the model of the roller crusher body 1 is GP86-37Y.
[0039] When the staff needs to crush the material, they turn on the motor 4, which drives the shaft 10 to rotate, the shaft 10 drives the cylinder 11 to rotate, and the cylinder 11 drives the rotating rod 9 to rotate, pouring the material into the fixed frame 5. The material will push the rotating plate 2 12 to open. The fixed frame 5 will be sealed at other times to prevent dust leakage. The material will pass through the fixed plate 13 from the fixed frame 5 and fall onto the rotating rod 9. The gaps between the rotating rods 9 are adjusted. Large pieces of material that cannot pass through the gaps between the rotating rods 9 will rotate with the rotating rods 9 and finally fall onto the inclined plate 7 to be discharged. When the large pieces of material are discharged from the discharge port 8, they will drive the rotating plate to rotate. The discharge port 8 will be sealed at other times to prevent dust leakage generated during crushing and causing harm to the human body. Small pieces of material that pass through the gaps between the rotating rods 9 can directly fall from the discharge port 6 into the roller crusher body 1 to be crushed.
[0040] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
