It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Example 1

[0027] Reference Figure 1-3 A limestone crushing device comprises a crushing box 1, a pretreatment box 2 and a feeding port 3. The pretreatment box 2 is fixed on the top of the crushing box 1, and the feeding port 3 is fixed at one end of the top of the pretreatment box 2. The feeding port 3 is connected to the pretreatment box 2. A pretreatment mechanism is installed inside the pretreatment box 2, and the pretreatment mechanism is used for preliminary crushing of the limestone. A crushing mechanism is installed inside the crushing box 1, and the crushing mechanism is used for secondary crushing of the limestone.

[0028] The pretreatment mechanism comprises a power assembly and a guide assembly. The power assembly is mounted inside the pretreatment box 2, and the guide assembly is mounted inside the power assembly.

[0029] The power assembly includes a first motor 4, a swing rod 5, a positioning shaft 6, a matching ring 7 and an extrusion plate 8. The first motor 4 is fixed to one side of the pretreatment box 2. The output end of the first motor 4 passes through the pretreatment box 2, and the swing rod 5 is fixed to the inner side. The positioning shaft 6 is fixed to one end of the swing rod 5. The outer side of the positioning shaft 6 is slidably connected with the matching ring 7. The inner side of the matching ring 7 is clearance-matched with the positioning shaft 6. The outer side of the matching ring 7 is fixed with an extrusion plate 8. The extrusion plate 8 is slidably connected to the inner side of the pretreatment box 2. The side of the extrusion plate 8 away from the matching ring 7 is evenly provided with pointed protrusions to increase the crushing effect of the extrusion plate 8 on the limestone.

[0030] The guide assembly includes a guide rod 9, a vertical plate 10, a matching groove 11, a return spring 12, a limit cap 13 and a discharge port 14. One side of the bottom of the extrusion plate 8 is rotatably connected to the guide rod 9 through a pin. The outer side of the guide rod 9 is equipped with a vertical plate 10. The bottom of the vertical plate 10 is fixed to the pretreatment box 2. The inner side of the vertical plate 10 is provided with a matching groove 11 corresponding to the position of the guide rod 9. The matching groove 11 and the guide rod 9 are clearance-matched. The outer side of the guide rod 9 and the position deviating from the vertical plate 10 are sleeved with a return spring 12. One end of the return spring 12 is fixed to the vertical plate 10, and the other end of the return spring 12 is fixed with a limit cap 13. The limit cap 13 is fixed to the guide rod 9. A discharge port 14 is provided at one end of the bottom of the pretreatment box 2 and at a position corresponding to the extrusion plate 8. When the first motor 4 is started The output end of the first motor 4 drives the swing rod 5 to rotate, so that the swing rod 5 drives the positioning shaft 6 to push the matching ring 7 to move, and then the matching ring 7 pushes the extrusion plate 8 to move. At the same time, the extrusion plate 8 pushes the limiting cap 13 to move through the guide rod 9, so that the reset spring 12 is stretched and deformed, and then the extrusion plate 8 moves in the direction close to the inner end of the pretreatment box 2. With the cooperation of the pretreatment box 2 and the extrusion plate 8, the limestone is initially crushed. After that, the swing rod 5 drives the positioning shaft 6 to continue to rotate. At this time, the bottom of the extrusion plate 8 gradually approaches the discharge port 14, and limestone continues to be added through the feeding port 3. When the swing rod 5 drives the positioning shaft 6 to rotate one circle, the extrusion plate 8 continues to extrude the limestone, and this reciprocating process is used to achieve the initial crushing of the limestone.

[0031] The crushing mechanism includes a material guide port 15 and a crushing roller 16. The material guide port 15 is opened at the top of the crushing box 1 and at a position corresponding to the feed port 14. Servo motors are fixed at both ends of one side of the crushing box 1. The output ends of the servo motors pass through the inner side of the crushing box 1 and the crushing roller 16 is fixed. Both ends of the crushing roller 16 are rotatably connected to the inner side of the crushing box 1 through bearings. It can be understood that when the limestone needs to be crushed, the two crushing rollers 16 turn in opposite directions.

[0032] Example 2

[0033] Embodiment 1 is further optimized, specifically, as Figure 4 As shown, the bottom of the crushing box 1 is equipped with a discharging mechanism, which is used to discharge the crushed limestone.

[0034] The discharging mechanism includes a discharging barrel 17, a second motor 18 and a spiral cutter 19. The discharging barrel 17 is fixed to the bottom of the crushing box 1, and the second motor 18 is fixed to one end of the discharging barrel 17. The output end of the second motor 18 passes through the inner side of the discharging barrel 17 and the spiral cutter 19 is fixed thereto. The size of the spiral cutter 19 matches the inner side of the discharging barrel 17. When the crushed limestone needs to be discharged, the second motor 18 is started, and the output end of the second motor 18 drives the spiral cutter 19 to rotate, thereby realizing the discharge of the limestone.

[0035] From the above, we can know that:

[0036] The utility model aims at the technical problem that the existing technology can crush limestone during use, but lacks pretreatment of limestone, which makes it inconvenient to crush limestone in multiple stages, resulting in unsatisfactory crushing effect; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0037] During the use and placement process, when the limestone needs to be crushed, the first motor 4 and the servo motor are started, and then an appropriate amount of limestone is added to the feeding port 3. The output end of the first motor 4 drives the swing rod 5 to rotate, so that the swing rod 5 drives the positioning shaft 6 to push the matching ring 7 to move, and then the matching ring 7 pushes the extrusion plate 8 to move. At the same time, the extrusion plate 8 pushes the limiting cap 13 to move through the guide rod 9, so that the reset spring 12 is stretched and deformed, and then the extrusion plate 8 moves in the direction close to the inner end of the pretreatment box 2. Under the cooperation of the pretreatment box 2 and the extrusion plate 8, the limestone is preliminarily crushed;

[0038] The crushed limestone falls into the crushing box 1 through the discharge port 14 and the guide port 15. At this time, the two servo motor output ends are controlled to rotate so that the servo motor output ends drive the crushing roller 16 to rotate, and the limestone is crushed for the second time, thereby realizing multi-stage crushing of the limestone.

[0039] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:
