Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present invention provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a vertical shaft impact crusher includes a mounting frame 1. Support feet 2 are fixedly installed at the bottom of the mounting frame 1. A crushing member 3 is fixedly installed at the upper end of the mounting frame 1. A crushing mechanism for acting on stones is provided inside the crushing member 3. A feeding member 4 is fixedly installed at the upper end of the crushing member 3. The feeding member 4 is a cylindrical structure with openings at both ends. A feeding adjustment mechanism for acting on stones is provided inside the feeding member 4. The feeding adjustment mechanism is composed of a guide plate 7, a drive motor 8, a central shaft 9, and a material deflecting plate 10. The central shaft 9 is rotatably installed inside the feeding member 4. The central shaft 9 is distributed along the radial direction of the feeding member 4. A plurality of material deflecting plates 10 are fixedly connected to the outer wall of the central shaft 9. The plurality of material deflecting plates 10 are arranged in a circular array. One end of the central shaft 9 is provided with a drive motor 8. The drive motor 8 is fixedly installed on the outer wall of the feeding member 4. The output shaft of the drive motor 8 is fixedly connected to the central shaft 9. A guide plate 7 is arranged above the central shaft 9. The guide plate 7 is a horn-shaped structure.

[0021] Among them, a crushing chamber 15 is opened inside the crushing member 3. A feeding port 11 penetrating the crushing member 3 is opened on the top wall of the inner cavity of the crushing chamber 15. The upper surface of the crushing member 3 is inclined downward toward the feeding port 11. A discharging opening 20 penetrating the crushing member 3 is opened at the bottom of the inner cavity of the crushing chamber 15.

[0022] The upper surface of the crushing chamber 15 is inclined downward toward the feeding port 11, which can ensure that the materials in the feeding member 4 can slide down to the feeding port 11.

[0023] Among them, the crushing mechanism is composed of a throwing plate 12 and a connecting column 13. The throwing plate 12 is located at the central position of the crushing chamber 15. The upper end of the throwing plate 12 is rotatably connected to the bottom wall of the inner cavity of the crushing chamber 15. A receiving groove 19 communicating with the feeding port 11 is opened on the upper surface of the throwing plate 12. Three throwing channels 18 extending to the outer circumferential side wall of the throwing plate 12 are opened on the inner wall of the receiving groove 19. A connecting column 13 is rotatably connected to the bottom of the throwing plate 12. An internal motor for acting on the throwing plate 12 is provided inside the connecting column 13.

[0024] The stones falling from the feeding part 4 will enter the receiving groove 19 on the throwing disc 12, and then the built-in motor in the connecting column 13 drives the throwing disc 12 to rotate. The rotation of the throwing disc 12 can throw the stones in the receiving groove 19 out from three throwing channels 18, so that the stones impact on the inner wall of the crushing chamber 15 for crushing. At the same time, the stones rebounding from the inner wall of the crushing chamber 15 will also collide with the subsequently thrown stones, thus completing the crushing of the stones.

[0025] Among them, a through groove 5 for accommodating the connecting column 13 is provided on the mounting frame 1, and three fixing plates 14 are fixedly connected between the side wall of the connecting column 13 and the inner wall of the through groove 5. The three fixing plates 14 are arranged in a circular array.

[0026] The through groove 5 can ensure the outflow of the crushed stones in the crushing chamber 15.

[0027] Among them, the fixing plate 14 is a triangular structure with a pointed top and a wide bottom.

[0028] With such a setting, the fixing plate 14 will not obstruct the falling stones, avoiding the situation where the stones fall on the upper end of the fixing plate 14 and cannot be discharged.

[0029] Among them, a discharging part 16 is fixedly installed at the bottom of the mounting frame 1, and a discharging bin 17 for acting on the stones is provided on the discharging part 16. The discharging bin 17 is a trumpet-shaped structure with a wide top and a narrow bottom.

[0030] By setting the discharging part 16 and the discharging bin 17, the crushed stones can fall concentratedly, which is convenient for the collection of the stones.

[0031] Among them, a plurality of reinforcing plates 6 are fixedly installed between the crushing part 3 and the feeding part 4. The plurality of reinforcing plates 6 are arranged in a circular array.

[0032] By setting the reinforcing plates 6, the firmness between the feeding part 4 and the crushing part 3 can be improved, avoiding the loosening of the feeding part 4.

[0033] The present utility model provides a vertical shaft impact crusher, and the specific working principle is as follows:

[0034] When in use, the stone material is introduced from above the feeding member 4, and the stone material will enter the interior of the feeding member 4 along the material guiding plate 7. At this time, the driving motor 8 is started to drive the central shaft 9 to rotate. The central shaft 9 will drive the material distributing plate 10 to rotate, and the material distributing plate 10 will evenly bring the falling stone material into the feeding member 4. Since the upper surface of the crushing member 3 is inclined downward in the direction of the feeding port 11, the stone material in the feeding member 4 will slide down along the inclined surface to the feeding port 11. By controlling the rotation speed of the central shaft 9, the feeding speed of the stone material can be controlled. The stone material falling from the feeding port 11 will enter the receiving groove 19 on the throwing plate 12, and then the built-in motor in the connecting column 13 drives the throwing plate 12 to rotate. The rotation of the throwing plate 12 can throw the stone material in the receiving groove 19 out from the three throwing channels 18, so that the stone material impacts on the inner wall of the crushing chamber 15 for crushing. At the same time, the stone material rebounding from the inner wall of the crushing chamber 15 will also collide with the subsequent thrown stone material, thereby completing the crushing of the stone material. The crushed stone material will be discharged through the discharge bin 17 on the discharging member 16.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
