[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-6 This utility model provides a technical solution: a raw material crusher for artificial aggregate preparation, including a shell 1, a shell cover 2, a feed pipe 3, a discharge pipe 4, a motor 5, a first cylinder 6, a partition plate 7, a clamping block 8, a clamping groove 9, a feeding block 10, a crushing knife 11, a screening plate 12, a second cylinder 13, a pressure roller 14, and a scraper 15.
[0031] The outer shell 1 is a hollow structure with an open upper surface. The lower end of the outer shell 1 is inverted conical. The upper part of the outer shell 1 is connected to the shell cover 2 by bolts. The surface of the shell cover 2 is provided with a feed pipe 3, and the lower surface of the outer shell 1 is provided with a discharge pipe 4. The outer shell 1 and the shell cover 2 together constitute the crushing chamber structure. The crushing chamber structure is equipped with a primary crushing structure. The primary crushing structure realizes the crushing process of raw materials through two sets of crushing blades 11. The primary crushing structure includes a motor 5, which is fixedly installed on the upper surface of the shell cover 2. The output end of the motor 5 passes through the surface of the shell cover 2 and is fixed. A first cylinder 6 is connected to it. Two sets of crushing blades 11 are arranged parallel to each other on the outer surface of the first cylinder 6.
[0032] like Figure 1 , Figure 5 and Figure 6 As shown, before using this device, connect the outer shell 1 and the cover 2. Insert the cover 2 along with the first-stage crushing structure into the interior of the outer shell 1, so that the smaller lower partition plate 7 first passes through the upper slot 9, and the locking block 8 on the outer surface of the partition plate 7 engages with the lower slot 9. At this time, the locking block 8 on the surface of the upper partition plate 7 engages with the upper slot 9. Connect the cover 2 to the outer shell 1 with bolts to complete the assembly of the outer shell 1 and the cover 2. Put the raw material to be crushed into the feed pipe 3, and the crushed raw material is discharged from the lower discharge pipe 4.
[0033] The outer surface of the crusher blade 11 is provided with a material collection structure. The material collection structure concentrates the raw materials to the crusher blade 11 for crushing through the partition plate 7 and the feeding block 10. The material collection structure includes the partition plate 7, which is a circular plate structure. The surface of the partition plate 7 is provided with filter holes. The outer surface of the partition plate 7 is fixedly installed with a locking block 8. The cross section of the locking block 8 is L-shaped. The locking block 8 is engaged with the locking groove 9. The locking groove 9 is fixedly installed on the inner wall of the outer shell 1. The upper surface of the partition plate 7 is fixedly installed with a feeding block 10. The feeding block 10 is a through conical plate structure with two fixedly connected sections. The feeding block 10 and the upper surface of the partition plate 7 form a bowl-shaped structure. The bowl-shaped structure encloses a set of crusher blades 11. The outer surfaces of the two sets of crusher blades 11 are respectively provided with material collection structures. The area of the upper partition plate 7 is larger than that of the lower partition plate 7. The size of the filter holes on the surface of the partition plate 7 decreases from top to bottom.
[0034] like Figure 2 , Figure 3 and Figure 4 As shown, when the raw material enters the interior of the outer shell 1, the motor 5 is started. The motor 5 drives the first cylinder 6 and the two sets of crushing blades 11 to rotate at high speed. The raw material falls through the feed pipe 3 to the upper collection structure. Under the action of the feeding block 10, it is concentrated at the upper crushing blades 11 for primary crushing. After being crushed into small particles, it passes through the filter holes on the surface of the partition plate 7 and falls into the lower collection structure. Similarly, it undergoes secondary crushing. The raw material after secondary crushing passes through the filter holes on the surface of the lower partition plate 7 and falls into the secondary crushing structure.
[0035] Below the primary crushing structure is a secondary crushing structure. The secondary crushing structure crushes the raw materials by pressing roller 14. The secondary crushing structure includes a screening plate 12, which is fixedly installed on the inner wall of the outer shell 1. The outer surface of the screening plate 12 is provided with an inverted conical protrusion. The surface of the screening plate 12 is provided with filter holes. The diameter of the filter holes on the surface of the screening plate 12 is smaller than the diameter of the filter holes in the primary crushing structure. A second cylinder 13 is fixedly installed at the center of the upper surface of the screening plate 12. The upper surface of the second cylinder 13 is provided with a cross-shaped groove. The second cylinder 13 is engaged with the lower end of the first cylinder 6. The outer surface of the second cylinder 13 is rotatably connected to the pressure roller 14. The surface of the pressure roller 14 is in contact with the surface of the screening plate 12. A scraper 15 is fixedly connected to the outer surface of the second cylinder 13. The scraper 15 is in contact with the surface of the screening plate 12.
[0036] like Figure 2 and Figure 4As shown, the raw material crushed by the crusher 11 falls onto the surface of the screening plate 12. The second cylinder 13 on the upper surface of the screening plate 12 is engaged with the lower end of the first cylinder 6. When the first cylinder 6 rotates, the second cylinder 13 will rotate accordingly. The second cylinder 13 drives the pressure roller 14 and the scraper 15 to rotate synchronously. The rotating scraper 15 crushes the raw material on the surface of the screening plate 12, further reducing the size of the raw material particles. The crushed raw material passes through the filter holes on the surface of the screening plate 12 and falls into the discharge pipe 4 below. The rotating scraper 15 cleans the surface of the screening plate 12 to prevent clogging.
[0037] Working principle: When using this artificial aggregate raw material crusher, connect the outer shell 1 and the shell cover 2 so that the primary crushing structure is inserted into the interior of the outer shell 1. Start the motor 5 and feed the raw material into the interior of the outer shell 1. The raw material falls onto the surface of the feeding block 10 and is concentrated along the feeding block 10 to the crushing blade 11 for initial crushing. The crushed raw material falls onto the surface of the screening plate 12 through the filter holes on the surface of the partition plate 7. Under the action of the rotating pressure roller 14, it undergoes further crushing and grinding. It then falls through the filter holes on the surface of the screening plate 12 and into the discharge pipe 4 below for discharge, increasing the overall practicality.
