The block raw materials are put into the crusher through the feed inlet, and then are crushed by two identical crushing rollers inside the crusher.

[0004] However, the existing crusher crushes the block raw materials by two identical crushing rollers inside. Since the diameters of the crushing rollers are the same, it is easy to have the phenomenon that the raw materials are not completely crushed, and the raw materials need to be crushed repeatedly, increasing the workload and affecting the working efficiency.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The motor drives the main gear to rotate, and the rotation of the main gear drives the transmission gear to rotate. Therefore, the rotation speeds of the first crushing roller and the second crushing roller are the same. Due to different diameters, the linear speed of the first crushing roller is greater than the linear speed of the second crushing roller.

Due to the existence of the spiral knives, the raw material will be conveyed to the crushing knives at both ends, so that the ground raw material is crushed for the second time. Under the two-time crushing, the complete crushing of the raw material is realized. And because there is a relatively deep groove between the two sets of second crushing rollers and the first crushing roller, and since the first crushing roller is located below the second crushing roller, the acting force of the second crushing roller is obliquely downward. When the large-volume raw material is crushed, the obliquely downward force will squeeze the raw material, so that the large-volume raw material breaks into small-volume raw materials, which is more convenient for crushing. This structure is simple and easy to operate, which is beneficial to improving its use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment 1, please refer to Figures 1 - 5 , the present utility model provides a technical solution: a crushing device for raw materials for preparing autoclaved thermal insulation blocks, a second crushing roller 6 is inserted through the side surface of the main body 1 of the crusher, a transmission gear 3 is fixed at one end of the second crushing roller 6, a second baffle 13 is fixed at the other end of the second crushing roller 6, a second positive spiral knife 15 and a second reverse spiral knife 16 are fixed on the outer surface of the second crushing roller 6. Due to the presence of the spiral knife, the raw materials will be conveyed to the crushing knives at both ends, so that the polished raw materials are crushed twice, and a second crushing knife 14 is fixed on the outer surface of the second crushing roller 6;

[0026] A main gear 12 is fixed at one end of the first crushing roller 7. Since the main gear 12 is engaged with the transmission gear 3, the rotation of the main gear 12 will drive the rotation of the transmission gear 3. A motor 4 is fixed on the surface of the main gear 12. A first baffle 8 is fixed at the other end of the first crushing roller 7. A first positive spiral knife 10 and a first reverse spiral knife 11 are fixed on the outer surface of the first crushing roller 7. Due to the presence of the spiral knife, the raw materials will be conveyed to the crushing knives at both ends, so that the polished raw materials are crushed twice, and a first crushing knife 9 is fixed on the outer surface of the first crushing roller 7.

[0027] On the basis of the first embodiment, in order to achieve the complete crushing of raw materials by the crusher main body 1, a feed inlet 2 is provided on the upper surface of the crusher main body 1, a mounting plate 5 is fixed on the side surface of the crusher main body 1, and a through hole 17 is provided on the side surface of the crusher main body 1; the motor 4 is fixed on the surface of the mounting plate 5;

[0028] The transmission gear 3 and the main gear 12 are located on the side surface of the crusher main body 1 on one side of the mounting plate 5. At the same time, the transmission gear 3 and the main gear 12 are movably connected to the side surface of the crusher main body 1; the first baffle 8 and the second baffle 13 are located on the side surface of the crusher main body 1 on the other side of the mounting plate 5. At the same time, the first baffle 8 and the second baffle 13 are movably connected to the side surface of the crusher main body 1. Therefore, the crusher main body 1 will not hinder the rotation of the first crushing roller 7 and the second crushing roller 6;

[0029] There are two groups of the second crushing rollers 6. The two groups of the second crushing rollers 6 are symmetrically distributed on both sides of the first crushing roller 7, and the two groups of the second crushing rollers 6 are located above the first crushing roller 7. A relatively deep groove is formed between the two groups of the second crushing rollers 6 and the first crushing roller 7. Due to the relatively deep groove between the two groups of the second crushing rollers 6 and the first crushing roller 7, and at the same time the first crushing roller 7 is located below the second crushing roller 6, the acting force of the second crushing roller 6 is obliquely downward. When large-volume raw materials are crushed, the obliquely downward force will squeeze the raw materials, causing the large-volume raw materials to break into small-volume raw materials, which is more convenient for crushing;

[0030] The middle diameter of the second crushing roller 6 is larger than the diameters of both ends, and the middle diameter of the first crushing roller 7 is larger than the diameters of both ends. At the same time, the diameters of both ends of the second crushing roller 6 are larger than the diameter between the first crushing rollers 7, and the outer surfaces of the second crushing roller 6 and the first crushing roller 7 correspond to each other. The transmission gear 3 is driven by the main gear 12. Therefore, the rotational speeds of the first crushing roller 7 and the second crushing roller 6 are the same. Due to the different diameters, the linear speed of the first crushing roller 7 is greater than the linear speed of the second crushing roller 6. Therefore, the raw materials will be ground and crushed first at the gap between the first crushing roller 7 and the second crushing roller 6;

[0031] The first positive spiral knife 10 and the first reverse spiral knife 11 are located at the middle position of the first crushing roller 7, and the spirals of the first positive spiral knife 10 and the first reverse spiral knife 11 are opposite; the second positive spiral knife 15 and the second reverse spiral knife 16 are located at the middle position of the second crushing roller 6, and the spiral of the second reverse spiral knife 16 is opposite to that of the second positive spiral knife 15; at the same time, the first positive spiral knife 10, the first reverse spiral knife 11, the second positive spiral knife 15, and the second reverse spiral knife 16 correspond to each other and are staggeredly clamped. Due to the existence of the spiral knives, the raw materials will be conveyed to the crushing knives at both ends, causing the polished raw materials to be crushed for the second time;

[0032] The first crushing knife 9 is fixed on the outer surfaces at both ends of the first crushing roller 7, and the second crushing knife 14 is fixed on the outer surfaces at both ends of the second crushing roller 6. The first crushing knife 9 corresponds to the second crushing knife 14, and at the same time, the first crushing knife 9 and the second crushing knife 14 are correspondingly and staggeredly clamped.

[0033] During actual use, first pour the raw materials of the autoclaved thermal insulation blocks into the interior of the crusher main body 1 through the feed inlet 2, and start the motor 4. The motor 4 will drive the main gear 12 to rotate. Since the main gear 12 is clamped with the transmission gear 3, the rotation of the main gear 12 will drive the transmission gear 3 to rotate. The rotation of the main gear 12 will drive the second crushing roller 6 to rotate, and the rotation of the transmission gear 3 will drive the first crushing roller 7 to rotate. Since the diameter of the first crushing roller 7 is smaller than that of the second crushing roller 6, and at the same time the transmission gear 3 is driven by the main gear 12, the rotational speeds of the first crushing roller 7 and the second crushing roller 6 are the same. However, due to the different diameters, the linear speed of the first crushing roller 7 is greater than that of the second crushing roller 6. Therefore, the raw materials will first be ground and crushed at the gap between the first crushing roller 7 and the second crushing roller 6. Due to the presence of the spiral knife, the raw materials will be conveyed to the crushing knives at both ends, enabling the ground raw materials to be crushed for the second time. Through the two - stage crushing, the complete crushing of the raw materials is achieved. Moreover, since there are relatively deep grooves between the two groups of second crushing rollers 6 and the first crushing roller 7, and the first crushing roller 7 is located below the second crushing roller 6, the acting force of the second crushing roller 6 is obliquely downward. When large - volume raw materials are crushed, the obliquely downward force will squeeze the raw materials, causing the large - volume raw materials to break into small - volume raw materials, which is more convenient for crushing. This structure is simple, easy to operate, and is beneficial to improving its use effect.

[0034] 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.
