[0020] 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.

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a novel open double-toothed roller crusher, comprising: a crusher body 1, a frame 2 provided on one side of the crusher body 1, and crushing rollers 3 installed on the inner wall of the frame 2. In this design, the crusher body 1, the frame 2 and the crushing rollers 3 constitute the main body of the novel open double-toothed roller crusher, and a large number of related components are provided in the main body of the novel open double-toothed roller crusher. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0022] The main model of the new open double toothed roll crusher in this design is: DL2GPX1218;

[0023] In operation: The new type of open double toothed roll crusher crushes materials through two relatively rotating toothed rolls. When the two toothed rolls rotate relative to each other, their serrations mesh together, thereby crushing or cutting the object. This working method is similar to gear meshing, but the serration structure of the double toothed roll crusher is more complex and can provide greater crushing force.

[0024] A fixed baffle 4 is welded to the top of the frame 2. An adjusting guard plate 5 is fitted onto the surface of the fixed baffle 4. A toothed plate 6 is connected to one side of the adjusting guard plate 5. A gear 7 is meshed onto the surface of the toothed plate 6. A bolt 8 is longitudinally connected through the top surface of the shaft side of the gear 7. The bottom of the bolt 8 is threaded to the transmission end of the motor 9. The bottom of the motor 9 is connected to the top of the first mounting bracket 10. The toothed plate 6 is connected through the side wall of the first mounting bracket 10. One side of the first mounting bracket 10 is connected to one side of the frame 2. The other side of the frame 2 is connected to the second mounting bracket 11. A vertical rod 12 is fixedly connected to the top of the second mounting bracket 11. A moving block 13 is slidably connected to the side wall of the vertical rod 12. The other side of the moving block 13 is connected to the outer wall of the adjusting guard plate 5.

[0025] Preferably, the adjusting guard plate 5 is a rectangular integral structure with rectangular through slots on both sides, and the shape and size of the through slots are adapted to the fixed baffle 4.

[0026] In practical use, the rectangular slots on both sides of the adjustable guard plate 5 allow it to move up and down on the fixed baffle 4 to adjust its height and shield the frame 2.

[0027] Preferably, the adjusting guard plate 5, the toothed plate 6, the gear 7, the bolt 8 and the motor 9 form a meshing connection structure.

[0028] In actual use, start the motor 9 to make it start to rotate. When the motor 9 rotates, the gear 7 fixed at its transmission end rotates together. The rotation of the gear 7 drives the meshing toothed plate 6 to move upward, which in turn drives the connected adjusting guard plate 5 to move on the fixed baffle 4.

[0029] Preferably, the gear 7, bolt 8, and motor 9 form a threaded connection structure.

[0030] In practical use, the two can be disassembled and maintained by unscrewing the bolt 8 that is fixed between the gear 7 and the motor 9.

[0031] Preferably, a rectangular through groove is formed on the side wall surface of the first mounting bracket 10, and the shape and size of the through groove are adapted to the toothed plate 6.

[0032] In practical use, the through slot on one side of the first mounting bracket 10 allows the toothed plate 6 to move up and down on it without being affected.

[0033] Preferably, the adjusting guard plate 5, the vertical rod 12 and the moving block 13 form a sliding connection structure, and a rectangular sliding groove is opened on the side wall of the vertical rod 12, and the shape and size of the sliding groove are adapted to the moving block 13.

[0034] In actual use, while the adjusting guard plate 5 moves on the fixed baffle 4, the moving block 13 on its other side surface slides within the vertical rod 12 on the second mounting bracket 11 fixed on the other side of the frame 2, thereby maintaining the stable movement of the adjusting guard plate 5.

[0035] Working principle: When using the new type of open double toothed roller crusher to crush materials, the motor 9 is started to rotate according to the size of the material to be crushed and the quantity of material to be fed. When the motor 9 rotates, the gear 7 fixed at its transmission end rotates together. The rotation of the gear 7 drives the meshing toothed plate 6 to move upward, which in turn drives the connected adjusting guard plate 5 to move on the fixed baffle 4. While the adjusting guard plate 5 moves on the fixed baffle 4, the moving block 13 on its other side surface slides in the vertical rod 12 on the second mounting frame 11 fixed on the other side of the frame 2, thereby maintaining the stable movement of the adjusting guard plate 5, blocking the bottom frame 2 and the crushing roller 3 inside it. At the same time, the material being fed is also blocked by the rising adjusting guard plate 5, preventing it from slipping off the top of the frame 2 and affecting the efficiency of the crushing work.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
