[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The utility model provides a technical solution: an adjustable material opening mechanism for a roller crusher, comprising a fixed roller 1 and a movable roller assembly rotatably mounted on a crusher frame, the movable roller assembly comprising an adjusting disk 2 rotatably arranged on the crusher frame, a movable roller 21 rotatably arranged on the adjusting disk 2 for cooperating with the fixed roller 1 to crush materials, evenly distributed latch teeth 3 are arranged at the lower end of the peripheral side surface of the adjusting disk 2, and a tooth plate 4 meshing with the latch teeth 3 is horizontally slidably arranged on the crusher frame, an adjusting member for adjusting the tooth plate 4 is arranged at one end of the crusher frame corresponding to the tooth plate 4, the adjusting member adjusts the position of the tooth plate 4, the tooth plate 4 drives the adjusting disk 2 to rotate through the latch teeth 3, and the movable roller 21 is driven to rotate when the adjusting disk 2 rotates, thereby adjusting the width of the discharge port between the movable roller 21 and the fixed roller 1.

[0020] A positioning piece is provided at the other end of the crusher frame corresponding to the tooth plate 4, and the positioning piece includes a threaded seat 6 installed on the crusher frame, and a positioning screw 61 is threadedly connected to the screw hole of the threaded seat 6. One end of the positioning screw 61 is in contact with the tooth plate 4. After the tooth plate 4 is adjusted, the positioning screw 61 is rotated and made to contact with the tooth plate 4 to prevent the tooth plate 4 from moving under the action of the elastic member 51 during operation.

[0021] Furthermore, a guide roller 22 is rotatably provided on the adjusting disk 2. The guide roller 22 is located on the upper side of the movable roller 21 away from the fixed roller 1, and when the movable roller 21 rotates, it can drive the guide roller 22 to rotate, so as to facilitate the transportation of materials between the movable roller 21 and the fixed roller 1.

[0022] Furthermore, the diameter of the fixed roller 1 is larger than the diameter of the movable roller 21, and the center axis of the fixed roller 1 is higher than the center axis of the movable roller 21, so that the fixed roller 1 is higher than the movable roller 21 and the diameter of the fixed roller 1 is larger than the diameter of the movable roller 21, which is convenient for conveying and crushing materials.

[0023] Furthermore, the adjusting member includes a hydraulic cylinder 5, and an elastic member connected to the tooth plate 4 is provided at the telescopic end of the hydraulic cylinder 5. The elastic member is a spring with a telescopic rod inside, which controls the extension and retraction of the hydraulic cylinder 5. The hydraulic cylinder 5 drives the tooth plate 4 to move through the elastic member 51. During the movement of the tooth plate 4, the adjusting disk 2 is driven to rotate through the latch teeth 3. When the adjusting disk 2 rotates, the movable roller 21 is driven to rotate, thereby adjusting the distance between the movable roller 21 and the fixed roller 1, that is, adjusting the material port, such as Figure 3 and Figure 4 shown.

[0024] When using:

[0025] The external driving device is connected to the fixed roller 1 and the movable roller 21 respectively, and the fixed roller 1 and the movable roller 21 rotate to crush the material;

[0026] Adjusting the material opening means adjusting the distance between the fixed roller 1 and the movable roller 21. The adjustment method is as follows:

[0027] The hydraulic cylinder 5 is controlled to extend and retract, and the hydraulic cylinder 5 drives the tooth plate 4 to move through the elastic member 51. During the movement of the tooth plate 4, the adjusting disk 2 is driven to rotate through the latch teeth 3. When the adjusting disk 2 rotates, the movable roller 21 is driven to rotate, thereby adjusting the distance between the movable roller 21 and the fixed roller 1, that is, adjusting the material opening, such as Figure 3 and Figure 4 As shown;

[0028] After the adjustment is completed, the positioning screw 61 is rotated to make the positioning screw 61 contact with the tooth plate 4 to prevent the tooth plate 4 from moving under the action of the elastic member 51 during operation.

[0029] In addition, when the position of the tooth plate 4 does not change, the deformation of the elastic member 51 can be controlled by adjusting the extension and contraction amount of the hydraulic cylinder 5 and the length of the positioning screw 61, thereby adjusting the preload force of the elastic member 51 and changing the crushing force of the crusher.

[0030] The utility model can adjust the position of the movable roller 21 by rotating, so as to adjust the width of the discharge port between the movable roller 21 and the fixed roller 1, and can accurately adjust the width of the discharge port by controlling the rotation angle of the adjustment disk 2, so as to improve the uniformity of the material after crushing, and the operation is simple and convenient to use.
