Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clear, the utility model will be further described in detail below in conjunction with the embodiments and drawings. Here, the schematic embodiments of the present utility model and their descriptions are used to explain the present utility model, but are not used to limit the present utility model.

Referring to Figures 1 to 6, an embodiment of the present utility model provides a toothed roller for a toothed roller crusher, which includes a roller shaft 1 and a tooth plate 2. The surface of the roller shaft 1 is provided with a plurality of dovetail grooves 3 spaced apart along the axial direction. The surface of the shaft 1 is engaged with multiple rows of tooth plates 2 along the circumferential direction through dovetail grooves 3; the tooth plate 2 includes a curved bottom plate 4 that matches the surface of the roller shaft 1, and the top surface of the curved bottom plate 4 is provided with crushing teeth 5. The bottom surface of the bottom plate 4 is provided with a double hook structure 6. The double hook structure 6 is adapted to the groove shoulder 7 formed between two adjacent dovetail grooves 3, and two adjacent tooth plates 2 in each row of tooth plates 2 The double hook structures 6 in the middle snap together into the same dovetail groove 3; in the circumferential direction, the positioning of the tooth plate 2 is achieved by the cooperation between the double hook structure 6 and the groove shoulder 7, and the cooperation between two adjacent tooth plates 2.

During implementation, the arc length of the top surface of the double hook structure 6 matches the arc length of the bottom surface of the arc bottom plate 4, and the width of the bottom surface of the arc bottom plate 4 is greater than the width of the top surface of the double hook structure 6, so that in the double hook structure The two sides of the top surface of 6 form flanges 8 .

The inner end of the roller shaft 1 is provided with a shoulder 9, and an annular baffle 11 is detachably installed on the end surface of the outer end through bolts 10. The baffle 11 cooperates with the shoulder 9 to complete the axial positioning of each row of tooth plates 2. , and the axially positioned rear baffle 11 is located within the flange 8 of a row of tooth plates 2 at the outer end, and the shaft shoulder 9 is located within the flange 8 of a row of tooth plates 2 at the inner end, so that during the crushing process, the shoulder 9 and The baffle 11 forms a protection to prevent the baffle 11 and the shaft shoulder 9 from being damaged by material collision.

In order to facilitate disassembly, the baffle 11 is a block structure composed of at least two ring segments. When a certain tooth plate 2 is seriously worn and needs to be replaced, only the corresponding ring segment can be removed instead of the entire baffle 11.
