The annular tooth plates and the toothed roller shaft are connected by the through key and the keyway. This utility model eliminates the need for regular bolt tightening, reduces maintenance, and increases the service life.

[0004] Since the material feed distribution on the tooth plate is often difficult to achieve absolutely uniformity, and the force applied to different parts of the tooth roller during rotation is different, the tooth plate is prone to uneven local wear, and the existing tooth plate cannot be partially replaced. Summary of the Invention

[0006] In order to solve the above problems, the utility model provides a wear-resistant tooth plate of a double-toothed roller crusher, including a rotor, a plurality of tooth plates are equidistantly sleeved on the rotor, and the tooth plate is composed of two symmetrical semicircular ring designs and spliced ​​together, and a plurality of grooves are equidistantly carved in an annular manner on the side ends of the tooth plate, and the tooth plate is fixedly connected to a telescopic block at one end away from the groove, and the movable end of the telescopic block is engaged with the adjacent slot, and the two semicircular tooth plates are fixedly connected to a connecting block at one end close to each other, a screw hole is opened on the connecting block, and the two corresponding connecting blocks overlap and are fixed by a first bolt thread, and a plurality of limit blocks are fixedly connected to the inner wall of the tooth plate at an annular distance, and a circular groove corresponding to the limit block is opened on the surface of the rotor, and the limit block is engaged with the circular groove, the fixed end of the telescopic block away from the movable end is made of magnetic material, and the movable end of the telescopic block is fixedly connected to a magnetic block near the magnetic material, and a spring is fixedly connected between the magnetic material and the magnetic block, and the two adjacent telescopic block brackets are fixedly connected to a connecting rod.

[0007] In the tooth plate of the double-toothed roller crusher, by designing the tooth plate to be two semicircular spliced ​​structures and cooperating with telescopic blocks, the tooth plate with severe wear can be selectively removed according to the wear condition to achieve the effect of partial replacement.

[0008] As a further improvement of the present application, a scraping tooth is provided on the connecting rod between two adjacent telescopic blocks through a perforated sleeve, and the scraping tooth is engaged with the tooth groove.

[0009] As a further improvement of the present application, the scraping teeth are designed with an oblique angle, and the scraping tooth surface is coated with a lubricating layer.

[0010] As a further improvement of the present application, a support plate is fixedly connected to the outer wall of the crusher, and two semicircular tooth plates are fixed on the support plate, and the connecting rods close to one end are threadedly connected through a connecting head, and the connecting head is composed of two bolt parts, and the two bolt parts are rotatably connected through a bearing in the middle.

Then, the first bolt can be turned to disassemble the two semicircular tooth plates and pull the limit block out of the circular groove, so that the group of tooth plates with severe wear can be removed for replacement. If multiple continuous tooth plates need to be replaced, the telescopic block can remain unchanged, the telescopic block can be inserted into the slot, and multiple continuous tooth plates can be spliced ​​together. At this time, you only need to remove the first bolt, and multiple continuous tooth plates can be removed at the same time, which is quick and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1-4The invention shows a wear-resistant tooth plate of a double-toothed roller crusher, comprising a rotor 1, on which a plurality of tooth plates 3 are equidistantly sleeved, and the tooth plates 3 are composed of two symmetrical semicircular rings. A plurality of slots 4 are equidistantly cut in a circular manner on the side ends of the tooth plates 3. A telescopic block 5 is fixedly connected to one end of the tooth plates 3 away from the slots 4, and the movable end of the telescopic block 5 is engaged with the adjacent slots 4. The two semicircular tooth plates 3 are fixedly connected to a connecting block 8 at one end close to each other. The connecting block 8 is provided with a screw hole 9. The two corresponding connecting blocks 8 are overlapped and fixed by a first bolt 10. The inner wall of the tooth plate 3 is fixedly connected in a circular manner at equal distances. It is connected to multiple limit blocks 7, and circular grooves 2 corresponding to the limit blocks 7 are opened on the surface of the rotor 1, and the limit blocks 7 are engaged with the circular grooves 2. The fixed end of the telescopic block 5 away from the movable end is made of magnetic material, and the movable end of the telescopic block 5 is fixedly connected to a magnetic block 11 near the end of the magnetic material, and a spring is fixedly connected between the magnetic material and the magnetic block 11. The two adjacent telescopic block 5 brackets are fixedly connected with a connecting rod 6, and the connecting rod 6 at one end of the two semicircular tooth plates 3 close to each other is threadedly connected by a connecting head 13, and the connecting head 13 is composed of two bolt parts, and the two bolt parts are rotatably connected through a bearing in the middle.

[0025] Working principle: When the tooth plate 3 is seriously worn and needs to be replaced, the wear condition of the tooth plate 3 can be observed. The tooth plate 3 with serious wear can be replaced, and the connecting rod 6 can be held by hand to slide the movable ends of multiple telescopic blocks 5 on the same semicircular tooth plate 3 at the same time, so that the magnetic block 11 is attracted to the magnetic material in the telescopic block 5, and the telescopic block 5 can be pulled out from the slot 4, and the two adjacent tooth plates 3 arranged radially can be disconnected. Then, the first bolt 10 can be tightened to disassemble the two semicircular tooth plates 3 and pull the limit block 7 out of the circular groove 2, so that the group of tooth plates 3 with serious wear can be removed and replaced. If multiple consecutive tooth plates 3 need to be replaced, the telescopic block 5 can remain unchanged, the telescopic block 5 can be inserted into the slot 4, and multiple consecutive tooth plates 3 can be spliced ​​together. At this time, you only need to remove the first bolt 10, and multiple consecutive tooth plates 3 can be removed at the same time, which is quick and convenient.

[0026] By designing the tooth plate 3 to be formed by splicing two semicircular shapes and cooperating with the telescopic block 5, the tooth plate 3 with severe wear can be selectively removed according to the wear condition, thereby achieving the effect of partial replacement.

[0027] The second implementation method:

[0028] Figure 5-6 The rotor 1 is shown to be installed in the crusher. A scraper 12 is provided on the connecting rod 6 between the two adjacent telescopic blocks 5 through a through-hole 14, and the scraper 12 is engaged with the tooth groove. The scraper 12 is designed at an angle, and the surface of the scraper 12 is coated with a lubricating layer. The scraper 12 is made of magnetic material at the angle and is attracted to the tooth plate 3. The scraper 12 is designed in two halves, and the scraper 12 is sleeved on the surface of the connecting rod 6 and fixed by screws.

[0029] Working principle: When crushing materials with high viscosity, the materials are easy to stick to the teeth of the tooth plate 3. At this time, you can hold the connecting rod 6 and slide the movable end of the telescopic block 5 toward the tooth groove, driving the scraper 12 stuck in the tooth groove to move synchronously, and the materials stuck to the side wall of the tooth groove can be scraped off. You can also press the scraper 12 to pry it upwards to remove the materials that fall on the scraper 12. When not in use, it is locked with the tooth groove and fixed by attraction. The tooth plate 3 will not shake during rotation and affect the use of the crusher. If the scraper 12 is severely worn during long-term use and needs to be replaced, the screws can be removed and the scraper 12 can be split into two halves for replacement.

[0030] By sliding, pressing and prying the telescopic block 5 , the scraping teeth 12 can scrape off the sticky matter in the tooth groove.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
