However, the grinding discs used in existing bamboo pulp pulping machines will form knot-like shapes between the teeth in the crushing zone during operation due to the enlarged wood chips and fiber bundles generated during the crushing, which increases the resistance of the wood chips entering the grinding disc area in the later stage and increases the problem of later power consumption. Utility Model Content

[0003] The utility model aims to provide a grinding disc for a bamboo pulp refiner, which is convenient for operators to manually clean the knotty wood chips and fiber bundles in the grinding and crushing area.

[0004] To achieve the above-mentioned purpose, a grinding plate for a bamboo pulp refiner is provided, comprising a crushing zone, wherein crushing teeth are evenly arranged at the bottom of the crushing zone, a grinding plate zone 1 is arranged on the outside of the crushing zone, and grinding teeth 1 are evenly arranged at the bottom of the grinding plate zone 1, a grinding plate zone 2 is arranged on the outside of the grinding plate zone 1, and grinding teeth 2 are evenly arranged at the bottom of the grinding plate zone 2, fixed screws are arranged on both sides of the top of the grinding plate zone 1, the outer sides of the two groups of the fixed screws are threadedly penetrated and sleeved with internal threaded sleeve blocks, the bottoms of the two groups of the internal threaded sleeve blocks are jointly provided with an annular connecting plate, the bottoms of the two groups of the annular connecting plates are evenly provided with cleaning push blocks, and the cleaning push blocks penetrate into the interior of the crushing zone and cooperate with the crushing teeth to facilitate the cleaning function of the internal nodules of the grinding plate.

[0005] According to the grinding disc for a bamboo pulp refiner, through openings are evenly opened on one side of the crushing zone away from the crushing teeth, and the through openings cooperate with the cleaning push block to facilitate the removal and cleaning function of the cleaning push block.

[0006] According to the bamboo pulp refiner grinding disc, the outer parts of the two groups of internal thread sleeves are both provided with annular limit slip rings, and the two groups of external close sides of the annular limit slip rings are both provided with guide sliders, and the guide sliders are connected to the annular connecting plate, so as to facilitate the later realization of the internal thread sleeve fixed rotation function.

[0007] According to the grinding disc for a bamboo pulp refiner, the spacing between the multiple groups of grinding teeth one is greater than the spacing between the multiple groups of grinding teeth two, which is convenient for improving the compactness of the later bamboo pulp refining.

[0008] The above scheme has the beneficial effect: through the mutual cooperation of the fixed screw, the internal threaded sleeve block, the annular connecting plate and the cleaning push block, the uniform pushing and cleaning work of the knotted materials inside the crushing area can be achieved, so as to reduce the resistance of the wood chips entering the grinding area one and the grinding area two in the later stage, reduce the problem of power consumption, and do not require the operator to manually clean the internal spacing of multiple groups of crushing teeth, thereby improving the convenience and flexibility of the later cleaning.

[0009] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
