Further, each row of the holes is at least provided with three holes, and each hole is uniformly distributed on the outer roll shaft.
Further, the cross section of the opening along the radial direction of the outer roll shaft is trapezoid.
Further, both ends of the inner pin are respectively provided with an outer pin.
Further, the diameter of the inner roll shaft is equal to the inner diameter of the outer roll shaft.
Further, the tool bit is conical, and the tool bit is with trompil shape looks adaptation, and the tool bit includes interconnect's interior tool bit and outer tool bit, and outer tool bit lower part is equipped with ring magnet.
Further, the top end of the outer cutter head is in a spike shape or a saw tooth shape.
Further, the inner cutter head and the outer cutter head are mutually inserted.
Further, the outer cutter head is made of high-strength steel.
The beneficial effects of the invention are as follows: according to the invention, the roll shaft crusher is divided into the inner roll shaft and the outer roll shaft, the cutter head penetrates out of the opening of the outer roll shaft, the cutter head is fixed by inserting the inner roll shaft into the outer roll shaft, the inner roll shaft and the outer roll shaft are fixed by the outer column pin, even if the cutter head vibrates violently in the working process, the whole cutter head is fixed safely and reliably and cannot loosen, the cutter head is prevented from falling off and colliding with other cutter heads due to the loosening of the cutter head, the service life of the cutter head is greatly prolonged, and the maintenance period of the roll shaft crusher is prolonged; the holes are uniformly distributed on the outer roll shaft, so that the crushing uniformity is ensured; the design of the cross section shape of the opening ensures that the cutter head is well clamped in the opening under the action of the inner roller; the outer pin further ensures that the inner pin cannot fall off due to vibration in the working process, and is convenient to observe and adjust; the diameter of the inner roll shaft is equal to the inner diameter of the outer roll shaft, so that the integral linkage of the roll shaft pulverizer in the pulverizing process is ensured.
The cutter head is divided into two parts, and only the outer cutter head is replaced when the cutter head is replaced, so that the use amount of high-strength steel of the cutter head is greatly saved, and the cost is saved; the lower part of the outer cutter head is provided with a ring magnet, so that on one hand, the position of the cutter head adsorbed on the outer roll shaft is ensured to be relatively fixed during installation, and the cutter head is convenient to insert into the inner roll shaft; on the other hand, the outer cutter head is magnetized, and iron substances are adsorbed in the crushing process; the top end of the outer cutter head is in a spike shape or a saw tooth shape, and the outer cutter head are matched with each other, so that the crushing effect is better.
The invention has novel structure and convenient operation and maintenance, avoids the phenomenon of 'beating the cutter head' in crushing, and greatly improves the working efficiency.
