Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a crusher tooth plate fixing structure. Background Technology

[0002] A crusher is a mechanical device used to break large materials into smaller particles, widely used in mining, construction, metallurgy, and chemical industries. Currently, the toothed roller of a crusher mainly consists of a toothed plate and a toothed seat. The toothed plate is fixed or integrally formed on the toothed seat. When the toothed seat rotates, the toothed plate rotates synchronously, crushing large objects. However, because the toothed plate is fixed or integrally formed on the toothed seat, when the teeth on the toothed plate break, the entire toothed plate and toothed seat need to be replaced. This is not only difficult and time-consuming to replace, but also poses a risk of injury to workers and serious safety accidents.

[0003] To address the aforementioned technical issues, some manufacturers have implemented detachable tooth plate connections to the tooth base. Specifically, connecting holes are cast into the tooth plate, and threaded holes are drilled into the tooth base. The tooth plate is then secured to the tooth base using bolts. In this type of crusher, which operates at high speeds, the connecting bolts not only provide a secure connection but also transmit torque between the tooth plate and the tooth base. Besides the tensile force from the connection, the tooth plate is also subjected to significant shearing forces. If the connecting bolts break, the tooth plate will detach from the high-speed rotating tooth base, potentially causing damage to the equipment or even serious injury or death.

[0004] Therefore, how to design a crusher tooth plate fixing structure that is simple in structure, firmly connected and easy to disassemble is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a crusher tooth plate fixing structure, which solves the technical problem of the existing tooth plate fixing structure being not firm.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a crusher tooth plate fixing structure, wherein multiple teeth are fixed at intervals on one side of the tooth plate, including: tooth seat, first fixing block, second fixing block and locking member.

[0007] The first fixing block and the second fixing block are detachably connected to the toothed seat at intervals and define an insertion area between the first fixing block and the second fixing block; a protrusion is fixed on the other side of the toothed plate, the protrusion is inserted into the insertion area and defines a locking area between the protrusion and the second fixing block; the locking member is placed in the locking area and its two opposite sides contact the side of the protrusion and the side of the second fixing block respectively, so as to press the protrusion into contact with the first fixing block and lock the toothed plate onto the toothed seat.

[0008] The beneficial effects of this utility model are: it improves the traditional crusher tooth plate fixing structure. First, the first fixing block and the second fixing block are detachably connected to the tooth seat at intervals, and an insertion area is defined between the first fixing block and the second fixing block. Then, the protrusion fixed on the other side of the tooth plate is inserted into the insertion area, and a locking area is defined between the protrusion and the second fixing block. Since the locking block is placed in the locking area and its two opposite sides are in contact with the side of the protrusion and the side of the second fixing block respectively, the locking block can be used to squeeze the protrusion and the first fixing block into tight contact, thereby improving the firmness of the protrusion clamped between the locking block and the first fixing block and preventing the tooth plate from falling off the tooth seat.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the sides of the first fixing block and the second fixing block that are close to each other are arranged at an angle from away from the tooth seat to closer to the tooth seat and then towards the direction away from the insertion area, so that the longitudinal section of the insertion area is designed as a trapezoidal structure; the longitudinal section of the protrusion is a trapezoidal structure and the longitudinal section of the locking member is a parallelogram structure, so that the protrusion and the locking member are adapted to be disposed in the insertion area and the locking area.

[0011] The further beneficial effects of adopting the above are: firstly, the longitudinal section of the insertion area is designed as a trapezoidal structure, and then the longitudinal section of the protrusion is designed as a trapezoidal structure and the longitudinal section of the locking member is designed as a parallelogram structure. This allows the protrusion and the locking member to be appropriately configured in the insertion area and the locking area, thereby improving the firmness of the protrusion clamped between the locking member and the first fixing block and preventing the toothed plate from detaching from the toothed seat.

[0012] Furthermore, the locking member includes a first locking block and a second locking block, the first locking block and the second locking block being spaced apart within the locking area and their opposite sides respectively contacting the side of the protrusion and the side of the second fixing block.

[0013] Furthermore, the heights of the first locking block and the second locking block both increase sequentially from the direction of approaching each other to the direction of moving away from each other.

[0014] The further beneficial effect of adopting the above is that the height of the first locking block and the height of the second locking block are designed to increase sequentially from the direction of mutual approach to the direction of mutual distance. This not only facilitates the insertion of the first locking block and the second locking block into the locking area, but also gradually squeezes the protrusion into contact with the first fixing block while the first locking block and the second locking block are continuously inserted, thereby improving the firmness of the protrusion clamped between the locking member and the first fixing block and preventing the toothed plate from disengaging from the toothed seat.

[0015] Furthermore, the locking component also includes a tensioning screw and a locking nut. The first locking block is provided with a threaded hole A; the second locking block is provided with a through hole; the tensioning screw is threadedly connected to the threaded hole A and passes through the through hole; the locking nut is threadedly connected to the through end of the tensioning screw that exits the through hole.

[0016] The further beneficial effect of the above is that: first, the tensioning screw is threaded into the threaded hole A, and then the locking nut is threaded into the through end of the tensioning screw that passes through the through hole. Rotating the locking nut can reduce the distance between the first locking block and the second locking block, so that the first locking block and the second locking block are continuously inserted into the locking area, which improves the firmness of the protrusion clamped between the locking member and the first fixing block and prevents the toothed plate from disengaging from the toothed seat.

[0017] Furthermore, it also includes two fixing bolts, and both the first fixing block and the second fixing block are provided with countersunk holes; the gear seat is provided with threaded holes B respectively arranged opposite to the two countersunk holes; the two fixing bolts respectively pass through the two countersunk holes and are screwed into the corresponding threaded holes B.

[0018] Furthermore, the longitudinal section of the tooth base, the first fixing block, the second fixing block, and the tooth plate are all arc-shaped. Attached Figure Description
