Abstract

The utility model relates to a tooth roller of a tooth roller crushing machine of mine equipment, in particular to a multi-section combined tooth roller. The multi-section combined tooth roller is structurally characterized in that two or more tooth roller sections are arranged on a main shaft in a combined manner, all tooth roller sections have the same structure, two ends of a separation sleeve are provided with bow-shaped body seats, four bow-shaped bodies are arranged on the bow-shaped body seats at two ends to be combined into a circular tooth roller surface, casting teeth are uniformly distributed on the outer surface of the bow-shaped bodies in lines, and in addition, each line of casting teeth of each tooth roller section in the axial direction are mutually staggered and ranged after the combination. The multi-section combined tooth roller has the characteristics that the multi-section combination is adopted, and the dismounting and the maintenance are convenient; the torsion torque can be effectively transferred between the main shaft and the bow-shaped body seats; two tooth roller sections or more than two tooth roller sections are combined into one tooth roller, the length of the whole tooth roller is effectively lengthened, the material passing quantity is increased, and the crushing quantity of the crushing machine in unit time is improved; and meanwhile, the independent block and element casting, the subsection assembly and the multi-section combination are adopted, the casting problem of a long tooth roller is effectively solved, the casting production efficiency is higher, and the problem of the rough tooth roller casting process is solved.

Description

A kind of multi-section combined discaling roll

Technical field

The utility model relates to the discaling roll of mining equiment rod-toothed crusher, relates in particular to a kind of multi-section combined discaling roll.

Background technology

At present, the discaling roll on the toothed roll crusher is owing to use wearing and tearing to need the discaling roll that often more renew, and discaling roll mainly relies on the new material solution in the problem of intensity, aspect such as wear-resisting and shock-resistant at present, and cost is higher; The roller tooth distributes along the parallel distribution of beaming roller or spiral, in shattering process, also rectangular material can occur, and particle size after cracking is inhomogeneous, granularity problem such as exceed standard.Existing typing discaling roll is can't the simultaneous adaptation ore size big, impulsive force is big and crushing is big, and can also satisfy discaling roll intensity high, wear-resistant, shock-resistant, simple in structure, be prone to produce functional requirements such as maintenance, cost be low.

Summary of the invention

The goal of the invention of the utility model is to provide a kind of and can addresses the above problem, and to improve intensity, wear-resistant, shock resistance, long service life, to be prone to produce maintenance, adapts to a kind of multi-section combined discaling roll of producing from the improvement of discaling roll structure.

The technical scheme of the utility model is such: a kind of multi-section combined discaling roll comprises main shaft 1, the first discaling roll section 2, the second discaling roll section 3; The structure of the first discaling roll section 2 is that spacer sleeve 6 is housed on main shaft 1, and toxoplasm seat 4 is equipped with at the two ends of spacer sleeve 6 on the main shaft 1; Evenly by the row casting tooth 7 that distributes, the radial section of toxoplasm 5 is a circular arc to toxoplasm 5 outer surfaces, and arc length is that 1/4, four toxoplasm 5 of whole circumference is contained in and is combined into a round tooth roll surface on the two ends toxoplasm seat 4; The structure of the structure of the second discaling roll section 3 and the first discaling roll section 2 is identical; The first discaling roll section 2 and the second discaling roll section 3 are contained on the main shaft 1, and caging bolt 8 stationary positioned are equipped with at two ends, and the first discaling roll section 2 every row casting tooth 7 vertically staggers each other with the second discaling roll section, 3 every row casting teeth 7 and arranges installation.

The characteristics of the utility model are simple in structure, and are reasonable in design, and multisection type combination is dismantled easy to maintenancely, and cost is low; Be connected reliably between toxoplasm seat and the toxoplasm, can effectively transmit moment of torsion between main shaft and the toxoplasm seat; Two toxoplasm seats, four toxoplasms, a spacer sleeve are combined into a discaling roll section on main shaft; Two discaling roll sections or two above discaling roll sections are combined into a discaling roll; The whole discaling roll length that effectively extended has increased the punishment in advance amount, has improved the crushing of disintegrating machine unit interval; Simultaneously, piecemeal, bulk-breaking casting, the segmentation assembling, the multistage combination has solved a long discaling roll casting difficult problem effectively, and casting production efficiency is higher; Toxoplasm has solved a bastard roller casting technique difficult problem again in circumferential polylith combination.

The specific embodiment

Like Fig. 1, shown in 2, a kind of multi-section combined discaling roll comprises main shaft 1, the first discaling roll section 2, the second discaling roll section 3; The structure of the first discaling roll section 2 is that spacer sleeve 6 is housed on main shaft 1, and toxoplasm seat 4 is equipped with at the two ends of spacer sleeve 6 on the main shaft 1; Evenly by the row casting tooth 7 that distributes, the radial section of toxoplasm 5 is a circular arc to toxoplasm 5 outer surfaces, and arc length is that 1/4, four toxoplasm 5 of whole circumference is contained on the toxoplasm seat 4 at two ends and is combined into a round tooth roll surface; The structure of the structure of the second discaling roll section 3 and the first discaling roll section 2 is identical; The first discaling roll section and the second discaling roll section 3 are contained on the main shaft 1, and caging bolt 8 stationary positioned are equipped with at two ends, and the first discaling roll section 2 every row casting tooth 7 vertically staggers each other with the second discaling roll section, 3 every row casting teeth 7 and arranges installation.

As shown in Figure 3; A kind of multi-section combined discaling roll of forming by three sections discaling roll sections; Three the i.e. first discaling roll section 2, the second discaling roll section 3 and the 3rd discaling roll sections 9 are housed on main shaft 1; And axially caging bolt 8 stationary positioned are equipped with at two ends, and every row casting tooth 7 that the first discaling roll section 2, the second discaling roll section 3 and the 3rd discaling roll section 9 distribute vertically staggers each other and arranges installation.

During work, can effectively transmit moment of torsion between main shaft and the 1 toxoplasm seat 4.Be connected reliably between toxoplasm seat 4 and the toxoplasm 5, dismounting and change is convenient; Two toxoplasm seats 4, four toxoplasms 5, a spacer sleeve 6 are combined into a discaling roll section on main shaft 1; Can adopt two above discaling roll sections to be combined into discaling roll as required; The whole discaling roll length that effectively extended has increased the punishment in advance amount, has improved the crushing of disintegrating machine unit interval; Simultaneously, piecemeal, bulk-breaking casting, the segmentation assembling, the multistage combination has solved a long discaling roll casting difficult problem effectively, and casting production efficiency is higher; Toxoplasm 5 has solved a bastard roller casting technique difficult problem again in circumferential polylith combination.
