The utility model relates to a kind of rolling shaft structure of sieving approach mix and blend scraper bowl, comprise roller bearing, axis along roller bearing is installed with n group projection (2), the quantity often organizing projection is m, each group of projection is arranged on the same sagittal plane of roller bearing, the position interlaced arrangement of adjacent projections group, described roller bearing is by the left axle (1a) in specular and right axle (1b) is affixed forms.The quantity of described roller bearing upper protruding block n is 32 groups, and the quantity m often organizing projection is 3.The junction of described left axle and right axle is provided with left shaft retaining ring (3) and right shaft retaining ring (4), and described left shaft retaining ring is fixedly connected with by bolt (5) with right shaft retaining ring.The utility model is after long-term use when the sieving approach effect of roller bearing reduces or when there are other faults, can realize maintenance fast or change, saved maintenance cost, improve operating efficiency as long as left axle and right axle are split.
Description
Technical field
The utility model relates to soil remediation equipment, specifically refers to, a kind of rolling shaft structure structure of sieving approach mix and blend scraper bowl.
Background technology
Along with urban industrial structure adjustment and the change of space layout, a large amount of industrial sites changes purposes redevelopment utilization, brings serious industrial sites pollution problem thus.According in April, 2014 Chinese Ministry of Environmental Protection and territory portion combine " the national Soil Pollution Investigation publication " of issue, whole nation soil environment situation totally allows of no optimist, some areas soil pollution is heavier, and arable soil environmental quality causes anxiety, industry and mining discarded ground soil environment outstanding problem.The human activity such as industry and mining, agricultural and Environmental Background Values of Soils height are the main causes causing soil pollution or exceed standard.Soil total exceeding standard rate in the whole nation is 16.1%, and wherein slightly, slightly, moderate and serious pollution point position ratio be respectively 11.2%, 2.3%, 1.5% and 1.1%.Pollution type is based on inorganic type, and organic type takes second place, and compound pollution proportion is less, and an inorganic pollution figure place that exceeds standard accounts for 82.8% of all super punctuation bits.(as the Yangtze River Delta Area) soil in south China area has the feature of high viscosity, high-moisture percentage, and the common difficulty run in project treatment has soil to be difficult to fragmentation, easily bonds, cannot by problems such as medicament and the abundant haptoreactions of soil.For the problems referred to above, the applicant have developed a kind of for soil remediation sieving approach mix and blend scraper bowl, can realize carrying out soil sieving approach and mix and blend simultaneously, but in use find the increasing along with soil treatment amount, there is the situation of bending in roller bearing, have impact on the sieving approach effect to soil, due to roller bearing be fixed on scraper bowl both sides bearing block between, maintain and replace gets up to compare wastes time and energy.
Utility model content
Technical problem to be solved in the utility model is the rolling shaft structure providing a kind of sieving approach mix and blend scraper bowl, sound construction and be convenient to dismounting.
The technical scheme that the utility model solves the problem is as follows:
A rolling shaft structure for sieving approach mix and blend scraper bowl, comprises roller bearing, and the axis along roller bearing is installed with n group projection, the quantity often organizing projection is m, each group of projection is arranged on the same sagittal plane of roller bearing, and the position interlaced arrangement of adjacent projections group, is characterized in that:
Described roller bearing is by the left axle in specular and right axle is affixed forms.
Further improvement is, the quantity of described roller bearing upper protruding block n is 32 groups, and the quantity m often organizing projection is 3.
As preferably, projection adjacent between two in described each group of bumps become the angle of central angle to be respectively 150 °, 149 ° and 61 °, the angle that two adjacent group of bumps stagger mutually is 90 °.
Further again, the junction of described left axle and right axle is provided with left shaft retaining ring and right shaft retaining ring, and described left shaft retaining ring and right shaft retaining ring are bolted to connection.
Compared with prior art, the beneficial effects of the utility model are:
Roller bearing of the present utility model is formed by fixedly connecting by left axle and right axle, because roller bearing is no longer an overall structure, in the middle of use, not easily occurs diastrophic situation; After long-term use when the sieving approach effect of roller bearing reduces or when there are other faults, can realize maintenance fast or change, saved maintenance cost, improve operating efficiency as long as left axle and right axle are split.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail; the restriction of described embodiment not to utility model protection scope; obviously; those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection domain of the present utility model.
Shown in composition graphs 1 to Fig. 5, a kind of rolling shaft structure of sieving approach mix and blend scraper bowl, comprise roller bearing, axis along roller bearing is installed with n group projection 2, the quantity often organizing projection is m, each group of projection is arranged on the same sagittal plane of roller bearing, the position interlaced arrangement of adjacent projections group, and described roller bearing is by the left axle 1a in specular and right axle 1b is affixed forms.
Preferably, the quantity of described roller bearing upper protruding block n is 32 groups, and the quantity m often organizing projection is 3.
Projection adjacent between two in described each group of bumps become the angle of central angle to be respectively 150 °, 149 ° and 61 °, the angle that two adjacent group of bumps stagger mutually is 90 °.
As one of the connected mode of left axle and right axle, the junction of described left axle and right axle is provided with left shaft retaining ring 3 and right shaft retaining ring 4, and described left shaft retaining ring is fixedly connected with by bolt 5 with right shaft retaining ring.
Roller bearing of the present utility model is formed by fixedly connecting by left axle and right axle, because roller bearing is no longer an overall structure, in the middle of use, not easily occurs diastrophic situation; After long-term use when the sieving approach effect of roller bearing reduces or when there are other faults, can realize maintenance fast or change, saved maintenance cost, improve operating efficiency as long as left axle and right axle are split.
