The material groove is U-shaped.
The bearing cavity steering wheels are installed on the bearing cavity steering wheel shafts in pairs, and the bearing cavity steering wheel shafts are installed on the lifting section casing through bearing seat of the bearing cavity steering wheel.
The no-load cavity steering wheels are installed on the no-load cavity steering wheel shaft in pairs, and the no-load cavity steering wheel shaft is installed on the lifting section casing through a no-load cavity steering wheel bearing seat.
The utility model relates to a turning mechanism of scraper blade lifting machine has following technological effect:
1) the steering mechanism is provided with three groups of steering wheels, and consists of two groups of steering wheels with bearing cavities and one group of steering wheels with no-load cavities, and the steering mechanism is also provided with a U-shaped material groove. The structure solves the problem of overlarge tension when the chain is bent excessively, the guide wheel can prevent the chain from deviating, and a plurality of problems occurring when the turning mechanism of the common conveyor is applied are well solved.
2) The material groove is changed into a simple material groove by removing the partition plate in the upper turning section, so that the bearing cavity is communicated with the no-load cavity, the working personnel can conveniently observe the material running condition, and the blockage is avoided; in addition, the maintenance is convenient, and the disassembly work during the maintenance is reduced. In addition, the material groove is arranged, the material groove is the same as the running track of the double-row roller chain scraper bucket, so that the materials can be conveyed upwards, and the phenomenon that materials are blocked is avoided.

fig. 1 is a front view of the present invention.
Fig. 2 is a cross-sectional view at a in fig. 1.
Fig. 3 is a view from direction B of fig. 1.
In the figure: the device comprises a lifting section casing 1, a material groove 2, a bearing cavity steering wheel 3, a cover plate 4, a double-row roller chain scraper bucket 5, an upper horizontal section casing 6, a bearing cavity steering wheel bearing seat 7, a bearing cavity steering wheel shaft 8, a no-load cavity steering wheel bearing seat 9, a no-load cavity guide rail 11, a no-load cavity steering wheel shaft 10 and a no-load cavity steering wheel 12.
Detailed Description
As shown in fig. 1-3, a turning mechanism of a scraper lifter comprises a lifting section casing 1, wherein the right end of the lifting section casing 1 is connected with an upper horizontal section casing 6.
A U-shaped material groove 2 is formed in the lifting section casing 1, and the lower end of the U-shaped material groove 2 is connected with a bottom plate of the lifting portion in a smooth transition mode. The upper end of the U-shaped material groove 2 is connected with the bottom plate of the upper horizontal section casing 6 in a smooth transition mode to jointly form a material bearing part of the scraper lifter.
Two groups of bearing cavity steering wheels 3 are installed below the material groove 2 along the bending direction of the lifting section casing 1, and the two groups of bearing cavity steering wheels 3 are identical in structure. The bearing cavity steering wheels 3 are installed on a bearing cavity steering wheel shaft 8 in pairs, and the bearing cavity steering wheel shaft 8 is installed on the lifting section casing 1 through a bearing cavity steering wheel bearing seat 7.
A group of no-load cavity steering wheels 12 are installed above the material groove 2, the no-load cavity steering wheels 12 are installed on a no-load cavity steering wheel shaft 10 in pairs, and the no-load cavity steering wheel shaft 10 is installed on the lifting section casing 1 through a no-load cavity steering wheel bearing seat 9.
In addition, an idle cavity guide rail 11 is also arranged above the lifting section casing 1 and the upper horizontal section casing 6, and the idle cavity guide rail 11 is used for guiding the double-row roller chain scraper bucket 5 during return stroke.
The working principle and the process are as follows:
the materials are conveyed by a scraper chain bucket 5 with double rows of roller chains and enter a U-shaped material trough 2 in a lifting section shell 1 through a bearing cavity of a lifting section of a scraper lifter. The roller chains of the double-row roller chain scraper bucket 5 are meshed with the two groups of bearing cavity steering wheels 3 successively, materials are conveyed horizontally through the material grooves 2 in a lifting mode, the arrangement mode of the U-shaped material grooves is matched with the running track of the scraper chains to achieve stable transition of the material conveying direction, the conveying quantity of the materials is guaranteed, and due to the fact that the design gap is proper in the whole process, the running track of the chains is guaranteed through the two groups of guide wheels, and therefore scraping and rubbing between the scraper and the shell cannot occur.
During the return stroke, the double-row roller chain scraper bucket 5 enters the lifting section casing 1 from the upper horizontal section casing 6, and the chain of the double-row roller chain scraper bucket 5 is guided by the no-load cavity guide rail 11, so that the chain of the double-row roller chain scraper bucket 5 can be meshed with a group of no-load cavity steering wheels 12 to change the direction stably, and then enters the lifting section through the lifting section casing 1 to return. Due to the reasonable layout of the steering wheel, the U-shaped material groove and the guide rail and the accurate design of the gap between the scraper bucket and the shell, the whole turning mechanism of the scraper hoist has high conveying efficiency in the use process, has no scraping phenomenon, is totally rolling friction, and has small friction, small abrasion, low energy consumption and long service life.
