Description
Technical Field
The utility model relates to a mud scraping structure specifically is a gyration mud scraping plate structure for excavator.
Background
The problem that soil (or stones) are easily accumulated at the position of a gap between the excavator rotary platform and the lower frame and are difficult to clean is solved, when the accumulated soil is too much, the rotary action of the excavator can rub and scrape the rotary support lubrication pipeline at the position, and the pipeline is broken by abrasion.
In conclusion, how to remove the soil in the gap between the rotary platform and the lower frame becomes a problem which needs to be solved urgently by researchers of the company,
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to remove soil at the gap between the rotary platform and the lower frame;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a rotary scraper structure for a digging machine, which comprises a mounting plate; the mounting plate is horizontally and fixedly mounted on the bottom end face of the slewing bearing, the slewing bearing is sleeved on the slewing platform, the other end of the mounting plate is welded with a vertical plate which is vertically arranged, the bottom of the vertical plate is provided with a mud scraper which is vertically arranged, and the bottom edge of the mud scraper is in contact with the upper end face of the lower frame;
the rotary support is sleeved on the rotary platform, so that the rotary platform drives the rotary support to rotate when rotating, a horizontal mounting plate is fixed at the bottom of the rotary support, a vertical plate is welded at the other end of the mounting plate, a mud scraper is mounted at the bottom of the vertical plate, and the mud scraper is driven to do circular motion when the rotary platform rotates; as the bottom edge of the mud scraping plate is contacted with the upper end face of the lower frame, mud arranged on the upper surface of the lower frame can be rotated and thrown out, and the mud scraping effect is achieved.
In order to explain the connection relationship between the mounting plate and the slewing bearing, the utility model adopts the mounting plate which is provided with a plurality of mounting holes, and the bolts pass through the mounting holes and are fixedly connected with the through holes of the slewing bearing;
because the slewing bearing is provided with the through hole, the through hole mounting bolts on the slewing bearing are used for superposition mounting, and additional punching is not needed.
In order to ensure the connecting strength of the vertical plate and the mounting plate, the utility model adopts the vertical welding of the welding part of the vertical plate and the mounting plate with the rib plate;
the rib plate plays a role of a reinforcing rib, and the connection strength of the vertical plate and the mounting plate is ensured.
Because the mud scraping plate belongs to a quick-wear part in the mud scraping process, how to realize the replacement of the worn mud scraping plate, the bottom of the vertical plate is detachably connected with the mud scraping plate through a second bolt;
the detachable connection of the mud scraping plate and the vertical plate is realized through the second bolt, so that the subsequent wear-out can be conveniently replaced.
The utility model has the advantages that: the utility model relates to a rotary mud scraper structure for excavator, a mud scraper is arranged at the gap between a rotary platform and a lower frame, and the mud scraper is arranged on a rotary support through a vertical plate and a mounting plate; when the rotary platform drives the rotary support to rotate, the mud scraping plate is driven to rotate relative to the lower frame, soil on the upper end face of the lower frame is rotated and thrown out, and the mud scraping effect is achieved.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a detail view of the mounting plate of the present invention;
in the figure: 1-mounting plate, 2-slewing bearing, 3-slewing platform, 4-vertical plate, 5-mud scraper, 6-lower frame, 7-bolt, 8-rib plate and 9-second bolt.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the utility model relates to a rotary scraper structure for excavator, comprising a mounting plate 1; the mounting plate 1 is horizontally and fixedly mounted on the bottom end face of the slewing bearing 2, the slewing bearing 2 is sleeved on the slewing platform 3, the other end of the mounting plate 1 is welded with a vertical plate 4 which is vertically arranged, the bottom of the vertical plate 4 is provided with a mud scraper 5 which is vertically arranged, and the bottom edge of the mud scraper 5 is in contact with the upper end face of the lower frame 6;
the rotary support is sleeved on the rotary platform, so that the rotary platform drives the rotary support to rotate when rotating, a horizontal mounting plate is fixed at the bottom of the rotary support, a vertical plate is welded at the other end of the mounting plate, a mud scraper is mounted at the bottom of the vertical plate, and the mud scraper is driven to do circular motion when the rotary platform rotates; as the bottom edge of the mud scraping plate is contacted with the upper end face of the lower frame, mud arranged on the upper surface of the lower frame can be rotated and thrown out, and the mud scraping effect is achieved.
As shown in fig. 2, in order to illustrate the connection relationship between the mounting plate and the slewing bearing, the mounting plate 1 of the present invention is provided with a plurality of mounting holes, and the bolts 7 pass through the mounting holes to be fixedly connected with the through holes of the slewing bearing 2;
because the slewing bearing is provided with the through hole, the through hole mounting bolts on the slewing bearing are used for superposition mounting, and additional punching is not needed.
