The excavator mud scraping device has the advantages that through the self characteristic of rotation of the excavator body during operation of the excavator, once mud and sand enter the upper end face of the chassis, the mud and sand are scraped outwards by the scraping leather and cannot be deposited on the periphery of the turntable, a series of problems (friction of the end face of a vehicle body, damage of an oil pipe and reduction of related hydraulic system efficiency due to increase of rotating load) caused by deposition of the mud and sand on the periphery of the turntable are solved, the service lives of related parts of the excavator are prolonged, a driver is liberated from heavy cleaning operation, and the operation efficiency of a vehicle is improved.
Description
Technical Field
The utility model relates to a machinery excavates technical field, specifically is an excavator mud scraping device.
Background
The excavator is an indispensable important excavating, producing and loading device in iron ore mining, and because a large amount of pond sludge exists in an iron ore mining field, when the excavator is used for excavating and loading, the pond sludge is wrapped by the stone slag and deposited in a groove-shaped space formed by the upper end surface of an excavator chassis, the lower end surface of a machine body and a slewing bearing, so that the following problems are caused:
1) the lower end surface of the body, the rotary table and the deposited soil and stone slag are subjected to vibration friction, and the generated friction resistance enables the hydraulic power system to generate additional load, so that the service life of related parts and the operation efficiency of the vehicle are reduced;
2) when in use, the friction damage of the lower end surface part of the vehicle body and the oil pipe outside the turntable is easily and directly caused;
3) after the deposited clay and the sand stone are hardened, the clay and the sand stone are very hard, difficult to clean and high in labor intensity, and the operation efficiency of the vehicle is influenced.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides a not enough to prior art, the utility model provides an excavator mud scraper has solved prior art, terminal surface under the fuselage, the earth stone sediment vibration friction of carousel and siltation, the frictional resistance who produces makes hydraulic power system produce additional load, the life and the vehicle operation efficiency of relevant spare part have been reduced, during the use, terminal surface part under the fuselage is directly caused easily, carousel outside oil pipe's friction damage, and the siltation clay and grit harden the back very hard, the clearance difficulty, high labor strength, the problem of the operating efficiency of influence vehicle.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an excavator mud scraping device, includes welded plate, short supporting plate, long supporting plate, layering, scrapes skin and countersunk head bolt, the welded plate divides two on the left and right sides to weld into trapezoidally through short supporting plate and long supporting plate, the layering all has two with the skin of scraping, the bolt hole has been seted up on the welded plate, all bore the hole that matches with the welded plate bolt hole on layering and the skin of scraping, the skin of scraping passes through layering and countersunk head bolt and installs on the welded plate.
(III) advantageous effects
The utility model provides an excavator mud scraping device. The method has the following beneficial effects: the excavator mud scraping device has the advantages that through the self characteristic of rotation of the excavator body during operation of the excavator, once mud and sand enter the upper end face of the chassis, the mud and sand are scraped outwards by the scraping leather and cannot be deposited on the periphery of the turntable, a series of problems (friction of the end face of a vehicle body, damage of an oil pipe and reduction of related hydraulic system efficiency due to increase of rotating load) caused by deposition of the mud and sand on the periphery of the turntable are solved, the service lives of related parts of the excavator are prolonged, a driver is liberated from heavy cleaning operation, and the operation efficiency of a vehicle is improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an excavator mud scraping device which characterized in that: including welded plate 1, short supporting plate 2, long supporting plate 3, layering 4, scrape skin 5 and countersunk head bolt 6, two about welded plate 1 divides to weld into trapezoidally through short supporting plate 2 and long supporting plate 3, layering 4 and scrape skin 5 all have two, have seted up the bolt hole on the welded plate 1, all bore the hole that matches with welded plate 1 bolt hole on layering 4 and the skin 5 of scraping, scrape skin 5 and install on welded plate 1 through layering 4 and countersunk head bolt 6.
This excavator mud scraping device is the trapezium structure, intensity is high (prior art is the L shape, yielding damage), can not receive extrusion deformation to damage, scrape skin 5 simultaneously for the flexible body (make with belt conveyor sticky tape) with chassis up end 9, carousel lateral surface in close contact with, can not produce the friction and harm other parts because of the card income stone, it is better to clean the effect, install for the symmetry during the installation simultaneously, and two scrape skin 5 along slewing bearing central line symmetry slope certain angle installation, the excavator just can in time scrape the material that just gets into the chassis up end and sweep out (receive the centrifugal force that the fuselage rotation produced and scrape the guide effect of skin slope).
This excavator mud scraping device welds terminal surface 7 under the fuselage, it is trapezoidal, therefore, it is very firm, during the excavator operation, generally can not rotate a whole circle, this utility model takes the symmetry mounting means, no matter excavator corotation or reversal, can in time sweep the earth that just got into the chassis up end and throw out, owing to scrape skin 5 and adopt flexible material preparation can with organism in close contact with, can not block into stone friction parts, and scrape certain angle of skin slope, play outside water conservancy diversion effect, under the centrifugal force that the fuselage rotation produced and the guide effect of scraping the skin slope, it is better to clean the effect.
To sum up, the excavator mud scraping device has the advantages that through the self characteristic of rotation of the excavator body during operation of the excavator, once mud and sand enter the upper end face of the chassis, the mud and sand are scraped outwards by the scraping leather and cannot be deposited on the periphery of the turntable, a series of problems (car body end face friction, oil pipe damage, rotation load increase and related hydraulic system efficiency reduction) caused by deposition of the mud and sand on the periphery of the turntable are solved, the service lives of related parts of the excavator are prolonged, a driver is liberated from heavy cleaning operation, and the operation efficiency of a vehicle is improved.
