Abstract

A W-shaped scraper knife for a bulldozer comprises a knife head, a baffle plate, a knife corner and a knife blade. The knife head is a main piece and wholly in the structure of a rectangular arc shape with a convex middle part, the baffle plate is arranged at two ends of the knife head, the knife blade is arranged at the lower end edge of the knife head, and the lower end of the baffle plate is connected and provided with the knife corner. As the knife head is set to be in the arc shape with the convex middle part, the stress area of the bottom of a scraped object is enlarged, so that more soil can be rolled when the bulldozer shovels or tunnels; and the convex middle part and the baffle plate at two sides form a groove, so that the soil is prevented from overflowing towards two sides in the tunneling process. The W-shaped scraper knife for the bulldozer wholly has a simple structure, is convenient in operation and use, and is good in stability and high in reliability. In the utility model, the middle part of the knife head is in a convex structure, and the convex part and the baffle plates at two sides form the groove, so that the cross section of the scraper knife is W-shaped. For the W-shaped scraper knife for the bulldozer, the stress area at the bottom of the scrapped object can be enlarged due to the middle convex part, so that the more soil can be rolled when the bulldozer scraps or tunnels.

Description

A kind of W shape bulldozer perching knife

Technical field

The utility model relates to the functional device that engineering reaches, and relates in particular to a kind of W shape bulldozer perching knife.

Background technology

The perching knife shape of present domestic bulldozer has the shovel that directly inclines, u blade, half u blade, angle shovel etc.; The perching knife cutter head soil-shifting face of these shapes all is smooth; It is less to scoop up thing bottom lifting surface area when shovel soil or driving, and it is excessive to both sides easily to push ahead in the process soil.To above-mentioned situation; Design a kind of W shape bulldozer perching knife; The part of perching knife intermediate projections has increased the lifting surface area that scoops up thing bottom, and it is excessive to both sides that the groove of bossing and the formation of two side shield plates has reduced in the progradation soil, has increased the soil-shifting amount of single shovel; Improve operating efficiency, had very high practical value.

Summary of the invention

The purpose of the utility model is; Overcome the weak point of prior art; A kind of W shape bulldozer perching knife is provided, in the middle of the bulldozer perching knife, increases bossing, this bossing and two side shields form groove; Make the perching knife cross section be the W shape; The bulldozer perching knife intermediate projections of this form has partly increased the lifting surface area that scoops up thing bottom, make bulldozer bulldoze or the soil rolled during driving more, it is excessive to both sides that the groove that forms between intermediate projections part and two side shields can effectively reduce in the progradation soil.

The described a kind of W shape bulldozer perching knife of the utility model includes cutter head, baffle plate, nose angle and blade and forms.Cutter head is the main component of the utility model, and integral body is the structure of the rectangular arc of intermediate projections, and the two ends of cutter head are provided with baffle plate, and the lower end edge of cutter head is installed and is provided with blade, and the lower end of baffle plate is connected with nose angle.Cutter head is set to the arc of intermediate projections, has increased the lifting surface area that scoops up thing bottom, and the soil of rolling when making soil-shifting mechanical shovel soil or driving is more, intermediate projections part and two side shields form groove, has reduced excessive to both sides of soil in the progradation.

The described a kind of W shape bulldozer perching knife of the utility model, overall structure is simple, and is easy for operation, good stability, reliability is high.It in the middle of the cutter head of the utility model protruding structure; This bossing and two side shields form groove; Make the perching knife cross section be the W shape; The bulldozer perching knife intermediate projections of this form has partly increased the lifting surface area that scoops up thing bottom, make bulldozer bulldoze or the soil rolled during driving more, it is excessive to both sides that the groove that forms between intermediate projections part and two side shields can effectively reduce in the progradation soil.

Description of drawings

Accompanying drawing 1 is the structural representation of the said a kind of W shape bulldozer perching knife of the utility model.1-cutter head, 2-baffle plate, 3-nose angle, 4-blade.

The specific embodiment

With reference to accompanying drawing 1, explain as follows in conjunction with embodiment: the described a kind of W shape bulldozer perching knife of the utility model includes cutter head 1, baffle plate 2, nose angle 3 and blade 4 and forms.Cutter head 1 is the main component of the utility model, and integral body is the structure of the rectangular arc of intermediate projections, and the two ends of cutter head 1 are provided with baffle plate 2, and the lower end edge of cutter head 1 is installed and is provided with blade 4, and the lower end of baffle plate 2 is connected with nose angle 3.Cutter head 1 is set to the arc of intermediate projections, has increased the lifting surface area that scoops up thing bottom, and the soil of rolling when making soil-shifting mechanical shovel soil or driving is more, intermediate projections part and two side shields 2 form grooves, has reduced excessive to both sides of soil in the progradation.The described a kind of W shape bulldozer perching knife of the utility model, overall structure is simple, and is easy for operation, good stability, reliability is high.It in the middle of the cutter head of the utility model protruding structure; This bossing and two side shields form groove; Make the perching knife cross section be the W shape; The bulldozer perching knife intermediate projections of this form has partly increased the lifting surface area that scoops up thing bottom, make bulldozer bulldoze or the soil rolled during driving more, it is excessive to both sides that the groove that forms between intermediate projections part and two side shields can effectively reduce in the progradation soil.
