Abstract

The utility model discloses a wear-resisting bulldozer shovel which relates to the technical field of an engineering machine. The wear-resisting bulldozer shovel is composed of a left shovel, a middle shovel, and a right shovel. An upper edge and a lower edge of the utility model are covered with ribbon wear-resisting thin hard alloy layers with equal width and thickness. Left sharp corner edges, right upper sharp corner edges, and lower sharp corner edges of the left shovel and the right shovel are covered with thick hard alloy layers. The wear-resisting bulldozer shovel has the characteristics of simple integrated structure, long service life, good wear-resisting performance, and low cost.

Description

Wear-resisting bulldozer blade

The utility model relates to the soil-shifting workpiece in the engineering machinery.

Dozer in the engineering machinery be important in the engineering construction, also be operation part the most easy to wear, no matter bringing into play key effect at everyways such as building, construction of the highway, farmland capital constructions.At present, all kinds of dozers all adopt the general steel plate material, by heat-treatment technology methods such as carburizings to improve its performance.But because all multifactor influences such as materials, the abrasion resistance of dozer is still relatively poor, and especially the wearing and tearing of dozer cutting edge and sharp corner are faster, reduced the functional performance of dozer, improved use cost.

The purpose of this utility model is exactly lower application life at dozer, the technical problem of dozer cutting edge place anti-wear performance difference particularly, design provides a kind of Wear-resisting bulldozer blade, prolong dozer application life by near the upper and lower cutting edge place of dozer and left and right upper and lower sharp corner, covering the method for the extremely strong hard alloy layer of abrasion resistance, reaching, reduce the operation use cost, improve the purpose of functional performance.

Basic design of the present utility model is, evenly cover the wear-resisting thin hard alloy layer of ribbon that one deck width, thickness equate at the upper and lower cutting edge place of the left side of dozer shovel, middle shovel and right shovel, in addition be covered with the thick hard alloy layer of its thickness at upper left, the inferior horn of left side shovel and right shovel and upper right, inferior horn edge respectively, constitute Wear-resisting bulldozer blade greater than thin hard alloy layer.

The utlity model has simple in structure, method is simple for wearable hard alloy layer covering process, dozer long service life, characteristics with low cost, after cutting edge wearing and tearing under the dozer, upper and lower cutting edge interchangeable is installed and used, and has prolonged life cycle more.

Fig. 1 is a Wear-resisting bulldozer blade structural representation front view;

Fig. 2 is that the A-A of Fig. 1 is to sectional view.

Piece number explanation among the figure:

1. 4. thin hard alloy layer 5. thick hard alloy layers are shoveled on shovel 3. right sides in the left side shovel 2.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Wear-resisting bulldozer blade is made up of left side shovel 1, middle shovel 2 and right shovel 3, evenly be covered with the wear-resisting thin hard alloy layer 4 of ribbon that width, thickness equate at the upper and lower cutting edge place of left side shovel 1, middle shovel 2 and right shovel 3, be covered with the thick hard alloy layer 5 of its thickness respectively in the upper left corner of left side shovel 1 and the upper right corner and the lower right corner edge of the lower left corner and right shovel 3, constitute Wear-resisting bulldozer blade greater than thin hard alloy layer 4.Because cutting edge place and sharp corner at dozer have covered the wearable hard alloy layer, improved cutting edge and sharp corner abrasion resistance and prolonged useful life longevity.The place, upper and lower angle of left and right shovel 1,3 stressed big and complicated, wearing and tearing are more serious, thick hard alloy layer 5 has guaranteed the equal friction durability with thin hard alloy layer 4.After cutting edge hard alloy layer wearing and tearing under the Wear-resisting bulldozer blade, can be up and down and the left-right reversed position left, center, right three shovels, nearly one times of prolongation life cycle are installed.

Claims

1. configurable Wear-resisting bulldozer blade that uses on the various soil-shifting plant equipment that is installed in, this shovel is made up of left side shovel (1), middle shovel (2) and right shovel (3), it is characterized in that evenly being covered with the wear-resisting thin hard alloy layer (4) of ribbon that width, thickness equate, be covered with its thickness respectively greater than the thick hard alloy layer (5) that approaches hard alloy layer (4) in the upper left corner of left side shovel (1) and the upper right corner and the lower right corner edge of the lower left corner and right shovel (3) at the upper and lower cutting edge place of left side shovel (1), middle shovel (2) and right shovel (3).
