Abstract
The utility model provides a bulldozer perching knife. According to the technical scheme of the utility model, three to five arc-shaped small-strip steel plates are uniformly arranged along the height direction of a perching knife panel. The thickness of the steel plates is 14-18 mm and the width thereof is 80-120 mm. The length of the steel plates is 75%-85% of the height of the perching knife panel. The small-strip steel plates are connected with the perching knife panel via the welding mode. Two high strength arc-shaped wear resistant steel plates are transversely arranged on the small-strip steel plate. The thickness of the wear resistant steel plates is 14-18 mm and the width thereof is 45%-48% of the width of the perching knife panel. The height of the wear resistant steel plates is 70%-80% of the height of the perching knife panel. The wear resistant steel plates are connected with the small-strip steel plates via the welding mode. According to the utility model, the surface of the perching knife is not easy to crack and the service life of the perching knife is prolonged. Meanwhile, the soil-shifting efficiency is improved. The restoration working load and the down time are effectively reduced. The utilization rate of equipments is also increased.
Description
Technical field
The utility model relates to a kind of bulldozer perching knife, belongs to mechanical field.
Background technology
Perching knife is the most serious as the groundwork mechanism wear of bulldozer, and the quality of perching knife directly influences the operating efficiency of bulldozer.When the bulldozer perching knife wore and tore, restorative procedure in the past was to paste the fritter wearing plate at the perching knife face, repair long in time limit, weak effect.
Summary of the invention
This practical purpose just provides a kind of bulldozer perching knife, and solution bulldozer repair amount is big, downtime long, the problem of repairing effect difference, improves the bulldozer operating mode, increases the service life.
The technical solution of the utility model is: it is that 14-18 millimeter, width are that 80-120 millimeter, length are little steel plate of arc of the 75%-85% of perching knife panel height that the short transverse of perching knife panel evenly is provided with 3-5 bar thickness, little steel plate is connected by welding manner with the perching knife panel, 2 thickness of horizontally set are that 14-18 millimeter, width are the 45%-48% of panel width, highly are the arc high-strength abrasion-proof steel plate of the 70%-80% of perching knife panel height on little steel plate, and wear-resisting steel plate is connected by welding manner with little steel plate.
The beneficial effects of the utility model are: the perching knife face is not easy to crack, has prolonged perching knife application life, has improved soil-shifting efficient, effectively reduces repair amount and downtime, has improved utilization rate of equipment and installations.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
