Description

Technical Field

[0001] This utility model relates to an excavator, and more specifically, to a bulldozer blade and an excavator. Background Technology

[0002] A bulldozer blade is an attachment for excavators, mounted on the excavator chassis for bulldozing or supporting the excavator. A bulldozer blade includes a blade, arm, and hydraulic cylinder. In some bulldozer blades, the blade and arm are fixedly connected; to strengthen the connection, reinforcing ribs are welded between them. These ribs are located on the outer side of the arm and the rear side of the blade. The upper reinforcing rib is usually horizontal, with its two welded edges parallel to the arm and blade.

[0003] When bulldozing, soil or mud often flows over the top of the blade and falls onto the reinforcing ribs. The existing horizontally arranged reinforcing ribs on bulldozer blades are not conducive to the falling of soil and mud. Soil and mud often accumulate on the top of the reinforcing ribs, which can easily lead to rust on the bulldozer blade and also affect the appearance of the machine. Utility Model Content

[0004] The technical problem this invention aims to solve is the issue of mud and water easily accumulating on the rear reinforcing ribs of a bulldozer blade. The invention provides a bulldozer blade and excavator that allow mud falling onto the rear reinforcing ribs of the blade to easily fall off and be removed.

[0005] The technical solution of this utility model to achieve its purpose is: a bulldozer blade, including a shovel arm and a blade welded to the end of the shovel arm. A reinforcing rib group composed of multiple reinforcing ribs is welded between the shovel arm and the blade. The topmost reinforcing rib in the reinforcing rib group is the upper reinforcing rib. The welding edge of the upper reinforcing rib to the blade is inclined. The height of the welding edge of the blade away from the end of the shovel arm is lower than the height of the welding edge of the blade near the end of the shovel arm.

[0006] In this new type of bulldozer blade, the upper reinforcing plate is triangular.

[0007] In this utility model bulldozer blade, the upper reinforcing plate has a downward-bent edge at its sloping side.

[0008] In this utility model bulldozer blade, the reinforcing rib group further includes a lower reinforcing rib plate, which is arranged below the upper reinforcing rib plate.

[0009] In this utility model bulldozer blade, the lower reinforcing plate is triangular, and its three sides are welded to the blade, the arm, and the bent edge of the upper reinforcing plate, respectively.

[0010] In this utility model bulldozer blade, the welded edge of the blade where the lower reinforcing plate is welded to the blade is inclined.

[0011] In this utility model bulldozer blade, the inclination angle of the welded edge of the lower rib plate blade is smaller than the inclination angle of the welded edge of the upper rib plate blade.

[0012] In this utility model bulldozer blade, the upper rib plate, the lower rib plate, the blade, and the arm are welded together to form a closed box-shaped structure.

[0013] In this utility model bulldozer blade, the upper reinforcing plate is welded to the blade at an inclined edge, and the height of the welded edge of the blade away from the blade end is lower than the height of the welded edge of the blade near the blade end.

[0014] The technical solution of this utility model to achieve its purpose is to disclose an excavator having the aforementioned bulldozer blade.

[0015] Compared with the prior art, in this utility model, the welding edge of the shovel of the upper rib plate is inclined, so that the upper rib plate is inclined. Water falling on it can slide down the slope, and soil can also slide down the slope under the vibration of the machine, thus avoiding the accumulation of mud and water on the reinforcing rib.

[0016] Figure 1 This is a schematic diagram of the structure of the bulldozer blade of this utility model.

[0017] Figure 2 This is a cross-sectional schematic diagram of the bulldozer blade of this utility model.

[0018] Component names and serial numbers in the diagram: 1. Shovel blade, 2. Shovel arm, 3. Reinforcing rib group, 31. Upper rib plate, 311. Shovel blade welded edge, 312. Shovel arm welded edge, 313. Bending edge, 32. Lower rib plate. Detailed Implementation

[0019] The specific implementation plan is described below with reference to the attached diagram.

[0020] like Figure 1 As shown, the bulldozer blade includes a shovel arm 2 and a blade 1 welded to the end of the shovel arm 2. A reinforcing rib group 3 composed of multiple reinforcing ribs is welded between the shovel arm 2 and the blade 1. The topmost reinforcing rib in the reinforcing rib group 3 is the upper reinforcing rib 31. The welded edge 311 of the blade to the upper reinforcing rib 31 is inclined. The height of the blade welded edge 311 away from the end of the shovel arm is lower than the height of the blade welded edge 311 near the end of the shovel arm. A preferred angle of inclination for the blade welded edge 311 is 10 degrees, that is, the angle between the blade welded edge 311 and the horizontal plane is 10 degrees.

[0021] After the bulldozer blade is installed on the excavator, the blade 1 is arranged horizontally, and the blade welding edge 311 of the upper stiffening plate 31 is arranged in an inclined manner, so that the upper stiffening plate 31 is also inclined. When there is mud and water on it, the mud and water will slide down along the slope of the upper stiffening plate 31, thereby avoiding the accumulation of mud and water on the upper stiffening plate 31.

[0022] The upper stiffening plate 31 is triangular. The shovel arm 2 and the shovel blade 1 are usually welded perpendicularly or approximately perpendicularly, and the upper stiffening plate 31 is a right-angled triangle or approximately a right-angled triangle. Optionally, the upper stiffening plate 31 has a downward-bent edge 313 at its hypotenuse. The bending edge 313 at the hypotenuse of the upper stiffening plate 31 can improve the strength of the upper stiffening plate 31.

[0023] Optionally, the reinforcing rib group 3 also includes a lower reinforcing rib 32, which is arranged below the upper reinforcing rib 31. Optionally, the lower reinforcing rib 32 is triangular, and its three sides are welded to the blade 1, the blade arm 2, and the bent edge 313 on the upper reinforcing rib 31, respectively.

[0024] The lower stiffening plate 32 can be arranged horizontally, that is, the scraper welding edge welded to the scraper 1 is parallel to the scraper, and the scraper arm welding edge welded to the scraper arm 2 is parallel to the scraper arm. In some embodiments, the scraper welding edge welded to the scraper 1 by the lower stiffening plate 32 can also be inclined, that is, the lower stiffening plate 32 is also arranged in an inclined manner. Preferably, the inclination angle of the scraper welding edge of the lower stiffening plate 32 is smaller than the inclination angle of the scraper welding edge of the upper stiffening plate 31.

[0025] Optionally, the upper stiffening plate 31, the lower stiffening plate 32, the scraper 1 and the scraper arm 2 are welded together to form a closed box-shaped structure, and the stiffening rib group forming the box-shaped structure has stronger strength.

[0026] In the above embodiments, only the blade welding edge on the upper stiffening plate 31 is arranged in an inclined manner. In some embodiments, the blade welding edge 312, where the upper stiffening plate 31 is welded to the blade arm 2, is also inclined. When the blade arm is in a horizontal state, the height of the blade welding edge 312 away from the blade end is lower than the height of the blade welding edge near the blade end. The upper stiffening plate 31 is inclined in both the front-back and left-right directions, making it easier for mud and water to fall off.

[0027] This embodiment also discloses an excavator having the aforementioned bulldozer blade.

[0028] In this embodiment, the shovel welding edge 311 of the upper stiffening plate 31 is inclined, so that the upper stiffening plate 31 is inclined. Water falling on it can slide down the slope, and soil can also slide down the slope under the vibration of the machine, thus preventing mud and water from accumulating on the stiffening rib.
