Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to an excavator door panel. Background Art

[0002] An excavator, also known as an excavation machine or a backhoe, is an earth-moving machine that uses a bucket to dig materials above or below the surface of the machine and load them into a transport vehicle or unload them to a stockpile. Since the materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks, the dust content in its working environment increases. Most of the existing excavator door panels use glass windows as ventilation channels, which have no effective isolation effect on dust and other particulate matter, causing certain impacts on the health of drivers. Utility Model Content

[0003] The purpose of the present application is to provide an excavator door panel, aiming to solve the problem in the prior art that particulate matter in the external environment of the excavator cab cannot be effectively filtered.

[0004] An embodiment of the present application provides an excavator door panel, including a door panel body, which is connected to a cab door frame by a hinge; the door panel body is composed of a trapezoidal frame rib, transverse reinforcing ribs, oblique reinforcing ribs and a reinforcing steel plate; the transverse reinforcing ribs divide the trapezoidal frame ribs into three parts: upper, middle and lower, with a visual window installed in the upper part, a dustproof window, a door lock and a reverse lock in the middle part, and a foot window in the lower part; the dustproof window is composed of a fixed frame and a dust removal and noise reduction combination plate; the fixed frame is installed on the inner surface of the door panel by screws, and the dust removal and noise reduction combination plate is placed inside; the dust removal and noise reduction combination plate is divided into three layers, which are a filter screen, a dustproof plate and a sound insulation layer from the outer surface of the door panel inward; the dustproof plate is provided with multiple layers of overlapping waterproof plates, which are inclined to the ground and have a certain inclination angle with the horizontal plane.

[0005] The two ends of the oblique reinforcing ribs are respectively welded to the trapezoidal frame ribs and the transverse reinforcing ribs to form a triangular structure; the reinforcing steel plates have two pieces, covering both sides of the steel frame, and corresponding free space is left on the reinforcing steel plates for installation.

[0006] The visual window comprises a window frame, inner glass, outer glass and a sealing strip, and the visual window is fixed to the reinforcing steel plate on the upper part of the trapezoidal frame ribs by screws.

[0007] A guide rail is provided at the lower part of the frame of the vision window, and the inner glass and the outer glass are staggeredly installed on the guide rail; sealing strips are attached to the four sides of the vision window frame; the inner glass and the outer glass are sealed by the sealing strips; and push-pull handles are provided on the sides of the inner glass and the outer glass.

[0008] The filter screen is made of metal, the sound insulation board is made of sound-absorbing cotton, and the sound-absorbing cotton is pasted on the back of the dustproof board.

[0009] The foot window is a double-layer square glass, which is adhered to the reinforcing steel plate at the bottom of the trapezoidal frame rib by glass glue, and is surrounded by sealing strips.

[0010] The beneficial effect of the utility model is that a dustproof window is added on the basis of retaining the original visual window, which can not only ensure the original ventilation path, but also effectively isolate external noise and particles such as dust when the window is closed, thereby ensuring clean air circulation in the cab.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3The door panel of an excavator shown in the figure comprises a door panel body, which is connected to the door frame of the cab through a hinge; the door panel body is composed of a trapezoidal frame rib 1, a transverse reinforcing rib 2, an oblique reinforcing rib 3 and a reinforcing steel plate 4; the transverse reinforcing rib 2 divides the trapezoidal frame rib 1 into three parts: upper, middle and lower. The upper part is provided with a visual window 19, the middle part is provided with a dustproof window 7, a door lock 5 and a reverse lock 6, and the lower part is provided with a foot window 8; the dustproof window 7 is composed of a fixed frame 17 and a dust removal and noise reduction combined plate; the fixed frame 17 is installed on the door panel by screws The inner surface has a dust removal and noise reduction composite plate placed inside; the dust removal and noise reduction composite plate is divided into three layers, which are a filter screen 12, a dustproof plate 13 and a sound insulation layer 14 from the outer surface of the door panel inward; the dustproof plate 13 can be purchased independently on the shopping platform, and is a metal plate with holes. A plurality of overlapping waterproof plates 15 are arranged on the dustproof plate 13, and the waterproof plates 15 are inclined toward the ground and have a certain inclination angle with the horizontal plane; the downward inclination can make the dust falling on the waterproof plate fall naturally under the action of gravity, thereby maximizing the service life.
