Technical Field

[0001] This utility model belongs to the field of excavator parts technology, specifically relating to an excavator side door. Background Technology

[0002] Excavators are indispensable construction machinery in the field of engineering machinery. They often face various harsh working environments. The side door is an important external cover for excavators, which can protect the components of the excavator's power, hydraulic and other systems. At the same time, it can meet the maintenance and repair of these components and play a role in ensuring the smooth air intake of the heat dissipation module.

[0003] To ensure ventilation and protection, traditional side doors use holes directly drilled into the metal door panel to create ventilation openings. High-end side doors will have metal dustproof mesh installed on the inside to protect against small impurities such as dust.

[0004] Traditional side doors have holes directly drilled in the metal door panel, which makes it difficult to effectively block small impurities such as dust, resulting in poor dust protection.

[0005] High-end side doors are often fitted with metal dust screens, but these screens are expensive to manufacture, inconvenient to install and remove, difficult to clean of dust and other impurities, and prone to rusting. Utility Model Content

[0007] An excavator side door includes an outer door panel and an inner door panel. A dustproof net is connected to the inner side of the inner door panel. The dustproof net is installed on the inner door panel by expansion bolts or Velcro. A ventilation opening is provided on the outer door panel. A first ventilation net is provided on the inner door panel. The dustproof net includes a frame and a second ventilation net. The second ventilation net covers the inner side of the first ventilation net.

[0008] Preferably, the upper end of the frame is connected to the inner door panel by a spring.

[0009] Preferably, the inner door panel is provided with mounting holes, a button ring is fixedly connected to the dustproof mesh, one end of the spring is connected to the mounting hole, and the other end is connected to the button ring.

[0010] Preferably, the button ring is provided with a connecting hole, and the expansion nail passes through the connecting hole and the frame, connects to the inner door panel, and presses onto the button ring.

[0011] Preferably, the outer door panel is provided with a rivet bracket and a hinge bracket, and the inner door panel is connected to the rivet bracket by rivets.

[0012] Preferably, the hinge bracket is welded and fixed to the right side of the outer door panel.

[0013] Preferably, a limiting plate bracket for limiting and damping the opening and closing of the side door is welded to the left side of the outer door panel.

[0014] Preferably, a steel bar is fixedly connected to the upper end of the frame.

[0015] Preferably, the mesh shape of the first ventilation mesh is one of circular, square, rhomboid, or hexagonal.

[0016] Preferably, the mesh shape of the second ventilation mesh is one of round, square, rhomboid, or hexagonal.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By connecting a dustproof net to the inside of the inner door panel and setting up a first ventilation net and a second ventilation net, the entry of external dust and debris is effectively blocked, while ensuring air circulation, which significantly improves the cleanliness of the excavator's working environment and operating efficiency.

[0019] 2. By adopting innovative methods such as spring connection design and installation method combining loop and expansion nail, the manufacturing and installation process of dustproof nets is simplified, effectively reducing the manufacturing cost of side door dustproof nets;

[0030] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0031] Example 1

[0032] like Figure 1-6 As shown, an excavator side door includes an outer door panel 1 and an inner door panel 2. A dustproof net 3 is connected to the inner side of the inner door panel 2. The dustproof net 3 is installed on the inner door panel 2 by expansion nails 4 or Velcro 13. A ventilation opening is provided on the outer door panel 1, and a first ventilation net 21 is provided on the inner door panel 2. The dustproof net 3 includes a frame 31 and a second ventilation net 32. The second ventilation net 32 ​​covers the inside of the first ventilation net 21, effectively preventing dust and debris from entering the excavator while ensuring air circulation. This overcomes the problem of poor dustproof performance of side doors in the prior art and improves the operating efficiency of the excavator and the cleanliness of the working environment.

[0033] Specifically, ventilation openings are arranged in the upper, middle and lower parts of the outer door panel 1, and correspondingly, three of the first ventilation net 21 and the second ventilation net 32 ​​are also provided.

[0034] Specifically, the upper end of the frame 31 is connected to the inner door panel 2 by a spring 5, which gives the dustproof net 3 a certain elastic buffering capacity, enabling it to adapt to minor vibrations in different working environments, extend its service life, simplify the installation structure of the dustproof net 3, reduce manufacturing costs, and lower the manufacturing cost of the side door dustproof net 3.

[0035] Specifically, to make the installation and removal of the dustproof net 3 more convenient, the inner door panel 2 is provided with mounting holes, and a ring 6 is fixedly connected to the dustproof net 3. One end of the spring 5 is connected to the mounting hole, and the other end is connected to the ring 6. It can be easily completed without complicated tools, overcoming the problem of inconvenient installation and removal of the side door dustproof net 3 in the prior art, and improving maintenance efficiency.

[0036] Specifically, the ring 6 is provided with a connection hole. The expansion nail 4 passes through the connection hole and the frame 31 and is connected to the inner door panel 2 and pressed onto the ring 6. The installation method is stable and reliable, ensuring the stability of the dustproof net 3 in long-term use. It also simplifies the installation steps and further reduces the installation difficulty and cost.

[0037] Specifically, the outer door panel 1 is provided with a rivet bracket 7 and a hinge bracket 8. The inner door panel 2 is installed and connected to the rivet bracket 7 by rivets 12. The rivet 12 connection method makes the connection between the outer door panel 1 and the inner door panel 2 more secure, improves the overall strength and durability of the side door, and reduces the replacement and maintenance costs of the connecting parts.

[0038] Specifically, the hinge bracket 8 is welded and fixed to the right side of the outer door panel 1, and a limiting plate bracket 9 for limiting and damping the opening and closing of the side door is welded to the left side of the outer door panel 1. The welding and fixing method not only improves the smoothness of the opening and closing of the side door and reduces noise and wear, but also reduces the maintenance cost caused by loose or damaged connecting parts; furthermore, it is also equipped with a door lock 11, which is located on the left side.

[0039] Specifically, a steel strip 10 is fixedly connected to the upper end of the frame 31, which strengthens the structural strength of the frame 31 and makes the dustproof net 3 less prone to deformation or damage during long-term use, thus reducing the replacement cost caused by damage to the dustproof net 3.

[0040] Specifically, the first ventilation mesh 21 has a rhomboid mesh shape, and the second ventilation mesh 32 has a square mesh shape.

[0041] Example 2

[0042] like Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the dustproof net 3 is installed on the inner door panel 2 by Velcro 13, and the inner door panel 2 and the outer door panel 1 are also connected by Velcro 13, making the installation simple and quick.
