Description

Technical Field

[0001] This utility model relates to the field of bulldozer technology, and in particular to an air filter installation structure for bulldozers used in deserts. Background Technology

[0002] Bulldozers play a vital role in desert development and control. Due to the harsh desert environment and strong winds, the engine's air intake system is significantly affected. To address this issue, an additional stage of filtration is added to the bulldozer's air intake system. This air filter is installed high up to improve the filtration efficiency of the intake system. Currently, there are two main structures for installing high-mounted air filters in the industry:

[0003] (1) The air filter mounting bracket is welded to the top of the cab. This type of mounting bracket is fixed to the bottom of the cab by welding. Its installation contact area is small, and the bulldozer vibrates greatly when it is working. Long-term operation may cause local deformation of the top of the cab. In addition, when the OEM installs it, the materials are distinguished, which reduces the versatility.

[0004] (2) High-mounted air pre-filter, supported only by the intake pipe. This structure adds an air pre-filter to the intake system, but its filtration effect is somewhat worse than that of an air filter. In addition, since bulldozers vibrate greatly during operation, the exhaust pipe may crack after long-term operation due to being supported only by the intake pipe.

[0005] Given the shortcomings of the two installation methods mentioned above, it is necessary to design an air filter installation structure for bulldozers used in deserts to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air filter installation structure for bulldozers used in desert environments.

[0007] The technical solution of this utility model is: an air filter installation structure for a bulldozer used in the desert, including a first air filter fixed to the top of the bulldozer cab and a second air filter fixed inside the bulldozer cab; the first air filter is fixed to the protective handrail of the cab through a connecting mechanism; the air outlet of the first air filter is connected to the air inlet of the second air filter through a connecting hose.

[0008] The air inlet of the first air filter is equipped with a rain cap.

[0009] The connecting mechanism includes a mounting bracket; the mounting bracket has outwardly extending connecting rods at all four angles; the ends of the connecting rods are clamped to the protective handrails of the bulldozer cab by clamping block assemblies.

[0010] The upper clamping block and the lower clamping block; the upper clamping block is fixedly connected to the connecting rod; the two ends of the lower clamping block are fixedly connected to the two ends of the upper clamping block by bolts.

[0011] Both the upper and lower clamping blocks have clamping grooves in the middle that cooperate with the protective handrail.

[0012] The mounting bracket has multiple connection holes arranged in a matrix; the bottom of the first air filter is provided with threaded holes corresponding to the connection holes; the first air filter is fixed to the mounting bracket by a locking screw that passes through the connection holes and threaded holes.

[0013] The connecting hole is a waist-shaped hole.

[0014] The middle part of the connecting hose is fixed to the protective handrail on one side of the bulldozer cab by a clamp.

[0015] The filter elements of the first air filter and the second air filter are interchangeable.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects: (1) This utility model forms a dual filtration system by installing a first air filter on the top of the cab and connecting it with a second air filter inside the cabin. This structure can effectively filter the dust present in a large amount of sand in the desert, ensuring the cleanliness of the air entering the engine and improving the service life and working efficiency of the engine; at the same time, the first air filter is fixed to the protective handrail of the cab through a connecting mechanism, using the existing protective handrail as a support structure, without the need for additional installation brackets, saving space and making installation convenient. At the same time, the design of the connecting mechanism makes the filter installed firmly and can effectively resist the complex working conditions in the desert, such as bumps and vibrations.

[0017] (2) The present invention provides a rain cap at the air inlet of the first air filter, which can effectively prevent rainwater from entering the filter and avoid the filter element from becoming damp and failing. It can also prevent sand and dust from entering the filter with rainwater on rainy days, further improving the service life and reliability of the filter.

[0018] (3) The middle part of the connecting hose of this utility model is fixed to the protective handrail on the side of the cab by a clamp. This fixing method is simple and reliable, and easy to install and maintain. At the same time, the use of the clamp can ensure that the connecting hose remains stable under complex working conditions and avoids loosening or falling off due to vibration.

[0019] (4) The first air filter and the second air filter of this utility model are interchangeable, which reduces the types of filter elements and inventory costs. When replacing, only a new filter element needs to be replaced, which can ensure filtration efficiency, reduce maintenance costs, and improve the maintenance efficiency of the equipment.

[0020] (5) The mounting bracket of this utility model adopts a waist-shaped hole design for the connection hole, which allows the first air filter to be finely adjusted according to actual needs during installation, adapting to different size and position installation requirements, and enhancing versatility and adaptability.

[0021] (6) The upper clamping block and the lower clamping block in the connection mechanism of this utility model are connected by bolts and both are provided with clamping grooves that cooperate with the protective handrail. This design can ensure that the filter remains stable during operation and will not loosen or shift due to external force, thus improving the safety and reliability of the equipment.

[0027] (Example 1)

[0028] See Figure 1 and Figure 2 This embodiment describes an air filter installation structure for a bulldozer used in desert environments. It includes a first air filter 1 fixed to the top of the bulldozer cab and a second air filter 2 fixed inside the bulldozer compartment. The first air filter 1 is fixed to the protective handrail of the cab via a connecting mechanism 4. The outlet of the first air filter 1 is connected to the inlet of the second air filter 2 via a connecting hose 3. This structural design effectively filters sand and dust in the desert, ensuring the quality of air entering the engine. It also utilizes the space above the cab and the protective handrail for installation, saving space and facilitating installation.

[0029] Furthermore, a rain cap 5 is provided at the air inlet of the first air filter 1. The design of the rain cap 5 effectively prevents rainwater from entering the filter, avoiding filter element moisture damage and failure. It also prevents sand and dust from entering the filter with rainwater, further improving the service life and reliability of the filter. When the bulldozer is not used in harsh air environments such as desert conditions, the first air filter 1, mounting bracket 41, and connecting hose 3 can be removed, and the rain cap 5 can be installed at the air inlet of the second air filter 2 inside the cabin for normal use.

[0030] Furthermore, the connecting mechanism 4 includes a mounting bracket 41; each of the four angles of the mounting bracket 41 is provided with outwardly extending connecting rods 42; the ends of the connecting rods 42 are clamped to the protective handrail of the bulldozer cab by clamping block assemblies 43. The upper clamping block and the lower clamping block are described; the upper clamping block is fixedly connected to the connecting rods 42; the two ends of the lower clamping block are fixedly connected to the two ends of the upper clamping block by bolts. Both the upper and lower clamping blocks have clamping grooves 44 in their middle sections that cooperate with the protective handrail. This design ensures that the first air filter 1 is securely installed and adapts to the vibrations and bumps of the bulldozer under complex working conditions in the desert.

[0031] Furthermore, the mounting bracket 41 has multiple connecting holes 45 arranged in a matrix; the bottom of the first air filter 1 is provided with threaded holes corresponding to the connecting holes 45; the first air filter 1 is fixed to the mounting bracket 41 after being threadedly connected to the connecting holes 45 by a locking screw passing through the threaded holes. The connecting holes 45 are oblong holes. The oblong hole design allows for fine adjustment of the position of the first air filter 1 during installation to adapt to different sizes and installation requirements, enhancing the versatility and adaptability of the present invention.

[0032] Furthermore, the middle part of the connecting hose 3 is fixed to the protective handrail on one side of the bulldozer cab by a clamp 31. This fixing method is simple and reliable, and can effectively prevent the connecting hose 3 from loosening or falling off due to vibration during the operation of the bulldozer, ensuring the stability of air circulation.

[0033] Furthermore, the filter elements of the first air filter 1 and the second air filter 2 are interchangeable. This design reduces the types of filter elements and inventory costs, facilitates user procurement and replacement, and only requires replacing with a new filter element, ensuring filtration efficiency, reducing maintenance costs, and improving equipment maintenance efficiency.

[0034] This embodiment of an air filter installation structure for bulldozers used in desert environments improves the air filtration effect and equipment reliability of bulldozers in desert environments by optimizing the installation structure and connection method of the air filter, and reduces maintenance costs. It has significant practicality and innovation.
