Description

Technical Field

[0001] The utility model relates to an air filter intake cap installation structure for a loader, belonging to the technical field of air intake systems. Background Art

[0002] At present, the air intake system of wheel loaders on the market has an air filter assembly. The air inlet of the air filter assembly is equipped with an air filter inlet cap to prevent rain and falling objects from entering the air filter assembly and causing air filter failure, thereby affecting the normal use of the diesel engine. Usually, the air filter inlet cap is arranged on the top of the diesel engine.

[0003] like Figure 1 As shown, in the traditional air filter air inlet cap installation structure, the air inlet port communicating with the outside air is arranged above the air filter 4, and the air inlet port is exposed above the engine cover 2, the air filter air inlet cap 1 is fixed on the air filter air inlet cap transition pipe 3, and the air filter air inlet cap transition pipe 3 is fixed on the air filter 4. The air inlet of the air filter 4 is set upward, the air filter intake cap 1 passes through the top of the hood 2 and extends out of the hood 2 to inhale the air with a lower temperature from the outside. The air filter intake cap 1 exposed from the hood 2 needs to have a waterproof function in rainy days to prevent rainwater from entering the air filter 4 and causing the filter element to fail. During use, the air filter intake cap 1 exposed from the hood 2 greatly blocks the driver's rear view and affects the driver's safety when reversing. When the whole machine is a flip-up hood, in order to avoid the air filter intake cap 1 from interfering with the hood 2 during the flipping process, the hood needs to have a relatively large long hole to avoid it, which affects both the strength of the hood 2 and the waterproof effect of the power compartment. Since most of the diesel engines on the market are electronically controlled diesel engines with more electrical components and higher requirements for waterproofing, the long holes on the hood 2 cannot prevent the entry of rainwater, which greatly increases the failure rate of the diesel engine.

[0004] Therefore, there is an urgent need in the art for an air filter air inlet cap mounting structure for a loader that can conceal the air filter air inlet cap. Summary of the invention

[0005] The utility model aims to solve the problems of the driver's rear vision and the small opening of the flip cover in the prior art.

[0006] In order to achieve the purpose of solving the above-mentioned problems, the technical solution adopted by the utility model is to provide an air filter air intake cap installation structure for a loader, including an air filter air intake cap installed inside the hood and an air intake pipe arranged at the rear of the air filter air intake cap, the air intake pipe is connected to the air filter, and the air filter is arranged in the power compartment inside the hood; the air inlet port of the air filter is arranged on the side of the air filter and is located inside the hood, and the top of the hood is a closed structure.

[0007] Preferably, the air filter inlet cap is separated from the cabin by a partition and communicates with the atmosphere to provide an air intake passage.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. The air filter air intake cap installation structure provided by the utility model changes the problem of poor sealing of the hood opening caused by the structure of the air filter air intake cap installed on the top of the hood in the traditional structure. It has a simple structure, flexible assembly, better assembly and use performance, solves the problem of large hood opening (especially the structure where the entire hood can be opened, the opening is larger than that of the non-open structure), greatly improves the reliability of the diesel engine; and solves the problem of the air filter air intake cap blocking the rear view, greatly improving the safety of the driver's reversing.

[0013] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0014] like Figure 2 As shown, the utility model provides an air filter air inlet cap installation structure for a loader, which is an improvement on the traditional air filter air inlet cap installation structure, eliminating the air inlet opening of the hood 2 and canceling the traditional air filter air inlet cap 1 extending out of the hood 2. Figure 2 As shown, it includes an air filter 4 and an air intake hose 5. The air filter intake cap 1 mounting structure is located inside the hood 2. The air inlet of the air filter 4 is arranged on the side of the air filter 4. The air filter 4 is installed in the power compartment inside the hood 2. The top of the hood 2 is a closed structure. An installation position for the air filter intake cap 1 is reserved inside the hood 2 and is separated from the power compartment by a partition 6, and is connected to the atmosphere to provide an air intake channel.

[0015] Through the structure of the utility model, the air intake opening of the hood 2 is omitted, and the conventional structure of the air filter air intake cap 1 extending out of the hood 2 is cancelled. The air filter air intake cap 1 installation structure is located inside the hood 2, the air intake port of the air filter 4 is arranged on the side of the air filter 4, the air filter 4 is installed inside the hood 2, the top of the hood 2 is a closed structure, the air filter air intake cap 1 installation position is reserved inside the hood 2 and is separated from the power cabin by a partition 6, and is communicated with the atmosphere to provide an air intake channel.

[0016] Since the air filter intake cap 1 is arranged inside the hood 2, the problem of the traditional air filter intake cap 1 extending out of the hood 2 assembly to block the rear view is solved, which greatly improves the safety of the driver's reversing driving; and the air filter intake cap 1 is arranged inside the hood 2, so that the top of the hood 2 can achieve a closed structure, which solves the problem of the large hood opening (especially the structure in which the entire hood can be opened, the opening is larger than that of the non-open structure), which not only strengthens the structural strength of the hood 2 but also effectively prevents rainwater from entering the power compartment and wetting the electrical components of the diesel engine, greatly improving the reliability of the diesel engine; the structure of the utility model can also achieve the function of waterproofing on rainy days.

[0017] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
