Air intake system and technical realization elements of engineering vehicles

Technical realization elements:

4. The purpose of the present utility model is to overcome the problems existing in the prior art and provide an air intake system and an engineering vehicle. The air intake system has low requirements for pipeline sealing and can extend the oil replacement cycle.

5. In order to achieve the above objective, one aspect of the present utility model provides an air intake system, the air intake system includes an oil pre-type filter, a rotary ash filter, an air filter and a box; the rotary The ash type filter is configured to filter large particles of dust, the oil pre-type filter is configured to filter small particles of dust; the box body is a sealed structure, and the oil pre-type filter is arranged at the place The inside of the box; the box includes an ash collection chamber, the ash collection chamber is respectively connected with the ash rotary filter and the oil pre-filter, the air filter and the The oil pre-filter is connected.

6. Optionally, the top of the box body is provided with a through hole communicating with the ash collection chamber, and the ash rotating filter is arranged on the top of the box body and communicates with the through hole through the through hole. The ash collection chamber is connected.

7. Optionally, an ash collection tank is provided at the bottom of the ash collection chamber, and the ash collection tank is provided corresponding to the through hole.

8. Optionally, the number of the oil pre-filter is multiple, and the multiple oil pre-filters are all connected to the ash collection chamber.

9. Optionally, the box body includes an airflow channel, one end of the airflow channel is communicated with the ash collection chamber, and the other end is respectively communicated with a plurality of the oil pre-filters, wherein the airflow One end of the channel communicating with the ash collection chamber is located at the upper part of the ash collection chamber.

10. Optionally, the box body includes a sealed chamber, and the sealed chamber is respectively communicated with a plurality of the oil pre-filters and the air filters.

11. Optionally, the box body includes a first partition plate and a second partition plate, the first partition plate and the second partition plate are arranged at intervals to separate the inside of the box body into the ash collector The chamber, the sealed chamber, and the installation chamber, wherein a plurality of the oil pre-filters are arranged in the installation chamber, and the sealed chamber is located between the ash collection chamber and the installation chamber. Between the chambers, the air flow channel passes through the sealed chamber and both ends are respectively connected to the ash collection chamber and the installation chamber.

12. Optionally, the air filter is arranged outside the box and located directly under the sealed chamber

square.

13. Optionally, a recessed portion is formed on the outer surface of the box body, and the air filter is located in the recessed portion.

14. Through the above technical solution, since the box body has a sealed structure and the oil pre-filter is arranged inside the box body, it is possible to prevent external dust from entering the oil pre-filter, This reduces the requirements for the tightness of the pipeline. In addition, since the ash collection chamber of the box body is respectively connected to the ash swirl filter and the oil pre-filter, the air passing through the ash swirl filter is not Large particles of dust that can be filtered will be deposited in the ash collection chamber, thereby avoiding the introduction of large particles of dust into the oil pre-filter, preventing the oil pre-filter from malfunctioning, and further improving This improves the air quality that finally enters the air filter, and prolongs the oil replacement cycle of the oil pre-filter.

15. The second aspect of the present invention provides an engineering vehicle, which includes the above-mentioned air intake system.

16. The engineering vehicle and the aforementioned air intake system have the same advantages over the prior art, and will not be repeated here.

17. Other features and advantages of the present utility model will be described in detail in the following specific implementation section.
