Description

Technical Field

[0001] This utility model relates to the technical field of cab booster equipment, and more specifically to a positive pressure booster for the cabs of agricultural machinery and engineering machinery. Background Technology

[0002] Agricultural machinery and construction machinery are two types of mechanical equipment used in agriculture and construction engineering, respectively. Currently, the pressurization equipment in the cabs of traditional agricultural and construction machinery uses a single fan to supply air into the cab. The fan inlet either lacks a filter or has only a standard filter. Without a filter, the fan easily blows outside dust into the cab, polluting the interior environment. If only a standard filter is installed, the filtration effect is poor, and dust and odors in the air are easily drawn into the cab by the positive pressure fan, resulting in poor positive pressure inside the cab. This needs improvement. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a positive pressure booster for the cab of agricultural machinery and engineering machinery to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a positive pressure booster for the cab of agricultural machinery and engineering machinery, including a booster housing, a housing cover on the top of the booster housing, the booster housing and the housing cover being fixedly installed by bolts, a booster fan being fixedly installed inside the booster housing, an air inlet being opened on the back of the booster housing, a filter paper filter element and an activated carbon filter element being provided inside the air inlet, the activated carbon filter element being located in front of the filter paper filter element, the filter paper filter element and the activated carbon filter element being installed inside the air inlet by a pull-out method, a filter element baffle being provided on the rear left side of the booster housing, the filter element baffle being connected to the booster housing by a plum blossom handle nut, the left side of the filter paper filter element and the activated carbon filter element overlapping the right side of the inner wall of the filter element baffle.

[0005] Furthermore, the booster fan is located in front of the activated carbon filter element.

[0006] Furthermore, the front of the booster housing has four exhaust vents, and the front of the booster fan has four outlet vents, with the four outlet vents of the booster fan corresponding to the four exhaust vents.

[0007] Furthermore, two mounting brackets are symmetrically fixedly connected to the lower front and back sides of the turbocharger housing, and the mounting brackets are fixedly connected to the corresponding mounting positions in the cab by bolts.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. This utility model, by employing a combination of a turbocharger housing, a filter paper filter element and an activated carbon filter element, a turbocharger fan and an exhaust port, facilitates the delivery of double-filtered air into the cab, increasing the oxygen content inside, eliminating fatigue, and preventing the intrusion of external dust, odors and harmful gases, thus protecting the driver's health.

[0010] 2. The filter element baffle of this utility model can be quickly disassembled and assembled, making it convenient to remove the filter paper filter element and activated carbon filter element from the inside of the air inlet, which facilitates cleaning dust from the filter paper filter element and activated carbon filter element or replacement.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The positive pressure booster for the cab of agricultural machinery and engineering machinery involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] like Figure 1-2As shown, a positive pressure turbocharger for agricultural and engineering machinery cabs includes a turbocharger housing 1, with a housing cover 7 on the top of the housing 1. The turbocharger housing 1 and the housing cover 7 are fixedly installed together by bolts. An air inlet is provided on the back of the turbocharger housing 1. Inside the air inlet, there is a filter paper filter element 4 and an activated carbon filter element 5. The activated carbon filter element 5 is located in front of the filter paper filter element 4. The filter paper filter element 4 and the activated carbon filter element 5 are installed inside the air inlet by a pull-out method. A filter element baffle 3 is provided on the rear left side of the turbocharger housing 1. The filter element baffle 3 is connected to the turbocharger housing 1 by a nut with a perforated handle. The compressor housing 1 is connected, and the left sides of the filter paper filter element 4 and the activated carbon filter element 5 overlap on the right side of the inner wall of the filter element baffle 3. A booster fan 6 is fixedly installed inside the booster housing 1. The booster fan 6 is located in front of the activated carbon filter element 5. Four exhaust ports 8 are opened on the front of the booster housing 1, and four air outlets are provided on the front of the booster fan 6. The four air outlets of the booster fan 6 are corresponding to the four exhaust ports 8. Two mounting brackets 2 are symmetrically fixedly connected to the lower front and back of the booster housing 1. The mounting brackets 2 are fixedly connected to the corresponding mounting positions in the cab by bolts.

[0016] In this embodiment, by setting the mounting bracket 2, the booster housing 1 can be fixedly installed in the designated position using bolts. After installation, it is only necessary to connect a power supply with the corresponding voltage (12V / 24) to operate the product. This product is controlled by a positive pressure control panel. The booster fan has four positions: low, medium, high, and stop. Users can select the air volume according to their individual needs.

[0017] In summary, such as Figure 1-2 As shown, this positive pressure booster for agricultural and engineering machinery cabs is used by fixing the mounting bracket 2 on the booster housing 1 to the corresponding installation position in the cab with bolts. Outside air enters the booster housing 1 through the air inlet and passes through the filter paper filter element 4 and the activated carbon filter element 5 to adsorb dust, fine particles and odors in the air. The filtered air is then driven by the booster fan 6 and sent to the corresponding air outlet in the cab through the exhaust port 8, making the pressure inside the cab higher than the outside pressure, thus achieving the positive pressure effect in the cab of agricultural and engineering machinery.
