[0029] Figure 1 The structural schematic diagram of the cab with a fresh air system of the present invention is shown. As Figure 1 shown, the cab with a fresh air system of the present invention includes a cab body 1. The cab body 1 is the cab body of an agricultural vehicle.

[0030] Among them, traveling wheels 4 are provided at the bottom of the cab body 1 so that the cab body 1 can travel. And, a driver's seat 6 and a steering wheel 5 are also installed inside the cab body 1 so that the driver can sit on the driver's seat 6 and operate the steering wheel 5.

[0031] In the present utility model, a plurality of air suction and supply integrated plates 2 are provided inside the top of the cab body 1, and an air suction and supply integrated machine 3 is provided inside the rear part. Among them, the air suction and supply integrated plate 2 is used to send the filtered fresh air (air) into the cab body 1 under the action of the air suction and supply integrated machine 3, and extract the air inside the cab body 1, so as to provide fresh air for the cab body 1 and improve the working environment of the driver.

[0032] Figure 2 The structural schematic diagram of the air suction and supply integrated plate of the cab with a fresh air system of the present utility model is shown. As Figure 2 shown, each air suction and supply integrated plate 2 includes a plate body 21, and an air suction port 22 and an air supply port 23 arranged in the plate body 21. Through the air suction port 22, the air inside the cab body 1 can be extracted. Through the air supply port 23, the filtered fresh air (air) can be sent into the cab body 1.

[0033] Preferably, the air supply port 23 is arranged in the middle of the plate body 21 and the air suction port 22 is arranged on both sides of the air supply port 23. Thus, it is convenient to extract the air inside the cab body 1 and also convenient to send the filtered fresh air into the cab body 1.

[0034] More preferably, a partition net is provided at both the air suction port 22 and the air supply port 23. Thus, it helps to ensure safety.

[0035] Figure 3 The structural schematic diagram of the air suction and supply integrated machine of the cab with a fresh air system of the present utility model is shown. As Figure 3 shown, the air suction and supply integrated machine 3 includes a machine body 31, and an air suction fan 32 and an air supply fan 33 arranged in the machine body 31. Among them, the air suction port 22 is connected to the air suction fan 32 to suck the air inside the cab body 1. The air supply port 23 is connected to the air supply fan 33 to send the filtered air into the cab body 1.

[0036] In the present utility model, the air suction and supply integrated plate 2 is connected to the air suction and supply integrated machine 3 through a composite pipe.

[0037] Figure 4 The structural schematic diagram of the composite pipe of the cab with a fresh air system of the present utility model is shown. As Figure 4 shown, the composite pipe includes an outer pipe 7 and an inner pipe 8 arranged concentrically. A fresh air channel is formed inside the inner pipe 8, and an air channel is formed between the outer pipe 7 and the inner pipe 8.

[0038] One end of the inner pipe 8 is provided with a fresh air inlet 9, and the other end is provided with a fresh air outlet 10. One end of the outer pipe 7 is provided with an air inlet 11, and the other end is provided with an air outlet 12. The fresh air inlet 9 is connected to the air supply fan 33, and the fresh air outlet 10 is connected to the air supply opening 23. The air inlet 11 is connected to the air suction opening 22, and the air outlet 12 is connected to the air suction fan 32.

[0039] Thus, the utility model adopts a composite pipeline, so that heat exchange can be carried out between the air in the cab and the air introduced from the outside, reducing the loss of heat or cold air in the cab.

[0040] As Figure 5 shown, the outer pipe 7 and the inner pipe 8 are fixedly spaced apart by a support frame 13. Thus, it is convenient for the fixed connection between the outer pipe 7 and the inner pipe 8.

[0041] In the utility model, the air supply fan 33 is provided with a plurality of air filters. The plurality of air filters can be existing air filters in the prior art, as long as they can play the role of air filtration and purification, and there is no limitation on them. Thus, the air outside the cab body 1 can be extracted by the air supply fan 33 and filtered, and then the filtered fresh air is sent into the cab body 1 to improve the air environment in the cab body 1.

[0042] Preferably, the air suction fan 32 and the air supply fan 33 are connected by a pipeline. Thus, the air in the cab body 1 extracted by the air suction fan 32 can be transported to the air supply fan 33 through the pipeline, and after being purified by the air supply fan 33, it is sent into the cab body 1 again. In this way, the introduction of external air can be reduced.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit the protection scope of the utility model. Those skilled in the art can modify or equivalently replace the technical solutions of the utility model according to the idea of the utility model, without departing from the essence and scope of the technical solutions of the utility model.
