Detailed Description
The following describes specific embodiments of the present application in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the application, are not intended to limit the application.
The existing domestic 200-300 horsepower tractor mainly adopts the technical scheme of engine, mechanical gear shifting or partial power gear shifting products, such as the technical scheme of main speed change power gear shifting, auxiliary speed change mechanical gear shifting and power reversing, or the technical scheme of main speed change mechanical gear shifting, auxiliary speed change mechanical gear shifting, power reversing and power high and low gears. Due to the fact that the mechanical gear shifting assembly structure is arranged, the layout space inside the cab is limited, particularly the right side of the cab is frequently used for operation, the tightness of the cab is reduced due to the fact that the mechanical operating mechanism is used, and the tightness of the cab is poor due to the fact that the domestic cab frame is poor in sealing and assembling manufacturability, field operation dust is easier to enter the cab, and human health is damaged.
At present, the main measures for realizing sealing and noise reduction of the domestic cab are that soundproof cotton is added in the cab, sound absorbing cotton is stuck in the engine cover, a wire harness flexible shaft is sealed by using a sealing rubber sleeve, the cab is sealed by using an adhesive tape pressing foam, and the like, so that the sealing and noise reduction effect is better, but the sealing and noise reduction effect is also quite different from overseas brand models.
In view of this, as shown in fig. 1 and 2, the present application provides an agricultural driving machine including a fitted chassis assembly, a cab 1, and a supercharger 2. The cab 1 is arranged above the assembly chassis assembly and defines together with the assembly chassis assembly a mid-sandwich space in which the supercharger 2 is arranged for providing pressure to the cab 1. By additionally arranging the booster 2, the pressure can be provided for the cab 1, so that the indoor air pressure of the cab 1 is larger than the outdoor air pressure outside the cab, dust and harmful gas which is not filtered by the filter element are reduced, and enter the cab 1 through a cab gap, and a safe and comfortable driving environment is provided for a cab driver. The agricultural driving machine can be an intelligent high-horsepower power gear shifting wheel type tractor, a bulldozer, a land leveler and the like.
As shown in fig. 2, the supercharger 2 has an intake duct 21, an air outlet of the intake duct 21 communicates with the cab 1, and an air inlet of the intake duct 21 communicates with the intermediate space. Because the middle interlayer space between the cab 1 and the assembly chassis assembly is arranged in the agricultural driving machine and is a non-complete open space, air carrying dust and sand outside the agricultural driving machine enters the middle interlayer space through the structural gap between the cab 1 and the assembly chassis assembly, dust and sand in the air entering the middle interlayer space are reduced by a certain amount, and the air inlet pipeline 21 of the supercharger 2 sucks air from the middle interlayer space, so that the air in the air inlet pipeline 21 is cleaner. Meanwhile, the air inlet pipeline 21 is internally provided with the filtering device for filtering air inlet, so that air in the air inlet pipeline 21 is further cleaner, and the air suction port of the air inlet pipeline 21 is arranged in the middle interlayer space, so that the filtering pressure of the filtering device can be reduced, and the overall structure of the agricultural driving machine is more reasonable and reliable.
In some embodiments, as shown in fig. 2, the agricultural driving machine may further include an air conditioning system including an evaporator 31, an air conditioning compressor 32, a condenser 33, an evaporator fan, and a refrigerant line, and the evaporator 31, the air conditioning compressor 32, and the condenser 33 are sequentially connected through the refrigerant line. The air conditioning system is provided with an air outlet communicating with the cab 1, and the evaporator fan acts on the evaporator 31 and blows air towards the air outlet so that the evaporator 31 can deliver cool air to the cab 1. Wherein, the air outlet of the air inlet pipeline 21 is communicated with the air outlet of the air conditioning system, so that the supercharger 2 can charge air into the cab 1 through the air outlet of the air conditioning system. Because the supercharger 2 is arranged below the cab 1, and the evaporator 31 of the air conditioning system is arranged at the bottom of the cab 1, the structure of the agricultural driving machine can be more concise and reasonable. As shown in fig. 2, a supercharger 2 with a booster fan and a filter device is fixed at the right front lower end of the cab 1, and the supercharged air enters the interior of the cab 1 through an air inlet pipeline 21 and an air outlet of an air conditioning system.
Further, the agricultural driving machine may further include a control system, an internal air pressure detecting device provided in the cab 1 and configured to detect an indoor air pressure of the cab 1, and an external air pressure detecting device (shown in the drawing) provided outside the cab 1 and configured to detect an outdoor air pressure outside the cab.

When the driver closes the door and window to start the engine for preparation operation, the air pressure difference between the indoor air pressure and the outdoor air pressure is generally smaller than or equal to a first set value, and the booster fan of the controllable booster 2 can start a high-grade mode to quickly boost the cab, so that the boosting effect time of the cab 1 is shortened. When the cab 1 builds the set pressure, the booster fan will perform an intelligent mode, the air intake of which is smaller than that of the high-speed mode. When the air pressure difference value is larger than or equal to a second set value, namely the pressure in the cab is larger than a highest set pressure value, the booster fan is automatically turned off; otherwise, when the air pressure difference is larger than the first set value and smaller than the second set value, namely the pressure in the cab is lower than the highest set pressure value, the booster fan is automatically turned on to maintain the positive pressure effect of the cab.
Optionally, in order to make the agricultural driving machine more intelligent, the cab door and the cab window may be provided with position sensors for detecting the open and closed states, respectively, the position sensors being communicatively connected to a control system, the control system may be further configured to:

After determining that the engine in the powertrain is in a started state, and before acquiring the indoor air pressure detected by the internal air pressure detecting means and the outdoor air pressure detected by the external air pressure detecting means, it is determined that both the cab door and the cab window are in a closed state.
Since the booster 2 achieves the booster effect by pumping the external air into the cab 1, the booster 2 will be matched with the automatic air conditioning system to control, and the automatic air conditioner automatically controls the on/off of the air conditioning compressor 32 according to the set temperature requirement. At this time, the temperature in the cab can be monitored to change speed, when the temperature is lower than the set temperature, the air conditioner compressor 32 is turned off, and when the temperature is higher than the set temperature, the air conditioner compressor 32 is turned on, so that the influence of the supercharging system on the temperature of the cab is reduced.
In addition, in order to achieve a reduction of the influence of the supercharging system on the temperature of the cab, the agricultural driving machine may further comprise a warm air system and a temperature monitoring device, the warm air system comprising a warm water pipe 4 with a part of pipe sections arranged in the cab 1, a warm air water valve being arranged in the warm water pipe 4, the temperature monitoring device being arranged in the cab 1 and being arranged for detecting the indoor temperature of the cab 1, the control system being in communication connection with the warm air water valve and the temperature monitoring device, respectively, and being further configured to:
