Problems solved by technology
[0004] The space in the driver's cab is limited, and it is generally necessary to arrange various controls and electrical equipment, while the air supply duct and return air duct of the air conditioner will obviously take up more space
Moreover, during the manufacturing process, after the main structure of the driver's cab is completed, pipeline laying and other work need to be carried out separately, which prolongs the manufacturing cycle
[0005] In the prior art, when heating is needed in winter, the warm air sent by the air conditioner can only be sent out through the upper ventilation system. However, due to the low density of general hot air, it is not easy to transfer heat downwards, and it is easy to cause uneven temperature distribution in the driver's cab, which will make the operation The temperature of the foot area is relatively low, and the comfort is relatively poor
[0006] In addition, due to the lack of internal pressure in the driver's cab in the prior art, after the driver's cab door is opened, external dust can easily enter the driver's cab

The invention discloses a cab of a mining excavator and the mining excavator. The cab of the mining excavator is mainly composed of an integrated vent pipe, a return duct, an upper air supply system, a lower air supply connector, an air supply outer connector, an air return inner connector and an air return outer connector. The integrated vent pipe comprises a main air supply pipe and a lower air supply pipe. The upper air supply system supplies air to a cab body from the top. The lower air supply inner connector supplies air to the cab body from the bottom. The air supply outer connector and the air return outer connector are connected with an air-conditioning device which communicates with the main air supply pipe through the air supply outer connector. The air-conditioning device communicates with the air return pipe through the air return outer connector. The air-conditioning device sucks the air in the cab body through the air return pipe. According to the cab of the mining excavator, an air-conditioning air supply pipeline and / or an air return pipeline are / is integrated into the circumferential wall of the cab body, so that the inside space of the cab body is optimized, and manufacturing processes are saved.
Description
technical field [0001] The present invention generally relates to a mining machine, in particular to a driver's cab of a mining excavator with a novel ventilation system and the mining excavator. Background technique [0002] The driver's cab of a mining excavator is the control center of the entire equipment. Factors such as the spatial layout of the driver's cab, operating field of view, visual experience, and ambient temperature can affect the comfort of the operator. If the work efficiency of the operator can be improved by improving the comfort, it is equivalent to improving the production efficiency of the equipment. [0003] The air-conditioning ventilation system of the mining excavator driver's cab of the prior art, such as figure 1 , figure 2 , image 3 As shown, the air-conditioning and ventilation system of the driver's cab 9 mainly includes a stand-alone air conditioner 91 , an air supply duct 92 , an air return duct 93 , an air supply diversity box 94 and a...
