Problems solved by technology

However, an air conditioning system like this has a problem that the structure for rotating the valve plate is complicated
In addition, in the case of including a plurality of valve plates, there is also a problem that it is difficult to operate the fins provided at each air outlet, and it is impossible to quickly cope with the blurring of the front windshield.

Embodiment Construction

[0048] First, the tractor 1 will be briefly described. It should be noted that the technical idea of ​​the present invention can also be applied to other agricultural machinery vehicles, construction machinery vehicles and the like.

[0049] figure 1 Indicates tractor 1. The drawing shows the front-rear direction and the up-down direction of the tractor 1 .

[0050] The tractor 1 is mainly composed of a frame 11 , an engine 12 , a transmission 13 , a front axle 14 , and a rear axle 15 . In addition, a cabin 2 is provided on the tractor 1 .

[0051] The frame 11 forms the skeleton of the tractor 1 . An engine 12 and the like described below are mounted on the frame 11 .

[0052] The engine 12 converts energy obtained by burning fuel into rotational motion. If the operator operates the accelerator pedal 16, the engine 12 changes the operating state according to the operation. Also, even if the load changes, the engine 12 maintains a constant rotational speed.

Abstract

The air-conditioning duct 62 includes a plurality of ventilation ducts 62R, 62L for guiding the conditioned air. The ventilation ducts 62R, 62L include branch portions 62Rb, 62Lb constituting the main channel Fm and the branch channel Fb of the conditioned air. The branch portions 62Rb, 62Lb are included in the main channel Fm. and the flow path switching device 96 for adjusting the flow direction of air by switching between the branch flow path Fb. A linkage mechanism in which the valve plate 944 (934) on the splitter 62Lb (62Rb) is linked.

Description

technical field [0001] The invention relates to the technology of an air-conditioning duct structure of a cockpit. Background technique [0002] Currently, tractors with an air-conditioning system on the roof of the cabin are known. The air conditioning system adjusts the temperature and the like of air (hereinafter, the adjusted air is referred to as "adjusted air") and supplies it to the cabin through the air conditioning duct. Such an air-conditioning system contributes to the removal of fog on the windshield and the improvement of comfort in the cabin (for example, refer to Patent Document 1, Patent Document 2, and Patent Document 3). [0003] However, the volume of air blown from each air outlet is important to remove fog on the front windshield and improve the comfort in the cabin. Therefore, there is a technique in which a valve plate is provided inside the air-conditioning duct, and the valve plate is switched to adjust the flow path of the air. However, such an a...
