Its structure is directly related to the safety, work efficiency and health of the driver. The cab generally adopts a thin metal shell structure and is flexibly connected to the vehicle frame without bearing loads, belonging to a non-load-bearing body. Engineering vehicles are an essential type of large machinery in current construction, including loaders, bulldozers, excavators, rollers, etc. The above-mentioned engineering vehicles are basically operated and controlled by drivers in the cab;

[0003] However, during the working process, the heat generated by the engine will make the cab very hot, making the driver's working environment poor. Especially in summer, in order to complete a certain project, it is basically carried out under sunny weather, which makes the cab exposed to the scorching sun and the temperature inside the cab is very high. If the driver works for a long time, it will cause harm to the body.

[0004] Therefore, it is necessary to provide a new ventilation and heat dissipation type cab to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a ventilation and heat dissipation type cab.

[0006] The ventilation and heat dissipation type cab provided by the utility model includes a cab shell.

A servo motor for driving the driving gear to rotate is fixedly installed in the wind shield through a frame. A plurality of driven gears which are annularly distributed and rotatably connected are installed on the inner disc wall of the wind shield, and the driven gears are all meshed with the driving gear. A wind blocking disc is fixedly installed on each driven gear through a bracket.

[0010] Preferably, a filter screen A is fixedly installed at the end of the air inlet cylinder.

[0011] Preferably, the U-shaped air duct in the ventilation component is arranged on the inner bottom wall of the cab shell, and the middle pipe of the U-shaped air duct is located below the operating platform of the cab shell.

[0012] Preferably, the L-shaped air duct in the ventilation component is located at the corner at the rear side of the cab shell.

[0013] Preferably, the exhaust air duct has an L-shaped structure, and the horizontal pipe of the exhaust air duct extends out of the cab shell and faces the tail side of the cab shell.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model

[0023] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments

[0024] Please refer to Figures 1 to 4 , a ventilation and heat dissipation type cab provided by an embodiment of the present utility model, the ventilation and heat dissipation type cab includes: a cab shell 1, a ventilation component 2 and an exhaust duct 3

[0025] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , a ventilation component 2 is arranged in the cab shell 1, and the ventilation component 2 includes a U-shaped duct 21. Both ends of the U-shaped duct 21 are fixedly installed with L-shaped ducts 22. Horizontal pipe orifices of the two L-shaped ducts 22 are fixedly installed with air inlet cylinders 23. The two air inlet cylinders 23 are respectively fixedly embedded in an intake cavity 1a opened at the front end face of the cab shell 1 near the top. A plurality of exhaust holes 2a are opened on the pipe walls of the U-shaped duct 21 and the two L-shaped ducts 22. A windshield 25 is installed in each air inlet cylinder 23, and an air inlet hole 25a and a wind blocking member 26 for blocking the air inlet hole 25a are opened on the windshield

[0026] The wind blocking member 26 includes a driving gear 261. The driving gear 261 is rotatably installed at the rotation center of the inner disc wall of the windshield 25 through a rotating shaft. A servo motor 262 for driving the driving gear 261 to rotate is fixedly installed in the windshield 25 through a frame. A plurality of annularly distributed driven gears 263 rotatably connected are installed on the inner disc wall of the windshield 25, and the driven gears 263 are all meshed with the driving gear 261. A wind blocking disc 264 is fixedly installed on each driven gear 263 through a bracket

[0027] It should be noted that when the vehicle is running, the servo motor 262 is turned on to drive the driving gear 261 to rotate. Since the driving gear 261 is meshed and connected with the driven gear 263, the air blocking disc 264 on the driven gear 263 rotates and is misaligned with the air inlet hole 25a on the wind shielding disc 25. Therefore, the air flow generated during the vehicle's travel passes through the filter screen A24, enters the air inlet cylinder 23, then flows successively into the U-shaped air duct 21 and the L-shaped air duct 22, and is discharged into the cab housing 1 through the air discharge holes 2a opened in the U-shaped air duct 21 and the L-shaped air duct 22, thereby ventilating the cab housing 1, enabling the air flow to effectively dissipate heat from the cab housing 1. Therefore, the air outside the vehicle during driving is effectively utilized as a heat dissipation gas and introduced into the cab housing 1 to dissipate heat from the cab housing 1, enabling the gas inside the vehicle body to circulate, update, and purify continuously;

[0028] When the weather is bad, the servo motor 262 is reversed to reset the air blocking disc 264 to the corresponding air inlet hole 25a, so that the air blocking disc 264 closes the air inlet hole 25a, and the external air flow cannot flow into the air inlet cylinder 23;

[0029] Wherein, a filter screen A24 is fixedly installed at the end of the air inlet cylinder 23, so as to prevent dust in the air from entering the U-shaped air duct 21 or the L-shaped air duct 22;

[0030] Wherein, the U-shaped air duct 21 in the ventilation component 2 is arranged on the inner bottom wall of the cab housing 1, and the middle pipe of the U-shaped air duct 21 is located under the operation platform of the cab housing 1, while the L-shaped air duct 22 in the ventilation component 2 is located at the corner at the rear side of the cab housing 1. The positions of the U-shaped air duct 21 and the L-shaped air duct 22 can exhaust the air at the bottom and the rear side space of the cab housing 1, so that the fresh air at the bottom gathers and pushes the hot air gathered above the cab housing 1 to be discharged outside through the exhaust air duct 3.

[0031] In the embodiment of the present invention, please refer to Figure 1 and Figure 4 , a plurality of equally spaced exhaust air ducts 3 are installed at the top of the cab housing 1 near the rear end face, and an exhaust fan 31 is installed in each of the exhaust air ducts 3. The exhaust air duct 3 has an L-shaped structure, and the horizontal pipe of the exhaust air duct 3 extends out of the cab housing 1 and faces the tail side of the cab housing 1. Filter screens B32 are installed at both ends of the exhaust air duct 3.

[0032] It should be noted that: By turning on the exhaust fan 31 in the exhaust duct 3, the hot air accumulated in the cab shell 1 can be exhausted outside the cab shell 1, and the air entering the U-shaped air duct 21 or the L-shaped air duct 22 is coordinated, so that the hot air floats upward, further accelerating the ventilation and heat dissipation effects of the cab shell 1.

[0033] The working principle of the ventilation and heat dissipation type cab provided by the present utility model is as follows:

[0034] When the vehicle is running, turn on the servo motor 262 to drive the driving gear 261 to rotate. Since the driving gear 261 is meshed and connected with the driven gear 263, the wind blocking disc 264 on the driven gear 263 rotates and is misaligned with the air inlet hole 25a on the wind shielding disc 25. Therefore, the air flow generated during the vehicle's travel passes through the filter screen A24 and enters the air inlet cylinder 23, and then flows into the U-shaped air duct 21 and the L-shaped air duct 22 in sequence, and is discharged into the cab shell 1 through the exhaust holes 2a opened in the U-shaped air duct 21 and the L-shaped air duct 22, thereby ventilating the cab shell 1, enabling the air flow to effectively dissipate heat from the cab shell 1. Therefore, the air outside the vehicle during driving is effectively utilized as the heat dissipation gas to be introduced into the cab shell 1 to dissipate heat from the cab shell 1, enabling the gas inside the vehicle body to circulate, update, and purify continuously. At the same time, turn on the exhaust fan 31 in the exhaust duct 3, so that the hot air accumulated in the cab shell 1 can be exhausted outside the cab shell 1, and the air entering the U-shaped air duct 21 or the L-shaped air duct 22 is coordinated, so that the hot air floats upward, further accelerating the ventilation and heat dissipation effects of the cab shell 1;

[0035] When the weather is bad, reverse the servo motor 262 to make the wind blocking disc 264 reset to the corresponding air inlet hole 25a, so that the wind blocking disc 264 closes the air inlet hole 25a, and the external air flow cannot flow into the air inlet cylinder 23.

[0036] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
