[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-4 A kind of engineering machinery cockpit cooling and ventilation device, including first mounting frame 1, stabilizing mechanism, dustproof mechanism, fixed mechanism and protection mechanism, the inside of first mounting frame 1 is provided with wind direction adjusting mechanism, wind direction adjusting mechanism includes open groove 2, the inside of first mounting frame 1 is provided with sliding groove 3, the inside of sliding groove 3 is provided with slip ring 4, the inner side of slip ring 4 is rotatably connected with fan blade 5, the inside of first mounting frame 1 is provided with screw 6, the outside of screw 6 is provided with second mounting frame 7, the inside of second mounting frame 7 is provided with thread groove 8, the inside of second mounting frame 7 is provided with installation groove 9, installation groove 9 is fixedly connected with connecting rod 10 in the inside, one end of connecting rod 10 is fixedly installed with cooling fan 11, thread groove 8 is set in the inside of second mounting frame 7, open groove 2 is set in the inside of first mounting frame 1, slip ring 4 is slidably connected with sliding groove 3, screw 6 is set in thread groove 8 and is threadedly connected with thread groove 8, the sliding groove 3 in the inside of first mounting frame 1 provides sliding track for slip ring 4, driver manually operates slip ring 4 to drive the rotation of the inner fan blade 5, and the manual adjustment of multidirectional wind direction is realized by cooperating with the dialing of fan blade 5, it is simple and intuitive to operate. Screw 6 cooperates with the thread groove 8 of second mounting frame 7, the distance between first mounting frame 1 and second mounting frame 7 is changed by rotating screw 6, this design reserves sufficient space for the maintenance of wind direction adjusting mechanism, and maintenance work can be completed without disassembling a large number of components, the connecting rod 10 in installation groove 9 fixes cooling fan 11, and the two rows of cooling fans 11 have clear division of labor, guaranteeing that air circulation is smooth.

[0021] In one aspect of the embodiment, the magnets 12 inside the first mounting frame 1 and the second mounting frame 7 are attracted to each other when they are close to each other, thereby enhancing the overall stability of the device, preventing the first mounting frame 1 and the second mounting frame 7 from loosening or shifting in the vibration environment of the engineering machinery, and ensuring the stable operation of the wind direction adjusting mechanism and the cooling fan 11.

[0022] In one aspect of the embodiment, the setting frame 13 is fixed inside the second mounting frame 7, and the two mounting plates 14 firmly fix the gauze 15. When the second mounting frame 7 is installed in place through the fixing mechanism, the gauze 15 is just at the air inlet, preliminarily filters the air entering the device, effectively reduces the dust and impurities entering, reduces the wear of components such as the cooling fan 11, and prolongs the service life of the device.

[0023] In one aspect of the embodiment, the four fixing plates 16 are distributed on both sides of the second mounting frame 7, and the device is stably installed at a specified position in the cab through the fixing holes 17 and connecting members such as bolts, so as to ensure that the device does not shake during operation. The rubber pad 18 on the front side of the first mounting frame 1 not only prevents personnel from being injured by collision, but also matches the groove 2 through the setting groove 19 on the surface, thereby protecting the wind direction adjusting mechanism without affecting the operation of the fan blade 5 and the air outlet.

[0024] The working principle of the utility model is as follows: when the engineering machinery cab cooling and ventilation device is used, the driver can rotate the fan blade 5 by manually rotating the slip ring 4 during operation of the device, so as to flexibly adjust the wind direction. Whether air is sent to the top of the cab to strengthen air convection or the driver's body is directionally blown, the operation can be performed as required. When the wind direction adjusting mechanism needs to be overhauled, the threaded rod 6 is rotated to move in the threaded groove 8, so as to change the distance between the first mounting frame 1 and the second mounting frame 7, thereby expanding the maintenance space, and facilitating maintenance and replacement of components such as the fan blade 5 and the slip ring 4. In the normal working state, the fixing mechanism stably installs the second mounting frame 7 in the cab through the fixing holes 17 on the fixing plates 16, so that the gauze 15 in the setting frame 13 is just located at the air inlet position, filters the air entering the device, blocks dust and sundries from entering, and protects the internal precision components such as the cooling fan 11. At the same time, the two rows of cooling fans 11 work cooperatively. One row is responsible for sucking external cold air, and the other row is responsible for discharging hot air in the cab, thereby forming continuous and efficient air circulation, creating a comfortable working environment for the driver, and all electrical equipment in the scheme is powered through an external power supply.

[0025] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
