[0018] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0019] like Figure 1-Figure 3As shown, the present embodiment provides a dust removal device for a combine harvester cab, comprising a cab body 1, an air intake case 3 fixedly mounted at the top center of the outside of the cab body 1, an exhaust fan 6 mounted on the top layer of the inner wall of the air intake case 3 by screws, a second filter screen 7 welded to the bottom of the exhaust fan 6; the bottom of the second filter screen 7 is connected to a second exhaust box 14, transparent door curtain frames 9 are symmetrically glued on both sides of the inner wall of the cab body 1, a transparent door curtain 10 is clamped in the transparent door curtain frame 9, and the transparent door curtains 10 are connected by a combination of magnetic strips 11; cabin doors 2 are hingedly mounted on both sides of the outside of the cab body 1, a transparent dust cover 8 is glued to the side of the cabin door 2 facing the inside of the cab body 1, and a sealing strip 13 is clamped on the top of the transparent dust cover 8.

[0020] A first filter 4 is embedded in the top of the air intake chassis 3. Both the first filter 4 and the second filter 7 are used to filter external gas. An air outlet filter box 16 is penetrated on both sides of the bottom of the cockpit body 1. The air outlet filter box 16 is connected to the outside. When the harvester is working, the external gas is turbid. At this time, the honeycomb filtration operation of the first filter 4 and the second filter 7 can improve the cleanliness of the circulating gas in the cockpit.

[0021] The interior of the transparent dust cover 8 is a hollow structure, and shunt pipes 5 are inserted on both sides of the outer wall of the air intake chassis 3. The bottom of the shunt pipe 5 passes through the cockpit body 1 and is connected to the air outlet groove 15. The first function of the transparent dust cover 8 is to improve the sealing of the cabin door 2. The second function is that when the cabin door 2 is opened, the air supply structure on the top can blow away the debris and dust gas surrounding the cabin door 2.

[0022] The air outlet groove 15 is communicated with the interior of the transparent dust cover 8 through a sealing sleeve, and the transparent dust cover 8 provides sealing for the connection between the cabin door 2 and the cockpit body 1 .

[0023] A first exhaust box 12 is embedded in the bottom of the transparent dust cover 8. The first exhaust box 12 and the second exhaust box 14 are both used for dispersing exhaust gas.

[0024] The transparent dust cover 8 and the transparent door curtain 10 are made of the same material, that is, transparent plastic material.

[0025] Working principle of this device: When the device is used, the electrical equipment is connected to the control console in the cockpit. There are two circulation gases in this device:

[0026] First circulation gas: the air intake box 3 draws in external air through the exhaust fan 6, and after being filtered by the first filter 4, enters the second filter 7 and the diverter pipe 5. The gas from the second filter 7 enters the cockpit body 1 through the micropores of the second exhaust box 14, promoting the air flow in the cockpit. The air flow is discharged from the air outlet filter box 16 to achieve clean gas selection and mixing;

[0027] Second circulating gas: 1. When the hatch 2 is opened and the user enters and exits the cockpit, the magnetic strip 11 can quickly close the transparent door curtain 10 to maintain the relative sealing of the cockpit. At the same time, the gas flowing out of the shunt pipe 5 blows away the gas and dust outside the transparent door curtain 10, and the gas flows outward to avoid more residue around the transparent door curtain 10, thereby reducing the amount of crop dust entering the cockpit; 2. When the hatch 2 is closed, the transparent dust cover 8 improves the sealing between the hatch 2 and the cockpit body 1, reducing the entry of dust and gas. At the same time, the gas flowing out of the shunt pipe 5 enters the transparent dust cover 8 from the air outlet groove 15, passes through the first exhaust box 12, enters between the transparent door curtains 10 in the cockpit, and delivers the clean gas into the cockpit through the gap, and the gas circulates inward.

[0028] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
