[0002] The blower on a harvester is an indispensable part of agricultural machinery. It can effectively remove crop weeds and residues left on the ground after harvesting, ensuring the smooth progress of subsequent operations and improving agricultural production efficiency. When using it, attention should be paid to safety, and the blower should be used and maintained properly to extend the service life of the machine.

[0003] After harvesting, crop residue remains on the ground, which needs to be blown away by a front fan. However, existing front fans are quite long, so when they need to be inspected and cleaned, the device must be removed from the casing, which can cause inconvenience to the operators and affect work efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 One embodiment provided by this utility model:

[0026] A front fan for a harvester includes: a main body comprising a housing 1, a side plate 11 mounted on the surface of the housing 1, a rotating shaft 12 disposed on the inner side of the housing 1, a mounting bracket 13 fixedly connected to the surface of the rotating shaft 12, and blades 14 fixedly connected to the surface of the mounting bracket 13; the rotating shaft 12 is connected to a motor inside the harvester, and the motor drives the rotating shaft 12 to rotate, thereby causing the mounting bracket 13 and blades 14 to rotate together, generating wind to blow away harvested crop weeds and residues; and a connecting mechanism including a fixing plate 2 fixedly connected to the surface of the side plate 11. The surface of the housing 1 is fixedly connected to a fixing block 21 and a screw 26. The surface of the fixing plate 2 is fixedly connected to a rotating block 22. The surface of the fixing block 21 has a rotating hole 23. The surface of the side plate 11 is fixedly connected to a connecting plate 24 and a handle 29. The surface of the connecting plate 24 has a slot 25. The surface of the screw 26 is fitted with a nut 27. The surface of the nut 27 is fitted with a screw ring 28. There are two sets of fixing plates 2 and connecting plates 24, which are installed on both sides of the side plate 11. With the connection of the fixing plates 2 and the fixing block 21, the side plate 11 and the housing 1 can be connected.

[0027] The two sides of the fixed plate 2 are movably connected to the surface of the fixed block 21. Two sets of fixed blocks 21 and rotating blocks 22 are provided, and the two sets of fixed blocks 21 and rotating blocks 22 are installed on both sides of the fixed plate 2. The rotating block 22 is rotatably connected to the surface of the rotating hole 23. The diameter of the rotating hole 23 is the same as the diameter of the rotating block 22. With the connection of the rotating block 22 and the rotating hole 23, the fixed plate 2 and the two sets of fixed blocks 21 can be connected, so that the side plate 11 and the fixed plate 2 can rotate around the rotating block 22. One side of the connecting plate 24 is abutted against the surface of the housing 1, and the other side of the connecting plate 24 is fixedly connected to the surface of the side plate 11. The screw 26 is engaged with the surface of the slot 25. Under the action of the connecting plate 24, the rotation of the side plate 11 can be limited. The screw 26 can be installed through the slot 25. One end of the screw 26 is fixedly connected to the surface of the housing 1, and the other end of the screw 26 is threadedly connected to the inner surface of the nut 27. The nut 27 is abutted against the surface of the connecting plate 24. Both ends of the screw ring 28 are fixedly connected to the surface of the nut 27. The surface of the handle 29 is U-shaped. With the connection of the screw 26, the slot 25, and the nut 27, the connecting plate 24 can be limited and installed on the surface of the housing 1, thereby achieving the limited installation of the side plate 11. The screw ring 28 makes it easier and less strenuous to rotate the nut 27. Both ends of the handle 29 are fixed to the surface of the side plate 11. Moving the handle 29 can drive the side plate 11 to move.

[0028] A protective mechanism is provided on the inner surface of the housing 1. The protective mechanism includes a protective net 3, which is installed on the inner surface of the housing 1. A mounting frame 31 is fixedly connected to the surface of the protective net 3, and a mounting plate 32 is fixedly connected to the inner surface of the housing 1. The surface of the mounting frame 31 has insertion holes 33, and the surface of the mounting plate 32 has screw holes 34. Screws 35 are installed on the surface of the mounting frame 31. The mounting frame 31 is installed around the protective net 3, and the protective net 3 can be installed by installing the mounting frame 31. The mounting frame 31 is fitted to the inner surface of the housing 1. There are four sets of mounting plates 32 and insertion holes 33. The four sets of mounting plates 32 are located at the four ends of the mounting frame 31, and the four sets of insertion holes 33 are located at the four ends of the mounting frame 31. The size of the insertion holes 33 is larger than the size of the screw holes 34. The mounting plates 32 can be used to install the mounting frame 31 and the protective net 3, and the screws 35 can be installed by connecting the insertion holes 33 and the screw holes 34. Screw 35 is inserted into the surface of socket 33. One end of screw 35 is threaded into the surface of screw hole 34, and the other end of screw 35 is abutted into the surface of mounting frame 31. With the connection of screw 35, socket 33, and screw hole 34, mounting frame 31 can be limited and fixed to the surface of housing 1 and mounting plate 32.

[0029] Working principle: Before inspecting and cleaning the front fan of the harvester, first rotate the two side rings 28 to make the nuts 27 connected to them rotate. The nuts 27 then stop abutting against the connecting plate 24 and move on the screw 26 through the thread. At this time, remove the nuts 27 from the screw 26. Then pull the handle 29 to make it move the side plate 11. The side plate 11 rotates around the rotating block 22. The rotating block 22 rotates the surface of the rotating hole 23, thus exposing the slot so that the operator can enter the machine housing 1 to operate.

[0030] Before using the front fan of the harvester, first install the protective net 3 on the inner surface of the housing 1, and then attach the mounting frame 31 to the housing 1 and the mounting plate 32. Adjust the holes 33 and 34 to align them. Then, insert the screw 35 into the hole 33 and use a Phillips screwdriver to turn the screw 35 so that one end is threaded onto the screw hole 34. After tightening, the other end rests against the surface of the mounting frame 31 to complete the installation of the protective net 3, thereby preventing some of the crop residue from entering the housing 1 when it is blown away.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
