[0003] Announcement No.: CN 220986701 U discloses a harvester with a filtering mechanism. This solution transports wheat to a stripping platform via a harvesting mechanism and a transport mechanism. The wheat is stripped by the rotation of a first stripping shaft and a second stripping shaft, causing the wheat to fall above the filter holes. However, during use, the wheat is filtered above the inclined plate by the up-and-down movement of one side of the filter plate. During the upward movement of one side of the filter plate, the wheat is prone to slide from the top of the filter plate to the right side and fall outside the device, resulting in resource waste and greatly reducing the filtering effect of the device.
[0004] Therefore, it is necessary to provide a harvester with a filtration mechanism to solve the above-mentioned technical problems. Utility Model Content

Movable plates 34 are fixedly installed on the surfaces of the two moving blocks 32 located on the same side. A protective plate 35 is fixedly installed on the bottom of the filter plate 31 near the left side.
[0024] During use, the peeling component 20 peels the wheat ears from the wheat stalks, causing the wheat to fall onto the top of the filter plate 31. The filter plate 31 then filters the wheat. The protective plate 35 slides up and down inside the left guide plate 50 to prevent the filtered wheat from falling to the ground from the second discharge port 25.

The rotating rod 41 drives the cam 42 to rotate, and the cam 42 drives the moving plate 34 to move up and down. The moving plate 34 drives the moving block 32 to move up and down reciprocally inside the moving groove 33. At the same time, the moving block 32 drives the movable rod 43 to slide up and down in the movable hole 44. Through the action of the elastic element 45, the up and down reciprocating movement of the moving block 32 is made more stable. The moving block 32 drives the filter plate 31 to shake up and down to filter wheat, thereby improving the wheat filtration efficiency.
[0027] The stripping assembly 20 includes a transport roller 21 located inside the harvester body 10 near the left side, a stripping platform 22 located inside the harvester body 10 and at the bottom of the transport roller 21, two stripping rollers 23 located inside the harvester body 10 and at the right side of the transport roller 21, a first discharge port 24 located inside the harvester body 10 and at the right side of the stripping rollers 23, and a second discharge port 25 located at the bottom inside the harvester body 10 near the left side.

[0030] The harvester body 10 has a control room 80 on top, and two crossbeams are fixedly installed on the left side of the harvester body 10. A cutting shaft 90 is rotatably installed between the crossbeams.
[0031] Both the front and rear sides of the harvester body 10 are rotatably equipped with driven rods 46. One end of each driven rod 46 is fixedly connected to the adjacent part of the transport roller 21. The outer edge of the driven rod 46 and the outer edge of the rotating rod 41 are respectively fitted with a first grooved wheel 47 and a second grooved wheel 48. The outer edges of the first grooved wheel 47 and the second grooved wheel 48 located on the same side are both fitted with a belt 49 and are connected by transmission through the belt 49.
[0032] The working principle of the harvester with a filtration mechanism provided by this utility model is as follows:
[0033] Step 1: During use, the worker uses the peeling component 20 to peel the wheat ears from the wheat stalks, separating the wheat and placing it on top of the filter plate 31. Simultaneously, the transport roller 21 drives the driven rod 46 to rotate. The driven rod 46, through the transmission connection of the first grooved wheel 47, the second grooved wheel 48, and the belt 49, drives the rotating rod 41 to rotate. The rotating rod 41 drives the cam 42 to rotate, and the cam 42 drives the moving plate 34 to move up and down. The moving plate 34 drives the moving block 32 to reciprocate up and down inside the moving groove 33. Simultaneously, the moving block 32 drives the movable rod 43 to slide up and down in the movable hole 44. Through the action of the elastic element 45, the moving block 32 moves up and down more stably. The moving block 32 drives the filter plate 31 to shake up and down to filter the wheat, improving the wheat filtration efficiency. The protective plate 35 slides up and down inside the left guide plate 50 to prevent the filtered wheat from falling to the ground from the second discharge port 25. With the combined action of the protective plate 35 and the guide plate 50, the filtered wheat is concentrated inside the groove and discharged from the discharge hole through the discharge roller 60.
[0034] Compared with related technologies, the harvester with a filtering mechanism provided by this utility model has the following beneficial effects:
[0035] The various components of the device work together to rotate the rotating rod 41, which in turn drives the cam 42 to rotate. The cam 42 then drives the moving plate 34 to move up and down. The moving plate 34 drives the moving block 32 to move up and down reciprocally inside the moving groove 33. At the same time, the moving block 32 drives the movable rod 43 to slide up and down in the movable hole 44. The elastic element 45 makes the up-and-down reciprocating movement of the moving block 32 more stable. The moving block 32 drives the filter plate 31 to shake up and down to filter the wheat, improving the wheat filtration efficiency. With the help of the protective plate 35 and the guide plate 50, the filtered wheat is prevented from falling to the ground from the second discharge port 25, thus effectively ensuring the practicality and filtration effect of the device.
