Dust removal devices are connected to both the material-unloading opening and the discharge port.

[0004] Existing technologies often have the following drawbacks: When there is little grain on the ground, the unloading unloader may also move the grain, which is not conducive to unloading the remaining grain on the ground and reduces the efficiency of grain unloading.

[0005] Therefore, this utility model provides a grain unloading machine. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies that make it inconvenient to unload residual grain on the ground, and to propose a grain unloading machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a grain unloading machine, comprising a frame, wherein a grain unloading machine body is fixedly installed on the inner side of the frame, and a sweeping structure is provided on the lower side of the grain unloading machine body. The sweeping structure includes two connecting pins fixedly connected to both sides of the grain unloading machine body, and a rotating frame is rotatably connected to the sidewalls of the two connecting pins. The rotating frame has an H-shaped structure, and a rotating shaft is rotatably connected to the inner side of the rotating frame away from the connecting pins. A plurality of bristles are fixedly connected in a circumferential array on the sidewall of the rotating shaft.

[0008] The effect achieved by the above components is as follows: by setting up a sweeping structure and setting up bristles to sweep the residual grain on the ground, the residual grain is swept into the inside of the unloading grain unloader for collection, which improves the collection efficiency of residual grain on the ground to a certain extent and improves the performance of the unloading grain unloader.

[0029] Reference Figure 1As shown, this utility model provides a technical solution: a grain unloading machine, including a frame 1, a grain unloader body 2 fixedly installed on the inner side of the frame 1, a sweeping structure 3 provided on the lower side of the grain unloader body 2, and a combing structure 4 provided on the surface of the rotating frame 301.

[0030] The following section will explain the specific settings and functions of its sweeping structure 3 and combing structure 4.

[0031] Reference Figures 1-4 As shown in this embodiment: the sweeping structure 3 includes two connecting pins 305 fixedly connected to both sides of the unloading machine body 2. A rotating frame 301 is rotatably connected to the side walls of the two connecting pins 305. The rotating frame 301 has an H-shaped structure. A rotating shaft 302 is rotatably connected to the inner side of the rotating frame 301 away from the connecting pins 305. Several brush bristles 303 are fixedly connected to the side wall of the rotating shaft 302 in a circumferential array. By setting the sweeping structure 3 and the brush bristles 303, the residual grain on the ground is swept and collected inside the unloading machine, which improves the collection efficiency of residual grain on the ground to a certain extent and enhances the performance of the unloading machine. A motor 304 is fixedly connected to the side wall of the rotating frame 301, and the output end of the motor 304 is fixedly connected to the rotating shaft 302. When the motor 304 is started, its output end drives the rotating shaft 302 to rotate. A limiting ring 309 is fixedly connected to the other side of the rotating frame 301. The limiting ring 309 is located outside the rotating shaft 302, and a roller 310 is rotatably connected to the side wall of the limiting ring 309. The roller 310 rotatably connected to the side wall of the limiting ring 309 contacts the ground when the equipment moves. A positioning block 307 is fixedly connected to the side wall of the connecting pin 305, and a bolt 308 is threaded into the internal part of the positioning block 307. The angle of the rotating frame 301 is fixed by the cooperation of the positioning block 307 and the bolt 308. Several insertion holes 306 are opened on the surface of the rotating frame 301. The insertion holes 306 are arranged in a circumferential array around the connecting pin 305, and the size of the insertion holes 306 is adapted to the size of the bolt 308. The bolt 308 is screwed into the insertion hole 306 at the corresponding position on the surface of the rotating frame 301.

[0032] Reference Figures 1-3As shown, specifically, the combing structure 4 includes a groove 41 formed on the side wall of the rotating frame 301. A slide bar 42 is slidably connected to the inner side of the groove 41. Several combing strips 43 are fixedly connected to the surface of the slide bar 42. The combing strips 43 are slidably connected inside the rotating frame 301 and have a J-shaped structure. By setting the combing structure 4, the push of the slide bar 42 facilitates the flexible push of the combing strips 43, allowing them to be inserted between the bristles 303, thus facilitating the flexible combing of the bristles 303 and preventing grains from getting stuck between the bristles 303 and being difficult to remove. A connecting block 44 is fixedly connected to the side wall of the rotating frame 301. A drive rod 45 is threadedly connected inside the connecting block 44, and the drive rod 45 is rotatably connected to the slide bar 42. Since the drive rod 45 is rotatably connected to the slide bar 42, and the slide bar 42 is slidably connected in the groove 41 on the side wall of the rotating frame 301, the rotation of the drive rod 45 is converted into a pushing or pulling force on the slide bar 42.

[0033] Working principle: First, according to actual operational needs, the angle of the rotating frame 301 is adjusted to adapt to different ground conditions. Specifically, loosen the bolt 308 on the positioning block 307, rotate the rotating frame 301 to the appropriate angle, and then screw the bolt 308 into the corresponding insertion hole 306 on the surface of the rotating frame 301. The angle of the rotating frame 301 is fixed by the cooperation of the positioning block 307 and the bolt 308. Then, start the motor 304. The output end of the motor 304 drives the rotating shaft 302 to rotate. The bristles 303 arranged in a circular array on the side wall of the rotating shaft 302 rotate together with the rotating shaft 302. During the process, the bristles 303 sweep the residual grain on the ground, drawing it into the inside of the unloading grain unloader for collection and transport by the unloader body 2. This effectively solves the problem of difficult-to-clean residual grain on the ground. Simultaneously, the limiting ring 309 on the other side of the rotating frame 301 provides a certain limit to the rotating shaft 302, preventing it from shifting during rotation. The roller 310, rotatably connected to the side wall of the limiting ring 309, contacts the ground when the equipment moves, reducing friction between the rotating frame 301 and the ground, making the equipment move more smoothly. After lifting the rotating frame 301... Inserting the rotating bolt 308 into the corresponding socket 306 fixes the lifted rotating frame 301, preventing it from hindering grain removal when there is a lot of grain on the ground. This improves the flexibility of the sweeping structure 3. When it is necessary to comb the bristles 303 to prevent grain from getting stuck, the combing structure 4 starts working. Rotating the drive rod 45 inside the connecting block 44, since the drive rod 45 is rotatably connected to the slide bar 42 and the slide bar 42 is slidably connected in the groove 41 on the side wall of the rotating frame 301, the rotation of the drive rod 45 will be converted into the rotation of the slide bar 42. The pushing or pulling force of the strip 42 causes the slide strip 42 to slide along the slide groove 41. The combing strip 43, which is fixedly connected to the surface of the slide strip 42, moves together with the slide strip 42. The J-shaped combing strip 43 is inserted between the bristles 303 and combs the bristles 303 under the action of the slide strip 42, cleaning out the grain stuck between the bristles 303 and ensuring the normal working condition of the bristles 303. Through the synergistic effect of the sweeping structure 3 and the combing structure 4, this unloading grain unloader not only improves the collection efficiency of residual grain on the ground, but also maintains the good working condition of the bristles 303, thus improving the overall performance of the equipment.
