Description

Technical Field

[0001] This utility model relates to the field of threshing machine technology, and more specifically, to a millet harvesting and threshing machine. Background Technology

[0002] In existing technologies, firstly, the threshing process is not convenient to operate. In traditional threshing machines, the threshing process often relies on fixed mechanical structures and operating methods. Operators need to manually adjust or monitor the threshing process. In this case, the machine may produce unstable threshing results due to various factors. For large-scale operations, operators need to frequently adjust various parameters of the machine, which wastes time and increases labor costs.

[0003] Secondly, the screening and filtration of grains after threshing is also a prominent issue. In existing threshing machines, millet is mixed with other impurities. Although some threshing machines are equipped with simple screening devices, most equipment cannot efficiently filter and clean the threshed grains, especially in high humidity or when there are many impurities, making it difficult to guarantee the quality of the threshed grains.

[0004] Finally, the dust generated during the threshing process also seriously affects the use of the equipment and the cleanliness of the environment. When the threshing machine is working, a large amount of dust is generated due to the high-speed rotating thresher and air flow. This dust not only causes wear and tear on the parts of the equipment, but also poses a threat to the health of the operators. Especially in dry weather conditions, the dust generation is more obvious. Most existing threshing machines do not have an effective dust emission system or dust collection device.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a millet harvester and threshing machine, which has the following beneficial effects: 1. The rotation of the stirring rod drives the connecting frame and connecting plate to flip, allowing the millet to be fully stirred and impacted during high-speed rotation, improving threshing efficiency and reducing grain loss. The flipping plates on the connecting plate generate additional turning and knocking action on the millet during rotation, further enhancing the threshing effect and making it easier to separate the grains from the husks, thus improving threshing quality. The motor drives the drive wheel, which is connected to the driven wheel through a transmission belt, achieving stable power transmission, reducing mechanical friction, and extending the service life of the equipment.

[0018] 2. Driven by the first motor, the filter plate continuously vibrates, allowing fine grains to pass smoothly through the screen, while plumper grains remain in the moving frame, thus automatically completing the grain screening and improving screening efficiency. The filter plate is installed on a sliding moving frame, which can flexibly adjust the screening position to adapt to grains of different sizes, improving applicability. The motor-driven screening process makes the millet screening more uniform, reducing the workload of manual screening and improving production efficiency.

[0019] 3. The rotation of the fan blades drives the airflow, blowing out the dust generated during the threshing process, reducing dust accumulation, improving the working environment, and reducing the impact on the health of operators. Under the action of wind, the residue inside the threshing cylinder can be cleaned in time, avoiding equipment blockage caused by the accumulation of chaff and impurities, and improving equipment stability. The opening design of the rotating door can quickly discharge the internal residual impurities, reduce maintenance difficulty, and make equipment cleaning more convenient.

[0025] Please see Figures 1-5 A millet harvester and threshing machine includes a mobile carriage 1, on which a threshing assembly is mounted. The threshing assembly includes a threshing cylinder 2, a second motor 3, a drive wheel 4, a driven wheel 5, and a transmission belt 6. The threshing cylinder 2 is mounted on the mobile carriage 1, the second motor 3 is fixedly mounted on the mobile carriage 1, the drive wheel 4 is connected to the output end of the second motor 3, the driven wheel 5 is rotatably connected to the threshing cylinder 2, and the transmission belt 6 drivesly connects the drive wheel 4 and the driven wheel 5. One end of the mobile carriage 1 is mounted on a filtering assembly, which includes a fixed frame 7, a movable frame 8, and a filter plate 9. The fixed frame 7 is mounted on the mobile carriage 1, the movable frame 8 is slidably connected to the fixed frame 7, and the filter plate 9 is mounted on the movable frame 8.

[0026] A stirring rod 10 is connected to the driven wheel 5, a connecting frame 11 is evenly connected to the stirring rod 10, and a connecting plate 12 is evenly installed on the connecting frame 11.

[0027] Connecting rods 13 are evenly installed on the connecting plate 12, and flip plates 14 are installed on the connecting plate 12.

[0028] A first motor 15 is installed on the fixed frame 7, and a rotating wheel 16 is connected to the output end of the first motor 15.

[0029] A rotating rod 17 is rotatably connected to the rotating wheel 16, and a moving block 18 is connected to one end of the moving frame 8. The moving block 18 is rotatably connected to one end of the rotating rod 17.

[0030] In this embodiment, during use, the push handle 23 is used to move the moving cart 1 to a suitable position, and the support frame 20 and support legs 21 at its bottom are used to fix it. Then, millet is injected into the threshing cylinder 2 through the feed inlet 24. Next, the second motor 3 is started, causing the output drive wheel 4 to rotate. During this rotation, the drive belt 6 drives the driven wheel 5 at one end to rotate, thus rotating the stirring rod 10. This rotation also causes the multiple connecting frames 11 to rotate, causing the connecting plates 12 to flip, and the connecting rods 13 facilitate the threshing process of the millet. The threshing process of the millet is completed by using the flip plate 14 at one end. After threshing, the millet falls into the baffle 26 through the filter screen 28 and then onto the inclined plate 27. Finally, it falls into the moving frame 8. At this time, the first motor 15 is started, which drives the rotating wheel 16 to rotate. During the rotation, the rotating rod 17 connected to it rotates continuously, which causes the moving block 18 connected to it to slide along one end of the fixed frame 7. This causes the moving frame 8 of the fixed frame 7 to slide, which causes the filter plate 9 on it to shake continuously, so that the small millet falls down along the filter plate 9, while some of the fuller millet flows down.

[0031] Please see Figure 3 As an embodiment of a millet harvester and thresher with a blowing component: a blowing component is provided on the thresher cylinder 2. The blowing component includes a rotating door 19, a support frame 20 and a support leg 21. The rotating door 19 is rotatably connected to one end of the thresher cylinder 2. The support frame 20 is set at the bottom of the mobile vehicle 1. The support leg 21 is detachably installed on the support frame 20.

[0032] The mobile cart 1 is equipped with moving wheels 22 and a push handle 23, and the threshing cylinder 2 has a feed inlet 24.

[0033] One end of the drive wheel 4 is connected to a fan blade 25, and a baffle 26 and an inclined plate 27 are installed inside the threshing cylinder 2. A filter screen 28 is installed on the inner side of the threshing cylinder 2.

[0034] More specifically, when using the threshing cylinder 2, the rotating door 19 is opened by rotating along the threshing cylinder 2, and when the second motor 3 drives the drive wheel 4, it drives the fan blade 25 on it to rotate, so that it continuously drives the airflow process, thereby blowing the dust out along one end, thus completing the treatment process of the residue on its surface.

[0035] In summary, during the use or operation of the overall equipment: During use, the push handle 23 is used to move the moving cart 1 to a suitable position, and the support frame 20 and support legs 21 at its bottom are used to fix it in place. Then, millet is injected into the threshing cylinder 2 through the feed inlet 24. Next, the second motor 3 is started, causing the output drive wheel 4 to rotate. During this rotation, the drive belt 6 drives the driven wheel 5 at one end to rotate, thus rotating the stirring rod 10. This rotation causes the multiple connecting frames 11 to rotate, causing the connecting plates 12 to flip, and the connecting rods 13 facilitate the threshing of the millet. The process involves using a rotating plate 14 at one end to thresh the millet. After threshing, the millet is filtered through a filter screen 28 and falls onto a baffle 26, then onto an inclined plate 27, and finally onto a moving frame 8. At this point, the first motor 15 is started, causing the rotating wheel 16 on it to rotate. During this rotation, the rotating rod 17 connected to it rotates continuously, causing the moving block 18 connected to it at one end to slide along one end of the fixed frame 7. This causes the moving frame 8 of the fixed frame 7 to slide, causing the filter plate 9 on it to shake continuously, thus causing the small millet to fall along the filter plate 9, while some of the fuller millet flows down.

[0036] When using the threshing cylinder 2, the rotating door 19 is opened by rotating along the threshing cylinder 2, and when the second motor 3 drives the drive wheel 4, it drives the fan blade 25 on it to rotate, which continuously drives the airflow process, thereby blowing the dust out along one end, thus completing the treatment process of the residue on its surface.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
