[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1 to 6 This utility model provides a seed metering and cleaning device for a seeder. The seed metering and cleaning device includes a frame 1, on which a seed metering device 3 is mounted via a first rotating shaft 2. An air duct 4 for guiding and blowing air is also provided on one side of the seed metering device 3. The device also includes:

[0035] The second rotating shaft 5 is rotatably connected to the frame 1 and is set parallel to the axis of the seed metering device 3. It is connected to the first rotating shaft 2 through the linkage mechanism 6. A transmission pin 51 is welded and fixed on the circumferential surface of the second rotating shaft 5.

[0036] The air supply mechanism 7 is installed on the second rotating shaft 5 and consists of a starter and an air supply component. The air supply component is connected to the air blowing duct 4.

[0037] It should be noted that the detailed structure and operating principle of components such as seed metering device 3 and air blowing tube 4 are described in detail in the cited document "202421145003.X", and will not be described in detail here.

[0038] A second rotating shaft 5 is also provided on the frame 1. The second rotating shaft 5 is connected to the first rotating shaft 2 through the linkage mechanism 6. Therefore, when the seed metering device 3 rotates, it can drive the second rotating shaft 5 to rotate together.

[0039] The gas supply mechanism 7 is installed on the second rotating shaft 5. Its starter is connected to the second rotating shaft 5 for transmission. Therefore, when the second rotating shaft 5 rotates, it can drive the starter to run, and then continuously supply gas to the blowing duct 4 through the gas supply mechanism.

[0040] In the embodiments of this utility model, please refer to Figure 4 The linkage mechanism 6 includes a drive sprocket 61 coaxially fixed on the first rotating shaft 2 and a driven sprocket 62 coaxially fixed on the second rotating shaft 5. The drive sprocket 61 and the driven sprocket 62 are connected by a transmission chain 63.

[0041] The diameter of the driving sprocket 61 is larger than the diameter of the driven sprocket 62.

[0042] It should be noted that: for the linkage mechanism 6, its driving sprocket 61 is fixed on the first rotating shaft 2, and the driven sprocket 62 is fixed on the second rotating shaft 5. The two are connected by a transmission chain 63. Therefore, when the first rotating shaft 2 rotates, it can drive the second rotating shaft 5 to move and rotate. Moreover, the diameter of the driven sprocket 62 is smaller than the diameter of the driving sprocket 61. Therefore, the rotation speed of the second rotating shaft 5 will be higher, so as to increase the gas supply.

[0043] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The starting component includes a transmission cylinder 71, which is coaxially sleeved on the second rotating shaft 5 and can move along the axis of the second rotating shaft 5. A continuous, wave-shaped guide groove 72 is provided on the inner circumference of the transmission cylinder 71. A positioning slide 73 is fixed on the circumferential surface of the transmission cylinder 71, and the transmission pin 51 is slidably connected to the inside of the guide groove 72.

[0044] The air supply unit consists of two sets located at the two ends of the transmission cylinder 71. It includes an air bag 74 sleeved on the second rotating shaft 5. Both ends of the air bag 74 are fixed with a housing 75. Neither the air bag 74 nor the housing 75 is in contact with the second rotating shaft 5. One housing 75 is fixed to one end of the transmission cylinder 71, while the circumferential surface of the other housing 75 is fixed with a positioning plate 76.

[0045] An air inlet 77 is provided on a housing 75 connected to the transmission cylinder 71, and an air outlet 78 is provided on another housing 75. A hose 79 is installed on the air outlet 78, and the hose 79 is connected to the air blowing duct 4. A one-way valve is installed on both the air inlet 77 and the air outlet 78.

[0046] A light rod 710 is also fixed on one side of the frame 1. The light rod 710 is slidably connected to the positioning slide 73 and is fixedly connected to the positioning plate 76.

[0047] It should be noted that: for the air supply mechanism 7, the transmission cylinder 71 is movably mounted on the second rotating shaft 5, and has a wave-shaped guide groove 72 inside. At the same time, the transmission pin 51 slides inside the guide groove 72. Therefore, when the second rotating shaft 5 rotates, the transmission pin 51 can generate an axial force on the transmission cylinder 71 to drive the transmission cylinder 71 to reciprocate.

[0048] Airbags 74 are provided on both sides of the transmission cylinder 71. Each airbag 74 has a housing 75 at both ends. One of the housings 75 is fixed to the transmission cylinder 71. Therefore, when the transmission cylinder 71 moves, it can drive the airbag 74 to reciprocate and extend. When it extends, gas enters the airbag 74 from the air inlet 77. When it compresses, gas enters the hose 79 from the air outlet 78 and then enters the blowing duct 4 from the hose 79.

[0049] The smooth rod 710 has a positioning function for the transmission cylinder 71, enabling it to slide stably. It also serves as the mounting base for one of the housing seats 75 to ensure the stability of the entire air supply component.

[0050] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0051] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
