[0028] Please see Figure 1-5As shown, this utility model is a seed screening device for forage sowing, including a mounting plate 1. Several mounting brackets 101 are fixedly connected to the outer wall of the mounting plate 1, and several limiting rods 102 are also fixedly connected to the outer wall of the mounting plate 1.

A turntable 205 is fixedly connected to the outer wall of the rotating shaft 203 on the side away from the first motor 202. After the first motor 202 starts, it will rotate the rotating shaft 203, and then the rotating shaft 203 will rotate the turntable 205, realizing the kinetic energy transfer between the parts. A fixing rod 206 is fixedly connected to the outer wall of the turntable 205 on the side away from the first motor 202. A connecting rod 207 is rotatably connected to the outer wall of the fixing rod 206. The inner wall of the connecting rod 207 is rotatably connected to... Regarding the joint shaft 208, when the turntable 205 rotates, it drives the fixed rod 206 to rotate. Then, the fixed rod 206 drives the connecting rod 207 to move. When the connecting rod 207 moves, it drives the joint shaft 208 to move, facilitating the transfer of kinetic energy between parts. When one part moves, other parts will also move. Several springs 209 are sleeved on the outer walls of several limit rods 102. Several annular plates 210 are slidably connected to the outer walls of several limit rods 102. A screening plate 211 is fixedly connected to the outer wall of the annular plate 210 near the connecting rod 207. A diverter plate 212 is fixedly connected to the outer wall of the screening plate 211 away from the first motor 202. When the forage seeds are placed on the screening plate 211, the screening plate 211 will filter the forage seeds, and then the forage seeds will fall onto the guide plate 213. Impurities will slide off the diversion plate 212 to other places. The guide plate 213 is fixedly connected to the outer wall of the end of the ring plate 210 near the connecting rod 207. The outer wall of the guide plate 213 is fixedly connected to the outer wall of the joint shaft 208. The outer wall of the mounting frame 101 is provided with a dust removal mechanism 3. When the joint shaft 208 moves, it will move the guide plate 213, and then the guide plate 213 will move the ring plate 210. When the ring plate 210 moves, the screening plate 211 will move along with it, improving the screening efficiency.

[0029] When the first motor 202 starts, it drives the rotating shaft 203 to rotate. Then, the rotating shaft 203 drives the turntable 205 to rotate. When the turntable 205 rotates, it drives the fixed rod 206 to rotate. Then, the fixed rod 206 drives the connecting rod 207 to move. When the connecting rod 207 moves, it drives the joint shaft 208 to move. Then, the joint shaft 208 drives the guide plate 213 to move. When the guide plate 213 moves, it drives the annular plate 210 to move. At the same time, the annular plate 210 drives the screening plate 211 to move. Then, the diverting plate 212 follows the screening plate 211 to move, thereby improving the screening efficiency and reducing the working time.

[0030] The dust removal mechanism 3 includes a feed pipe 301. The outer wall of the feed pipe 301 is fixedly connected to the outer walls of several mounting brackets 101. A groove 302 is provided on the inner wall of the feed pipe 301. A baffle 303 is slidably connected to the inner wall of the groove 302. The baffle 303 and the groove 302 are slidably connected, and the baffle 303 can maintain horizontal movement when it moves. The movement of the baffle 303 can control the amount of forage seeds fed. A ring 304 is fixedly connected to the outer wall of the end of the baffle 303 near the first motor 202. The inner wall of the mounting plate 1... The threaded connection includes a threaded rod 305, with a limit ring 306 fixedly connected to the outer wall of the threaded rod 305. The outer wall of the threaded rod 305 is rotatably connected to the inner wall of the ring 304. A ventilation pipe 307 is fixedly connected to the outer wall of the mounting bracket 101 near the connecting rod 207. When the threaded rod 305 rotates on the mounting plate, it will move, and then the threaded rod 305 will move along with the limit ring 306 and the ring 304. Then the ring 304 will move along with the baffle 303, which makes it convenient for the operator to control the discharge amount.

[0031] When the threaded rod 305 rotates, it will move, and then the threaded rod 305 will move along with the limiting ring 306 and the ring 304. Then the ring 304 will drive the baffle 303 to move. When the baffle 303 moves, it will change the output of the feed pipe 301. At the same time, the limiting ring 306 will limit the movement of the threaded rod 305 to prevent excessive movement and cause the baffle 303 to fall off.

[0032] A baffle rod 308 is rotatably connected to the inner wall of the ventilation duct 307. A concave wheel 309 is fixedly connected to the outer wall of the side of the baffle rod 308 away from the first motor 202. A fixing plate 310 is fixedly connected to the outer wall of the end of the ventilation duct 307 away from the first motor 202. When the concave wheel 309 rotates, it will cause the baffle rod 308 to rotate. When the baffle rod 308 rotates, it will change the size of the air outlet 320, which can facilitate the control of the air volume. A circular groove 311 is opened on the inner wall of the fixing plate 310. A slide rod 312 is slidably connected to the inner wall of the circular groove 311. A pressure spring 313 is sleeved on the outer wall of the slide rod 312. The pressure spring 313 will then compress the slide rod 312, so that the slide rod 312 is always stuck in the concave wheel 309 to prevent the concave wheel 309 from rotating on its own. A rolling rod 314 is rotatably connected to the inner wall of the ventilation duct 307. A roller is fixedly connected to the outer wall of the rolling rod 314. Fan 315, pulley 316 is fixedly connected to the outer wall of shaft 203, belt 317 is driven to the outer wall of pulley 316. When shaft 203 rotates, it drives pulley 316 to rotate. Then pulley 316 drives pulley disc 318 to rotate through belt 317, realizing the kinetic energy transfer between parts. When one part moves, other parts will also move. The outer wall of rolling rod 314 near the first motor 202 is fixedly connected to pulley disc 318. The outer wall of pulley disc 318 is driven to the inner wall of belt 317. Ventilation pipe 307 has an air inlet 319 and an air outlet 320 on its inner wall. When pulley disc 318 rotates, it drives rolling rod 314 to rotate. Then rolling rod 314 drives roller fan 315 to rotate. When roller fan 315 rotates, it blows the grass seeds to reduce the presence of dust and grass shells.

[0033] Pulling the slide bar 312 will compress the pressure spring 313 as it moves, causing the concave wheel 309 to rotate. As the concave wheel 309 rotates, the wind deflector 308 will also rotate. Then, releasing the slide bar 312 will cause the pressure spring 313 to compress the slide bar 312, causing it to engage with the concave wheel 309. Simultaneously, as the rotating shaft 203 rotates, it will cause the pulley 316 to rotate. The pulley 316 then drives the pulley disc 318 to rotate via the belt 317. As the pulley disc 318 rotates, it will cause the rolling rod 314 to rotate. The rolling rod 314 then drives the drum fan 315 to rotate. When the drum fan 315 rotates, it will blow away the falling grass seeds, reducing the presence of dust and grass husks.

[0034] One specific application of this embodiment is:

[0035] When the operator needs to use the equipment, firstly, the first motor 202 is started. Then, the forage seeds are put into the feed pipe 301. At the same time, the threaded rod 305 can be rotated. As the threaded rod 305 rotates, it moves, and the ring 304 and the limiting ring 306 move with the threaded rod 305. When the ring 304 moves, the baffle 303 moves with it. Then, the baffle 303 changes the size of the outlet of the feed pipe 301, making it easier to control the output of the forage seeds. Then, the forage seeds will slide from the feed pipe 301 onto the screening plate 211. At the same time, after the first motor 202 is started, it will carry the rotating rod 211 along with the forage seeds. When shaft 203 rotates, pulley 316 rotates along with it. As pulley 316 rotates, belt 317 drives pulley 318 to rotate, and roller 314 rotates with pulley 318. When roller 314 rotates, drum fan 315 rotates as well, blowing air onto the hay seeds to reduce dust and chaff. Simultaneously, it pulls slide bar 312, which compresses pressure spring 313, rotating concave wheel 309. As concave wheel 309 rotates, windbreak bar 308... As the wind deflector 308 rotates, the airflow changes. Once the airflow is appropriate, the slide bar 312 is released, and then the pressure spring 313 presses against the slide bar 312. The slide bar 312 moves as it is pressed, and then it engages with the concave wheel 309, preventing the concave wheel 309 from rotating on its own. Simultaneously, the rotation of the rotating shaft 203 causes the turntable 205 to rotate, which in turn causes the fixed rod 206 to rotate. The rotation of the fixed rod 206 causes the connecting rod 207 to move, and the joint shaft 208 moves along with the connecting rod 207. When the device moves, it will push the guide plate 213 to move. When the guide plate 213 moves, the annular plate 210 will move along with it. During the movement of the annular plate 210, the spring 209 will be squeezed, and the spring 209 will reduce the vibration caused by the movement. Then, when the annular plate 210 moves, the screening plate 211 will move along with it. When the screening plate 211 moves, the diversion plate 212 will move along with it. Then the screening plate 211 will screen the forage seeds. During the screening process, the forage seeds will fall onto the guide plate 213 and be discharged. Then other impurities will slide onto the diversion plate 212 and be discharged, thus separating the impurities from the forage seeds.
