Description

Technical Field

[0001] This utility model belongs to the field of agricultural seed impurity removal technology, and in particular relates to a high-efficiency wind-separation impurity removal device for corn seeds. Background Technology

[0002] According to the published patent CN222943944U, a corn seed selection and impurity removal device includes an outer shell, a drive motor fixedly connected to the outer shell, a worm gear fixedly connected to the output end of the drive motor, a worm wheel meshing with the worm gear, a rotating column fixedly connected to the worm wheel, a stirring blade fixedly connected to the rotating column, a square hole provided on the stirring blade, a first sprocket fixedly connected to the rotating column, and a chain meshing with the first sprocket. After the above device is completed, air is drawn in from the outside by a fan. After the corn seeds enter the outer shell, they roll on the first filter plate, causing the lint mixed in with the corn seeds to be blown to the discharge port and discharged. This allows for the rapid processing of a large number of corn seeds. However, the following shortcomings still exist. After the above equipment is completed, it only blows air on the corn seeds to remove the fluff. However, it is difficult to adjust the air volume when blowing on the corn seeds, which may result in excessive air volume blowing the corn seeds away and wasting them. Therefore, we propose a high-efficiency air separation and impurity removal device for corn seeds. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency air separation and impurity removal device for corn seeds. Through the adjustment mechanism and the filtration mechanism, it solves the problem that simply blowing air onto the corn seeds to remove the lint is difficult to adjust, which leads to excessive air volume blowing away the corn seeds and wasting them.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a high-efficiency air separation and impurity removal device for corn seeds, including an impurity removal box, a material box fixedly connected to the inner wall of the impurity removal box, a trough opened in the inner wall of the material box, a discharge port opened in the inner wall of the impurity removal box, and an adjustment mechanism provided on the outer wall of the impurity removal box. The adjustment mechanism includes a controller, the outer wall of which is fixedly connected to the outer wall of the impurity removal box. A ventilation pipe is fixedly connected to the inner wall of the impurity removal box, and a crossflow fan is fixedly connected to the inner wall of the ventilation pipe. Several fixed frames are fixedly connected to the outer wall of the impurity removal box, and a worm gear is rotatably connected to the inner wall of each fixed frame. Several rotating shafts are rotatably connected to the inner wall of the ventilation pipe. A worm wheel is fixedly connected to the outer wall of the rotating shaft near the worm gear, and the outer wall of the worm wheel meshes with the outer wall of the worm gear. A baffle plate is fixedly connected to the outer wall of the rotating shaft, and an impurity removal port is opened on the inner wall of the end of the impurity removal box away from the ventilation pipe.

[0005] Furthermore, a motor frame is fixedly connected to the outer wall of the impurity removal box, and a first motor is fixedly connected to the inner wall of the motor frame. A roller is fixedly connected to the bottom output end of the first motor through a coupling. The outer wall of the roller is rotatably connected to the inner wall of the impurity removal box. A round rod is fixedly connected to the outer wall of the roller. Several round grooves are opened on the inner wall of the round rod. A filtering mechanism is provided on the outer wall of the roller.

[0006] Furthermore, the filtration mechanism includes a pulley, the inner wall of which is fixedly connected to the outer wall of the roller.

[0007] Furthermore, a belt is driven to the outer wall of the pulley, and a crankshaft is rotatably connected to the inner wall of the impurity removal box.

[0008] Furthermore, a pulley is fixedly connected to the outer wall of the crankshaft near the belt end, and the outer wall of the pulley is connected to the inner wall of the belt in a driving connection.

[0009] Furthermore, a connecting rod is rotatably connected to the outer wall of the crankshaft, and a rotating rod is fixedly connected to the inner wall of the connecting rod.

[0010] Furthermore, a connecting plate is rotatably connected to the outer wall of the rotating rod, and a fixing plate is fixedly connected to the inner wall of the impurity removal box.

[0011] Furthermore, the inner wall of the fixed plate is provided with a guide groove, the inner wall of the guide groove is slidably connected to the outer wall of the connecting plate, and a filter plate is fixedly connected to the outer wall of the end of the connecting plate away from the crankshaft.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up a round rod and a baffle plate, discharges light impurities from the corn seeds through the impurity removal port during airflow, preventing the corn seeds from containing too many light impurities. At the same time, the worm can be rotated, which in turn drives the worm wheel to rotate, and the worm wheel drives the shaft to rotate, which in turn drives the baffle plate to rotate. This improves flexibility, allowing the airflow to be adjusted according to different impurities, preventing excessive airflow from blowing away the corn seeds. It also allows for the quantitative discharge of corn seeds, preventing excessive discharge from affecting airflow and maintaining a stable impurity removal efficiency for the equipment.

[0013] 2. This utility model incorporates a crankshaft and a filter plate. When the belt pulley rotates, it drives the crankshaft to rotate as well. The crankshaft then causes the connecting rod to move in an arc shape, which in turn moves the rotating rod. As the rotating rod moves, the connecting plate slides back and forth in the guide groove. Finally, the moving connecting plate moves the filter plate, thereby increasing the quality of impurity removal. This effectively separates heavier impurities from corn seeds, preventing them from remaining as heavy impurities and resulting in purer corn seeds.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer wall of one end of the rotating shaft 205 near the worm gear 204 is fixedly connected to... There is a worm gear 206. When the worm 204 rotates, it will drive the worm gear 206 to rotate. Then, when the worm gear 206 rotates, it will drive the shaft 205 to rotate, realizing the kinetic energy transmission between the parts. The outer wall of the worm gear 206 meshes with the outer wall of the worm 204. The outer wall of the shaft 205 is fixedly connected to the baffle plate 207. The inner wall of the end of the impurity removal box 1 away from the ventilation pipe 201 has an impurity removal port 208. When the shaft 205 rotates, it will drive the baffle plate 207 to rotate. Then, when the baffle plate 207 rotates, it will change the opening in the ventilation pipe 201, which makes it easy to adjust the air volume.

[0020] A motor frame 209 is fixedly connected to the outer wall of the impurity removal box 1. A first motor 210 is fixedly connected to the inner wall of the motor frame 209. The operator starts the first motor 210 through the controller 214. A roller 211 is fixedly connected to the bottom output end of the first motor 210 through a coupling.

The inner wall of the round rod 212 has several round grooves 213. After the first motor 210 is started, it will rotate the roller 211. Roller 211 rotates along with rod 212, enabling the transfer of kinetic energy between parts. A filter mechanism 3 is provided on the outer wall of roller 211. The filter mechanism 3 includes a pulley 301. The inner wall of pulley 301 is fixedly connected to the outer wall of roller 211. A belt 302 is driven to the outer wall of pulley 301.

Then, when the filter plate 310 moves, it will separate the heavy impurities in the corn seeds.

[0022] One specific application of this embodiment is: When the operator needs to use the equipment, they first put the corn seeds into the material box 101. After the corn seeds are placed, the operator uses the controller 214 to start the crossflow fan 202 and the first motor 210. Then, after the corn seeds are placed, the corn will fall from the trough 102 into the circular trough 213. At the same time, when the first motor 210 rotates, it will drive the roller 211 to rotate. When the roller 211 rotates, it will drive the circular rod 212 to rotate. Then, when the circular rod 212 rotates, it will transport the corn seeds in the circular trough 213 to the impurity removal box 1, so that the corn seeds are transported from the circular trough 213 to the impurity removal box 1. The corn seeds fall into the bottom of the impurity removal box 1 from the trough 213. Simultaneously, a measured amount of corn seeds is conveyed to prevent excessive seed delivery from affecting the impurity removal process and to ensure stable airflow. When the crossflow fan 202 rotates, it draws outside air into the impurity removal box 1 through the ventilation pipe 201. During this airflow, light impurities in the corn seeds are discharged from the impurity removal port 208, preventing the corn seeds from containing excessive light impurities. At the same time, the worm gear 204 can be rotated, causing the worm wheel 206 to rotate, which in turn drives the shaft 20... 5. The rotation of the rotating shaft 205 causes the baffle plate 207 to rotate, which in turn alters the opening in the ventilation pipe 201, facilitating the adjustment of the equipment's ventilation volume and preventing excessive ventilation from blowing away the corn seeds. After the corn seeds have been cleaned of light impurities, they fall onto the filter plate 310. Simultaneously, the rotation of the roller 211 causes the pulley 301 to rotate, which in turn drives the belt 302 to rotate the pulley 304, which in turn drives the crankshaft 303. When the crankshaft 303 rotates, it will cause the connecting rod 305 to move in an arc. Then the connecting rod 305 will move the rotating rod 306. When the rotating rod 306 moves, it will cause the connecting plate 307 to slide back and forth in the guide groove 309. Then, when the connecting plate 307 moves, it will cause the filter plate 310 to move. When the filter plate 310 moves, it will separate the heavy impurities in the corn seeds, making the corn seeds purer. Then the corn seeds will fall to the bottom of the impurity removal box 1 after passing through the filter plate 310. At the same time, the operator can collect the corn seeds through the discharge port 103.
