Description

Technical Field

[0001] This utility model relates to the field of air suction seeders, specifically an electrically controlled fan air suction seeder. Background Technology

[0002] The electrically controlled blower-driven air suction seeder is a modern agricultural machine that combines electronic control technology with the principle of air suction seeding to achieve efficient and precise seeding operations. The working principle of the electrically controlled blower-driven air suction seeder is based on the principle of negative pressure adsorption of seeds. When the seeder is working, the high-speed blower generates negative pressure and transmits this negative pressure to the vacuum chamber of the seed metering unit. During the rotation of the seed metering disc, the negative pressure in the vacuum chamber adsorbs the seeds, causing them to rotate with the seed metering disc. When the seeds rotate out of the vacuum chamber, since they are no longer under negative pressure, they will fall into the soil by their own weight or under the action of the seed scraper, thus completing the seeding.

[0003] Since the electric control fan needs to be connected to the seed metering device through a connecting pipe, most electric control fans are connected to the crossbeam of the air suction seeder by bolts. When the bolts are exposed to the outside for a long time and weather, they are prone to rust, making it inconvenient to disassemble and repair the electric control fan. Therefore, an electric control fan air suction seeder is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrically controlled fan air suction seeder, which has advantages such as easy disassembly of the electrically controlled fan. It solves the problem that since the electrically controlled fan needs to be connected to the seed metering device through a connecting pipe, most electrically controlled fans are connected to the crossbeam of the air suction seeder by bolts. When the bolts are exposed to the outside for a long time and weather, they are prone to rust, making it difficult to disassemble and repair the electrically controlled fan.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrically controlled fan air suction seeder, comprising a seeder body, wherein an electrically controlled fan body is disposed inside the seeder body, a shock-absorbing structure is disposed at the bottom of the electrically controlled fan body, and a connecting structure is disposed at the bottom of the shock-absorbing structure;

[0006] The damping structure includes a connecting plate, a connecting plate fixedly installed at the bottom of the electric fan body, a damper fixedly installed at the bottom of the connecting plate, a hinge rod hinged to the bottom of the connecting plate, a push plate hinged to the bottom of the hinge rod, a push rod fixedly installed on the outside of the push plate, a spring sleeved on the outside of the push rod, a support block fixedly installed at the bottom of the damper, and an mounting plate fixedly installed at the bottom of the support block.

[0007] The connecting structure includes a locking block. The locking block is fixedly installed on the bottom of the mounting plate. A movable block is locked inside the locking block. A movable rod is fixedly installed outside the movable block. An adjusting rod is fixedly installed inside the movable rod. A worm gear is fixedly installed outside the adjusting rod. A mounting box is rotatably installed outside the adjusting rod. A rotating rod is rotatably installed inside the mounting box. A worm gear is fixedly installed outside the rotating rod.

[0008] Furthermore, the push rod passes through the support block and is movably connected to the support block, and the end of the spring away from the push plate is fixedly connected to the support block.

[0009] Furthermore, the rotating rod passes through the mounting box and extends to the outside of the mounting box, and the worm gear meshes with the worm wheel.

[0010] Furthermore, the movable rod passes through the mounting box and extends to the outside of the mounting box, and the adjusting rod passes through the movable rod and is fixedly connected to the movable rod.

[0011] Furthermore, the adjusting rod passes through the worm gear and is fixedly connected to the worm gear, and both ends of the adjusting rod are rotatably connected to the inner wall of the mounting box.

[0012] Furthermore, the moving block passes through the locking block and engages with it, and the locking slots of the two locking blocks are distributed in opposite directions.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This electrically controlled blower air suction seeder works by attaching the bottom of the mounting plate to the crossbeam of the air suction seeder. Rotating the rotating rod drives the worm gear to rotate, which in turn moves the movable rod and causes the movable block to engage with the locking block. The movable block and locking block fix the mounting box and mounting plate to the outside of the crossbeam. When the air suction seeder is sowing, vibration is inevitable. The damper can effectively reduce the vibration of the electrically controlled blower body and prevent the vibration of the air suction seeder from damaging the electrically controlled blower body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 An electrically controlled fan air suction seeder in this embodiment includes a seeder body 1, an electrically controlled fan body 2 is provided inside the seeder body 1, a shock-absorbing structure 3 is provided at the bottom of the electrically controlled fan body 2, and a connecting structure 4 is provided at the bottom of the shock-absorbing structure 3.

[0021] The damping structure 3 includes a connecting plate 301. The connecting plate 301 is fixedly installed at the bottom of the electric fan body 2. A damper 302 is fixedly installed at the bottom of the connecting plate 301. A hinge rod 303 is hinged to the bottom of the connecting plate 301. A push plate 304 is hinged to the bottom of the hinge rod 303. A push rod 305 is fixedly installed on the outside of the push plate 304. A spring 306 is sleeved on the outside of the push rod 305. A support block 307 is fixedly installed at the bottom of the damper 302. An mounting plate 308 is fixedly installed at the bottom of the support block 307.

[0022] The connecting structure 4 includes a locking block 401. The locking block 401 is fixedly installed on the bottom of the mounting plate 308. A movable block 402 is locked inside the locking block 401. A movable rod 403 is fixedly installed outside the movable block 402. An adjusting rod 404 is fixedly installed inside the movable rod 403. A worm gear 405 is fixedly installed outside the adjusting rod 404. A mounting box 406 is rotatably installed outside the adjusting rod 404. A rotating rod 407 is rotatably installed inside the mounting box 406. A worm gear 408 is fixedly installed outside the rotating rod 407.

[0023] exist Figure 3In the middle, the locking block 401 is located on the left and right sides of the bottom of the mounting plate 308. By moving the movable rod 403, the movable block 402 can be driven to engage with the locking block 401, so that the bottom of the mounting plate 308, the top of the mounting box 406, and the side of the two movable rods 403 that are close to each other are all in contact with the crossbeam.

[0024] exist Figure 2 In the process, the connection between the hinge rod 303 and the push plate 304 causes the connecting plate 301 to float up and down when it is subjected to vibration, thereby causing the hinge rod 303 to push the push plate 304.

[0025] exist Figure 2 When the push plate 304 moves, it will compress the spring 306. When the damper 302 reduces the vibration of the connecting plate 301, the spring 306 will rebound and drive the connecting plate 301 to reset.

[0026] During implementation, follow these steps: When in use, align the bottom of the mounting plate 308 with the top of the crossbeam, and align the top of the mounting box 406 with the bottom of the crossbeam. Then rotate the adjusting rod 404 to fix the position of the mounting plate 308, thus connecting the electric fan body 2 and the crossbeam.

[0027] In summary, this electrically controlled blower air suction seeder, after the bottom of the mounting plate 308 is attached to the crossbeam of the air suction seeder, rotating the rotating rod 407 will drive the worm gear 408 to rotate, thereby moving the movable rod 403 and causing the movable block 402 to engage with the locking block 401. The movable block 402 and the locking block 401 fix the mounting box 406 and the mounting plate 308 to the outside of the crossbeam. When the air suction seeder is sowing, vibration is inevitable. The damper 302 can effectively reduce the vibration of the electrically controlled blower body 2, preventing the vibration of the air suction seeder from causing damage to the electrically controlled blower body 2. This solves the problem that since the electrically controlled blower needs to be connected to the seed metering device through a connecting pipe, most electrically controlled blowers are connected to the crossbeam of the air suction seeder by bolts. When the bolts are exposed to the outside for a long time and weather, they are prone to rust, making it difficult to disassemble and repair the electrically controlled blower.
