Description

Technical Field

[0001] This utility model belongs to the technical field of simultaneous seeding of medicinal herbs, and specifically relates to a device for simultaneous seeding of medicinal herbs. Background Technology

[0002] Seed-pesticide co-seeding machines target crop seeds. Based on the sowing method, they can be divided into three categories: row seeders, hill seeders, and broadcast seeders. These machines are typically mounted behind a tractor and are pulled by the tractor to complete the seed-pesticide co-seeding action. Existing seed-pesticide co-seeding machines simultaneously apply fertilizer during seed-pesticide co-seeding. However, seeds are generally treated with pesticides before co-seeding. Currently, pesticide treatments on the market include seed coating, seed dressing, and co-seeding of granules with crop seeds and fertilizers. Seed coating is the most common method. Seed coating and seed dressing have limited pesticide dosages, and granules have a short effective period, thus failing to effectively control pests and diseases in crop seedlings. Co-seeding of crop seeds and fertilizers with pesticides can also lead to uneven application of granules in the field due to differences in particle shape, specific gravity, and size between granules and fertilizers, causing them to stray far from the seeds and affecting their effectiveness in controlling pests in crop seedlings. The existing pesticide seed-planting machine is a two-row pesticide seed-planting machine with one granule precision planter, which distributes the pesticide to two furrow openers through a Y-shaped tube. In field operation, this often results in uneven distribution of granules between the two furrow openers, affecting the control effect of granules on major pests in the seedling stage of crops. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for simultaneous sowing of seeds and granules, which ensures that seeds and granules are sown synchronously, evenly and mixed, and extends the effective period of granules against crop seedling pests after seed sowing.

Detailed Implementation

[0028] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0029] like Figures 1-2 As shown, this utility model discloses a seed and pesticide co-sowing device, including a frame 6 and a seed and pesticide co-sowing mechanism 3. The seed and pesticide co-sowing mechanism 3 includes a seed box 12 and a pesticide box 13 arranged side by side on the frame 6. Seeds and granules are stored separately. A precision seeder 14 is connected to the lower side of both the seed box 12 and the pesticide box 13. A seed and pesticide co-sowing furrow opener 18 is arranged below the precision seeder 14, and the precision seeder 14 below the seed box 12 and the pesticide box 13 are connected to the seed and pesticide co-sowing furrow opener 18. Seed box 12 is connected to seed and pesticide sowing furrow opener 18 through seed pipe 20, and pesticide box 13 is connected to seed and pesticide sowing furrow opener 18 through pesticide pipe 19. All precision sowers 14 rotate synchronously. When precision sowers 14 rotate, seeds and granules fall simultaneously into seed and pesticide sowing furrow opener 18, and then mix together and fall into the rear of seed and pesticide sowing furrow opener 18. A soil-removing mechanism is set on the rear side of seed and pesticide sowing furrow opener 18 to remove soil, so as to realize precise, simultaneous, uniform and mixed sowing of seeds and granules.

[0030] This equipment also includes a fertilizer bin 7 mounted on a frame 6. A traction mechanism is connected to the front end of the frame 6, and a support wheel 23 is mounted on the lower side of the frame 6. The traction mechanism pulls and drives the equipment to move along the desired sowing position. The fertilizer bin 7 is fixedly mounted at one end of the frame 6 near the traction mechanism. Fertilizer is stored in the fertilizer bin 7. A fertilizer applicator 9 is mounted below the fertilizer bin 7. The upper end of the fertilizer applicator 9 is fixedly mounted on the frame 6. At least one feed roller 11 is mounted on the lower side of the fertilizer bin 7. The feed roller 11 is connected to the fertilizer applicator 9 through a fertilizer pipe 10, which is a flexible hose. The fertilizer bin 7, the feed roller 11, and the fertilizer applicator 9 constitute the fertilization mechanism 2. The feed roller 11 moves to make the fertilizer fall and fall along the flexible hose to the rear of the fertilizer applicator 9. Here, "rear" refers to the rear of the equipment in the direction of travel. The pesticide and seed sowing mechanism 3 is located behind the fertilization mechanism 3. Sowing is carried out after fertilization is completed.

[0031] like Figures 3-4 As shown, in this embodiment, the seed and pesticide sowing mechanism 3 includes two sets of seed boxes 12 and pesticide boxes 13 arranged side by side. Each of the two sets of seed boxes 12 and pesticide boxes 13 is provided with a seed and pesticide sowing furrow opener 18, which means that two rows of seeds can be sown at the same time. Correspondingly, two feed rollers 11 and two fertilizer furrow openers 9 are also provided on the lower side of the fertilizer bin 7. The two feed rollers 11 and the two fertilizer furrow openers 9 are arranged side by side at intervals below the fertilizer bin 7. The two feed rollers 11 respectively feed fertilizer to the back of the two fertilizer furrow openers 9. Then, both sets of seed boxes 12 and pesticide boxes 13 simultaneously sow seeds and granules in two alternate rows.

[0032] The soil-removing mechanism is a soil-removing claw 21. The seed-medicine co-sowing mechanism 3 also includes a pressure wheel 24 and a seed-removing disc 25. The soil-removing claw 21 is located at the end of the seed-medicine co-sowing furrow opener 18 away from the fertilizer bin 7. The pressure wheel 24 is connected to the frame 6 and is located behind the seed-medicine co-sowing furrow opener 18. There are two pressure wheels 24. The seed-removing disc 25 is also connected to the frame 6 and is located on the outer side behind the pressure wheel 24. Both seed-removing discs 25 are located on the outer side. When the seeds fall behind the seed-medicine co-sowing furrow opener 18, the soil-removing claw 21 initially removes soil to cover the fallen seeds. Then the pressure wheel 24 presses over the seeds and presses them into the soil. Then the seed-removing disc 25 at the rear moves the soil on the side to the row of seeds to cover them.

[0033] In this embodiment, a drive shaft 16 is provided between the fertilizer bin 7 and the seed-planting mechanism 3. The drive shaft 16 is rotatably mounted on the frame 6. The two support wheels 23 are connected by a support shaft 35. One end of the drive shaft 16 is connected to the support wheel 23 by a synchronous chain or synchronous belt. In this embodiment, a sprocket is provided at one end of the drive shaft 16 and a sprocket is also provided at the same end of the support shaft 35. The drive shaft 16 and the support shaft 35 are connected by a drive synchronous chain 22. In this embodiment, the seed-planting shafts 15 of the four precision seeders 14 are all connected to the drive shaft 16 by a seed-planting synchronous chain 17. With this configuration, when the traction mechanism drives the equipment to move, the support wheel 23 rotates, causing the drive shaft 16 to rotate synchronously, thereby driving each precision seeder 14 to plant synchronously. In this embodiment, the precision seeder 14 adopts a spoon-wheel type precision seeder.

[0034] Each feeding wheel 11 is connected by a fertilizer application shaft 8. The fertilizer application shaft 8 drives the feeding wheel 11 to rotate, and the rotation of the feeding wheel 11 causes the fertilizer in the fertilizer bin 7 to fall. The fertilizer application shaft 8 is also connected to the drive shaft 16 through a synchronous chain or synchronous belt. Each precision seeder 14 and each feeding wheel 11 rotate synchronously, realizing the simultaneous application of fertilizer, sowing and mixing of granules for crops. There is no need to set separate power for sowing and fertilization, making the structure of this equipment simpler and more compact.

[0035] like Figure 5 As shown, this equipment also includes a drip irrigation mechanism 4, which is located behind the seed-dressing co-sowing mechanism 3. The drip irrigation mechanism 4 includes a support frame 28, a drip irrigation support roller 26, a drip irrigation tape 27, and a guide assembly. The support frame 28 is fixedly mounted on the upper side of the frame 6. The drip irrigation support roller 26 is rotatably mounted on the upper end of the support frame 28. One end of the drip irrigation tape 27 is wrapped around the drip irrigation support roller 26. The guide assembly is connected to the lower side of the frame 6. The other end of the drip irrigation tape 27 passes over the guide assembly. The drip irrigation tape 27 is provided with several drip irrigation holes, and the guide assembly is located between the two sets of seed-dressing co-sowing furrow openers 18. After the seeds are buried, the drip irrigation tape 27 is placed between the two rows of seeds. The drip irrigation tape 27 provides water to the two rows of seeds. Of course, in areas where there is no shortage of water resources, it is not necessary to bury the drip irrigation tape 27.

[0036] Specifically, the guiding assembly includes a guide frame 29 and a guide wheel 30. The upper end of the guide frame 29 is fixedly connected to the frame 6, and the guide frame 29 is located behind the seed-planting mechanism 3. The guide frame 29 is fixedly positioned between two rows of seeds. The guide wheel 30 is rotatably connected to the lower end of the guide frame 29. The other end of the drip irrigation tape 27 passes around the guide wheel 30 from the front end of the guide wheel 30. Before sowing begins, the other end of the drip irrigation tape 27 is fixed at the sowing start end. Then, the traction mechanism drives the equipment to move, and the drip irrigation tape 27 pulls the drip irrigation support roller 26 to rotate, causing the drip irrigation tape 27 to spread out from the drip irrigation support roller 26 and be buried between the two rows of seeds.

[0037] This equipment also includes a mulching mechanism 5, which is located behind the drip irrigation mechanism 4. The mulching mechanism 5 includes a mulching shaft 31, a pressing wheel 32, and a mulch film soil-removing disc 33 arranged sequentially from front to back. The mulching shaft 31 is fixedly connected to the bottom of the frame 6. The mulch film is fitted onto the mulching shaft 31. The two pressing wheels 32 and the two mulch film soil-removing discs 33 are symmetrically arranged on both sides of the frame 6, and the mulch film soil-removing discs 33 are located on the outside of the pressing wheels 32. Before sowing begins, the end of the mulch film is fixed at the sowing start end. Then, the traction mechanism drives the equipment to move. The mulch film rotates around the mulching shaft 31 and covers the two rows of seeds after sowing. The pressing wheels 32 press over both sides of the mulch film, and then the mulch film soil-removing discs 33 on both sides move the soil on the sides of the mulch film to cover and fix the mulch film.

[0038] like Figure 6 As shown, in this embodiment, the traction mechanism is a tractor 1. A connecting frame 34 is fixedly installed on the front side of the frame 6. The connecting frame 34 is hinged to the tractor 1. The tractor 1 drives the equipment to move, perform fertilization, sowing, laying drip irrigation tape 27 and mulching.

[0039] When this utility model is in use, the tractor 1 pulls the equipment along the desired sowing position. The fertilization mechanism 2 at the front first applies fertilizer, and the fertilizer furrow opener 9 first opens the furrow for fertilizer. The feed wheel 11 rotates so that the fertilizer in the fertilizer bin 7 falls into the furrow opened by the fertilizer furrow opener 9. Then, the two seed and pesticide sowing furrow openers 18 at the rear open the furrow for seeds. Each precision seeder 14 rotates together so that the seeds and granules fall simultaneously behind the seed and pesticide sowing furrow opener 18. The soil-pulling claw 21 initially pulls the soil to bury the fallen seeds. Then, the pressure wheel 24 presses over the seeds and presses them into the soil. Then, the seed soil-pulling disc 25 at the rear pulls the soil from the side onto the sowing row to bury the seeds.

[0040] In areas where drip irrigation tape 27 needs to be installed, before sowing begins, the other end of drip irrigation tape 27 is fixed to the sowing start end, and the end of the mulch film is fixed to the sowing start end. Then, the equipment moves, causing the drip irrigation tape 27 to spread out from the drip irrigation support roller 26 and be installed between the two rows of seeds. The mulch film rotates around the covering shaft 31 and covers the two rows of seeds after sowing. The pressing roller 32 presses over both sides of the mulch film, and then the mulch film soil-removing discs 33 on both sides move the soil from the sides to both sides of the mulch film to cover and fix the mulch film, thus completing the sowing. This invention enables simultaneous sowing of seeds and granules, achieving precise application, extending the effective period of granules, and effectively controlling crop seedling diseases and pests. Each precision seeder 14 and the feeding wheel 11 rotate synchronously, enabling simultaneous sowing of crop granules and seeds, fertilization, mulching, and drip irrigation. There is no need to set separate power for sowing and fertilization. The precision seeders 14 arranged side by side dissipate the seeds and granules, ensuring that the seeds and granules can be quantitatively, accurately, and evenly distributed and continuously mixed for sowing.
