[0001] This utility model relates to the technical field of agricultural production machinery, and in particular to a seed feeder that can feed two rows of seeds at once. Background Technology
[0002] To build modern agricultural production, mechanized agricultural production is an inevitable trend. Sowing plays a crucial role in modern agricultural development, as all growth and harvesting are based on sowing. With the continuous development of agricultural production technology, the requirements for agricultural machinery are also gradually increasing. Especially in sowing, agricultural machinery often needs to achieve precision sowing according to agronomic requirements to improve labor efficiency and reduce the intensity of subsequent field management.
[0003] The existing seed feeder can only feed one row of seeds. If it is necessary to feed two rows of seeds that are close together, two seed feeders are required. The spacing between the two rows needs to be adjusted according to the spacing of the planting rows, which makes the flexibility and practicality of the seed feeder low. Utility Model Content
[0004] The purpose of this invention is to provide a seed feeder that can feed two rows of seeds at once, in order to solve the problems mentioned in the background art.

Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] Given that current technology can only feed one row of seeds, if it is necessary to feed two rows of seeds that are close together, two seed feeders are required, and the spacing between the two rows needs to be adjusted according to the spacing of the planting rows, which makes the flexibility and practicality of the seed feeder low.
[0028] like Figure 1-5As shown, this utility model embodiment provides a seed dispenser that can dispense two rows of seeds at once, including a seed dispensing component 1. The seed dispensing component 1 includes: a first housing 11 with seed bins symmetrically arranged inside; a feeding port 13 symmetrically arranged on both sides of the first housing 11; a central shaft 14 penetrating through the center of the first housing 11; a seed picking plate 15 symmetrically fixed to the outside of the central shaft 14 and located inside the seed bins 12; a seed guide plate 16 symmetrically fixed to the outside of the central shaft 14 and located on one side of the seed picking plate 15, with a seed dropping hole 161 at the bottom of the outer side of the first housing 11 that matches the seed guide plate 16; a partition plate 17 disposed between the seed picking plate 15 and the seed guide plate 16, with a through groove 171 on the partition plate 17 that matches the seed picking plate 15; and a mounting plate 18 disposed on the first housing 11. An adjustment assembly 2 is provided on one side of the mounting plate 18 on the outer side of the first housing 11, and is located at the bottom of the outer side of the first housing 11. The adjustment assembly 2 includes: a bellows 21 disposed at the bottom of the seed hole 161; a guide port 22 disposed and fixed at the bottom of the bellows 21; a second housing 23 disposed and fixed on one side of the first housing 11; a bidirectional threaded rod 24 disposed inside the second housing 23 and rotatably connected to the second housing 23; a moving rod 241 disposed between the guide port 22 and the bidirectional threaded rod 24 and threadedly connected to the bidirectional threaded rod 24; a through groove 242 that mates with the moving rod 241 is provided on one side of the second housing 23; and a rotating rod 25 disposed and fixed at one end of the bidirectional threaded rod 24 and passes through the second housing 23.
[0029] In use, the first housing 11 is installed on the seeder using the mounting plate 18 and fixing bolts. Then, the central shaft 14 is rotated by the transmission device on the seeder, which in turn drives the two sets of seed guide discs 16 to rotate, simultaneously rotating the two sets of seed collection discs 15. When crop seeds enter the seed chamber 12 through the feeding port 13, the two sets of seed collection discs 15, designed with seed collection structures, continuously scoop up seeds from the two seed chambers. When they reach their highest point, the seeds pass through the through-slot 171 left by the partition plate 17 into the rotating seed guide disc 16. The rotation of the seed guide disc 16 then carries the seeds to the lowest point of the seed feeder, allowing them to be discharged through the seed drop hole. The discharged seeds are then fed through the corrugated pipe 21 and the guide port 22, thus completing the work of feeding two rows of seeds with one seed feeder. When adjusting the seed spacing, the rotating rod 25 is rotated, which drives the bidirectional threaded rod 24 to rotate. The rotating bidirectional threaded rod 24 pushes the moving rod 241 to move towards or relative to each other. The moving rod 241, in conjunction with the bellows 21, drives the guide port 22 to move towards or relative to each other, thereby adjusting the seed spacing. This increases the convenience of adjusting the seed spacing of the seed dispenser that can dispense two rows of seeds at once, and improves the flexibility and practicality of the seed dispenser.
[0030] Furthermore, a limiting plate 243 is provided at the center of the bidirectional threaded rod 24 to cooperate with the moving rod 241, and is located inside the second housing 23 to limit the moving rod 241 and prevent it from moving onto the opposite thread when moving towards each other.
[0031] Furthermore, a rubber baffle 29 is provided at the opening of the through groove 242 to cooperate with the bidirectional threaded rod 24, thereby blocking the opening of the through groove 242 and preventing soil from entering the interior of the through groove 242 through the opening and affecting the rotation of the bidirectional threaded rod 24 and the movement of the moving rod 241.
[0032] Furthermore, the outer side of the rotating rod 25 is provided with a reverse thread 27, and a threaded sleeve 271 is provided on the reverse thread 27 and is threadedly connected to the threaded sleeve 271. When the rotating rod 25 is rotated to adjust the seeding distance of the guide port 22, the threaded sleeve 271 is rotated. The rotating threaded sleeve 271, in conjunction with the reverse thread 27, moves and presses against the outer wall of the second housing 23, thereby pressing and locking the rotating rod 25, which increases the stability after the seeding distance is adjusted.
[0033] Furthermore, a pressing plate 28 is provided on one side of the threaded sleeve 271 and is sleeved on the outside of the rotating rod 25, which increases the area of the threaded sleeve 271 pressing the outer wall of the second housing 23 and improves the stability of pressing and locking the rotating rod 25.
[0034] Furthermore, an anti-slip pad 281 is provided between the sidewalls of the extrusion plate 28 and the second housing 23, which increases the anti-slip properties of the outer sidewalls of the extrusion plate 28 and the second housing 23.
[0035] Furthermore, a locking block 26 is fitted and fixed on the top outer side of the corrugated pipe 21, and a slot 261 that matches the locking block 26 is provided on the bottom outer side of the first housing 11, so that the corrugated pipe 21 and the first housing 11 can be locked together, making it convenient to assemble and disassemble the corrugated pipe 21.
[0036] Furthermore, a fixing bolt 262 is provided on the slot 261 and passes through the slot 261 and the block 26, so that the slot 261 and the block 26 are threadedly fixed, which increases the stability of the connection between the slot 261 and the block 26.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
