Description
Technical Field
[0001] This utility model relates to the field of automatic seeders, and in particular to an automatic seeder for precise positioning of seed tray seedlings. Background Technology
[0002] Plug seedling cultivation is a modern seedling technology that involves sowing seeds in plastic trays (plug trays) with multiple small holes (holes) and cultivating uniform and robust seedlings under artificially controlled environmental conditions. With the acceleration of global population growth and urbanization, food security issues have become prominent, making it crucial to improve agricultural production efficiency.
[0003] The existing automatic seeding machine for plug tray seedlings consists of a conveyor, a soil covering machine, and a seeder. The conveyor is driven by a motor to transport empty plug trays to the corresponding positions for sowing and subsequent processes in an orderly manner, ensuring smooth connection between each link. The soil covering machine uses rollers and a hopper to spray soil from the hopper onto the plug trays, providing a suitable growth environment for the seeds. The seeder uses an air suction device to quantitatively pick up seeds from the seed storage bin and then put them into each hole of the plug tray.
[0004] Many existing automatic seeders suffer from inaccurate positioning when transporting seed trays of different sizes. This requires frequent manual adjustments and interventions by operators, increasing labor intensity and costs. Moreover, this inaccurate positioning method limits the applicability of the seeder to diverse seed trays and fails to meet the diverse seedling needs of modern agriculture. Therefore, an automatic seeder with precise positioning for seed tray seedling cultivation is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 and Figure 4 An embodiment of this utility model provides: a precision positioning automatic seeder for seedling tray cultivation, including a frame 1. The frame 1 is used to bear the overall weight of the seeder and various forces generated during operation, ensuring the stability of the overall structure of the seeder. Connecting plates 2 are fixedly connected to both sides of the top of the frame 1. The connecting plates 2 play the role of transmitting force and fixing the position of the device. A positioning mechanism 3 is provided inside the connecting plates 2. A collecting mechanism 4 is provided inside the frame 1. A sowing mechanism 5 is provided outside the frame 1 and the connecting plates 2.
[0035] The positioning mechanism 3 includes two sliding frames 301, which are used to position and adjust the acupoint. The two sliding frames 301 are slidably connected to the interior of two connecting plates 2. Support columns 303 are slidably connected to the interior of the two sliding frames 301 on adjacent sides. The support columns 303 are used for sliding and restraint. A compression spring 302 is slidably connected between the sliding frames 301 and the support columns 303. The compression spring 302 provides elastic support force to ensure the stability and reliability of positioning. Rotary shafts 304 are fixedly connected to the exterior of the two sliding frames 301 on adjacent sides. The rotating shafts 304 are used to adapt to different sizes and shapes. The acupuncture plate has two rotating shafts 304 with adjacent sides internally connected to abutments 305, which directly contact the acupuncture plate. The opposite sides of the two abutments 305 are respectively supported on the outside of adjacent sides of two support columns 303. An adjustment assembly for adjustment is snapped onto the outside of the sliding frame 301. The adjustment assembly includes two clamps 306, which are used to fix the position of the sliding frame 301. The inside of the two clamps 306 is respectively snapped onto the outside of the two sliding frames 301. An adjustment knob 307 is threadedly connected inside the two clamps 306. The adjustment knob 307 adjusts the clamping force of the clamps 306 through the threaded connection.
[0036] Reference Figure 2 , Figure 3 and Figure 5 The collecting mechanism 4 includes two drive motors 401, which are externally fixedly connected to the outside of the frame 1. The drive motors 401 are used to generate power. The motor housings are made of aluminum alloy to ensure good heat dissipation and mechanical strength. Two transmission tracks 402 are slidably connected inside the frame 1. The transmission tracks 402 rotate under the drive of the drive motors 401 to transport the pits and impurities. The output ends of the two drive motors 401 are respectively fixedly connected to the rotating shafts of the two transmission tracks 402. On the outside of the two conveyor tracks 402, multiple transport scrapers 403 are fixedly connected. The transport scrapers 403 are used to scrape up and transport excess soil that falls on the bottom of the frame 1 and the conveyor tracks 402. Inside the frame 1, brushes 404 are fixedly connected to the adjacent side of the two conveyor tracks 402. The brushes 404 are used to clean the residual soil and impurities on the surface of the conveyor tracks 402. A collection box 405 is slidably connected to the bottom inner wall of the frame 1. The collection box 405 is used to collect excess soil and impurities for easy cleaning and recycling.
[0037] Two transport frames 406 are fixedly connected to the top two sides of the connecting plate 2. The transport frames 406 provide installation positions to realize the transport and adjustment of soil. Placement frames 407 are fixedly connected to the top of the two transport frames 406 respectively. Placement frames 407 are used to store soil and provide soil source for sowing. The bottom of the two placement frames 407 are threadedly connected to the outer side of the two placement frames 407 respectively. The quantity plates 408 are used to adjust the amount of soil falling and realize precise control of soil. The outer side of the two transport frames 406 is threadedly connected to the central scraper 409. The central scraper 409 is used to adjust the distribution of soil and can scrape off excess soil and concentrate it in the middle of the conveyor belt 402.
[0038] Reference Figure 1 and Figure 6 The sowing mechanism 5 includes an air pump 501 and a roller press 502. The air pump 501 is externally fixedly connected to the inside of the frame 1. The air pump 501 provides power to the hole press 503 and the seeder 504 by compressing air. The bottom of the roller press 502 is fixedly connected to the top of the connecting plate 2. The roller press 502 compacts the soil in the seed tray. The hole press 503 is fixedly connected to the top of the connecting plate 2. The hole press 503 presses out sowing holes in the substrate of the seed tray to provide a suitable position for seed sowing. The seeder 504 is fixedly connected to the top of the connecting plate 2. Under the air pressure of the air pump 501, the seeder 504 accurately sows the seeds into the sowing holes of the seed tray to achieve precision sowing.
[0039] Working principle: The specific operation is as follows: Loosen the adjustment knob 307 so that the clamp 306 no longer clamps the sliding frame 301. At this time, the sliding frame 301 can slide in the connecting plate 2. When the sliding frame 301 moves, it drives the support column 303 and the abutment column 305 to move. When in use, the abutment column 305 is tightly pressed against the side of the seed tray under the elastic force of the compression spring 302 during transportation, so as to achieve the initial positioning of the seed tray. After adjusting the position, tighten the adjustment knob 307 so that the clamp 306 clamps the sliding frame 301 and fixes its position. When the seed tray is transported to the bottom of the seeder 504, the compression spring 302 squeezes the support column 303 and presses the abutment column 305 to squeeze the seed tray in the middle, thus completing the precise positioning of the seed tray.
[0040] Start the drive motor 401, which drives the rotating shaft of the transmission track 402 to rotate, causing the transmission track 402 to rotate. The transport scraper 403, which is fixed to the outside of the transmission track 402, moves together with the transmission track 402 to scrape up and transport excess soil and impurities. When the transmission track 402 rotates, the brush 404 contacts the surface of the transmission track 402 to brush off the remaining soil and impurities, which fall into the collection box 405 located on the inner wall of the bottom of the frame 1. The collection box 405 is connected to the frame 1 by a sliding connection, which makes it easy to remove, clean and recycle excess seeds.
[0041] When in use, the drive motor 401 is started. Driven by the drive motor 401, the transmission belt 402 transports the seed tray to the bottom of the transport frame 406. Soil falls from the placement frame 407 onto the transport frame 406. The amount of soil transported is limited by the metering plate 408. When the seed tray covered with soil is scraped off by the centralized scraper 409, the press roller 502 compacts the soil into the seed tray. The air pump 501 is started so that the hole presser 503 presses the soil in the seed tray out of the sowing hole. Then, the positioning mechanism 3 accurately positions the soil, so that the seeder 504, under the air pressure of the air pump 501, accurately sows the seeds into the sowing hole of the seed tray, achieving precision sowing.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
