Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The rice seedling tray sowing mechanism of this utility model embodiment will be described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, the rice seedling tray sowing mechanism of this utility model embodiment may include a frame 10, a primary feeding component 20 and a secondary conveying component 30.

[0026] The frame 10 is provided with a first shell 101 and a second shell 102. The second shell 102 is located below the first shell 101. The first shell 101 has a first inlet 1011 and a first outlet 1012 on its upper and lower sides, respectively. The second shell 102 has a second inlet 1021 and a second outlet 1022 on its upper and lower sides, respectively. The first outlet 1012 is connected to the second inlet 1021.

[0027] The primary feeding assembly 20 is disposed inside the first housing 101 and may include a movable component 201 and a metering component 202. The metering component 202 is disposed inside the first outlet 1012 and may include a fixed upper plate 2021 and a movable lower plate 2022. The upper plate 2021 has a plurality of material holes 20211. One end of the lower plate 2022 is attached to the bottom surface of the upper plate 2021. The lower plate 2022 described in this embodiment can block the bottom of the material holes 20211. The movable component 201 is movably disposed inside the first housing 101 and its two ends are respectively disposed on both sides of the material holes 20211. The two ends of the movable component 201 are respectively attached to the upper plate 2021 and the lower plate 2022. The movable component 201 may include a movable part 2011, a first end 2012, and a second end 2013. The movable part 2011 is coaxially arranged with the first housing 101, and a first driving component 61 is connected to the movable part 2011. The first end 2012 and the second end 2013 are respectively connected to the movable part 2011 and are respectively in contact with the upper plate 2021 and the lower plate 2022. The other end of the lower plate 2022 extends into the first housing 101, and a spring 50 is provided between the other end of the lower plate 2022 and the first outlet 1012. A baffle 2014 is provided on one side of the movable component 201. The free end of the baffle 2014 abuts against the inner wall of the first housing 101 and is located near the first inlet 1011. It is understood that the baffle 2014 can promote the accumulation of seeds entering the first housing 101 on the upper plate 2021.

[0028] By repeatedly rotating the movable component 201 described in this embodiment, seeds are continuously and quantitatively fed into multiple feed holes 20211, thereby achieving precise sowing. Furthermore, the movable component 201 effectively avoids the problem of seed blockage during the conveying process, ensuring smooth conveying.

[0029] The secondary conveying assembly 30 is located inside the second housing 102 and may include a conveying wheel 301 and a plurality of hoppers 302 circumferentially disposed on the outer surface of the conveying wheel 301. The conveying wheel 301 is coaxially disposed with the second housing 102 and is disposed inside the second housing 102 via a second driving member. The hoppers 302 are provided with a plurality of partitions 40, which divide the hoppers 302 into a plurality of conveying chambers 3021. Each conveying chamber 3021 is located below a corresponding material hole 20211, and the seeds in each material hole 20211 can fall precisely into the corresponding conveying chamber 3021.

[0030] The secondary conveying assembly 30 can systematically deliver a fixed quantity of seeds one by one to the lower tray 70, ensuring that the seeds are evenly arranged on the tray 70. It is worth mentioning that the multiple hoppers 302 can also temporarily store a fixed quantity of seeds, further improving the flexibility and efficiency of the sowing operation.

[0031] It should be noted that the first housing 101 and the second housing 102 described in this embodiment are both circular in cross-section, and the first driving member 61 described in this embodiment has the function of controlling the forward and reverse rotation of the moving member 201, and the second driving member described in this embodiment has the function of controlling the forward and reverse rotation of the conveying wheel 301. Both can be motors.

[0032] In one possible scenario, in the prefabricated tray seeding method, the tray 70 is located on the conveyor belt of the assembly line operation. This application is positioned above the conveyor belt, so that the mechanism can accurately seed the tray 70 as it passes through the mechanism.

[0033] Specifically, when actually carrying out the seed sowing operation on the feed tray 70, the relevant personnel need to first put the seeds into the first housing 101 through the first inlet 1011. At this time, the seeds will accumulate on the upper tray 2021, and some of the seeds will completely fill the multiple feed holes 20211 on the upper tray 2021. Then, the first drive unit 61 is activated, and the moving part 201 is operated to start rotating. The first end 2012 of the moving part 201 will push aside the seeds accumulated on the upper tray 2021.

[0034] Next, the second end 2013 of the moving part 201 will contact the feeding tray 70 and push the lower tray 2022 to rotate. During this process, the spring 50 will be stretched, and the seeds that were originally filled in the feeding hole 20211 will lose support due to the rotation of the lower tray 2022, and thus fall out of the feeding hole 20211 and enter the corresponding hopper 302 through the second inlet 1021.

[0035] After entering the hopper 302, the seeds are evenly distributed in multiple conveying chambers 3021. At this time, the second drive unit is activated, controlling the conveyor wheel 301 to rotate, so that the multiple hoppers 302 can move precisely and sequentially below the second inlet 1021 to receive the seeds falling from the feed hole 20211. As the conveyor wheel 301 continues to rotate, the seeds will fall from the second outlet 1022 and land precisely on the feed tray 70 passing below, completing one sowing process.

[0036] When it is necessary to feed the next hopper 302 into the second inlet 1021, the relevant personnel again control the moving part 201 to rotate in the reverse direction via the first drive component 61. During the reverse rotation, the second end 2013 of the moving part 201 separates from the lower plate 2022. The lower plate 2022 rotates in the reverse direction under the action of the spring 50, re-sealing the feed hole 20211 to prevent seeds from falling further. At the same time, as the first end 2012 moves in the reverse direction, the seeds in the first housing 101 fall back to the upper plate 2021, filling the space that was cleared. By repeating the above steps, continuous and precise seeding of the feed tray 70 can be achieved.

[0037] In summary, the rice seedling tray sowing mechanism of this utility model embodiment can continuously and stably output a quantitative amount of seeds, ensuring the accuracy of seed placement. At the same time, it effectively avoids the problem of seed blockage during the transportation process and ensures smooth transportation.
