[0001] The utility model relates to the field of plug seeding device, especially plug seeding device. BACKGROUND

[0002] The plug seeding device is a planting machine for sowing seeds in holes with certain row distance and hole distance, which is mainly used in the seedling raising process of crops such as vegetables, flowers, melons and fruits, and can accurately sow seeds into the plug tray filled with substrate to achieve the sowing effect of one hole one seed or one hole multiple seeds. The plug seeding device not only improves the sowing efficiency, but also ensures the accuracy of sowing and the quality of seedlings, and is an important tool in modern seedling raising technology.

[0003] The existing plug seeding device usually needs manual driving equipment to take seeds and sow them in the plug tray during use. The manual operation needs to continuously repeat the actions of taking seeds and sowing, which is difficult to meet the demand of large-scale production, resulting in low overall production efficiency and low overall sowing efficiency.

[0004] Therefore, in view of the above-mentioned existing plug seeding device, manual driving equipment is usually needed to take seeds and sow them in the plug tray, and the manual operation needs to continuously repeat the actions of taking seeds and sowing, which is difficult to meet the demand of large-scale production, resulting in low overall production efficiency and low overall sowing efficiency. Therefore, the plug seeding device can be designed to realize automatic sowing, reduce manual operation, avoid seed missing or over-sowing, and greatly improve the sowing efficiency. SUMMARY

[0005] In order to overcome the problem that the existing plug seeding device usually needs manual driving equipment to take seeds and sow them in the plug tray, and the manual operation needs to continuously repeat the actions of taking seeds and sowing, which is difficult to meet the demand of large-scale production, resulting in low overall production efficiency and low overall sowing efficiency.

[0007] Preferably, by employing multiple sets of drop heads to simultaneously transport individual seeds, combined with water flow to guide the seeds from the drop holes into the seed trays, automatic sowing is achieved, reducing manual operation and significantly improving sowing efficiency. Furthermore, since each drop head passes through a single seed at a time, the seeds are evenly sown in the seed trays, preventing missed or over-sown seeds. Secondly, different drop heads can be replaced to adapt to different seed tray planting needs, increasing the device's versatility. A transmission pipe transports water to the limiting frame, sequentially guiding the seeds through the drop holes and ensuring each seed falls accurately into the seed tray, guaranteeing automated sowing. A rotary motor connected to a conveyor belt drives the seed trays for efficient sowing. Depending on different sowing needs, limiting blocks connect and replace the seed trays, enabling diversified sowing to adapt to different crops and planting environments, which is beneficial for crop growth and yield improvement.

[0008] Preferably, the transmission pipe is located on the outer wall of the limiting frame and is connected to the limiting frame. One end of the transmission pipe is equipped with a water storage tank, and a water pump is installed between the water storage tank and the transmission pipe. Water is transmitted to the inside of the limiting frame through the transmission pipe, which in turn drives the seeds through the dropping holes and guides each seed to fall into the seed tray through the dropping head, ensuring that the seeds fall accurately into the seed holes and guaranteeing the automated sowing of the equipment.

[0009] Preferably, the roller is located inside the running platform, and a conveyor belt is fitted on the outer wall of the roller.

[0013] Preferably, the outer side of the operating platform is equipped with a material ejector, and the inside of the material ejector has a sliding groove. By using the material ejector to eject and remove the substrate after sowing and covering the seed trays, the design of the material ejector allows the seed trays to be automatically ejected and removed after sowing and covering the substrate, making the sowing process more continuous, reducing the interruption caused by removing the trays, and adapting to the needs of large-scale production.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared to traditional tray seeders, this device utilizes multiple sets of drop heads to simultaneously transport individual seeds. Combined with water flow, the seeds fall from the drop holes into the trays, achieving automatic sowing, reducing manual operation, and significantly improving sowing efficiency. Furthermore, the drop heads ensure even sowing of individual seeds in the trays, preventing missed or over-sown seeds. Secondly, different drop heads can be replaced to adapt to different seed types, increasing the device's versatility.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4 This utility model provides an embodiment of a seed tray seeder, which includes a running platform 1, a seeding component, and an auxiliary component. The upper end of the running platform 1 is equipped with a seeding component for automatic seeding, and one end of the running platform 1 is equipped with an auxiliary component for assisting the seeding and feeding of the seed tray. The seeding component includes a limiting frame 201, a partition 204, a transmission pipe 205, a water storage tank 207, a roller 208, a conveyor belt 209, a fixing plate 210, and a seed tray 212. The limiting frame 201 is located at the upper end of the running platform 1. The upper end of the limiting frame 201 is provided with a cover plate 202. A feeding frame 203 is provided on one side of the upper end of the cover plate 202. The lower end of the limiting frame 201 is provided with multiple sets of feeding heads. A feeding hole is opened between the feeding head and the limiting frame 201. Multiple sets of partitions 204 are provided inside the limiting frame 201.

[0024] Please see Figures 1-2In this embodiment, the transmission pipe 205 is located on the outer wall of the limiting frame 201 and is connected to the limiting frame 201. One end of the transmission pipe 205 is provided with a water storage tank 207, and a water pump 206 is provided between the water storage tank 207 and the transmission pipe 205. Water is transmitted to the inside of the limiting frame 201 through the transmission pipe 205, which sequentially drives the seeds through the dropping holes and guides each seed to fall into the seed tray 212 through the dropping head, ensuring that the seeds fall accurately into the seed holes and ensuring the automated sowing of the equipment. The roller 208 is located inside the running platform 1, and a conveyor belt 209 is sleeved on the outer wall of the roller 208. One end of the roller 208 is located on the outer wall of the running platform 1 and is provided with a rotary motor 211. The surface of the conveyor belt 209 is provided with multiple sets of fixing plates 210. By using the rotary motor 211 to connect the conveyor belt 209 to drive the seed tray 212 to transmit seeds, the sowing speed is significantly improved, the dependence on manual labor is reduced, and the high-efficiency sowing of the equipment is achieved.

[0025] Please see Figures 1-3 In this embodiment, a seedling tray 212 is provided above the fixing plate 210, and a limiting block is provided at the lower end of the seedling tray 212. The seedling tray 212 is fixedly connected to the fixing plate 210 through the limiting block. By replacing the seedling tray 212 with the limiting block according to different sowing needs, diversified sowing can be achieved, adapting to different crops and planting environments, which is beneficial to crop growth and yield improvement. The auxiliary components include a support frame 301, an auxiliary rod 302, a lead screw 303, a scraper 304, a drive module 305, a conveying pipe 306, a storage box 307, and a material return rack 308. 1. Located on one side of the limiting frame 201, the inner wall of the limiting frame 201 is provided with a lead screw 303. One end of the lead screw 303 is located on the outer wall of the support frame 301 and is provided with a drive module 305. The inner wall of the support frame 301 away from the lead screw 303 is provided with an auxiliary rod 302. The auxiliary rod 302 and the outer wall of the lead screw 303 are provided with scrapers 304. By using the lead screw 303 to connect the scrapers 304, the covered substrate is scraped flat, which facilitates the subsequent treatment of the seed trays 212, reduces manual operation time, ensures uniform substrate coverage, provides a good growth environment for seeds, and improves the uniformity of seedling emergence.

[0026] Please see Figures 2-4In this embodiment, the outer wall of the support frame 301 is provided with a conveying pipe 306, and the inner wall of the support frame 301 is provided with a discharge groove. The end of the conveying pipe 306 away from the support frame 301 is provided with a storage box 307. An air pump is provided between the conveying pipe 306 and the storage box 307. By using the air pump, the substrate is transferred to the surface of the seed tray 212 after sowing through the conveying pipe 306, reducing the tedious process of manual soil covering and leveling. The complex process is concentrated on a production line, which significantly improves the sowing efficiency. The outer side of the running platform 1 is provided with a material return frame 308. The inside of the material return frame 308 is provided with a sliding groove. By using the material return frame 308 to return and remove the substrate after sowing and covering the seed tray 212, the design of the material return frame 308 enables the seed tray 212 to be automatically returned and removed after sowing and covering the substrate, making the sowing process more continuous, reducing the interruption caused by removing the tray, and adapting to the needs of large-scale production.

[0027] During operation, firstly, according to different sowing needs, the seed tray 212 is replaced using a limiting block connection. The replaced seed tray 212 with the limiting block is inserted into the fixing plate 210 for positioning. Some seeds are added from inside the feeding rack 203. Water is pumped to the limiting rack 201 via a transmission pipe 205 using a water pump 206, sequentially driving the seeds through the discharge holes. Simultaneously, a rotary motor 211 connected to a roller 208 drives a conveyor belt 209 to move the seed tray 212. The rotation speed of the roller 208 is adjusted and controlled according to the spacing of the seeds guided out by the water flow. When the seed tray 212... When the seeds are conveyed to the bottom center of the limiting frame 201, the water flow guides each seed through the drop hole to fall into the seed tray 212 through the drop head, ensuring that the seeds fall accurately into the seed holes, realizing automatic sowing, reducing manual operation, greatly improving sowing efficiency, and avoiding missed or over-sown seeds. Secondly, different drop heads can be replaced according to different sowing needs to adapt to the planting of different seed trays 212. After a single seed falls into a single seed tray 212, the remaining seeds inside the limiting frame 201 are automatically flowed into the drop hole by the water flow, and then slowly fall into the second set of conveyed seed trays 212, realizing the automated and efficient sowing of the equipment.

[0028] When the seedling tray 212 moves to the support frame 301 via the conveyor belt 209, the substrate is preferentially transferred to the surface of the seedling tray 212 after sowing through the conveying pipe 306 using an air pump. The drive module 305 is activated in conjunction with the scraper 304 connected by the lead screw 303 to scrape the covered substrate back and forth, which facilitates the subsequent processing of the seedling tray 212, reduces manual operation time, ensures uniform substrate coverage, and provides a good growth environment for the seeds. When the seedling tray 212 is conveyed to the top of the unloading rack 308, the unloading rack 308 lifts the seedling tray 212 and it is inserted into the limiting block by the slide groove. The limiting block slides along the inside of the slide groove to unload the seedling tray 212, making the sowing process more continuous, reducing the interruption caused by tray removal, and adapting to the needs of large-scale production.

[0029] Through the above steps, by using multiple sets of drop heads to simultaneously transport individual seeds, combined with water flow to drive the seeds from the drop holes into the seed tray 212, automatic sowing is achieved, reducing manual operation and significantly improving sowing efficiency. Furthermore, since each drop head passes through a single seed, the seeds are evenly sown in the seed tray 212, avoiding missed or over-sown seeds. Secondly, different drop heads can be replaced according to different sowing needs, adapting to different seed trays 212 for planting different seeds, increasing the device's applicability. Water is transmitted through the transmission pipe 205 to the limiting frame 201, sequentially driving the seeds through the drop holes and guiding each seed through the drop head into the seed tray 212, ensuring accurate seed placement and automated sowing. A rotary motor 211 connected to the conveyor belt 209 drives the seed tray 212 for efficient sowing. According to different sowing needs, the seed tray 212 can be replaced using limiting blocks, achieving diversified sowing, adapting to different crops and planting environments, and benefiting crop growth and yield improvement.
