Technical Field

[0001] This utility model relates to the field of seedling raising equipment technology, and in particular to a seedling raising, screening and sowing device. Background Technology

[0002] Hybrid rice seedling trays, also known as plug trays, are an important tool for hybrid rice cultivation, ensuring rapid and large-scale production. The materials used to make seedling trays generally include polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene. The manufacturing methods include blow molding and injection molding. Generally, hybrid rice seedling plug trays are made of polystyrene.

[0003] Currently, Chinese Patent Publication No. CN202603273U discloses a rice seedling tray made of organic materials. It includes a seedling tray body, which comprises an upper tray layer and a lower tray layer formed by pressing organic materials. A fertilizer layer is provided between the upper tray layer and the lower tray layer. The upper tray layer, the lower tray layer, and the fertilizer layer are integrally formed by hot pressing.

[0004] Although this type of rice seedling tray can be used for rice seedling cultivation, it requires staff to place the rice seeds into the corresponding grooves by hand. Since there are many grooves in the seedling tray, it is difficult to accurately control the number of seeds placed in each groove, and the workload is large, which puts a heavy burden on the planting staff. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a seedling raising, screening and sowing device to solve the problem in the prior art that it is difficult to quickly sow rice seeds into each groove of the seedling raising tray in the required quantity.

[0006] To achieve the above and other related objectives, this utility model provides a seedling raising, screening, and sowing device, including a seedling tray. A sieve plate movably connected to the seedling tray and capable of being installed on the upper side of the seedling tray is provided. The sieve plate has sieve holes communicating with the seedling tray for seed passage. A baffle plate movably connected to the sieve plate, capable of controlling the opening and closing of each sieve hole, is provided at the outlet end of the sieve hole. The baffle plate has through holes corresponding to the sieve holes.

[0007] By adopting the above technical solution, the sieve plate can be installed on the seedling tray, and the seeds can be poured onto the sieve plate. By shaking the seedling tray, the seeds on the sieve plate can be shaken into the sieve holes. Then, by moving the baffle, the seeds in the sieve holes can be directed into the seedling tray, thus achieving rapid seed sieving. The operation is simple and convenient, and it can be used in various seedling trays. Moreover, the structure is simple, easy to transport, and suitable for remote mountainous terrain.

[0008] In one embodiment of this utility model, a plurality of seedling trays are evenly arranged inside the seedling tray, and the sieve holes on the sieve plate correspond one-to-one with the seedling trays.

[0009] By adopting the above technical solution, seeds can be separated into their corresponding seedling trays after falling through the sieve holes, thus achieving rapid seed separation.

[0010] In one embodiment of the present invention, the baffle is slidably connected to the lower side of the sieve plate along the horizontal plane. The sieve plate is also provided with a limiting block that abuts against and can position the sieve hole and the through hole. The limiting block moves one end of the baffle in the direction of movement.

[0011] By adopting the above technical solution, the opening and closing of the screen holes on the screen plate can be realized by pulling the baffle, which is convenient to operate. Moreover, the position of the baffle can be accurately positioned by the limiting block, so that the screen holes can be aligned with the through holes.

[0012] In one embodiment of the present invention, the sieve plate is provided with an upwardly extending enclosure around its perimeter, and the edges of the enclosure are provided with outwardly protruding edges.

[0013] By adopting the above technical solution, when the sieve plate is shaken, the surrounding barrier can prevent the seeds from sliding off the sieve plate. Furthermore, by setting a raised edge on the outside of the barrier, it is easier for workers to hold the sieve plate by the raised edge, which facilitates its operation and transportation.

[0014] In one embodiment of this utility model, the sieve hole shape is set to rectangular, the opening area of ​​the through hole is larger than the sieve hole area, and the sliding direction of the baffle is set along the width direction of the sieve hole.

[0015] By adopting the above technical solution, the seeds are usually elongated, which allows the seeds to enter the sieve holes according to the required position, and also allows the baffle to slide a shorter distance, making the overall structure more compact and space utilization more efficient.

[0016] In one embodiment of the present invention, a material trough that communicates with the surface of the sieve plate and extends downward is also provided on one side of the enclosure, and the material trough is configured as an R-shaped trough.

[0017] By adopting the above technical solution, excess seeds on the surface of the sieve plate can be poured into the trough, and the R-shaped groove setting allows for a larger seed storage capacity, and the seeds can be poured out of the trough for the next use.

[0018] In one embodiment of the present invention, a magnet for magnetically connecting a baffle is also embedded in the sieve plate, and a metal part magnetically connected to the magnet is correspondingly provided in the baffle.

[0019] By adopting the above technical solution, the baffle can be limited by magnetic attraction, which can ensure that the position of the baffle will not shift when the seedling tray is shaken, thus ensuring its screening effect.

[0020] As described above, the seedling raising, sieving, and sowing device of this utility model has the following beneficial effects: it can install the sieve plate on the seedling tray and pour the seeds onto the sieve plate. By shaking the seedling tray, the seeds on the sieve plate are shaken into the sieve holes. Then, by moving the baffle, the seeds in the sieve holes are directed into the seedling tray, thus achieving rapid seed sieving. It is simple and convenient to operate, applicable to various seedling trays, and has a simple structure, is easy to transport, and is suitable for remote mountainous terrain.
