Description

Technical Field

[0001] This utility model relates to the field of rice planting technology, specifically to a seedling cultivation device for rice planting. Background Technology

[0002] Rice is susceptible to various pathogenic microorganisms during its growth, including bacteria, fungi, and viruses. These pathogens can affect seed germination and seedling growth, and even cause the spread of diseases throughout the field. Therefore, sterilizing rice seeds is an important agricultural management measure in rice cultivation. The main purpose is to reduce the occurrence of diseases, improve seed germination rate, and ensure healthy seedling growth. Uneven distribution of rice seeds during seedling raising leads to uneven seedling growth, with some seedlings being too dense while others are sparse, increasing the difficulty of seedling management and reducing seedling quality. In addition, uneven seed distribution can also affect the seedlings' resistance to adverse conditions, increase the risk of pests and diseases, reduce seedling raising efficiency, and lead to inconsistent seedling growth after transplanting, ultimately affecting the yield and quality of rice. Therefore, ensuring uniform seed distribution is crucial for improving seedling quality and subsequent management.

[0003] Utility model patent CN221449277U discloses a seedling cultivation device for rice planting, comprising a frame with a seedling tray fixedly installed inside. Multiple through-type seedling troughs are evenly arranged on the top plate of the seedling tray. Electric cylinders are symmetrically installed on the left and right side plates of the seedling tray, with their extended ends pointing vertically downwards and fixedly connected to a mounting plate via connectors. The mounting plate is located directly below the seedling tray. A stop bar is inserted into the mounting plate below each seedling trough, with the upper part of the stop bar slidably inserted into the seedling trough. This device has a simple structure, reasonable design, and strong practicality, effectively improving worker efficiency and reducing labor intensity. The permeable holes on the stop bars allow excess water to drain from the seedling troughs, preventing damage to the seedlings due to over-irrigation.

[0029] like Figures 1 to 11 As shown, the stirring unit 2 includes a stirring cam 201, a stirring return spring 202, a stirring sliding plug 203, a stirring conveyor belt 204, a stirring rotating shaft 205, a stirring inlet housing 206, a stirring inlet pipe 207, a stirring housing 208, a stirring valve 209, and a moving cylinder 210. The stirring cam 201 is slidably engaged with the screening cam 109. The stirring sliding plug 203 is fixedly mounted on the stirring cam 201 and slidably disposed within the stirring inlet housing 206. A stirring return spring is disposed between the stirring cam 201 and the stirring inlet housing 206. 202. A stirring inlet pipe 207 is provided on the stirring inlet housing 206. The other end of the stirring inlet pipe 207 is provided on the stirring housing 208. A stirring rotating shaft 205 is rotatably provided inside the stirring housing 208.

The support 3 is fixedly mounted on the output shaft of the moving cylinder 210. The moving cylinder 210 is fixedly mounted on the base 4.

[0030] like Figures 1 to 11As shown, this utility model discloses a seedling cultivation device for rice planting. Its working principle is as follows: Rice seeds are fed into the mixing shell 208 through the feed inlet. Disinfectant for the rice seeds is added from the top of the mixing liquid inlet shell 206. At this time, the channel between the mixing liquid inlet shell 206 and the mixing liquid inlet pipe 207 is blocked by the mixing sliding plug 203. The screening motor 110 is turned on, and its rotation drives the screening crank ring 107, screening crank ring 106, screening shaft 108, and screening cam 109 to rotate. During this process, the rotation of screening crank ring 106 and screening crank ring 107 drives the screening disc 104, screening cylinder 102, screening baffle 101, and screening spring 103 to reciprocate on the support 3 via the screening connecting rod 105. The sliding mechanism prepares the rice seeds for sieving. Simultaneously, the sieving cam 109 rotates, pushing the stirring cam 201 and the stirring sliding plug 203 to slide. The sliding stirring sliding plug 203 causes the channel between the sieving crank ring 106 and the stirring liquid inlet pipe 207 to open or close intermittently. At this time, the disinfectant for rice seeds in the stirring liquid inlet shell 206 is intermittently added to the rice seeds in the stirring shell 208. The rotating sieving shaft 108 drives the stirring rotating shaft 205 to rotate through the stirring conveyor belt 204. When the stirring rotating shaft 205 rotates, it stirs the rice seeds in the stirring shell 208. Combined with the intermittent inflow of disinfectant from the stirring liquid inlet shell 206, the rice seeds and disinfectant are fully mixed, preventing uneven mixing from causing diseases and pests in rice seedlings.

[0031] After the rice seeds and disinfectant are fully mixed inside the mixing shell 208, the mixing valve 209 is manually opened, allowing the rice seeds to fall onto the sieving plate 104. The reciprocating sliding of the sieving plate 104 ensures that the rice seeds on the sieving plate 104 fall evenly into the sieving holes. Once the seeds are evenly distributed into the sieving holes, the sieving cylinder 102 is activated, pushing the sieving baffle 101 to slide, causing the sieving baffle 101 to be misaligned with the sieving holes. At this point, the rice seeds on the sieving holes of the sieving plate 104 fall onto the cultivation tray 5 for subsequent seedling cultivation. This process is to ensure that the rice seeds fall evenly onto the cultivation tray 5, preventing seed overlap and affecting the quality of seedling cultivation.

[0032] The movable cylinder 210 pushes the support 3, the sieving section 1, and the stirring section 2 to move above the culture tray 5, sowing seeds evenly in the culture tray 5. After sowing seeds in multiple culture trays 5, the operator carries out seedling cultivation. After seedling cultivation is completed, the support plate 6 is pulled out, the culture tray 5 is removed, and the entire seedling cultivation operation is completed.
