[0021] In order to explain the idea and purpose of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 8 As shown, a seedling shooting structure for accelerating the shooting of seedlings comprises a seedling shooting tube 10 and an acceleration structure 20, wherein the top of the seedling shooting tube 10 is a seedling introduction entrance 11, and the bottom is a seedling drop-out exit 12, and the acceleration structure 20 is arranged at the seedling drop-out exit 12, and the acceleration structure 20 comprises a power source 21, a first seedling shooting acceleration roller 22, a second seedling shooting acceleration roller 23, a first gear 24 and a second gear 25; an acceleration channel is formed between the first seedling shooting acceleration roller 22 and the second seedling shooting acceleration roller 23, the first gear 24 and the second gear 25 are meshed with each other, the rotating shaft of the first seedling shooting acceleration roller 22 is connected to the first gear 24, and the rotating shaft of the second seedling shooting acceleration roller 23 is connected to the second gear 25, and the power source 21 is used to drive the first seedling shooting acceleration roller 22 or the second seedling shooting acceleration roller 23 to rotate.

[0023] like Figures 1 to 8 As shown, the rice seedling shooting tube 10 is a trumpet-shaped structure, the rice seedling putting inlet 11 of the rice seedling shooting tube 10 is large, and the rice seedling dropping out outlet 12 of the rice seedling shooting tube 10 is small. When the rice seedlings enter the rice seedling shooting tube 10 from the rice seedling putting inlet 11, the rice seedlings fall out from the rice seedling dropping out outlet 12 under the action of their own gravity, and the rice seedlings fall into the acceleration channel. The power source 21 drives the first rice seedling shooting acceleration roller 22 and the second rice seedling shooting acceleration roller 23 to rotate. The rotation of the first rice seedling shooting acceleration roller 22 and the second rice seedling shooting acceleration roller 23 drives the rice seedlings to be shot out faster, thereby increasing the shooting speed of the rice seedlings and making it easier for the rice seedlings to contact with the soil in the field.

[0024] like Figures 1 to 8 As shown, the surface of the first seedling-shooting acceleration roller 22 is provided with a first acceleration ridge 221 for increasing friction, and the surface of the second seedling-shooting acceleration roller 23 is provided with a second acceleration ridge 231 for increasing friction. The first acceleration ridge 221 is parallel to the first seedling-shooting acceleration roller 22, and the second acceleration ridge 231 is parallel to the second seedling-shooting acceleration roller 23. The first acceleration ridge 221 and the second acceleration ridge 231 can increase the shooting speed of the seedlings.

[0025] like Figures 1 to 8 As shown, there are multiple seedling shooting tubes 10, and the multiple seedling shooting tubes 10 are connected in a straight line. The number of the first seedling shooting acceleration rollers 22 and the second seedling shooting acceleration rollers 23 are equal to the number of the seedling shooting tubes 10, and the multiple first seedling shooting acceleration rollers 22 rotate synchronously, and the multiple second seedling shooting acceleration rollers 23 rotate synchronously.

[0026] like Figures 1 to 8As shown, multiple first seedling shooting acceleration rollers 22 are connected by the same rotating shaft, and multiple second seedling shooting acceleration rollers 23 are connected by the same rotating shaft. The power source 21 drives the multiple first seedling shooting acceleration rollers 22 and the multiple second seedling shooting acceleration rollers 23 to rotate simultaneously. Seedlings enter each seedling shooting tube 10, and the first seedling shooting acceleration rollers 22 and the second seedling shooting acceleration rollers 23 respectively accelerate the seedlings in the corresponding seedling shooting tube 10 to shoot out.

[0027] like Figures 1 to 8 As shown, the first seedling-shooting acceleration roller 22 is penetrated with a plurality of first through holes 222 along the axial direction, and the second seedling-shooting acceleration roller 23 is penetrated with a plurality of second through holes 232 along the axial direction. The first seedling-shooting acceleration roller 22 and the second seedling-shooting acceleration roller 23 are made of flexible materials and have a certain elasticity. The first through holes 222 increase the elasticity of the first seedling-shooting acceleration roller 22, and the second through holes 232 increase the elasticity of the second seedling-shooting acceleration roller 23, so as to prevent the first seedling-shooting acceleration roller 22 and the second seedling-shooting acceleration roller 23 from pinching the seedlings.

[0028] like Figures 1 to 8 As shown, an extension tube 30 is provided below the acceleration structure 20, the extension tube 30 and the seedling-shooting tube 10 are fixed to each other, and the acceleration structure 20 is arranged between the extension tube 30 and the seedling-shooting tube 10. The extension tube 30 can play a role of wind shielding.

[0029] like Figures 1 to 8 As shown, the power source 21 is a motor. The motor drives the rotating shaft of the first seedling-shooting acceleration roller 22 to rotate, the rotation of the first seedling-shooting acceleration roller 22 drives the first gear 24 to rotate, the first gear 24 drives the second gear 25 to rotate, and the second gear 25 drives the second seedling-shooting acceleration roller 23.

[0030] The above is a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications are also considered to be within the protection scope of the present utility model.
