[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 As shown, a seedling transplanter can be widely used in the planting of paddy field crops such as rice. The frame 1 is equipped with a synchronously operating seedling delivery device 2, a seedling pulling device 3 and a seedling throwing device 5. The seedling pulling device 3 pulls out the seedlings A delivered by the seedling delivery device 2 and throws them into the seedling guide cylinder 4. The seedlings fall from the seedling guide cylinder 4 into the seedling throwing device 5, and the seedlings A are accelerated and thrown into the paddy field. The seedling guide cylinder 4 is fixed on the frame 1. The seedling delivery device 2 and the seedling pulling device 3 adopt the electric seedling delivery and mechanical seedling pulling mechanisms disclosed in the utility model of the seedling clamping and delivering mechanism of the seedling transplanter with application number CN202422555146.4 filed by the applicant on October 22, 2024, which will not be described in detail here. It should be understood that the seedling delivery device 2 and the seedling pulling device 3 are not limited to this. The seedling throwing device 5 can also be combined with the mechanical seedling delivery device and mechanical seedling pulling device commonly used in this field. The contribution of the present invention to the existing technology is mainly reflected in the seedling throwing device 5, which is not easy to crush the nutrient soil ball wrapping the seedling roots, and the potted seedlings are not easily broken up. The planting effect is good and the planting efficiency is high. It can be widely used in the planting operations of paddy field crops such as rice.
[0025] The following focuses on the rice seedling throwing device 5.
[0026] like Figures 2 to 4As shown in the drawings, the seedling throwing device 5 comprises a driving seedling throwing wheel 51 and a driven seedling throwing wheel 52. The driving seedling throwing wheel 51 comprises a seedling throwing wheel body 511 which is drivingly connected to a driving shaft 514. The driving shaft 514 is driven by a power device (not shown in the drawings). The power device is preferably an electric motor. The electric motor is convenient to control and is not affected by other factors (such as the rotating speed of an engine, the walking speed of a pot seedling transplanting machine, etc.), thereby ensuring the seedling throwing effect under any working condition. Two rims are arranged on the two sides of the seedling throwing wheel body 511. An annular groove is formed between the two rims. The rim on the left side of the driving seedling throwing wheel 51 is formed by a left gear 513. The rim on the right side of the driving seedling throwing wheel 51 is formed by a right gear 512.
[0027] Similarly, the driven seedling throwing wheel 52 comprises a seedling throwing wheel body 521 which is rotatably installed on a supporting shaft 524. Two rims are arranged on the two sides of the seedling throwing wheel body 521. An annular groove is formed between the two rims. The rim on the left side of the driven seedling throwing wheel 52 is formed by a left gear 523. The rim on the right side of the driven seedling throwing wheel 52 is formed by a right gear 522. The annular groove of the driving seedling throwing wheel 51 and the annular groove of the driven seedling throwing wheel 52 are oppositely arranged in the radial direction to form a seedling throwing channel. The left gear 513 of the driving seedling throwing wheel 51 is engaged with the left gear 523 of the driven seedling throwing wheel 52 and has the same number of teeth and the same diameter. The right gear 512 of the driving seedling throwing wheel 51 is engaged with the right gear 522 of the driven seedling throwing wheel 52 and has the same number of teeth and the same diameter. The gears arranged on the rims can make full use of the structure of the rims to form the seedling throwing channel. During seedling throwing, the driving seedling throwing wheel 51 and the driven seedling throwing wheel 52 can rotate at the same speed in opposite directions, thereby improving the seedling throwing effect. From the perspective of realizing driving connection, the driving seedling throwing wheel 51 and the driven seedling throwing wheel 52 can be drivingly connected only by the gears arranged on the rims on one side or by friction wheels instead of the foregoing gear structure to realize the rotation at the same speed in opposite directions. Of course, other driving devices can be used to drivingly connect the driving seedling throwing wheel 51 and the driven seedling throwing wheel 52. However, in this case, the structure will become complex.
[0028] In the present example, in order to facilitate manufacturing, the right gear 512, the left gear 513 and the seedling throwing wheel body 511 of the driving seedling throwing wheel 51 are separately arranged and fixedly connected together. The right gear 522, the left gear 523 and the seedling throwing wheel body 521 of the driven seedling throwing wheel 52 are separately arranged and fixedly connected together. That is, the rims and the seedling throwing wheel bodies are preferably separately arranged.
[0029] A flexible material is arranged on the circumferential surface of the seedling throwing wheel body 511 or the seedling throwing wheel body 521. The flexible material does not exceed the annular groove. The flexible material is preferably a flexible brush 515 or 525 (see Figure 3 and Figure 4 ).
[0030] AsFigure 4 As shown, when the pot seedlings A fall into the seedling throwing channel between the driving seedling throwing wheel 51 and the driven seedling throwing wheel 52 from the seedling guiding cylinder 4, the flexible material can well adapt to the shape of the pot seedlings by deformation, the driving seedling throwing wheel and the driven seedling throwing wheel rotate at the same speed and in opposite directions, which not only can accelerate the seedling throwing, but also is not easy to squeeze the nutrient soil mass wrapped around the seedling roots, the pot seedlings are not easy to be scattered, thereby improving the planting effect and efficiency of rice.
[0031] The utility model is not limited to the above-mentioned embodiment, all kinds of improvements based on the conception, principle, structure and method of the utility model will fall into the protection scope of the utility model.
