Specific implementation method:

[0018] The present invention is further described below with reference to specific embodiments. Figure 1 —3:

[0019] A seedling sowing machine with an auxiliary spreading assembly includes a frame 1, and a conveying mechanism 2 arranged on the frame 1 and used to convey a seedling tray 3, a seed container 4 and a sowing assembly 5 whose feeding end is connected to the discharging end of the seed container 4 are arranged on the frame 1 above the conveying mechanism 2 from top to bottom, and an auxiliary spreading assembly located above the conveying mechanism 2 is arranged on the frame 1 located in front of or behind the sowing assembly 5, the feeding end of the auxiliary spreading assembly is connected to the lower end of a guide inclined slide 6, the upper end of the guide inclined slide 6 is connected to the inner cavity of the seed container 4, and a valve assembly for opening or blocking the guide inclined slide 6 is arranged on the guide inclined slide 6. Among them, the sowing assembly 5 can adopt an existing common structure, and in this embodiment, the sowing assembly 5 and the conveying mechanism 2 both adopt the public structure of the existing Chinese utility model patent (authorization announcement number CN219459735U), so it will not be described in this embodiment. When it is necessary to carry out scattering operations, the valve assembly is opened, and the seedling seeds can enter the auxiliary spreading assembly from the seed container 4 through the material guide inclined slide 6 for scattering. At the same time, if the scattering density required is relatively large, the sowing assembly 5 can carry out sowing operations together with the auxiliary spreading assembly; when hole sowing and row sowing operations are required, the valve assembly is closed to block the seedling seeds from entering the auxiliary spreading assembly.

[0020] The utility model adds an auxiliary scattering component to the existing seeding seeder, and shares the seed container 4 with the sowing component 5, effectively controlling the equipment cost, and only needs to fill the seed container 4 with seedling seeds. The operation is simple and convenient, and the operating states of the sowing component 5, the auxiliary scattering component and the valve component can be controlled according to actual sowing needs. Therefore, on the basis of the existing technology satisfying the sowing needs of row sowing and hole sowing, the auxiliary scattering component is used to meet the sowing needs of scattering, effectively improving the sowing applicability of the equipment.

[0021] Furthermore, the auxiliary spreading component can adopt the negative pressure adsorption structure of the sowing roller which is the same as the existing sowing component 5. In the present embodiment, in order to reduce the cost and structure of the equipment, the auxiliary spreading component includes an auxiliary bracket 7 fixed on the frame 1, and the auxiliary bracket 7 is rotatably connected with an auxiliary roller 8 which is arranged horizontally and perpendicularly to the conveying direction of the conveying mechanism 2. The outer wall surface of the auxiliary roller 8 is circumferentially evenly distributed with a plurality of arc-shaped grooves 9 opened along its axial direction. The auxiliary bracket 7 is provided with an auxiliary hopper 10 whose discharge port is located above the auxiliary roller 8, and the lower end of the material guiding inclined slide 6 is connected with the auxiliary hopper 10. The auxiliary bracket 7 is provided with an arc-shaped tile plate 11 around the outer periphery of the auxiliary roller 8, and the upper end of the arc-shaped tile plate 11 is located below the discharge port of the auxiliary hopper 10 facing the positive rotation side of the auxiliary roller 8, and the lower end of the arc-shaped tile plate 11 is located below the auxiliary roller 8, and a conveying space for accommodating a single seed for seedling cultivation is formed radially between the arc-shaped tile plate 11 and the arc-shaped groove 9. That is, the seedling seeds enter the auxiliary hopper 10 through the material guiding inclined slide 6, and driven by the positively rotating auxiliary roller 8, a single seedling seed enters the conveying space formed by the arc-shaped tile plate 11 and the arc-shaped groove 9 in the radial direction, and falls into the seedling tray 3 on the conveying mechanism 2 at the lower end of the arc-shaped tile plate 11 to achieve spreading.

[0022] In order to avoid multiple seedling seeds being accumulated in the same conveying space in the radial direction at the same time, causing the seedling seeds to be damaged under the shear force of the arc-shaped tile 11 and the arc-shaped groove 9, a brush body 12 is arranged between the auxiliary hopper 10 and the upper end of the arc-shaped tile 11, that is, the accumulated multiple seedling seeds are blocked by means of the brush body 12 to screen out excess seedling seeds; and, in order to be able to adjust the radial position of the brush body 12 to adjust the screening position according to the actual size of the seedling seeds, the brush body 12 can move inward and outward relative to the auxiliary roller 8 along the radial direction of the auxiliary roller 8.

[0023] Furthermore, the specific structure of the radial displacement adjustment of the brush body 12 is as follows: a limiting slide rail is arranged on the outer wall surface of the auxiliary hopper 10 along the radial direction of the auxiliary roller 8, and a brush support seat 13 is slidably fitted in the limiting slide rail, the brush body 12 is arranged at the bottom of the brush support seat 13, and the top of the brush support seat 13 is screwed on the adjusting screw 14, and the adjusting screw 14 is connected to the auxiliary hopper 10 by rotating along the radial direction of the auxiliary roller 8.

[0024] In order to reduce equipment costs, a bending limit plate 15 is provided on the outer wall surface of the auxiliary hopper 10, and a through groove structure with a notch radially inwardly arranged toward the auxiliary roller 8 is formed between the bending limit plate 15 and the auxiliary hopper 10, and the through groove structure is the limiting slide rail.

[0025] In this embodiment, the rolling driving structure of the auxiliary roller 8 is as follows: one end of the auxiliary roller 8 is transmission-connected to a servo motor 17 fixed on the auxiliary bracket 7 via a gearbox 16 .

[0026] In addition, the valve assembly can adopt the existing common flip-type valve structure. In the present embodiment, in order to reduce the cost of the equipment, the valve assembly includes a cut-off slot opened between the material guide inclined slide 6 and the seed container 4, and a valve plate body 18 whose inner end slides and is inserted into the cut-off slot. The outer end of the valve plate body 18 is located outside the cut-off slot and is provided with a control handle 19.

[0027] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
