[0002] A seedling raising and sowing machine is a mechanical device used for seedling raising and sowing operations in farmland or greenhouses. It mixes seeds, fertilizers and water and accurately configures them into the soil to ensure the growth and development of crops. The seedling raising and sowing machine can improve the uniformity, yield and quality of crops, reduce labor intensity and save time costs. Patent No. CN210537702U discloses a seedling tray conveying device for a self-propelled rice seedling raising and sowing machine, including a frame, two side limiting rods, a conveying brush assembly, a sliding plate, a seedling tray guiding assembly, a transmission chain. The sliding plate is fixedly connected to the periphery of the bottom of the frame, and the seedling tray guiding assembly is fixedly connected above the left and right side frames of the frame... This patent conveys the seedling tray by setting a seedling tray conveying brush, but the brush is a vertical structure. During the conveying process, the brush is easily directly inserted into the seedling tray, and the soil or seedlings are pulled out and taken away, thus affecting the use. Therefore, we introduce a conveying device of a seedling raising and sowing machine. Content of the Utility Model

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A conveying device of a seedling raising and sowing machine, including a frame 1, an arc portion 4 is arranged at the front end of the frame 1, a conveying mechanism 2 is fixedly connected to both the front part and the rear part of the upper end of the frame 1, and a separating device 3 is fixedly connected to the middle part of the upper end of the frame 1.

[0025] In this embodiment, the separating device 3 includes a cross frame 31. The cross frame 31 is of a "U" - shaped structure. A vertically penetrating sliding groove 33 is formed at the upper end of the cross frame 31. A number of sliding blocks 32 are slidably connected in the sliding groove 33. At the front ends of the number of sliding blocks 32, round seats 325 are fixedly connected. At the front ends of the number of round seats 325, limit bolts 324 are threadedly connected. In the number of sliding blocks 32, notch openings 321 are formed. At the rear ends of the number of sliding blocks 32, grooves 322 are fixedly connected. At the lower ends of the number of sliding blocks 32, limit partition plates 323 are fixedly connected. The number of limit partition plates 323 are all of a "T" - shaped structure. The number of grooves 322 and the number of notch openings 321 are both slidably connected with the sliding blocks 32. The number of limit bolts 324 and the number of round seats 325 are both located at the front part of the cross frame 31. There is no contact between the number of limit partition plates 323 and the frame 1. The cross frame 31 is fixedly connected to the upper end of the frame 1. There is no contact between the limit partition plates 323 and the disc 26, avoiding the disc 26 rotating and causing bumps to the limit partition plates 323.

[0026] In this embodiment, the conveying mechanism 2 includes a first mounting frame 21. A second mounting frame 24 is arranged at the right end of the first mounting frame 21. The first mounting frame 21 and the second mounting frame 24 are arranged in parallel. The first mounting frame 21 and the second mounting frame 24 are jointly movably connected with a driving roller 25 through bearings. A number of discs 26 are fixedly connected to the outer surface of the driving roller 25. A number of brush hairs 22 are fixedly connected to the outer surfaces of the number of discs 26. Bend portions 23 are arranged on the number of brush hairs 22. The second mounting frame 24 and the first mounting frame 21 are both fixedly connected to the frame 1. When the driving roller 25 rotates, a sprocket needs to be installed on the driving roller 25, and then the power is transmitted through a chain to drive the driving roller 25 to rotate. By arranging the bend portions 23 on the number of brush hairs 22, the ends of the number of brush hairs 22 are in an arc - shaped bending shape, so that when the number of brush hairs 22 contact the seedling tray, it can be avoided that the number of brush hairs 22 directly insert into the seedling tray, and further avoid the number of brush hairs 22 picking out the soil and seedlings in the seedling tray, reducing the burden of subsequent manual rework.

[0027] It should be noted that the present utility model is a conveying device of a seedling - raising and sowing machine. During use, first, the positions of the number of sliding blocks 32 on the separating device 3 are adjusted according to the size of the seedling tray, and then the limit bolts 324 are rotated to squeeze and limit the moved sliding blocks 32, thereby limiting the positions of the limit partition plates 323. Under the action of the number of limit partition plates 323, it is convenient to guide the seedling tray, improving the neatness of the seedling tray falling. After installing the sprocket and the power chain on the driving roller 25, the driving roller 25 is driven to rotate under the action of the power chain. The number of discs 26 on the driving roller 25 rotate, and the brush hairs 22 on the discs 26 drive the seedling tray to move. Since the bend portions 23 are arranged on the number of brush hairs 22, it can be avoided that the brush hairs 22 directly insert into the seedling tray to pick out the soil and seedlings, avoiding increasing the manual burden.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
