[0026] In order to make the purpose, technical scheme and advantage of the utility model more clear, the utility model will be described in further detail below in conjunction with the drawings. Only this declaration, the up, down, left, right, front, back, inside, outside and other orientation words appearing or about to appear in the text of the utility model, only with the drawings of the utility model as the base, it is not the specific limitation to the utility model.

[0027] As Figures 1-2The tobacco seedling floating culture seeding and soil covering device shown in the figure comprises a crossbeam 1, a rack connecting piece 2, a belt rotating shaft 3, a substrate conveying belt 4 and a substrate hopper 10, characterized in that the upper part of the rack connecting piece 2 is provided with two symmetrical crossbeams 1, the inside of the crossbeam 1 is provided with the belt rotating shaft 3 and the substrate conveying belt 4, the belt rotating shaft 3 is connected with the second sprocket 8 on the speed regulating motor 7 through the belt rotating shaft sprocket 6 and the first transmission chain to form the first group of transmission structure; the upper part of the crossbeam 1 is provided with the substrate hopper 10, and the inside of the substrate hopper 10 is provided with a substrate stirring frame 12, the substrate stirring frame 12 is connected with the fourth sprocket on the speed regulating motor 7 through the second transmission chain to form the second group of transmission structure; one end of the crossbeam 1 is provided with a material scraping mechanism 13; the substrate stirring frame 12 is arranged on the rotating shaft in the cavity of the substrate hopper 10, and one end of the rotating shaft is provided with a third sprocket, the third sprocket is connected with the fourth sprocket through the second transmission chain; the outside of the speed regulating motor 7 and the second sprocket 8 is provided with a sprocket protection cover 9; one end of the rack connecting piece 2 is provided with a tray rack connecting fixing piece 11, and the tray rack connecting fixing piece 11 is connected with the seeder; the substrate blocking plate 5 is arranged on the two side crossbeams 1 of the substrate conveying belt 4.

[0028] It should be noted that during the tobacco seedling seeding process, the floating tray needs to be covered with soil, and the traditional method generally adopts manual soil covering or simple tray scraping facilities on the seeder to simply cover the seeds with substrate, which has large labor intensity, and the covering is not uniform by using the tray scraping covering method, resulting in poor overall efficiency. Therefore, we design an equipment which can be connected with the seeder and can automatically guide the material to cover the soil, so as to uniformly cover the soil on the seeds.

[0029] It should be further explained that in order to realize automatic film covering operation, the substrate conveying belt 4 is arranged in the middle of the two crossbeams 1, which realizes automatic material guiding under the driving of the speed regulating motor 7, and continuously guides the soil to the planting hole tray under the traction of the seeder, and in order to realize automatic feeding, the substrate hopper 10 is arranged on the upper part of the crossbeam 1, which can store soil in the substrate hopper 10, and automatically discharge the soil by its own gravity, and guide the material by means of the substrate conveying belt 4.

[0030] It should be further explained that in order to prevent the soil in the substrate hopper 10 from being blocked during discharging, a substrate stirring frame 12 is also designed, which is connected with the fourth sprocket on the speed regulating motor 7 through the second transmission chain to form the second group of transmission structure, and realizes stirring during material guiding, thereby improving the practicability of the equipment.

[0031] As Figures 1-8As shown, the scraping mechanism 13 includes a fixed support 1301, a receiving plate 1304, a scraping plate 1302, a guide plate 1303 and a damping mechanism 14, the fixed support 1301 is arranged on the rack connecting piece 2, and the inside of the fixed support 1301 is provided with the damping mechanism 14 and the receiving plate 1304, the receiving plate 1304 is provided with the scraping plate 1302 and the guide plate 1303; the damping mechanism 14 is symmetrically arranged on the inner wall of the fixed support 1301, and the upper part of the damping mechanism 14 is fixedly provided with the receiving plate 1304.

[0032] It should be noted that after long-term trial, it is found that part of the clay will stick to the surface of the conveying belt 4 during the transportation of the clay, and if the clay is not removed, the weight of the conveying belt will become larger and larger, based on this, the scraping mechanism 13 is designed to fall the clay on the surface of the conveying belt.

[0033] It should be further noted that the fixed support 1301 is arranged at one end of the rack connecting piece 2, and two damping mechanisms 14 are arranged in the inside of the rack connecting piece 2, the receiving plate 1304 is arranged on the damping mechanism 14, and the upper part of the receiving plate 1304 is provided with the scraping plate 1302 and the guide plate 1303, wherein the scraping plate 1302 is arranged close to the surface of the conveying belt for scraping the clay, and the guide plate 1303 can guide the clay to avoid falling on the damping mechanism 14.

[0034] As shown in Figures 1-7 As shown, the damping mechanism 14 includes a connecting support 1401, a first sliding rod 1402, a receiving support 1405, a sliding table 1406, a second sliding rod 1407 and a second pressure spring 1409, the receiving support 1405 is movably connected with the first sliding rod 1402 on the connecting support 1401 through connecting holes 1408 on the two sides, and the first sliding rod 1402 is provided with a first pressure spring 1403 on the outer wall to form a first elastic structure; the sliding table 1406 is movably connected with the second sliding rod 1407 in the inside of the receiving support 1405 through a sliding block at the bottom, and the second sliding rod 1407 is provided with a second pressure spring 1409 on the outer wall to form a second elastic structure; the scraping plate 1302 is connected with the receiving plate 1304 through a fixing screw.

[0035] It needs to be explained that through the test, it is found that the scraping plate 1302 is in direct contact with the surface of the conveying belt, at this time the scraping effect is best, but the muddy soil often contains small stones or uneven places, which will appear after contacting with the scraping plate 1302. The contradiction phenomenon will cause the whole scraping mechanism to be tilted, which is easy to cause the damage of the components. Based on this, we designed two groups of damping mechanisms 14, wherein the whole receiving support 1405 is arranged between the first sliding rod 1402 and the connecting support 1401, and the first pressure spring 1403 is arranged on the outer wall of the first sliding rod 1402 to form the first group of elastic structures, so that the whole structure has the elastic stress up and down. The sliding table 1406 is arranged on the second sliding rod 1407 inside the receiving support 1405, and the second pressure spring 1409 is arranged on the second sliding rod 1407. After the sliding table 1406 is in contact with one end of the second pressure spring 1409, it has a left and right elastic stress, so that the whole equipment has a left and right elastic force. Under this structure, when the scraping plate 1302 contacts the protruding part, it can have a certain buffering capacity, avoiding the damage of the components caused by hard contact.

[0036] It needs to be further explained that the first pressure spring 1403 is located between the connecting hole 1408 and the connecting point of the connecting support 1401, and the second pressure spring 1409 is also designed in the same way. The purpose is to obtain the elastic stress.

[0037] The above describes the embodiments of the utility model in detail in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the person skilled in the art without departing from the purpose of the utility model.
