The seed protection shaft 3-3 is sleeved on the seed protection shaft 3-1, the middle shaft 3-4 and the two pressure belt shafts 3-6, the seed protection shaft 3-1, the middle shaft 3-4 and the two pressure belt shafts 3-6 are enveloped in the seed protection shaft 3-3, and the center lines of the seed protection shaft 3-1, the middle shaft 3-4 and the two pressure belt shafts 3-6 are parallel to each other and are vertically arranged on the surfaces of the side plates 3-7. The seed protection component 3 is arranged on the inner side of the support 1-3 through a connecting piece, the seed protection gear 3-8 and the roller gear 2-2 form gear transmission after installation, the outer part of the seed protection belt 3-3 between the two pressure belt shafts 3-6 is in wrapping contact with the outer wall surface of the roller 2-6, and therefore the seed protection belt 3-3 is provided with rotary driving force by the seed protection shaft 3-1. In this embodiment, the wrapping section formed by wrapping the protective tape 3-3 on the roller 2-6 is determined by two wrapping tape shafts 3-6, wherein the lower wrapping tape shaft 3-6 is located below the roller 2-6, and the upper wrapping tape shaft 3-6 is located above the roller 2-6, so that as shown in fig. 3, the initial position of the wrapping section is located at the downstream position after the roller 2-6 passes the highest point during the rotation, and the end position of the wrapping section is located at the upstream position before the roller 2-6 passes the lowest point during the rotation. The distances between the specific starting position and the specific ending position and the highest point and the lowest point of the rollers 2 to 6 can be optimized and adjusted according to the actual conditions so as to smoothly carry and drop seeds.
In addition, referring to fig. 6, in this embodiment, two shaft arms uniformly distributed along the axis may be further provided on the two pinch shafts 3-6, and all the shaft arms of the pinch shafts 3-6 have the same diameter.

In addition, the brush assembly 4 is used for removing the excess seeds in the seed filling process, because the seed filling process of the invention is realized by the seeds in the seed box 2-8 entering the cells 2-9 under the action of gravity, the excess seeds exceeding the capacity of the cells 2-9 can exist, and the excess seeds can protrude out of the cells 2-9, namely out of the outer wall surface of the roller 2-6. Therefore, the brush component 4 can be arranged at the periphery of the roller 2-6, and the contact position of the brush component 4 and the outer wall surface of the roller 2-6 is arranged between the seed filling position where the seed outlet is positioned on the roller 2-6 and the initial position where the roller 2-6 is wrapped by the seed protecting belt 3-3, so that in the rotating process of the roller 2-6, the brush action of the brush component 4 on the roller 2-6 can be utilized, and the redundant seeds protruding out of the cells 2-9 can be brushed into the seed box 2-8 again. It should be noted that the brushing of the rollers 2-6 by the brush assembly 4 should be limited to brushing only the seeds protruding from the outer walls of the rollers 2-6, and not the seeds in the pockets 2-9. And the seed box 2-8 is provided with a return port matched with the brush component 4, so that the brushed seeds can enter the seed box 2-8 again. Therefore, as long as the shapes and the sizes of all the cells 2-9 on the rollers 2-6 are controlled to be consistent, the quantity of the seeds carried by each cell 2-9 can be basically consistent.
The specific implementation form of the brush assembly 4 may be various, and in the present embodiment, as shown in fig. 7, it includes a brush shaft 4-1, a brush gear 4-2, a brush sleeve 4-3, a brush body 4-4, an intermediate gear 4-5, and a tripod 4-6.

As shown in figure 8, one end of the brush shaft 4-1 is fixed on the bracket 1-3, the other end of the brush shaft 4-1 is fixed with one corner of the tripod 4-6, and the other two corners of the tripod 4-6 are respectively fixed with the side plate 3-7 outside the protection component 3 and the end part of the roller shaft 2-1 through the support. The brush body 4-4 which is contacted with the outer wall surface of the roller 2-6 is arranged outside the brush sleeve 4-3, and the brushing range of the brush body 4-4 can cover each row of cells 2-9. The brush gear 4-2 is fixed at one end of the brush sleeve 4-3 close to the inner side of the support 1-3, and the brush sleeve 4-3 is arranged on the brush shaft 4-1 through a bearing. The intermediate gear 4-5 is arranged on the inner side of the support 1-3 through a shaft and a bearing, the intermediate gear 4-5 is meshed with the roller gear 2-2 to form gear transmission, the intermediate gear 4-5 is also meshed with the brush gear 4-2 to form gear transmission, the brush gear 4-2 is meshed with the roller gear 2-2 through the intermediate gear 4-5 to form gear transmission, and the brush sleeve 4-3 is driven to drive the brush body 4-4 to clean the outer wall surface of the roller 2-6. In this embodiment, the brush hairs of the brush body 4-4 are just tangent to the outer wall surface of the roller 2-6, a differential speed can be formed between the brush hairs and the roller 2-6 in the process of rotating along with the brush sleeve 4-3, and the rotating direction of the brush body 4-4 faces to the direction of the seed box 2-8, so that redundant seeds protruding out of the surface of the roller 2-6 can be cleaned into the seed box 2-8.
In addition, the vibrator 5 is used for applying high-frequency vibration to the seed metering assembly 2, so that the seed filling and dropping of the seeds are promoted, and the seeds are prevented from being stuck and cannot fall freely.

S4, seed cleaning and seed falling: when the cells 2-9 on the roller 2-6 rotate to a seed dropping position close to the lowest position of the roller 2-6, the seed-protecting belts 3-3 are rotated to be separated from the surface of the roller 2-6, so that the cells 2-9 on the roller 2-6 are exposed, seeds fall into a seedling tray in a row under the action of gravity, meanwhile, when the cells 2-9 of the roller 2-6 rotate to the lowest position, the seed-removing sheets slide through two seed-removing slits 2-10 at the bottom of the cells 2-9, the seeds which do not fall out of the cells 2-9 under the action of gravity are ejected by the seed-removing sheets and fall into the seedling tray, and meanwhile, the vibrator 5 continuously works to promote the seeds to smoothly fall into the seedling tray.
The roller 2-6 continuously rotates to execute the steps S1-S4, and the cells 2-9 on each circumference of the roller 2-6 continuously complete the procedures of seed filling, seed brushing, seed carrying, seed cleaning and seed falling, thereby realizing the continuous strip seeding of the seeds.
