[0024] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship during the normal use of the product.

[0026] The terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature. In the drawings of the embodiments of the present utility model, a coordinate system XYZ is set, where the positive direction of the X-axis represents the left side, the negative direction of the X-axis represents the right side, the positive direction of the Y-axis represents the front side, the negative direction of the Y-axis represents the rear side, the positive direction of the Z-axis represents the upper side, and the negative direction of the Z-axis represents the lower side.

[0027] An embodiment of the present utility model provides a seeding device, in combination with Figures 1-6As shown in the figure, it includes a housing 1, on which a seeding drum 3, a grooving drum 4 and a transmission assembly 5 are provided. The grooving drum 4 is arranged in front of the seeding drum 3. The transmission assembly 5 includes a first transmission wheel 51, a second transmission wheel 52, a third transmission wheel 53, a fourth transmission wheel 54, a fifth transmission wheel 55, a sixth transmission wheel 56, a first transmission belt, a second transmission belt and a third transmission belt. The first transmission wheel 51 and the second transmission wheel 52 are connected by the first transmission belt in transmission. The second transmission wheel 52 and the third transmission wheel 53 are connected by the second transmission belt in transmission. The third transmission wheel 53 and the fourth transmission wheel 54 are meshed. The fourth transmission wheel 54 and the fifth transmission wheel 55 are connected by the third transmission belt in transmission. The fifth transmission wheel 55 and the sixth transmission wheel 56 are meshed. One end of the seeding drum 3 is connected to the second transmission wheel 52, and one end of the grooving drum 4 is connected to the sixth transmission wheel 56;

[0028] The first transmission wheel 51 is driven by a motor 6 to rotate forward, and the first transmission wheel 51 drives the second transmission wheel 52 to rotate forward, so that the seeding drum 3 rotates forward. The second transmission wheel 52 drives the third transmission wheel 53 to rotate forward, the third transmission wheel 53 drives the fourth transmission wheel 54 to rotate backward, the fourth transmission wheel 54 drives the fifth transmission wheel 55 to rotate backward, and the fifth transmission wheel 55 drives the sixth transmission wheel 56 to rotate forward, so that the grooving drum 4 rotates forward.

[0029] As Figure 1 shown, the forward direction is the clockwise direction or the counterclockwise direction, and the reverse direction is the direction opposite to the forward direction. The rotation speed of the seeding drum 3 can be controlled by adjusting the rotation speed of the motor 6. The grooving drum 4 can adjust the installation height through an adjusting screw 44 to adapt to seedling trays of different heights.

[0030] Connecting the motor 6 and the first transmission wheel 51 can avoid the phenomenon that connecting the motor 6 to the second transmission wheel 52 causes too much space occupation in the left and right directions of the seeding device. By setting belt transmission connection and gear meshing connection, the transmission direction can be adjusted, so that the seeding drum 3 and the grooving drum 4 can rotate in the same direction, and at the same time, it does not affect the up and down movement of the grooving drum 4.

[0031] In the seeding device of the present utility model, by setting the first transmission wheel 51, the second transmission wheel 52, the third transmission wheel 53, the fourth transmission wheel 54, the fifth transmission wheel 55 and the sixth transmission wheel 56 to cooperate, it is possible to drive the seeding drum 3 and the grooving drum 4 to rotate in the same direction simultaneously with one motor 6. In this way, not only the structure is simple and stable, but also the rotation speed ratio between the seeding drum 3 and the grooving drum 4 is fixed, and there is no need for separate debugging.

[0032] The housing 1 is provided with an arc-shaped opening 11. The grooving roller 4 includes a rotating shaft portion 41. The rotating shaft portion 41 passes through the arc-shaped opening 11 and is slidably connected to the arc-shaped opening 11. The sixth transmission wheel 56 is connected to one end of the rotating shaft portion 41.

[0033] As Figure 2 shown, in this embodiment, there are two arc-shaped openings 11, which are respectively arranged on the left and right sides of the housing 1. The rotating shaft portion 41 is in a rod-shaped structure, and both ends of the rotating shaft portion 41 are slidably connected to the two arc-shaped openings 11 respectively. When the grooving roller 4 rotates, it will move up and down due to the thickness of the seedling tray. The arrangement of the arc-shaped opening 11 can make the structure of the grooving roller 4 more stable during rotation.

[0034] A shaft sleeve 42 is connected to the rotating shaft portion 41. A limiting ring 421 protrudes from the edge of the shaft sleeve 42. The limiting ring 421 is in abutting connection with the outer side wall of the arc-shaped opening 11. The limiting ring 421 is used to limit the rotating shaft portion 41 in the left-right direction.

[0035] As Figure 5 and 6 shown, in this embodiment, there are two shaft sleeves 42, which are respectively connected to the left and right sides of the rotating shaft portion 41, used to limit the rotating shaft portion 41 from both left and right ends, stabilize the structure, and prevent the rotating shaft portion 41 from shaking out of the arc-shaped opening 11 during rotation.

[0036] The arc-shaped opening 11 includes a long arc portion 111 and a short arc portion 112. The arc length of the long arc portion 111 is greater than that of the short arc portion 112. The short arc portion 112 is located in front of the long arc portion 111.

[0037] As Figure 6 shown, such an arrangement is more conducive to the rotation of the grooving roller 4.

[0038] The seeding device further includes a hopper 2 that penetrates up and down. The hopper 2 is arranged above the seeding roller 3. A number of through seeding openings 31 are provided on the seeding roller 3. The hopper 2 is communicated with the seeding openings 31 so that seeds can flow into the seeding openings 31 through the hopper 2.

[0039] As Figure 3 and 4 shown, in this embodiment, the seeding openings 31 are evenly distributed on the outer surface of the seeding roller 3. The opening above the hopper 2 is larger than the opening below. Seeds are poured from above the hopper 2 and flow into the seeding roller 3 from the opening below the hopper 2 under the action of gravity. When the seedling tray passes below the seeding roller 3, the seeds flow out from the seeding openings 31 and evenly fall into the grooves, realizing precise seeding.

[0040] The seeding device further includes a brush 7, which is disposed above the seeding drum 3 and is in abutting connection with the seeding drum 3.

[0041] As Figure 3 shown, in this embodiment, the brush 7 is used to brush off the seeds adhered to the surface of the seeding drum 3. The position of the brush 7 can be adjusted and fixed by bolts to control the size of the gap between the brush 7 and the seeding drum 3, thereby realizing fine adjustment of the seeding amount.

[0042] A plurality of convex ribs 43 are spaced apart on the grooving drum 4. When the grooving drum 4 rolls, the convex ribs 43 roll on the seedling tray to generate grooves for seeding.

[0043] As Figure 5 shown, in this embodiment, there are 14 grooves on the grooving drum 4.

[0044] The seeding device further includes a baffle 8, which is located in front of the seeding drum 3. The baffle 8 is used to block and guide the seeding direction of the seeds in the seeding drum 3.

[0045] As Figure 3 shown, when the seeding drum 3 rotates, the seeds are easily thrown out from the seeding port 31. Setting the baffle 8 can block the seeds from flying forward. In this embodiment, the baffle 8 is arc-shaped and the arc is adapted to the arc of the seeding drum 3. While blocking the seeds from flying forward, the baffle 8 guides the seeds to fall downward into the seedling tray.

[0046] A plurality of screw holes 12 are provided at the bottoms of the left and right ends of the housing 1 to facilitate the disassembly of the seeding device from the production line.

[0047] As Figure 2 shown, the screw holes 12 can be waist-shaped holes to adapt to different production lines and increase the adaptability. So that the seeding device can be installed on different production lines with the same left-right dimension.

[0048] Another embodiment of the present invention provides a seeding production line, including the seeding device as described above.

[0049] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
