DETAILED DESCRIPTION

[0035] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1-Figure 9 As shown, in this example, a seed pressing roller device for seeding seed trays includes a frame 3, a seed pressing roller 4, a driven wheel 5, a seed storage box, and a seeding bin 16, and the seed storage box and the seeding bin 16 form a seeding assembly 6. Figure 1 , Figure 2 As shown, the head and tail ends of the frame 3 are rotatably connected to the seed pressing roller 4 and the driven wheel 1 5 respectively, and the frame 3 between the driven wheel 1 5 and the seed pressing roller 4 is rotatably connected to the driven wheel 2 19, and the driven wheel 2 19 is connected to the seed pressing roller 4 through a transmission mechanism 1 for synchronous rotation. Of course, the driven wheel 2 can also be connected to the driven cold wheel 1 for synchronous rotation.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8As shown, in this example, the seed storage box includes a main body 29 and a bottom plate 30. The main body 29 is a rectangular box-shaped body, which is fixed on the frame 3. Two bottom plates 30 are relatively installed at the bottom cavity of the main body 29. The two bottom plates 30 are tilted relative to each other, and the gap between the bottom ends of the two bottom plates 30 forms a discharge port. The front, back and top sides of each bottom plate 30 are connected to the cavity wall of the main body 29 through flexible parts. The flexible parts are strips cut from common cloth. The sides of the bottom plates 30 are connected to the corresponding cavity walls of the main body through cloth strips to ensure sealing and activity space. A rotating shaft 31 is pivotally connected to the main body adjacent to the bottom plate, and a plurality of eccentric wheels 32 are fixed on the rotating shaft at intervals along the axial direction, such as an elliptical shape.

[0039] The two rotating shafts 31 are respectively connected to the driven wheel 2 19 through the transmission mechanism 2 to rotate synchronously. The eccentric wheel 32 abuts against the bottom plate during the rotation of the rotating shaft 31. The eccentric wheel, the rotating shaft, the bottom plate, etc. form a vibration assembly.

[0040] For the transmission mechanism 1 and the transmission mechanism 2, such as common synchronous belts, chain belts, pulleys, etc., for example, the transmission mechanism 1: a pulley 13 or a sprocket is concentrically fixed at the end of the seed pressing roller, one end of the synchronous belt is sleeved on the pulley and the other end is sleeved on the driven wheel 2. Of course, the pulley can also be concentrically fixed on the driven wheel 2, and connected to the pulley on the seed pressing roller through the synchronous belt. The transmission mechanism 2 is consistent with the transmission mechanism 1, such as one end of the synchronous belt is sleeved on the pulley at the end of the rotating shaft and the other end is sleeved on the driven wheel 2.

[0041] During the movement of the frame, the seed pressing roller rotates, which synchronously causes the driven wheel 2 and the rotating shaft to rotate. During the rotation of the rotating shaft, the eccentric wheel abuts against the bottom plate at different positions, causing the bottom plate to be in a vibrating state, so that the seeds can flow out smoothly from the discharge port.

[0042] In this example, the seeding bin 16 is located below the seed storage box and the top inlet of the seeding bin 16 is connected to the discharge port. Figure 7 , Fig. 9 As shown, the seeding wheel 20 is pivotally connected in the seeding bin 16, and the bottom of the seeding bin 16 is formed with a second discharge port. The end of the seeding wheel 20 extends out of the seeding bin through the shaft 17 and is connected to the driven wheel 2 19 for synchronous rotation. The seeding wheel 20 includes a wheel body, and gaps for pre-storing seeds are formed at intervals on the peripheral wall of the wheel body. During the rotation of the wheel body, the seeds in the gaps fall into the second discharge port below in an orderly manner, and the phenomenon of repeated sowing and missed sowing is reduced in cooperation.

[0043] like Figure 2 , Figure 4 , Figure 7As shown, in this example, an adjustment component is installed on the frame 3, and the adjustment component includes a hand wheel 24, a threaded rod 23, and a tube clamp 22. The threaded rod 23 is horizontally arranged and threadedly connected to the frame 3. The head end of the threaded rod 23 is fixed to the hand wheel 24 and the tail end is pivotally connected to the tube clamp 22. A seeding tube 21 is longitudinally installed at the second discharge port. Seeds flow into the seeding tube at the second discharge port. The seeding tube 21 passes through the cavity of the tube clamp 22. The seeding tube is formed of a material such as plastic. The hand wheel is turned to make the threaded rod 21 extend forward or retract backward, thereby tilting the seeding tube toward the seed pressing roller to shorten the distance between the two, or tilting the seeding tube away from the seed pressing roller to increase the distance between the two, so as to adapt to sowing in different situations.

[0044] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, in this example, a driving assembly 12, a mounting plate 9, and a workbench 1 are added, wherein the frame 3 is located at the top surface of the top plate in the workbench 1, and the driving assembly includes a driving motor 26 and a friction wheel 27. The friction wheel is a wheel body formed of a material with a large friction coefficient. The driving motor 26 adopts a double-output shaft motor. The driving motor 26 is fixed on the mounting plate 9 and the friction wheel 27 is fixed at the output end of the driving motor 26. The friction wheel 27 abuts against the bottom surface of the top plate in the workbench 1, and the friction wheel moves along the workbench. A support rod is fixed at the side of the mounting plate 9, and a roller 10 is installed at the top of the support rod. The roller 10 is located above the driving motor 26 and is located in a movable groove formed on the top plate of the workbench 1. The corresponding guide rail 8 can be placed in the movable groove according to the structure of the roller.

[0045] The mounting plate 9 is located below the top plate in the workbench 1, and threaded rods 11 are fixed at the four corners of the mounting plate 9. The threaded rods 11 pass through the holes formed on the layering strips 7 in the frame 3 and are fixed by nuts 15. When in use, the driving motor is started, and the driving motor drives the friction wheel to rotate. The friction wheel moves along the bottom surface of the top plate in the workbench, and the roller moves along the moving groove synchronously. The movement of the mounting plate synchronously prompts the frame to move along the top plate, and a seedling hole tray 2 is placed on the top plate. The protrusions 14 in the seed pressing roller make pits appear on the substrate surface of the seeding hole tray, and the seeds flowing out of the seed tube fall into the pits, and then are compacted by a driven wheel to improve the degree of automation.

[0046] A travel switch 28 cooperating with the roller can be installed in the movable groove, and the travel switch 28 is connected to the driving motor. When the roller abuts against the travel switch, the driving motor stops in time, which is convenient for replacing the seedling hole tray.

[0047] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
