[0002] Tuber crops are important food crops, cash crops and feed crops in many regions, contributing significantly to regional economic development and becoming an important pillar industry. Traditional tuber crop planting mainly relies on manual sowing and fertilization, which is labor-intensive and inefficient. Traditional tuber seeders mainly use chain cup spoon seeders, which take up a large space and require certain manual assistance; the feeding and fertilization mechanisms of traditional tuber seeders are independent of each other and lack relevance. Utility Model Content

[0003] The utility model aims to provide a disc-type feeding and fertilizing linkage mechanism for agricultural tuber crops, so as to solve the problems in the background technology.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a disc-type feeding and fertilizing linkage mechanism for agricultural tuber crops, including an active dial, a feeding groove wheel, a fertilizing groove wheel, a feeding tray, a fertilizing tray, a rotating shaft, a feeding shaft, a fertilizing shaft, a coupling, a thrust ring, a motor, and a bearing. The rotating shaft is located between the feeding shaft and the fertilizing shaft, the active dial is installed on the rotating shaft, the active dial is installed on the active dial, the feeding tray and the feeding groove wheel are installed on the feeding shaft, and the fertilizing shaft is installed on the fertilizing tray and the fertilizing groove wheel.

[0005] Preferably, the motor is connected to the rotating shaft via a coupling, and the rotating shaft is rigidly connected to the active dial.

[0006] Preferably, bearings are installed at both ends of the unloading shaft and the fertilizing shaft, the lower end bearing is fixed on the frame, and the upper end bearing has a locking function and is rigidly connected to the unloading groove wheel and the fertilizing groove wheel respectively. A thrust ring is installed on the unloading shaft and the fertilizing shaft for positioning, and a unloading tray and a fertilizing tray are installed above the thrust ring.

[0007] Preferably, the unloading tray and the fertilizing tray are each provided with a through hole, and the bottom is provided with four limiting columns, which cooperate with the limiting holes on the frame to prevent the tray and the frame from rotating relative to each other.

[0008] Preferably, the outer periphery of the unloading groove wheel and the fertilizing groove wheel is provided with a plurality of evenly distributed grooves, and when any groove of the groove wheel is aligned with the through hole on the tray, the seeds / fertilizers fall down.

[0009] Preferably, the bottom of the fertilizing groove wheel and the unloading groove wheel is provided with a groove engaged with the cylindrical pin on the active dial, and the active dial rotates one circle to drive the fertilizing groove wheel and the unloading groove wheel to rotate one groove, thereby completing one unloading / fertilization.

[0010] Compared with the prior art, the utility model provides a disc-type feeding and fertilizing linkage mechanism for agricultural tuber crops, which has the following beneficial effects:

[0011] In the utility model, the motor drives the active dial to rotate, so that the cylindrical pin on the active dial meshes with the slots on the feeding groove wheel and the fertilizing groove wheel in turn, thereby driving the two to rotate, so as to realize the conversion of the continuous rotation of the motor shaft into the intermittent unidirectional periodic rotation of the feeding groove wheel and the fertilizing groove wheel, and complete the linkage of feeding and fertilizing. The disc-type structure realizes the uniform spacing distribution of each feeding and fertilizing, and because there is a time difference in rotation, it is ensured that the positions where the seeds and fertilizers fall are not at the same point, but are not too far apart, which not only ensures that the seeds can absorb the nutrients of the fertilizer, but also prevents the seeds from burning due to excessive fertilizer. By adjusting the speed of the motor, the planting spacing of the seeds can also be controlled to meet the planting requirements of different seeds and different lands.
