Abstract
Description
Technical Field
[0001] The utility model belongs to potato precision sowing equipment, mainly relates to a double-cavity air-suction type micro-potato precision sowing device. Background Art
[0002] At present, the existing potato planting equipment is mainly divided into mechanical potato planters and pneumatic potato planters, but both of them have mainly conducted extensive research on whole potatoes and cut potatoes, and are not suitable for the planting of micro potatoes. The planting of micro potatoes has only remained in theoretical research and has not been applied to actual planting operations.
[0003] The current problem is that since mini potatoes are smaller than whole potatoes and cut potatoes, the potato planters currently developed are for whole potatoes and cut potatoes. Using them for mini potatoes will result in a high reseeding rate of mini potatoes, causing certain economic losses. At the same time, the existing potato planters have low working efficiency and cannot meet the needs of large-scale potato planting. The use of air-suction potato planters can greatly improve the planting efficiency of mini potatoes. In addition, the double-chamber potato planter can realize the large-ridge double-row potato planting agronomy, and can complete the planting of two rows of potatoes at one time.
[0004] So far, no micro-tuber sowing device has been successfully developed that can efficiently and accurately complete the micro-tuber sowing work. Summary of the invention
[0005] The purpose of the utility model is to address the problems existing in the above-mentioned prior art, combine the agronomic requirements in the process of micro-tuber sowing, and develop and design a double-chamber air-suction micro-tuber precision sowing device to provide an efficient and precise sowing device for micro-tuber sowing; improve the potato yield per unit area, simplify the micro-tuber sowing process, and complete the micro-tuber sowing work that meets the agronomic requirements of large ridges and double rows at one time, providing a feasible device for micro-tuber sowing.
[0006] The object of the present utility model is achieved as follows: A left potato discharging cover and a right potato discharging cover are respectively arranged on the left and right sides of the double-chamber potato discharging device housing and are connected by bolts. A left potato filling port is installed at the upper end of the left potato discharging cover, a quick potato discharging device is installed at the lower left side of the left potato discharging cover, and a working observation window is installed at the upper right side of the left potato discharging cover; A right potato filling port is installed at the upper end of the right potato discharging cover; A double-chamber potato discharging device housing driving end cover is installed at the lower end of the double-chamber potato discharging device, and a large bevel gear and a small bevel gear are installed inside. The large bevel gear is installed on the potato discharging shaft, and left and right potato discharging disks and potato stirring wheels are installed on both sides of the potato discharging shaft; A small bevel gear shaft is installed on the small bevel gear; A wear-reducing seal ring pressing disk is installed inside the left and right potato discharging disks, and a wear-reducing seal ring is installed inside the wear-reducing seal ring; Potato cleaning knives are installed at the lower outer ends of the left and right potato discharging disks, and potato stirring wheels are installed outside; 20 micro potato suction holes are respectively opened on the left and right potato discharging disks.
[0007] The present utility model makes full and reasonable use of the characteristics that micro potatoes have a relatively low weight and are easily adsorbed by negative pressure. Under the action of negative pressure, the micro potatoes are adsorbed onto the suction holes of the potato discharging disk. The micro potatoes adsorbed onto the potato discharging disk are separated from the micro potato population under the drive of the potato discharging disk. As the potato discharging disk rotates, the micro potatoes are brought to the outlet. Under the action of the potato cleaning knife, the connection between the negative pressure and the micro potatoes is disconnected, and the micro potatoes enter the seed potato pipe; The potato stirring wheel can fully disturb the micro potatoes in the population, facilitating the adsorption of micro potatoes; The double-chamber potato discharging device can achieve the sowing of micro potatoes in two rows on a large ridge at one time, simplifying the operation process. The whole device has the characteristics of novel, unique, reasonable structure, high operation efficiency, reliable use and few faults. Description of the Drawings

[0013] The implementation scheme of the present utility model will be described in detail below with reference to the accompanying drawings. A double-chamber air-suction type micro-potato precision potato planter is provided with a left potato discharging cover 11 and a right potato discharging cover 5 on the left and right sides of a double-chamber potato discharging device housing 3 respectively, which are connected by bolts. A left potato filling port 1 is installed at the upper end of the left potato discharging cover 11, a quick potato discharging device 10 is installed at the lower left side of the left potato discharging cover 11, and a working observation window 2 is installed at the upper right side of the left potato discharging cover 11; a right potato filling port 4 is installed at the upper end of the right potato discharging cover 3; a transmission end cover 18 of the double-chamber potato discharging device housing is installed at the lower end of the double-chamber potato discharging device housing 3, and a large bevel gear 17 and a small bevel gear 16 are installed inside. The large bevel gear 17 is installed on a potato discharging shaft 13, and a left potato discharging plate 8, a right potato discharging plate 7 and a potato stirring wheel 12 are installed on both sides of the potato discharging shaft 13; a small bevel gear shaft 6 is installed on the small bevel gear 16; a loss reduction sealing ring pressing disc 14 is installed inside the left potato discharging plate 8 and the right potato discharging plate 7, and a loss reduction sealing ring 15 is installed inside the loss reduction sealing ring pressing disc 14; a potato cleaning knife 9 is installed at the lower outer ends of the left potato discharging plate 8 and the right potato discharging plate 7; 20 micro-potato suction holes are respectively formed in the left potato discharging plate 8 and the right potato discharging plate 7.
[0014] During operation, the micro-tubers enter the left tuber discharging cover 11 and the right tuber discharging cover 5 through the left tuber filling port 1 and the right tuber filling port 4 and into the tuber discharging covers. The negative pressure fan is connected to the negative pressure inlet on the double-chamber tuber discharging housing 3 and enters the left and right sides of the double-chamber tuber discharging housing through a tee. Under the action of the negative pressure fan, the micro-tubers are negatively adsorbed onto the tuber suction holes of the left tuber discharging tray 11 and the right tuber discharging tray 7. As the tuber discharging trays move, the micro-tubers are separated from the seed tuber group. Driven by the tuber discharging trays, the micro-tubers are transported to the outlet of the double-chamber tuber discharging device. Under the action of the tuber cleaning knife 9, the connection between the micro-tubers and the negative pressure is blocked, and the tubers are discharged under the action of gravity, meeting the operation requirements of precision seeding in two rows on a large ridge at one time. After the work is completed, the sown micro-tubers can be taken out from the quick tuber discharging device 10, facilitating the next micro-tuber seeding. Compared with the traditional single-row tuber seeder, this seeder can complete the workload of the traditional seeder twice at one time, ensuring the production efficiency of the device. Fixing the loss-reducing sealing ring 15 with the loss-reducing sealing ring pressing plate 14 can effectively reduce the loss of negative pressure and energy consumption. Installing the tuber stirring wheel 12 can disturb the micro-tuber population, increase the fluidity of the micro-tuber population, and facilitate the adsorption of micro-tubers.
