Drum-type double-row pneumatic seed metering device for potato planter

Abstract

The invention belongs to the technical field of potato planting equipment and particularly relates to a drum-type double-row pneumatic seed metering device for a potato planter. The drum-type double-row pneumatic seed metering device is composed of a shell (1), a drum (2), a seed feeding hopper (3), a seed box (4), shaft sleeves (5), seed guide devices (6), suction nozzles (7) and air outlets (8), wherein the drum (2) is mounted in the shell (1) through the shaft sleeves (5) arranged at the ends of the two sides of the drum (2); the seed feeding hopper (3) is arranged at one side of the drum (2) and the seed guide devices (6) are arranged at the other side of the drum (2); the seed box (4) is arranged just under the drum (2); the suction nozzles (7) are formed at the surface of the drum (2); and one air outlet (8) is further formed in the connection part of the end at one side of the drum (2) and one shaft sleeve (5). The drum type double-row pneumatic seed metering device for the potato planter provided by the invention has the beneficial effects that the structure is compact, the use is convenient and potato seeds are uneasily damaged; the empty hole rate of planting is reduced and the seeds can be sowed in two rows, and therefore, the drum type double-row pneumatic seed metering device brings great convenience to a user.

Description

technical field [0001] The technology of the invention belongs to the technical field of potato planting equipment, and in particular relates to a drum-type double-row pneumatic seed metering device for a potato planter. Background technique [0002] Potatoes, also known as artichokes, potatoes, and yam eggs, are one of the world's most important food crops. The main producing areas of potatoes in China are the Southwest Mountains, Northwest, Inner Mongolia and Northeast. The planting area of ​​potatoes in my country is about 45 million mu in recent years, ranking first in the world. Potatoes are cultivated in all provinces (cities) of the country, especially in the cold and cool areas of the north and the mountainous areas of the southwest. Potatoes are comprehensive in nutrition, high in value, durable and long in storage time, and are good for rural people to improve food structure and residents to maintain health food. [0003] Due to the wide range of planting of pot...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing potato planting methods are mainly manual operations, which seem powerless when faced with large-scale potato planting

However, the existing potato planting machinery has a complex structure, a large volume, and high operating costs, which can improve efficiency for potato planting operations, but due to the high cost, the increase in economic benefits is not obvious, and due to the large size, the average farmer On the one hand, there is no financial ability to purchase, on the other hand, the requirements for potato growing areas are relatively high

[0005] There are many factors restricting the planting efficiency of potato planters, among which the potato seeding device is the most important point, and the previous potato seeding methods include potato clip type, acupuncture type and chain spoon type, etc., due to the potato clip type and Acupuncture type has a high reseeding rate and missed seeding rate, and is rarely used at present, while the chain spoon type has a complex structure and a large volume, and the parts are more likely to collide and damage potato seeds during movement, and due to the limitation of the seed picking method, it is easy to produce cavitation phenomenon , so a potato seeding device with simple structure, small size, not easy to damage potato seeds, and reduce the planting hole rate is particularly important.
