Pneumatic type and cup-scoop type precision seed-metering device suitable for potatoes

Abstract

The invention belongs to the technical field of agricultural seeding machinery and relates to a pneumatic cup type and scoop type precision seed-metering device suitable for potatoes. The key point of the pneumatic type and cup-scoop type precision seed-metering device adopts a combined seed-metering mode of a pneumatic type and a cup-scoop type. The pneumatic cup type and scoop type precision seed-metering device is characterized by comprising an intermittent feeding mechanism, a seed box and a pneumatic type and cup-scoop type mechanism; a maltese mechanism and a seed transport chain form the intermittent feeding mechanism; a first gas chamber housing and a second gas chamber housing form a circular gas chamber housing through a bolt; a plurality of curved strip seed suction pipes are uniformly arranged in the circumference of the outer edge of the second gas chamber housing, a seed suction cup is connected to each of the seed suction pipes, bearing pedestals are mounted on two sides of the gas chamber housing, and a transmission chain wheel is fastened on each of the bearing pedestals through a bolt; a seed-metering shaft is a hollow shaft, the circular gas chamber housing is mounted on the seed-metering shaft, and a negative air flow enters the circular gas chamber housing through a gas inlet, so that the circular gas chamber is filled with negative pressure; and by virtue of the structural design, potato seeds on the seed suction cup lose the negative pressure suction at the moment and are fed dependent on the gravity. The pneumatic cup type and scoop type precision seed-metering device provided by the invention can realize simple grain precision seeding, and miss-seeding is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding machinery, and in particular relates to a pneumatic cup and spoon type precision seed metering device suitable for potatoes. Background technique [0002] At present, the potato is one of the main food and vegetable crops in my country. It has the characteristics of high and stable yield, strong adaptability, rich nutrition, both grain and food, and a wide range of uses. my country will start the strategy of turning potatoes into a staple food, and promote the processing of potatoes into staple foods such as steamed bread, noodles, and rice noodles. Potatoes will become another staple food besides rice, wheat, and corn. With the continuous increase of potato planting area, its market demand is also increasing. However, the sowing method of potatoes in my country is still dominated by manual or semi-mechanized operations, which not only has high labor intensity and low production effi...

AI Technical Summary

Problems solved by technology

The pneumatic cup and spoon type precision seed metering device has good adaptability to the seed potatoes with large individual differences in shape, and can effectively reduce the missed seeding caused by individual differences in shape, and at the same time solve the problem caused by the difference between seed potatoes when potato planters are working. The problem of mechanical damage caused by mutual collision and accumulation meets the requirements of potato planting with large differences in the shape of seed potatoes
