Pneumatic Cup Spoon Metering Meter for Potatoes

Abstract

The invention belongs to the technical field of agricultural seed sowing machinery and relates to a pneumatic cup spoon type precise seed sowing device applicable to potatoes. The key point is that a pneumatic type and cup spoon type combined seed sowing manner is adopted. The pneumatic cup spoon type precise seed sowing device is characterized by comprising an intermittent feeding mechanism, seed boxes and a pneumatic cup spoon mechanism. The intermittent feeding mechanism is formed by a grooved wheel mechanism and a seed conveying chain. A circular air chamber shell body is formed by a first air chamber shell body and a second air chamber shell body through bolts; a plurality of curved strip-shaped seed suction tubes are uniformly arranged at the circumferential direction of the outer edge of the second air chamber shell body, seed suction cups are connected onto the seed suction tubes, bearing seats are mounted at the two sides of the air chamber shell body, and transmission chain wheels are fastened onto the bearing seats through bolts; and a sowing axle is a hollow axle, the circular air chamber shell body is mounted on the sowing axle, negative-pressure airflow enters the circular air chamber shell body through an air inlet, the circular air chamber shell body is enabled to be full of negative pressure, seed potatoes on the seed suction cups are enabled to instantaneously lose negative pressure suction by using structural design, and seed sowing is realized by gravity. The pneumatic cup spoon type precise seed sowing device applicable to the potatoes can be used for realizing single-grain precise seed sowing and reducing seeding absence.

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 food and vegetable, and 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 ef...

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
