Chinese cabbage precision compound seeder

Abstract

The invention discloses a pakchoi precision compound seeder, which comprises a rotary tillage and ridge system, a pneumatic system installed at the middle position of the upper part of the rotary tillage and ridge system, and hooked to the rear part of the rotary tillage and ridge system. The seeding system and two sets of fertilizer discharge systems symmetrically installed on the rotary tillage and ridge system. The tension degree of the synchronous belt can be controlled by adjusting the parallel position of the small synchronous pulley; the symmetrical configuration mode of double bearings can be used to quickly adjust the installation angle of the shaft center of the pulley and improve the installation accuracy of the synchronous belt drive; it is connected by a telescopic cross universal coupling The power is transmitted to the fan, which removes the installation position restriction of each transmission device; the curve of the sliding knife of the opener is conducive to sliding cutting and breaking the soil, reducing the power consumption of the planter, and simplifying the control method of the sowing depth; The phenomenon of random rolling, bouncing, clogging and adhesion of seeds improves the uniformity of plant spacing; it can simultaneously realize joint operations such as rotary tillage, fertilization, ridging, ditching, sowing, soil covering, and suppression.

Description

technical field [0001] The invention belongs to the technical field of crop sowing equipment, and in particular relates to a pakchoi precision compound seeder. Background technique [0002] The Yangtze River Basin in my country is suitable for planting pakchoi. Both seeds belong to the category of small-size seeds. With the rapid economic development, people's demand for pakchoi is increasing year by year. Its mechanized production can complete efficient planting operations and solve the demand problem. In mechanized production, the sowing link is the key, especially the joint precision sowing technology is the key research content of the current research institute. [0003] At present, domestic seeders matched with four-wheel tractors have the characteristics of compact structure, reliable use, and large social holdings, but most of the machines have single functions and can only be used for sowing operations. If you want to carry out rotary tillage, furrowing or sowing an...

Problems solved by technology

[0003] At present, domestic seeders matched with four-wheel tractors have the characteristics of compact structure, reliable use, and large social holdings, but most of the machines have single functions and can only be used for sowing operations

If you want to carry out rotary tillage, furrowing or sowing and fertilization operations, you need to hook up the corresponding equipment on the return trip. As a result, not only the labor intensity, the number of tractors entering the ground and energy consumption will be increased, but also the equipment investment will be large, which is not conducive to social resources. Take advantage of

There are also seeders improved from other models, which have problems such as large seeding volume, high seed damage rate, and poor uniformity. They are not suitable for sowing Chinese cabbage, especially for high-efficiency and precise seeding operations, and it is difficult to achieve high yield and high efficiency. Production
