An automatic power precise control amount spreading mechanism

Abstract

The invention discloses an automatic power accurate quantity-controlling and sowing mechanism. The automatic power accurate quantity-controlling and sowing mechanism comprises two groups of acceleration mechanisms, knuckle bearings, oblique-pulling bars, a sowing box and a discharging adjusting gate, wherein the acceleration mechanisms are not less than three grades and are matched with wheels; the knuckle bearings are arranged at the tail ends of the acceleration mechanisms; the oblique-pulling bars are matched with the other ends of the knuckle bearings; the sowing box is matched with a vehicle body; the discharging adjusting gate is arranged on the inner side of the sowing box and the top of the discharging adjusting gate is hinged with the sowing box; and the oblique-pulling bars movably penetrate through the sowing box and is matched with the discharging adjusting gate. The automatic power accurate quantity-controlling and sowing mechanism provided by the invention provides automatic power through the movement of the wheels, and the automatic power is subjected to multi-graded acceleration and then is transmitted to the knuckle bearings, so that ordered actions of the discharging adjusting gate are realized and the discharging is relatively uniform; and furthermore, fertilization and sowing can be integrated and a sowing amount is adjusted according to a moving speed, so that the automatic power accurate quantity-controlling and sowing mechanism better accords with practice.

Description

technical field [0001] The invention relates to a spreading mechanism, in particular to a spreading mechanism with automatic power and precise volume control, belonging to the technical field of agricultural machinery. Background technique [0002] The planting object of the seeder is the seed of the crop or the coated seed made into a pellet; it can be divided into three types according to the sowing method: the vacuum seed sower, the drill and the hole sower; The planter can precisely control the seeding rate, hole (plant) distance and sowing depth. The pneumatic seeding precision seeder developed in the 1970s, its seed metering device (air suction type, air pressure type or air blowing type) uses positive pressure or negative pressure airflow to discharge a row of seeds at certain intervals to achieve single seed precision seeding. Compared with the traditional mechanical seed metering device, it has the characteristics of accurate seeding rate and no damage to seeds; in...

The pneumatic seeding precision seeder developed in the 1970s, its seed metering device (air suction type, air pressure type or air blowing type) uses positive pressure or negative pressure airflow to discharge a row of seeds at certain intervals to achieve single seed precision seeding. Compared with the traditional mechanical seed metering device, it has the characteristics of accurate seeding rate and no damage to seeds; in addition, there is a mechanical precision seed metering device; it is a suspended 6-row row crop seeder with a fertilization device, which can be used for Drill sowing and hole sowing of row crops such as soybeans, corn and sorghum; but the above-mentioned sowing seed accuracy is only achieved by controlling the time interval, and cannot be adjusted according to the specific progress; Occurs in small quantities
