Synchronization fertilizer apparatus of sowing machine

Abstract

The invention discloses a synchronous device for a drill, comprising a seed and fertilizer combination box. A seeding wheel and a fertilizing wheel are respectively arranged at the bottom of the seed and fertilizer combination box. A movable cover plate is arranged under the fertilizing wheel of the seed and fertilizer combination box. The movable cover plate is provided with a crank shaft at the top which is used to control the movement of the movable plate. The crank shaft is connected with a rolling wheel at the top. A seeding wheel shaft of the seeding wheel is provided with a cam which has at least a double wedge arranged at the rolling shaft. The movable cover plate arranged under the fertilizing wheel of the invention is usually under the status of closing the fertilizing opening. When the double wedge of the cam rotating to the crank shaft, the double wedge moves the crank shaft to rotate and bring along the rotation of the movable cover plate so as to open the fertilizing opening and let the fertilizer fall off. When the double wedge leaves the crank shaft, the crank shaft returns and makes the movable cover plate return to close the fertilizer opening and stop fertilizing. Meanwhile, seeding starts. Since the drill is moving forward, the seeding opening just rotates to the fertilizing opening when seeding, realizing quantified and positioned seeding and fertilizing.

Description

technical field [0001] The invention relates to a sowing and fertilizing device for a seeder, in particular to a synchronous fertilizing device for a seeder. Background technique [0002] In agricultural production, seeding and fertilizing operations basically use seeding and fertilizing machines, which can improve labor efficiency and reduce labor intensity. But now commonly used seeding and fertilizing machines all adopt drill fertilization, and for crops with far distances, such as sunflower, etc., it causes a waste of fertilizer. Fixed-point fertilization cannot be carried out at the seeding place, and it is difficult to achieve synchronous sowing and fertilization. In order to increase food production, it is necessary to apply fertilizer in the sowing ridge, sowing anywhere in the ridge can make there be sufficient fertilizer under the seeds, which causes a waste of fertilizer, increases the cost of use, and improves the quality of crops. Production costs, reducing th...

Problems solved by technology

However, the commonly used seeding and fertilizing machines now use drill fertilization, and for crops with a long distance between plants, such as sunflower, it causes a waste of fertilizer

Fixed-point fertilization cannot be performed at the seeding place, and it is difficult to achieve simultaneous seeding and fertilization

In order to increase food production, it is necessary to apply fertilizer in the sowing ridge, sowing anywhere in the ridge can make there be sufficient fertilizer under the seeds, which causes a waste of fertilizer, increases the cost of use, and improves the quality of crops. Production costs, reducing farmers' real income
