Problems solved by technology

[0002] At present, the tobacco planting technology in Southwest China has been widely used. Subsoiling and fertilization are often used to carry out large-scale operations on cultivated land. However, in the cultivation of cultivated land in recent years, the quality of tobacco planting has begun to decline year by year. The investigation It was found that the soil quality of the soil has changed, the soil compaction is serious, and the cultivation of tobacco has been seriously affected
[0003] Under the situation that the benefits of common farming methods are gradually decreasing, we began to look for farming methods that can damage the soil compaction and hard plow bottom. When deep loosening the soil with a depth of 30 cm, it can only loosen the soil and will not damage the soil. Plowing the bottom soil to the surface can improve the soil's water storage and moisture retention capacity, so it can be used as a farming method to increase tobacco production. The problem of sticky compaction and insufficient soil fertility needs to be operated by different farming machinery, which leads to low efficiency of soil improvement and the inability to achieve precise control of fertilization steps, which is not conducive to tobacco planting and reduces farming efficiency

Abstract

The invention belongs to the technical field of fertilization, and is specifically a precision-controlled vertical screw type subsoiling fertilizer applicator, including a fertilizer box and a subsoiling shovel; There is a Hall sensor fixedly connected to the inside of the card slot. By using the Hall sensor associated with the single-chip microcomputer, the single-chip microcomputer will feed back the action to the servo motor for speed regulation according to the speed in the Hall sensor, so that the fertilization amount can be controlled. Precise control makes the fertilization rate slow down as the tractor speed slows down to ensure proper fertilizer application, and when the servo motor starts to drive the drive shaft to rotate, the drive shaft drives the agitating blades, conveying auger and throwing tray at the same time Rotate synchronously, and under the action of centrifugal force, move through the open end of the spinner box and the open end of the subsoiling shovel into the subsoiled soil to realize duplex operation and complete the subsoiling and fertilization work at one time, which can effectively reduce the tractor The number of times to enter the field to work, improve the efficiency of farming.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to a precision-controlled vertical screw type subsoiling fertiliser. Background technique [0002] At present, the tobacco planting technology in the southwest has been widely used, and sub-soaking and fertilization are often used to carry out large-scale operation of cultivated land. However, in the cultivation of cultivated land in recent years, the quality of tobacco planting has begun to decline year by year. It was found that the soil quality of the soil had changed, the soil was severely compacted, and the cultivation of tobacco had been seriously affected. [0003] Under the situation that the benefits of common farming methods are gradually declining, we began to seek farming methods that can destroy soil compaction and hard plough bottom. Ploughing the bottom soil to the surface layer can improve the water storage and moisture retention capacity of the soil, so it ca...
