Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to soil fertilization and improvement equipment. Background Art

[0002] Soil fertilization and improvement is a vital part of agricultural production. It aims to improve soil structure and soil fertility through scientific and reasonable fertilization methods, thereby promoting the growth and development of crops. The combination of bacterial fertilizer and chemical fertilizer can improve soil fertility and improve soil structure. Bacterial fertilizer maintains the environment and activity of the bacterial community, promotes the reproduction of beneficial bacteria in the soil, inhibits the growth of miscellaneous bacteria, thereby improving the physical and chemical properties of the soil and reducing soil compaction, acidification, salinization and other problems. At the same time, bacterial fertilizer can also activate fixed nutrients, improve the effectiveness of soil nutrients, and further enhance soil fertility, which has a great effect on soil improvement. Bacterial fertilizer and chemical fertilizer need to be applied to different soil layers. The existing method is to apply bacterial fertilizer to the surface of the soil, and then apply chemical fertilizer to the deep soil layer. This method easily causes chemical fertilizer and bacteria to mix together, thereby inhibiting the activity of the bacteria, or changing the soil microenvironment, thereby adversely affecting the survival and reproduction of the bacteria. The current stratified fertilization requires agricultural machinery to be carried out in multiple steps, so it is more troublesome in the process of soil improvement. Summary of the invention

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] 1. The tractor can drive the device to move in the farmland, and the output end of the diesel engine can drive the drive shaft to rotate. During the movement, the drive shaft can drive multiple soil-breaking wheels on the outer wall to rotate, so that the compacted land can be broken and reclaimed. At the same time, multiple soil-breaking rods spirally arranged on the drive shaft can break up the soil clods during the rolling process, so that the soil can be loosened before fertilization, thereby improving the air permeability of the soil on the one hand, preventing the soil from being too compact and causing poor air permeability, oxygen cannot enter the soil layer, thereby affecting the normal breathing and growth of plant roots, and on the other hand, making it easier for water to penetrate into the soil, so that the plant roots can easily absorb water.

[0059] 2. The three deep plowing columns in the deep plowing mechanism are driven to gradually descend by the hydraulic cylinder, so that the tip of the deep plowing column first penetrates into the soil, and then as the deep plowing column continues to penetrate, it can dig multiple vertical grooves in the soil. The deep plowing column can also drive the transverse shovel column to follow the movement. When the deep plowing column descends to the deep layer of the soil, the transverse shovel column can be used to dig transverse grooves in the soil along the moving direction of the equipment. At the same time, the synchronous pulley is driven to rotate by the driving shaft, and then the double-groove pulley and the linkage column are driven to rotate by the transmission belt, so that the turntable can be driven to rotate continuously, so that the turntable can drive the sliding rod to slide back and forth in the sliding hole column. When the sliding hole column rises, it can push the lifting column to rise, and the lifting column can drive the closing cover to rise together, so that it is separated from the sealing ring, and then the fertilizer box The fertilizer in the fertilizer can enter the pressure box through the round hole in the ring sealing ring. At the same time, the sliding hole column will drive the piston column to rise, so that air can be extracted from the outside through the one-way valve. When the sliding hole column descends, it can drive the piston column to descend and press the air into the pressure box. Then the fertilizer can be connected with the air and transported to the fertilizer discharge pipe by the hose, and then discharged through the multiple fertilizer delivery columns in the horizontal shovel column, so as to prevent the soil from blocking the fertilizer delivery column while transporting the fertilizer. In the process of deep tillage and further outputting the soil by deep tillage mechanism, the fertilizer is applied to the deep soil through multiple fertilizer delivery columns, and the screw can be driven to rotate by the rotating block according to the needs, so as to adjust the height of the horizontal shovel column, so that the fertilizer application depth can be adjusted according to the difference of soil and plants, so that the fertilization improvement device can be used under a variety of soil conditions.

[0060] 3. The double-groove pulley can synchronously drive the transmission belt 2 to roll, so that the other end of the transmission belt 2 can drive the synchronous pulley 2 and the rotating roller to rotate, and then drive the conveyor belt and multiple digging half-cylinders on the outer wall to circulate and roll. When the digging half-cylinder is at the bottom of the conveyor belt, the surface soil can be excavated and scooped into the digging half-cylinder. As the digging half-cylinder slides and rises along the surface of the vertical plate, the digging half-cylinder will slide against the inclined block, thereby driving the inclined block and the sliding plate to slide at the bottom of the discharge cavity plate. The sliding plate can drive the comb plate to move and separate the square blocks, and the gap between the square blocks It can facilitate the discharge of fertilizers, and then the bacterial agent and organic fertilizer in the bacterial fertilizer box fall into the digging half-cylinder through the discharge cavity plate. At the same time, due to the meshing and rotation of the tooth column and the rack plate, the mixing shaft is driven to mix the bacterial agent with the organic fertilizer and the surface soil. When the digging half-cylinder is turned over to the opening facing downward, the soil mixed with the bacterial agent can be sprinkled on the soil surface again, so as to facilitate the application of bacterial fertilizer to the surface soil, and the equipment can be used for layered fertilization with the chemical fertilizer applied in the deep soil, and the two will not be mixed, so as to avoid the loss of activity of the microorganisms in the bacterial fertilizer, thereby improving the soil improvement effect.
