Description

Technical Field

[0001] The invention relates to the technical field related to agricultural machinery, and in particular to a jet fertilization device for corn in the tillage period. Background Art

[0002] Corn is a row-till crop, and its root system is sensitive to soil and air. Therefore, row-tillage can be used to keep the soil loose, which is beneficial to the growth and development of summer corn. During the corn seedling stage, when root growth is the main focus, timely row-tillage and loosening of the soil and weeding can not only increase soil temperature, improve soil air and nutrient conditions, but also eliminate soil compaction caused by mechanical walking and human trampling during sowing, reduce the occurrence of diseases, insects and weeds in the corn seedling stage, promote the growth of the corn seedling root system, and enhance the ability to absorb water and nutrients. Therefore, in the process of planting corn, row-tillage is widely used as an important agricultural technology, and the loose soil after row-tillage is also a critical period for topdressing nitrogen fertilizer. Therefore, the current common method is to hang a granular fertilizer spreader on the tail of the cultivator, but the current common granular fertilizer spreaders are mostly through a wave The wheel completes the spreading operation. It is well known that the impeller-type spreading structure is a process of evenly scattering granular fertilizer upward and outward with the impeller as the center. It is well known that the width of the corn intertillage furrow is 70-95cm and the furrow depth is 30-50cm. The topdressing granular nitrogen fertilizer only needs to be spread in the furrow after tillage, and does not need such a large range as the impeller spreading. The main reason is that even the first intertillage seedling height is at least between 35-45cm, so the nitrogen fertilizer particles are bound to fall into the corn trumpet, which will cause burns to the trumpet seedlings of the jointing; and the other linkage spot-seeding structure, although it can completely point the granular nitrogen fertilizer into the furrow after tillage, the point-type fertilization will cause the granular fertilizer to be scattered more concentratedly in the furrow after tillage, affecting the absorption of corn.

[0023] A second rotating shaft 19 perpendicular to the inner wall of the driving box 11 is installed at the end surface of each positioning plate 12. The second rotating shaft 19 is rotatably connected to the driving box 11. The second rotating shaft 19 at the top passes through the driving box 11 and extends into the material dispensing cavity to dock with the material dispensing device.

[0024] The material distributing device includes a distributing barrel 20 connected to the second rotating shaft 19. The distributing barrel 20 is a cylindrical barrel structure with both ends sealed and can slide with the inner wall gap of the distributing chamber. Ventilation holes 21 are symmetrically opened on both sides of the distributing barrel 20.

[0027] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings:

[0028] First, the fan 9 is started to blow air toward the material distribution chamber, and then the tractor is started to drive the inter-cultivation frame 1 to move forward. During the movement, the roller 3 drives the driven sprocket 18 to rotate in a chain transmission manner through the chain. During the rotation, the driven sprocket 18 uses the positioning plate 16 and the positioning seat 15 to drive the entire eccentric rotation of the driving rod 14 with the first rotating shaft 17 as the center. The eccentrically rotating driving rod 14 uses the positioning plate 13 to drive the positioning plate 12 to make corresponding left and right swinging movements. During the swinging of the positioning plate 12, the entire material distribution barrel 20 and the air guide blade 22 are driven to make a linked swinging movement, thereby ensuring that the fertilizer blown out by the fan 9 is always spread within a small angle range, so that it can fall into the newly opened inter-cultivation furrow of the inter-cultivation coulter 5;

[0029] The frame of the tractor is lifted upward, so that the roller 3 is out of contact with the ground, and the third rotating shaft 23 is pulled to rotate under the action of the return spring 25, and at this time, the ratchet in the driven sprocket 18 also rotates along the pawl until the end face of the distributing barrel 20 directly docks with the discharge hole 10, and at this time, the granular fertilizer cannot pass through the discharge hole 10 into the distributing cavity, thereby achieving the purpose of self-closing; and when the driven sprocket 18 rotates, the pawl is meshed and stuck on the ratchet teeth of the ratchet, so the return spring 25 can be compressed to make the vent 21 and the discharge hole 10 dock and connect back and forth to achieve discharge;

[0030] When the distributing cylinder 20 rotates, it drives the stirring shaft 24 to rotate, thereby improving the fluidity of the granular fertilizer in the fertilizer storage box 6.
