Description

Technical Field

[0001] This utility model relates to a fertilizer plow structure for a peanut rotary tillage planter, belonging to the field of peanut planting machinery technology. Background Technology

[0002] Peanut planters are a commonly used type of agricultural machinery. my country ranks second in the world in total peanut planting area and first in total peanut production, and its mechanized peanut planting technology has made significant progress. Currently, existing peanut planters can complete ridging, furrowing, fertilization, sowing, covering, compaction, drip irrigation tape laying, spraying (herbicides), mulching, covering the mulch with soil, and self-cutting in one operation. Examples include Chinese patents CN2021110538097, CN2021110776894, and CN 2024106005407. With the combined use of rotary tillers and peanut planters, the planting efficiency is greatly improved by tilling first and then planting. However, the fertilizer plows used for furrowing and fertilization in existing peanut planters are generally disc plows or moldboard plows with the plow tip pointing forward. The plow tip is too close to the rotary tiller, making it easy for them to collide. The fertilizer discharge channel is not aligned with the fertilizer plow, causing poor fertilizer flow and blockages. In addition, existing fertilizer plows cannot be used in conjunction with rotary tillage for ridging. Since the rotary tiller is in front, it can complete secondary soil pulverization, improve the soil pulverization rate, ensure that the peanut ridges are free of soil clods, and provide an ideal seedbed for peanut growth. At the same time, timely ridging effectively retains moisture in the peanut ridges, providing the necessary water for peanut sowing, germination, and growth. It can also ensure that the center line of the fertilizer plow corresponds to the center line of the peanut ridge surface, achieving a flat fertilizer surface and ensuring that the peanut seedlings on both sides receive fertilizer evenly. If the fertilization is uneven, the uneven fertilizer will not meet the normal growth needs of peanuts in the early stages of growth. Utility Model Content

[0003] The purpose of this utility model is to provide a fertilizer plow structure for a peanut rotary tiller, which avoids the plow tip from colliding with the rotary tiller in front, enables timely ridging and water retention, ensures that the center line of the fertilizer plow corresponds to the center line of the peanut ridge, provides balanced fertilization, guarantees the fertilizer needs of peanuts during growth, ensures sowing quality, and ensures that the fertilizer discharge channel is on the same vertical line as the fertilizer plow, so that the fertilizer path is unobstructed and avoids blockage. This solves the above-mentioned problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A fertilizer plow structure for a peanut rotary tiller includes a frame, a fertilizer box, a rotary tiller, a fertilizer applicator, a fertilizer funnel, and a fertilizer plow. The rotary tiller is located below the frame, the fertilizer box is located above the rotary tiller, and the fertilizer plow is located behind the rotary tiller. The fertilizer applicator is located at the bottom of the fertilizer box. The key feature is that the fertilizer applicator is directly connected to the fertilizer plow via the fertilizer funnel, and the fertilizer box, fertilizer applicator, fertilizer funnel, and fertilizer plow are aligned on a vertical line. The fertilizer plow is welded from a square tube and a right-angled fan-shaped plowshare, with the plow tip of the right-angled fan-shaped plowshare facing the rear of the rotary tiller. The right-angled fan-shaped plowshare is welded from a left right-angled fan-shaped plate, a right right-angled fan-shaped plate, and a rectangular arc-shaped base plate. The plates are parallel to each other. The arc of the fan-shaped sides of the left and right right-angled fan-shaped plates is the same as the curvature of the rectangular arc base plate. The fan-shaped sides of the left and right right-angled fan-shaped plates are respectively welded perpendicularly to both sides of the rectangular arc base plate, forming a U-shaped fertilization channel. One right-angled side of the left and right right-angled fan-shaped plates is respectively welded to both sides of the bottom outlet of the square tube. The rectangular arc base plate is also welded to the bottom side of the bottom outlet of the square tube. The fertilization pipe formed by the square tube and the U-shaped fertilization channel together form the fertilizer discharge channel of the fertilizer plow. The U-shaped opening of the U-shaped fertilization channel faces away from the rotary tiller. The rectangular arc base plate of the fertilizer plow is set at an angle to the ground, and the square tube is set perpendicular to the ground.

[0006] A ridging side plate is installed between the rotary tiller and the fertilizer plow. The ridging side plate rids the soil that has been pulverized by the rotary tiller, and the center line of the fertilizer plow corresponds to the center line of the ridged surface.

[0007] The fertilizer discharger has a discharge port at its bottom, which is directly connected to the upper opening of the fertilizer funnel. The lower opening of the fertilizer funnel is connected to the discharge channel of the fertilizer plow.

[0008] The frame is equipped with a fertilizer plow mounting base, and the square tube of the fertilizer plow is fixed on the fertilizer plow mounting base.

[0009] The ridging side plate is a rectangular plate arranged at an inclination angle of 120 degrees, and is fixed to the rear frame of the rotary tiller by bolts.

[0010] The fertilizer plow has a large opening at the bottom of its square tube, resulting in more even fertilizer discharge.

[0011] This invention utilizes a rotary tiller to pulverize the soil a second time, followed by ridging operations using the ridge-forming side plates. The right-angled fan-shaped plowhead of the fertilizer plow directly cuts wide furrows on the ridge surface. Fertilizer flows vertically from the fertilizer bin through the fertilizer dispenser and funnel to the fertilizer plow, ensuring unobstructed fertilizer flow, preventing blockages, and providing even fertilization to guarantee appropriate fertilization at each growth stage of peanuts. Because the fertilizer is spread evenly on the ridge surface, it ensures that both rows of peanuts can absorb the fertilizer evenly.

[0012] The beneficial effects of this utility model are: it avoids the collision between the tip of the fertilizer plow and the rotary tiller in front, timely ridging and water retention, the center line of the fertilizer plow corresponds to the center line of the peanut ridge, the fertilizer is applied evenly, the fertilizer needs during peanut growth are guaranteed, the sowing quality is guaranteed, the fertilizer discharge channel is on the same vertical line as the fertilizer plow, the fertilizer path is unobstructed and blockage is avoided.
