Mechanical corn hole punching deep fertilization topdressing device

Abstract

The invention belongs to the technical field of agricultural machines, and particularly relates to a mechanical corn hole punching deep fertilization topdressing device.The device is composed of a main beam frame (1), a power transfer mechanism, a rail determination mechanism and a hole punching fertilization device.According to the mechanical corn hole punching deep fertilization topdressing device, a crank block is driven by a transmission shaft to rotate, the hole punching fertilization device is further driven to achieve the topdressing process of hole punching in soil, opening for fertilization, soil leaving and closing, the process of manual topdressing is replaced, time and labor are saved, and work efficiency is improved.The stretching-in length of a fertilizer shaft plug in a fertilizer discharge shaft is changed to change the topdressing amount, and a quantitative topdressing effect is achieved.The hole punching deep fertilization topdressing mode is adopted, scratches to the roots of corn are reduced, fertilizer is saved, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a mechanical device for deeply applying topdressing fertilizer in corn holes. Background technique [0002] Mid-term topdressing of high-stalk crops such as corn is an important part of agricultural field management. For a long time, most of the topdressing of corn has been done manually, which not only has high labor intensity and low production efficiency, but also spreads the fertilizer on the surface, which has low utilization efficiency and serious environmental pollution. In order to improve the operation efficiency, people have developed some simple corn topdressing machines, which have improved the utilization efficiency of fertilizers to a certain extent and reduced the pollution to the environment. [0003] A patented knapsack fertilizer topdressing machine (ZL201220415961.5) adopts manual carrying operation, the operator shakes the handle on...

Problems solved by technology

[0004] However, the above-mentioned knapsack topdressing machine relies on manual operation completely. Although the efficiency of fertilization is improved compared with the traditional planing pit, the work intensity is still relatively large, and the utilization rate of fertilizer applied to the surface is low, which pollutes the environment; the above-mentioned self-propelled The small topdressing machine advances by manpower driving the ground wheel, the machine has a large walking resistance, and the manual work is intensive. A row of fertilizer is applied between two rows of corn, and the distance between the fertilizer and the corn plant is large, and the effect of topdressing is not obvious; the double plow intertillage topdressing machine can complete it at one time. Three lines of corn topdressing can greatly improve work efficiency, and the amount of fertilizer can also be adjusted according to demand. However, this topdressing machine is only suitable for topdressing corn seedlings, and it is not suitable for topdressing in the middle and late stages of corn growth. It is easy to break corn plants and affect corn production.
