An integrated drill for soybean waterlogging-resistant cultivation

Abstract

An integrated row seeder suitable for flood-resistant soybean cultivation includes a walking mechanism, a rotary tillage mechanism, a ridging mechanism, a sowing mechanism, a fertilization mechanism, a ridge-opening mechanism, and a spraying mechanism. The sowing mechanism utilizes brush rollers to remove seeds adhering to the feeding rollers (excluding those in the seed discharge trough), preventing excess seeds from falling off. The flexible bristles of the brush rollers also prevent seeds from being crushed during rotation. The scraper blades have an adjustable angle to meet different scraping intensities. A ridging height adjuster adjusts the height of the ridging rollers relative to the ground to suit different land conditions. The ridge-opening mechanism ensures drainage between rows on the same ridge while saving space and improving land utilization. A fertilization mechanism is added above the rotary tillage mechanism, and a pesticide spraying mechanism is added behind the compaction wheel, allowing for fertilizer application and pesticide spraying simultaneously with rotary tillage, saving time in field management.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to an integrated row seeder suitable for waterlogging-resistant soybean cultivation. Background Technology

[0002] Modern soybean production is characterized by "high-density planting, large-scale operation, mechanization, and standardization." Soybean planters need to complete ridging, ditching, sowing, and fertilization in one operation, maximizing efficiency and minimizing disturbance to the field and soil damage. In my country's main soybean-producing areas, the growing season coincides with periods of heavy rainfall, leading to frequent waterlogging. Therefore, scientifically designed field drainage systems are crucial for successful ridge-based sowing and effective drainage, which is essential for waterlogging-resistant cultivation. Furthermore, appropriate planting density is key to high soybean yields. my country has a diverse range of soybean varieties, each with varying optimal planting densities. Insufficient row or plant spacing hinders ventilation and pod growth; excessive spacing leads to excessive vegetative growth, resulting in few or no pods, insufficient grain filling, and reduced grain weight. Therefore, soybean planters must allow for adjustable row and plant spacing.

[0003] Currently, soybean planters in my country can effectively improve work efficiency and save manpower. However, existing planting equipment has a drawback: it does not consider the integrated process of soybean planting and crop management; it also fails to adequately address the issue of waterlogging and drainage in the field; and during the soil covering process, it can easily compact the ground too much, affecting the germination rate.

[0004] To solve the above-mentioned technical problems, there is an urgent need for a precision seeder with adjustable plant spacing that can integrate ridging, fertilization, ditching, sowing, compaction, and watering to achieve high-yield and high-efficiency soybean cultivation with flood resistance.

[0056] The container and pump are mounted on the walking mechanism.

[0057] The beneficial effects of this invention are:

[0058] The seeding mechanism uses brush rollers to clean the seeds that are stuck to the feeding rollers except for the seed dispensing trough, preventing excess seeds from falling off with the feeding rollers. The flexible nature of the brush roller bristles also prevents the seeds from being crushed during the rotation of the two rollers.

[0059] The soil-dividing plate achieves the effect of leveling the field ridges. The soil scraper has an adjustable angle structure, which can meet the needs of scraping soil at different intensities. The ridge height adjuster can adjust the height of the ridge roller relative to the ground according to the land conditions to meet the needs of different land types.

[0060] Setting up a ridge-ditching mechanism can save space and improve land utilization while meeting the drainage needs between rows on the same ridge.

[0061] By adding a fertilization mechanism above the rotary tillage mechanism and a pesticide spraying mechanism behind the compaction wheel, fertilizer can be applied while the land is being rotary tilled, and pesticides can be sprayed in a timely manner while the seeds are being sown. This saves time in field management and ensures even spraying, saving manpower. Attached Figure Description

The furrow depth should be no less than 10cm, and the width of the furrow top edge should be 15-25cm. The width and depth of the furrow should be such that the soil turned over during furrowing does not cover the soybeans.

[0140] like Figure 16 As shown, when set to one ridge with three groups and six rows, the total width of the ridge top surface is 240cm, and the rest remains unchanged. At this time, the number of the disc soil divider 32, the sowing device 33, the compaction device 34, and the fertilization mechanism 43 of the present invention are all increased and adjusted accordingly.
