Description

Technical Field

[0001] This invention relates to the field of sowing technology, and in particular to a multi-unit sowing machine for increasing the yield of soybeans planted in dense rows. Background Technology

[0002] With global population growth and increasing constraints on arable land resources, the demand for large-scale, high-efficiency soybean cultivation is becoming increasingly urgent, as soybeans are an important grain and oil crop and a source of protein. The wide-ridge dense planting technique, by expanding row spacing and optimizing plant spacing, significantly improves field ventilation and light penetration, lodging resistance, and yield per unit area, and has become one of the core methods for increasing agricultural production in modern agriculture.

[0003] Traditional seeders are typically configured with 2-3 seeders, limiting the number of seedling rows. For example, patent CN202010524909.X describes a seeding device with a "two-double-one-single" seedling layout, which achieves wide and narrow row planting by adding a middle single row of seeders, improving ventilation and light transmission. However, such designs still cannot meet the needs of ultra-high density planting.

[0004] To address these issues, a multi-unit planter for dense soybean planting on wide ridges is proposed to improve yield per unit area. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-unit planter for soybean dense planting in wide ridges to improve yield per unit area, thereby solving the problems existing in the prior art and achieving the effect of improving yield per unit area in dense planting in wide ridges.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a multi-unit planter for increasing the yield of soybeans through dense ridge planting, comprising:

A depth limiting wheel is installed on the depth limiting wheel support arm.

[0010] This invention discloses the following technical effects: In this device, the traction device is used to connect with a tractor, which pulls the device to move. The fertilizer box assembly contains fertilizer, and the fertilizer furrow opener assembly is used to open furrows. Fertilizer can be spread simultaneously with sowing, and the fertilizer is spread into the opened furrows. The gearbox assembly is used to transmit power. The tractor transmits power to the gearbox assembly, which then transmits it to the first and second sowing sections to complete the sowing operation. The front and rear sowing bodies allow for staggered sowing between adjacent rows. The three sets of sowing units can achieve a large ridge effect. Each sowing unit has two front sowing bodies and two rear sowing bodies, enabling dense planting of four rows of soybeans. The compaction frame assembly is used to compact the soil covering after sowing. The purpose of the long and short compaction connecting frames is to stagger the sowing of adjacent front and rear sowing bodies. This invention, through the large-interval arrangement of multiple sowing units and the two front and two rear sowing bodies in each sowing unit, achieves the effect of dense planting of soybeans in large ridges, meeting the sowing requirements.
