Maize and soybean interplanting machine

Abstract

The corn and soybean interplanting machine comprises a connecting frame, rolling bottom wheels are installed at the bottom of the connecting frame, and a digging mechanism, a smoothing mechanism, a slotting mechanism, a sowing mechanism and a soil covering mechanism are sequentially installed in the connecting frame from left to right. According to the corn and soybean interplanting machine, a driving motor at the bottom of a protective shell drives a connecting sleeve to rotate, and the connecting sleeve is fixedly connected with digging shovel pieces, so that the two digging shovel pieces arranged front and back are driven to dig soil in a soybean planting area, and the dug soil is accumulated in a corn planting area under the action of side baffles; a height difference is formed between the corn planting area and the soybean planting area, after soil excavation, a bearing plate and a forming pressing plate on the rear side of the soil excavation mechanism renovate the soil in the two planting areas, and meanwhile, the soil is rapidly bonded under the action of a vibration hammering head to form two step-shaped planting areas; therefore, the corns and the soybeans can be conveniently planted at different heights.

Description

technical field [0001] The invention relates to the technical field of corn and soybean interplanting, in particular to a corn and soybean interplanting machine. Background technique [0002] As we all know, intercropping refers to the planting method of sowing or transplanting the next season crops between the rows of the previous season crops in the late growth period, also known as intercropping and string planting. Compared with single cropping, it can not only make full use of the space in stages, but more importantly, it can prolong the growing season of the latter crops and increase the multiple cropping index. The interplanting of corn and soybeans can increase the interception and absorption of sunlight and reduce the loss of light energy. At the same time, the intercropping of two crops can also produce complementary effects. For example, tall crops in wide and narrow row intercropping or strip intercropping have certain side row advantages, and intercropping betwe...

Problems solved by technology

[0003] Corn and soybean interplanting mostly use the form of 3 rows of corn and 4 rows of soybeans, but during the growth of corn and soybeans, the roots of soybeans can only extend in the shallow soil of 5-20CM, while the roots of corn can extend deeper than 1.5 meters (including radicle, nodal root and supporting root), among which the nodal root (at 0.5-1M) plays a major role in absorbing nutrients. If soybean and corn are planted at the same height, then the soybean root system is relatively shallow, and the soybean root system is not compatible with The nodal roots of corn are at the same depth, so that the corn absorbs less nitrogen and fixes the nitrogen-fixing bacteria on the surface of soybeans, resulting in no obvious advantages of interplanting. At the same time, in hot summer, corn and corn are planted at the same depth, and the hot sun Although blocked by the corn leaves, the corn in the middle receives less sunlight, and the sunlight will always shine on some soybean leaves through the gaps between the corn leaves (such as Figure 7 shown), resulting in uneven growth of both soybeans and corn, so that corn soybeans (such as Figure 8 As shown) stepped planting, in order to solve the above problems, in order to plant corn and soybeans in steps, we propose a corn soybean interplanting machine
