Description

Wheat wide furrow sowing columbine

technical field

The utility model relates to an agricultural seeding machine tool, in particular to a wide-width ditch sowing columbine.

Background technique

In recent years, the mechanized straw returning technology has been widely promoted in wheat-corn double-cropping areas. In the current situation of serious shortage of organic fertilizer, straw returning to the field year by year is beneficial to improving soil structure, supplementing soil organic matter, increasing Land production potential is of great significance; however, it also brings many problems, especially the corn stalks seriously affect the quality of wheat land preparation, which in turn affects the quality of sowing. Dragging and tucking can cause lack of seedlings and broken ridges or crowding of seedlings (pimple seedlings). In terms of production, wheat farmers adopt the traditional drill sowing method, and generally blindly increase the amount of sowing due to concerns about insufficient groups, which not only increases the cost of seed input, but also further aggravates the competition among individuals due to overcrowding of seedlings, resulting in weak seedlings, The phenomenon of small seedlings, weak tillers, and small tillers will lead to small spikes and fewer grains, and a decrease in thousand-grain weight, which will affect yield.

In order to solve the above problems, a lot of research work has been carried out, and technologies such as wheat wide-width sowing, wheat wide-width + broadcast combined sowing, and double-row hard stubble furrow sowing of wheat have been invented, and the traditional drill sowing technology has been improved. These technologies have their own advantages and disadvantages. Wheat wide-width sowing and wheat wide-width + sowing combined sowing have outstanding performance in improving the dispersion and uniformity of wheat seeds, but they still cannot fundamentally solve the problems caused by soil warping. And cause problems such as hanging roots and dead seedlings; single sowing technology can also improve the dispersion and uniformity of wheat seeds, but it is a waste of seeds, and the field is poorly ventilated; wheat double row hard stubble furrow sowing technology is a new technology that can After mechanical harvesting of corn, wheat is planted in hard stubble, and the double-row moisture detection furrow sowing can improve the emergence effect, save the amount of seeds, improve the uniformity of sowing, and play the role of covering by corn stalks, etc., but the sowing uniformity is relatively poor, and The effect of the application in the same year is acceptable, and the application in successive years will not allow the soil to be deeply loosened and deep-spun, and the soil permeability will become poor.

Contents of the invention

In order to solve the problems of deficient soil, poor ventilation effect and poor soil permeability existing in the existing sowing equipment, the utility model provides a wide-width pressing ditch sowing columbine.

The utility model is realized by adopting the following technical scheme: the wheat wide-width pressure ditch sowing columbine includes a frame, a fertilizer hopper and a seed hopper are arranged above the frame, a rotary tillage mechanism is arranged under the frame, and the machine on the front and top of the rotary tillage mechanism The frame is fixed with an inclined fertilizer ejection plate, and the fertilizer hopper is connected with a fertilizer pipe whose outlet is located above the inclined surface of the fertilizer ejection plate. The frame behind the rotary tillage mechanism is equipped with a number of straw diversion openers distributed left and right. The frame behind the diversion opener is equipped with a compacting ditching wheel, and the frame behind the compacting ditching wheel is equipped with a wide-width seed meter connected to the seed hopper, and the machine behind the wide-width seed meter The frames are all provided with seed compacting wheels, and the central axis of the seed compacting wheels is connected with the intermediate shafts of the fertilizer hopper and the seed hopper through transmission chains.

During operation, the tractor output power is used to drive the rotary tillage mechanism for rotary tillage. Under the action of the fertilizer ejection plate, the fertilizer exported from the fertilizer hopper is evenly spread on the soil through the fertilizer ejection plate, and evenly rotated on the soil by the rotary tillage mechanism. However, the straw is diverted and ditched by the straw diversion ditch opener, followed by the compaction ditch wheel to compact the soil in the ditch, and then the wide seed metering device spreads the wheat seeds evenly on the compacted surface. Finally, through the seed compaction wheel and the soil covering device, the seeds are in close contact with the compacted soil and covered with an appropriate amount of virtual soil to complete the sowing, which overcomes the problems of soil warping, poor ventilation and soil ventilation in existing planting machines. The problem of poor permeability.

The structure design of the utility model is reasonable and reliable. The wheat seeds are sown on the soil under the straw through the diversion of the straw, which overcomes the influence of corn returning the straw to the wheat sowing quality, does not need to increase the sowing rate, saves costs, and through soil compaction and The seeds are compacted to avoid the influence of the soil warping on the quality of the seeds after deep loosening or rotary tillage, and there will be no phenomenon of hanging roots and dead seedlings. At the same time, the fertilizer is evenly ejected in the field through the fertilizer ejection plate, and evenly dispersed by the rotary tillage mechanism. Into the plow layer soil, reduce the risk of fertilizer burning seeds, and facilitate the absorption and utilization of fertilizer by the root system.
