Technical Field

The invention relates to the technical field of agricultural instruments, in particular to an integrated corn direct seeding machine for synchronous seeding and soil conditioner and fertilizer application.

Background

As is well known, modern agricultural machines such as large-scale sowing machines and harvesting machines have been popular for many years, and small-scale seed sowing machines tend to develop in a multifunctional and compact direction, and when corn sowing is performed, a considerable part of farmers also work in the field by means of agricultural machines with low work efficiency, and the efficiency is low.

The Chinese patent with the patent publication number of CN202095270U discloses a full-film covered double-furrow corn hole direct seeding machine, belongs to the technical field of seeding machines, and particularly relates to a full-film covered double-furrow corn precise hole direct seeding machine. The power device and the speed changing device of the machine are fixed on a traction frame, and the frame is connected with the traction frame through a hanging plate. The speed changing device drives the walking land wheel to drive the hole direct seeding machine to move forwards. The ejector rod is fixed with the ejector rod frame, the seed guide tube is arranged on the ejector rod frame, the ejector rod is connected with the cam through the reset spring, the cam pushes the ejector rod, and the advancing speed is compensated for the seed guide tube at a speed equal to and opposite to the advancing direction of the whole machine, so that the horizontal speed of the cavitation duckbilled is kept to be zero when the cavitation duckbilled enters and exits the soil. The rotation speed between the middle transmission shaft and the cam transmission shaft is changed, and the planting distance is adjusted. The length of the seed guide tube is changed to adjust the sowing depth. The seed metering device arranged on the crank seed metering shaft is controlled to realize the precision of seed metering. The machine not only can adapt to a full-film-covered double-furrow sowing and planting mode, but also is suitable for other agricultural planting requirements of plastic film coverage.

At present, farmland in China has serious metal pollution, and the safe production of grains is endangered. The in-situ passivation of heavy metals is one of key technologies for realizing the safe production of cadmium-polluted farmlands. The in-situ passivation technology of the heavy metal in the soil is characterized in that an exogenous restoration agent is added to perform a series of reactions such as adsorption, sinking, ion exchange, oxidation reduction and the like on the heavy metal, so that the occurrence form of the heavy metal in the soil is changed, the mobility and the bioavailability of the heavy metal in the soil are reduced, and the poison of the heavy metal to the living beings and the accumulation of the heavy metal in agricultural products are reduced. The research of the heavy metal in-situ soil conditioner technology mainly focuses on the development and restoration effect evaluation of a stable material suitable for the passivation of heavy metals in polluted soil, and the research of the application of a novel technology of the heavy metal soil conditioner is ignored. The current heavy metal soil conditioner application method mainly comprises surface layer broadcast application, and has the problems of more input materials, high application cost, secondary pollution risk, large influence on physical and chemical properties and biological properties of soil and the like in actual production and application. The application of the patent in the farmland safety production with heavy metal pollution has the following obvious defects:

first, existing machines do not have the functions of sowing, soil conditioning and fertilizer synchronous application, and the aim of safe production of heavy metal polluted cultivated land corns cannot be fulfilled by means of current equipment.

Secondly, the existing corn planter needs to manually broadcast the soil conditioner on the soil before sowing corn, and then stir the soil, thereby reducing the bioavailability of heavy metals in the soil and improving the quality of the soil. The method has low working efficiency and labor consumption, and the broadcasting quantity of the soil conditioner cannot be accurately controlled, so that the soil conditioner is wasted.

Thirdly, the mixing of the soil and the soil conditioner belongs to a large-batch mixing mode, so that uneven coverage of the soil conditioner in the soil can occur, local non-improvement of the soil can occur, and careless mistakes can occur.
