A rice precision water direct seeding machine

Abstract

The invention discloses a novel pneumatic rice precision water direct seeding machine, comprising a body, a seed box, a seeding mechanism, a seeding device, a drive system and a walking system, and the seed box, the seeding mechanism, and the seeding device are installed in front of the machine body The part, and the seeding mechanism is set in the seed box, the walking system is installed at the lower part of the fuselage, and the driving system is installed on the fuselage and connected with the seeding mechanism and the walking system through a transmission belt. Without replacing the seed metering device, it can achieve no or less re-suction and the phenomenon that the seeds are perpendicular to the seed-suction hole, and adopt a new type of narrow-edge multi-wheel drive and transportation mode to form uneven and orderly mud surface wheel tracks. It is beneficial to water storage in the paddy field, improves the sowing effect, and achieves the purpose of increasing production and income, and does not need to be equipped with the existing wide-rim wheel for re-soil preparation, and can provide convenience for later field management, spraying, and fertilization.

Description

technical field [0001] The invention belongs to the field of rice sowing, and in particular relates to a precision water direct seeding machine for rice. Background technique [0002] Rice direct seeding is one of the rice planting methods, which saves multi-step procedures such as seedling raising and transplanting, and has the advantages of labor saving, time saving, cost saving, and energy saving. However, a good field drainage and irrigation system, strict field management and weeding techniques are required, and the homogeneity of seedling emergence is greatly affected by the climate. Therefore, under the premise of emphasizing stable and high yield and high multiple cropping index, the development of direct seeding of rice is restricted. my country is the country with the largest rice planting area in the world, and 44% of the area is machine-cultivated rice. The machine collection area is 20%, and the level of mechanized operation is very low. In order to realize t...

Problems solved by technology

[0005] However, due to the fact that the shape of the rice is an ellipsoid, especially the rice grains with a relatively large length-to-diameter ratio, the existing rice direct-seeding seed metering device has problems such as damage to the seeds and a large amount of hole sowing when the mechanical seed metering device is used, and the pneumatic seed suction plate is used. When the seeding method is used, it is easy to cause heavy suction, vertical suction (seeds are perpendicular to the seed suction hole and block the seed suction hole), leakage suction, which is not conducive to seeding or can not be sown. big disadvantage

[0006] And because the driving wheel width of the existing planter is relatively large and the speed of travel is fast, the concentrated compaction surface of the paddy mud surface is relatively large in the process of advancing, and the mud surface is pushed to the wheel side, and the water in the paddy field is impacted. The muddy water waves, the seeds after planting nearby are very likely to be washed out, which seriously affects the effect of sowing and the growth and development process of seeds, and even the yield and quality

[0007] There are existing direct seeding machines that focus on realizing functions other than the sowing function, but do not provide convenient measures and methods for mechanized operations such as fertilization and spraying medicine during the growth of rice, and field management.
