[0002] There are many kinds of field planters, especially corn planters, in the prior art, with different structures and characteristics.
[0003] After the corn harvester is operated, a large amount of corn stalks are broken and scattered in the field, and the stubble is also retained in the field. In addition, the country now requires that the stalks do not leave the field and prohibits the burning of stalks in the field. Therefore, in order to ensure the spring sowing of the second year, it is necessary to use a hay baler to remove the stalks on the ground, and then carry out stubble removal, plowing, fertilization, and sowing operations.
[0004] The precision seeder is an all-in-one field seeder that is easy to use, has a fast operating speed, and can fertilize, sow, and compact crops. It is particularly suitable for sowing large areas of land such as corn, soybeans, etc., such as the precision seeder disclosed in patent CN202020054359.8.
[0005] However, when the above-mentioned prior art precision seeder is in operation, when there is a large amount of straw left in the field and the soil is humid, the furrowing disc device at the front cannot cut the surface soil layer to make furrows, and the straw piles up under the machine in large quantities, causing the machine to be unable to operate. Therefore, the prior art precision seeder can only be used in the field after the straw and stubble have been removed from the field and the land has been plowed.
[0006] In addition, in order to protect the black soil, the country requires that the surface black soil layer be plowed as little as possible during spring sowing to maintain the black soil. Summary of the invention
[0007] The purpose of the present invention is to provide an integrated field seeder which can be fully applicable to the field when a large amount of straw is retained, and can well perform stubble removal, plowing, fertilizing, sowing, compaction and insurance operations, and ensure the quality of spring plowing and sowing.
[0008] The strip-tillage straw stubble breaking, crushing, fertilizing and sowing integrated machine of the present invention comprises a main beam, a left walking wheel device, a right walking wheel device, a bottom fertilizer box device, a left sowing device assembly, a right sowing device assembly, and a machine main shaft clutch transmission device;
[0009] The left seeding device assembly and the right seeding device assembly are symmetrically and adjustable in spacing on the main beam. The left seeding device assembly / right seeding device assembly comprises a main frame and a ground following connecting rod frame, a depth limiting wheel device, a seeding device, a fertilizing device, and an extruding wheel device respectively connected and installed with the main frame; the ground following connecting rod frame is connected with the main beam; the bottom fertilizer box device is fixedly connected and installed with the main beam through its frame plate; the left walking wheel device and the right walking wheel device are respectively connected and installed with the left and right ends of the main beam through the main beam frame, and a machine main shaft clutch transmission device is provided between the machine main shaft and the walking wheel on the main beam frame, and is characterized in that:
[0010] A rotary tillage assembly is connected and installed with the main beam, and the rotary tillage assembly consists of a gear box transmission device, a rotary tillage shaft, a rotary tillage wheel and a soil collecting cover.
[0011] The box body of the gear box transmission device is fixedly installed and connected to the middle part of the main beam, the input shaft of the gear box transmission device is connected to the power output shaft of the tractor, and the left and right ends of the horizontal output shaft at the lower end of the gear box transmission device are respectively connected to the left rotary tillage shaft and the right rotary tillage shaft; the left rotary tillage wheel and the right rotary tillage wheel are respectively fixedly installed on the left rotary tillage shaft and the right rotary tillage shaft, and rotary tillage blades are circumferentially fixedly installed on the left rotary tillage wheel / the right rotary tillage wheel; the left soil collecting cover and the right soil collecting cover are respectively arranged corresponding to the connection with the main beam; the left soil collecting cover and the right soil collecting cover are respectively fixedly connected with soil splitting knives, and a fertilizer discharge pipe connected with the discharge pipe of the bottom fertilizer box device is fixedly installed close to the rear side of the soil splitting knife.
[0012] The present invention is based on an existing precision seeder including a main beam, a left running wheel device, a right running wheel device, a base fertilizer box device, a left sowing device assembly, a right sowing device assembly, and a machine main shaft clutch transmission device.
