Description
Technical Field
The utility model relates to a soil covering device.
Background
The first industry in China is agriculture, one of the most important crops is corn, and the corn is one of the crops with the highest yield in the north of China. The corn planting adopts advanced machinery, so that not only can labor be saved, but also the corn yield can be improved to a great extent.
The corn seeding is to utilize a corn seeder to sow seeds on a proper soil layer, and the seeds are kept consistent in distance and depth as far as possible during seeding and are positioned in the same row. Before corn sowing, a furrow opener is used for opening a seed furrow, then a seed discharging pipe discharges seeds into the seed furrow, finally a soil covering disc is used for covering soil, the soil covering disc covers the soil to extrude and combine the soil on two sides of the seed furrow towards the middle, and the corn seeds are easy to be impacted by the soil transmitted by the soil covering disc to deviate from the original position when the soil covering disc covers the soil, so that the sowing distance and the sowing depth are deviated.
SUMMERY OF THE UTILITY MODEL
The utility model provides a soil covering device of a corn seeder, which solves the problem that the deviation of seeding distance and seeding depth is easily caused by the back earthing process of the prior corn seeder.
The utility model of the corn seeder covering device is composed of two main earthing disks, a rear bracket, two auxiliary earthing disks and a front bracket; the two main soil covering disks are arranged on the rear bracket, the two auxiliary soil covering disks are arranged on the front bracket, the front bracket is arranged in front of the rear bracket, and the front bracket and the rear bracket are connected through a connecting rod; the diameter of the auxiliary soil covering disk is 40% -50% of that of the main soil covering disk, and the lower edge of the auxiliary soil covering disk is located at the position 50% -60% of the vertical height of the main soil covering disk.
The utility model discloses principle and beneficial effect do: the utility model discloses corn drill earthing device is provided with two sets of earthing disks, wherein the less and higher vice earthing disk in position of size is located the front portion, the great and lower main earthing disk in position of size is located the rear portion, when carrying out the earthing after the seeding, the first soil of higher department in kind ditch both sides of scraping of vice earthing disk, then the main earthing disk that is located the rear portion revolves the surplus soil and covers to the seed on, because vice earthing disk position is high and the diameter is little, therefore vice earthing has been spiraled and has been played a small amount of soil and cover the seed, strike little to the seed, can not change the seed position, because the protection of earthing in earlier stage when carrying out a large amount of earthing again, the seed still can not change the position, seeding interval and depth of planting have been guaranteed, the production of deviation has been avoided, the seeding precision has been improved.
Drawings
Fig. 1 is a schematic structural view of the coverer of the corn drill in example 1, wherein a is an inclination angle of the auxiliary casing tray 3, and b is an inclination angle of the main casing tray 1.
Detailed Description
The technical scheme of the utility model is not limited to the specific implementation modes listed below, and also comprises any reasonable combination between the specific implementation modes.
The first embodiment is as follows: the corn planter covering device of the embodiment is composed of two main soil covering disks 1, a rear bracket 2, two auxiliary soil covering disks 3 and a front bracket 4; the two main soil covering disks 1 are arranged on the rear bracket 2, the two auxiliary soil covering disks 3 are arranged on the front bracket 4, the front bracket 4 is arranged in front of the rear bracket 2, and the front bracket 4 is connected with the rear bracket 2 through a connecting rod 5; the diameter of the auxiliary soil covering disk 3 is 40% -50% of that of the main soil covering disk 1, and the lower edge of the auxiliary soil covering disk 3 is located at the position 50% -60% of the vertical height of the main soil covering disk 1.
This embodiment corn drill covering device is provided with two sets of earthing pan 1, wherein the less and higher vice earthing pan 3 in position of size is located the front portion, the less and lower main earthing pan 1 in position of size is located the rear portion, when carrying out the earthing after the seeding, vice earthing pan 3 is at first scraped the soil of getting the higher department in kind ditch both sides, then main earthing pan 1 that is located the rear portion is spun the surplus soil and is covered to the seed on, because vice earthing pan 3 position is high and the diameter is little, therefore vice earthing pan 3 has been spun a small amount of soil and is covered the seed, strike little to the seed, can not change the seed position, because the protection of earthing in earlier stage when carrying out a large amount of earthing again, the seed still can not change the position, seeding interval and seeding depth have been guaranteed, the production of deviation has been avoided, the seeding precision has been improved.
The second embodiment is as follows: the first difference between the present embodiment and the specific embodiment is: the upper edges of the two main soil covering trays 1 are respectively inclined to two sides, and the inclination angle is 60 degrees.
The third concrete implementation mode: the present embodiment differs from the first or second embodiment in that: the upper edges of the two auxiliary soil covering trays 3 are respectively inclined to two sides, and the inclination angle is 30 degrees.
