Automatic seeder with adjustable seeding distance

Abstract

The invention discloses an automatic seeder with an adjustable seeding distance, and relates to the technical field of granular seed seeder equipment. The automatic seeder comprises a base frame, thetop side of the base frame is fixedly provided with a hopper and three conveying pipes through a support frame, and the three conveying pipes are all provided with discharging mechanisms; and two rollers and three cams are rotatably mounted at the bottom side of the base frame through a central rotating shaft, and a plurality of arc-shaped spokes are uniformly and rotatably mounted at one side ofeach of the two rollers through a plurality of fixing shafts. The automatic seeder is reasonable in structure and easy to operate, the three conveying pipes are arranged for seeding at the same time,the discharging mechanisms move to release seeds once by rotating the cams by a circle, the seeding distance is the outer circumferential length of the rollers, and the outer circumferential length ofthe rollers is changed by adjusting the distance between one end of each of the multiple arc-shaped spoke and the central rotating shaft, so that the longitudinal seeding distance is adjusted, and the distance between the three conveying pipes is adjusted through a distance adjusting cross rod, namely, the seeding line distance is adjusted.

Description

technical field [0001] The invention relates to the technical field of granular seed seeder equipment, in particular to an automatic seeder with adjustable sowing distance. Background technique [0002] One of the cultivation measures for sowing crops is to sow the sowing materials into the soil layer at a certain depth in a certain amount and in a timely manner. In order to improve the quality of sowing, in addition to fine soil preparation before sowing, it is also necessary to do a good job of seed treatment, as well as labor and animal power. According to the crop type, variety characteristics, planting system, cultivation method and its requirements for environmental conditions, select the appropriate sowing date, sowing amount and sowing method, and sow the seeds to a certain depth by hand or with machines. For comprehensive agricultural operations in the soil layer, the appropriateness of sowing directly affects the growth and yield of crops. Common methods include so...

Problems solved by technology

[0003] In the prior art, when farmers sow in a small area or in areas that cannot be reached by large-scale machinery, they usually use manual sowing. Manual sowing can only sow one seed hole at a time, and it is necessary to bend over to reduce the falling height of the seeds. Accurately falling the seeds into the planting hole is labor-intensive and inefficient. In addition, the sowing distance depends on experience and consciousness. For those who are inexperienced, the operation is difficult. Adjust the automatic seeder to meet people's needs
