Manual sowing machine for improving sowing quality

Abstract

The invention provides a manual sowing machine for improving sowing quality, and belongs to the technical field of sowing machines. The manual sowing machine comprises a seed metering device and a cam-shaped track, wherein a movable groove is uniformly formed in the seed metering device, an supplementing piece is arranged in the movable groove, a detecting piece is inserted in the supplementing piece, a shifting column is fixedly connected to the detecting piece, a chain wheel is arranged in the cam-shaped track, and a driving rod is arranged on the chain wheel. According to the manual sowingmachine, the driving rod on the cam-shaped track is used for driving the supplementing piece through the driving rod on the detecting piece, seeds fall into the detecting piece under action of gravity, the detecting piece drives the seeds to fall into a seed metering opening, a situation that seeds are missed due to missing of a seed metering device during sowing is effectively prevented, thus themanual sowing machine ensures uniformity of seeding, increases yield of crops, reduces unnecessary replanting, increases uniformity of crop growth, reduces difficulty of harvesting, further can quickly and efficiently supplement for the missing sowing condition, reduce mechanical loss and prolong service life.

Description

technical field [0001] The invention relates to the technical field of seeders, in particular to a manual seeder for improving seeding quality. Background technique [0002] With the continuous development of science and technology, agricultural machinery tends to be more and more automated, but for some special geographical environments, agricultural machinery with a high degree of automation cannot be applied, and there are still some fragmented land with a relatively small area that uses agricultural machinery with a high degree of automation. Machinery will make the utilization rate of resources too low, which does not meet the development requirements of energy conservation, environmental protection and full utilization of resources in the current society. [0003] Under the above-mentioned prospects, the manual seeder was born under the demand of agricultural development. By manually pushing the seeding, it can realize the seeding of small fragmented land and some non-...

AI Technical Summary

Problems solved by technology

[0004] There are many factors that affect the quality of sowing, one of the more important ones is missing sowing, which is mainly due to the failure of the seeds to be brought into the groove when the seed metering device rotates, resulting in no Seeds are discharged, resulting in missed sowing. Missed sowing directly affects the uniformity of sowing, thereby affecting the yield of crops, or replanting is required. Replanting will not only increase the amount of extra labor, but also affect the uniformity of the growth state of crops. Subsequent harvesting brings certain difficulties
