Precision seeder capable of realizing synchronous transmission of conveying and rotary drum

Abstract

The invention provides a precision seeder capable of realizing the synchronous transmission of conveying and a rotary drum. The precision seeder comprises a rack, wherein a hole pressing part, a seed clearing part, a seed storage vibration part and a seeding part which are connected to one another through a transmission mechanism are arranged on the rack, a seedling growing tray is arranged on the transmission mechanism, the hole pressing part comprises a hole pressing shaft arranged on the rack, hole pressing wheels are arranged on the hole pressing shaft, hole pressing lugs on the hole pressing wheels are in contact with the seedling growing tray, the seed clearing part comprises a seed clearing and air blowing pipe arranged on the rack, a seed clearing and air blowing nozzle is arranged on the seed clearing and air blowing pipe, the seed storage vibration part comprises a seed storage groove and a seeding vibrator which is arranged on the rack, the seed storage groove is formed in the rack, the seeding part comprises a seeding shaft arranged on the rack, the seeding rotary drum is arranged on the seeding shaft, a seeding hole is formed in the seeding rotary drum, the transmission mechanism comprises a conveyer belt arranged on the rack, and the conveyer belt and the seeding shaft are driven by the synchronous transmission mechanism. The precision seeder is small in size, high in seeding precision, and convenient to install and debug, saves the cost, realizes the synchronous transmission of conveying and seeding and has the good conveying and seeding coordination property.

Description

technical field [0001] The invention relates to a seed precision sowing machine with synchronous transmission and roller transmission, which belongs to the field of agricultural machinery equipment. Background technique [0002] At present, a large number of mechanized seeding has been used for sowing seeds (such as tobacco, fruit and vegetable seeds). Each part is independently installed on its own frame and connected by a conveying mechanism. When working, the conveying mechanism and each part are driven by their own power. The disadvantages are: 1. The conveying mechanism is long and the whole machine is large. It takes up a lot of space and costs high; 2. The transmission mechanism of each department and the sowing setting have different powers, which need to be coordinated through the control mechanism. This structure is complicated and the cost is high, but in actual use, there is poor sowing accuracy; 3. Installation, Debugging trouble. Contents of the invention ...
