Seeder

Abstract

The invention discloses a seeder which comprises a frame, a furrowing blade, a press wheel, a driving wheel and a suspended pin. The seeder is characterized in that one end of a seeding axis is provided with a transfer gear which consists of a short axis connected with the seeding axis by a ratchet wheel device, and cams and contact switches on the short axis, wherein the contact switches are connected with a battery wire which is arranged on the frame, an electromagnetic valve wire arranged in seeding passages and the cams. The short axis is provided with two cams which are arranged in dislocation. Two contact switches are arranged, one is connected with electromagnetic valves in seeding passages 1 and 3, and the other is connected with electromagnetic valves in seeding passages 2 and 4. The seeder is added with the transfer gear on the basis of the structure of a traditional seeder, thus changing the present situation that originally, all seeding passages seed simultaneously, realizing rational close planting, reducing the production cost and improving the field efficiency of the seeder.

Description

technical field [0001] The sowing machine of the invention belongs to the field of agricultural machinery, and in particular relates to a sowing machine. Background technique [0002] At present, the planter is mainly composed of a frame, a ditching shovel, a pressing wheel, a driving wheel, a seed box, an upper suspension pin, a lower suspension pin, and a seed pipe. The upper suspension pin and the lower suspension pin are connected to the front end of the frame, and the The ditch shovel and the pressing wheel are respectively fixed under the frame on the front and rear sides of the seed box; the output port of the seed box is connected to the seeding channel connected with the ditching shovel through the seed tube, and the driving wheel is installed on the back of the frame , is connected to the seeding shaft through a chain. The disadvantage of this type of planter in the working process is that the seeds in all the seeding channels are broadcast at the same time, so tha...
