Rotary tillage combined seed and fertilizer drill

Abstract

The invention discloses a rotary tillage combined seed and fertilizer drill which comprises a rack. A power transmission mechanism is arranged on the rack; a first rotary cultivator is further arranged on the rack; a mud and grass conveyor belt is arranged above the first rotary cultivator; a suppressing roller is arranged behind the first rotary cultivator, and roller burs are arranged at the periphery of the suppressing roller; a drill barrow foot is arranged behind the suppressing roller, a part of drill barrow foot is parallel to the arc shape of the peripheral face of the suppressing roller, an arch opener is arranged at the lower end of the drill barrow foot, the spine of the front end of the arc opener is in an arc shape, the arc portion of the arc opener is tangent with the arc portion of the drill barrow foot, and the drill barrow foot is located at the dead astern of the motion track of the corresponding roller burrs; a plug removal rotary knife roller is arranged behind thedrill barrow foot, a plug removal rotary knife is arranged at the peripheral face of the plug removal rotary knife roller, the plug removal rotary knife is located at the side edge of the drill barrowfoot when rotated to the front part, and the first rotary cultivator, the mud and grass conveyor belt, the suppressing roller and the plug removal rotary knife roller are the same in rotating direction. The rotary tillage combined seed and fertilizer drill has the advantages that mud and grass are removed easily, the stress of the drill barrow foot is small, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a seeder for rotary tillage and fertilization. Background technique [0002] The rotary tillage fertilization and seeding machine in the prior art does not have a good effect of soil preparation and crushing. Generally, farmers require two rounds, first rotary tillage once and then rotary tillage, fertilization and seeding. The disadvantage is that it will cause soil moisture loss and is prone to defects. If the seedlings are broken, if it is rainy and the seeds cannot be sown, the farming time will be delayed; when the soil moisture content in the field is high and the crop straws are returned to the field in full, the bottom of the protective plate above the rotary tiller shaft is full of mud and grass, which is prone to blockage Dead, as the Chinese utility model patent that application number is CN200820231042.6 discloses a kind of multifunctional rotary tillage seeder, ...
