Soil covering device for wheat seeding machine with high budding rate

Abstract

The invention discloses a soil covering device for a wheat seeding machine with a high budding rate. The soil covering device comprises a soil digging mechanism and is characterized in that the soil digging mechanism is connected with a collecting mechanism in a matched mode; the collecting mechanism is connected with a stirring box through a pipeline; the stirring box is located above the collecting mechanism; two sets of material storage mechanisms are arranged in the stirring box; a soil covering mechanism is further arranged below the stirring box; the soil digging mechanism comprises an outer roller; a pump pressure cavity is formed in the outer roller; a plurality of internal combustion cavities are formed outside the pump pressure cavity in a surrounding mode; digging teeth are arranged on the outer portion of the outer roller in a surrounding mode; the other sides of the internal combustion cavities are connected with the digging teeth; a cam is arranged in the pump pressure cavity; a telescopic rod is arranged in each internal combustion cavity, and a piston nozzle is arranged at one end of each telescopic rod; the piston nozzles and the cam are of a matched structure; and a grinding pad is arranged between the digging teeth and the internal combustion cavities. The soil covering device has the characteristics of good digging effect and high wheat germination rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a soil covering device for a wheat planter with a high germination rate. Background technique [0002] In wheat planting, common underground pests include grubs, etc. Underground pests are very harmful. They can directly eat wheat seeds. There are a large number of earthworms in the soil, and the pulp of earthworms is viscous; usually fertile soil has more water content and softer texture, while harder soil is generally suddenly poor in nutrition due to lack of water. [0003] Since the wheat seeder needs to turn up the soil and then sow the wheat seeds when it is working, it will cause the sown seeds to be partially exposed to the air, so it needs to be manually covered with soil, but there is no such thing on the currently used wheat seeder. Soil-covering devices are installed, so the germination rate of wheat will be greatly reduced, resulting in a reduction in...
