Rice transplanter auxiliary straw returning device

Abstract

The invention discloses a rice transplanter assisted straw turnover device which comprises a bracket, a straw pressing track and a plurality of straw pressing fluted discs, wherein the straw pressing track is arranged on two rollers in a sleeving manner; a plurality of rake teeth are distributed on the straw pressing track; the rollers are fixed on a roller shaft; two ends of the roller shaft are respectively fixed on the bracket through bearings; the straw pressing fluted discs are arranged on a connecting shaft in a sleeving manner; two ends of the connecting shaft are respectively fixed on the bracket; a gear shaft is fixed on the bracket and meshed with the straw pressing fluted discs; and two power mechanisms are fixed on the bracket, wherein one power mechanism is used for driving the straw pressing track to work, pressing straws or weeds on the ground into a shallow underground layer and carding the straws or weeds into a transverse direction, and the other power mechanism is used for driving the straw pressing fluted discs to rotate and further pressing the straws or weeds in the shallow underground layer into a deeper underground position. The device disclosed by the invention is matched with a rice transplanter, so that the straw turnover operation can be completed during rice transplanting. Moreover, soil between two adjacent straw pressing fluted discs is extruded and arched into ridges, rice seedlings can be inserted into the ridges by the rice transplanter, and the condition that rice seedling floating and lodging occur can be avoided.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a rice transplanter auxiliary straw returning device matched with a rice transplanter. Background technique [0002] After the crops are harvested, there are many straws left on the farmland. If there are weeds and duckweeds in the paddy fields, which seriously affect the insertion of the roots of the crops and seedlings into the soil, they must be properly treated. At present, straw is usually disposed of by incineration, which not only seriously pollutes the surrounding environment, but also easily causes fires. Therefore, due to the impact of straw burning on the environment, and the consideration of straw returning to the soil for fertilizing the soil and benefiting the growth of crops, straw returning has become the development trend of agricultural farming. [0003] At present, most of the straw returning machines on the market and in practical applications are used al...

Problems solved by technology

[0003] At present, most of the straw returning machines on the market and in practical applications are used alone. Generally, after the harvest is completed, the straw is crushed and buried in the soil by a rotary tiller. The stalks entered may be pulled out again, affecting sowing or transplanting
