Corn straw returning fertilizer application device

Abstract

The invention discloses a corn straw returning fertilizer application device which comprises a frame. A transmitting mechanism is arranged at the left end of the frame, a straw cutting and conveying device is connected at the left end of the transmitting mechanism, an output guide pipe is connected at the right end of the transmitting mechanism, an output port of the output guide pipe is connected with an inlet of a secondary chopping device formed in the frame, a corn straw root pickup wheel is arranged below the frame, a rotating shaft is mounted in the corn straw root pickup wheel, harrow teeth are arranged on the rotating shaft, and a corn rhizome crushing device is connected on the right side of the corn straw root pickup wheel. According to the corn straw returning fertilizer application device, the secondary chopping device is additionally arranged, a horizontal spiral cutting blade and a spread spiral cutting blade are used for cutting and crushing, corn rhizomes are excavated through a plough share, picked up by the corn straw root pickup wheel and crushed, whole resources are saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery devices, in particular to a fertilization device for returning corn stalks to the field. Background technique [0002] Straw returning is a method of returning corn stalks to the field to apply straws (corn stalks, sorghum stalks, etc.) that are not suitable for direct feed into the soil directly or piled up and decomposed. It can improve soil properties, accelerate soil ripening, and improve soil fertility. When directly plowing the straw, some nitrogen fertilizer should be applied to promote the straw to decompose in the soil and avoid competition between decomposing bacteria and crops for nitrogen. [0003] Straw returning to the field has the advantages of promoting the increase of soil organic matter and nitrogen, phosphorus, potassium and other contents; improving the storage capacity of soil moisture; improving plant properties and crop yield; improving soil properties and i...

Problems solved by technology

[0004] However, the stalks crushed by the existing device are relatively large, of different lengths, and rot slowly, and cannot be absorbed and utilized by the soil quickly. At the same time, the existing crushing device does not crush the rhizome of corn, which affects the crops to a certain extent. production; returning the diseased straw to the field after smashing it will lead to the spread of the disease, and harmful substances such as insect eggs attached to the straw will also cause harm to the sown crops, causing environmental pollution and property loss
