Spiral mill type ditching straw deep-burying chopper

Abstract

The invention discloses a spiral mill type ditching straw deep-burying chopper, and belongs to the technical field of an agricultural machine. The spiral mill type ditching straw deep-burying chopper comprises a frame, a front drive box, a drive device, a back drive box, and a stubble cleaning device, a conveying device, a round disk ditching device, a spiral mill ditching device, a blanker and an earthing device which are orderly installed on the frame from the front end to the back end; a stubble cleaning shaft of the stubble cleaning device is connected to a power output shaft of the front drive box, the conveying device is installed slantly, and both ends are respectively connected with the stubble cleaning device and the blanker; the spiral mill ditching device is installed beneath the back drive box; the round disk ditching device is located in front of the spiral mill type ditching device; the round disk ditching device cuts off soil, and reduces resistance; the spiral mill type ditching device is used for ditching work; the blanker is located between the spiral mill type ditching device and the earthing device. The spiral mill type ditching straw deep-burying chopper can complete stubble cleaning, straw collection, burying, repression, drought soil preparation, and straw returning works, and reach the effect of deeply burying straw, returning field, and enhancing the soil organic matter.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a helical milling cutter type ditching straw deep burial returning machine. Background technique [0002] Corn stalks have the characteristics of large quantity and thick stalks, and the burning of surplus corn stalks is serious. The harm caused by straw burning is the first, which has seriously affected civil aviation, transportation and other departments; second, the burning of straw has brought a lot of smoke, causing air pollution and environmental safety problems. The smoke contains CO, CO2, nitrogen oxides, photochemical Oxidants, etc., are harmful to the human body; thirdly, the burning of straw can emit a large amount of CO2, and a large amount of C and N are lost, resulting in a waste of resources. [0003] One technology to prevent straw burning is to return straw directly to the field. Straw returning to the field directly can be divided into mulching ...

AI Technical Summary

Problems solved by technology

At present, the straw is crushed and covered to return to the field, and the stubble is crushed and returned to the field with a stubble cutter, and the straw and soil are mixed with a rotary tiller, and the straw cannot be buried deeply.

This causes the straw to lift up the soil, and after the planter sows, the soil loses moisture seriously, and the seeds cannot germinate normally, which affects the corn yield.
