Problems solved by technology

It can complete straw collection, burial, soil covering and other dry land preparation and straw returning operations at the same time in one operation, and can also achieve the effect of deep loosening and fertilization to enhance soil organic matter, effectively realize the joint operation of a single machine, and achieve the tightness of seedlings. The effect of the plowing layer mode with both loose and tight rows between rows solves the problems of intercropping and straw returning to the field

Embodiment

[0038] Example: such as figure 1 As shown, a large ridge double-row straw returning machine of the present invention includes a frame 1, a gearbox 9, a transmission device 8, a straw collecting device 2 arranged sequentially from the working front end to the rear end installed on the frame 1, a medicine Box device 7, burying device 6, soil covering device 5 and suppressing device 4. The straw collection device 2 is composed of two groups of spiral rollers 21 connected symmetrically through a connecting shaft 25, and the connecting shaft 25 is fixed on the frame 1 through a connecting plate 22. Above, each group of spiral rollers 21 is composed of two groups of symmetrically inclined blades, which chop straw and weeds and collect them from both sides to the middle; the rotating shaft cylinder 63 of the buried device 6 is connected to the gearbox 9 The output shaft of the output shaft, the rotating shaft cylinder 63 is connected with the straw collection device 2, the rotary spa...

Embodiment 2

[0051] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the included angle α between the blade of the spiral roller and the horizontal line in this embodiment is 15°; the edge angle of the cutting edge on the blade is 14°. The installation angle β of the rotary spade blade 65 is 81°. The phase angle γ between the soil support plate and the rotary shovel blade 65 is 60°.

Abstract

The invention provides a wide-ridge double-line straw deep burying returning machine and belongs to the technical field of agricultural machinery. The wide-ridge double-line straw deep burying returning machine comprises a rack, a gearbox, a drive device as well as a straw collecting device, a chemical box device, a burying device, a soil covering device and a pressing device which are mounted on the rack from a working front end to a working rear end sequentially, wherein the straw collecting device is formed by symmetrically connecting two groups of spiral rollers through connecting shafts, the connecting shafts are fixed on the rack through connecting plates, each group of spiral rollers are formed by symmetrically and obliquely arranging two groups of blades, and straw and weeds are cutup and collected from two sides to the middle; a rotary shaft tube of the burying device is connected with an output shaft of the gearbox through the drive device and is in drive connection with the straw collecting device, a rotary spade blade of the burying device is arranged in a furrow, and chemical discharge devices of the chemical box device are arranged behind the straw collecting device. The wide-ridge double-line straw deep burying returning machine has the advantages that stubble cleaning, straw collecting, burying, pressing and other work can be completed simultaneously in a working process, deep burying returning of straw is realized, soil fertility is improved, and soil organic matter is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a straw deep burying and returning machine for the double-row planting mode of a large ridge of corn. Background technique [0002] The three provinces in Northeast China are the largest major corn producing areas in the country, with a corn planting area of ​​230 million mu, and the amount of corn stalks that can be collected exceeds 110 million tons each year. However, the total utilization rate of corn stalks in Northeast China is less than 50%, and most of the stalks are discarded or burned, which not only wastes a lot of agricultural resources, but also causes serious environmental pollution. A large number of studies have shown that crop straw is rich in nitrogen, phosphorus, potassium and trace elements, and is one of the important sources of organic fertilizer. Straw returning to the field can effectively increase the content of soil organic ma...
