Duplex intertillage weeding machine

Abstract

The invention discloses a duplex intertillage weeding machine which can be used for completing the processes of performing side deep fertilization, performing soil loosening and weeding among seedlings, performing ridging, performing earth up, performing deep scarification and the like in the intertillage process. The duplex intertillage weeding machine comprises a soil covering shovel, a soil covering shovel bracket, a profiling single body, a tensioning spring and a four-bar linkage, a profiling mechanism suspension bracket, a fertilizer box, a fertilizer discharging wheel, a fertilizer boxsupport, a machine frame, a middle shaft, ground wheels, a ground wheel support, a fertilizer discharging furrow opener, a deep-scarification shovel base, a deep-scarification shovel handle, a weedingsingle body gear box, a comb tooth roller, a lifting rod, a profiling wheel, comb teeth, an adjusting screw rod, and a profiling wheel bracket, wherein during operation, the ground wheels transmit power to a fertilizer discharging shaft, and drives the fertilizer discharging shaft to apply fertilizer; the fertilizer is conveyed to the side deep fertilizing furrow opener through a fertilizer spreading pipe for realizing the ridging side deep fertilizing; the weeding device drives the vertical rotating spiral comb tooth type weeding device to work; and the deep scarification operation is completed by the shovels; and the soil covering device is used for covering soil. The duplex intertillage weeding machine has the characteristics of novel structure, safety and reliability, low cost, automatic operation and the like.

Description

Technical field [0001] The invention relates to a compound intertillage and weeding machine capable of completing the operation process of corn and soybean in the intertillage process, such as side-deep fertilization, weeding between seedlings, ridging, soil cultivation and subsoiling. Background technique [0002] During the growth period of crops, removing weeds between the rows (outside the seedling belt or on the side of the ridge) and between the seedlings (the seedling belt) is an indispensable and effective measure to ensure high and stable yields. Mechanical weeding does not pollute the environment, and has the advantages of loosening the soil, increasing the ground temperature, storing water and moisture, and benefiting the growth of crops and seedlings. Therefore, mechanical weeding has been widely used in global dryland agricultural production. But weeding at home and abroad is mainly based on chemical weeding. [0003] The method of chemical weeding has many ha...
