Compound laying-type double-weeding-cutter weeder

Abstract

A double-grass lawn mower capable of completing weeding and other processes in the intertillage process. The device includes power, a frame, a transmission device, a grass knife shaft, a cutter head, a grass knife, a supporting wheel, and a belt cover. The mowing part adopts rotary double grass knives; the grass knives are placed in front of the walk-behind tractor, which is beneficial to expand the operator's field of vision, with good passing performance and flexible turning, which is easy to operate and easy to avoid obstacles; there are three mowing heights. The level is realized by adjusting the corresponding position of the support wheel and the frame. When working, the power is transmitted through the half-cross triangle tape, and the power output by the hand tractor is transmitted to the first grass cutter shaft, and then transmitted to the second grass cutter shaft. Two grass knife shafts, the grass knife shaft drives the grass knife on it to rotate at high speed, and finally realizes the mowing operation function; the compound double grass knife lawn mower has the characteristics of novel structure, safety and reliability, low cost, and automatic operation.

Description

Technical field [0001] The invention relates to a compound double-grass mower which can complete the operation process of corn and soybean weeding in the process of cultivating. 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 hazards, such as polluting crops, water sources and soil, etc. People and animals are prone to intractable dise...
