Deep tillage rotary plow

Abstract

The invention relates to a deep ploughing rotary plow which consists of a frame assembly (1), a universal joint assembly (2), a suspension frame assembly (3), a transmission box assembly (4), a cutter shaft assembly (8), a hood (5), a side plate (7), and a rotary blade (9). The transmission box assembly (4) is arranged in the middle of the frame assembly (1). The transmission box assembly (4) is connected with the output shaft on the tail part of a tractor through the universal joint assembly (2). The output shaft of the transmission box assembly (4) drives the cutter shaft assembly (8) to rotate. The cutter shaft assembly (8) is provided with a rotary blade installation seat. The rotary blade (9) is installed on the cutter shaft assembly (8) through the rotary blade installation seat. The rotary blade (9) is a deep ploughing rotary blade. The rotary plowed soil not only reaches the international requirement of more than 25cm in depth, but also excesses current agricultural depth: 16-22cm greatly. According to the deep ploughed land by means of the technical means, the average depth of the plough layer is 28-35cm, and maximally 40cm.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a deep-plow rotary plow. Background technique [0002] Because the rotary tillage plow has the advantages of flat land, no rubbish, and fast farming speed, it is very popular among farmers; but because the common rotary tillage knife is 160 cm long, with a 90° straight bend, and is made of high carbon steel, the rotary tiller can be used during work. The action similar to "hoeing" makes the soil cultivation layer shallower by 10-15 cm; in addition, the ordinary rotary tiller gearbox is a three-stage variable speed, the output speed is 300 rpm, the gear module is 6, and the speed ratio is large, resulting in continuous work. When the temperature is too high, it needs to be shut down for cooling; therefore, after returning the straw to the field, the commercially available rotary plows distribute a large amount of straw on the soil surface, which affects the emergence rate of crops such...

[0002] Because the rotary tillage plow has the advantages of flat land, no rubbish, and fast farming speed, it is very popular among farmers; but because the common rotary tillage knife is 160 cm long, with a 90° straight bend, and is made of high carbon steel, the rotary tiller can be used during work. The action similar to "hoeing" makes the soil cultivation layer shallower by 10-15 cm; in addition, the ordinary rotary tiller gearbox is a three-stage variable speed, the output speed is 300 rpm, the gear module is 6, and the speed ratio is large, resulting in continuous work. When the temperature is too high, it needs to be shut down for cooling; therefore, after returning the straw to the field, the commercially available rotary plows distribute a large amount of straw on the soil surface, which affects the emergence rate of crops such as winter wheat, often resulting in difficult rooting of crops, lodging, pests and diseases. ; Due to the shallow plowing layer, repeated plowing and rolling should form repeated soil compaction, resulting in a decrease in soil organic matter content, insufficient fertility absorption, soil water seepage, reduced water storage capacity, increased surface runoff, and aggravated the process of soil erosion. The return rate is low and cannot supplement the nutrients needed for crop growth, eventually leading to soil degradation and affecting crop yields
