Farm machinery capable of crushing corn straw and returning the same to farmland

Abstract

The invention relates to an agricultural machine which can crush corn straw and achieve the effect that the corn straw can be crushed to be 2cm to 5cm in average so as to return the corn straw to the field. The agricultural machine is driven by a tractor and consists of a straw harvesting mechanism, a straw collecting mechanism, a straw delivery mechanism and a straw cutting mechanism and also solves the greatest problem in the present straw returning machine that since straw returning has poor effect and the straw after natural return is too long in length, some straws even being 40cm and different problems are then caused. However, after the straw is crushed to return to the field, the follow-up farming can not be affected due to the large length of the straw and no straw with too long length needs to be burned, thus the air quality can be improved and the soil structure and the fertilizer content in the soil can also be improved as a result of the increase of organic matters so as to reduce the using amount of fertilizer. In order to achieve the aim of design, during the process of research and development, designers solve the problems of the winding of the corn straw and the residual of the root of the corn straw. Meanwhile, the agricultural machine of the invention can also adapt to different tractors to form the series products by changing the width of working components.

Description

Technical field [0001] The invention is an agricultural machine capable of crushing corn stalks and returning them to the field. The corn stalks returned to the field by the machine can achieve an average crushing effect of 2-5 cm. technical background [0002] Corn stalk after autumn harvest was a good fuel in the past, and now it is a very important source of organic fertilizer due to the popularity of corn stalk returning to the field. However, the corn stalk returning machinery currently being used on a large scale has many shortcomings. The most important thing is that due to the poor treatment effect on the stalks, the corn stalks after returning to the field generally exceed 10 centimeters, and some such as leaves and individual corn stalks even exceed 40 centimeters, which have seriously affected the future. the depth of the cultivated land. And because the distance between the machine and the ground is large, the roots of the remaining corn stalks are very large. W...

[0002] Corn stalk after autumn harvest was a good fuel in the past, and now it is a very important source of organic fertilizer due to the popularity of corn stalk returning to the field. However, the corn stalk returning machinery currently being used on a large scale has many shortcomings. The most important thing is that due to the poor treatment effect on the stalks, the corn stalks after returning to the field generally exceed 10 centimeters, and some such as leaves and individual corn stalks even exceed 40 centimeters, which have seriously affected the future. the depth of the cultivated land

And because the distance between the machine and the ground is large, the roots of the remaining corn stalks are very large. When sowing, they will hinder the soil coverage of the wheat seeds, leaving the seeds exposed on the ground, which is not conducive to wheat germination, nor to future wheat resistance to lodging

The easiest way to do it now is to burn the corn stalks after returning the fields, which not only reduces the content of organic fertilizers in the soil and causes waste, but also causes serious air pollution
