Straw smashing, stubble cleaning and rotary cultivation integrated machine

Abstract

The invention discloses a straw smashing, stubble cleaning and rotary cultivation integrated machine, and is applied to straw smashing, stubble cleaning and rotary cultivation integrated machines. By the aid of the straw smashing, stubble cleaning and rotary cultivation integrated machine, problems that each existing rotary cultivation blade is platy and is bent towards a side to form a transverse blade, corn stubble can be effectively cut but two rotary cultivation shafts respectively provided with rotary cultivation blades with long shanks and short shanks are required in order to effectively smash the corn stubble on the ground can be solved. The straw smashing, stubble cleaning and rotary cultivation integrated machine comprises a transmission mechanism (8). The transmission mechanism is connected with a stubble cleaning and rotary cultivation rotary shaft (9) and a straw smashing rotary shaft (11), rotary cultivation blades (10) with alloy cutter bits are mounted on the stubble cleaning and rotary cultivation rotary shaft and are spirally arranged, shanks of the rotary cultivation blades with the alloy cutter bits comprise straight shank bodies (1) and curved shank heads (2), shank web sides of the curved shank heads are in the shapes of concave curves (5), shank back sides of the curved shank heads are in the shapes of convex curves (6), and the alloy cutter bits (3) are inlaid at the ends of the shank web sides of the curved shank heads.

Description

Technical field: [0001] The invention relates to an integrated machine for crushing and removing stubble with rotary tillage. Background technique: [0002] Rotary tillage is a method of soil preparation using a rotary tiller. The depth of rotary tillage is generally not too deep, that is, 10-30 cm, so that the cutter can chop the soil to achieve the effect of crushing the soil and making pulp. It is suitable for paddy fields paddy. However, the corn stubble left in the soil in the corn field is not as easy to be broken as the soil clods, so people have designed rotary blades that can chop the corn stubble step by step, and can also rotate the land at the same time. Existing rotary tillage blades are all flaky and bent to one side to form a horizontal blade, which can effectively cut corn stubble. Since the blade needs to be bent sideways, the thickness of the blade must be relatively thin, and in order to effectively crush the corn on the ground For stubble, two rotary ti...

Problems solved by technology

In addition, corn stalks are generally crushed and sprinkled on the field at the same time after the autumn harvest of corn at this stage. Since the degree of crushing of corn stalks is limited, it cannot be returned to the field directly, nor can it be crushed and rotated with the above-mentioned traditional two-axis rotary tiller. Farmers Generally, the corn stalks are collected and dried in the sun until they are burned and returned to the field during spring plowing, and then the stubble is removed and rotary tillage is carried out.

This operation can not carry out the autumn stubble removal rotary tillage, and the burned straw pollutes the environment and causes smog
