[0002] At present, there are various types of straw-returning rotary tillers in China. For the dry-field straw-returning, most of them use the reversing of the coulter shaft to deepen the plowing layer, and use a sufficient amount of soil to cover the stubble grass, which increases the mechanical load and the mechanical damage rate. High, poor flatness in the field, it is very troublesome to change the forward rotation and the direction of the coulter rotary cutting when it is used in paddy fields, so it has not been widely used

Embodiment Construction
[0009] The straw-returning rotary tiller shown in Figure 1 and Figure 2 includes a gear box 3 fixed on the housing 2, a power transmission box 4 and a left arm 1, and the lower support of the power transmission box 4 and the left arm 1 At the two ends of the coulter shaft 5, a stubble cage 7 is arranged directly behind the coulter shaft 5, and the rolling of the stubble cage 7 depends on the traction force of the connecting plate 6 installed on the power transmission case 4 and the left support arm 1, In order to make the soil that escapes into the stubble cage 7 normally scatter on the stalks outside the grass cage 7, an agitator 8 is arranged in the stubble cage 7. The agitator 8 is a chain ring or other shape, and it can be rotated during operation. The knife rotates the soil and straw to the rear of the coulter shaft 5 at the same time. The straw is slender and light in specific gravity, and falls in front of the stubble pressing cage 7. It is rolled under the stubble press...

The invention discloses a rotary plow with a function of returning straws to fields. The rotary plow comprises a gear box, a power transmission box and a left support arm which are fixed on a case thereof. The two ends of a colter shaft are respectively supported by the lower parts of the power transmission box and the left support arm, a stubble pressing cage is provided right abaft the colter shaft, and a stirrer is provided inside the stubble pressing cage. When in operation, straws are rolled down by the stubble pressing cage; the soil that leaps into the stubble pressing cage is stirred out of the stubble pressing cage by the stirrer and normally spread on straws, therefore straw burying effect is good. When the rotary plow is used for rotary tillage of a paddy field, a paddy field rear wheel is provided, the stubble pressing cage presses the straws into slush, thus the rotary plow realizes the dual functions of returning straws to both the paddy field and a dry farmland. The rotary plow has simple structure and convenient operation, and can realize proper transformation and removal of stubbles in the dry farmland, which has good stubbles burying effect and is easy for popularization.
Description
Technical field [0001] The invention relates to an agricultural machine, in particular to a straw returning rotary tiller. Background technique [0002] At present, there are various types of straw-returning rotary tillers in China. For the dry-field straw-returning, most of them use the reversing of the coulter shaft to deepen the plowing layer, and use a sufficient amount of soil to cover the stubble grass, which increases the mechanical load and the mechanical damage rate. High, poor flatness in the field, and it is very troublesome to change the forward rotation and the direction of coulter rotary cutting when used in paddy fields, so it has not been widely used. Contents of the invention [0003] The purpose of the present invention is to provide a straw returning rotary tiller with simple structure. [0004] The technical proposal of the present invention is: comprise the gear box that is fixed on the housing, power transmission box and left arm, power transmission ...
