A straw deep application device for straw returning machine

Abstract

The invention discloses a straw deep application device for a straw returning machine, which belongs to the technical field of agricultural machinery and includes a support assembly, a variable speed transmission assembly, and a deep plow assembly. The support assembly is located at the top of the whole set of devices. One side is provided with a variable speed transmission assembly, and a deep plowing assembly is provided under the support assembly. The invention is scientific and reasonable, and safe and convenient to use. The density of the upper straw or the operating speed of the cultivator can be used to adjust the operating efficiency of the deep tillage component. The pressure rod first penetrates into the soil at one end, and then presses the other end into the soil, so that the resistance of the deep tillage component into the soil is small, and it is conducive to equipment maintenance. The device uses a pressure rod to press the straw into the deep soil, which is beneficial to the degradation of the straw and improves the quality of the deep soil.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw deep application device for a straw returning machine. Background technique [0002] Returning straw to the field is an important way to increase the content of organic matter in the soil. In the prior art, the soil will be loosened by a cultivator, and part of the straw will be buried in the soil while loosening the soil to improve the degradation efficiency of the straw. The existing technology can only continuously improve the fertility of the shallow soil, but the crops will also absorb nutrients from the deep soil during the growth process. If it goes on for a long time, the nutrients in the deep soil will gradually lose, which is not conducive to the growth of crops. The design of the components enables the device to quickly adjust the operating efficiency of the deep plowing components. The pressure rod first penetrates into the soil at one end, and ...

[0002] Returning straw to the field is an important way to increase the content of organic matter in the soil. In the prior art, the soil will be loosened by a cultivator, and part of the straw will be buried in the soil while loosening the soil to improve the degradation efficiency of the straw. The existing technology can only continuously improve the fertility of the shallow soil, but the crops will also absorb nutrients from the deep soil during the growth process. If it goes on for a long time, the nutrients in the deep soil will gradually lose, which is not conducive to the growth of crops. The design of the components enables the device to quickly adjust the operating efficiency of the deep plowing components. The pressure rod first penetrates into the soil at one end, and then presses the other end into the soil, so that the resistance of the deep plowing components into the soil is small, and it is conducive to equipment maintenance. , after the operation of deep burying straw is completed, under the jacking motion of the eccentric wheel, the transmission column moves upward, and the pressure rod moves upward. Then it is pulled out slowly, the pressure rod can be rotated up and down to reduce the resistance of the soil, which is beneficial to the deep plowing component to be pulled out from the soil after deep plowing. This device uses the pressure rod to press the straw into the deep soil, which is beneficial to the straw. Degradation, improving the quality of deep soil, and the design of the pressure rod can swing up and down, so that the pressure rod is greatly reduced by the resistance of the soil, which is conducive to the operation efficiency of the equipment, so people need a straw deep application device for the straw returning machine solve the above problems
