Abstract

The invention discloses a straw returning machine that is convenient for different crops, comprising a stander, a first transmission device arranged on the top part of the stander and a second transmission device arranged at the side part of the stander which can drive a grinding knife-roller to rotate. An output shaft of the first transmission device is connected with an input shaft of the second transmission shaft; the first transmission device consists of a gear box that can transmit power vertically and is arranged at the middle part of the stander. On the premise of guaranteeing the crushing rate, the invention can endow the grinding knife-roller with different rotating speed through simple operation according to the crushing difficulty of the crop straw, which not only reduces the power consumption of a tractor, but also saves time and labor for no belt or belt wheel is needed to be dismantled.

Description

technical field [0001] The invention relates to the technical field of straw returning machines, in particular to a traction-type straw returning machine suitable for use in connection with a rear power output shaft of a tractor. Background technique [0002] The straw returning machine is an agricultural machine that crushes the harvested grain crop straw and sprinkles it on the ground. When the tractor is moving forward, it presses down the crop straw, and then crushes it through the rotating hammer claw or hammer blade, and then passes through It is buried in the ground by rotary tillage or deep plowing, which is not only beneficial to the accumulation of organic fertilizer in the soil, but also solves the environmental pollution caused by burning straw. At present, the straw returning machine is mainly used to crush corn stalks, but with the popularization and application of the straw returning machine, it has been applied to the straw crushing of weeds and crops such as...
