Embodiment Construction

[0009] A straw returning machine suitable for various row spacing operations, such as figure 1 As shown, the frame 1 is fixed longitudinally with two support beams 11, the traction frame 2 is sleeved on the support beams 11, and a first adjustment device 7 is provided between the frame 1 and the traction frame 2, Described first adjustment device 7 is made of lead screw nut adjustment device, when rotating the hand wheel that is fixed on screw mandrel like this, can make traction frame 2 move along support beam 11, thereby can adjust the relative position of traction frame and frame, and then Adjust the relative position of the tractor and the straw returning machine, so it can be properly adjusted according to the different row spacing of the crops under different planting agronomic conditions, which not only ensures the field passability of the tractor, but also ensures that the straw returning machine will not cross the field ridge , thus enhancing the agronomic adaptabilit...

Abstract

The invention discloses a straw returning machine that is applicable to operations for a plurality of row spacings. The main technical points are that: at least two support beams are fixedly arranged on a stander along a vertical direction, a traction frame sleeved on the support beams, a first adjusting device that can enable the traction frame to move along the support beams is arranged between the stander and the traction frame, the stander is fixedly provided with track along a longitudinal direction, a second adjusting device that can enable a first transmission device to move along the track is arranged between a tank body of the first transmission device and the stander; a coupling is arranged between an output shaft of the first transmission device and an input shaft of a second transmission device, allowing the output shaft of the first transmission device and the input shaft of the second transmission device change relative positions at axial direction. According to the different row spacings of crops under different planting and agricultural conditions, the coupling can appropriately adjust the relative positions of the tractor and the straw returning machine, thereby not only ensuring the trafficability of the tractor in the field, but also ensuring that the straw returning machine not cross the ridges of the field, so as to enhance the agriculture adaptability of the straw returning machine.

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. After years of extensive investigations, most returning machines are mainly used to crush corn stalks, and corn is planted in a variety of ways, such as interplanting before wheat harvest, on-demand or live broadcast afte...
