Embodiment Construction

[0009] A straw returning machine suitable for various row spacing operations. As shown in FIG. There is a first adjustment device 7 between the traction frame 2, and the first adjustment device 7 is composed of a screw nut adjustment device, so that when the hand wheel fixed on the screw rod is rotated, the traction frame 2 can be moved along the support beam. 11 moves, so that the relative position of the traction frame and the frame can be adjusted, and then the relative position of the tractor and the straw returning machine can be adjusted, 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 tractor. The field passability also ensures that the straw returning machine will not cross the field ridge, thus enhancing the agronomic adaptability of the straw returning machine.

[0010] As shown in Fig. 1 and Fig. 2 together, described frame 1 is longitudinally fixedly provide...

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...
