Embodiment 1

[0028] A three-dimensional corn stalk returning machine, mainly including a front frame 18, a rear frame 11, a straw picking device, a straw feeding device, a straw grinder 4, a stubble removal mechanism, a straw deep application device, a hydraulic control depth limiting mechanism and a hydraulic pressure control mechanism. Control system assembly, etc., the front frame 18 is connected to the rear frame 11 through the connecting frame 24, the front end of the front frame 18 is provided with a straw picking device, and the straw picking device includes a height adjustment An oil cylinder 19, a straw feeding device is arranged above the front frame 18, and the straw feeding device includes an automatic feeding gap adjustment mechanism 3, an upper feeding roller 2 and a lower feeding roller 1, between the two feeding rollers The front of the gap between the gaps is aligned with the exit of the straw picking device, and the rear is aligned with the entrance of the straw grinder 4....

Embodiment 2

[0030] The sprocket 21 of the straw picking device is arranged on the front part of the front frame 18, and the picking conveyor chain 29 is wound on the sprocket 21 and the sprocket coaxial with the upper feeding roller 2, and the rear motor 23 drives the upper The feeding roller 2 rotates, and the coaxial sprocket wheel of the feeding roller 2 drives the pick-up conveyor chain 29 to rotate, and the pick-up conveyor chain 29 drives the straw pick-up teeth 20 uniformly distributed on the pick-up conveyor chain 29 to complete the straw pick-up operation, and the pick-up height is adjusted by the oil cylinder 19 are hinged on both sides below the front frame 18 middle part, can change the push rod expansion and contraction amount of the height adjustment oil cylinder 19 by the hydraulic control system, realize the adjustment of the working height of the straw picking mechanism.

Embodiment 3

[0032] The straw feeding device is arranged in the middle of the front frame 18, the feeding gap automatic adjustment mechanism 3 includes a traveling gear and a pin connecting rod, and the feeding gap automatic adjustment mechanism 3 is arranged on the upper feeding roller 2 and the lower feeding roller 1 on both sides, when working, the rear motor 23 drives the upper feed roller 2 to rotate, the upper feed roller 2 drives the lower feed roller 1 to rotate, and the gap between the upper feed roller 2 and the lower feed roller 1 faces The outlet of the quasi-straw picking device is aligned with the entrance of the straw pulverizer 4. When the thickness of the straw layer changes, the upper feeding roller 2 can move up and down to adjust the size of the feeding gap, and ensure that the upper feeding roller 2 and the lower feeding roller The entering roller 1 turns in the opposite direction, so that the straw enters the straw grinder 4 smoothly.

Abstract

The invention relates to a maize straw three-dimensional returning machine which mainly comprises a front frame, a rear frame, a straw picking device, a straw feeding device, a straw crusher, a stubble cleaning mechanism, a straw deep placement device, a hydraulic control depth-limiting mechanism, a front motor, a rear motor, a hydraulic control system assembly and the like. The straw picking device is assembled at the front end of the front frame, the straw feeding device is assembled on the front part of the front frame, the straw crusher is assembled in the rear part of the front frame, the stubble cleaning mechanism is assembled below the front part of the rear frame, the straw deep placement device is assembled in the middle part of the rear frame, the hydraulic control depth-limiting mechanism is assembled in the rear part of the rear frame, the front motor is arranged on the front frame, the rear motor is arranged on the rear frame, and power is provided to the pre-posed motor and the post-posed motor by a hydraulic output system of a tractor. The maize straw three-dimensional returning machine during work is pulled by the tractor, and picks, crushes and deeply places the maize straws in a field as the tractor moves and meanwhile cleans stubbles, so that operations of ground mulching return to field, reclaimed soil return to field and soil deep placement return to field on the maize straws are realized.

Description

technical field [0001] The invention belongs to agricultural machinery, and in particular relates to a three-dimensional corn stalk returning machine used for crushing corn stalks in the field, removing stubble, and realizing the surface covering return of corn stalks, returning the field in the soil, and returning the corn stalks to the field with deep soil application. Background technique [0002] Most of the dry farmland in northern my country is facing the problems of water erosion and wind erosion of cultivated land soil. These problems cause a large loss of fine particulate matter, soil nutrients and organic matter on the soil surface, resulting in a decline in soil fertility. Covering the surface with crop straw and stubble can enhance the soil's ability to resist wind erosion, prevent the movement of soil particles, and help reduce sandstorms; returning straw to the field can increase the organic matter content of the soil and improve the soil structure; Soil seepag...
