Vertical-horizontal combined dry land rotary cultivating, stubble cleaning and straw burying machine

Abstract

The invention discloses a vertical-horizontal combined dry land rotary cultivating, stubble cleaning and straw burying machine and aims at solving the problems that an existing rotary cultivator is single in function, poor in transmission effect, relatively small in tilling depth during operation on dry land, large in resistance during straw burying, and low in operation efficiency. The vertical-horizontal combined dry land rotary cultivating, stubble cleaning and straw burying machine comprises a vertical rotary cultivating and stubble cleaning device arranged at the bottom of a front segment of a rack and a transmission device, wherein a power input end of the transmission device is connected with a power device of a tractor and a power output end of the transmission device is connected with the vertical rotary cultivating and stubble cleaning device. The vertical-horizontal combined dry land rotary cultivating, stubble cleaning and straw burying machine is characterized in that a horizontal rotary cultivating, stubble cleaning and straw burying device is arranged at the bottom of a rear segment of the rack; the power output end of the transmission device is connected with the horizontal rotary cultivating, stubble cleaning and straw burying device. The vertical-horizontal combined dry land rotary cultivating, stubble cleaning and straw burying machine is simple in structure, good in transmission effect, suitable for dry land operation and relatively small in tilling depth; the resistance on a blade during straw burying is reduced, the functions of rotary cultivation, soil crushing, stubble cutting and cleaning and straw burying can be completed once, the operation frequency of the machine is reduced and the farming efficiency is improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a vertical and horizontal combined dry land rotary tillage, stubble removal and grass burying machine. Background technique [0002] The reasonable disposal of crop straw is a major problem in the agricultural field of our country. The phenomenon of straw burning has been repeatedly banned, and it is difficult to implement the ban. Straw recycling improves the requirements for the state of straw when crops are harvested, and increases the difficulty of harvesting machines. At the same time, straw recycling machines need to go to the ground twice, which increases energy consumption and makes soil compaction more serious. Straw returning treatment uses corresponding machines to chop straw and stubble after harvesting crops and sprinkle them on the soil surface or bury them in the soil, which not only improves the physical and chemical properties and structure of the soil, but also reduce...

Problems solved by technology

[0003] In order to solve the problem of straw returning to the field, many straw returning machines and key component designs of straw returning machines have appeared in recent years, such as the invention patent 201610156300 "A Rotary Tiller for Straw Returning Without Grass Wrapping", Utility Model Patent ZL200710141508.3 "Paddy Field Stubble Burying Rotary Tiller", Utility Model Patent ZL200820214707.2 "Paddy Field Straw Burying Rotary Tiller", Invention Patent ZL201210514851.9 "Flood and Dry Dual-purpose Straw Returning Knife Roller" and Invention Patent ZL201410436141. 8 "Combined straw returning rotary tiller roller", etc., but these machines are mainly used in paddy field straw returning operations, the transmission effect is not good, the plowing depth is shallow when working on dry land, and the resistance encountered when the straw is buried is large. Low efficiency, multiple operations are required to meet the sowing requirements of later crops
