Combined ploughing and levelling all-in-one machine

Abstract

The invention discloses a combined ploughing and levelling all-in-one machine, and belongs to the technical field of farmland farming machines. The machine comprises a plow frame, a stubble breaking device, depth limiting wheels and a soil moisture filling implement, the plow frame is connected with a suspension part of a tractor through a suspension supporting plate arranged on a front-axle beam,and the stubble breaking device is arranged at the front end of the plow frame; a work roller of the stubble breaking device drives several stubble breaking cutters to rotate at the high speed for breaking crop stubble, and the work roller is driven by an upper speed changing box arranged on the front-axle beam of the plow frame through a transmission mechanism; a left side plow colter set and aright side plow colter set are respectively arranged on the left and right sides below the plow frame and staggeredly distributed in the longitudinal work direction, and the depth limiting wheels arearranged on longitudinal beams on the two sides of a rack; the soil moisture filling implement is arranged at the back end of the plow frame, and soil moisture filling and levelling are conducted on farmland turned over by the left side plow colter set and the right side plow colter set. The combined ploughing and levelling all-in-one machine can deeply plough and turn over the farmland and breakthe stubble of previous harvested crops simultaneously, the farmland can be levelled, and the sowing operation is conveniently conducted.

Description

technical field [0001] The invention relates to the technical field of farmland tillage machinery, in particular to a combined tillage machine. Background technique [0002] The traditional rotary tillage land preparation method requires multiple operations to properly bury the surface straw. At the same time, ordinary rotary tillage knives have poor crushing effect on corn stubble, and the land preparation operations are tedious, time-consuming and laborious. The use of rotary tillers to plow the farmland has low production efficiency, and the depth of tillage is limited by machinery. The working depth is generally about 15 cm, and the following parts are likely to cause soil compaction. At present, rotary tillers are often used in the two-cropping area of ​​North China for land preparation operations. Generally, two rotary tillers can meet the requirements for pre-sowing operations. The tractor has the disadvantages of many times of soil rolling, high power consumption, a...

Problems solved by technology

However, the function of the conventional plow used by a tractor is single, it is only deep plowing and deep plowing of the field without the function of leveling the field, and due to the existence of weeds in the field, the stubble of corn or other crops is relatively thick, which not only makes the conventional plow work It is easy to entangle the resistance of rattan and grass, and there is no crushed root stubble to cover the field, which will affect the emergence quality and yield of the next crop of wheat
