The middle part of the front end of the front frame 11A supports a horizontal transmission shaft 3 , and the middle part supports a rotary tiller mechanism 14 . The middle part of power transmission shaft 3 is installed with the middle transmission box 2 that is directly connected with articulated gear box 1, and the side transmission box 4 that is connected with the cutter shaft 14-5 transmission of rotary tillage mechanism 14 is installed at both ends, so the power source can be articulated The rotary power drives the cutter shaft 14-5 of the rotary tillage mechanism through the articulated gear box 1-intermediate transmission box 2-transmission shaft 3-side transmission box 4. The two sides of the front frame 11A are respectively hinged with the lower end of the installation rod 6. The upper part of the installation rod 6 has a row of optional installation connection holes with the extension arm of the side transmission box 4, so the installation position can be selected as appropriate, and after being fixed with bolts, Form a stable triangular bracket structure.

The two ends of the cutter shaft 14-5 are respectively equipped with a rotary tiller 14-1 with the functions of ditching and inner soil cultivation and furrowing, and an anti-wrapping grass cover 14-6 is installed at the supporting part to prevent the rotary tiller shaft from leaving residues in the soil. The stalks rotate and twist, and are twisted into the installation gap between the side plate and the cutter shaft, causing the resistance of the rotary tillage to increase, and even the phenomenon that the cutter shaft is stuck. The middle part of cutter shaft 14-5 is equipped with radially paired circular column stick broken soil knife 14-2, square column stick broken soil knife 14-3 and fan-shaped spiral broken soil knife 14-4, these three kinds are in pairs The soil-breaking knives are arranged on the cutter shaft 14-5 in a manner that is uniformly distributed in the circumferential direction, axially spaced, and mutually misplaced. Practice has proved that the organic combination of three kinds of soil-breaking knives with different shapes and characteristics can respectively play the role of crushing soil, Soil cultivation can effectively solve the problems of poor crushing rate and inconsistent plowing depth in heavy clay soil.

The scraper 13 is installed behind the rotary tillage mechanism 14, and the front pressing roller 12 is supported by the middle frame 11M. During operation, the rotary tillage mechanism can be rotated and cut, and the plowed land can be scraped and flattened into a furrow surface, and then the furrow surface can be slightly pressed. Make it level.

The front end of the rear frame 11F is equipped with a set of sowing openers 15 and a group of modularized sowing devices 7 corresponding to the openers are supported in the middle.
