[0025] Working principle: The working principle of the orchard green manure cutting and rolling machine during the rolling of green manure in the orchard is as follows. During operation, the machine is first pulled behind the tractor through the three-point suspension frame (28), and then the torque of the power output shaft of the tractor is transmitted to the coupling (6) through the cross shaft universal coupling. The coupling (6) transmits power to the gearbox (25) through the rotating shaft (27). The main pulley (11) on the gearbox (25) transmits power to the two groups of obliquely arranged cutting device transmission pulleys (8) and rotary soil breaker transmission pulleys (10) through V-belts, respectively. Before the machine is started, the depth limiting wheel (24) is adjusted in advance so that the green manure rolling device reaches a depth of 15-20 cm. During the operation in the orchard, the plowshare (29) cuts the earth ridge, and the raised earth ridge and green manure stems are broken and turned to the plow furrow by the rolling wall (22). The transmission shaft (5) connected to the cutting device transmission pulley (8) by a key drives the knife shaft fixing cylinder (4), the grass rope fixing cylinder (3) and the circular fixed knife disc (31) to rotate at high speed, which in turn drives the cutting and crushing blades (2) and the flexible grass rope (1) on them to rotate. The cutting and crushing blades (2) impact and cut the roots of the green manure crops and lift them upwards, and the flexible grass rope (1) impacts and crushes the flexible stems on the upper part of the plants. The two green manure cutting devices rotate in the same direction, and the stems are impacted and crushed by the two circular fixed knife discs (31) at the meshing position and are transported to the rear green manure rolling device. The rotary soil breaker transmission pulley (10) on the right rear side of the green manure rolling device drives the soil breaking transmission shaft (20) connected by a key to rotate, which in turn drives the soil breaking blade fixing plate (19) and the three groups of soil breaking blades (18) bolted to the plate to rotate at high speed to impact and crush the soil clumps and green manure residues. Since the green manure crushed stems have a higher water content and a higher density than the fine soil particles of the soil breaking blades (18), the green manure stems fall into the plow furrow dug by the rolling wall (22) before the soil particles, achieving uniform coverage of the green manure crushed stems with soil particles. Finally, the roller fixing frame (14) at the tail of the main frame and the roller connecting frame (16) below it drive the roller (17) to compact the uneven ground surface between the rows, and the spring shock absorber (15) bolted to the roller fixing frame (14) can also adjust the compaction degree of the soil according to the undulations of the ground surface. The machine can realize the processes of cutting, rolling and flattening the ground surface of the green manure in the orchard in one operation, which speeds up the natural decomposition of the green manure and fertilizes the field.
[0026] The structure and working principle of the utility model are described above with specific embodiments, and the utility model is not limited to the above embodiments. According to the above description, any modification, equivalent replacement, improvement and the like made on the basis of the spirit and principle of the utility model should be included in the protection scope of the utility model.
