Example Embodiment

[0010] Attached below figure 1 , Attached figure 2 The specific implementation of a double-row corn harvester with a hydraulic side tilting and unloading grain in the grain tank of the present invention is further described: the diesel engine (25) is started, and the power of the diesel engine (25) is installed on the diesel engine pulley (35). The V-belt is transmitted to the oil pump (36) one way to drive the oil pump (36) to work, and output high-pressure oil to provide power for the hydraulic system; the other way is transmitted to the travel clutch (26), which is controlled and separated by the clutch pedal (28) When combined, the clutch shaft (56) drives the clutch shaft drive sprocket (27) installed at its left end to rotate, and the power is transmitted to the intermediate wheel (53) through the chain, and the intermediate wheel (53) transmits the power to the The gearbox inputs the sprocket (19) to provide power for the whole machine to travel; the power of the diesel engine (25) is also transmitted to the joint pulley (32) through the joint V-belt installed on the diesel engine pulley (35), The harvesting clutch lever (38) controls the tension of the linkage V-belt assembled on the linkage pulley (32) through the harvesting clutch wheel (33), thereby controlling the separation and combination of harvesting power. When combined, the belt wheel shaft is connected. (55) Drive the driving sprocket (31) installed at its left end to rotate, and transmit the power to the intermediate wheel (21) through the chain. The intermediate wheel (21) transmits the power to the intermediate wheel (18) through the chain. (18) The power is transmitted to the header power input sprocket (10) through the chain, which drives the header power input shaft (11) and the header power driving sprocket (58) and the cutting knife power driving chain installed at its right end The wheel (59) rotates, and the header power driving sprocket (58) transmits the power through the chain to the transmission box right transmission sprocket (52) installed on the right side of the header transmission box (7), driving the front output end The stalk pulling roller (6) rotates to realize the ear picking operation during harvest, and at the same time drives the reel driving sprocket (51) installed on its upper part and the left driving sprocket (50) of the transmission box installed at its left end to rotate; The sprocket (51) drives the reel chain (3) through the reel driven sprocket (2) to realize the reeling operation during harvest; the left driving sprocket (50) of the transmission box transmits the power to the steering roller through the chain The drive sprocket (49) drives the ear roller (48) to rotate, and the chain drives the ear pressing roller (46) to rotate, so as to realize the pressing operation when the ears are peeled; the right drive sprocket (52) of the transmission box passes the chain at the same time The power is transmitted to the power input sprocket (54) of the peeling machine installed on the right end of the power input shaft (47) of the peeling machine, which drives the power input shaft (47) of the peeling machine to rotate, and the bevel gear installed in the middle drives the peeling machine to rotate. The peeling roller (45) on the frame (20) rotates to realize the peeling operation during harvest; the cutting knife power drive sprocket (59) transmits the power through the chain to the cutting knife power follower installed on the intermediate wheel shaft (60) The sprocket (61) drives the intermediate wheel shaft (60) to rotate, and a set of reversing gears (62) drives the hob (8) to rotate, and the straw is chopped under the interaction of the hob (8) and the fixed knife (9).
[0011] When the machine is running, step on the clutch pedal (28) to realize the disengagement of the traveling clutch (26), and the auxiliary transmission lever (37) is engaged with the main transmission lever (41) to engage the gear, and the clutch pedal (28) is released to realize the traveling clutch ( 26) Engage, the drive wheels (17) installed on the drive shafts at both ends of the traveling gearbox (16) drive the whole machine to travel; the steering wheel (39) controls the rear axle guide wheel assembly (34) to realize the left and right steering of the main engine.
[0012] The working process of the machine for corn harvesting is: when the corn harvester enters the field and prepares for work at working speed, first control the movement of the header lifting cylinder (14) through the hydraulic joystick (40), so that the header passes the slider (57) in The frame (15) rises or falls in the straight slot at the front, and at the same time, it rotates around the fixed shaft (13) under the action of the connecting rod (44) installed at the rear of the peeling frame (20) to adjust the header to the proper At height, operate the harvest clutch lever (38) to make the harvest clutch wheel (33) press the link V-belt, rotate the link pulley (32), and drive the tassel picking, cutting, peeling, tassel shifting and tassel pressing mechanism to rotate. The corn harvester is hung on the walking block, and is aligned with the corn in the field. The crop divider (1) at the front of the header lifts up the fallen corn stalks, and feeds the corn stalks into the relatively rotating stalk-drawing roller through the straw chain (3) (6) In the middle, the straw moves backwards and downwards, the corn stalk is chopped by the interaction of the rotating hob (9) and the fixed knife (9), the ears are picked off through the ear picking plate (4), and the The grain chain (3) transports the ears to the peeling machine, and the relatively rotating peeling roller (45) peels the ears, and at the same time, the ears are transported back to the ears by the rotation of the ear picking roller (48) and the ear pressing roller (46). In the box (24), when the ear box (24) is full, the turning cylinder (23) is operated by operating the hydraulic control handle (40) to turn the ear box (24) to the left, and the ear box (24) is loaded into the transport vehicle. Then manipulate the pressing control handle (40) to reset the ear box (24) to the working state, that is, complete the whole process of a working cycle.
