Description

A kind of small-sized corn combine transmission assembly

Technical field

The utility model relates to a kind of walking tractor matching with small-sized corn combine transmission assembly, belongs to mechanical field.

Background technology

At present, in China corn combine field, mainly contain two kinds of types: a kind of is the Backpack-type maize combine, and its speed changing structure is from supporting four-wheel tractor, another kind is the self-propelled corn combine, its speed changing structure mostly links with front driving axle, and the present domestic professional and complete enterprise that has produces this transmission assembly specially, this transmission assembly not only is used in corn combine, also can be used for wheat, rice harvester, but its design is complicated, cost is higher.At present, the existing maize sown area of China is suitable substantially with the wheat planting area, but cultivated area and soil regime vary again, as everyone knows, China is a large agricultural country, peasant's soil occupancy volume per capita is few, except soil, some areas more concentrated, other area soil occupancy volume of each family usually only has several mu, large-scale reaping corn machinery can't use at all, the large-scale corn combine of single production, be difficult to adapt to China's national situation, simultaneously China governments at all levels are to the support on policy of reaping corn machinery and continue to increase financial support, for the Application and Development of small-sized corn combine provides wide space, it is very huge to produce small-sized corn harvesting machinery market potential, decades have been promoted and popularized to existing domestic hand tractor, the volume of holding of peasant's hand tractor is considerable, therefore developing a kind of small-sized corn combine transmission assembly and walking tractor matching uses, solve the demand that most of peasants gather in corn, be very necessary, its market prospects are also very considerable.

Summary of the invention

The small-sized corn combine transmission assembly that provides a kind of walking tractor matching to use is provided the utility model purpose, it is mainly by gearbox body, the final drive shaft assembly, snapping bar output shaft assembly, dialing-grain unit output chain gear shaft assembly, the straw cutting assembly is formed, its architectural feature is as follows: be equipped with the dialing-grain unit drive bevel gear on the final drive shaft, straw cutting drive bevel gear, the snapping bar drive bevel gear, the elevator driving gear, final drive shaft is by bearings at both ends and adjust bearing cap and oil seal seat is assemblied on the gearbox body, adjust on the bearing cap and be equipped with the adjustment bolt, in the gearbox body outside, be equipped with power input pulley, the elevator driving gear, snapping bar driving gear shaft and snapping bar driven axle are assemblied on the gearbox body by bearing, snapping bar driving gear shaft and the engagement of snapping bar drive bevel gear, the snapping bar driving gear is assemblied on the snapping bar driving gear shaft, the snapping bar driven gear is assemblied on the snapping bar driven axle, the snapping bar driving gear is meshed with the snapping bar driven gear, two dialing-grain unit power output gear axles are assemblied on the gearbox body by bearing and dialing-grain unit oil seal seat, be meshed with the dialing-grain unit drive bevel gear at final drive shaft two ends respectively, two dialing-grain unit drive sprockets are assemblied on the dialing-grain unit power output gear axle, straw cutting output shaft is assemblied on the gearbox body by bearing and straw cutting supporting base, straw cutting power output bevel gear is assemblied in an end of straw cutting output shaft, be meshed with the straw cutting drive bevel gear on the final drive shaft, the straw cutter mount is assemblied in the other end of straw cutting output shaft, and the straw cutter are assemblied on the straw cutter mount

Because the utility model has adopted said structure, optimize, simplified the structural design of the covert box assembly of small-sized corn combine, the use of this covert box assembly, make the supporting small-sized corn combine compact conformation that on hand tractor, uses, transmission of power is reliable, steady, solved the needs of peasant, alleviated peasant's reaping corn operations labor intensity greatly fritter field reaping corn.

Embodiment

Below in conjunction with accompanying drawing 1, accompanying drawing 2, the embodiment of 3 pairs of the utility model small-sized corns of accompanying drawing combine transmission assembly is further described: behind diesel engine starting, its power is with on the power input pulley (13) that is delivered on the small-sized corn combine transmission assembly by the belt pulley on the diesel engine flywheel by V, so just, realized the transmission of hand tractor power driving shaft (8) in small-sized corn combine transmission assembly, because of elevator driving gear (14) is assemblied in middle driving shaft (8), power just is delivered on the elevator by the elevator driven gear that is meshed with it like this, when driving shaft (8) rotates, the snapping bar drive bevel gear (10) that is assemblied on the driving shaft (8) is also rotated together, driven the snapping bar driving gear shaft (11) that is meshed with it simultaneously, snapping bar driving gear (2) is assemblied on the snapping bar driving gear shaft (11), snapping bar driven gear (4) is assemblied on the snapping bar driven axle (3), snapping bar driving gear (2) is meshed with snapping bar driven gear (4), when snapping bar driving gear shaft (11) rotates, snapping bar driving gear (2) also rotates together, driven the snapping bar driven gear (4) that is meshed with it simultaneously, the final rotation that drives snapping bar driven axle (3), because of snapping bar driving gear shaft (11) and snapping bar driven axle (3) are connected by gear, its switched in opposite, forming snapping bar driving gear shaft (11) clockwise rotates, snapping bar driven axle (3) rotates counterclockwise, make two to pluck cob and turn to the inside simultaneously, drive snapping bar, just can reach and squeeze the purpose of plucking corncob, when driving shaft (8) rotates, the two dialing-grain unit drive bevel gear (5) that are assemblied on the driving shaft (8) are also rotated together, the two dialing-grain unit power output gear axles (16) that are meshed have with it been driven simultaneously, two dialing-grain unit drive sprockets (17) are assemblied on the dialing-grain unit power output gear axle (16), like this, dialing-grain unit drive sprocket (17) just drives the rice-pulling chain bar by the dialing-grain unit driven sprocket and rotates together, cause two its conical surfaces of dialing-grain unit drive bevel gear (17) are towards gearbox body (1) center line, when driving shaft (8) is done when clockwise rotating, (shown in accompanying drawing 3) right side dialing-grain unit power output gear axle (16) is just done and is rotated counterclockwise, and left side dialing-grain unit power output gear axle (16) is done and is clockwise rotated, thereby when making both sides rice-pulling chain bar do respectively counterclockwise and clockwise rotate, so just realized the purpose that two rice-pulling chain bars inwardly rotated and stirred corn stalk respectively, when driving shaft (8) rotates, the straw cutting drive bevel gear (9) that is assemblied on the driving shaft (8) is also rotated together, driven the straw cutting power output bevel gear (18) that is meshed with it simultaneously, straw cutting output shaft (19) also rotates together, final drive is assemblied in the rotation of the straw cutter (21) on the straw cutter mount (22), plays the effect of cutting corn stalk.
