Description

The hand-held grain header

Technical field

The utility model relates to a kind of agricultural hand-held grain header.

Background technology

The hand-held grain header includes header, threshing tube, transmission device, road wheel, frame and power set, and its deficiency is:

1, because traditional road wheel includes housing, housing is provided with and helps kickboard, be provided with closure plate in the housing, closure plate is provided with axle sleeve, also be provided with the retaining mechanism that is used to be installed on the grain header output shaft on housing and the axle sleeve, help kickboard to be generally a plurality of triangle iron plates that constitute by two iron plates, when walking on land, when the top of triangle iron plate was positioned at the vertical line at housing center, the road wheel horizontal level was the highest, when housing center vertical line is positioned at the center of two triangle iron plates, the road wheel horizontal level is minimum, road wheel is fluctuated, and the utmost point is not steady, and long-time shake damages transmission case easily; When walking in the paddy field, because the iron triangle apex area is little, the pressure that acts on the paddy field is big, makes road wheel sink into to cause inconvenient walking in the mud in paddy field.

2, since general clutch comprise lid is arranged, platen, diaphragm spring, friction plate, shock-absorbing spring and splined hub, platen and diaphragm spring are riveted on and cover, friction plate is between power wheel and platen, the installation steel disc of friction plate is radially contacting with damping spring, in the damping spring splined hub, its complex structure, production cost height, the operation principle complexity is not easy to maintenance.

3, owing to traditional threshing tube includes a frame, threshing screw feeder, collection grain screw feeder, a transmission mechanism, is arranged on charging aperture, stalk outlet and grain export on the frame, stalk outlet operated by rotary motion two sides or all be arranged on frame the place ahead about the tube frame with charging aperture, when stalk outlet is positioned at the left and right sides or front, paddy leaf after the threshing can be gone in the field of the right and left or front, if the field of the right and left or front is not harvesting also, can influence the grain harvest of the right and left or front.

4, because traditional header includes header frame, straw shift wheel, harvester, collection standing grain screw feeder and transmission device, header and threshing tube generally are fixed together, header and threshing cylindrical shell are long-pending bigger, are to install or dismantle all to waste time and energy, and are not easy to transportation and use.

5, owing on the grain header crane is not set generally at present, the threshing tube directly is fixed on the frame, header is installed on the threshing tube, need the high Rui of paddy of harvesting inconsistent, the height of header differs and satisfies the height of paddy surely, header is too high, can cause paddy to be sheared too highly, causes waste.

The utility model content

The purpose of this utility model just provides a kind of hand-held grain header simple in structure, with low cost, and it can make grain header steadily walking on land, and walking avoids road wheel over head and ears in the earth in the paddy field.

The purpose of this utility model is to realize by such technical scheme, it includes header, the threshing tube, transmission device, road wheel, frame and power set, road wheel includes housing, housing is provided with and helps kickboard, be provided with closure plate in the housing, closure plate and housing surround enclosed cavity, axle sleeve one end is fixed on housing bottom, the other end is fixed on the closure plate, help kickboard to include multi-disc walking blade, every walking blade all is fixed on housing outer surface, and the housing axle center is not all by every walking plane, blade place, annular is strengthened the walking muscle blade of will walk and is connected in aggregatesly, strengthens the outer edge that the walking muscle protrudes from the blade of walking.

During assembling, axle sleeve is placed on the grain header output shaft, is higher than the walking blade owing to strengthen the height of walking muscle, grain header is to contact with ground by strengthening the walking muscle when walking on land, and it is circular strengthening the walking muscle, rolls steadily, makes grain header smooth running on land; When grain header is walked in the paddy field, because the walking blade has angle in housing, no matter housing is rolled into what angle blade of can avoiding walking and contacts with the line in paddy field, increase the contact area in walking blade and paddy field, and be enclosed cavity in the housing, buoyancy is big, makes the walking blade be difficult for being absorbed in the paddy field.

Owing to adopted technique scheme, the utlity model has following advantage: 1, grain header can steadily be walked on land, avoids grain header to be absorbed in the paddy field; 2, clutch configuration is simple, and is with low cost, and operation principle is succinct, is convenient to maintenance; 3, the threshing tube is convenient to the integral body harvesting on state ground, threshing good separating effect; 4, header installation, convenient disassembly are convenient to transportation and are used, and be simple in structure; 5, crane is simple in structure, can regulate the harvesting height of header, is convenient to harvesting.
