Abstract
The utility model discloses a seat frame assembly of a walking tractor. The seat frame assembly of the walking tractor comprises a seat frame body (5), a connecting plate (2), a toothed plate shaft (6), a toothed plate seat (7), a fixed press plate (9) and a movable press plate (10). The connecting plate (2) is fixed on an oblique opening of the seat frame body (5) in a welded mode, a handle bracket assembly (3) is fixed on the connecting plate (2), a coulter gearbox body (1) is fixed on the lower portion of the connecting plate (2), the toothed plate seat (7) is arranged on the seat frame body (5) through the toothed plate shaft (6), the fixed press plate (9) is fixedly connected with the seat frame body (5), a plowing tail wheel assembly (8) is fixed on the fixed press plate (9) through the movable press plate (10), and a seat assembly (11) is fixed on the plowing tail wheel assembly (8). The seat frame body (5) is in an inverted-U-shaped groove structure, and a lining plate (4) is fixed in a groove opening of the seat frame body (5) in a welded mode. Due to the structure, the seat frame assembly of the walking tractor is simple and compact in structure, convenient to disassemble and assemble, small in size, light in weight, low in production cost, short in turning radius and the like, and the whole walking tractor is enabled to be more flexible and convenient to operate and have better mobility.
Description
Technical field
The utility model relates to a kind of hand-held tractor mounting sub-assembly, and particularly a kind of hand tractor connects the suspension connection device of rotovator, ploughing tail wheel assembly and seat assembly.
Background technology
Hand tractor is the agriculture cultivation machinery of farming operation, because of characteristics such as it have that the hack ability is strong, the earth's surface is smooth after the rotary tillage, and is widely used.But there is following defective in the mounting sub-assembly of existing 121 type hand tractors in operation process: the one, because hanging by screw, fagging is fixed on the base frame body, the fagging requirement of strength is high, fixed screw can produce looseningly in operation process, affects rotary tillage process.The 2nd, complex structure, the dismounting of mounting sub-assembly is inconvenient.The 3rd, need for fixing, the U-shaped front notch of base frame body needs wider width, forms front wide and rear narrowly, and punching process character is relatively poor, because volume is larger, will greatly increase the weight of base frame body, the increase product cost.As seen notch has a strong impact on the presentation quality of product with weld seam after the liner plate welding up in addition.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have so far desirable product to emerge.
Summary of the invention
The defects that exists for overcoming existing hand tractor mounting sub-assembly, the purpose of this utility model provide a kind of simple and compact for structure, easy accessibility, volume is little, lightweight, production cost is low, radius of turn is little hand tractor mounting sub-assembly.
The utility model solves the problems of the technologies described above the technical scheme that adopts, it comprises base frame body, connecting plate, tooth plate axle, tooth plate seat, fixation clip and movable pressing board, described connecting plate is weldingly fixed on the angle of base frame body, the handle bracket sub-assembly is fixed on the top both wings of connecting plate, the colter gearbox body is fixed on the bottom of connecting plate, the tooth plate seat is arranged on the base frame body by the tooth plate axle, fixation clip is fixedly connected with base frame body, the ploughing tail wheel assembly is fixed on the fixation clip by movable pressing board, and seat assembly is fixed on the ploughing tail wheel assembly.
Described base frame body is inverted U groove structure, is welded with liner plate on the inverted U notch of base frame body.
After adopting said structure, compared with prior art have the following advantages and effect, the one, because base frame body is inverted U groove structure, connecting plate is weldingly fixed on the angle of base frame body, the handle bracket sub-assembly is fixed on the top both wings of connecting plate, connecting plate and base frame body are connected firmly, handle bracket sub-assembly easy accessibility.The 2nd, owing to the improvement of mounting structure, reduced the volume of base frame body, alleviated weight, reduced cost.The 3rd, because base frame body reduces, reserved usage space, after suitably improving associated components, can make the radius of turn of 121 type hand tractors reduce 14 centimetres, whole hand tractor handled more flexible, mobility is better.
