Abstract

The utility model discloses an adjustable riding seat frame of a hand tractor, which comprises a fixing frame (9) which is fixed on a main machine (8), a lifting operating device for steering, a tail wheel (1), a riding seat tube (5), a vibration reducing spring steel plate (6) and a riding seat (7), wherein, the riding seat (7) is fixed on the riding seat tube (5) through the vibration reducing spring steel plate (6). The lifting operating device for steering is composed of a tail wheel fork (2), a tail wheel inner tube (3), a screw rod, nuts, a tail wheel outer tube (4) and a lifting handle (11). The tail wheel (1) is positioned on the tail wheel fork (2), and the riding seat tube (5) is fixed at the tail wheel outertube (4). A riding seat joint (10) is fixed between the fixing frame (9) and the tail wheel outer tube. After the adoption of structure, when a machine tool with a small longitudinal size is in operation, a wheelbase can be shortened by adjustment to reduce a curve radius, and the steering performance of a machine set can be improved, and steering resistance and steering operating force of the machine set can be reduced; accordingly, the abrasion of a steering system of the machine set can be reduced. The utility model has advantages of simple and reasonable structure, convenient use and installation, firm and reliable connection, etc.

Description

Walker tractor is adjustable takes advantage of mounting

Technical field

The utility model relates to a kind of mounting of taking advantage of, the matching used mounting of taking advantage of during particularly a kind of walker tractor farming.

Background technology

At present, the walker tractor that uses in the society takes advantage of mounting generally to adopt the tail wheel top that the frame mode of taking advantage of seat is set, its tail wheel links to each other with the tail wheel outer tube by pipe and screw mandrel, nut in tail-wheel fork, the tail wheel, taking advantage of seat to be fixed on by the damper spring steel plate takes advantage of on the pipe, take advantage of a pipe to be fixed on the tail wheel outer tube, rocking-turn tail wheel lifting handle can be adjusted the height of taking advantage of seat liftoff; Fixed form has two kinds, a kind of is that the tail wheel outer tube directly is fixed on the rotovator at walker tractor rear portion, this kind mode can take advantage of seat taking advantage of on the mounting when the rotary tillage operation, but when operations such as ploughing, rake, harrow-like implement for pulverizing soil, removed to make because of rotovator and taken advantage of mounting fixing nowhere, the tractor driver can only the walking operation, increases tractor driver's labour intensity.Another kind is that the tail wheel outer tube is captiveed joint with main frame by fixed mount, its work tool rotovator, plough, rake, harrow-like implement for pulverizing soil etc. all are installed in the below of fixed mount, distance between tail wheel and the main frame can only be determined with the longest facility of longitudinal size, present walker tractor is generally determined the distance of tail wheel and main frame and the length of fixed mount with the length of plough, when with the little facility operation of longitudinal sizes such as rotovator, rake, harrow-like implement for pulverizing soil, just seem that tail wheel and main frame distance is excessive, cause turn radius excessive, be unfavorable for that the tractor driver operates.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing walker tractor takes advantage of mounting to exist, the utility model provide a kind of simple and reasonable, the service-strong walker tractor is adjustable takes advantage of mounting.The technical scheme that its technical matters that solves the utility model adopts comprises the fixed mount that is fixed on the main frame, turns to lifting operating control, tail wheel, takes advantage of seat pipe, damper spring steel plate and takes advantage of seat, taking advantage of seat to be fixed on by the damper spring steel plate takes advantage of on the pipe, the described lifting operating control that turns to is made up of pipe, screw mandrel, nut, tail wheel outer tube and lifting handle in tail-wheel fork, the tail wheel, tail wheel is arranged on the tail-wheel fork, take advantage of a pipe to be fixed on the tail wheel outer tube, between fixed mount and tail wheel outer tube, be fixed with and take advantage of the seated connection head.

After adopting said structure, when using the little facility operation of longitudinal size, adjustable short fixed mount reduces the wheelbase of walker tractor work tool, reduce turn radius, improve the turning efficiency of unit, because wheelbase shortens the cornering resistance and the handling maneuver power that can reduce unit, and then reduce the wearing and tearing of unit steering swivel system; Have advantages such as simple and reasonable, easy to install and use, firm and reliable connection.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Shown in Figure 1, be the adjustable specific embodiments of taking advantage of mounting of the utility model walker tractor, comprise the fixed mount 9 that is fixed on the main frame 8, turn to the lifting operating control, tail wheel 1, take advantage of seat pipe 5, damper spring steel plate 6 and take advantage of the seat 7, taking advantage of seat 7 to be fixed on by damper spring steel plate 6 takes advantage of on the seat pipe 5, the described lifting operating control that turns to is by tail-wheel fork 2, pipe 3 in the tail wheel, screw mandrel, nut, tail wheel outer tube 4 and lifting handle 11 are formed, tail wheel 1 is arranged on the tail-wheel fork 2, take advantage of seat pipe 5 to be fixed on the tail wheel outer tube 4, between fixed mount 9 and tail wheel outer tube 4, be fixed with and take advantage of seated connection head 10.When using the less agricultural machinery and implement of longitudinal size, detachably take advantage of seated connection head 10, directly captive joint with fixed mount 9 end faces, shorten wheelbase, minimizing cornering resistance, raising turning efficiency.Throttle control handle 12 and turning to is shaken hands and is with the soft cover of moulding respectively on 13 among the figure, and make throttle control handle 12 and turn to comfortable, the good hand touch of texture when shaking hands 13 operations, and can be anti-skidding, antirust, increase the service life.

Claims

1, a kind of walker tractor is adjustable takes advantage of mounting, comprise the fixed mount (9) that is fixed on the main frame (8), turn to the lifting operating control, tail wheel (1), take advantage of seat pipe (5), damper spring steel plate (6) and take advantage of the seat (7), taking advantage of seat (7) to be fixed on by damper spring steel plate (6) takes advantage of on the seat pipe (5), it is characterized in that: the described lifting operating control that turns to is by tail-wheel fork (2), pipe (3) in the tail wheel, screw mandrel, nut, tail wheel outer tube (4) and lifting handle (11) are formed, tail wheel (1) is arranged on the tail-wheel fork (2), take advantage of seat pipe (5) to be fixed on the tail wheel outer tube (4), between fixed mount (9) and tail wheel outer tube (4), be fixed with and take advantage of seated connection head (10).
