Abstract

The utility model relates to the driver's cab of the transport cart transferred from a small tractor, which is characterized in that the internal side of the door of the driver's cab is provided with the hand-operated opening or closing device of the window glass. In order to further improve operating conditions, the front window is provided with a hand-operated windscreen wiper, seats are provided with elastic cushions.

Description

The operator's compartment of compact tractor modification transport plane

The utility model relates to general vehicle, the window of vehicle cab particularly, and Windshield, door or allied equipment, also relevant with other vehicle body fittingses not to be covered or parts, in International Patent Classification (IPC), be B6OJ, B60S.

On the basis of walker tractor, the compact tractor modification transport plane of resolute design more and more is subjected to user's welcome.This type is divided into two kinds, and one is the formula of bowing, and two is whole rack.The latter can be divided into f-w-d and back-wheel drive two classes again.No matter what kind has all adopted easy operator's compartment, the wind glass of both sides respectively is two, passes wherein one and open, and ventilation volume only is half of window ara.Ventilation volume is little, has uncomfortablely become the tractor driver and requires improved place.

Task of the present utility model provides a kind of operator's compartment of compact tractor modification transport plane, and it is control ventilation and more comfortable easily.

Task realizes by following scheme: compact tractor modification transport plane has frame at least, operator's compartment, the compartment, the driving engine of front and back wheel and frame front, the hand control setup that it is characterized in that the operator's compartment wind glass, promptly in the door inboard rocking handle is housed; fixing miniature gears on the crank shaft; this gear is meshed with the sector rack that is fixed with initiatively rocking arm; initiatively rocking arm has axle around volute spiral spring near the end (upper end) of sector rack; the middle part intersects and is connected with driven rocking arm; the upper end of driven rocking arm has short slide-bar; and be arranged in the chute hole of the fixed slip bar that is fixed on the vehicle window lower edge; main; the lower end of driven rocking arm; respectively have short slide-bar and lay respectively in the chute hole at connecting rod two ends, said connecting rod is fixed on the lower edge of wind glass.

In order further to improve riving condition, manual windshield wiper and spring cushion can also be set.

Manually windshield wiper is positioned on the front screen, and its rain wiping plate touch glass, and the middle part is connected with driving lever, and the outer end of driving lever and handle links to each other and extension spring is arranged.

The below of spring seat cushion is a metal bin, and its upper strata is a foamed plastic, and lower floor is wooden base plate, and the centre is the sofa spring, and whole appearance is coated with the artificial leather lining.

Make model machine by such scheme, through probationary certificate, it is big to have easy control ventilation and amount, and glass is non-friable, the rain retracement line is clear, seat is driven advantages such as comfortable.

Accompanying drawing 1 is a complete machine scheme drawing of the present utility model, and Fig. 2 is a wind glass manual setter among Fig. 1; Fig. 3 is a manual wiper scheme drawing among Fig. 1; Fig. 4 is a seat cushion scheme drawing among Fig. 1.

Below in conjunction with accompanying drawing embodiment is described.

The driving engine 2 that compact tractor modification transport plane has frame 7, operator's compartment 3, compartment 9, front-wheel 1, trailing wheel 8 at least and is loaded on frame 7 front portions.Rocking handle 4 is equipped with in the door inboard of operator's compartment 3, fixing miniature gears 10 on the axle of this handle, and be meshed with the sector rack 11 of fixing initiatively rocking arm 13, initiatively rocking arm 13 has axle 12 around volute spiral spring, middle part to intersect near an end of sector racks 11 to be connected with driven rocking arm 14 so that minor axis is active.The upper end of driven rocking arm 14 has short slide-bar, and is arranged in the chute hole of fixed slip bar 16.Said fixed slip bar 16 is fixed in the lower inner wall of car door, and the lower end of initiatively rocking arm 13 and driven rocking arm 14 respectively has short slide-bar, and lays respectively in the chute hole at connecting rod 15 two ends, and the connecting rod 15 here is fixed on the lower edge of wind glass 17.

Working process: shake rocking handle 4, miniature gears 10 rotates thereupon, drives the sector rack 14 and the initiatively rocking arm 13 that are engaged with.Because miniature gears 10, volute spiral spring axle 12, fixed slip bar 16 are fixed on the door, driven rocking arm 14 will change along with the rotation of miniature gears 10 with the angle of initiatively rocking arm 13 this moment, and its lower end respectively with short slide-bar, in the chute hole separately of connecting rod 15 two ends, slide simultaneously.Along with the variation of angle, short slide-bar promotes connecting rod 15 or descends, thereby wind glass 17 is risen or falls.In this example, be that wind glass 17 descends the volute spiral spring rolling-in when miniature gears 10 rotates counterclockwise; Otherwise wind glass 17 rises, and volute spiral spring discharges, and can borrow the spring release force to overcome the gravity of segment glass and become hand light like this.

Manual wiper 5 is set, can keeps tractor driver's sight line clear when rainy.Manually wiper 5 is fixed on the front window.Rain wiping plate 21 touch with glass, and its middle part is connected with driving lever 20, and the other end of driving lever 20 links to each other with the outer end of handle 18, and with extension spring 19.The effect of extension spring 19 is to keep the suitable association of rain wiping plate 21 and glass.

The quality of seat cushion 6 is related to tractor driver's labor condition.This routine seat cushion 6 is positioned at the top of metal bin 26, and its surface layer is a foamed plastic 22, and bottom is wooden base plate 25, and the centre is equipped with sofa spring 23, and outside face is coated with artificial leather lining 24.
