Fig. 3 is the A of Fig. 1 to enlarged view.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the utility model includes hand brake 1, main shift lever 2 and main shift lever control
Mechanism 3 processed, hand brake 1 include brake handle 11 and handle set 12, and 11 right end of brake handle and 12 upper end of handle set are hinged, hand
12 lower end of handle seat is fixed in handle set fixed plate 4.5 left end of bracing wire that brakes is hinged with 11 middle part of brake handle, and right end passes through hand
It is hinged with 6 upper end of swing arm after handle seat fixed plate 4.Swing arm 6 is located on the outside of gearbox, and lower end is hinged with gear box 7.Brake
8 left end of bracing wire resetting spring is hooked on the upper end of swing arm 6, and right end is hooked on the bearing 91 on cab frame 9.
Main shift lever control mechanism 3 includes back middle bracing wire 31,32, the two control bracing wires 33 of displacement frame and control bracing wire
Resetting-mechanism 34,2 lower end of main shift lever are fixedly connected with displacement frame 32, and displacement frame 32 is centrally through displacement frame rotating shaft 35
Hinged with operation panel 10,10 lower end of operation panel is weldingly fixed on cab frame 9.Bracing wire 31 is disposed side by side on brake and draws in returning
The right side of line 5, left end and 11 middle part of brake handle are hinged, and right end is divided after passing through handle set fixed plate 4 by swivel pin 36
Not hinged with the lower end of two control bracing wires 33, the upper end of two control bracing wires 33 is hinged with the both ends of displacement frame 32 respectively, and
The control bracing wire hinge joint for shifting 32 left and right ends of frame is equal at a distance from 35 axle center of displacement frame rotating shaft, and adjusts two controls
The length of bracing wire 33 processed is allowed to equal, when ensureing back that middle bracing wire 31 pulls swivel pin 36 to move down, as shown in Figure 2 two controls
Bracing wire 33 is in the state for tensing displacement frame 32, and HST can not provide power, to lock main shift lever 2, avoid driving
Member's maloperation.
It includes controlling bracing wire resetting spring 341 and control bracing wire resetting spring mounting bracket 342 to control bracing wire resetting-mechanism 34,
It includes arch bar 343, supporting rod 344 and lower fixed seat 345 to control bracing wire resetting spring mounting bracket 342, and control bracing wire resets bullet
341 upper end of spring is hooked on the upper end of arch bar 343, and the lower end of arch bar 343 is fixed on the middle part of lower fixed seat 345, lower solid
345 lower end of reservation is weldingly fixed on cab frame 9, and supporting rod 344 is horizontal in the upper end of lower fixed seat 345.Such as Fig. 3 institutes
Show, the lower end of control bracing wire resetting spring 341 is hooked on swivel pin 36, and 31 other end of bracing wire passes across supporting rod 344 in returning
Lower end by swivel pin 36 and two control bracing wires 33 is hinged.
As shown in Figure 1, when pushing brake handle 11 is in the horizontality of inoperative, brake bracing wire 5 and time middle bracing wire 31
It moves down respectively, swing arm 6 is swung to the right under the elastic force effect of brake bracing wire resetting spring 8, and brake block unclamps main shaft in gearbox.
Meanwhile swivel pin 36 moves up under the resilient force of control bracing wire resetting spring 341, so that gearbox shifts 32 liang of frame
The control bracing wire 33 at end is in relaxed state, and driver can freely operate the back-and-forth motion of main shift lever 2 at this time, manipulate harvesting
Machine moves forward and backward.
As shown in Fig. 2, when needing parking braking, upper lift brake handle 11, brake handle 11 drives brake bracing wire 5 simultaneously
It is moved up with middle bracing wire 31 is returned, the elastic force that brake bracing wire 5 pulls swing arm 6 to overcome brake bracing wire resetting spring 8 is swung to the left, makes change
Brake block locking main shaft in fast case, to realize the braking of gearbox.Meanwhile bracing wire 31 pulls swivel pin 36 to overcome control in returning
The elastic force of bracing wire resetting spring 341 moves down, and to tense two control bracing wires 33, displacement frame 32 is controlled respectively because of its both ends
Bracing wire 33 is tensed and cannot be rotated, and main shift lever 2 is firmly locked on centre position, to make harvester firmly stay
Vehicle is on the slope.Control bracing wire resetting spring 341 and brake bracing wire resetting spring 8 are in tensioning state at this time.
Harvester is again started up constantly, if driver forgets to unclamp hand brake 1, since main shift lever 2 is firm
Jail is locked on centre position, can not move main shift lever 2, and HST cannot start, and harvester remains at parked state.
In addition, when needing emergency braking such as harvester, no matter main shift lever 2 is in any position, upper lift brake handle
11, two control bracing wires 33 of the tension of bracing wire 31, displacement frame 32 are locked on horizontal position in time, thus by main shift lever 2
Simultaneously centerlock is retracted, the power of HST can be cut off while skidding, harvester is made to stop in shorter time
Walking.
In addition to the implementation, the utility model can also have other embodiment, all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, is all fallen in the protection domain of the requires of the utility model.
