In an additional preferred embodiment, the locking system includes swivel plate 4, the side and first of the swivel plate 4
Articulated arm 2 is pivotally connected, and the third articulated arm 5 runs through the swivel plate 4 far from one end activity of its drive-connecting shaft, and by being located at rotation
The nut of 4 two sides of rotating plate with swivel plate 4 is detachable is fixedly connected.The swivel plate 4 includes shaft 41 and fixes with shaft 41
Second articulated arm 42 of connection, the shaft 41 wear first articulated arm 2, pass through nut locking.As Fig. 3 (compresses in figure
Spring 8 is not shown) shown in, the second articulated arm 42 of plate structure can remain in rotary course to hang down with third articulated arm 5
Directly, compared to the structure of kidney slot, face contact is changed to by original point contact, increases and is connect with nut and third articulated arm 5
Contacting surface product, is tightened securely, is prevented nut and third articulated arm 5 from skidding, is increased the stability of device.In the embodiment, second
Articulated arm 42 is rotatablely connected by shaft 41 and the first articulated arm 2, and third articulated arm 5 and the second articulated arm 42 are rotatablely connected, into
And connect indirectly with the first articulated arm 2, three linkage structures are formed, any articulated arm rotation can all drive other two articulated arms
Rotation.Therefore, third articulated arm 5 rotates, and the second articulated arm 42 and the linkage of the first articulated arm 2 is driven, to control Pulley shaft 3
Position, realize belt tension, and third articulated arm 5 is fixed on the second articulated arm 42 by nut, first can be fixed
The position of articulated arm 2, the second articulated arm 42, third articulated arm 5 is realized the positioning of Pulley shaft 3, is installed compared to by driven wheel
The mode of crawler travel test is carried out after good again, the utility model is swift to operate, convenient for the transmission in harvester installation process
Adjustment, saves the set-up time.Secondly, the first articulated arm 2, the second articulated arm 42, third articulated arm 5 and pedestal 1 form triangle
Shape structure increases the stability of belt tension tooling, and harvester overall operation is more stable, reliable, improves walk test
As a result precision.
In the present embodiment, the angle of the third articulated arm 5 and pedestal 1 is 16~24 °, first articulated arm 2 and base
The angle of seat 1 is 10~80 °.Three slewing equipments of the utility model mutually restrict, and limit the maximum tension degree of belt,
It avoids the first articulated arm 2 from excessively rotating around pedestal 1, and generates excessively high tensile force, cause belt tearing.As Fig. 3~4 (are pressed in figure
Contracting spring 8 is not shown) shown in, under original state, the angle of the third articulated arm 5 and pedestal 1 is α 2, α 2=24 °, described the
The angle of single-revolution arm 2 and pedestal 1 is α 1, α 1=80 °, and belt is in minimum tensioning state at this time, when third articulated arm 5 is to leaning on
When nearly 1 side of pedestal rotation, drive the first articulated arm 2 close to pedestal 1, rotating to third articulated arm 5 and the angle of pedestal 1 is α
4, α 4=16 °, the angle of the first articulated arm 2 and pedestal 1 is α 3, and when α 3=10 °, belt be in maximum tension state at this time, leads
Driving wheel and 3 spacing of Pulley shaft are 2 times under minimum tensioning state.
In the present embodiment, the fixed plate 7 and swivel plate 4 are made of upper metal plate, lower metal plate and damping layer, described to subtract
The layer that shakes is set between upper metal plate and lower metal plate.
In the present embodiment, the damping layer is made by foam metal, and foam metal has certain intensity, rigidity, extension
Property and additive property, due to foam metal have certain strength and stiffness, can support third articulated arm 5；Secondly, foam metal contains
There is foam stomata, when foam metal bears pressure, the forced area caused by stomata collapses increases and material strain hardening
Effect, so that foam metal has the characteristic of excellent absorption impact.When harvester carries out walk test, fuselage has larger
Vibration, therefore deformed by the hysteresis of damping layer to dissipate or absorb the energy of the input device, the vibration for reducing device is anti-
It answers, loosens or collapse so that three linkage structures be avoided to generate, increase the stability of device.
In the present embodiment, compressed spring 8 is set on the third articulated arm 5, described 8 one end of compressed spring abuts locking
Device, the other end pass through nut locking.Increasing compressed spring 8 can further absorb and reduce the vibration during walk test
And impact, increase the stability of device, and the mode that nut is fixed, can by adjusting nut in the position of third articulated arm 5,
Change the compression degree of compressed spring 8, so as to adjust the stress size of compressed spring 8, adapts to the absorption vibration under varying environment
With the requirement of impact energy.Although compressed spring 8 also has itself secondly, vibration and impact can be absorbed in compressed spring 8
It moving back and forth, the movement of compressed spring 8 is transmitted to foam metal, it is consumed by the hysteresis deformation of foam metal, meanwhile, foam
The displacement transfer of metal can also be consumed to compressed spring 8 by the deformation of compressed spring 8；Therefore, pass through 8 He of compressed spring
The synergistic effect of foam metal, can cancel out each other mutual deformation impact, even if so that the device field uneven road surface into
When row walk test, it is also able to maintain stabilization.
In the present embodiment, adjusting bracket 6, the adjusting branch are equipped between first articulated arm 2 and the Pulley shaft 3
Frame 6 is bolted on the first articulated arm 2.The axis direction of the adjusting bracket 6 is equal with first articulated arm 2
Row.The size of adjusting bracket 6 is designed as different sizes according to the structure of different type of machines, only needs to change adjusting bracket when replacing type
6.By replacing adjusting bracket 6, the production of adaptation more multi-model is applied widely, practical.Secondly, being bolted
Mode it is easy to disassemble, be convenient for changing adjusting bracket 6.
To skin when the belt tension tooling of the utility model is in addition to can be used for crawler travel test in harvester installation process
Band tensioning, it may also be used for the tensioning of driving wheel and the driving belt between moving in turn is equipped with, by Pulley shaft 3 as tensioning
Wheel, is mounted on belt side.The tensioning apparatus of current each producer leads to tensioning degree not to be changed substantially, working range it is small
High rotary speed movement easily causes tensioning wheel to loosen to belt in the process for a long time, so that transmission belt be made to relax again, seriously affects
Transmission efficiency；Secondly, belt tension degree immobilization, can not adjust, adaptability and exchange according to different use environments
Property is poor, does not adapt to the production of more types.The belt tension tooling of the utility model is opened by the adjustment of three linkage structures
Clamp force degree and magnitude of tension are adjustable, can adjust the position of Pulley shaft 3 at any time with the tightness of belt, are adjusted by replacement
Bracket 6 is saved, the belt tension for adapting to more multi-model is fixed, and adjusting space needed for strainer is smaller, convenient manual operation.
