Preceding crawler travel tensioning apparatus have it is a variety of, it is more commonly used to there is leading screw to be tensioned and hydraulic track tension.
For leading screw strainer, after a certain position crawler tensioning, nut is locked by leading screw, when crawler belt is because of road condition change
After relaxing, it is impossible to which timely automated adjustment, hydraulic tensioning pressure are difficult to control, and hydraulic system breaks down or hydraulic oil occurs
During leakage, tensioning pressure can not ensure that crawler belt is constantly in tensioning state, cause slack of track, and then produce crawler belt and track frame
The failure such as interference wear or derailed crawler belt.
Utility model content
The purpose of this utility model is to provide the track takeup on a kind of sugar-cane cutting machine, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of crawler tensioning on sugar-cane cutting machine
Device, including plunger case, spring and guide wheel bracket, one end of the plunger case are provided with pouring orifice, inside the plunger case
Piston is installed, the plunger case is welded with walking chamber, and the walking chamber is provided with pressing plate in the inside by plunger case one end,
One end of the spring is connected with pressing plate, and spring bearer plate is provided with inside the other end of the walking chamber, the spring bearer plate
The other end of side and spring connects, and the guide wheel bracket is arranged on one end that walking chamber leans on spring bearer plate, the directive wheel
The other end of support is provided with guide wheel shaft, and directive wheel is provided with the guide wheel shaft.
Preferably, the plunger case and piston are sealed connection.
Preferably, the spring is to be flexibly connected with pressing plate, spring bearer plate.
Preferably, the spring applies pretightning force in advance before assembly, and the spring is compression spring.
Preferably, the directive wheel, guide wheel bracket, spring are demountable structure.
Compared with prior art, the beneficial effects of the utility model are：The utility model in plunger case one end by walking
The inside installation spring of chamber, by spring pre-tightening, makes device held stationary in the process of moving, ensures safety, at the same by
Before assembling, pretightning force is applied to spring, facilitates crawler belt to obtain appropriate tensioning, is also not in de- between driving wheel and crawler belt
Rail turns to the problem of difficult, by the way that spring is arranged to be flexibly connected with pressing plate, spring bearer plate, be easy to installation to device and
Dismounting, will be arranged to sealing structure between plunger case and piston, be easy to when adding butter to plunger case inside, internal pressure
Piston is set by the way that spring is used into compression spring, and to apply pretightning force before assembly to an end motion, facilitate crawler belt to obtain wet
The tensioning of degree, between driving wheel and crawler belt be also not in derailing or turn to the problem of difficult, while overall feel can be accurate
True measurement, pretightning force of the strainer to crawler belt can be accurately calculated, be easy to design and manufacture.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of track takeup on sugar-cane cutting machine,
Including plunger case 1, spring 2 and guide wheel bracket 3, one end of the plunger case 1 is provided with pouring orifice 4, inside the plunger case 1
Piston 5 is installed, the plunger case 1 is welded with walking chamber 6, and the walking chamber 6 is provided with the inside by the one end of plunger case 1
Pressing plate 7, one end of the spring 2 are connected with pressing plate 7, and spring bearer plate 8 is provided with inside the other end of the walking chamber 6, described
The side of spring bearer plate 8 is connected with the other end of spring 2, and the guide wheel bracket 3 is arranged on walking chamber 6 by spring bearer plate 8
One end, the other end of the guide wheel bracket 3 are provided with guide wheel shaft 9, directive wheel 10 are provided with the guide wheel shaft 9.
The plunger case 1 and piston 5 is are tightly connected, by butter is added inside plunger case 1, increasing the pressure of inside
Power, make piston 5 to an end motion；The spring 2 is to be flexibly connected with pressing plate 7, spring bearer plate 8, is easily installed and dismantles；Institute
State spring 2 and apply pretightning force in advance before assembly, facilitate crawler belt to obtain appropriate tensioning, also will not between driving wheel and crawler belt
Appearance is derailed or turns to the problem of difficult, and the spring 2 is compression spring, and overall rigidity can accurately measure, therefore
Pretightning force of its strainer to crawler belt can be accurately calculated very much, is easy to design and manufacture；The directive wheel 10, directive wheel branch
Frame 3, spring 2 are demountable structure, are easy to the Assembly And Disassembly maintenance to device.
