Abstract
The utility model discloses a kind of bar cropper, comprise body, driving machine, described driving machine drives crank rotation by gear, what described bent axle connected is the connecting rod of reciprocating, be provided with bearing shell between connecting rod and bent axle, the top of connecting rod is provided with cutting off tool, it is characterized in that: the side of described connecting rod is fixed on body by extension spring.By the way, what the utility model can reduce when connecting rod moves back and forth is spacious dynamic.
Description
Technical field
The utility model relates to metal cutting technical field, particularly relates to a kind of bar cropper.
Background technology
At present, bar cropper common on market adopts brace and connecting rod framework, bent axle drivening rod reciprocating in gearbox, the top of connecting rod is mounted with cutting off tool, owing to being provided with bearing shell between connecting rod and bent axle, machine is in long-time use procedure, bearing shell easily weares and teares, and there will be larger fit clearance between connecting rod and bent axle, easily occurs spacious dynamic, accelerate the wearing and tearing of parts, produce larger noise.
Utility model content
It is low that the technical problem that the utility model mainly solves is to provide a kind of operating noise, the bar cropper of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of bar cropper, comprise body, driving machine, described driving machine drives crank rotation by gear, and what described bent axle connected is the connecting rod of reciprocating, is provided with bearing shell between connecting rod and bent axle, the top of connecting rod is provided with cutting off tool, it is characterized in that: the side of described connecting rod is fixed on body by extension spring.
The utility model preferably technical scheme is: be fixed on body by extension spring on the upside of described connecting rod.
Due to the effect of extension spring, prevent connecting rod from occurring because of the wearing and tearing of bearing shell sagging, thus reduce the operating noise of machine.
The beneficial effects of the utility model are: it is low that the utility model has operating noise, the advantage of long service life.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, body 2, bent axle 3, connecting rod 4, cutting off tool 5, extension spring.
Detailed description of the invention
Below in conjunction with accompanying drawing to embodiment further instruction.
As shown in Figure 1, a kind of bar cropper, comprise body, driving machine, described driving machine is rotated by gear band dynamic crankshaft 2, and what described bent axle 2 connected is the connecting rod 3 of reciprocating, is provided with bearing shell between connecting rod 3 and bent axle 2, the top of connecting rod 3 is provided with cutting off tool 4, is fixed on body 1 on the upside of described connecting rod 3 by extension spring 5.
Under the effect of extension spring 5, the spacious dynamic of connecting rod 3 reciprocating can be reduced, improve the service life of machine
It is low that the bar cropper of this spline structure has operating noise, the advantage of long service life.
