Description
Technical field
The present invention relates to mechanical device more particularly to a kind of chain stretching devices of earth's surface batcher.
Background technique
On current market the chain stretching device of earth's surface batcher there are several types of, one is directly with screw rod outward
Top；Second is pulled outward with rubber-spring complex and screw combinations,；The third is exactly to use helical spring and screw combinations toward drawing；With
Upper several situations, the first belongs to rigid link, does not have the effect of buffering, and chain engagement is also bad, wears also than very fast；The
Two kinds and the third all need nonstandard spring customized, some are high for manufacturing cost, require installation space also bigger when being tensioned outward
It is some；And be exposed for a long time, dust is had above, certain damage is caused to spring, shortens its service life.
Summary of the invention
The present invention overcomes the shortcomings of that background technique provides a kind of chain stretching device of earth's surface batcher, designs and develops this
The purpose of device: filling a shield outside the butterfly spring group of standard, and it is not contaminated and collided to can be well protected spring
The damage being subject to afterwards, prolongs the service life.
The present invention provides following technical proposals: a kind of chain stretching device of earth's surface batcher, which is characterized in that described
Chain stretching device includes screw rod 1, spring base 2, the butterfly spring group 3 connecting with the spring base 2, shield 4, axle sleeve 5, described
Screw rod 1 and 5 threaded engagement connection of axle sleeve, the butterfly spring group 3 are placed in the sheath 4, and the screw rod 1 runs through the butterfly
The center of shape groups of springs 3, one end of the axle sleeve 5 are fixedly connected with described 3 one end of butterfly spring group, the shield 4 it is another
End is equipped with plug 11, and 3 other end of butterfly spring group is fixedly connected with the plug 11, the axle sleeve 5 by backstand 6 and
Rack is fixed.
Working principle: making to compress butterfly spring group 3 backward with the backstand 6 of its threaded engagement by rotary screw 1, thus
Make butterfly spring group 3 have a thrust on spring base 2, then power is passed to by screw rod 1 by whole device and realizes tensioning
Effect；
The chain stretching device two sides are equipped with slide 7, and the slide 7 is along [ shape sliding slot 12 is slidably connected.
Beneficial effects of the present invention: shield 4 protects spring to avoid the erosion by dust, the deep peace for falling spring of spring base 2
Fill more convenient, Novel chain tensioning apparatus simplifies manufacture difficulty, significantly reduces the manufacture of earth's surface batcher core component
Cost shortens the manufacturing cycle, and maintenance work is made to become simpler, has saved the space of tail portion, and equipment is made to start to convey
Better buffer function is obtained when material, without often adjusting tension screw, sprocket wheel and chain can be made preferably to engage, greatly
Improve the reliable utilization rate of equipment.Novel chain stretching device can make equipment dependability be greatly improved, and can extend
The service life of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of chain stretching device of the present invention.
Fig. 2 is the left view of Fig. 1.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described with specific embodiment.
Fig. 1, in 2: screw rod 1, spring base 2, butterfly spring group 3, shield 4, axle sleeve 5, backstand 6, slide 7, bearing 8, chain
Take turns 9, axis 10, plug 11, [ shape sliding slot 12.
A kind of chain stretching device of earth's surface batcher, the chain stretching device include screw rod 1, spring base 2, with it is described
The butterfly spring group 3 of the connection of spring base 2, shield 4, axle sleeve 5, the screw rod 1 and 5 threaded engagement connection of axle sleeve, the butterfly
Shape groups of springs 3 is placed in the sheath 4, and the screw rod 1 runs through the center of the butterfly spring group 3, one end of the axle sleeve 5 and institute
3 one end of butterfly spring group is stated to be fixedly connected, the other end of the shield 4 is equipped with plug 11,3 other end of butterfly spring group with
The plug 11 is fixedly connected, and the axle sleeve 5 is fixed by backstand 6 with rack.
Working principle: making to compress butterfly spring group 3 backward with the backstand 6 of its threaded engagement by rotary screw 1, thus
Make butterfly spring group 3 have a thrust on spring base 2, then power is passed to by screw rod 1 by whole device and realizes tensioning
Effect.
The chain stretching device two sides are equipped with slide 7, and the slide 7 is along [ shape sliding slot 12 is slidably connected.
The chain stretching device of earth's surface batcher drives transmission belt to make conveying movement by the rotation of axis 10, the axis 10
Both ends are equipped with bearing 8, and the present apparatus achievees the purpose that its tensioning of entire conveying device by the both ends of takeup shaft 10 simultaneously.
