Abstract
A rotation of the roller chain adjustment tensioning device is characterized in that the device includes two side boards above the chain with one end rotatably arranged on a transplant rice seedlings machine, the rolling column of the pin is arranged between the two-side boards, and the pin is fixed on the two-side boards.
Description
Technical field:
The utility model relates to a kind of transplanter chain stretching device.
Background technique:
The tensioning of the built-in chain that hand transplanting machine is commonly used at present, because the narrow limitation on the spatial structure, the spring steel plates that adopt compress automatically, tension force is by the elasticity of spring steel and the mounting structure size decision of spring steel and chain, and is unadjustable, and such structural type proposes very high requirement to the rigidity selection of spring steel, the control of inner structure size, and the transmission resistance is big, chain easily extends, and impacting force is unfavorable for chain transmission and uses maintenance along with the elongation of chain constantly reduces.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and helps prolonging the chain life-span, reduces the roller type chain stretching device of the rotatable adjusting of transmission resistance.
Technical solution of the present utility model is:
A kind of roller type chain stretching device of rotatable adjusting is characterized in that: comprise that an end is loaded on the transplanter turnably and is positioned at the biside plate of chain top, the roller that is contained on the bearing pin is set between the biside plate, bearing pin is packed on the biside plate.
One end of biside plate is sleeved on the coupling shaft by rotating sleeve, and coupling shaft is packed on the transplanter body.
The utility model is rational in infrastructure, simple, is easy to the assembling maintenance, helps prolonging the chain life-span, reduces the transmission resistance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is Fig. 1 embodiment's user mode figure.
Fig. 3 is to use the state sectional view.
Embodiment:
A kind of roller type chain stretching device of rotatable adjusting, comprise that an end is loaded on the transplanter body 1 turnably and is positioned at the biside plate 3,4 of chain 2 tops, the roller 6 that is contained on the bearing pin 5 is set between the biside plate 3,4, and bearing pin 5 is packed on the biside plate 3,4 by cotter pin 9.One end of biside plate 3,4 is sleeved on the coupling shaft 8 by rotating sleeve 7, and coupling shaft 8 is packed on the transplanter body 1.
