Abstract
The utility model discloses a novel chain box safety clutch of a rice transplanter. Specifically, a chain wheel provided with a clutch jaw is divided into two parts, namely a clutch jaw provided with external threads and a hollow chain wheel provided with internal threads. The size for the clutch jaw provided with the external threads to combine with a chain wheel shaft is completely consistent with that of the chain wheel provided with the clutch jaw, and when the hollow chain wheel provided with the internal threads and the clutch jaw provided with the external threads are assembled together, chain teeth lean to the center of a chain box. The novel chain box safety clutch has the advantage that the improved chain teeth of the chain-driven safety clutch are positioned in the center of the chain box. According to the novel chain box safety clutch, the design, manufacturing and mounting complexity of the chain box and other components matched with the chain box are simplified.
Description
Technical field
The utility model relates to multiple rice transplanter, and specifically a kind of Novel rice transplanter chain box overload clutch belongs to agricultural mechanical field.
Background technology
At present, various rice transplanters are in farmland operation, more and more, for preventing that fortuitous event from damaging moving component, substantially all design and installation overload clutch, chaindriven overload clutch, usually by the sprocket shaft that is contained on the chain box, be contained on the sprocket shaft axial location, the sprocket wheel that can rotate relative to axle (band clutch dental inlay), with can slide vertically, but second half clutch dental inlay that must rotate with axle, and the spring that two half-clutch dental inlays are compressed, and the nut of the fixing spring other end.These parts are contained on the chain box because size, and the chain box center is departed from the sprocket center of sprocket wheel.This has increased difficulty to manufacturing and designing of chain box and other relevant parts.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of Novel rice transplanter chain box overload clutch, departs from the chain box center for the sprocket center of sprocket wheel, and a kind of scheme of passing through hollow sprocket wheel change sprocket position that addresses the above problem is provided.
The technical solution of the utility model is:
Sprocket wheel with the clutch dental inlay is divided into two parts, is with externally threaded clutch dental inlay and tapped hollow sprocket wheel.With the size of externally threaded clutch dental inlay and sprocket shaft combination, in full accord with clutch dental inlay chain size of wheel, tapped hollow sprocket wheel and is with sprocket deflection chain box center after the externally threaded clutch dental inlay assembling.
The utility model has the advantage of:
Because the chain box center is departed from the sprocket center of original sprocket wheel.This has increased difficulty to manufacturing and designing of chain box and other relevant parts.Chaindriven overload clutch sprocket after the improvement is in the chain box center.Simplified the complexity of design, manufacturing and the installation of chain box and other parts that match with it.
Description of drawings
Fig. 1 is the front structural representation of improvement of the utility model embodiment;
Fig. 2 is the structural representation after the improvement of the utility model embodiment;
Among the figure: 1-sprocket shaft, 2-are with externally threaded clutch dental inlay, the tapped hollow sprocket wheel of 3-, 5-round nut, 6-Compress Spring, 7-axial location back-up ring.
Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Embodiment
Sprocket wheel with the clutch dental inlay is divided into two parts, is with externally threaded clutch dental inlay 2 and tapped hollow sprocket wheel 3.With the size of externally threaded clutch dental inlay 2 and sprocket shaft 1 combination, in full accord with clutch dental inlay sprocket wheel, tapped hollow sprocket wheel 3 and is with sprocket deflection chain box center after externally threaded clutch dental inlay 2 assemblings.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
