The utility model content
The purpose of this utility model is for the problems referred to above that exist, and the rice transplanter vertical seedlings sending single direction ratchet that a kind of seedling sending accuracy is high, easy to adjust, structure is more exquisite stopping means is provided.
For achieving the above object, the utility model adopts following technical proposals: rice transplanter vertical seedlings sending single direction ratchet stopping means of the present utility model, comprise holder, seedling case driving shaft, swing arm, also comprise cam, reduction torsion spring, adapter sleeve, unilateral bearing, steel ball, adapter sleeve is contained on the seedling case driving shaft by the unilateral bearing splicing sleeve, be positioned on the cross section, center of this adapter sleeve, this adapter sleeve external peripheral surface is provided with four outer grooves successively, the driving sliding sleeve of cam is sleeved on the outside of adapter sleeve rotationally, corresponding with four outer grooves of this adapter sleeve, radially be provided with four cylindrical holes on the driving sliding sleeve of this cam, each cylindrical hole consists of respectively a cylindrical cavity with corresponding outer groove, respectively be provided with a steel ball in four cylindrical cavities, the driving sliding sleeve rotatably support of this cam is sleeved in the holder, be on the same cross section with described four cylindrical holes, this holder inner surface is along circumferentially being laid with three inner groovies, the arranged outside reduction torsion spring of this holder, this reduction torsion spring one end is installed on the flange of holder, and the other end is installed on the cam.
As preferred version of the present utility model, described holder inner surface is identical with four outer groove groove depths that this adapter sleeve external peripheral surface is provided with successively along three inner groovies that circumferentially are laid with.
After adopting technique scheme, the beneficial effect that the rice transplanter vertical seedlings sending single direction ratchet stopping means that the utility model provides has is:
The power of the present utility model casing of planting from the centre of rice transplanter spreads out of, drive swing arm via connecting rod and be delivered to seedling case cam position, make cam angle swinging on request, the driving sliding sleeve of cam will drive adapter sleeve by steel ball and drive angle of seedling case driving shaft rotation, seedling case driving shaft drives seedling case roller and rotates, thereby realization vertical seedlings sending, when the power angle that the casing of planting in the centre spreads out of seedling case cam exceeds preset angles, cam is rotated further, steel ball is subject to centrifugal action, in cylindrical cavity, enter in certain inner groovy of this holder inner surface, this moment, driving sliding sleeve and the steel ball of cam were in the idle stroke state, and power disconnects, and seedling case roller corner is constant, thereby realize that vertical seedlings sending apart from uniformity, satisfies accurate vertical seedlings sending requirement.The utility model compact conformation, volume are little, lightweight, and cam initial angle capable of regulating, guarantee that seedling sending is more accurate.Therefore, obtained the effect that the seedling sending accuracy is high, easy to adjust, structure is more exquisite.
