As shown in Figure 1 and Figure 2, the clutch of the utility model Portable rice transplanter comprises road wheel 1, frame 4, sprocket wheel 5, clutch 6, axle 7, Compress Spring 8, seedling blocking plate 9, thrust ball bearing 10, end cap 11, screw rod 12, round nut 15, sleeve 16 and angular contact bearing 17, described frame 4 is rotated with respect to axle 7, and adopts intermittently and coordinate between frame 4 and axle 7; Road wheel 1 passes through screw rod 12 pretensions, and is located on axle 7 by thrust ball bearing 10, and seedling blocking plate 9 is fixed as one with frame 4; Between seedling blocking plate 9 and frame 4, seal by sealing ring 3.Described axle 7 is multidiameter, road wheel 1 by axle 7 by transmission of torque to clutch 6, described road wheel 1 is circumferentially fixed, is carried out axial restraint by nut 14, packing ring 13 and end cap 11 by flat key 2 on axle 7; Described clutch 6 is divided into left half-clutch and right semi-clutch, the angular contact bearing 17 of described left half-clutch is installed dorsad, and carry out pretension by round nut 15, described round nut 15 comprises round nut 15 and packing ring 13, the interior tongue of packing ring 13 inserts in the groove of axle 7, the outer tongue of packing ring 13 embeds in the groove of round nut 15, and nut is locked.The inside and outside circle of described angular contact bearing 17 is located at respectively by interference fits on the axle journal of axle 7 and in the endoporus of clutch 6; Right-hand member angular contact bearing carries out axial location by the axle collar and the right stage of clutch 6 endoporus, and left end angular contact bearing carries out axial location by sleeve 16 and the left stage of clutch 6 endoporus respectively.Axial location coordinates by the inner step of sleeve 16 and left half-clutch; Right semi-clutch adopts dive key 18 to carry out axial displacement; Described dive key 18 adopts screw to be fixed in the keyway of axle 7; One end of described Compress Spring 8 is located in the annular groove of right semi-clutch, and the other end is located in the annular groove of frame 4.
Sprocket wheel 5 adopts combined type mounting means, and gear ring is connected on the wheel hub of clutch with bolt.
In the utility model, described clutch, because torque is little, low speed combination, therefore adopt dog clutch, adopts trapezoidal tooth, intensity is high, can transmit larger torque, the wearing and tearing of energy auto-compensation tooth, described clutch adopts medium carbon steel surface hardening, hardness, at 48 ~ 54HRC, adopts the processes endoporus such as boring, car sky, adopts Milling Process tooth form, adopt shaping internal keyway, link and can adopt welding procedure or bolt to link with sprocket wheel; Described dive key adopts screw to be fixed in the keyway of axle, has been shaped with key screwed hole on key; Described spring is cylindroid helical-coil compression spring, adopts YI type, vertical with axis to ensure two supporting end faces, unlikely crooked when pressurized, ensures that clutch has good centering, and adopts carbon spring steel C level.According to this claim, clutch also comprises seizing wire, moves handle, and convenient manipulation controlled.
As shown in Figure 1, road wheel 1 by axle by transmission of torque to dog clutch 6, clutch 6 carries out Engage and disengage by axial linear slide, realize the transmission of motion, transmission of torque, to chain wheel driving mechanism, is passed to respectively to seedling-distributing mechanism 103, seedlings sending mechanism 102 and implanting mechanism 101 by sprocket wheel 5 by motion and torque.
As shown in Figure 2, axle is multidiameter, mainly bears moment of flexure and transmitting torque.The utility model is by road wheel transmitting torque M, and road wheel is circumferentially fixed on axle by flat key, and nut, packing ring and end cap carry out axial restraint.Frame needs certain rotation with respect to axle, adopts intermittently and coordinates.Because road wheel is by screw pre-tightening, bear unidirectional axial force, therefore adopt thrust ball bearing to install.The hole wall of clutch is thinner, cannot connect with key, and for for convenience detach, the installation of sprocket wheel adopts combined type, and gear ring is connected on clutch hub with bolt.Left half-clutch is taking bearing radial force as main, and the axial force of bearing is the part elastic force of Compress Spring on right semi-clutch, installs dorsad therefore adopt taking radial load as angular contact bearing main, unidirectional axial force.Adopt round nut to carry out pretension, axial location adopts the inner step of sleeve and left half-clutch.Right semi-clutch carries out axial displacement, if adopt spline, cost is high; Owing to being agricultural machinery, therefore adopt dive key.
Torque M is delivered to rotating shaft the right by road wheel, is delivered to right semi-clutch by dive key, when right semi-clutch moves right along axis, and tensioned, clutch separation; When right semi-clutch is moved to the left, spring relaxation, clutch engagement.Thereby torque M is passed to sprocket wheel by left half-clutch, by chain wheel driving mechanism, motion and power are passed to working portion.Because seedling blocking plate is fixed with respect to shelf position, adopt welding procedure that itself and frame are linked as to entirety.This arrangement works environment is severe, should adopt sealing ring waterproof, anti-mud, thereby ensures important spare part normal operation.
Area in vast rural area because of monolithic field is little, so be not suitable for carrying out farming with large-scale machinery.Add main equipment have that price is high, energy consumption is large, maintenance cost is large, move difficulty, to the high requirement of operator's technical requirement, make the mechanized planting of paddy rice have very large restriction.And this through use the Portable rice transplanter of the utility model clutch partition convenience, low price, be adapted to any soil property paddy field, simple to operate, easy to maintenance, operating efficiency is high, is a kind of miniature farm machinery product that really can enter each farmers' family.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
