Description
Technical field
The invention belongs to agricultural rotary tiller technical field, be specifically related to a kind of clutch for agricultural rotary tiller
Device.
Background technology
Clutch is the common components in machine driving, drive system can be separated at any time or engage.Agricultural
Rotary cultivator is the cultivation machinery completing to plough, harrow operation with tractor.Its by body, drive system with
And the rotary tillage work portion composition being connected with the clutch end of drive system.Rotary tillage work portion includes again rotary tillage
Cutter shaft, rotary tillage knife rest and be installed on the rotary blade on rotary tillage knife rest, by the high speed rotating of rotary blade,
Complete mechanization cuts soil, throwing soil operation.Specifically, drive train power output terminals A passes through spline mistake
Be full of coordinate realize with rotary ploughing cutter shaft couple drive it to rotate, as shown in Figure 6, clutch end A is all the time
Keep rigid water hammer transmission with rotary ploughing cutter shaft, and Rotary tillage blade has the feature of high-speed rotation, at rotary cultivator
When turning around or move backward, the most easily forget to close clutch, cause the rotation tooth of rotary cultivator to hang up operator's
Clothing or shoestring etc., easily hurt sb.'s feelings, and even jeopardizes the life of operator.Such as, rotary cultivator turning to or
When turning around, rotary cultivator clutch handle should be pushed separation point position, engage power under lifting state, wait to revolve
After cultivated machine reaches desired speed, unit can be started to walk, and is slowly fallen by rotary cultivator, makes rotary blade bury.
But rotary cultivator is when turning around or move backward, operator often forgets clutch is in released state, at a high speed
Under the ordering about of transfer motion power, the rotation tooth of rotary cultivator easily hangs up clothing or the shoestring etc. of operator, causes wound
People, and jeopardize the life of operator.It is therefore desirable to improve.
Summary of the invention
Present invention solves the technical problem that: a kind of clutch apparatus for agricultural rotary tiller is provided, use
Simple split-type structural improve solve under prior art because of the careless manipulations such as starting, gearshift cause rotation
Plough the technological deficiency that parts are damaged and facility safety is the highest.
The technical solution used in the present invention: for the clutch apparatus of agricultural rotary tiller, has as actively
The gear ring of parts and the step mandrel as passive components, the outer circumferential end face of described step mandrel in
Centrosymmetry is shaped with multiple waist type groove, the hinged waist type pin can upspring in waist type groove and reset in waist type groove；
The outer circumferential end face of step mandrel coordinates connection with the internal ring end clearance of gear ring, and gear ring slides and puts
Be placed on the step of step mandrel, the internal ring end face of gear ring be centrosymmetric be shaped with multiple both can block waist
Type pin can push back again the ear type groove of waist type pin.
One end of described waist type pin is hinged with the bottom surface of waist type groove by alignment pin, and the other end of waist type pin sets
Spring, described spring one end is had to be connected the medial wall of the other end and waist type pin movable end with the sidewall of waist type groove
Connect
Described waist type groove is two with gill type groove.
Described gear ring engages with the gearbox gear of rotary cultivator, and the axis hole of step mandrel is shaped with internal spline,
Described internal spline couples with the rotary ploughing cutter shaft external splines interference fit of rotary cultivator.
Present invention advantage compared with prior art:
Even if split-type structural also can cut off transmission, protection rotation in the case of clutch improper use immediately
The rotary tillage work portion of the machine of ploughing, is prevented effectively from the generation coupling the parts damage situation caused because direct transferring, simultaneously
There is again simple in construction, improve the feature of facility safety.

Detailed description of the invention
1-5 describes a kind of embodiment of the present invention below in conjunction with the accompanying drawings.
Tractor motive power output shaft passes through actuator drives, and rotary ploughing cutter shaft drives rotary tillage knife rest and rotary blade
Rotary blade on frame rotates and realizes rotary cultivator rotary tillage process.
For the clutch apparatus of agricultural rotary tiller, (as shown in Figure 3,4) has the tooth as driving part
Torus 1 and the step mandrel 2 as passive components, the outer circumferential end face of described step mandrel 2 is center pair
Claim to be shaped with multiple waist type groove 202, the adaptive waist type pin 3 of waist type groove 202, (as shown in Figure 4,5) waist type pin 3
One end by alignment pin 5 hinged with the bottom surface of waist type groove 202, the other end of waist type pin 3 is provided with spring 4,
Described spring 4 one end is connected the medial wall of the other end and waist type pin 3 movable end even with the sidewall of waist type groove 202
Connect.
(as shown in Figure 1, 2), the excircle matched in clearance of the step 201 of described step mandrel 2 is as master
The internal ring of the gear ring 1 of dynamic component, and gear ring 1 slide be positioned on the step 201 of step mandrel 2, tooth
The internal ring end face of torus 1 be centrosymmetric be shaped with multiple not only can block but also the ear type groove of waist type pin 3 can be pushed back
102, it is preferable that described waist type groove 202 is two with gill type groove 102, the outer shroud teeth of gear ring 1
101 engage with gearbox gear, and the axis hole of step mandrel 2 is shaped with internal spline 203, described internal spline 203 with
The rotary ploughing cutter shaft external splines interference fit of rotary cultivator couples.
The operation principle of the present invention:
(as shown in Figure 1), after step mandrel 2 and gear ring 1 matched in clearance, gear ring 1 is passed by change speed gear box
The power passed orders about generation and rotates counterclockwise, treats that the ear type groove 102 being shaped with on gear ring 1 forwards waist type pin 3 institute to
When position, waist type pin 3 is ejected and by ear type groove 102 block by the elastic force of the spring 4 compressed, now,
Step mandrel 2 and gear ring 1 are combined into one and are performed integrally Synchronous Transmission；And when gear ring 1 is transmitted by change speed gear box
Power drive turn clockwise, 3 groups of pressures of waist type pin are reset in waist type groove 202 by ear type groove 102,
Now, step mandrel 2 relatively rotates because of matched in clearance with gear ring 1, and clutch state changes from Fig. 1
For Fig. 2, even if forgetting clutch and drive system are in released state, power continues transmission, and with platform
The rotary ploughing cutter shaft that rank mandrel 2 interference fit couples can stop operating immediately with step mandrel 2, therefore,
Avoid the damage of rotary tillage workpiece generation rigidity, also safely provide guarantee for the person.
Above-described embodiment, simply presently preferred embodiments of the present invention, be not used for limiting the scope of the present invention,
Therefore all with content described in the claims in the present invention done equivalence change, all should be included in right of the present invention want
Within the scope of asking.
