Description
Technical field
The utility model belongs to agricultural machinery technological field, specifically, relates to a kind of automatic clutch of agriculture microtilling machine.
Background technique
At present, generally be to adopt belt tension clutch or mechanical clutch mode to realize disconnection between the driving and driven mechanism on the coaxial line or combination on the agriculture microtilling machine.In belt tension clutch mode, make belt compress driving and driven belt pulley by the external operating mechanism of manual control, power is delivered on the driven pulley from drive pulley, further is delivered on the rotary tillage facility by gear again, realizes ploughing operation.The adjustment of belt tension clutch mode operating mechanism in operation process is complicated, belt serious wear and easy-rupturing, poor reliability, and clutch separates not thorough, thereby causes microtilling machine gearshift difficulty easily, and therefore the gear internal gear damages easily.Mostly adopt wet friction slice clutch structure in the mechanical clutch mode, need manual operations during use, inconvenient operation, and complex structure, the manufacture cost height, the life-span is short, and the moment of torsion of transmission is little.In recent years, also have on microtilling machine and to use the shoe block type automatic centrifugal clutch, its power input is to be delivered on the hoof piece by belt pulley, connecting sleeve and hoof piece positioning disk, power output then is to be delivered to transmission shaft by the clutch case, output and input are in the same way, owing to there is the input belt pulley, therefore still there are complex structure, problem that transmitting torque is little.
The model utility content
Problem to be solved in the utility model provides that a kind of simple in structure, transmitting torque is big, the agriculture microtilling machine automatic clutch of reliable operation.
For solving the problems of the technologies described above, the agriculture microtilling machine automatic clutch of this utility model, have case and be positioned at the hoof piece of case, on the hoof piece face relative, be provided with friction plate with the case madial wall, plural hoof piece is between circumferential array and the adjacent two hoof pieces and is connected with spring, and an end of hoof piece is positioned on the driving disc with bearing pin, is provided with internal spline in the journal hole of driving disc, the outside of case is equipped with land by rivet, is provided with internal spline in the journal hole of land.
During use, the inner splined hole on the driving disc directly links to each other with the output shaft of power equipments such as petrol engine or diesel engine, and the land that links to each other with case then directly links to each other with the axle of gearbox input shaft or rotary tillage facility.Power is delivered on the hoof block assembly by driving disc earlier, the hoof block assembly rotates with driving disc, raising along with rotating speed, the pulling force that the hoof piece overcomes spring under action of centrifugal force outwards gets rid of, friction plate on the hoof piece is contacted with the case madial wall, the hoof piece drives case and rotates together under the effect of frictional force, realize in conjunction with and with transmission of power to land.When speed reduced, the centrifugal force that the hoof piece is subjected to can reduce microtilling machine in operation process, and when less than the pulling force of spring, friction plate on the hoof piece and case madial wall disengage, and then clutch is realized separating.
The automatic centrifugal clutch that uses on the utility model and the existing microtilling machine is compared, and structure is simplified, and transmission of power is more direct, and the moment of torsion of transmission is bigger, and it is more reliable to work.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the arrangement states schematic representation that hoof piece 2 is making progress in week in the utility model.
Embodiment
As shown in Figure 1 and Figure 2, agriculture microtilling machine automatic clutch of the present utility model, have case 1 and be positioned at the hoof piece 2 of case 1, on hoof piece 2 face relative, be provided with friction plate 3 with case 1 madial wall, three hoof pieces 2 are between circumferentially evenly distributed and the adjacent two hoof pieces 2 and are connected with spring 4, one end of hoof piece 2 is positioned on the driving disc 6 with bearing pin 5, be provided with internal spline 6a in the journal hole of driving disc 6, the outside of case 1 is equipped with land 7 by rivet 8, is provided with internal spline 7a in the journal hole of land 7.
During assembling, the inner splined hole 6a on the driving disc 6 directly links to each other with the output shaft of power equipments such as petrol engine or diesel engine, and 7 of the lands that links to each other with case 1 directly link to each other with the axle of gearbox input shaft or rotary tillage facility.Power is delivered on hoof piece 2 assemblies by driving disc 6 earlier, hoof piece 2 assemblies are with driving disc 6 rotations, raising along with rotating speed, the pulling force that hoof piece 2 overcomes spring 4 under action of centrifugal force outwards gets rid of, friction plate 3 on the hoof piece 2 is contacted with case 1 madial wall, hoof piece 2 drives cases 1 and rotate together under the effect of frictional force, realize combination and with transmission of power to land 7.When speed reduced, the centrifugal force that hoof piece 2 is subjected to can reduce microtilling machine in operation process, and when less than the pulling force of spring 4, the friction plate 3 on the hoof piece 2 disengages with case 1 madial wall, and then clutch is realized separating.
Claims (2)
1, a kind of agriculture microtilling machine automatic clutch, comprise case (1) and be positioned at the hoof piece (2) of case (1), on hoof piece (2) face relative, be provided with friction plate (3) with case (1) madial wall, plural hoof piece (2) is between circumferential array and the adjacent two hoof pieces (2) and is connected with spring (4), it is characterized in that: an end of described hoof piece (2) is positioned on the driving disc (6) with bearing pin (5), be provided with internal spline (6a) in the journal hole of driving disc (6), the outside of case (1) is equipped with land (7) by rivet (8), is provided with internal spline (7a) in the journal hole of land (7).
2, agriculture microtilling machine automatic clutch according to claim 1 is characterized in that: described hoof piece (2) upwards is being evenly equipped with three week.
