Abstract
The invention discloses a safety clutch on a corn harvester. The safety clutch has the advantages of simple structure and convenient adjustment. The safety clutch does not produce severe vibration and noise. According to the safety clutch, coaxial round holes are arranged at the centers of a driving friction disc, a driven friction disc, a left flange and a right flange. The driving friction disc is fixed on the right side of the left flange. The driven friction disc matching the driving friction disc is fixed on the left side of the right flange. A convex ring on the driven friction disc is arranged on the right side of the driven friction disc. The convex ring is arranged in a flange hole of the right flange, and is rotatably connected with the right flange. The right flange is stopped by the driven friction disc arranged above and below the left side of the convex ring. The left and right flanges are connected through bolts. Compression springs are sleeved on the bolts on the right side of the right flange. Adjusting nuts are arranged on the bolts on the right side of the compression springs. With the safety clutch, an ear-picking mechanism can be effectively protected, and severe vibration and noise are prevented during working.

Summary of the invention
Present invention solves the technical problem that and be to provide a kind of simple in construction, easy to adjust, the overload-release clutch that will not produce on the maize harvesting machine of strong vibration and sound.
The technical scheme is that and so complete, overload-release clutch on maize harvesting machine, include active friction disk, driven friction disk, left flange plate and right ring flange, active friction disk, driven friction disk, the centre of left flange plate and right ring flange is provided with the circular hole in same axle center, described active friction disk is fixed on the right side of left flange plate, the driven friction disk matched with active friction disk is fixed on the left of right ring flange, bulge loop on driven friction disk is located at the right side of driven friction disk, bulge loop is located at the flange hole on right ring flange Nei and is rotationally connected with right ring flange, right ring flange is arranged on the driven friction disk of upper and lower on the left of bulge loop and blocks, left, right ring flange is bolted together, it is located on the bolt on the right side of right ring flange and is cased with stage clip, it is located at the bolt on the right side of stage clip and is provided with regulating nut.
Also including sprocket wheel, described sprocket wheel is fixing with active friction disk to be connected, and the axle center of active friction disk is identical with the axle center of the sprocket hole of sprocket wheel.
The solution have the advantages that; clutch safety owing to being matched with stage clip by existing ratchet transform the clutch safety matched with stage clip by frictional disk as; the concavo-convex friction of prior art is changed into face and the face friction of the present invention; the frictional force between left and right frictional disk can be adjusted easily, it is possible to effectively protect corn snapping unit.During work, strong vibration and sound will not be produced.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment one: active friction disk 14, driven friction disk 13, the circular hole in same axle center it is provided with in the middle of left flange plate 7 and right ring flange 9, described active friction disk 14 is fixed on the right side of left flange plate 7, the driven friction disk 13 matched with active friction disk 14 is fixed on the left of right ring flange 9, bulge loop 12 on driven friction disk 13 is located on the right side of driven friction disk 13, bulge loop 12 is located in the flange hole 15 on right ring flange 9 and is rotationally connected with right ring flange 9, right ring flange 9 is arranged on the driven friction disk 13 of upper and lower on the left of bulge loop 12 and blocks, left flange plate 7, right ring flange 9 is linked together by bolt 8, it is located on the bolt 8 on the right side of right ring flange 9 and is cased with stage clip 10, it is located at the bolt 8 on the right side of stage clip 10 and is provided with regulating nut 11.
Embodiment two: on the basis of embodiment one, also includes sprocket wheel 1, and described sprocket wheel 1 is fixing with active friction disk 14 to be connected, and the axle center of active friction disk 14 is identical with the axle center in the chain hole of sprocket wheel 1.
When the present invention is installed, sprocket wheel 1, active friction disk 14, driven friction disk 13, left flange plate 7 and right ring flange 9 are located at power transmission shaft one end, sprocket wheel 1, active friction disk 14, left flange plate 7 and right ring flange 9 are connected with drive axis, and driven friction disk 13 is fixing with power transmission shaft 6 to be connected.For preventing bulge loop 12 displacement laterally in rotation, the power transmission shaft outside bulge loop is spirally connected hold-doun nut 5.
When work often works, active friction disk 7 and driven friction disk 9 compress mutually, and the frictional force produced between the two meets the normal kinetic demand of power transmission shaft or sprocket wheel.When power transmission shaft 6 is power output shaft, when sprocket wheel 1 is power input wheel, when power transmission shaft 6 transships excessive, the frictional force produced between active and passive frictional disk is less than after the power demand required for power transmission shaft 6, sprocket wheel 1, left flange plate 7, active friction disk 14, right ring flange 9 rotate, and driven friction disk 13 and then power transmission shaft 6 stops operating together.When power transmission shaft 6 is power input shaft, when sprocket wheel 1 is power output wheel, when sprocket wheel 1 transships excessive, the frictional force produced between active and passive frictional disk is less than after the power demand required for sprocket wheel 1, sprocket wheel 1, left flange plate 7, active friction disk 14, right ring flange 9 stop operating, and driven friction disk 13 and then power transmission shaft 6 rotates together.Thus can effectively prevent because damaging power transmission shaft or sprocket wheel and the relevant apparatus of this power transmission shaft or chain wheel drive when power transmission shaft or sprocket wheel transship excessive.
When this clutch is arranged on harvesting device power output shaft, power transmission shaft 6 gathers in device power output shaft exactly, sprocket wheel 1 is power input wheel, sprocket wheel 1 imparts power to harvesting device power output shaft by active and passive frictional disk, thered is provided power to harvesting device by harvesting device power output shaft again, when the overload gathering in device is excessive, harvesting device quits work because not having enough power, just can effectively prevent the damage of harvesting device.When this clutch is arranged on corn snapping unit power input shaft, power transmission shaft 6 is corn snapping unit power input shaft, sprocket wheel 1 is corn snapping unit power output wheel, corn snapping unit power input shaft imparts power to sprocket wheel 1 by active and passive frictional disk, power is provided to corn snapping unit again by sprocket wheel 1, when the overload of corn snapping unit is excessive, corn snapping unit quits work because not having enough power, just can have the damage preventing corn snapping unit.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, also should be regarded as protection scope of the present invention.
