Abstract
A traction device of a multipurpose farmland operation machine comprises a traction box, a traction shaft, a traction main pin, a plane bearing and a copper bush. The traction box is fixed on a rear cross beam of a front carfrarme of the farmland operation machine, and the rear end of the traction shaft is connected with a traction sleeve on the front cross beam of the rear carframe of the farmland operation machine. The front end of the traction shaft is connected with the traction box through the traction main pin and a fixing piece, and the plane bearing is arranged on the lower end face, contacted with the traction box, of the traction shaft. The copper bush is arranged on the traction main pin. The traction device can prevent abrasion of the traction box and abrasion and deformation of the main pin.
Description
Technical field
The utility model relates to a kind ofly many use farm land cultivator, especially relates to a kind of draw-gear of many usefulness farm land cultivators.
Background technology
Existing farm land cultivator is mainly the formula of bowing and turns to, and the defective that its draw-gear exists is: traction box directly contacts with the lower surface of axis of traction, and traction box is worn and torn easily; Stub directly contacts with axis of traction, easy to wear, the distortion of stub.
The utility model content
Technical problem to be solved in the utility model is that a kind of many draw-gears with farm land cultivator of avoiding traction box wearing and tearing and stub to wear and tear, be out of shape are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of many draw-gears with farm land cultivator, comprise traction box, axis of traction, traction stub, plane bearing and copper sheathing, described traction box is fixed on the rear cross beam of farm land cultivator front frame, traction casing behind the rear end of described axis of traction and the farm land cultivator on the front beam of vehicle frame links to each other, the front end of described axis of traction links to each other with traction box by traction stub and fixture, described plane bearing is installed on axis of traction and place, the contacted lower surface of traction box, and described copper sheathing is installed on the traction stub.
Further, be respectively equipped with pad between described traction box and axis of traction, the plane bearing.
Further, described fixture comprises slotted nut, split pin, and described split pin is passed the traction stub and is fixed on the slotted nut.
Compared with prior art, the utlity model has following advantage: by plane bearing is set, can guarantee relatively rotating of axis of traction and traction box, fretting wear when also preventing from relatively rotating simultaneously, turn to light, steadily safety has damping recoil effect to a certain degree, can change the trafficability characteristic of car load well; By copper sheathing is set, can avoid axis of traction directly to contact with stub, thereby significantly reduce wearing and tearing, the distortion of stub, even copper sheathing damages and changes, cost is also much lower; Further, the design of slotted nut, split pin, safety is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises traction box 1, axis of traction 2, traction stub 3, plane bearing 4 and copper sheathing (not shown), described traction box 1 is by on the rear cross beam that is bolted to the farm land cultivator front frame, traction casing behind the rear end of described axis of traction 2 and the farm land cultivator on the front beam of vehicle frame links to each other, the front end of described axis of traction 2 is by traction stub 3 and slotted nut, split pin links to each other with traction box 1, wherein split pin is passed traction stub 3 and is fixed on the slotted nut, described plane bearing 4 is installed on axis of traction 2 and place, traction box 1 contacted lower surface, and described copper sheathing is installed on the traction stub 3.
Be respectively equipped with pad between described traction box 1 and axis of traction 2, the plane bearing 4.
Present embodiment can guarantee relatively rotating of axis of traction and traction box, and the fretting wear when simultaneously also preventing from relatively rotating turns to lightly, and steadily safety has damping recoil effect to a certain degree, can change the trafficability characteristic of car load well; Can avoid axis of traction directly to contact with stub, thereby significantly reduce wearing and tearing, the distortion of stub, even copper sheathing damages and changes, cost is also much lower; Safe.
Claims (3)
1. use the draw-gear of farm land cultivator one kind more, comprise traction box, axis of traction, traction stub, described traction box is fixed on the rear cross beam of farm land cultivator front frame, traction casing behind the rear end of described axis of traction and the farm land cultivator on the front beam of vehicle frame links to each other, the front end of described axis of traction links to each other with traction box by traction stub and fixture, it is characterized in that: also be provided with plane bearing and copper sheathing, described plane bearing is installed on axis of traction and place, the contacted lower surface of traction box, and described copper sheathing is installed on the traction stub.
