Problems solved by technology

[0003] The knotter sprocket is an important part of the baler. Most of the existing knotter sprockets are connected to a support shaft through bearings. The sprocket can rotate around the support shaft. After long-term use, the air dust is easy Entering the inside of the bearing, the rotation of the bearing is limited, which in turn affects the normal rotation of the sprocket. Therefore, it is often necessary to add lubricating oil to the bearing manually on a regular basis, which is cumbersome and inconvenient to operate.

Embodiment 1

[0025] see Figure 1-3 , this embodiment provides a sprocket lubrication-free mechanism for a knotter, including a support shaft 1 and a sprocket 7 that is rotated on the support shaft 1 through two sets of bearings 5, and the two sets of bearings 5 ​​are far away from each other One side is provided with a limit assembly, and the inside of the sprocket 7 is provided with an oil inlet channel 8 connected between the two groups of bearings 5, and the outside of the support shaft 1 is also fixed with an oil storage tank 12, and the oil storage tank 12 There are two groups of piston plates 18 movable inside, and the sides of the two groups of piston plates 18 away from each other are fixedly provided with a connecting rod 17, and the connecting rod 17 extends to the outside of the oil storage tank 12 and is fixedly connected with a pressure rod 13, The side of the pressure rod 13 away from the connecting rod 17 is provided with a second magnetic sheet 15, the pressure rod 13 is c...

Embodiment 2

[0034] see figure 1 , a lubrication-free mechanism for the sprocket of a knotter. Compared with Embodiment 1, in this embodiment, two sets of retaining rings 6 are fixedly arranged on the outside of the support shaft 1, and the retaining rings 6 abut against two sets of bearings 5 The inner ring on the opposite side prevents the outer ring of the bearing 5 from contacting the retaining ring 6 when rotating, thereby affecting the normal rotation of the outer ring of the bearing 5 and preventing the outer ring of the bearing 5 from wearing and tearing.

[0035]In the embodiment of the present invention, through the cooperation of the first magnetic sheet 14 and the second magnetic sheet 15, the lubricating oil inside the oil storage tank 12 can be continuously supplied to the area between the two sets of bearings 5, and the two sets of bearings 5 It continuously flows back to the inside of the oil storage tank 12 to form a circulation circuit of lubricating oil. While providing ...

Abstract

The invention provides a knotter chain wheel lubrication-free mechanism, and belongs to the technical field of bundling machines. The knotter chain wheel lubrication-free mechanism comprises a support shaft and a chain wheel rotationally arranged on the support shaft through two bearings, wherein limiting assemblies are arranged on the sides, away from each other, of the two bearings, an oil inlet channel communicating to the position between the two bearings is arranged inside the chain wheel, an oil storage tank is further fixedly arranged outside the supporting shaft, and two piston plates are movably arranged inside the oil storage tank. In the embodiment of the invention, through the cooperation of a first magnetic sheet and a second magnetic sheet, and lubricating oil inside the oil storage tank can be continuously supplied to an area between the two bearings and continuously flows back into the oil storage tank from the two bearings, so that a lubricating oil circulation loop is formed, friction heat is further taken away when the bearings rotate while the lubricating oil is supplied to the bearings, the heat dissipation of the bearings is achieved, compared with the prior art, the knotter chain wheel lubrication-free mechanism has the advantages of being simple in structure, convenient to use and convenient to lubricate.

Description

technical field [0001] The invention belongs to the technical field of tying machines, in particular to a lubrication-free mechanism for sprocket wheels of a knotter. Background technique [0002] my country is a large agricultural country. Farmers leave a lot of straw after harvesting corn, wheat and other crops. Most areas use incineration, which seriously wastes resources and causes environmental pollution. The square baler is a commonly used straw and forage harvesting machine. It is mainly used to harvest scattered and standing straw and forage, and use ropes to tie the straw and forage into square bundles, which is convenient for transportation and redevelopment. [0003] The knotter sprocket is an important part of the baler. Most of the existing knotter sprockets are connected to a support shaft through bearings. The sprocket can rotate around the support shaft. After long-term use, the air dust is easy Entering the inside of the bearing, the rotation of the bearing...
