In order to suppress the intrusion and adhesion of mud with such a seal structure, it is necessary to provide an expensive seal having a high sealing function and to increase the seal pressure on the wheel shaft or wheel case of the seal.
However, an expensive seal causes an increase in manufacturing cost, and if it is provided in a state in which the seal pressure is increased, there is a possibility that the wear of the wheel shaft and the wheel case may be accelerated, and there is room for improvement in terms of extending the life of the equipment.
In addition, if a rotating wheel such as a traveling wheel is likely to adhere mud, it can be dropped onto the field surface in the middle of rotating and lifting the lump that has been lifted by the rotating body. is there. If it does so, there exists a possibility that a soil block may fall on a planting surface and it cannot avoid pushing down adjacent seedlings.

  An object of the present invention is to provide an agricultural machine capable of reducing the conventional adverse effects as much as possible by applying an effective coating agent to the components of the work machine on which mud adhesion is assumed.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is a dry coating agent in which a solid lubricant mainly composed of PTFE is dispersed in a binder resin and mixed with a solvent in a component of a work machine on which mud adhesion is assumed. The effect is as follows in that the coated surface is formed.

[Action]
Since the dry-coating surface is formed on the component parts, the solid lubricant mainly composed of PTFE on the dry-coating surface exerts its function and suppresses the mud adhesion even if mud mud adheres to the component parts. To do. Therefore, it is possible to avoid a situation in which the attached mud becomes a lump and the lump falls on the field as in the prior art.
On the other hand, since the solid lubricant causes a reduction in frictional force, it is possible to increase the sealing pressure, thereby preventing intrusion of mud and avoiding wear of components.

〔effect〕
In this way, the adverse effects caused by mud deposits can be achieved by making simple modifications to form the dry-coating surface without any mechanical changes, and the life of the equipment can be extended and planted. It was possible to suppress the situation where workability such as work was reduced.

[Function and effect]
Since the dry coat treatment surface is applied to at least one of the wheel shaft and the sealing material, the frictional resistance between the wheel shaft and the sealing material can be reduced. Thereby, the sealing pressure to the wheel shaft and the wheel case of the sealing material can be increased, and intrusion of mud can be suppressed. In addition, wear of the seal material or the wheel shaft can be prevented in advance.
