Description

  The present invention relates to a front work tool of a snow removal work machine.

A snow removal work machine represented by a wheel loader, a tractor, etc. is equipped with a blade or bucket front work clothes in front of a traveling body as a vehicle body, and removes snow with the front work tool (the blade is removed). (See Japanese Patent Application Laid-Open No. 2003-13419).
JP2003-13419 (FIG. 1)

  However, if snow gets on the surface of the front work tool, the snow further adheres on the snow, and the weight of the front work tool becomes heavy, and the work efficiency deteriorates. For example, in the case of a blade plate, snow accumulates in the front and the efficiency of scraping snow deteriorates. In the case of a bucket, the weight of the bucket increases, the operation becomes slow, and the carrying capacity decreases. Of course, since the weight increases, the fuel consumption also deteriorates.

  The present invention has been devised in view of the above-described problems of the prior art, and aims to provide a technique capable of preventing deterioration of work efficiency due to snow on the front work implement.

  For this reason, the front work tool of the snow removal working machine according to the present invention is characterized in that the work surface is covered with a material having a low friction coefficient.

  Here, the work surface of the front work tool refers to a surface that comes into contact with snow when performing snow removal work. For example, if the work tool is a blade, it refers to the front surface of the blade, and if it is a bucket, it refers to the inner surface. However, it goes without saying that the structure other than that surface may be the same. The material having a low friction coefficient is, for example, fluorine.

  In the present invention, since the work surface of the front work tool is covered with a material having a low coefficient of friction, even if snow touches the work surface during snow removal work, the sticking of snow is extremely reduced.

  Furthermore, you may arrange | position a heating member in the arbitrary locations of a front work tool. There are various modes of arrangement, such as embedding under the work surface of the work tool or contacting the back of the work surface. In either case, the front work tool itself is heated. Thus, snow on the work surface can be more effectively prevented. As the heating member, in addition to the heating wire shown in the embodiments described later, a hot water flow channel, a hot oil flow channel, and the like for flowing the temperature adjustment medium are conceivable. In the case of a hot water flow path or a hot oil flow path, a dedicated temperature adjustment medium may flow there, but as the medium, hydraulic oil that becomes high temperature due to various operations of the vehicle, high temperature cooling water after engine cooling, etc. are used. For example, existing media can be used effectively and cost is beneficial.

  Since this invention reduces the amount of snow on the front work implement, there has been a problem in the past, such as snow accumulation and the efficiency of snow removal work worsening, and further, the weight increases and fuel consumption worsens. Greatly improved.

  A specific embodiment of the present invention will be described with reference to the drawings. In addition, it is natural that the present invention is not limited to the following embodiments, including vehicles and work tools to be applied.

  This embodiment is an example applied to a snow loader wheel loader as shown in FIG. This snow removal wheel loader is provided with a bucket 1 as a front work tool in front of it. The bucket 1 scoops and transports snow to perform snow removal.

  The bucket 1 is formed of a metal plate (metal plate layer 4), but the inner side surface 2 serving as a work surface is covered with fluorine as shown in FIG. ). The covering material may be another material as long as it has a low friction coefficient. Further, a heating wire 5 as a heating member is embedded on the upper surface side of the metal plate. The heating wire 5 is controlled so that a current flows when a predetermined weight is detected on the metal surface by a weight detection sensor (not shown). Instead of the heating wire 5 that is a heating member, the hydraulic piping or the engine cooling water piping may be extended and the extended portion may be disposed at the place, and further, the extended piping may be connected to the back side of the work surface. It is good also as a form contact | abutted to another location. The hydraulic oil and engine cooling water are hot, and if they are circulated into the bucket 1, not only the same effect as the heating wire 5 can be obtained, but also the existing medium can be used effectively, and the cost is also increased. There is an advantage that it can be cheap.

  The bucket 1 of the present embodiment is configured as described above, and the inner side surface 2 is covered with fluorine, so the friction coefficient is extremely low, and snow hardly sticks to the surface. Even if it sticks depending on the snow quality, if it sticks more than a predetermined weight, current flows through the heating wire 5 in the metal plate and the temperature of the inner surface 2 rises, so that the snow can be melted immediately. As a result, no snow accumulates in the bucket 1 (inside surface 2) during snow removal work, and all the problems of increased weight due to snow, resulting in reduced snow removal work efficiency, and even fuel efficiency are all solved. Become.

  The present invention is applicable to any snow removal vehicle including a front work tool.
