Description

  The present invention relates to a compaction machine, and more particularly to a dustproof net technology for protecting a heat exchanger.

A heat exchanger such as a radiator is provided in front of an internal combustion engine mounted on a compaction machine.
This heat exchanger is a device that heats and cools cooling water or the like that becomes hot when the internal combustion engine is driven, and cools the fins because it is provided with a plurality of fins and blades. There is a problem in that the blade is hit with sand dust or small stones and is deteriorated due to clogging or deformation.

Therefore, a filter (dustproof net) is installed on the front side of the heat exchanger to prevent the heat exchanger from being exposed to dust or the like.
However, if a compaction machine is used without cleaning the filter for a long time, there is a problem that the filter exposed to sand dust or the like will be clogged.

As described above, it is not preferable that the filter is clogged because it makes it difficult for the outside air to be sent to the heat exchanger.
In this case, it is conceivable to make the filter removable and wash it regularly.
Further, a method has been developed in which a guide is provided on the machine body to facilitate the attachment and detachment of the filter, and a plurality of filters can be attached along the guide (Patent Document 1).

However, as described above, in order to make the filter removable, a space for removing the filter is required, but the compaction machine is important for visibility from the operator and turning performance at the time of turning. Therefore, it is necessary to shorten the entire length of the machine body, and it is not preferable to provide a wide space for attaching and detaching the filter.
Further, in the technique disclosed in Patent Document 1, a plurality of filters are screwed together, and it is necessary to traverse around the machine body to the left and right in order to remove all the screws from the filters. There's a problem. Further, in each filter, when a part such as an exhaust pipe is arranged around the screw screwing the filter, there is a problem that it is difficult for an operator's hand and a tool for removing the screw to enter. is there.

  The present invention has been made in view of such problems, and an object thereof is to improve workability for attaching and detaching the dustproof net, and further to provide a dustproof net provided in a portion where a working gap is narrow. Even if it is, there exists in providing the compaction machine which can be made removable easily.

In order to achieve the above object, a compaction machine of the present invention includes a heat exchanger that circulates a heat source to cool a high-temperature medium that becomes high in temperature, and a heat exchanger that is disposed in front of the heat exchanger. A first net for protecting the heat exchanger from dust and a first net for protecting the heat exchanger from dust and covering the heat exchanger in parallel adjacent to the first net and in front of the heat exchanger; An installation member provided in front of the heat exchanger, on which the first net and the second net are installed, and an end portion of the second net on the side of the first net, when the net and the second net is installed in the installation member, and a regulating portion for regulating the movement in the direction away from the installing member of the first net, the first net and The second nets are arranged in parallel in the left-right direction, and A lower end of the first net and the second net, an end of the first net opposite to the second net, and an end of the second net on the first net side.

The support member 52r2 guides and supports the right end of the radiator net 44 to a predetermined installation position, and the upper end of the radiator net 44 is screwed and fixed to the frame 50 by the thumbscrew 56.

  Therefore, as in the case of installing the oil cooler net 42 and the radiator net 44 from above, for example, the lower ends of the oil cooler net 42 and the radiator net 44, which are difficult to reach, can be easily installed at a predetermined installation position by a work from above. Even if, for example, parts such as the exhaust pipe 20 and the exhaust pipe cover 22 are disposed near the upper portion of the oil cooler net 42 and work cannot be performed from the right side of the tire roller 1, the oil cooler net 42 and The right end of the radiator net 44 can be easily installed at a predetermined installation position from the left side of the tire roller 1, and by fixing the upper end of the radiator net 44 to the frame 50 with the thumbscrew 56, the regulation is performed. The member 54 favorably restricts the movement of the oil cooler net 42 in the direction away from the frame 50. It can be.

Of the support members 52, the support member 52r2 that supports the radiator net 44 is provided above the upper end of the oil cooler net 42.
Therefore, since the support member 52r2 that supports the radiator net 44 is provided on the frame 50 above the upper end of the oil cooler net 42, the oil cooler net 42 and the radiator net 44 are supported when the oil cooler net 42 is installed. The oil cooler net 42 and the radiator net 44 can be installed side by side without interfering with the support member 52r2.

The description of the compaction machine according to the present invention has been finished above, but the present invention is not limited to the above-described embodiment, and can be modified within a range not departing from the gist of the invention.

In this case, all the nets other than the leftmost net may be provided with restricting members similar to the restricting members 54 provided on the radiator net 44 so as to extend toward the adjacent nets.

In addition, in the present embodiment, the support member 52 is used to guide and support the oil cooler net 42 and the radiator net 44 at a predetermined installation position, but the support member is guided to a predetermined installation position and supported. As long as it can be done, it does not have to have the shape like the support member 52.
Further, in the present embodiment, the restriction member 54 is used to suppress the movement of the oil cooler net 42 in the direction away from the frame 50, but the restriction member moves in the direction in which the oil cooler net 42 separates from the frame 50. As long as it is possible to suppress the movement, it is not necessary to have the shape like the regulation member 54.
