Description

  The present invention relates to a technique for easily refilling a fuel tank of a snowplow with fuel.

Since snow plows are used in cold regions, consideration must be given to freezing. For example, a technique for accommodating an engine and a fuel tank in an engine room is known (for example, see Patent Document 1).
JP-A-57-74414 (FIG. 1-2)

Patent Document 1 will be described with reference to the following figure.
FIG. 6 is a schematic diagram of a conventional snow blower. The conventional snow blower 200 is an auger type snow blower in which an engine room 203 is provided behind an auger housing 202 having an auger 201 and an engine 204 and a fuel tank (not shown) are stored in the engine room 203. The engine room 203 includes a rear wall 202a of the auger housing 202, a lower shroud 205 provided at a lower rear portion of the rear wall 202a, and an upper shroud 206 provided at an upper portion of the lower shroud 205. The fuel filler port 207 of the fuel tank extends upward through the upper shroud 206, and its upper end is closed by a cap 208.

  By pushing the push handle 211 behind the engine room 203, the snow can be removed by the auger 201 while turning the wheels 212 to move the snow remover 200 forward. The fuel can be supplied to the fuel tank by putting the fuel through the exposed lubrication port 207. Reference numeral 213 denotes a vane, 214 denotes a V-belt, 215 denotes an exhaust pipe for an engine, and 216 denotes a cap for an oil inlet of an oil tank.

Since the fuel tank is housed in the engine room 203, it is a measure against freezing of the fuel tank. However, the fuel port 207 and the cap 208 of the fuel tank remain exposed. If the connection between the lubrication port 207 and the cap 208 is frozen, the fuel supply operation is troublesome.
Furthermore, in order to replenish the fuel tank particularly in a small snowplow, it is common to put the fuel into the lubrication port 207 from a fuel supply container called a plastic container having a small capacity (about 18 liters). In this case, in order to obtain a drop from the fuel supply container to the lubrication port 207, the fuel is supplied while the fuel supply container is lifted or placed on a table. In this case, the fuel supply operation is troublesome. Further, there is room for improvement in reducing the burden on the worker.

  It is an object of the present invention to provide a technique capable of easily replenishing a fuel tank of a snowplow with fuel and reducing a burden on an operator.

In particular, since the heat generated by the engine housed in the engine room can be effectively used, freezing of the fuel tank and the fuel supply port can be sufficiently prevented. Moreover, only when supplying the fuel, the upper cover may be opened to expose the fuel supply port. Since the fuel supply port does not freeze, the cap can be easily removed and the fuel can be supplied promptly. As a result, fuel can be easily refilled into the fuel tank, and the burden on the operator can be reduced.

  Further, in the invention according to claim 1, the mounting table is usually stored in the engine room, and only when supplying fuel, the upper cover is opened and the mounting table is swung to the horizontal position. Can be placed. Since the mounting table is near the fuel supply port, it is easy to supply the fuel from the fuel supply container to the fuel supply port. In addition, the head from the fuel supply container mounted on the mounting table to the fuel supply port is sufficient, and it is not necessary to lift the fuel supply container or mount the fuel supply container on the table when injecting. Therefore, fuel can be supplied promptly. As a result, fuel can be easily refilled into the fuel tank, and the burden on the operator can be reduced.

  In the invention according to claim 2, since the horizontal position of the mounting table is set to the left side or the right side of the engine room, fuel can be replenished from the side of the snow blower. Since the distance from the worker to the fuel supply port is short, replenishment workability is improved.

You can get closer. Injection of fuel from the fuel supply container mounted on the mounting table becomes easier. Moreover, even though the mounting table is brought close to the fuel supply port, the mounting table straddles the fuel supply port when the mounting table is swung, so that the mounting table does not hit the fuel supply port. Furthermore, since the dimension from the swing base end to the swing tip of the mounting table can be reduced, the storage capacity in the engine room is improved.

  In the invention according to claim 4, since the mounting table is further mounted on the mounting member for detachably mounting the fuel tank on the body, the mounting table can be mounted simultaneously with mounting the fuel tank on the body. Therefore, assemblability of the mounting table is improved.
