DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood chip crusher for crushing mainly wood pieces such as pruned twigs and leaves to facilitate transportation or to use the crushed wood pieces for fuel and fertilizer. is there.

[0002]

2. Description of the Related Art Conventionally, this type of wood chip crusher has a crushing case in which a crushing device is built in a car body 3 having one front wheel 1 and two rear wheels 2 as shown in FIG. A crushing hopper 7 for feeding wood chips and the like into an internal crushing chamber is fixed to an upper portion of the crushing case 5. On one side of the crushing case 5, a discharge shutter 9 for discharging crushed pieces is mounted so as to open toward the side.
A connection port 13 for connecting the suction hose 11 is opened on the side surface of the crushing hopper 7 as necessary, and is closed by a suction port cover 14 when the suction hose 11 is not used. The inlet port 1 on the upper surface of the crushing hopper 7 is used to store the inlet port 15 for closing the inlet port 15 when not being used for storage or when working with the suction hose 11.
7 are provided. On the front of the crushing case 5, a cutting hopper 19 for supplying a long piece of wood or the like to the internal cutting chamber is provided.
Is provided.

[0003]

The conventional wood chip crusher is
Since the entire crushing hopper 7 is formed integrally and a large crushing hopper is required for the large amount of fallen leaves, the crushing hopper 7 protrudes largely to the side of the vehicle body 3 and the side width of the entire crushing machine becomes large and narrow. Passing through the place becomes difficult,
A large area was needed for storage.

[0004]

According to the present invention, there is provided an opening / closing plate for opening and closing an opening opening on one side of a hopper body of a crushing hopper, and an opening / closing plate fixed to both side edges of the opening / closing plate in a swinging direction. In some cases, the lower edge of the charging port body, which is formed of a shielding plate for shielding between both side edges of the opening / closing plate and both side edges of the opening, is swingably pivoted to the hopper body.

[0005]

In order to throw a piece of wood or the like into the crushing hopper and crush it, as shown in FIG. 3 (a), when the opening and closing plate is swung outward, the input is surrounded by the opening and closing plate and the shielding plate. Open mouth,
When fallen leaves, twigs, and the like are thrown into the inlet, they are crushed by the crushing device in the crushing case and discharged from the discharge shooter. When the opening and closing plate is swung inward to close the opening during transportation and storage, the side width is narrowed to facilitate transportation and storage.
