Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuse crusher for a refuse collection vehicle. 2. Description of the Related Art A conventional refuse collection vehicle has a single rotating shaft. For example, in the case of the invention described in Japanese Patent Publication No. 55-8402, a conveying screw is provided on the rotating shaft. The garbage is crushed while being transported and sent forward. Also, those described in Japanese Utility Model Publication No. 3-280001.
In the attached link chain or flexible elongated member to the rotating shaft, breaks the dust by inertia, has been provided a crusher structure crushing. [0003] In the above-mentioned conventional garbage truck, since the garbage is roughly crushed and then pushed into the storage section, a gap is formed between the garbage and storage efficiency is low. In addition, the crusher is rough crushing, in the case of the hotel's structure of fine crushing the longer the entire structure,
The garbage storage space was cut down, reducing the amount of storage. Change
In, crushing machine, will be closing the and out of the garbage storage drum, it is a small outlet at the time of discharging the storage and trash
There was a case. In addition, in order to prevent the jumping out trash to the outside, there was also a need to or narrow the inlet. In view of the above, an object of the present invention is to provide a refuse crusher for a refuse collection vehicle that can perform continuous crushing with high efficiency, can store refuse at high density, and can easily discharge refuse. [0004] the door on both sides of the support frame fixed to an outer frame of the drum for garbage SUMMARY OF THE INVENTION mounted openably in a vertical direction, viewed engage blade each other in the lower portion of the door 2 to fit
The crusher body that is rotatably mounted on the
By mounting on the undercarriage to form a garbage crusher ,
The above problem has been solved. The present invention is constructed as described above, and the dust introduced from the inlet of the crusher main body is shredded by a blade provided on two shafts, and is cut into a drum. Is stored. When discharging, the door mounted on the support frame is opened upward to move the crusher body away from the discharge port and to easily discharge the shredded dust. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, dust is collected in an outer casing 2 mounted on a chassis 1 so as to be tiltable as shown by a chain line. the drum 3 can be rotated to a circle (see FIG. 2) is provided, the outer frame 4 in two support frame 5 ₁ provided on the outer periphery thereof, 5 ₂ and the fixed ends of both supporting frames 5 _1, 5 ₂ Support groove 6 provided inside
It is pivotally attached to the door 7 rotatably on _1, 6 _2. [0007] At the top of the _two vertical columns 8 ₁ , 8 ₂ ,
Is fixed so as horizontal upper cross-member 9 projects its ends from the strut _81, 82, in the center between the two struts _81, 82, the intermediate crosspieces 10 is fixed to the lower end, the lower end Cross member 11 is fixed
By struts ₈₁ between the intermediate crosspiece 10 and the lower crosspiece 11,
8 The _2, crusher body 12 is fixed, the door is configured
ing. [0008] The door 7 constructed as described above has two columns 8 ₁ ,
8 ₂ of the upper end is inserted into both supporting frame 5 _1, 5 ₂ support groove 6 _1, 6 _2, and is pivotally supported so as to be opened and closed vertically each pin 13. Then, both supporting frame 5 _1, 5 ₂ each support piece 14 ₁ outside the center, 14 ₂ projected to the support piece 15 _first U-shaped on the lower surface of both ends protruding of the upper lateral member 9, 15 ₂ the provided support piece 14 _1, 14 ₂ to the door opening and closing cylinders 16 _1,
16 pivotally attached to the _second lower end, the support piece 15 _1, 15 ₂ piston rod 17 _1, 17 ₂ of the front end is pivotally connected to, the pin 13 by operation of the two doors opening and closing cylinders 16 _1, 16 ₂ The door 7 can be opened and closed vertically at the center.
As shown in FIGS. 3 and 4, the crusher main body 12 is formed in a box shape, with a lower part protruding outward, and two shafts 1 inside.
8 ₁ and 18 ₂ are laid horizontally in parallel, and the driving source 1 provided outside
9 _1, 19 ₂ are driven respectively separately with. Two shafts 18
_1, 18 to ₂ at regular intervals, so that the mutually viewed engage the people each fixed number of blades 21 _1, 21 ₂ having a blade portion 20 that protrudes as shown in FIG. 4 in three positions . And
Blade 21 _1, 21 ₂ ..., 21 _1, 21 ₂ ... on the inner surface of the spacer 22 _1, 22 ₂ shredder body 12 each tip provided with arcuate portions along the axis 18 _1, 18 ₂ between fixed and <br/>. [0009] Also, crusher is the input side of the main body 12, as shown in FIG. 2, a number of rotating side wall on both sides to be able rotate the lower end as the axis is thus pivotally on pivot pin 23 24 ₁ …
24 ₂ ... are located <br/> As can engage each other by the projecting portion 25 provided at its end, and a lid 26 provided outside, at the time of introduction of refuse to open the lid 26, not When necessary, the rotating side walls 24 _1, ..., 24 ₂ on both sides are moved in the closing direction so that the cover 26 can cover the inlet . [0010] Incidentally, between the upper lateral member 9 and the intermediate crosspiece 10 of the door 7
The drum 3 side is closed by a shielding material 27, and the inside of the outer frame 4 is also closed by a shielding material 28. This embodiment is constructed as described above.
Before the dust is thrown in, the lid 26 is opened, and both drive sources 19 ₁ and 19 ₂ are operated to rotate both shafts 18 ₁ and 18 ₂ in the directions of arrows in FIG.
To the drum 3. When traveling, the rotating side walls 2 on both sides are used.
4 _1, crusher body 1 with the lid 26 by closing the 24 ₂
Cover the inlet of 2. When the dust is discharged after being transported to the predetermined place, the door opening / closing cylinders 16 ₁ and 16 ₂ are driven,
By opening the door 7 upward, a sufficient outlet is secured,
The outer casing 2 is inclined to discharge dust from the drum 3. Since the present invention has the above-described configuration and operation, the blade body 21 attached to the _two shafts 18 ₁ and 18 ₂
Dust is shredded while collecting garbage at ₁ , ₂ and collected on drum 3.
Because paid, can be housed in fine dust, it is possible to retract and a large amount of garbage at a high density, treatment after discharge is also simple. In addition, there is no possibility that dust will fly out . Further, at the time of discharging, by opening the door provided with the crusher upward, a discharge port for dust can be sufficiently secured and the dust can be easily discharged. [0015]
