Further, a spiral blade is provided in the storage drum, and when the storage drum is rotated in the forward direction, the storage blade functions to feed the crushed branches and leaves, ie, tree chips, into the storage drum. .

FIG. 2 shows an example of the above-mentioned refuse collection vehicle equipped with a crusher. The refuse collection vehicle equipped with a crusher has a storage drum 2 on a vehicle body 1 which is selected and rotated in a forward direction and a reverse direction. are doing.

[0005] Incidentally, the storage drum 2 receives a power of an engine (not shown) for driving the vehicle and outputs a driving force. It is selectively rotated in the reverse direction to discharge the internal tree chips to the outside.

In the storage drum 2, a base end is continuously provided on an inner peripheral wall of the storage drum 2, and while the upper end is directed toward the axis a of the storage drum 2, dust is generated according to the rotation direction of the storage drum 2. It has a pair of spiral blades 4 for feeding or discharging barrel tree chips.

A seal pipe 5 is provided at the rear end of the spiral blade 4, that is, at a portion located at the open end of the storage drum 2.
The seal pipe 5 functions to prevent tree chips in the storage drum 2 from spilling out of the storage drum 2 from the open end.

A flow guide 6 is provided at the rear end of the vehicle body 1 so as to be adjacent to the opening end. The flow guide 6 is used to discharge tree chips in the storage drum 2 to the outside. Functions as a shoot.

Further, a crusher 7 is provided so as to be adjacent to the flow guide 6, and a folding hopper 8 is disposed behind the crusher 7.

On the other hand, as shown in FIG. 3, the crusher 7 has a pair of cutter devices 9 and 10 in which a plurality of cutter blades are arranged in a horizontal direction for each of two upper and lower stages. The upper and lower cutter blades 9a and 10a are arranged alternately.

Incidentally, these cutter blades 9a, 10a
Collars 9b, 10b provided integrally at these central portions
Are supported by one horizontal shaft (not shown), and are rotated by receiving power from the drive source or the like.

Reference numeral 11 denotes a bracket for rotatably supporting the left and right ends (both ends) of each horizontal axis.

As shown in FIG. 4, for example, between the cutter blades 9a and 10a, on the side where the hopper 8 is provided, that is, between the pair of brackets 11 on the side where the material to be crushed is introduced, a tooth-shaped scraper 12, 13 is the upper and lower two-stage (two places)
Is fixed by a fastening member S such as a bolt.

Then, each of the scrapers 12, 13
Each of the protruding pieces T, which are the teeth of the collar 9b, faces the outer periphery of each of the collars 9b, 10b between the cutter blades 9a, 9a and between 10a, 10a.

On the other hand, on the side where the storage drum 2 is provided with respect to the cutter blades 9a and 10a, that is, on the delivery side of the material to be crushed into chips, the shape and shape shown in FIG.
Comb-shaped scrapers 14 and 15 having different dimensions but substantially the same function are fixed by a fastening member S over two upper and lower stages.

Then, each of these scrapers 14 and 15
Each of the protruding pieces T, which are the teeth of the collar 9b, faces the outer periphery of each of the collars 9b, 10b between the cutter blades 9a, 9a and between 10a, 10a.

In the refuse collection vehicle with a crusher having such a configuration, the material to be crushed placed on the hopper 8 and subsequently pushed toward the crusher 7 is immediately guided by the plate portions of the scrapers 12 and 13. , Two-stage upper and lower cutter devices 9 and 10
It is put in between.

For this reason, the cutter blades 9a and 10a crush the material to be crushed pressed between them into chips while continuously scraping the material.

The crushed chip-shaped material to be crushed is sent out into the storage drum 2.

If the material to be crushed is too hard or too soft, the material to be crushed becomes the upper and lower cutter blades 9a, 10a.
There is a case where it is caught in the middle or gets caught up and is not smoothly sent to the sending side.

In such a case, each of the cutter devices 9, 10 is driven such that the upper and lower cutter blades 9a, 10a are reversed in the normal rotation direction (crushing rotation direction) by a switch operation or the like. I do.

Thus, the upper and lower cutter blades 9a, 10a
The material to be crushed that is caught in between is returned as an unsuitable input material in a direction opposite to the input direction.

At the time of this return operation, the above-mentioned biting state is released, and the above and below each of the scrapers 1 on the insertion port side are released.
2, 13 scrape or scoop the crushed material that is returned and moved.

Therefore, the operator can crush the material to be crushed by changing the direction and so on, and throwing it again between the normally rotated cutter blades 9a and 10a.

At this time, each of the scrapers 12 and 13 prevents the material to be crushed from being caught in the delivery side during the reverse rotation.

When it is determined that crushing is physically difficult, crushing of the material to be crushed is stopped.

[0027]

However, in such a conventional refuse collection vehicle with a crusher, each cutter blade 9
The chip-shaped material to be crushed generated by the crushing by the a and 9b is mainly sent out into the storage drum 2 by the scrapers 14 and 15 on the sending side, and also between the cutter blades 9a and 9a and between the cutter blades 9a and 10a. Are these and color 9
b, 10b, etc., spilled downward from the gap, etc., and these chip-shaped materials to be crushed fall on the floor or the support base around the crusher 7 and accumulate, and finally, the site is contaminated with sap or the like. There were challenges.

The present invention solves the above-mentioned problem, and the chip-like material to be crushed which is not sent into the storage drum from the vicinity of the cutter blade of the cutter device but falls directly downward is provided near the cutter device. Garbage with a crusher, which can prevent the crushed material from scattering, accumulating and generating dirt around the crusher, and collectively collect the chip-shaped crushed material as needed. The purpose is to get a collection vehicle.

[0029]

In order to achieve the above object,

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side sectional view of a main part of a refuse collection vehicle equipped with a crusher according to an embodiment of the present invention.

As shown in the figure, the crusher 7A of the present invention
, A plurality of cutter blades 9a,
In the same cutter devices 9 and 10 having juxtaposed 10a as described above, a plate-shaped unsuitable side is placed on the input side of the material to be crushed so that the tip portion and the reinforcing bent portion are close to the upper and lower cutter blades 9a and 10a. The input material removing members 16 and 17 are arranged respectively.

The tip portions and the bent portions of these unsuitable input material removing members 16 and 17 are provided at the respective cutter blades 9a and 9a.
It does not have the same function as the scrapers 12 and 13 because it does not face the vicinity of the collars 9b and 10b between the collars 10a and 10b. It functions to touch and crush the crushed material in the form of the material to be crushed.

On the other hand, a pair of left and right brackets 11,
11 and below the scraper 15 and the unsuitable material removing member 17, they are crushed by the cutter blades 9 a and 9 b and do not feed into the storage drum 2 via the scraper 15 but spill directly downward. Spill prevention plates 18 and 19 for storing chip-shaped materials to be crushed are provided.

The spill prevention plates 18, 19
Among them, the spill prevention plate 19 has a lower end serving as a base end rotatably supported about a support shaft 20 attached to the bracket 11 or the like.

The ring-shaped metal fitting 21 attached to the upper end (tip) of the spill prevention plate 19 is detachably locked by a locking tool 22 fixed to the unsuitable material removing member 17.

The same components as those shown in FIG. 3 are denoted by the same reference numerals, and redundant description will be omitted.

Therefore, in the dust collector equipped with a crusher having such a configuration, the material to be crushed which is placed on the hopper 8 and subsequently pushed in the direction of the crusher 7A is the unsuitable material removal member 1.
While being guided by 6, 17, the upper and lower two-stage cutter device 9,
It is thrown in between ten.

For this reason, the cutter blades 9a and 10a of the cutter devices 9 and 10 crush the pressed material to be crushed into chips in a continuous manner.

The chip-shaped crushed member thus crushed is sent out onto the scraper 15, and is sent out from the scraper 15 into the storage drum 2.

At this time, the upper and lower scrapers 14, 1
5 has a projection T as a tooth facing the vicinity of the collars 9b, 10b between the cutter blades 9a, 9a and between 10a, 10a.
It acts to scrape off the chip-shaped material to be crushed attached to 10b.

The cutter blades 9a, 9a are not fed to the storage drum 2 along the scraper 15.
The chip-shaped crushable material that falls directly between the blades 10a, 10a, or directly between the cutter blades 9a, 10a, the scrapers 14, 15 and the unsuitable material removing members 16, 17 is formed of the above-described chip-shaped crushed material. It is stored inside each of the spill prevention plates 18 and 19.

On the other hand, as time elapses, the chip-shaped material to be crushed accumulates inside each of the spill prevention plates 18 and 19 and finally fills up. The chip-like material to be crushed inside is taken out and thrown into the storage or storage drum 2.

In this case, the metal fitting 21 at the end of the spill prevention plate 19 is detached from the locking tool 22 attached to the unsuitable material removing member 17, and the spill prevention plate 19 is attached to the support shaft 20 at the base end.
By opening around (turning clockwise),
The chip-shaped material to be crushed in a region surrounded by the spill prevention plates 18 and 19 and the pair of brackets 11 can be taken out, and can be put into the storage drum 2.

Further, by periodically opening the spill prevention plates 19, the chip-shaped material to be crushed accumulated inside the spill prevention plates 19 is taken out to prevent the spill prevention plates 19 from becoming full. It is possible to always keep the inside clean by also cleaning sap and the like.

As a result, it is possible to prevent rust from being generated in the cutter blades 9a and 10a, the collars 9b and 10b, and the respective parts in the bracket 11.

It is optional that the spill prevention plate 18 can be opened and closed similarly to the spill prevention plate 19.

Even if the spill prevention plates 18 and 19 are filled with the chip-shaped material to be crushed, the material to be crushed stacked on the upper portion is again scraped up by the lower cutter 10a, and the storage tank 2 is re-established. It is sent inside.

The spill prevention plates 18, 1 as described above are used.
Even in the case where 9 is provided, the chip-shaped crushed material may fall downward from between the cutter devices 9 and 10 and the storage drum 2.

In such a case, the cutter device 9,
It is desirable to install a bucket 23 having a relatively large area below the storage drum 10 and the storage drum 2.

In this case, it is desirable that the bucket 23 be fixedly installed, be pulled out so that it can be transported, or be tilted so that it can be transferred to a transport vehicle.

Incidentally, the bucket 23 can be arbitrarily installed below the flow guide 6 as shown in FIG.

[0054]

As described above, according to the present invention, a plurality of cutter blades are arranged in a crusher in a horizontally rotatable manner in each of two upper and lower stages, and each cutter in each stage is rotatable. A pair of cutter devices in which the blades are alternately arranged, and provided on at least one of the input side and the delivery side of the crushed material with respect to the lower cutter device, the crushed chip-shaped crushed material falls down. Since a spill prevention member and a spill prevention member are provided, a chip-like crushed material that falls directly on the fruit report without being sent into the storage drum from near the cutter blade of the cutter device can be collected near the cutter device, It is possible to prevent accumulation and dirt around the crusher, and to collect the accumulated chip-like material to be crushed as necessary.

Further, according to the present invention, the spill prevention member is configured to be openable and closable so that the chip-shaped material to be crushed accumulated therein can be discharged, so that the spill prevention member is sequentially deposited in the spill prevention member. The material to be crushed can be taken out periodically and poured into the storage drum by the operator's hand, and the inside can be cleaned in a timely manner to remove any stains such as cutter blades and collars. The effect is obtained that corrosion can be avoided beforehand.

Further, according to the present invention, by disposing a bucket for receiving the chip-shaped material to be crushed falling from between the cutter device and the storage drum below the lower cutter device, the vicinity of the cutter device and the storage device can be improved. The effect is obtained that the chip-shaped, granular, or powdery material to be crushed that falls and scatters into the area including the vicinity of the charging port of the drum can be more reliably recovered.
