DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a refuse collection vehicle equipped with a crusher.

[0002]

2. Description of the Related Art A garbage truck equipped with a crusher is constructed, for example, in such a manner that branches and leaves produced by pruning a street tree are crushed into chips by a crusher and stored in a storage drum mounted on a chassis. ing.

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. 3 shows an example of the refuse collection vehicle with a crusher. The refuse collection vehicle 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 the power of a vehicle running engine (not shown) and outputs a driving force. The driving source 3 outputs a driving force. It is selectively rotated in the reverse direction to discharge the extracted 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 the tree chips in the storage drum 2 from spilling outside from the open end.

Further, a flow guide 6 is provided at the rear end of the vehicle body 1 so as to be adjacent to the above-mentioned opening end, and this flow guide 6 is used to discharge tree chips in the storage drum 2 to the outside. Acts 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. 4, 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 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.

Further, scrapers 12 and 13 having a laminated block structure are mounted between the left and right brackets 11 and 11 at positions where the cutter devices 9 and 10 are sandwiched from above and below.

These scrapers 12 and 13 are composed of a plurality of plate-shaped steel blocks 14 having two pointed mountain-shaped scraping portions P1 and P2, and a plurality of strip-shaped plate-shaped steel blocks. 15 and alternately integrated as shown in FIG. 5 and FIG.

In the refuse-collecting vehicle with a crusher having such a configuration, the material to be crushed placed on the hopper 8 and then pushed in the direction of the crusher 7 has two opposite inclined surfaces of the scrapers 12 and 13. While being guided by q1 and q1, they are immediately inserted between the upper and lower two-stage cutter devices 9 and 10, and each of the cutter blades 9a and 10a continuously scrapes the material to be crushed pushed between them to insert chips. Crush into a shape.

On the other hand, the chip-like crushed material thus crushed is sent out toward the open end of the storage drum 2, and at this time, each scraper located on the delivery side of each of the scrapers 12 and 13 is used. The removing portion P1 functions to scrape and scoop up the chip-shaped material to be crushed that appears between the cutter blades 9a, 9a and between 10a, 10a.

If the material to be crushed is too hard or too soft, the material to be crushed will be 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 by a switch operation or the like such that the upper and lower cutter blades 9a, 10a are reversed with respect to the respective forward rotation direction (crushing rotation direction). .

Thus, the upper and lower cutter blades 9a, 10a
The material to be crushed interposed therebetween 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 upper and lower scrapers 12, 1 on the input port side are disengaged.
Each of the scraping portions P2 of 3 scrapes or scoops the crushed material that has returned and moved.

Therefore, the crushed material can be crushed by re-inserting it between the normally rotated cutter blades 9a and 10a by changing the direction of the crushed material.

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.

[0023]

However, in such a conventional refuse collection vehicle with a crusher, each of the scrapers 12, 13 is formed by laminating and assembling steel blocks 14, 15, and has a structure. Although it is strong, it is advantageous in that it does not cause displacement or deformation, but its heavy weight makes assembly work cumbersome, and also has the problem of being expensive.

Further, there is a problem that the chip-shaped material to be crushed delivered from each scraping portion P1 of each of the scrapers 12, 13 is not guided smoothly to the opening end of the storage drum, and falls and scatters in the vicinity. there were.

If a guide member is provided below the scraping portion P1, the above-mentioned falling and scattering can be prevented, but the mounting structure becomes complicated.

The present invention has been made to solve the above-mentioned problems, and a desired chip is provided by disposing a guide plate and a plate-shaped scraper connected to the guide plate on the delivery side of the chip-shaped material to be crushed. A garbage truck equipped with a crusher that can continuously and smoothly perform the scraping work of the material to be crushed and the guidance of the scraped chip-shaped material to be sent in the sending direction with a lightweight and low-cost configuration. The purpose is to gain.

[0027]

In order to achieve the above object,
In the garbage collector with crusher according to the present invention, a plurality of cutter blades are arranged in the crusher in a horizontally rotatable manner relative to each other in two upper and lower stages, and the respective cutter blades in each stage are alternately arranged. A pair of cutter devices, on the delivery side of the chip-shaped material to be crushed, interposed between each adjacent lower cutter blade,
A plate-shaped scraper having comb teeth that scrapes out the chip-shaped crushed material between these cutter blades is provided, and the chip-shaped crushed material scraped out by the comb teeth is connected to the scraper. A guide plate for guiding to the collection side is provided.
