BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a garbage truck with a crusher.
[0002]
[Prior art]
The garbage truck with a crusher is configured, for example, to crush the branches and leaves produced by pruning roadside trees into chips with a crusher and store them in a storage drum mounted on a chassis.
[0003]
Further, a spiral blade is provided in the storage drum, and functions to feed branches and leaves crushed into chips, that is, tree chips, into the storage drum when the storage drum is rotated forward.
[0004]
FIG. 3 shows an example of the garbage truck with a crusher. This garbage truck with a crusher has a storage drum 2 on the vehicle body 1 that is selected and rotated in the forward direction and the reverse direction. .
[0005]
Incidentally, the storage drum 2 has a forward rotation direction and a crushed tree in which the pruned branches and leaves that are the material to be crushed are fed by a drive source 3 that receives the power of an engine (not shown) for driving the vehicle and outputs a driving force. The chip is selectively rotated in the reverse direction for discharging the chip to the outside.
[0006]
In the storage drum 2, a base end is continuously connected to the inner peripheral wall of the storage drum 2, and a tree chip which is dust according to the rotation direction of the storage drum 2 while the upper end faces the axial center line a side of the storage drum 2. A pair of spiral blades 4 for feeding or discharging.
[0007]
A seal pipe 5 is provided at a rear end of the spiral blade 4, that is, a portion that faces the opening end of the storage drum 2, and the tree chip in the storage drum 2 is externally connected to the seal pipe 5 from the opening end. It functions to prevent it from falling into the water.
[0008]
A flow guide 6 is provided at the rear end of the vehicle body 1 so as to be close to the opening end. The flow guide 6 serves as a chute for discharging the wood chips in the storage drum 2 to the outside. Function.
[0009]
Further, a crusher 7 is provided in the vicinity of the flow guide 6, and a folding hopper 8 is disposed behind the crusher 7.
[0010]
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 parallel in each of the upper and lower two stages, and each of the upper and lower stages. The cutter blades 9a and 10a are alternately arranged.
[0011]
These cutter blades 9a and 10a are supported by a single horizontal shaft (not shown), and the collars 9b and 10b, which are integrally provided at the center of the cutter blades 9a and 10a, are rotated by receiving power from the drive source or the like. Has been.
[0012]
Reference numeral 11 denotes a bracket that rotatably supports the left and right ends (both ends) of each horizontal axis.
[0013]
Also, scrapers 12 and 13 having a laminated block structure are respectively attached between the left and right brackets 11 and 11 at positions where the cutter devices 9 and 10 are sandwiched from above and below.
[0014]
The scrapers 12 and 13 include a plurality of plate-shaped steel blocks 14 having two scraped portions P1 and P2 having a pointed mountain shape, and a plurality of strip-shaped steel blocks 15. As shown in FIG. 5 and FIG. 6, they are alternately stacked and integrated.
[0015]
In the garbage truck 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 inclined surfaces q1 and q1 facing the scrapers 12 and 13, respectively. The cutter blades 9a and 10a are immediately inserted between the upper and lower cutter devices 9 and 10 while being guided by the cutter, and the cutter blades 9a and 10a are crushed into chips while continuously scraping the material to be crushed between them. I will do it.
[0016]
On the other hand, the chip-like material to be crushed in this way is sent out toward the opening end of the storage drum 2, and at this time, each scraping part P1 located on the sending side of each scraper 12,13. However, it functions to scrape and scrape the chip-like material to be crushed between the cutter blades 9a and 9a and between 10a and 10a.
[0017]
Moreover, if the material to be crushed is too hard or too soft, it may be caught between the upper and lower cutter blades 9a and 10a, or may be entangled, and may not be smoothly delivered to the delivery side.
[0018]
In such a case, the cutter apparatuses 9 and 10 are driven so as to reverse the upper and lower cutter blades 9a and 10a with respect to the respective normal rotation directions (crushing rotation directions) by a switch operation or the like.
[0019]
As a result, the material to be crushed between the upper and lower cutter blades 9a and 10a is returned as an inappropriate input material in the direction opposite to the input direction.
[0020]
Then, the biting state is released during the return operation, and the scraping portions P2 of the scrapers 12 and 13 on the upper and lower stages on the inlet side scrape or scoop the material to be crushed which is returned and moved. take.
[0021]
Therefore, if the material to be crushed is changed in direction or the like and is again inserted between the cutter blades 9a and 10a rotated in the forward direction, the material can be crushed.
[0022]
At this time, the scrapers 12 and 13 prevent the material to be crushed from being wound into the delivery side during the reverse rotation.
[0023]
[Problems to be solved by the invention]
However, in such a conventional garbage truck with a crusher, the scrapers 12 and 13 are constructed by laminating and assembling steel blocks 14 and 15, so that the structure is strong and does not cause displacement or deformation. Although it is advantageous in terms of weight, there is a problem that the assembly work is troublesome due to its large weight, and the cost is high.
[0024]
In addition, there is a problem that the chip-like material to be crushed sent from each scraping portion P1 of each scraper 12, 13 is not smoothly guided to the opening end of the storage drum and falls and scatters in the vicinity.
[0025]
However, if a guide member is installed below the scraping portion P1, the above-described dropping and scattering can be prevented, but the installation structure becomes complicated.
[0026]
The present invention solves the above-mentioned problems, and by arranging a guide plate and a plate-shaped scraper continuous therewith on the delivery side of the chip-shaped material to be crushed, an intended chip-shaped substrate is provided. To obtain a garbage collection vehicle with a crusher that can continuously and smoothly perform the scraping work of the crushing material and the guidance of the scraped chip-like crushing material in the delivery direction with a lightweight and low-cost configuration. Objective.
[0027]
[Means for Solving the Problems]
In order to achieve the above object, a garbage collection vehicle with a crusher according to the present invention is provided near the open end of a storage drum for collecting dust that is mounted on a vehicle body and rotates, and crushes material to be crushed from the outside. In a dust collecting vehicle with a crusher that is crushed into chips by a machine and sent into the storage drum, the crusher is arranged side by side so that a plurality of cutter blades can rotate relative to each other in two horizontal stages. And a pair of cutter devices in which the cutter blades of each stage are alternately arranged, and the comb blades are interposed between the adjacent cutter blades of the lower stage and arranged from the opening end of the storage drum toward the inside of the storage drum. It is characterized by comprising a plate-shaped scraper and a guide plate that is continuously provided on the scraper and guides the chip-shaped material to be crushed by the comb teeth into the storage drum. .
