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. 2 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 normal rotation direction in which pruned branches and leaves as a material to be crushed are input by a drive source 3 that receives the power of a vehicle traveling engine (not shown) and outputs a driving force, and an internal tree. 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 is exposed to the opening end of the storage drum 2, and the tree chip in the storage drum 2 is stored from the opening end of the seal pipe 5. It functions to prevent spilling out of the drum 2.
[0008]
In addition, a flow guide 6 is provided at the rear end of the vehicle body 1 so as to be close to the opening end, and this flow guide 6 functions as a chute when discharging the wood chips in the storage drum 2 to the outside. To do.
[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. 3, the crusher 7 has a pair of cutter devices 9 and 10 in which a plurality of cutter blades are arranged in the horizontal direction for each of the upper and lower two 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]
Between the pair of brackets 11 on the side where the hopper 8 is provided with respect to the cutter blades 9a and 10a, that is, on the input side of the material to be crushed, for example, comb-shaped scrapers 12 and 13 as shown in FIG. It is fixed by fastening members S such as bolts over two upper and lower stages (two places).
[0014]
And each protrusion T which is a tooth | gear of each of these scrapers 12 and 13 has faced the front-end | tip part to each outer periphery of the collars 9b and 10b between each cutter blade 9a and 9a and between 10a and 10a.
[0015]
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 dimensions differ from those shown in FIG. Comb-shaped scrapers 14 and 15 having the same function are fixed by a fastening member S in two upper and lower stages.
[0016]
And each protrusion T which is a tooth | gear of each of these scrapers 14 and 15 has faced the front-end | tip part to each outer periphery of the collars 9b and 10b between each cutter blade 9a and 9a and between 10a and 10a.
[0017]
In the garbage truck with a crusher having such a configuration, the material to be crushed which is placed on the hopper 8 and then pushed in the direction of the crusher 7 is immediately guided up and down while being guided by the plate portions of the scrapers 12 and 13. It is inserted between the stage cutter devices 9 and 10.
[0018]
For this reason, each cutter blade 9a, 10a is crushed into chips while continuously scraping the material to be crushed between them.
[0019]
The crushed chip-shaped material to be crushed is fed into the storage drum 2.
[0020]
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.
[0021]
In such a case, the cutter devices 9 and 10 are driven so as to reverse the upper and lower cutter blades 9a and 10a with respect to the normal rotation direction (the crushing rotation direction) so far by a switch operation or the like.
[0022]
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.
[0023]
Then, during the returning operation, the biting state is released, and the upper and lower scrapers 12 and 13 on the inlet side scrape or scrape the material to be crushed which is returned and moved.
[0024]
Therefore, the operator can crush the material to be crushed by changing the direction of the material to be cut between the cutter blades 9a and 10a rotated in the normal direction.
[0025]
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.
[0026]
In addition, when it is determined that crushing is physically difficult, crushing of the material to be crushed is stopped.
[0027]
[Problems to be solved by the invention]
However, in such a conventional refuse collection vehicle with a crusher, chip-like material to be crushed generated by crushing by the cutter blades 9a and 9b is mainly transferred into the storage drum 2 by the scrapers 14 and 15 on the delivery side. In addition to being sent out, the chips are spilled downward from between the cutter blades 9a, 9a and 10a, 10a, and the gap between them and the collars 9b, 10b. There were problems such as falling and depositing on the floor of a wooden floor or a support stand, and finally soiling the site with sap.
[0028]
The present invention solves the above-mentioned problems, and can collect chip-like material to be crushed in the vicinity of the cutter device, which is not sent from the vicinity of the cutter blade of the cutter device into the storage drum, and falls directly downward. A dust collection vehicle with a crusher that can prevent scattering, accumulation and contamination of the material to be crushed around the crusher, and collect the chip-shaped crush material collected as needed. The purpose is to obtain.
[0029]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the garbage collection vehicle with a crusher according to the present invention is provided near the opening end of a dust collecting storage drum mounted on a vehicle body and crushes the material to be crushed from the outside.

[0032]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a garbage collection vehicle with a crusher according to the present invention, which is provided near the opening end of a dust collecting storage drum 2 that is mounted on a vehicle body 1 and rotates, and is to be crushed from outside. Is crushed by the crusher 7A and sent into the storage drum 2. In the crusher 7A, a pair of a plurality of cutter blades 9a and 10a arranged in a horizontal direction for each of the two upper and lower stages so as to be relatively rotatable, and the cutter blades 9a and 10a at each stage are alternately arranged. The cutter apparatus 9, the improper input removing member 17 and the scraper 15 disposed on the material input side and the delivery side of the material to be crushed with respect to the lower cutter apparatus 9, and below the inappropriate input material removing member 17 and the scraper 15, respectively. The chip-shaped material to be crushed installed and crushed in each space is provided with spill prevention members 18 and 19 for preventing the chips from spilling downward.
Further, the lower end of the spill prevention member 19 on the input side is rotatably supported by a pair of left and right brackets 11, 11 that support the horizontal axis of the cutter blades 9 a, 10 a, and the upper end is detachable from the inappropriate input material removing member 17. It is locked to.
This will be described in more detail with reference to FIG.
[0033]
As shown in the figure, in the crusher 7A of the present invention, each of the upper and lower stages in the same cutter apparatus 9 and 10 in which a plurality of cutter blades 9a and 10a are arranged in parallel in the upper and lower two stages. The plate-like improperly charged material removing members 16 and 17 are arranged on the material to be crushed side so that the tip and the reinforcing bent portion are close to the cutter blades 9a and 10a.
[0034]
Since the tip portions and the bent portions of these improper charge removing members 16 and 17 do not face between the cutter blades 9a and 9a and between the collars 9b and 10b between the cutter blades 9a and 10b, the scrapers 12, 13 are used. Although not having the function as described above, the material to be shredded is scraped off or scraped by touching the normally large material to be shredded returned to the input side when the cutter blades 9a and 10a are reversed. To function.
[0035]
On the other hand, between the pair of brackets 11, 11 on the left and right sides, below the scraper 15 and the inappropriate input removing member 17, the cutter blades 9 a, 9 b are crushed by the cutter blade 9, and the inside of the storage drum 2 through the scraper 15. There are provided spill prevention plates 18 and 19 for storing chip-like materials to be spilled directly downward without being fed into the storage.
[0036]
Of these spill prevention plates 18, 19, the spill prevention plate 19 is supported so that the lower end portion, which is the base end portion, is rotatable about a support shaft 20 attached to the bracket 11 or the like.
[0037]
A ring-shaped metal fitting 21 attached to the upper end (tip) of the spill prevention plate 19 is detachably locked to a locking tool 22 fixed to the improper charging material removing member 17.
[0038]
In addition, the same code | symbol is attached | subjected to the other component same as what was shown in FIG. 3, and the duplicate description is abbreviate | omitted.
[0039]
Therefore, in the garbage truck with a crusher configured as described above, the material to be crushed placed on the hopper 8 and then pushed in the direction of the crusher 7A is guided by the improper input material removal members 16 and 17 in two directions. It is inserted between the stage cutter devices 9 and 10.
[0040]
For this reason, the cutter blades 9a and 10a of these cutter devices 9 and 10 continuously scrape the pressed material to be crushed into chips.
[0041]
In addition, the chip-like member to be crushed thus crushed is fed onto the scraper 15 and fed into the storage drum 2 from here.
[0042]
At this time, since the upper and lower scrapers 14, 15 have the protruding pieces T as teeth facing the collars 9b, 10b between the cutter blades 9a, 9a and 10a, 10a, each cutter blade 9a. , 10a and the collars 9b, 10b act to scrape off the chip-like material to be crushed.
[0043]
And, it is not fed into the storage drum 2 along the scraper 15 but falls directly between the cutter blades 9a, 9a and 10a, 10a, or the cutter blades 9a, 10a and the scrapers 14, 15 and improper input material. The chip-like material to be crushed that falls directly between the removal members 16 and 17 is stored inside the spill prevention plates 18 and 19.
[0044]
On the other hand, over time, chip-like material to be crushed accumulates on the inside of each spill prevention plate 18, 19 and eventually becomes full. The chip-shaped material to be crushed is taken out and discarded or put into the storage drum 2.
[0045]
In this case, the metal fitting 21 at the end of the spill prevention plate 19 is removed from the locking tool 22 attached to the improper input removing member 17 and the spill prevention plate 19 is opened around the support shaft 20 at the base end (clockwise rotation). The chip-shaped material to be crushed in the region surrounded by the spill prevention plates 18 and 19 and the pair of brackets 11 can be taken out and put into the storage drum 2. it can.
[0046]
Further, by periodically opening the spill prevention plate 19, it is possible to take out the chip-like material to be crushed inside the spill prevention plate 19 and prevent it from becoming full. The interior can always be kept clean, for example.
[0047]
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 parts in the bracket 11.
[0048]
The spill prevention plate 18 can be arbitrarily configured to be opened and closed in the same manner as the spill prevention plate 19.
[0049]
However, even when each of the spill prevention plates 18 and 19 is filled with chip-shaped material to be crushed, the material to be crushed on the upper part is sent back into the storage tank 2 while being scraped up by the lower cutter 10a. It is.
[0050]
Even when the spill prevention plates 18 and 19 are provided, the chip-shaped material to be crushed may fall downward from between the cutter devices 9 and 10 and the storage drum 2.
[0051]
In such a case, it is desirable to install a bucket 23 having a relatively large area below the cutter devices 9 and 10 and the storage drum 2.
[0052]
In this case, it is desirable to install the bucket 23 in a fixed manner, to allow it to be transported by pulling out, or to be transferred to a transporting vehicle by tilting.
[0053]
In addition, it is also arbitrary that this bucket 23 is installed in the lower part of the flow guide 6 as shown in FIG.
[0054]
【The invention's effect】
As described above, according to the present invention, in the crusher, a plurality of cutter blades are arranged in parallel so as to be relatively rotatable in each of the upper and lower two stages, and the cutter blades of each stage are alternately arranged. A pair of cutter devices, an improper input material removing member and a scraper disposed on the material input side and the output side of the material to be crushed relative to the lower cutter device, respectively, and installed in the lower space of the improper input material removing member and the scraper, respectively. It is equipped with a spill prevention member that prevents the crushed chip-like material to be spilled downward, so that the spill prevention member is not sent from the vicinity of the cutter blade of the cutter device into the storage drum. The chip-shaped shredded material that falls directly downward can be collected near the cutter device to prevent accumulation and contamination around the crusher, and if necessary, the chip-shaped shredded material can be removed. Effect is obtained that can yield.
Further, the chip-like member to be crushed by the scraper is fed into the storage drum.
Further, the improper charging / removing member can scoop up the improper charging material returned to the charging side when the cutter blade is reversed.
[0055]
Also, according to the present invention, the lower end of the spill prevention member on the charging side is rotatably supported by the bracket that supports the cutter blade shaft, and the upper end is detachably locked to the inappropriate input removing member. The chip-like material to be crushed in the spill prevention member can be taken out periodically and put into the storage drum by the operator's hand. By cleaning, it is possible to obtain an effect that dirt and corrosion such as a cutter blade and a collar can be avoided in advance.
[0056]
If a bucket for receiving chip-shaped material to be crushed that falls from between the crusher and the storage drum is disposed below the cutter device and the storage drum, facing the spill prevention member, the vicinity of the cutter device and the storage drum As a result, the chip-like, granular, and powder-like material to be crushed and scattered in the region including the vicinity of the inlet is more reliably collected.
